Abstract:
1. A suspension system for a seat of a vehicle, the suspension system comprising: a base; a linkage; a seat attached to the base via the linkage; a pneumatic shock absorber providing 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; a plurality of cylindrical members spaced apart beneath the seat; a tension member arranged to engage the cylindrical members, wherein a generally vertical portion of the tension member is operably coupled to the seat via a bracket; an electric motor for driving one of the cylindrical members; a first sensor for detecting first sensor data associated with an instantaneous position of the seat versus time; a controller for generating at least one of a first control signal for the electric 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.
