At the working position, the car flip seat is plugged into the socket through the plug of the webbing provided thereon. With this technical solution, the plugging of the webbing plug on the car seat and the socket is facilitated by the fixed bracket provided on the side panel metal of the car and the socket rotatably connected to the fixed bracket. Compared with the solution in the prior art of inserting the webbing into the ceiling armrest, the working efficiency is improved and the reliability of the suspension is guaranteed.

[0004] Some existing car seats are installed on both sides of the interior of the car compartment, such as some seats of some ambulances or explosion-proof vehicles are installed on both sides of the interior of the car compartment.
