The invention relates to the technical field of seats, in particular to a seat cushion lifting mechanism of a seat, the seat and a vehicle. In order to solve the problems that an existing cushion lifting mechanism is inconvenient to adjust and high in cost, the seat comprises a seat basin structure, and the cushion lifting mechanism comprises a base, a driving blocking piece, an inhaul cable, a rotating support and a lifting rod; the base is fixed to the seat basin structure, the driving blocking piece is rotatably arranged on the base, the rotating support is rotatably arranged on the seat basin structure, the end of the lifting rod is connected with the rotating support, one end of the inhaul cable is connected with the driving blocking piece, and the other end of the inhaul cable is connected with the rotating support; when the driving blocking piece rotates, the rotating support is pulled to rotate through the inhaul cable so that the lifting rod can ascend and descend vertically. The inhaul cable pulls the rear portion of the seat cushion to rise by means of backward pulling force of the electric backrest, an independent driving device is omitted, the manual adjusting step of a user is omitted, the seat cushion is automatically flush with the height of the backrest, the installation cost is saved, and the adjusting efficiency of the seat cushion is improved.

    本发明涉及座椅技术领域,具体提供一种座椅的坐垫升降机构、座椅及车辆。为解决现有坐垫升降机构的调节不便以及成本较高的问题,本发明的座椅包括坐盆结构,坐垫升降机构包括基座、主动挡片、拉索、转动支架和抬升杆;基座固定在坐盆结构上,主动挡片可转动地设置在基座上,转动支架可转动地设置在坐盆结构上,抬升杆的端部与转动支架连接,拉索的一端与主动挡片连接,另一端与转动支架连接;在主动挡片转动时通过拉索拉动转动支架转动以使抬升杆上下升降。本发明拉索借助电动靠背向后倒的拉力,以拉动坐垫后部上升,省去独立的驱动装置并免去用户的手动调节步骤,坐垫自动与靠背高度齐平,节省了安装成本,提高了坐垫的调节效率。
