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.

Process for forming an elastomeric membrane

Elastomeric membrane and its method of manufacture

A high strength, room temperature curable epoxy tooling compositions containing interstitially-matched filler systems for making cast-to-size forming tools for metal sheet stamping. The composition can be fully cured by at least one aliphatic amine catalyst in twelve hours producing a rigid article having a tensile strength of at least 40 MPa and a compressive strength of at least 100 MPa.

High strength epoxy tooling compositions

A thermoplastic blend of polyethylene terephthalate, a polyester elastomer, and an aromatic phosphite. The polyblend has greatly improved impact strength.

High impact polyethylene terephthalate polyblends

Vehicle seat suspension component and its method of manufacture

A high impact thermoplastic polyblend of a polyethylene terephthalate, a polyester elastomer, and an aromatic phosphite. The aromatic phosphite when added in amounts up to as much as about 5 percent by weight of the total polyblend composition causing grafting of the polyester elastomer onto the polyethylene terephthalate chains producing a thermoplastic polyblend composition having superior impact strength.
