The invention provides a railway vehicle seat which comprises a backrest and a bottom frame. The backrest comprises a connecting assembly and a first rotating matching piece; the bottom frame comprises a driving assembly connected with the connecting assembly. The railway vehicle seat further comprises two armrest seats arranged on two opposite sides of the backrest; the armrest seats are connected with the underframe, and are provided with rotating connecting pieces; the first rotating matching piece is rotationally connected with the rotating connecting pieces, so that the driving assembly pulls the connecting assembly to drive the backrest to rotate around the first rotating matching piece. Therefore, the backrest is rotationally connected with the rotating connecting pieces arranged on the armrest seats through the first rotating matching piece, so that the whole backrest can be driven to rotate when the driving assembly pulls the connecting assembly, and the adjustment of the rotating angle of the backrest is realized. When the rotating connecting pieces on the armrest seats are damaged or have fatigue failure, only the rotary connecting pieces or the armrest seats need to be replaced, and the structures of the backrest and the underframe do not need to be replaced, so that the overhauling efficiency of the backrest is improved, and the overhauling cost of the backrest is reduced.
本发明提供一种轨道车辆座椅,包括靠背和底架,靠背包括连接组件和第一转动配合件;底架包括与连接组件相连接的驱动组件;还包括设于靠背相对两侧的两个扶手座,扶手座与底架相连接;扶手座上设有转动连接件,第一转动配合件与转动连接件转动连接,以使得驱动组件拉动连接组件以带动靠背围绕第一转动配合件转动。由此,靠背通过第一转动配合件与扶手座上设置的转动连接件转动连接,以使得驱动组件拉动连接组件时可以带动靠背整体发生转动,以实现对靠背转动角度的调整,若扶手座上设置的转动连接件破损或者疲劳失效时,只需要对转动连接件或者扶手座进行更换,无需对靠背和底架的结构进行更换,提高了靠背的检修效率以及降低了靠背检修的成本。
