As shown in fig. 10, when it is necessary to switch the position of the crash cushion 32, an external force may be applied to the crash cushion 32 in the direction of the shaft-end and upward to rotate the crash cushion 32 and lift it, and finally the resting plate f is inserted into the lower resting groove h 2.
As shown in fig. 11, in the deployed state, that is, in the use state, when the upper resting groove h1 of the crash cushion 32 is restricted by the resting plate f, the crash cushion 32 protrudes out of the cavity h0 of the base 31, and the crash surface s2 of the crash cushion 32 protrudes obliquely out of the reference surface s1, and at this time, the crash surface s2 forms an angle with the reference surface s1, and the crash surface s2 serves as a force receiving surface for receiving a vehicle body crash. As shown in fig. 3, when the side flap 12 collides with the inner wall of the vehicle body, the bump stopper 32 can first collide with the inner wall of the vehicle body to perform a cushioning function.
The invention has the advantages that the bump buffering block 32 protrudes out of the cavity h0 of the base 31, and the bump surface s2 of the bump buffering block 32 obliquely protrudes out of the reference surface s 1; when the vehicle collides, the collision surface s2 of the collision buffer 32 serves as a force-receiving surface for receiving the vehicle body at the time of collision, and the energy generated by the collision is absorbed by the collision buffer 32, thereby preventing the seat main body from being directly collided with by the vehicle body.

In the process of actually applying an external force to rotate the impacted buffer block 32, as shown in fig. 10, the limiting strip g1 abuts against the longitudinal limiting plate g2, so that the impacted buffer block 32 can be prevented from moving backwards too much, the limiting strip g1 abuts against the transverse limiting plate g3, so that the impacted buffer block 32 can be prevented from lifting upwards too much, and the resting plate f can be aligned with the lower resting groove h2 more quickly, so that the quickness of state switching of the impacted buffer block 32 is improved.
When the crash cushion 32 is stored, the front end of the crash surface s2 of the crash cushion 32 is spaced apart from the front end of the cavity h0 to form a depressed region f0 above the resting plate f, and the front wall forming the depressed region f0 has an inclined surface to enlarge the caliber of the depressed region f0 for the purpose of pulling the crash cushion 32 for hand operation. And the inclination direction of the inclined plane is consistent with the partial action direction of the acting force, so that the human-computer cooperation efficiency is improved.
