Description

Active chair headrest structure

Technical field

The utility model relates to automotive seat, specifically a kind of active chair headrest structure.

Background technology

Along with the raising of people's living standard, vehicle has entered among the increasing family.Vehicle runs into and knocks into the back or during head-on crash under steam, and human body head can be because action of inertia and falling backward.In this process, be easy to injure.A kind of active chair headrest structure that the utility model relates to is good terms of settlement for the problems referred to above.

Summary of the invention

The utility model aims to provide a kind of active chair headrest structure for solving existing problem.

In order to achieve the above object, the technical solution adopted in the utility model is, design a kind of active chair headrest structure, comprise that headrest, headrest bayonet socket plastic cement pipe, self-lubricating formula plastic casing-pipe, backrest skeleton main body, flexible connection sheet, retracing spring, backrest are subjected to force mechanisms and fixed plate, wherein, the left and right two ends of backrest skeleton main body are respectively equipped with the flexible connection sheet, two described flexible connection sheets connect the upper end of retracing spring respectively, and the lower end of described retracing spring connects backrest skeleton main body respectively; The upper end of backrest skeleton main body is provided with fixed plate, and described fixed plate is provided with two perforates; Two self-lubricating formula plastic casing-pipes are arranged in respectively in the perforate of fixed plate; Backrest is connected with the flexible connection sheet at the left and right two ends of described backrest skeleton main body respectively by the and arranged on left and right sides of force mechanisms; Backrest is subjected to the upper end of force mechanisms to be provided with two guide pipes, and described two guide pipes insert respectively in the described self-lubricating formula plastic casing-pipe; Two headrest bayonet socket plastic cement pipes insert in respectively in the guide pipe, and two mounting pipe of headrest lower end are connected with two described headrest bayonet socket plastic cement pipes.

The utility model is compared with prior art; when meeting with an accidet collision, vehicle can absorb collision energy effectively; initiatively draw close to finish initiatively protection action to human body head by headrest; human body resilience occiput in collision back is impinged upon on the headrest; protect human body head effectively, had big meaning for driving safety.

Description of drawings

Fig. 1 is front elevation of the present utility model.

Fig. 2 is left view of the present utility model.

Fig. 3 is birds-eye view of the present utility model.

Fig. 4 is STRUCTURE DECOMPOSITION scheme drawing of the present utility model.

Referring to Fig. 1,1 is headrest; 2 are headrest bayonet socket plastic cement pipe; 3 are self-lubricating formula plastic casing-pipe; 4 is backrest skeleton main body; 5 for flexibly connecting sheet; 6 is retracing spring; 7 are subjected to force mechanisms for backrest; 8 is fixed plate.

The specific embodiment

Now the utility model is further described by reference to the accompanying drawings.

1. referring to Fig. 1, that Fig. 1 shows is an embodiment of the present utility model.Comprise that headrest 1, headrest bayonet socket plastic cement pipe 2, self-lubricating formula plastic casing-pipe 3, backrest skeleton main body 4, flexible connection sheet 5, retracing spring 6, backrest are subjected to force mechanisms 7 and fixed plate 8, wherein, the left and right two ends of backrest skeleton main body 4 are respectively equipped with and flexibly connect sheet 5, two described flexible connection sheets 5 connect the upper end of retracing spring 6 respectively, and the lower end of described retracing spring 6 connects backrest skeleton main body 4 respectively; The upper end of backrest skeleton main body 4 is provided with fixed plate 8, and described fixed plate 8 is provided with two perforates; Two self-lubricating formula plastic casing-pipes 3 are arranged in respectively in the perforate of fixed plate 8; Backrest is connected with the flexible connection sheet 5 at described backrest skeleton main body 4 left and right two ends respectively by the and arranged on left and right sides of force mechanisms 7; Backrest is subjected to the upper end of force mechanisms 7 to be provided with two guide pipes, and described two guide pipes insert respectively in the described self-lubricating formula plastic casing-pipe 3; Two headrest bayonet socket plastic cement pipes 2 insert in respectively in the guide pipe, and two mounting pipe of 1 lower end of resting the head on are connected with two described headrest bayonet socket plastic cement pipes 2.

The utility model is installed in the automobile, and automobile runs in the process of moving and knocks into the back or during head-on crash, because action of inertia resilience backward, and human body back can be subjected to force mechanisms 7 collisions with backrest to human body, produces thrust backward in stressed back.When backrest is subjected to force mechanisms 7 to absorb collision energy; and up mobile and drive headrest 1 and initiatively draw close to finish initiatively protection action to human body head by guide pipe, can not make human body resilience occiput in collision back impinge upon on the headrest 1 (but rest the head on 1 initiatively cater to head dwindle collision distance).Stressed end back resets mechanism by retracing spring 6.

The utility model is compared with prior art; when meeting with an accidet collision, vehicle can absorb collision energy effectively; initiatively draw close to finish initiatively protection action to human body head by headrest 1; human body resilience occiput in collision back is impinged upon on the headrest 1; protect human body head effectively, had big meaning for driving safety.

Reach embodiment above by reference to the accompanying drawings and described embodiment of the present utility model; the structure that embodiment provides does not constitute restriction of the present utility model; those skilled in the art can adjust according to needs in this area, make various distortion or modification within the scope of the appended claims all in protection domain.
