The invention relates to a rail transit seat which comprises a base and a backrest. A seat cushion framework and an armrest framework are fixedly arranged on the base; a backrest framework is fixedly arranged at the bottom of the backrest; the backrest framework is hinged with the seat cushion framework; an elastic positioning device is assembled at the bottom of the base, one side of the elastic positioning device is hinged to the backrest framework, and the other side of the elastic positioning device is hinged to the base. The seat is simple in structure, the seat scheme is combined with ergonomics, the rotation mode of a traditional seat backrest is improved, the backrest framework and the seat cushion framework are hinged to the H point of the rotation center of the human body, and therefore when the seat is unfolded, the rotation point of the backrest can coincide with the H point of the rotation center all the time. By means of the rotating mode, when the angle of the backrest is changed, the back is more attached to the contact face of the backrest, the supporting area is increased, the pulling and squeezing feeling is reduced, and the riding experience of passengers is improved.

    本发明涉及一种轨道交通座椅,包括底座和靠背;底座上固设有座垫骨架和扶手骨架;靠背底部固设有靠背骨架;靠背骨架与座垫骨架相互铰接;底座的底部装配有弹性定位装置,弹性定位装置一侧与靠背骨架相铰接,另一侧铰接于底座上;本发明结构简单,该座椅方案结合人体工学,改进了传统座椅靠背的旋转方式,使靠背骨架与座垫骨架铰接于人体旋转中心的H点处,这样座椅展开时靠背的旋转点将始终与旋转中心H点重合。该旋转方式会在改变靠背角度时使背部与靠背接触面更加贴合,提高支撑面积,降低拉扯和挤压感,提高乘客的乘坐体验。
