Abstract
A suspension device for a vehicle seat, which comprises an upper frame, a lower frame, an X-shaped link interposed between the upper and lower frames, a vertically active elastic element for resiliently supporting the X-shaped link in the vertical direction, a slide frame, and a fore-and-aft active elastic element for resiliently supporting the slide frame in the forward and backward directions. The slide frame is connected with one end of the X-shaped link, so that the suspension device is not only active vertically for giving elasticity to the vertical motion of X-shaped link, but also active for allowing fore-and-aft resilient movement of the upper frame.
