Figure 14 (c) illustrates under the state keeping forwards tractive bank control bar 55a, state when seat main body 30 is forwards slided.That is, this action is, makes the tilting action that seat main body 30 tilts relative to bearing block 20.During tilting action, rotation lock shotpin 51 engages with lock groove 25b.Figure 14 (d) is, make seat main body 30 forwards slide after, namely tilt after, make the action that seat main body 30 is fixed relative to bearing block 20.That is, by release bank control bar 55a, thus make bank control bar 55a rearward location restore, tilt lock shotpin 50 to be inserted in the locking hole 25a in front and to engage.

When being described spinning movement, the state toward the front that Figure 15 (a) is seat main body 30, and for not operating state during bank control bar 55a and swivel lever 55b.Tilt lock shotpin 50 engages with the locking hole 25a of the central authorities among three that arrange in the longitudinal direction, and rotation lock shotpin 51 engages with the lock groove 25b in left side.Figure 15 (b) illustrates state during forwards tractive swivel lever 55b, and illustrates state when rotation lock shotpin 51 is moved upward and is removed with the engaging of lock groove 25b.

Figure 15 (c) illustrates under the state keeping forwards tractive bank control bar 55a, state when making seat main body 30 revolve turnback around the rotation axis R of tilt lock shotpin 50.That is, this action is, seat main body 30 is rotated relative to bearing block 20, and by seat main body 30 from state toward the front to the spinning movement towards rearward Status Change.During spinning movement, tilt lock shotpin 50 engages with locking hole 25a.Figure 15 (d) is, after making seat main body 30 rotation, makes the action that seat main body 30 is fixed relative to bearing block 20.That is, by release swivel lever 55b, thus swivel lever 55b rearward location restore, and rotation lock shotpin 51 to be inserted in another lock groove 25b and to engage.

If summarized for the leaning device of child seat 1 and rotating mechanism, then in child seat 1, there is as engagement section bearing block 20, as the engaged part engaged with engagement section, there is seat main body 30, described bearing block 20 has the bearing block 20 of lower coupling pole 41 and top pipe link 43, described seat main body 30 has bottom and is engaged guide member 40 and top is engaged guide member 44, when changing obliquity and the rotary seat main body 30 of seat main body 30, maintain engagement section and the engaging between engaged part.That is, the relative position relation of these parts is fixed all the time.Therefore, child seat 1 is compared with having the existing child seat of leaning device and rotating mechanism, can simple mechanism by the less and parts miniaturization of number of components, and independently make seat main body tilt with the position of rotation of the seat main body 30 relative to bearing block 20.

In addition, because the bottom of the rise part 22 of the bottom in child seat 1, i.e. seat bottom 31 and bearing block 20 is configured with leaning device and rotating mechanism, therefore when the tilting action of seat main body 30 and spinning movement time, seat main body 30 is stably supported relative to bearing block 20, its result is, can stably operate.In addition, owing to being configured with leaning device and rotating mechanism in the bottom of the rise part 22 of bearing block 20, therefore, it is possible to freely utilize the top of the rise part 22 of bearing block 20.

Further, due to when the tilting action of seat main body 30 and spinning movement time, leaning device and rotating mechanism are not exposed to outside, and therefore there will not be the situation thus excellent in safety clipping to finger etc., in addition, aesthetic appearance is also good.

In addition, due in child seat 1, tilt lock shotpin 50 and rotation lock shotpin 51 are formed point body component separately and operate independently, therefore compared with the situation selecting tilting action and spinning movement like that according to the overhang of single lock pin with the child seat such as described in patent documentation 1, can by simple mechanism reliably and stably operate.And, due to the change without the need to implementing overhang according to required operation, therefore compared with the child seat described in patent documentation 1, the working accuracy of all parts of leaning device and rotating mechanism and assembly precision require not tight, its result is, can reduce component costs and manufacturing cost.

In addition, in during tilting action and spinning movement, as long as the engaging between bearing block 20 with seat main body 30 can be maintained, then engagement section and engaged part can at random be formed.Such as can in the following way, that is, bearing block 20 only has bottom and is engaged guide member 40 and top and is engaged one party in guide member 44, and seat main body 30 has the side in corresponding lower coupling pole 41 and top pipe link 43.It can not be discoid that bottom is engaged guide member 40, but ring-type or polygonal shape.Bottom is engaged guide member 40 and top and is engaged guide member 44 and also can be integrally formed with seat main body 30.

Be engaged guide member 40 and top as bottom and be engaged connecting member between guide member 44, lower coupling pole 41, bar link 42 and top pipe link 43 can be integrally formed.And, although lower coupling pole 41, bar link 42 and top pipe link 43 are engaged guide member 40 and top and are engaged guide member 44 and engage in rise part 22 side and the bottom at the rear of the child seat 1 of seat main body 30, i.e. bearing block 20, if but can seesaw corresponding with the tilting action of seat main body 30 be carried out, then also can be other configuration.

Although be formed with three locking hole 25a on the cylinder curved surface 25 of bearing block 20, it also can be more than two or four.That is, corresponding with the quantity of locking hole 25a obliquity can be set to arbitrary quantity, and these positions may not be at equal intervals.In addition, although be formed with a pair lock groove 25b abreast with Central Line H on the cylinder curved surface 25 of bearing block 20, also can be formed and become arbitrary angle relative to Central Line H, such as orthogonal thereto lock groove.That is, except the state toward the front of seat main body 30 and except rearward state, can also be set to infant towards horizontal side towards horizontal side state.At this towards under the state of horizontal side, by arranging multiple locking hole in the horizontal, thus also tilting action can be carried out.

But, as mentioned above, in child seat 1, seat main body 30 can be made to tilt by tractive bank control bar 55a, seat main body 30 can be made by tractive swivel lever 55b to rotate.When supposing to implement these tilting actions and spinning movement, seat main body 30 will depict complexity and uncertain track simultaneously, thus there is the possibility of colliding with operator.Therefore, child seat 1 is configured to, and cannot implement tilting action and spinning movement simultaneously.

With reference to Figure 16 to Figure 18, the operating mechanism of bank control bar 55a and swivel lever 55b is described.Figure 16 is the figure be described the operating mechanism of child seat 1, Figure 17 be other figure, the Figure 18 be described the operating mechanism of child seat 1 is other figure be described the operating mechanism of child seat 1.In Figure 16 to Figure 18, top is the rear of seat main body 30, and below is the front of seat main body 30.

Operating switch 57 is the parts of thick plate-like, and is formed to have the shape of bending side, such as crescent or dartlike weapon shape.Operating switch 57 in the central portion office is installed on operator's station 55 in the mode that can rotate around set pin 57a by set pin 57a.On the side of bending outside, the i.e. rear side of the two end portions of operating switch 57, the front towards seat main body 30 is formed with the bearing surface 57b extended laterally.In addition, because operating switch 57 is covered from top by bank control bar 55a and swivel lever 55b, therefore cannot from outside by visual confirmation.

Control lever 56a is linked to bank control bar 55a by bar holding member 58a, and control lever 56b is linked to swivel lever 55b by bar holding member 58b.That is, the end of control lever 56a bends upward, namely bends vertically towards nearby direction with paper in the drawings, and the corresponding bar holding member 58a being formed L font is chimeric from top, namely vertically chimeric from nearby direction with paper in the drawings thus linked.Bar holding member 58b is also kindred circumstances.In addition, bar holding member 58a and bar holding member 58b also can be integrally formed with bank control bar 55a and swivel lever 55b respectively.

Next, the action of operating switch 57 is described.When the state from the operating mechanism shown in Figure 16, during below tractive bank control bar 55a forwards, namely in figure, bar holding member 58a forwards will move together with control lever 56a.Now, first top, the i.e. top end part of bar holding member 58a abut with the bearing surface 57b of operating switch 57, and operating switch 57 is rotated around set pin 57a.When continuing tractive bank control bar 55a, as shown in figure 17, bank control bar 55a abuts with the retainer 55c of operator's station 55 thus stops.

In this condition, the bearing surface 57b of the operating switch 57 of rotation abuts with the side of bar holding member 58a, and first top, the i.e. fore-end of another bar holding member 58b abut with another bearing surface 57b of operating switch 57.Therefore, the movement of swivel lever 55b is abutted with the bearing surface 57b of operating switch 57 by the top of bar holding member 58b and is prevented from.In other words, with under the state abutted with the side of bar holding member 58a at the bearing surface 57b of the operating switch 57 rotated, the mode that the top end part of another bar holding member 58b abuts with another bearing surface 57b of operating switch 57, and determine the crescent of operating switch 57 or the shape of dartlike weapon shape.

At tractive under the state (Figure 17) of bank control bar 55a, cannot tractive swivel lever 55b, otherwise, at tractive under the state (Figure 18) of swivel lever 55b, cannot tractive bank control bar 55a.When a side of the bank control bar 55a be pulled before or swivel lever 55b is back to initial position, bank control bar 55a or swivel lever 55b can forwards tractive.Therefore, according to this operating mechanism, the situation of leaning device and rotating mechanism action simultaneously can be prevented by simple mechanism, namely can realize alternative operation safely.

In addition, in child seat 1, due to the operation can implementing for the inclination and rotation carrying out seat main body 30 by means of only tractive bank control bar 55a or swivel lever 55b, therefore, it is possible to realize singlehanded operation, thus can freely use another hand.In addition, namely use one hand to operate operating mechanism, also can stably operate.

In addition, as mentioned above also can be in the following way, namely, a side in tractive bank control bar 55a or swivel lever 55b, even if do not make bar holding member 58a slide into operating switch 57 to abut with the side of bar holding member 58a, but when the top of bar holding member 58a makes operating switch 57 rotate, also limit another the slip in bank control bar 55a or swivel lever 55b.That is, operating switch 57 also can be the parts etc. of simple rectangle.In addition, the operating mechanism with aforesaid operations switch 57 can not only be applied to the field of child seat, can also be applied to the other field that existence realizes the requirement of alternative operation safely.

But, if during special reference Fig. 3, then as mentioned above, be formed with the opening 26 of rectangle on the top of the rise part 22 of bearing block 20.That is, in child seat 1, by leaning device and rotating mechanism being configured in the bottom of the rise part 22 of seat bottom 31 and bearing block 20, thus opening 26 can be formed on the top of the rise part 22 of bearing block 20.Opening 26 can be utilized as handle during carrying child seat 1.

In addition, in opening 26, as shown in Figure 4, the mechanism with various function or device 90 can be carried.Thus, bearing block 20 can have the function beyond the function of supported seat main body 30.Particularly at seat main body 30 towards under rearward state; can also be in the following way; such as, carry photographic camera and take still frame or animation, thus make preserver etc. can observe the situation of the infant taken a seat via vehicular telephone or auto-navigation system etc.In addition, also can carry screen, thus enable infant appreciate image.Further, also can carry loud speaker, thus enable infant appreciate sound.Further, also fan or interior environment system, illumination equipment etc. can be carried.Further, also can carry and in air, discharge isoionic plasma generation device by plasma discharge etc.According to this plasma generation device, can expect to obtain the sterilization of air, dedusting, sterilization, organic substance decomposing and deodorizing air cleaning effect or using infant and the hair of preserver or the hair nursing of the nursing of skin as object and the effect etc. of facial-care.In addition, in order to easily change these devices etc., also these devices etc. can be carried via fabricated section.

In order to use the electrical equipment being equipped on opening 26, the battery can be able to changed in the internal configurations of the bearing block 20 or cigarette lighter socket of vehicle also can be utilized using as power supply.In order to the tilting action and the spinning movement that make the feed cable from the power supply such as battery or cigarette lighter socket to electrical equipment can not interfere with seat main body 30, thus preferably with by below child seat 1 and the mode at the back side carry out connecting up or connecting up in the mode of the inside by bearing block 20.

In addition, certain opening 26 can be the shape beyond rectangle, such as, can be circular.In addition, opening 26 can run through towards rear and may also be only recess.And, above-mentioned this opening 26 can not only be applied to the child seat that can carry out relative to the tilting action of the seat main body of bearing block and the type of spinning movement, can also be applied to seat main body and be fixed in type in bearing block, seat main body with the type can installed relative to the mode of bearing block handling.

But, for child seat, from the protection infant when colliding not by the object of impact acting on vehicle, require higher impact resistance.Dent resistance by the child seat of the seat relative to vehicle after just colliding displacement, because of based on the counteraction of displacement after just colliding and the displacement etc. of the motion of the fitfull child seat caused verify.In order to realize higher impact resistance, child seat is preferably made to be firmly fixed on the seat of vehicle.The seatbelt of the fixing seat safety belt apparatus usually using the seat of vehicle to possess of child seat.The seat safety belt apparatus seat that the seat of vehicle possesses has safety strap, possesses the tongue piece of the hyoplastron being inserted with seatbelt, can fasten the clasp of throwing off hyoplastron.

To this with reference to Fig. 4, as mentioned above, child seat 1 is formed with safety strap engaging protrusion 27 at the rear portion of the left and right of the base portion 21 of bearing block 20.Safety strap engaging protrusion 27 is configured in, under the state of seat bearing block 20 being installed on vehicle, from the position that rear side engages with tongue piece or the clasp 91 of seat safety belt apparatus.In other words, safety strap engaging protrusion 27 across and a certain degree length and formed, so that can be different and tackle the position of different tongue piece or clasp 91 according to vehicle.In addition, as long as safety strap engaging protrusion 27 can engage with the tongue piece of seat safety belt apparatus or clasp 91, then the safety strap engagement groove of channel-shaped can be also set to.

The tongue piece of seat safety belt apparatus or clasp 91 are configured near the seat surface of the seat of vehicle usually, higher with the seatbelt phase specific rigidity of seat safety belt apparatus.Therefore, by making the tongue piece of this seat safety belt apparatus or clasp 91 engage with the safety strap engaging protrusion 27 of bottom of bearing block 20, particularly bearing block 20 or safety strap engagement groove being formed at child seat 1, thus bearing block 20 can be firmly fixed.Its result is, can realize higher impact resistance.

In addition, be preferably, safety strap engaging protrusion 27 or safety strap engagement groove are formed, the section shape vertical with length direction of that make to engage for tongue piece or clasp 91, between bearing block 20 and safety strap engaging protrusion 27 recess or safety strap engagement groove forms acute angle, can not misplace or come off to make tongue piece or clasp 91 but engage more reliably.In addition, safety strap engaging protrusion 27 or safety strap engagement groove also can not engage with tongue piece or clasp 91, but engage with the seatbelt of seat safety belt apparatus.Even if in this case, by the bottom of the bearing block 20 of fixing child seat 1, also can be fixed more firmly compared with existing child seat.Further, safety strap engaging protrusion 27 also can be formed as a point body component with bearing block 20.

Above-mentioned this safety strap engaging protrusion 27 or safety strap engagement groove can not only be applied to the child seat that can carry out relative to the tilting action of the seat main body of bearing block and the type of spinning movement, can also be applied to seat main body and be fixed in type in bearing block, seat main body with the type can installed relative to the mode of bearing block handling.

Child seat 1, in order to suppress seat main body 30 relative to the displacement of bearing block 20 and realize higher impact resistance, has the multiple supporting-point for impacting.That is, such as, when vehicle is from front and object collision, child seat 1 entirety is subject to front force of inertia upwards.Now, bearing block 20 is fixed by the seatbelt of vehicle, and in contrast, seat main body 30 is not fixed by the seatbelt of vehicle.Therefore, although seat main body 30 is for forwards displacement, abuts with bearing block 20 at supporting-point place seat main body 30 and supported, thus inhibit the displacement of seat main body 30.

To this with reference to Figure 10, in child seat 1, as mentioned above, be engaged guide member 44 by each top and the top of top pipe link 43 and engage, thus form supporting-point A.Namely, when making child seat 1 entirety be subject to front force of inertia upwards in the collision because of vehicle, each top of the top pipe link 43 that bearing block 20 side on the seat being directly fixed on vehicle configures is engaged guide member 44 towards rear to the top being configured in seat main body 30 side and supports.Its result is, when vehicle and object collision, inhibits seat main body 30 displacement forwards relative to bearing block 20.

Similarly, the supporting wall 28a inside the top ends that the top being installed in seat main body 30 is engaged collision areal of support 44b and the bearing block 20 that the outer peripheral face of guide member 44 is formed defines supporting-point B.In addition, the bottom that the upper surface 40d (Fig. 8) that the bottom being installed in seat main body 30 is engaged the ring-type of guide member 40 and the main body forming bearing block 20 receive the abutment wall 23a of opening 23 defines supporting-point C.In Fig. 10, supporting-point C is, the particularly rear end part in the bottom of the abutment wall 23a of bearing block 20 and bottom are engaged the rear end part of the upper surface 40d of guide member 40.

Supporting-point C according to the obliquity of seat main body 30 also can be, the left-right parts in the bottom of the abutment wall 23a of the ring-type of bearing block 20 and bottom are engaged the left-right parts of the upper surface 40d of guide member 40.Namely, the main body that the diameter that bottom is engaged guide member 40 is formed to be larger than bearing block 20 receives the width L (Fig. 5) transversely of opening 23, is all formed supporting-point C with the bottom of the abutment wall 23a of bearing block 20 with the upper surface 40d making bottom be engaged guide member 40 at any one obliquity place.Thus, in child seat 1, prevent the situation being accommodated in the seat main body 30 in main body reception opening 23 and coming off from bearing block 20.

By child seat 1, there is supporting-point A, B, C, thus inhibit particularly relative to the displacement of the seat main body 30 of bearing block 20, that is, inhibit seat main body 30 relative to bearing block 20 movement forwards.Its result is, can realize higher impact resistance.In addition, because supporting-point A, B, C are configured in the bottom of the seat bottom 31 of child seat 1 and the rise part 22 of bearing block 20, therefore bearing block 20 can more stably support seat main body 30.In addition, bearing block 20 by utilizing multiple supporting-point A, B, C carry out supported seat main body 30, thus impact is disperseed, therefore, it is possible to the material forming bearing block 20 and seat main body 30 is changed to lighter resin etc. from metal etc., thus can also reduce costs.

In addition, bearing block 20 and seat main body 30, without the need to abutting at supporting-point place all the time, also can adopt and slightly be separated and the mode that only abuts when colliding.In addition, child seat 1 can be configured to only have a supporting-point A, also can be configured to two supporting-point had in supporting-point A, B and C, can also be configured to have three supporting-point A, B and C.In addition, for realizing the supporting-point of higher impact resistance not now due to above-mentioned three parts.That is, the part of the seat main body 30 abutted with bearing block 20 can be engaged the lower portion office that the forward portion of guide member 44 and rear portion, the also bottom comprised compared with these forward portion and rear portion be on the lower engaged guide member 40 and at random forms comprising top.

With reference to Figure 19 to Figure 22, the height adjustment mechanism of baby safety band 70 (Fig. 1) is described.Figure 19 is the amplification stereogram at the back side of child seat 1, Figure 20 is the decomposition assembling figure of a part for the height adjustment mechanism of the baby safety band of child seat, Figure 21 is the figure be described the height adjustment mechanism of the baby safety band 70 of child seat 1, Figure 22 is another figure be described the height adjustment mechanism of the baby safety band of child seat 1.In addition, in Figure 19, backplate 68 described later omits diagram.

In child seat 1, in order to retrain infant safely relative to child seat 1, there is the baby safety band 70 that the width corresponding with the seatbelt that the seat of vehicle possesses is larger.Baby safety band 70 is configured in the left and right place of back-rest 32 front surface of seat main body 30 respectively, and baby safety band 70 about the body front place of infant is combined together.Therefore, baby safety band 70 runs through back-rest 32 from the rear of the back-rest 32 of seat main body 30 and forwards extends, and runs through the face of taking a seat, i.e. seat bottom 31 and extend downwards, and is fixed at the part place of the below of seat bottom 31.

The height needs of the position of the part of the back-rest 32 run through from the face of taking a seat of seat main body 30 to baby safety band 70, i.e. baby safety band 70 regulate according to the sitting height of infant.Therefore, in child seat 1, in order to the height adjustment mechanism suitably regulating the height of baby safety band 70 to have baby safety band 70.

Therefore, on the back-rest 32 of seat main body 30, be formed with two openings 36 extended on above-below direction, i.e. short transverse.These openings 36 are formed in symmetrical mode across the column sections 37 of the central authorities of back-rest 32, and in the height direction across and as baby safety band 70 height needed for scope and formed.Via these openings 36, the moving part 61 comprising above-mentioned head rest plate 60 be configured on the front surface of back-rest 32 is mounted in the mode can slided in the height direction relative to back-rest 32.

Moving part 61 has: head rest plate 60, and it is configured on the front surface of back-rest 32; Rotating bearing component 62, it is configured on the back side of back-rest 32, and is installed on head rest plate 60 via two openings 36 of back-rest 32; First engaging part 63, it is installed on rotating bearing component 62; Second engaging part 64, it is installed in the first engaging part 63.In addition, in fig. 20, rotating bearing component 62, first engaging part 63 and the second engaging part 64 relative to back-rest 32 and head rest plate 60, the enlarged icon slightly in order to make clear.In addition, because head rest plate 60 keeps baby safety band 70 via channel opening 60a, therefore constitute safety strap holding member, but also can be kept by other parts.

On head rest plate 60, in order to insert baby safety band 70, in the position that two openings 36 with back-rest 32 are corresponding respectively, be formed with two channel opening 60a with the width roughly the same with opening 36.Channel opening 60a respective above and near the central authorities of head rest plate 60, to be formed with via the opening 36 of back-rest 32 rearward outstanding installation portion 60b.In the respective below of channel opening 60a and near the central authorities of head rest plate 60, be formed with the engaged beam 60c of the beam-like rearward outstanding via the opening 36 of back-rest 32.At the respective top end of engaged beam 60c, be formed with the connecting hole 60d run through in the vertical direction.

On the left side of the channel opening 60a kept left and the right side of channel opening 60a of keeping right, be formed with the rearward outstanding and flat back plate 60e extended in the height direction of opening 36 via back-rest 32.Back plate 60e is formed the recess 60f of storage columned engaging rod 65 described later.In addition, be formed with two vent openings 60g in channel opening 60a more below separately, the height and position of described two vent openings 60g and head rest plate 60 has nothing to do and opens towards each opening of opening 36 all the time.

The protective bulkhead 62b of the rectangular flat shape that rotating bearing component 62 has housing 62a, give prominence to upward from housing 62a, from the rearward outstanding flat first knob 62c of housing 62a.Housing 62a by being installed on the installation portion 60b (Figure 19) of the head rest plate 60 outstanding by the respective opening 36 of back-rest 32, thus installs integratedly with head rest plate 60 and rotating bearing component 62.Now, between head rest plate 60 and rotating bearing component 62, be configured with the column sections 37 of back-rest 32.Protective bulkhead 62b prevents the hand of the operator when operating moving part 61 from touching the situation of the column sections 37 of seat main body 30.

First engaging part 63 has the main element 63a of box like.The back side of main element 63a is formed the opening 63b of rectangle.The top of main element 63a can be centered around the mode of the rotation axis rotation transversely extended with the first engaging part 63 and be installed on the housing 62a of rotating bearing component 62.In addition, in the bottom of main element 63a, court is extended with the engaging rod 65 of tubular to the left and right respectively.Engaging rod 65 has the stirrup 65a for strengthening inserted across left and right therein.Stirrup 65a is formed by metals such as carbon steel, but is not limited thereto.

At the back side of back-rest 32, be formed with engaged curved face part 38 in column sections 37, the left side of opening 36 kept left and the right side of opening 36 of keeping right.Engaged curved face part 38 has arrangement in the horizontal and is equally spaced configured with the structure of multiple concave curved surface in the height direction, and described concave curved surface is included in a part for the barrel surface transversely extended and entrance is formed comparatively large easily to receive the columned engaging rod 65 of concave curved surface.

By making the engaging of the first engaging part 63 rod 65 engage with the concave curved surface that the arbitrary transverse direction one of engaged curved face part 38 arranges, thus relative to back-rest 32, head rest plate 60 can be adjusted to arbitrary height and position.Now, the engaging rod 65 of the first engaging part 63 engaged with engaged curved face part 38 is also incorporated in the recess 60f of the back plate 60e of the head rest plate 60 slided in the height direction together with the first engaging part 63.In addition, the first engaging part 63, in the inside of rotating bearing component 62, the hand of rotation engaged with the engaged curved face part 38 of back-rest 32 at engaging rod 65 by the torsion spring 63c of left and right be integrally formed is biased.

Second engaging part 64 is, the parts of the tabular can slided along the vertical direction in the inside of the main element 63a of the first engaging part 63, and is biased downwards by coil spring 64a.In the lower end of the second engaging part 64, be formed in left and right from the main element 63a of the first engaging part 63 a pair engagement pin 66 outstanding downwards.Each engagement pin of engagement pin 66 by being inserted in the connecting hole 60d of the from the beginning engaged beam 60c that backup plate 60 is outstanding via opening 36, thus engages with head rest plate 60.In addition, the second engaging part 64 has the flat second knob 64b rearward outstanding via the opening 63b of the rectangle of the first engaging part 63.

With reference to Figure 21, the operation of the height regulating baby safety band 70 is described.Figure 21 is described above, the figure that the height adjustment mechanism for the baby safety band 70 to child seat 1 is described, and is the roughly longitudinal section by Width central authorities of seat main body 30, i.e. moving part 61.First, catch the first knob 62c of rotating bearing component 62 and the second knob 64b of the second engaging part 64, to the side's of being directed upwardly lift second knob 64b (Figure 21 (a)) of the first knob 62c simultaneously.That is, the second engaging part 64 is lifted upward relative to the first engaging part 63.Thumb as implemented in the following way, that is, is placed on the upper surface of the first knob 62c by this action case, forefinger and middle finger is contacted with the lower surface of the second knob 64b and lifts upward.By lifting the second engaging part 64 upward relative to the first engaging part 63, thus the engaging of the connecting hole 60d of the engaged beam 60c of the engagement pin 66 of the second engaging part 64 and head rest plate 60 is removed.Its result is, the first engaging part 63 becomes can carry out relative to rotating bearing component 62 state (Figure 21 (b)) that rotates.

Further, when proceeding the action of the second knob 64b lifting the second engaging part 64 upward, the first engaging part 63 rotates relative to rotating bearing component 62.Thus, the engaging of the engaged curved face part 38 at the engaging rod 65 of the first engaging part 63 and the back side of back-rest 32 is removed.Its result is, head rest plate 60 becomes the state (Figure 21 (c)) can slided in the height direction relative to back-rest 32.In this condition, by making the head rest plate 60 being inserted through baby safety band 70 in channel opening 60a slide in the height direction relative to back-rest 32, thus baby safety band 70 can be made to slide into required height.

Here, the second engaging part 64 is being lifted upward thus under the state of the engaging of engagement release pin 66 relative to the first engaging part 63, when making the first engaging part 63 rotate relative to rotating bearing component 62, limit the slip of the second engaging part 64 relative to the first engaging part 63.This is described with reference to Figure 22.Figure 22 is described above, other the figure that the height adjustment mechanism for the baby safety band to child seat 1 is described, and is the longitudinal section of the side that comprises the second engaging part 64.In fig. 22, for the component omission diagram beyond the first engaging part 63 and the second engaging part 64.

When with reference to Figure 22, be formed with locking protrusion 64c (with reference to Figure 20) in the side of the second engaging part 64, be formed with locking recess 62d in the inside of the housing 62a of rotating bearing component 62.From the state of Figure 22 (a), lift the second engaging part 64 (Figure 22 (b)) upward relative to the first engaging part 63, then, relative to rotating bearing component 62, first engaging part 63 is rotated.Thus, the locking protrusion 64 of the second engaging part 64 is sticked in the locking recess 62d (Figure 22 (c)) of rotating bearing component 62.Its result is, limits the slip of the second engaging part 64 relative to the first engaging part 63.

Therefore, even if hypothesis makes the lift power of the second knob 64b of the second engaging part 64 more weak in this condition, but due to the application force of coil spring 64a, engagement pin 66 also can not be given prominence to again.In other words, the second engaging part 64 after sliding upward is configured to safely, only otherwise under the state that engages with the engaged curved face part 38 of back-rest 32 of the engaging rod 65 being in the first engaging part 63, then the second engaging part 64 can not return to initial position.

After making baby safety band 70 slide into required height, in order to fix baby safety band 70 at this At The Height, thus only need implement above-mentioned a series of actions on the contrary.That is, relative to rotating bearing component 62, first engaging part 63 is rotated, engage with the engaged curved face part 38 of back-rest 32 to make the engaging of the first engaging part 63 rod 65.Thus, the engaging between the locking protrusion 64c of the second engaging part 64 and locking recess 62d of rotating bearing component 62 is removed.Then, relative to the first engaging part 63, second engaging part 64 is slided downwards, thus the engagement pin 66 of the second engaging part 64 is engaged with the connecting hole 60d of the engaged beam 60c of head rest plate 60.Assist, therefore, it is possible to implement like a cork because these actions are exerted a force by torsion spring 63c and coil spring 64a.

Height adjustment mechanism due to above-mentioned baby safety band 70 has the second engaging part 64 relative to engaging these two engagings relative to back-rest 32 of the engaging of head rest plate 60 and the first engaging part 63, even if therefore hypothesis has all been applied in impact to child seat 1 entirety, two have also been there will not be to engage the situation of throwing off.That is, the second engaging part 64 is removed relative to the engaging of head rest plate 60 and is implemented by movement upward, and the first engaging part 63 is removed by hand of rotation relative to the engaging of back-rest 32, namely implemented away from the movement on the direction of back-rest 32.Therefore, in order to remove these engagings, the direction of required power is roughly orthogonal.

In addition, the second engaging part 64 relative to head rest plate 60 engaging remove and the first engaging part 63 relative to back-rest 32 engaging remove by lift the second engaging part 64 the second knob 64b a series of continuous print action and implement.That is, by applying identical power upward to the second knob 64b of the second engaging part 64 all the time, two stage engaging can be removed.Therefore, the height adjustment mechanism of above-mentioned baby safety band 70 is easily implemented the mode of desired engaging releasing and is formed not easily to occur unexpected engaging to remove.

In addition, owing to making engaged curved face part 38 be formed on the central authorities of back-rest 32 while central authorities column sections 37 being retained in back-rest 32, therefore the intensity of back-rest 32 is maintained.In addition, because the concave curved surface of the engaged curved face part 38 of back-rest 32 is formed to be aligned to the mode of three row in the height direction, therefore the engaging of the first engaging part 63 rod 65 is prevented not to engage with the concave curved surface of a horizontal engaged curved face part 38 arrange, but situation about engaging from the concave curved surface of mutual highly different engaged curved face part 38.

In addition, as long as the height adjustment mechanism of baby safety band 70, i.e. travel mechanism can operate by referring to that action illustrated by Figure 21, then can at random form.Namely, as long as travel mechanism becomes following structure, then can at random form, described structure is, direction of slip is parallel with the direction of the power putting on the second engaging part, first carry out engagement release by the slip of the second engaging part, then carry out engagement release by the rotation of the first engaging part, thus become can sliding mode.In addition, above-mentioned height adjustment mechanism can not only be applied to the field of child seat, can also be applied to the other field that existence realizes this requirement of operation of travel mechanism safely.

But, for baby safety band 70, passing through above-mentioned height adjustment mechanism, according to the sitting height of infant suitably to after highly having carried out regulating, need the build according to infant and suitably the degree of tightening up of baby safety band 70, the length that namely extends to the front of back-rest 32 regulated.

With reference to Figure 23 and Figure 24 reference, the adjustment of length of the baby safety band 70 employing accommodation zone 75 is described.Figure 23 is the block diagram of the accommodation zone 75 of the extreme higher position representing child seat 1, and Figure 24 is the block diagram of the accommodation zone 75 of the extreme lower position representing child seat 1.Block diagram when Figure 23 and Figure 24 is the seat main body 30 observing child seat 1 from below.

The rear side that the back-rest 32 of seat main body 30 lived by the baby safety band 70 of left and right links together, and therefore, is made up of a safety strap.In addition, baby safety band 70, at the rear side of the back-rest 32 of seat main body 30, links with one end of the accommodation zone 75 of a wider width.That is, turn back in one end of accommodation zone 75, and turns back partly overlapping and being sewn nearby.Its result is, is formed with ring portion 75a in one end of accommodation zone 75.Baby safety band 70 is inserted with among ring portion 75a.Therefore, the ring portion 75a of accommodation zone 75 constitutes the connecting part with baby safety band 70.Accommodation zone 75 is by weaving and formed used material usual in the seatbelt of vehicle, such as poly-ester fibres, but be not limited thereto.

Accommodation zone 75 extends downwards along the back-rest 32 of seat main body 30, near the bottom being formed in seat main body 30, namely the opening 31c (with reference to Fig. 7) of the bottom of the trailing flank of the cylindrical portion 31b of seat bottom 31 enter in inner space 35.Then, when being described with reference to Fig. 9, enter into the accommodation zone 75 in the inner space 35 of seat main body 30, by the bottom surface that is formed in inner space 35 and safety strap support projection 33e outstanding upward and bend to acute angle and near the lower surface extending to upward seat cushions 34.

Then, after accommodation zone 75 extends abreast relative to seat bottom surface 33 toward the front in inner space 35, from be formed in seat bottom 31 cylindrical portion 31b leading flank top opening 31d (with reference to Fig. 7) and internally space 35 stretch out.Then, accommodation zone 75 extends from the opening 31e of leading flank of the frustum of a cone portion 31a being formed in seat bottom 31 towards the top of seat bottom 31.Then, accommodation zone 75 via be configured in operating mechanism operator's station 55 the belt adjuster 76 at rear and the front to seat main body 30 extends (Fig. 1), described operating mechanism is arranged on the front part office of the upper surface of seat bottom 31.

Belt adjuster 76 can carry out locking and the releasing of accommodation zone 75 by known mechanism.When during locking accommodation zone 75, accommodation zone 75 being made to move in the longitudinal direction relative to belt adjuster 76 by belt adjuster 76.On the other hand, when the locking of belt adjuster 76 is removed, accommodation zone 75 can be moved in the longitudinal direction relative to belt adjuster 76.

Next, the length adjustment of baby safety band 70 is described.The length adjustment of baby safety band 70 is implemented under the state of locking relieving belt adjuster 76.When the length for increasing the baby safety band 70 extended to the front of back-rest 32, can by forwards or the baby safety band 70 that extends to the front of back-rest 32 of top stretching and increasing.Finally, baby safety band 70 can be stretched till the rear side of the back-rest 32 at seat main body 30 does not have unnecessary part.Now, the length of the baby safety band 70 that the front to back-rest 32 extends is maximum, and the ring portion 75a of the accommodation zone 75 linked with baby safety band 70 is in extreme higher position (Figure 23).

The extreme higher position of accommodation zone 75 refers to, ring portion 75a is positioned at the position corresponding with the part being formed with channel opening 60a of the head rest plate 60 being inserted with baby safety band 70.Therefore, the height that regulates according to the height adjustment mechanism by baby safety band 70 of the extreme higher position of accommodation zone 75 and changing.

On the other hand, when the length for shortening the baby safety band 70 extended to the front of back-rest 32, the part (Fig. 1) of the accommodation zone 75 that the front can passing through forwards to stretch to seat main body 30 extends and shortening.Finally, till near the accommodation zone 75 that can stretch is configured in seat bottom 31 opening 31c until the ring portion 75a of the accommodation zone 75 linked with baby safety band 70.Now, the length of the baby safety band 70 that the front to back-rest 32 extends is the shortest, and the ring portion 75a of the accommodation zone 75 linked with baby safety band 70 is in extreme lower position (Figure 24).

The extreme lower position of accommodation zone 75 refers to, ring portion 75a is positioned at the position near the opening 31c of seat bottom 31.Therefore, the extreme lower position of accommodation zone 75 is fixed on the position of the opening 31c of seat bottom 31.

Thus, the baby safety band 70 that the length adjustment of baby safety band 70 is extended by the front stretched to back-rest 32 or the part of accommodation zone 75 that extends to the front of seat main body 30 and implement, thereby, it is possible to regulate the tie-down situation of the baby safety band 70 corresponding with the build of infant.

In child seat 1, accommodation zone 75 extends to the opening 31c place that is neighbouring, i.e. the bottom of the trailing flank of the cylindrical portion 31b of seat bottom 31, bottom of the rear side being formed in seat main body 30, and enters in inner space 35.Then, accommodation zone 75 is bent to acute angle and extends upward by safety strap support projection 33e.Therefore, accommodation zone 75 is not via shortest path towards belt adjuster 76, but is formed on roundabout path.Therefore, in child seat 1, by near the bottom that the extreme lower position of accommodation zone 75 to be configured in compared with existing child seat seat main body 30 on the lower, thus the distance between the extreme higher position of accommodation zone 75 and extreme lower position is ensured longer.Its result is, can expand the scope of the length adjustment of baby safety band 70 further.

In addition, in order to carry out the adjustment of accommodation zone 75 swimmingly, also pulley can be configured on the top of the part connected with seat main body 30, such as opening 31c.In addition, also can be set to the inside without accommodation zone 75 seat main body 30 and be through its lower surface that is outside, i.e. seat main body 30.

In addition, on the back side of the back-rest 32 of seat main body 30, backplate (wire harness panel) 68 is installed.Figure 25 is the amplification stereogram at the back side of child seat 1, and Figure 26 is the block diagram of the backplate 68 of child seat 1.Backplate 68 plays following effect, that is, cover in the mode making it to be formed obstruction the unnecessary baby safety band 70 of rear side of back-rest 32 and accommodation zone 75 that are configured in seat main body 30, and be accommodated in the back side of back-rest 23.In addition, backplate 68 plays following effect, that is, the engaged curved face part 38 of the both sides of the opening 36 of the part covering moving part 61 and the back-rest 32 being formed in seat main body 30 can not be exposed to make it.

Backplate 68 as shown in the longitudinal section of Fig. 9, with in the Width central portion office of seat main body 30 across and short transverse and the mode extended and configure, and to be mounted in the mode be embedded on seat main body 30.Backplate 68 has plate top 68a and plate bottom 68b.Backplate 68 is such as integrally formed to make it to have flexibility by injection molding by the resin material of polypropylene etc.Particularly, the plate top 68a of backplate 68 is formed thin-walled with the part on the border of plate bottom 68b compared with other parts, thus formed can the hinge 68c of alternating bending when not damaged.But backplate 68 also can omit hinge 68c and make it bend by its flexibility.In addition, baby safety band 70 and accommodation zone 75 are incorporated in the accommodation space 68d (Fig. 9) between seat main body 30 and backplate 68.

The upper end of backplate 68 engages with the back-rest 32 of seat main body 30, by removing this engaging, and centered by hinge 68c, makes plate top 68a bend towards rear, thus can open the accommodation space 68d between seat main body 30 and backplate 68.That is, backplate 68 local can be made away from back-rest 32.Such as, at regulating allocation when the redundance of the baby safety band 70 of the rear side of seat main body 30 etc., the plate top 68a of backplate 68 can be made to bend, thus open with operation easy to implement.

In addition, the plate top 68a of plate 68 overleaf, in Width central portion office across and short transverse and be formed with opening 68e.The width of opening 68e is greater than the width of the column sections 37 of the back-rest 32 of seat main body 30.Therefore, two openings 36 of back-rest 32 expose local via the opening 68e of backplate 68.Its result is, on the fore-and-aft direction of the back-rest 32 of seat main body 30, can guarantee aeration, can not feel well to make the infant taken a seat by two openings 36 of back-rest 32 and the vent openings 60g (Figure 20) of head rest plate 60.Further, form opening 68e by plate 68 overleaf, thus can operate moving part 61 under the state of having installed backplate 68.That is, the first knob 62c of rotating bearing component 62 and the second knob 64b place of the second engaging part 64 can be arrived via the opening 68e of backplate 68.

With reference to Figure 27 to Figure 29, baby safety band 70 is described.Figure 27 is the birds-eye view of a part for baby safety band 70, and Figure 28 is the lateral plan of the elongation state of the baby safety band 70 of Fig. 1, and Figure 29 is the lateral plan of the case of bending of the baby safety band 70 of Fig. 1.

Be used to the baby safety band 70 of child seat 1 to make there is flexibility and to be formed in the mode of multiple bands 71, such as two band 71a, 71b overlaps of safety band shape.Band 71a, 71b weave each via to usual the used material in the seatbelt of vehicle, such as poly-ester fibres and are formed.Band 71a, 71b are sewn along the many lines extended in the longitudinal direction, such as two line 71c.

When making baby safety band 70 bend, after release makes its bending power, still overcoming gravity and maintaining case of bending.That is, when making overlapping band 71 bend, the radius of curvature of the band 71a of bending inner side is less than the radius of curvature of the band 71b in bending outside.Due to the difference of this radius of curvature, circumferentially such as extend on the length direction of band 71 bending between the face of the inner side of the face in the outside of the band 71a in opposed inner side and the band 71b in outside, thus produce deviation.Then, when discharging the power making it bending, the band 71b in the outside of the elongation of baby safety band 70 is for returning to initial condition, but the face of the inner side of the face in the outside of the band 71a of inner side and the band 71 in outside is locked due to friction drag.Its result is, even if the baby safety band 70 be out of shape still overcomes gravity and maintains shape after releasing the power making it be out of shape.

Therefore, even if preserver removes baby safety band 70 and makes infant from after child seat gets off, baby safety band 70 still overcomes gravity and maintains shape, obstruction when again making infant take a seat after therefore can not becoming.Further, band 71a, 71b are formed by the material of the softness of poly-ester fibres etc., even if therefore infant or preserver contact or collide baby safety band 70 is also safe.

In addition, also in the following way, that is, with when making baby safety band 70 be out of shape, the mode of larger deviation can be produced between two bands 71a, 71b, loosely sewing up band 71a, 71b.In addition, also can in the following way, that is, baby safety band 70 is not by friction drag, but is inserted into inside by the metal filament of the shape after can maintaining distortion or metal sheet etc., thus maintains shape.In addition, the structure making baby safety band 70 entirety maintain shape in the above described manner can be adopted, also can adopt the structure maintaining shape locally.Further, also can at the part place of the baby safety band 70 abutted with infant, winding has the baby safety band cover 77 (Fig. 1) of resiliency.In this case, the structure maintaining shape relative to baby safety band cover 77 in the above described manner can also be adopted.Further, above-mentioned baby safety band 70 can not only be applied in the field of child seat, can also be applied to exist overcome gravity and maintain in the other field of the demand of the safety strap of shape.

With reference to Fig. 7 and Figure 30, the installation method of baby safety band 70 to seat main body 30 is described.Figure 30 is the front view of the baby safety band 70 of child seat 1.Particularly, baby safety band 70 shown in Figure 30 is, be provided with at its one end place by combining mechanism with the joint portion 78 (Fig. 1) that the baby safety band 70 of left and right is combined, and between the thigh being configured in infant, the baby safety band 70 of thigh safety strap.In the installation method installed to seat main body 30, the baby safety band 70 of left and right and the baby safety band 70 of thigh safety strap are all identical.The baby safety band 70 extended from the back-rest 32 of seat main body 30 and the baby safety band 70 of thigh safety strap, run through downward seat bottom 31 as mentioned above and be fixed at the part place of the below of seat main body 30.Therefore, as shown in Figure 7, in seat bottom 31, as making baby safety band 70 run through and the mounting portion of installing, the through hole construction opening 31f of rectangle is formed with in left and right and front and back.

In addition, form the top running through the band 71 of the baby safety band 70 of the seat bottom 31 of seat main body 30 and turn back, with nearby partly overlapping of turning back and together with being sewn to.Its result is, is formed with the ring portion 72 being formed ring-type on the top of baby safety band 70.

Then, columned hold-down bars 73 is inserted in the ring portion 72 of baby safety band 70 of the seat bottom 31 running through seat main body 30.Hold-down bars 73 is such as formed by cutting off the raw MAT'L of pole by metals such as carbon steel, but is not limited thereto.Hold-down bars 73 is formed to be larger than the construction opening 31f of the seat bottom 31 that baby safety band 70 runs through.That is, the length of columned hold-down bars 73 is greater than the lateral dimension of the construction opening 31f of rectangle, and the diameter of hold-down bars 73 is greater than the longitudinal size of construction opening 31f.Therefore, under the state being inserted in the ring portion 72 of baby safety band 70 by fixing side 73, baby safety band 70 can not be thrown off with seat main body 30.Be inserted into hold-down bars 73 in the ring portion 72 of baby safety band 70 be fitted together to by the engagement pawl 31g near the construction opening 31f that is formed in seat main body 30 by press-button type and be fixed.

Because baby safety band 70 is reliably fixed by being fitted together to of press-button type of hold-down bars 73, the below to seat main body 30 is therefore there will not be to hang down and become the situation of obstruction.In addition, if hold-down bars 73 be bar-shaped then also can not for cylindric, be not namely circular bench section.Hold-down bars 73 can be configured to the polygonal bench section with such as quadrangle and hexagon etc.

By cutting out the hold-down bars 73 of fixing baby safety band 70 from bar-shaped raw MAT'L, thus raw material expense and treating cost can be made to be dirt cheap.In addition, due to the simple structure of hold-down bars 73, therefore intensity is also very excellent.Further, due to relative to being fitted together to being fixed as simple press-button type of baby safety band 70 of seat main body 30 employing hold-down bars 73, therefore installation exercise is also very simple and easy.

With reference to Figure 31 and Figure 32, paulin mechanism 80 is described.Figure 31 is the block diagram on the top of child seat 1, and Figure 32 is the decomposition assembling figure of the revotating card locking mechanism 81 of the paulin mechanism 80 of child seat 1.

Paulin mechanism 80 is installed on head rest plate 60, and paulin mechanism 80 entirety is slided along with the slip on the above-below direction of head rest plate 60.Paulin mechanism 80 has revotating card locking mechanism 81, the paulin (not shown) covered on the head of infant, the fixing paulin pillar 82 becoming the skeleton of supporting paulin and the first movable paulin pillar 83 and the second movable paulin pillar 84.Revotating card locking mechanism 81 has the pair of posts support unit 85 in the part of the bending left and right being arranged on head rest plate 60, a pair first rotation latch for printed circuit 86, a pair second rotation latch for printed circuit 87.

The both ends of fixing paulin pillar 82 are fixedly installed on the column support member 85 of left and right.The both ends of the first movable paulin pillar 83 periodically rotate, namely can be locked to the mode of interim position of rotation can rotate latch for printed circuit 86 by first, and are installed on the column support member 85 of left and right.The mode that the both ends of the second movable paulin pillar 84 periodically rotate can rotate latch for printed circuit 87 by second is installed on the column support member 85 of left and right.

Therefore, the first movable paulin pillar 83 and the second movable paulin pillar 84 entirety can around the rotation axis of horizontal expansion forwards or rear periodically rotate.Therefore, it is possible to make paulin forwards launch or rearward fold.In addition, the angle of rotation that the first movable paulin pillar 83 can rotate compared with the second movable paulin pillar 84 is comparatively large, therefore, it is possible to more forwards launch compared with the second movable paulin pillar 84.

First rotates latch for printed circuit 86 has the first rotary end 86a being formed circle.In addition, the second rotation latch for printed circuit 87 has the second rotary end 87a be formed with the circle of the first rotary end 86a same diameter.Column support member 85 has the rotation supporting portion 85a that the first rotary end 86a and second being formed to rotate latch for printed circuit 86 with first rotates the circle of the second rotary end 87a same diameter of latch for printed circuit 87.The groove of U-shaped is formed through and the elastic beam 85b marked off in the central authorities of rotation supporting portion 85a.
