    • A seat for a wheelchair is provided. An exemplary embodiment of the seat includes a seat back portion, a bottom portion, and a linkage coupling the bottom portion to the seat back portion such that the seat back portion is movable relative to the bottom portion. The linkage generally includes a first link and a second link. The first link is generally pivotally connected to the bottom portion and the seat back portion. The second link is generally pivotally connected to the bottom portion and the seat back portion. The first link and the second link pivot relative to the seat back portion and the bottom portion as the seat back portion is moved relative to the bottom portion.
    • 提供轮椅座椅。 座椅的示例性实施例包括座椅靠背部分,底部部分和将底部部分联接到座椅靠背部分的连杆,使得座椅靠背部分可相对于底部部分移动。 连杆通常包括第一连杆和第二连杆。 第一连杆通常枢转地连接到底部部分和座椅靠背部分。 第二连杆通常枢转地连接到底部和座椅靠背部分。 当座椅靠背部分相对于底部部分移动时,第一连杆和第二连杆相对于座椅靠背部分和底部部分枢转。
