ABSTRACT:
A flame-resistant cushion includes a frame, an inner core of foamed polyurethane material carried by the frame, and an exterior layer of foamed neoprene bonded to and completely covering the entire surface area of the top, front, back and both sides of the core material. A metal pan is also secured to the seat frame to enclose the bottom of the cushion. In making the cushion, a latex water emulsion of neoprene is foamed and deposited in a thin layer on a carrier sheet. This composite lines a mold with the foam side engaging the mold; and unreacted polyurethane foam is poured into the mold. The adhesive properties of the polyurethane cause it to bond to the carrier sheet as it gels forming an integral cushion material with a covering of neoprene for greater fire resistance.
