Abstract

A resiliently-mounted vehicle seat is provided with means for adjusting its height. The seat is of the kind having a seat frame supported from an underframe by scissors linkages. A link of each scissor linkage has an extension piece which is engaged by a spring and damping unit. The extension piece is pivotable about a pivot about which the associated link also pivots. The extension piece is releasably securable to the link through an intermediate link. The arrangement affords an adjustment mechanism which gives fine adjustment of the height while not affecting the installation height of the seat.
