Description

MOTOR VEHICLE HAVING A QUAT PLACES BENCH

TECHNICAL FIELD TO WHICH IRE * VENTK RELIES

The present invention relates generally to the arrangement of the passenger compartment of a motor vehicle.

It concerns more particularly a motor vehicle comprising a chassis, a seat mounted on the chassis, and two outer belts which are located on both sides ^of the seat and which each one equipped with a strap bolt.

BACKGROUND

Generally, a motor vehicle has two or three rows of seats,

The second row of seats is designed to accommodate a variable number of passengers, depending on the type of vehicle.

We thus know benches that can accommodate up to three passengers. Such a bench then delimits a central seat and two side seats located on either side of this central seat.

In this type of seat, the seat belts of the two side seats are of the "three-point attachment" type, in that the strap of each seat belt is attached to a first point on one side of the passenger's pelvis. Pass the passenger's pelvis to a second point and then back across the passenger's chest to a third point above the first point. Such a seat belt ensures a good support of the passenger in case of shock.

On the other hand, the seat-belt of the seat of the seat is of the "two-point fastening" type, in that the seat belt is fixed at a first point on one side of the basin and passes simply in front of the passenger's pelvis to a second point of attachment. Such a seat belt ensures a less effective maintenance of the passenger in case of impact,

Another disadvantage of this bench is that it offers the same place for passengers, whether there are one, two or three to sit on the bench (each with only one seat).

Also observed in some regions of the world a USE of unplanned bench in the sense that ^it happens that four passengers sit on the bench eôte to Coast, which generates a security problem since it is planned, only three places and therefore only three seat belts.

OBJECT OR-! / IWENI! ON

In order to overcome the aforementioned drawbacks of the state of the art, the present invention proposes a motor vehicle in which the seat has a great modularity.

More particularly, it is proposed according to the invention a motor vehicle as defined in the introduction, in which it is provided, on the one hand, two central safety belts which are located between the two said two external seat belts, at a distance of these, which each comprise a strap equipped with a bolt, and, secondly, at least four peduncles in which said bolts are adapted to be fixed.

Thus, thanks to the invention, the seat can simultaneously accommodate one, two, three or four passengers safely.

To seat up to four passengers, the bench does not delimit seats. His seat and his back are on the contrary generally flat. In this way, passengers can enjoy more space when there are less than four to sit on the seat.

Preferably, there are more peduncles than bolts mounted on the seat belts. Otherwise formulated, it is possible to anchor each safety belt bolt in one or the other of the peduncles, according to the number of passengers to sit on the seat,

Thus, passengers can use different seat belts and different pedicels depending on the number of passengers to sit on the seat. For example, when they are two, the ^passagei's will attach each with a seat belt through ia half of the seat, allowing them to enjoy all His place offered by the bench . This advantage will be well explained with reference to the figures,

Other advantageous and non-limiting features of the motor vehicle according to the invention are as follows:

~ there are provided two outer peduncles and four central peduncles located between and away from said outer peduncles;

^■ said four central peduncles are distributed in pairs;

- the two outer seat belts and the two central safety belts are three-point fastening; ^• the seat defining a seat surface, the central pédoncules- are movable between a use position in which they protrude from said seating surface and a retracted position in which they extend below the surface of 'seated ;

- The bench has a seat and a folder which are each monobloc;

^■■ the seat is fixed or articulated directly on the chassis;

- If there is provided a strap guide which defines two passages through which are respectively strung the straps of the two central seat belts;

- The strap guide is movably mounted on the bench so as to have an adjustable height relative to the upper edge of the bench.

DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT The following description with reference to the accompanying drawings, given by way of non-limiting examples, will make it clear what the invention consists of and how it can be achieved.

In the accompanying drawings;

- Figure 1 is a schematic perspective view of a seat of a motor vehicle according toventiôn;

FIG. 2 is a detailed view of the zone II of FIG. 1;

^"Figure 3 is a schematic front view of the strap guide of fa nquette of Figure 1; and

· ^■ Figures 4 to 6 are schematic front views of the seat of Figure 1 Sa on which are represented respectively two, three-layer and four passengers.

In a conventional manner, a motor vehicle 1 comprises a chassis 2 which notably comprises a floor, two side wings and a roof (see FIGS. 4 to 6).

This automobile vehicle here comprises two front seats (not shown) and a rear seat 10 (shown in Figure 1).

In the description, the terms "before" and "back" will be used with respect to this vehicle: automobile, the front of a component of the motor vehicle designating the side of this component which is turned towards the hood of the vehicle and the rear side designating the side of this component which is turned towards the trunk. In the same way, the "lower" and "upper" trusses will be used in relation to this automobile vehicle, the lower part of a component designating the part of this component which is situated on the side of the floor of the vehicle and the upper part designating the part of that component that is located on the roof side.

Although the invention is not limited to this type of vehicle, it will be considered here that the motor vehicle is of the "tri-body" type. A te! motor vehicle includes a chest, a passenger compartment and a cover which, vus- side form two unhooked, _the one at the bottom of the windshield and the other at the bottom of the rear window.

On this type of motor vehicle, the chassis comprises a metal shelf which extends between the two lateral wings, at the rear of the seat 10, at the junction between the rear window and the trunk,

As shown in FIG. 1, bench seat 10 comprises a seat 20 and a backrest 30,

Conventionally, the seat 20 and the backrest 30 each comprise a metal frame (not visible in the figures) covered with a pad for the comfort of passengers.

The seat 20 is directly mounted on the floor of the vehicle automobile. It is preferably mounted fixedly, by means of feet which, on one side, are welded to the frame of the seat, and which, on the other side, are screwed on the floor.

Alternatively, o could provide to mount the hinged seat, with a single tilt mobility forward, so as to fold the seat against the back of the front seats.

The backrest could be fixed on the seat or on the chassis of the vehicle,

Here, the backrest 30 is rather movably mounted on the seat 20, by means of a hinge allowing it to tilt forward.

The backrest 30 is thus movable between a position of use in which it extends vertically so that a passenger can sit on the bench 10, and a folded position in which it extends horizontally against the seat to to free up cargo space in the trunk of the vehicle. Preferably, the seat 20 and the backrest 30 are monobioc, in that they each comprise a rigid metal frame. The record 30 as the seat 20 does not sound! therefore not divisible: they are not intended here to be partially folded.

Preferentially, the upholstery of the seat 20 and that of the backrest 30 do not delimit any place in the seat. Otherwise formulated, the bench does not delimit separate seats for His passengers. The upholstery of the seat 20 and that of the backrest 30 delimit, on the contrary (on the front face of the backrest and on the upper face of stale), seating surfaces for the passengers who are uncomfortable.

The file 30 presents. a lower edge 31 which in the position of ^use, is turned toward the seat 20. It also has an upper edge 32 opposite (facing the roof of the motor vehicle), and two side edges (respectively facing the lateral wings of motor vehicle).

According to a particularly advantageous characteristic of the invention, the seat 10 is designed to accommodate up to four passengers simultaneously. The motor vehicle ^' 1 is for this purpose equipped with four seat belts and at least four anchoring means for safety belt bolt.

H comprises in this case two external safety belts 70, 80 which are situated on either side of the seat 10 and which each comprise a strap 71, 81 on which is threaded a bolt 73, 83, In this case each bolt comprises, on the one hand, a body which has a slot slipped on the strap, and, on the other hand, a plate which extends from the body and which is designed to lock in a peduncle.

The motor vehicle 1 also comprises two central safety belts 80, 80 which are located between the two outer seat belts 70, 60 at a distance therefrom and which each comprise a strap 51, 61 on which is threaded a bolt 53. 63.

it also comprises two external anchoring means 91, 92, which. are located on both sides of the bench 10.

It finally comprises at least two central anchoring means 93, 94, 95, 88, which are located between the two outer anchoring means 91 and 92 and at a distance therefrom.

Each seat belt 50, 80, 70, 80 is here of the three-point type of fixation. Each belt then comprises a winder 52, 62, 72, 82 attached to a structure part !! © of. motor vehicle, inside which is wound a portion of the strap 51, 61 _: 71, 81 of the seat belt.

The reels 72, 82 of the two outer seat belts 70, 80 are directly attached to the lateral wings of the motor vehicle, here by screwing. Alternatively, they could be fixed on the backrest itself, or on the floor of the vehicle.

The strap 71, 81 of each of the two outer belts 70, 80 emerges phrase ^the reel 72, 82, passes through a guide 74, 84 which is attached to one of the side wings of the motor vehicle (up to the upper edge of the backrest 30), then down to the floor where its free end is fixed.

As shown in Figures 1 and 2. the reels 52, 82 of the two central seat belts 60, 60 are attached to the rear shelf (not shown) of the frame, for example by screwing.

The strap 61, 81 of each of these two central seat belts 50, 60 emerges from the reel, passes through a webbing guide 100 (which will be described in more detail later in this presentation), then descends to Se floor where its free end is fixed. To go down to the floor, each strap 51, 61 passes either through a passage provided in the seat 20, or between the seat 20 and the backrest 30.

The bolts 53, 83, 73, 83 of the central seat belts 50, 60 and external 70, 80 are identical and are thus designed to be engaged and locked in ^one or other of the anchoring means 91, 92, 93, 94, 95, 96 provided at the seat 20 of the seat 10.

Conventionally, each anchoring means comprises a peduncle (which accommodates the bolt) mounted on a support (which allows to link the peduncle to the chassis of the vehicle).

According to a preferred feature of the invention, more peduncles 9, 92, 93, 94, 95, 96 are provided than bolts mounted on the seat belts 50, 80, 70, 80.

Otherwise formulated, when each seat belt 50, 80, 70. 80 is equipped with a single bolt 53, 63, 73, 83, it is expected more peduncles 91, 92, 93, 94, 95, 98 than belts 50, 80, 70, 80,

In this case, the motor vehicle has six peduncles 91, 92, 93, 94, 95, 96.

it is more precisely predict (besides the two outer peduncles 91, 92 located bet and the other of the seat 10} four central peduncles 93, 94, 95, 96, which are distributed in pairs along the seat 20, between the two outer peduncles 91, 92, at a distance from them.

The supports of the outer peduncles 9 ^* 1, 92 are here formed by rods fixed to the floor of the motor vehicle.

The supports of the central pedicels 93, 94, 95, 96 are each in turn common to two peduncles. Otherwise formulated, the two central pedicles 93, 94, 95, 96 of each pair are here fixed on the same support,

The two supports of these central pedicles 93, 94, 95, 96 are provided so that the four pedicels are retractable relative to its seating surface of the seat 10. In this way, when they are not used, these peduncles can be placed in the retracted position under your seating surface, so that a passenger can sit on top without being disturbed. On the contrary, when used, these peduncles can be placed in the projecting position above the seating surface, so that they are easily accessible.

here, these two supports are for this purpose formed by straps (not visible) connected to the floor of the car vehicle. The four pedicles are in turn provided for retraction-or in cavities dug in the seat 20 (see Figure 1), or at the junction between the seat 20 and the backrest 30.

As shown in Figure 4, when two passengers 200 of large body size wish to sit on the seat 10, they can thus refract its four central peduncles, and use the only central seat belts 50, 60, engaging their bolts in the seats. outer peduncles 91, 92,

To avoid being bothered by the outer seat belts 70, 80, the two passengers 200 can (before sitting down) tilt the backrest 30 forward so as to pass the straps 71, 81 of these two seat belts. external security 70, 80 at the back of the folder 30, before bringing the folder back to the use position. Hooks provided for this purpose at the back of the backrest 30 can facilitate the maintenance of the straps 71, 81 at the rear of the seat 10.

As shown in Figure 6, when four passengers 300, 400 of smaller body size wish to sit on the seat 10, they then use the four seat belts 50, 60, 70, 80 by engaging their bolts in the central peduncles 93, 94, 95, 96 /

As shown in FIG. 5, when three passengers 200, 300 of variable body size wish to sit on the seat 10, the one with the largest body size is installed as shown in FIG. 4, while the other two seats install in the manner shown in FIG.

As shown in FIG. 1, the bench 10 here also comprises exactly two headrests 40 which are fixed to the upper edge 32 of the backrest 30.

Conventionally, these festoons 40 each comprise a metal frame covered with a lining, and two parallel rods 41 which are welded to the armature of the filler 40 and which are slidably mounted in two sockets welded to the metal frame of the folder 30 {see Figure 1). In this way, the two headrests 40 are movable relative to the backrest 30, between a high position and a low position {against the backrest 30).

Each of the two aforementioned bushings, well known to those skilled in the art, is in the form of a sheath which is welded to the metal frame of the backrest 30, this sleeve lodges internally a plastic sheath which carries at its end upper a collar. This collar emerges on the outside of the backrest in order to define a passage for one of the parallel rods 41 of Tappukete 40. The sheath makes it possible to guide the squareness of this parallel rod 41. This sheath also comprises tabs of 'snap which are adapted to cooperate with notches provided on the parallel rods 1 to lock in height' headrest 40.

As shown in Figure 6, each headrest 40 has a width such that when the seat 10 accommodates four passengers 300, 400, it extends to the rear of the heads of two of the passengers 300, 400.

The aforementioned webbing guide 100 is mounted movably on the backrest 30, between the two headrests 40, so as to have a height h adjustable relative to the upper edge 32 of the backrest 30 (see Figure 2).

For this, as shown in Figure 3, the webbing guide 100 comprises mounting means 1 1.0 on the back 30, and a body 120 which defines two passages 125, 126 separate for the two straps: 51, 61 belts central safety 50, 80,

here, the body 120 is in the form of a rectangular plate, and the mounting means 110 are in the form of two rods 11 which Retend from the lower edge of the body 120 :,. perpendicular to it,

The body 120 and the x rods 111 are either formed of a single piece, by stamping ^a metal plate or assembled to form a single piece. It may be provided to cover the body 120 with a plastic skin, for example by overmolding the metal plate.

The two rods 1 1 1 are here identical to those fitted to the headrests 40. They are then slidably mounted in plastic sleeves housed in two sockets 35 welded to the metal frame of the backrest 30. These sheaths and sockets 35 Here again are identical to those accommodating the rods 41 of the headrests 40.

In practice, the webbing guide 100 can thus be mounted in place of a central headrest of a bench originally intended to accommodate three passengers only. This strap guide 100 is thus placed at equal distances from the two lateral edges of the backrest 30.

The body 120 is movable relative to the backrest 30, between a high position and a low position (bearing against the backrest 30).

As shown in Figure 3, the two passages 25, 126 defined by the body 120 ^¬ préféreniiellernent are at least partially superimposed vertically, one above the other,

In law, each of these two passages 125, 126 is in the form of a slit, of which a first portion 125A, 126A is slightly curved, and a second portion 1258, 128B is curved in a semicircle.

These two passages 125, 128 are positioned feast-spade one above the other.

Each passage 125, 126 presents: here an open contour. More specifically, each passage 125, 125 communicates with the outside of the strap guide 100, via an engagement slot 127, 128 which extends from the edge of the body 0 to the corresponding passage 25, 126.

This tent of engagement 127, 126 can insert ^or easily extrair a seat belt strap in the passageway 125, 126 corresponding.

As shown in Figure 4, when two passengers 200 of large body size wish to sit on the bench 0, not to be injured by the seals 51, 81 of the central seat belts 60, 60 in the event of impact, ifs can adjust the height of the strap guide 100, moving it Here in the high position.

As shown in FIG. 8, when four passengers 300, 400 of smaller body size wish to sit on the seat 10, so as not to be injured by the straps 51, 61 of the central safety belts 50, 80 in the event of an impact, they can adjust the height of the strap guide 100, moving here in the low position.

As shown in Figure 5, when three passengers 200, 300 of varying body sizes wish to sit on the seat 10, not to be injured by the straps. 81, 61 of the central seat belts 50, 60 in case of shock , the fatter passenger 200 uses the seat belt 50 which emerges from the highest passage 125 of the blood guide 100, while the other passenger uses the seat belt 80 which emerges from the lowest passage 128 of the guide The interest of having two passages 125, 126 superimposed is thus to allow each passenger to use a seat belt whose strap is correctly positioned in height relative to his shoulder.
