ABSTRACT:
A suspension seat for an automotive vehicle includes a seat frame which is vertically movably supported on a parallel link mechanism having front and rear links. A compression spring and a shock absorber are coaxially combined and installed between an upper and back side portion of the seat frame and an arm portion connected to the rear link. Therefore, the suspension seat sufficiently absorbs an impact force while keeping small a space between the seat and the floor.
