[0002] A bus is a commercial vehicle that can carry more than 9 people and generally has a square compartment for carrying passengers and their carry-on luggage. This type of vehicle is mainly used for public transportation and group transportation. In order to meet the bus's carrying capacity while taking into account the comfort of bus passengers, bus seats generally adopt a row design. The seats are heavy and are fixed to the floor through brackets and other fixing structures. At the same time, in order to improve the stability of the seats, the side of the seat close to the compartment wall also needs to be fixed to the compartment side wall.

[0003] At present, the fixing of passenger car seats to the side walls of the carriage generally adopts the following two fixing methods: one is the overlap type, such as Figure 1 As shown, first, a right-angle fixing piece is fixed on the side of the seat, and the horizontal plate of the right-angle fixing piece is overlapped with the supporting piece embedded on the side wall and fixed by a bolt assembly; this fixing method can overlap the horizontal plate on the supporting piece embedded on the side wall during installation, which reduces the labor workload of workers when installing the seat to a certain extent, but this fixing method requires reserving installation space for the bolt assembly, resulting in a large gap between the seat and the side wall, which does not meet the national safety standards; the other is a connection structure for the side-mounted seat feet of a bus seat as provided by Chinese utility model patent CN211223115U, in which the vertical part of the right-angle piece on the side of the seat is fixed to the embedded plate of the side wall by a bolt assembly. Although this fixing method reduces the gap between the seat and the side wall, it has the problems of inconvenient installation and positioning and high installation labor. Utility Model Content
