Cushion adjustment device for a motor-vehicle seat

摘要

There is described a device for adjusting the height of a cushion of a motor-vehicle seat (1), which comprises a parallelogram linkage (8) which can be actuated in order to change the height of the entire cushion. This parallelogram linkage (8) further includes an arm (19) adjustable in length which enables a change of the height of the front part of the cushion relative to the rear part to be obtained independently from the adjustment of the height of the entire seat. <IMAGE>
