Abstract
A sprung vehicle seat comprises a fluid spring between a base frame and a seat carrier frame displaceable relative to the base frame in respect of height, together with a control means for the fluid spring. The control means includes a switching means and an actuator acting thereon, with movement in respect of height of the seat carrier frame relative to the base frame being converted into a relatively large rotary movement as between the switching means and the actuator means. The structure for converting the heightwise movement into the rotary movement includes a belt winding mechanism wherein extension and retraction of the belt in response to heightwise movement of the seat carrier frame produces the relative rotary movement, or a toothed element meshing with a gear similarly operable to provide the relative rotary movement of substantial magnitude.
