Abstract
A suspension system for a seat of a vehicle comprises a base, a linkage, and a seat attached to the base via the linkage. A pneumatic shock absorber provides a respective resistance level against movement of the seat with respect to the base based on a corresponding pressure level of air or gas within the pneumatic shock absorber. An output member of a linear motor is connected to the seat via a bracket. A first sensor is arranged to detect first sensor data associated with an instantaneous position of the seat versus time. A controller generates at least one of a first control signal for the linear motor to change a height of the seat in opposition to a change in the instantaneous position of the seat and a second control signal to change the pressure level.
