Description
Technical field
The present invention relates to automotive seat, especially relating to a kind of auto against active safe headrest device with letting out force mechanisms.
Background technology
The active safety pillow that current automotive seat are installed is popularized at automobile manufacturing field gradually as standard configuration.When vehicle suffers from rear-end impact or emergency brake; for keeping the driver correctly taking attitude; the head that active headrest moves after can supporting acceleration timely and effectively; the shearing force that the acceleration/accel obviously alleviating collision or emergency brake moment produces for neck collar; cervical vertebra for occupant serves protective effect, can reduce knock into the back shock or the injury to driver's cervical vertebra that brings of emergency brake.But current active headrest cost of development is higher, can continue to use once need to re-start replacing after triggering, maintenance cost is high.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, safety and stability and can self-return with the auto against active safe headrest device letting out force mechanisms.
For achieving the above object, the present invention can take following technical proposals:
Auto against active safe headrest device with letting out force mechanisms of the present invention, comprise seat back-rest framework A and be arranged on the head pillow frame B above described seat back-rest framework, the backrest side plate of described seat back-rest framework both sides is symmetrically arranged with support clamp, described support clamp offers jack, the U-shaped frizzen two ends be horizontally set in the middle part of described seat back-rest framework are actively plugged in described jack, be respectively arranged with returning spring at described U-shaped frizzen two ends, the other end of described returning spring is connected with described backrest side plate; The middle part hinge of described U-shaped frizzen has the interlock plate upwards extended, and is fixed with headrest support in the upper end of described interlock plate, and described headrest support level is by being placed on the pipe support on seat back-rest framework top; Described headrest support is arranged at intervals with guide pin bushing, and the pipe link of described head pillow frame B fixedly inserts in described guide pin bushing; Be hinged with damp hinge in headrest support between two guide pin bushings, the round end of described damp hinge rearward extends to the top of described pipe support.
Described interlock plate is vertically arranged with brace rod.
The invention has the advantages that structure is simple, light, safety and stability, production maintenance is with low cost.Under normal circumstances, inside the sponge of U-shaped frizzen and back of seat, be in fit-state always, take up room little, be conducive to the layout design of other functional components.When vehicle runs into rear-end impact or emergency brake, U-shaped frizzen can drive head pillow frame forward, supports human body head timely and effectively, alleviates the shearing force produced instantaneously neck, plays actv. protective effect to occupant's cervical vertebra.Frizzen both sides are provided with returning spring, and after collision or emergency brake terminate, frizzen can rotate forward and get back to original position under the pulling force effect of returning spring.In rear-end impact or emergency brake, the damp hinge that headrest support inside is installed lets out force mechanisms as one, after ensureing the timely support human body head of headrest, can also rotate backward under the condition of certain bearing force, and in rotary course, counteract a part of head application force, further reduce the acceleration/accel of head, thus decrease collide or emergency brake time the shearing force of human body neck is damaged, make the risk of neck site tissue damage reduce 50%.

Detailed description of the invention
As Figure 1-4, auto against active safe headrest device with letting out force mechanisms of the present invention, comprise seat back-rest framework A and be arranged on the head pillow frame B above seat back-rest framework, the backrest side plate 1 of seat back-rest framework both sides is symmetrically arranged with and supports clamp 2, support on clamp 2 and offer jack, U-shaped frizzen 3 two ends be horizontally set in the middle part of seat back-rest framework are actively plugged in jack, be respectively arranged with returning spring 4 at U-shaped frizzen 3 two ends, the other end of returning spring 4 is connected with backrest side plate 1; The middle part hinge of U-shaped frizzen 3 has the interlock plate 5 upwards extended, and is fixed with headrest support 6 in the upper end of interlock plate 5, and headrest support 6 level is by being placed on the pipe support 7 on seat back-rest framework top; Headrest support 6 is arranged at intervals with guide pin bushing 8, and the pipe link 9 of head pillow frame B fixedly inserts in guide pin bushing 8; Be hinged with damp hinge 10 in headrest support 6 between two guide pin bushings 8, the round end of damp hinge 10 rearward extends to the top of pipe support 7; Interlock plate 5 is vertically arranged with brace rod 11.
In the present invention, U-shaped frizzen 3 and support clamp 2(offer jack thereon) constitute trigger mechanism, its height and position, below the headrest protection steel wire of automotive seat, is triggered by human body backrest and drives whole mechanism to rotate;
U-shaped frizzen 3 two ends are provided with fixed plate, the other end of the returning spring 4 that one end is connected with backrest side plate 1 and fixed plate are linked, constitute response agency, the pulling force of returning spring 4 can ensure the fit-state of frizzen and backrest sponge inner surface, ensure that sensitivity when the present invention needs action;
The lower end of interlock plate 5 is hinged mutually with the middle part of U-shaped frizzen 3, top and headrest support 6 weld together, drives headrest support 6 to rotate, constitute interlinked mechanism while frizzen 3 is rotated;
Damp hinge 10 fixed end is hinged in headrest support 6, and round end rearward extends to the top of pipe support 7, is namely overlapped on backrest pipe support, forms and lets out force mechanisms, as shown in Figure 3.It is very simply ingenious that this lets out force mechanisms, but effect is very good.
Operating principle of the present invention is as follows:
When normal vehicle operation or when stopping, headrest is in normal operating condition (rearmost end of headrest front and back position), keeps suitable service range with human body head; Collide or emergency brake time, the relative position of human body and seat changes, react for the backward impact of human body back, now human body back can activate for the extruding of backrest the U-shaped frizzen 3 hidden in backrest, U-shaped frizzen 3 rotates, drive interlock plate 5, headrest support 6 rotate simultaneously, finally make the head pillow frame B be arranged on headrest pipe link 9 hold human body head forward, thus the impact reducing collision or emergency brake generation bring the damage to human body neck neck portion; Simultaneously when collision or emergency brake, the damp hinge 10 that headrest support 6 inside is installed is under the condition ensureing the timely support human body head of headrest, produce the rotation backward of certain speed, damp hinge 10 further reduces the acceleration/accel of head in the process rotated, counteract a part of application force, thus the twisting resistance decreased when collision or emergency brake for human body neck damages.After collision or emergency brake terminate, U-shaped frizzen 3 can rotate forward and get back to original position under the pulling force effect of returning spring 4.
The foregoing is only a kind of embodiment of the present invention, the structure that embodiment provides is not construed as limiting the invention, and the various adjustment carried out within the scope of this as required, improvement, distortion, equivalent replacement etc., all in this patent protection domain.
