A vehicle seat assembly has a seat frame, and an integrated elastomeric filament suspension and fabric cover in which the elastomeric filaments and yarn for the fabric are knitted together and stretched over the frame to provide a low profile finished seat or back rest which functions both as a suspension and as an aesthetic trim cover.

Thin profile integrated suspension and seat trim cover

A vehicle seat suspension has a thin high strength elastomeric membrane. The membrane is formed from block copolymer material by a process in which a sheet is extruded and tensioned to orient molecules in a select direction with respect to the membrane; the oriented membrane is annealed to retain the orientation during cyclical deformation of the membrane. The sheet form membrane is adapted to be connected with respect to a vehicle seat assembly frame and to serve as a backing for foam seating material and wherein the oriented structure of the membrane provides a two stage modulus in the direction of the orientation for providing static and dynamic load support characteristics which impart passenger comfort without increasing the weight of a seat assembly.
