Description

technical field [0001] The invention relates to a seat, in particular to a seat which can be installed on a subway or an EMU and is convenient for reversing. Background technique [0002] When the EMUs currently in operation change directions, most of them change the direction by rotating the seat, so that they are in the same direction as the train to improve ride comfort. When the seat is rotated, due to the limited space between the front and rear seats, it is very inconvenient to operate the front and rear rows at the same time every time the direction is changed. Contents of the invention [0003] In order to overcome the disadvantages of inconvenient reversing and poor comfort of existing seats, the present invention provides a reversing seat with convenient reversing and improved comfort. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A reversing seat, comprising a backrest, a transmission link, an out...
