Vehicle seat suspension system
First Claim
1. A suspension system for a seat for a vehicle, said seat having a front portion and a rear portion comprising:
- a base frame adapted to be rigidly attached to said vehicle;
a seat support frame adapted to be attached to said seat and having a front portion and a rear portion and a right side and a left side;
pivot means connected to said seat support frame for allowing said seat support frame to pivotally move with respect to said base frame, said pivot means comprising a ball and socket linkage between said base frame and said seat support frame;
spring means connected between said base frame and said seat support frame for limiting said pivotal movement of said seat support frame; and
shock absorber means adapted to be connected between said base frame and said rear portion of said seat for dissipating energy absorbed by said spring means,whereby said pivotal movement of said seat support frame may be around two different axes of rotation.

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.
