Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a reversible seat based on a rail vehicle. Background Art

[0002] As we all know, the existing rail vehicle seats are the main components for passengers to sit in rail transit vehicles. The design and layout of the seats directly affect the passengers' riding comfort and the space utilization of the vehicle. Since rail vehicles, especially public transportation such as subways, need to operate in underground confined spaces and have a large passenger flow, the seats also need to consider factors such as fire safety and easy cleaning.

[0003] Existing rail vehicle-based seats are often fixed in one direction when in use and cannot be flexibly adjusted according to passenger needs or changes in the car layout. This not only limits the passenger experience, but also affects the rational use of the car space, resulting in high limitations in its use. For this reason, we propose a reversible seat based on rail vehicles. Utility Model Content
