ABSTRACT:
In this resilient multi layered member, there are provided as laminated together: a surface skin layer, formed of PVC resin powder made into a gel, on the outside side of the resilient multi layered member; a foam material layer, formed from foamed PVC resin powder, the outer side of which is adhered to the inner side of the surface skin layer; a cushion material layer, the outer side of which is adhered to the inner side of the foam material layer; and a substantially stiff core material layer, the outer side of which is adhered to the inner side of the cushion material layer, on the inside side of the resilient multi layered member. There may be further included an adhesive layer by means of which the outer side of the cushion material layer is adhered to the inner side of the foam material layer. The cushion material layer may be formed from urethane foam, or from non woven fabric, which may be a felt material, and may have a density greater than about 200 grams per square meter. This density may more particularly be between about 260 grams per square meter and about 300 grams per square meter. Alternatively, the cushion material layer may be formed from compressed urethane material, which may be compressed by a factor of from about 50% to about 80%, and may have a density of between about 0.05 grams per cubic centimeter and about 0.10 grams per cubic centimeter.
