Abstract
A suspension device for a vehicle seat has a lower frame secured to a vehicle floor, an upper frame disposed above the lower frame in parallel for mounting the vehicle seat, link plates disposed in parallel on the front side and the rear side of a vehicle for connecting the lower frame and the upper frame, torsion springs disposed near the connecting portion of the link plates for imparting elastic support force to the link plates, and a shock absorber disposed between the lower frame and the upper frame for damping the relative vibration of the above two frames.
