ABSTRACT:
In a sprung vehicle seat including a gas spring arrangement disposed between a seat carrier frame and a base frame, the gas spring arrangement includes a valve assembly for adjusting the pressure in a gas spring in response to the weight of the seat occupant (weight adjustment) and in dependence on the desired seat height (height adjustment). The valve assembly has a first valve means for weight adjustment and a second valve means for height adjustment, being separate from and manually operable independently of the first valve means. For weight adjustment, the seat also includes an actuator connected to the seat carrier frame and actuable for controlling the pressure in the gas spring, in dependence on the height of the seat carrier frame. A coupling means operatively connects the actuator to the seat carrier frame selectively at a plurality of different operative positions.
