Description
Technical field
The present invention relates to a kind of child's safety seat for vehicle, the height of headrest that especially relates to a kind of child's safety seat for vehicle is adjustedJoint mechanism.
Background technology
Along with the reinforcement that the head of a family realizes by bus to children's safety, the use of child safety seat on automobile becomes more and more generalAnd. Children are growing tall every day, and along with the growth of height, original child safety seat using cannot meet safety and relaxSuitable instructions for use, and at present common its height of headrest of child safety seat generally cannot regulate, this just mean along withThe growth of child's height, the seat that must more renew, to meet the requirement of safe handling, causes waste; Minority headrest adjustable is highThe child safety seat of degree, all more complicated of its governor motion, need when adjusting first headrest to be disassembled, then carry out highlyRegulate, operation is used inconvenience.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of child's safety seat for vehicle simple in structure, easy for operationHeight of headrest governor motion.
The present invention solves the problems of the technologies described above adopted technical scheme:
A height of headrest governor motion for child's safety seat for vehicle, comprises the chair back and is arranged on the headrest on the chair back, described headrestOn be provided with adjusting yoke, described adjusting yoke comprises leading portion pull bar, stage casing pull bar and back segment pull bar, described leading portion pull barBe arranged on the front end of described headrest, described stage casing pull bar and back segment pull bar are arranged on the rear end of described headrest, described inThe width of section pull bar is greater than the width of described back segment pull bar, is vertically provided with the first groove on the described chair back, and described firstOn groove, be provided with the location groove that multiple with described stage casing pull bar matches, the width of described location groove is greater than describedThe width of the first groove, the width of the first described groove is slightly larger than the width of described back segment pull bar, described back segment pull barOn tail end, be provided with the retaining mechanism for described adjusting yoke position is locked, described retaining mechanism is arranged on described chairThe rearward end of the back of the body, under locking positioning state, stage casing pull bar is placed in location groove, by retaining mechanism by headrest and the position of the chair backBe locked.
On described headrest, be provided with drawbar height governor motion, described drawbar height governor motion comprises and is vertically arranged on headThe second groove on pillow and be arranged on the drawbar height adjustable plate on the second groove both sides, the second described groove leads to described firstThe position of groove is corresponding, and the width of the second described groove is slightly larger than the width of described stage casing pull bar, and described drawbar height is adjustedOn joint plate, be provided with multiple teeth groove, the inner face of described leading portion pull bar is provided with the positioning tooth matching with described teeth groove, instituteThe back segment pull bar of stating and stage casing pull bar are successively through described the second groove and the first groove, and under locking positioning state, positioning tooth is putIn teeth groove, stage casing pull bar is placed in location groove, and the tail end of back segment pull bar is locked by retaining mechanism. Adjusting yoke canBe adjusted at the position on headrest by drawbar height governor motion, increased the scope that height of headrest regulates, make this children's safetyThe applicable the range of age of seat is more wide in range, meets multiple age bracket children's instructions for use.
Described location groove comprises location groove and lower location groove, and described upper location groove and lower location groove are respectivelyBe arranged on the two ends up and down of the first described groove. Because adjusting yoke can relatively be rested the head on and carried out the adjustment of upper-lower position, therefore fixedThe height of headrest that the two ends up and down that position groove only need be arranged on the first groove just can meet large span regulates, and has simplified manufacturing process,Reduce manufacturing cost.
On described back segment pull bar, be provided with external screw thread, described retaining mechanism is locking knob, on described locking knob, establishesBe equipped with the internal thread matching with described external screw thread, by coordinating described adjusting yoke and headrest of external screw thread and internal threadPosition be locked. This locking mechanism structure is simple, and part is few, and production cost is low, is easy to assembling.
Described leading portion pull bar and the cross section of stage casing pull bar are rectangle, and the cross section of described back segment pull bar is circular. KnotStructure is simple, be easy to processing.
The length sum of the first described groove and the second described groove is 200mm. The child safety seat of this structure, headPillow height degree can rise to 420mm from 220mm, meets neonatal to 7 year old children's use, has saved family expense.
The material of described adjusting yoke is ABS, PP or nylon. The cost of material is low for these, is conducive to reduce manufactureCost.
The material of described adjusting yoke is ABS. The cost of material is low for ABS, and hardness is good, and long-term service wear is little.
Compared with prior art, the invention has the advantages that: this height of headrest governor motion, simple in structure, carry out height and adjustWhen joint, only need slightly discharge retaining mechanism, adjusting yoke is pulled out slightly, from the groove of location, draw completely to stage casing pull barGo out, now back segment pull bar is placed in location groove, because the width of back segment pull bar is less than the width of locating groove and the first groove,Back segment pull bar can move up and down in the first groove, now moves up and down height adjusting yoke, and headrest is under the drive of adjusting yokeBe adjusted to desired height, inwardly promote height adjusting yoke, make stage casing pull bar enter into location groove corresponding to position, lockingMechanism lock fastens, and the position that highly regulates handle and headrest is fixed, and without headrest is disassembled, can complete headrestThe adjusting of height, easy for operation, the part of use is also less, is conducive to reduce production costs.
