Abstract
A controllable fluid damper is employed in a seat suspension system. A microprocessor receives successive signals from a displacement sensor and computes a rate of displacement. This displacement rate is used to determine an appropriate control signal for the damper to provide the desired isolation of the seat occupant from the vibration input to the frame. A rate control method is disclosed as a preferred control technique for providing the desired isolation, although both the control hardware and method can be used independently.
