Abstract: A seat base, in particular for a motor vehicle seat, which may be manufactured at reasonable cost, has the necessary strength properties and permits replacement of the upholstery and/or cover is disclosed. The seat base is divided into a dish-shaped upholstery support made from a thermoplastic material and a seat frame. The seat frame is consists of at least two longitudinal supports made from a thermoplastic, high-strength which are connected to one another by means of steel cross-beams.

Abstract: In vehicle seat frames the overload protection during the deformation of the brackets (4; 5) of the fittings (3) as a result of impact stresses includes a particular force path in that a fixed point connection (20) and a sliding connection (21) are formed by connecting bolts (9; 10, 22; 26) between at least one bracket (4; 5) of each fitting (3) and the lower seat part (1) or backrest (2).

Abstract: A fastening connection between a cushion covering and a support for the cushion is disclosed. The support may be molded from a thermoplastic resin by injection. The connection comprise a hook profile strip which snaps into position fastening the edge of the cushion cover to the support. The support is characterized in that it has a U-shaped edge having recesses and projections for engaging with the hook profile strip.

Abstract: An inexpensive damper adapted to the stress frequency in the form of a shock absorber, in particular for vehicle seats, consists of an abutment (8), in which an absorber sleeve (2) of a thermoplastic material with a piston (1) guided therein with expansion bead (10) is clamped, wherein the absorber sleeve (2) is composed of a thermoplastic material having a tensile strength .sigma..sub.R of at least 40 MPa, an elongation at break .epsilon..sub.R of at least 60%, a tensile stress at yield .sigma..sub.S of at least 40 MPa and an elongation at yield .epsilon..sub.S of at least 3.5% (according to ISO/R 527 or DIN 53 455 in each case).

Abstract: In order to be able to rationalize the mass production of back rest support structures from plastic for vehicle seats by injection molding, an injection molded part is provided which comprise a back shell and a frame which surrounds it like a cassette, the frame consisting of U-section side members which are open at the side and a U-section cross member which is open on one side.

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.
