Abstract
The utility model relates to an active mode headrest with a hinge structure, which comprises a headrest front cover body and a headrest rear cover body, wherein a hinge push-out system is arranged at the middle upper parts of the headrest front cover body and the headrest rear cover body; a supporting rod fixing and activating system is arranged below the hinge push-out system; a gear rack locking system is arranged between the hinge push-out system and the supporting rod fixing and activating system; the supporting rod fixing and activating system comprises a supporting rod and a guy cable; the guy cable is positioned between a back rest and the hinge push-out system; the supporting rod is fixed on the seat framework; the gear rack locking system comprises a fixed gear rack and a movable gear rack; and the headrest front cover body is made of energy absorption materials. The utility model ensures that when a passenger car crashes, the active mode headrest can rise up and lean forward so as to protect a head and reduce the distance between the head of a passenger and the headrest at the moment of collision. Therefore, the rotor angle of the head of the passenger can be reduced greatly, and lash injuries to the neck part of the passenger can be reduced or eliminated.
Description
Technical field
The utility model belongs to manned vehicle headrest technical field, particularly relates 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 receive bigger injury.The protection of headrest passive security exists weak point to be: at first, headrest has certain distance with occupant's head, when receiving impact, can not when head has just begun to move, play protective action; Secondly, headrest is fixed on the seat, and the strength of when head touches headrest, quickening is also very big, can not in time play protective action.
Summary of the invention
The utility model technical matters to be solved 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 utility model solves the technical scheme that its technical matters adopted: a kind of hinge arrangement SAHR is provided, comprises headrest front cover body and headrest rear cover body, described headrest front cover body is furnished with the hinge ejection system with headrest rear cover body middle upper portion; 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 utility model relates to a kind of hinge arrangement SAHR; Through 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 that when manned vehicle bumps SAHR can rise headrest moment and leans forward the distance between the moment of collision reduces occupant's head and rests the head on for the protection head; 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 utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
To shown in Figure 3, the utility model is a kind of hinge arrangement SAHR like Fig. 1, comprises headrest front cover body 1 and headrest rear cover body 2, and described headrest front cover body 1 is furnished with hinge ejection system 4 with headrest rear cover body 2 middle upper portion; 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 finish the back with Teethed bolt lock locking system 5 in collision; Described headrest front cover body 1 is made up of the energy absorption capacity material.
When manned vehicle bumps; The mechanism on the backrest is triggered around the rotation of hip point in the occupant back; Drag-line in the pulling strut fixation activation system activates hinge ejection system 4, promotes headrest front cover body 1 and 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 receiving impulsive force from occupant's head, the movable tooth bar of Teethed bolt lock locking system 5 and stationary rack interlock locking, the no constrained motion backward of prevention occupant's head.SAHR gets into mode of operation, and occupant's head is held and absorbed a part of impact energy, effectively reduces or eliminates occupant's neck whiplash injury.
