Turnover seat of railway passenger vehicle

Abstract

The invention relates to a seat of a railway passenger vehicle, in particular to a turnover seat of the railway passenger vehicle. The turnover seat comprises a seat body and a backrest, wherein connecting metal sheets are arranged at the two sides of the backrest; an arc-shaped slide groove is formed in each connecting metal sheet; the seat body is movably connected with the slide grooves by rotary shafts; the rotary shafts are moved in the slide grooves, so as to turn over the seat; a locking mechanism is arranged in the connecting metal sheet at one side, so as to effectively lock the seat in the folding or unfolding state. The turnover seat has the advantages that in the crowd peak period, the seat is folded and locked, the space is saved, and the passenger capacity is improved; in the crowd valley period, the seat is unfolded for the passenger to use.

Description

technical field [0001] The invention relates to a seat for a rail passenger car, in particular to a reversible seat for a rail passenger car. Background technique [0002] At present, major cities in China are developing rail transit in order to solve the current traffic jams encountered in the city, because the transportation capacity and speed of rail transit have been greatly improved compared with automobiles, and the interior volume of existing rail passenger cars is fixed, and subways and light rail seats The chairs are basically fixed seats and manual folding seats, which occupy a large area in the compartment, and the number of passengers in the compartment is limited by the seats, which makes it impossible to carry more passengers during the peak hours of commuting and commuting. Or the unfolded state is controlled by passengers, and space cannot be vacated during the peak period of the flow of people, and the passenger capacity is low. [0003] Chinese patent (CN2...

AI Technical Summary

Problems solved by technology

[0002] At present, major cities in China are developing rail transit in order to solve the current traffic jams encountered in the city, because the transportation capacity and speed of rail transit have been greatly improved compared with automobiles, and the interior volume of existing rail passenger cars is fixed, and subways and light rail seats The chairs are basically fixed seats and manual folding seats, which occupy a large area in the compartment, and the number of passengers in the compartment is limited by the seats, which makes it impossible to carry more passengers during the peak hours of commuting and commuting. Or the unfolded state is controlled by passengers, and no space can be vacated during the peak flow of people, and the passenger capacity is low

[0003] Chinese patent (CN202541353U) discloses a folding seat, which can be folded by connecting the seat surface and the backrest through the connection of the connecting shaft and the torsion spring, but the seat cannot be locked by the driver, so it is only suitable for small vehicles

Therefore, there has never been a seat suitable for railway vehicles with high passenger capacity, flexible combination and locking.
