Abstract
A suspension system for a seat for a vehicle having a base frame rigidly attached to the vehicle. The front of a seat support frame is pivotally moveable with respect to the base frame. Springs mounted between the seat support frame and the base frame cushion the seat from forces imparted while driving the vehicle on irregular surfaces. The springs further limit the pivotal movement of the seat support frame with respect to the base frame. There are shock absorbers for dissipating energy absorbed by the springs. The pivotal movement of the seat is around two different axes of rotation, one of the axes being a horizontal axis extending across the width of the vehicle and the other axis being a longitudinal axis extending from the front to the rear of the vehicle.
