Abstract

A vehicle seat assembly is for a vehicle seat having a back rest and a seat surface. The back rest is adjustable in inclination and the seat surface is adjustable in height and inclination. To reduce the height of the assembly and to enable the height and inclination of the seat surface to be adjusted independently of the back rest inclination, the seat frame is supported at its front end by levers. At the rear end of the seat frame is a support frame and a back rest frame, the back rest frame being movable relative to the support frame to raise and lower the rear end of the seat frame. The support frame and back rest frame are movable together about a horizontal axis to adjust the inclination of the back rest and the seat frame is suspended at its rear end on the back rest frame.
