Abstract
A resiliently-mounted vehicle seat has a resilient damped mounting between the seat frame and an underframe. The mounting seeks to avoid a construction which impedes up and down movement of the seat frame and tilting of a back rest pivotally connected to said seat frame. The seat frame is supported from the underframe by a scissors linkage and the scissors linkage includes an extension of one of the links which projects beyond the pivot for that link and carries a shock absorber. A cam surface is formed by the extension and a spring is carried on a shaft movable over the cam surface. The other end of the shock absorber and of the spring are carried on shafts mounted on an extension of the seat frame or the underframe. A feature of the arrangement is the facility to adjust the spring for different occupants with minimal force.
