The invention provides an urban rail transit seat. The urban rail transit seat comprises a vertical plate and a seat body hinged to the vertical plate through a rotating shaft. A supporting block matched with the seat body is arranged on the vertical plate; a grooved wheel is sleeved on the rotating shaft, and a steel wire rope positioned inside the vertical plate is wound on the grooved wheel; the seat further comprises a supporting rod connected to the vertical plate through a first torsion spring shaft, the free end of the steel wire rope is wound around the first torsion spring shaft, thefree end of the supporting rod is hinged to a limiting block through a second torsion spring shaft, and a limiting groove matched with the limiting block is formed in the bottom of the seat body. In the unfolding process of the seat body, the steel wire rope drives the first torsion spring shaft to rotate in an inverse torsion mode, the supporting rod moves obliquely, the limiting block is made toform a horizontal shape under the action of the second torsion spring shaft to be clamped with the limiting groove in a matched mode, and large supporting force is achieved.

    本发明提供了一种城市轨道交通座椅,包括:立板以及通过转轴铰接立板的座椅本体;立板上设置有与座椅本体相配合的支撑块;转轴上套装有槽轮,槽轮上缠绕有位于立板内部的钢丝绳;还包括有通过第一扭簧轴连接在立板上的支撑杆,钢丝绳的自由端缠绕在第一扭簧轴上,且支撑杆的自由端通过第二扭簧轴铰接有限位块,座椅本体的底部设置有与限位块相配合的限位槽。本发明中,通过座椅本体展开过程中,钢丝绳带动第一扭簧轴逆扭力转动,使支撑杆进行斜向运动,并使限位块在第二扭簧轴的作用下形成水平状与限位槽配合卡紧,实现较大的支撑力。
