ABSTRACT:
In accordance with a preferred embodiment, a dielectrically embossed automotive seat cover assembly is formed by providing a laminate of a decorative cover material, a first, relatively thin, polyurethane foam layer that is dielectrically heatable and a second thicker polyurethane foam layer that is not dielectrically heatable, and thereafter impressing a desired embossment pattern into the upper polyurethane and dielectrically fusing said upper layer of polyurethane to bond the cover layer to the lower polyurethane layer, thus forming the embossed pattern in the laminate structure.
