The invention relates to the technical field of rail transit, and discloses a double-state subway seat which comprises a carriage, a seat body is movably connected to one side of the carriage, a buffer spring is fixedly installed in the middle of the seat body, armrests are movably connected to the two sides of the seat body, rotating shafts are fixedly installed on the two sides of the seat body, one side of the seat body is movably connected with a stable supporting leg through a rotating shaft, the other side of the seat is movably connected with an inner rod through a rotating shaft, and the bottom end of the inner rod is movably sleeved with a negative pressure air chamber. By arranging the retractable seat, the seat is put down when the passenger flow volume is small, and the supporting leg is fixed and stabilized through negative pressure, so that a passenger can have a rest by putting down and fixing the seat under the condition of small passenger flow, and when the passenger flow volume is increased in the peak period of riding, the bottom plate of the compartment is pressed to open an unlocking block, so that the negative pressure in the negative pressure air chamber is damaged. At the moment, the stable supporting leg cannot be fixed, the passenger cannot conveniently choose to stand when using the seat, and therefore the containing capacity of the passenger in the compartment is improved.

    本发明涉及轨道交通技术领域,且公开了一种双状态地铁座椅,包括车厢,所述车厢的一侧活动连接有座椅,所述座椅的中间固定安装有缓冲弹簧,所述座椅的两侧活动连接有扶手,所述座椅的两侧均固定安装有转轴,所述座椅的一侧通过转轴活动连接有稳固支脚,所述座椅的另一侧通过转轴活动连接有内杆,所述内杆的底端活动套接有负压气室。本发明通过设置可收缩座椅,在客流量小时将座椅放下,并通过负压固定稳固支脚,使得小客流情况下乘客可以通过放下并固定座椅进行休息,而当乘车高峰期客流量加大时,车厢底板受压开启解锁块,使得负压气室内负压被破坏,此时稳固支脚不能被固定,乘客使用座椅不便选择站立,从而提高了车厢内乘客的容纳量。
