Patent ID: 7669823

Claim:
A vehicle seat suspension apparatus, comprising: a base; a stationary swivel housing and a rotational swivel housing together forming a pedestal supported by the base; a seat supporting platform; a suspension mechanism connecting the pedestal and the platform; an hydraulic shock absorber having a non-rotational cylinder connected to either the base or the stationary housing and a piston extending upwardly from the cylinder through the rotational housing and connecting to the suspension mechanism; a spring connected to the seat suspension mechanism; and a gimbal mounting device connecting the hydraulic shock absorber to the base or stationary swivel housing, thereby permitting inclination of the actuator as the suspension mechanism or seat supporting platform moves; wherein the seat supporting platform, suspension mechanism, and spring are able to rotate through 360 degrees while the base, stationary swivel housing and shock absorber cylinder remain rotationally fixed, and a gimbal mounting device to connect the hydraulic shock absorber to the base or stationary swivel housing, thereby permitting inclination of the actuator as the suspension mechanism or seat supporting platform moves.
