ABSTRACT:
A vehicle seat assembly is provided having a inflatable bag positioned within its seat cushion. The bag comprises first and second fabric members joined by a rib fabric member. Each first and second member is a laminate consisting of a meshed middle fabric sandwiched between two thermoplastic resin layers adhered to one another via the meshes. Only the outer peripheries of the two resin layers are in direct sealing contact with one another. An air port is sealingly connected to the first or second member to allow air to be supplied or removed from the bag to change its contour.
