Abstract
The invention relates to a driving headrest with a hinge structure. The driving headrest with the hinge structure comprises a front headrest cover body and a back headrest cover body, wherein a hinge ejecting system is arranged on the upper part in the middle of the front headrest cover body and the back headrest cover body; a support rod fixing and activating system is arranged below the hinge ejecting system; a rack locking system is arranged between the hinge ejecting system and the support rod fixing and activating system; the support rod fixing and activating system consists of a support rod and a pull cable; the pull cable is positioned between the backrest of a chair and the hinge ejecting system; the support rod is fixed on the framework of the chair; the rack locking system consists of a fixed rack and a moveable rack; and the front headrest cover body is made of an energy-absorbing material. When a running vehicle is impacted, the driving headrest lifts and inclines forwards instantly to reduce the distance between the head of a passenger and the headrest at the moment of the impact so as protect a head; therefore, the turning angle of the head of the passenger is greatly reduced and damage to the neck of the passenger which is caused by throwing a whip is reduced or eliminated.
Description
Technical field
The invention belongs to manned vehicle headrest technical field, particularly relate to a kind of hinge arrangement SAHR.
Background technology
The effect of manned vehicle headrest generally is for improving a kind of auxiliary device that vehicle ride comfort and safety are provided with.Wherein safety mainly is passive protection.When the manned vehicle rear portion was clashed into, occupant's head can move to the rear portion with inertia.At short notice, when acceleration all was squeezed in fragile neck with the strength of slowing down, occupant's cervical vertebra can be subjected to bigger injury.The protection of headrest passive security exists weak point to be: at first, headrest has certain distance with occupant's head, when being subjected to impacting, can not play protective action when head has just begun to move; Secondly, headrest is fixed on the seat, and the strength of quickening when head touches headrest is also very big, can not in time play protective action.
Summary of the invention
Technical matters to be solved by this invention provides a kind of hinge arrangement SAHR, and is untimely to solve fixedly manned vehicle headrest protection, can not reduce the problem that cervical vertebra is hurt to greatest extent.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hinge arrangement SAHR is provided, comprises headrest front cover body and headrest rear cover body, described headrest front cover body and headrest rear cover body middle upper portion are furnished with the hinge ejection system; Hinge ejection system below is provided with the strut fixation activation system; Be provided with the Teethed bolt lock locking system between described hinge ejection system and the strut fixation activation system; Described strut fixation activation system is made up of pole and drag-line; Described drag-line is between back of seat and hinge ejection system; Described strut fixation is on cushion frame; Described Teethed bolt lock locking system is made up of stationary rack and movable tooth bar.
Described headrest front cover body is made up of the energy absorption capacity material.
Beneficial effect
The present invention relates to a kind of hinge arrangement SAHR; by between headrest front cover body and headrest rear cover body, hinge ejection system, strut fixation activation system and Teethed bolt lock locking system being set; make when manned vehicle bumps; SAHR can rise headrest moment and leans forward for the protection head; distance between the moment of collision reduces occupant's head and rests the head on; thereby reduce the corner of occupant's head greatly, reduce or elimination occupant neck whiplash injury.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1 to Figure 3, the present invention is a kind of hinge arrangement SAHR, comprises headrest front cover body 1 and headrest rear cover body 2, and described headrest front cover body 1 and headrest rear cover body 2 middle upper portion are furnished with hinge ejection system 4; Hinge ejection system 4 belows are provided with strut fixation activation system 3; Be provided with Teethed bolt lock locking system 5 between described hinge ejection system 4 and the strut fixation activation system 3; Described strut fixation activation system 3 is made up of pole and drag-line; Described drag-line is between back of seat and hinge ejection system; Described strut fixation is on cushion frame; Described Teethed bolt lock locking system 5 is made up of stationary rack and movable tooth bar; Do not have to damage and to automatically reset under the effect at retracing spring if described hinge ejection system 4 strut fixation activation systems, 3 tooth bars and latch system 5 finish the back in collision; Described headrest front cover body 1 is made up of the energy absorption capacity material.
When manned vehicle bumps, the mechanism of occupant back on hip point rotation triggering backrest, drag-line in the pulling strut fixation activation system, activate hinge ejection system 4, promoting headrest front cover body 1 separates with headrest rear cover body 2, headrest 1 moment of front cover body is risen and lean forward the distance between the moment of collision reduces occupant's head and rests the head on; Optional position in headrest front cover body 1 operational process, as long as when being subjected to impulsive force from occupant's head, the movable tooth bar of Teethed bolt lock locking system 5 and stationary rack interlock locking stop occupant's head no constrained motion backward.SAHR enters mode of operation, occupant's head is held and absorbs a part of impact energy, effectively reduces or eliminates occupant's neck whiplash injury.
