Abstract
A seat suspension includes a device which is responsive to a sensor which detects the condition of the road surface being traversed by the vehicle in a manner to produce relatively hard suspension characteristics when the vehicle is running on a rough road and softer characteristics when traversing a road having a smooth surface. The suspension of the vehicle if equipped with variable hardness type shock absorbers can be controlled in parallel with the seat suspension to improve the ride. Additional sensors which sense parameters such as acceleration, braking, steering angle, vehicle speed etc., can be used to control the setting of the seat suspension in addition to the basic road condition control.
