Detailed description of the invention
For further setting forth the utility model for the technological means that reaches predetermined technique object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, structure of the present utility model, feature and effect are described in detail as follows.
embodiment 1
As Fig. 2, Fig. 3, Fig. 5, Figure 6 shows that an embodiment of the present utility model, the automotive seat safety rail wider width of this embodiment, be applicable to being arranged in the middle of automobile rear seat, can also use as desk as while handrail, further expand the using function of rear row passenger.
As shown in Fig. 3, Fig. 5, Fig. 6, this safety rail specifically comprises handrail foaming 1, handrail foaming 1 is arranged on automotive seat side by fixed support 2, fixed support 2 is provided with rotating shaft 1-2, handrail foaming 1 rotates around rotating shaft 1-2 to be carried out packing up or opening, fixed support 2 is provided with collision latch ratchet 3, collision latch ratchet 3 is arranged on fixed support 2 by bearing pin 3-1, collision latch ratchet 3 is configured with retracing spring 4, and handrail foaming 1 is provided with the first block 1-3 coordinated with latch ratchet 3 of colliding.
When occurring to collide, collision latch ratchet 3 stops the first block 1-2 to move rotate predetermined angular under effect of inertia after, 1 Unscrew thus prevention handrail foams, after effect of inertia disappears, collision latch ratchet 3 removes locking under retracing spring 4 acts on, and handrail foaming 1 recovers normal rotational movement.
As shown in Fig. 3, Fig. 6, fixed support 2 is provided with the second block 2-1, when the first block 1-3 and collision latch ratchet 3 collide, the second block 2-1 provides counteracting forces for collision latch ratchet 3.
