The specific embodiment
In embodiment as shown in the figure, the body part of headrest does not show that automotive seat do not show yet, but are appreciated that in conjunction with explanation described later the part that does not have to show can adopt existing products to constitute.And embodiment described later adopts modular design, and cost is lower, and the assembling mode is simple, is fit to various automotive seat and installs.
As shown in Figure 6, the crash-active device comprises cover plate 1, drag-line support 2, drag-line 3, slide rail 4, headrest conduit 5, adapter plate 6, latch hook 7, operating spring 8, sliding panel 9, locking pin 10, latch hook spring 11.
Can be simultaneously referring to figs. 1 through Fig. 6, cover plate 1 is captiveed joint with adapter plate 6, and remaining assembly or member are built between cover plate 1 and the adapter plate 6 basically.Adapter plate 6 and cover plate 1 are formed fixed body, are arranged on regularly on the backrest of automotive seat.The both sides welding headrest conduit 5 of sliding panel 9, and connect slide rail 4, slide rail 4 is Plastic Parts, corresponding slide rail 4, and there is chute 60 both sides of adapter plate 6.Slide rail 4 and chute 60 bearing fits are so that sliding panel 9 can slide up and down at adapter plate 6.Sliding panel 9, slide rail 4, headrest conduit 5 constitute slide mass.Headrest conduit 5 connects head rest body, and head rest body comprises the expanded material of support passengers head.
One end of operating spring 8 is connected and fixed plate 6, the other end connects sliding panel 9, under confined state, the 8 flexible distortion of two operating springs, producing has spring force, makes sliding panel 9 relative fixed plates 6 that the trend of upwards sliding be arranged, but owing to the cooperation by latch hook 7 and locking pin 10, sliding panel 9 is hidden in the fixed body, under the state that the crash-active device is not triggered as depicted in figs. 1 and 2.And in a single day be triggered, operating spring 8 will drive sliding panel 9 upward movements, so that the head rest body upward movement, as shown in Figure 3 and Figure 4, the conduit 5 of resting the head on this moment exposes fixed body.
Latch hook 7 is rotatably connected to the middle part of adapter plate 6 by pivot, and it is equipped with latch hook spring 11, and latch hook spring 11 can make latch hook 7 reset.Latch hook 7 is connected with an end of drag-line 3, and drag-line 3 is fixed on the drag-line support 2, and drag-line support 2 is installed in the backrest.The moving down of drag-line 3 can drive latch hook 7 and clockwise rotate, and as shown in Figure 5, thereby breaks away from locking pin 10; in case locking pin 10 has not had the constraint of latch hook 7; slide mass is upward movement on fixed body just, drives the head rest body upward movement, thereby plays the effect of protection passenger neck.
Therefore; when the rear impact of automobile takes place; passenger's body is moved backward with the backrest expanded material of automotive seat; run into drag-line 3, drag-line 3 pulling latch hooks 7, latch hook 7 rotates; under the effect of operating spring 8; slide mass is along chute 60 upward movements of adapter plate 6, thereby plays the support passengers head, the effect of protection cervical vertebra.
