转换座椅
摘要：
一种座椅组件，其在车辆底板上方支撑乘客并且可收起到底板下方的凹槽内。座椅组件包括在上乘坐表面和下表面之间延伸的座垫。座椅靠背枢转地耦联至座垫，用于在乘坐位置和向前折叠倾翻而与座椅重叠的位置之间运动。升降机构在座垫的下表面和凹槽之间延伸，用于允许座椅组件在用以在底板上方支撑乘客的乘坐位置和设置在底板的凹槽内的收起位置之间选择性的运动。升降机构包括一对前腿和一对后腿，前腿具有枢转地耦联至底板中的凹槽的下端部和枢转地耦联至座垫的上端部，后腿具有枢转地耦联至底板中的凹槽的下端部和枢转地耦联至座垫的上端部。第一锁定撑杆在前腿之一和底板内的凹槽之间延伸，第二锁定撑杆在另一前腿和底板内的凹槽之间延伸。第一和第二释放手柄操作性地分别耦联至第一和第二锁定撑杆，用于独立地解锁锁定撑杆而选择性地允许升降机构将座椅组件从乘坐位置枢转至底板中的凹槽内的收起位置。
摘要（英）：

A seat assembly supports an occupant above a floor of a vehicle and is stowable within a recess below the floor. The seat assembly includes a seat cushion extending between a top seating surface and a bottom surface. A seat back is pivotally coupled to the seat cushion for movement between a seating position and a forwardly folded dump position overlying the seat cushion. A riser mechanism extends between the bottom surface of the seat cushion and the recess for allowing selective movement of the seat assembly between a seating position to support the occupant above the floor and a stowed position disposed within the recess in the floor. The riser mechanism includes a pair of front legs having a lower end pivotally coupled to the recess within the floor and an upper end pivotally coupled to the seat cushion, and a pair of rear legs having a lower end pivotally coupled to the recess within the floor and an upper end pivotally coupled to the seat cushion. A first locking strut extends between one of the front legs and the recess within the floor and a second locking strut extends between the other front leg and the recess within the floor. First and second release handles are operatively coupled to the first and second locking struts, respectively, for independently unlocking the locking struts to selectively allow the riser mechanism to pivot the seat assembly from the seating position to the stowed position within the recess in the floor.
