[0002] The driver seats of existing urban rail transit vehicles are mostly fixed-mounted and built-in folding seats. The fixed-mounted driver seats occupy a large space, hindering the passage of drivers or maintenance personnel. Such seats are mostly used in manned subway vehicles; the built-in folding seats are hidden in the driver's desk through telescopic and folding mechanisms. There are many operating steps and difficult operation procedures when taking them out. When an emergency occurs in the vehicle, the driver or operator cannot take out the seat in time. According to investigations, some subway operators dismantle the driver's seats and abandon them. Therefore, there is an urgent need to develop a driver's seat that is easy to operate and easy to take out. Utility Model Content

[0015] The whole device comprises a flip backrest 1, a rotating shaft bracket 2, a backrest rotating shaft 3, a seat cushion 4, a reinforcing plate 5, a seat leg 6, an adjustment pressing lock 7, a mounting base 8, a limit stop hook 9, an installation positioning edge 10, and a positioning hook 11. DETAILED DESCRIPTION

[0016] When the seat is not in use, it is placed under the driver's platform. When in use, the seat can be taken out and placed in the driver's cabin. The seat cushion 4 and the flip backrest 1 are assembled modularly using mature components. The lower end is connected to the mounting base 8 through a 6061 aluminum alloy seat leg 6. The mounting base 8 is fixedly installed on the floor under the driver's platform. The seat is designed with a mounting base 8, an adjustment clamping lock 7, a seat leg 6, a seat cushion 4 and a flip backrest 1. The upper panel of the mounting base 8 is designed with an adjustment clamping lock 7 and a limit device for storing the seat; the limit device includes a limit stop hook 9 and an installation positioning edge 10. The seat leg 6 is connected to the upper part of the seat cushion 4 for supporting the seat. The seat cushion 4 is formed of a 45 cm thick foam material, a rectangular pad placed front and back and fixed on its inner frame, with an outer size of 335×350 mm, for supporting the human body. The flip backrest 1 part is formed of a 30 cm thick foam material, a rectangular pad placed upright and fixed on its inner frame, with an outer size of 335×350 mm, for supporting the human back.

[0017] The front and rear ends of the bottom of the seat legs 6 are both provided with positioning hooks 11 that can be stuck in the limit stop hooks 9.

[0018] During operation, firstly assemble the mounting base 8 and the adjusting pressing lock 7, fix the mounting base 8 on the bottom plate of the locomotive driver's platform while keeping the adjusting pressing lock 7 in the open state, and then put the assembled flip backrest 1, shaft bracket 2, backrest shaft 3, cushion 4, reinforcement plate 5, and seat leg 6 into the driver's platform along the mounting positioning edge 10 of the mounting base 8, ensure that the front positioning hook 11 of the seat leg 6 is buckled with the limit stop hook 9 of the mounting base 8, and finally lock the driver's seat with the adjusting pressing lock 7.

[0019] After actual verification, this driver's seat is easy to access and the operation is simple and easy to understand, which greatly speeds up the access speed of the driver's seat.
