Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 155 words
A method of making an embossed, covered, polyurethane foam cushion comprising forming a laminate comprising two polyurethane foam layers bonded to each other, the first of said layers being composed so as to be dielectrically heatable to a fusion temperature for embossing and the second of said foam layers being composed so as to not be fused by such dielectric heating, bonding a layer of covering material to said laminate overlying said first foam layer, and pressing an embossed pattern into said cover layer and the first polyurethane layer while dielectrically heating said first layer to fuse it and bond the depressed portion of the cover layer in the desired embossment pattern to the second foam layer without fusing and embossing the second foam layer, the initial thickness of said first layer being suitable to form the desired embossment, and the overall thickness of the two foam layers being sufficient to provide a desired cushion.
Claim 2
Independent Claim 155 words
A method of making an embossed, covered, polyurethane foam cushion comprising forming a laminate comprising two polyurethane foam layers bonded to each other, the first of said layers being composed so as to be dielectrically heatable to a fusion temperature for embossing and the second of said foam layers being composed so as to not be fused by such dielectric heating, bonding a layer of covering material to said laminate overlying said first foam layer, and pressing an embossed pattern into said cover layer and the first polyurethane layer while dielectrically heating said first layer to fuse it and bond the depressed portion of the cover layer in the desired embossment pattern to the second foam layer without fusing and embossing the second foam layer, the initial thickness of said first layer being suitable to form the desired embossment, and the overall thickness of the two foam layers being sufficient to provide a desired cushion.
Claim 3
Independent Claim 146 words
A method of making an embossed, covered, polyurethane foam cushion comprising forming a laminate comprising two polyurethane foam layers bonded to each other, the first of said layers being composed so as to be dielectrically heatable to a fusion temperature for embossing and the second of said foam layers being composed so as to not be fused by such dielectric heating, pressing an embossed pattern into said first polyurethane layer while dielectrically heating said first layer to fuse it and bond the depressed portion thereof in the desired embossment pattern to the second foam layer without fusing and embossing the second foam layer, the initial thickness of said first layer being suitable to form the desired embossment, and the overall thickness of the two foam layers being sufficient to provide a desired cushion, and thereafter bonding a cover material to the embossed surface of said laminate.
Claim 4
Independent Claim 146 words
A method of making an embossed, covered, polyurethane foam cushion comprising forming a laminate comprising two polyurethane foam layers bonded to each other, the first of said layers being composed so as to be dielectrically heatable to a fusion temperature for embossing and the second of said foam layers being composed so as to not be fused by such dielectric heating, pressing an embossed pattern into said first polyurethane layer while dielectrically heating said first layer to fuse it and bond the depressed portion thereof in the desired embossment pattern to the second foam layer without fusing and embossing the second foam layer, the initial thickness of said first layer being suitable to form the desired embossment, and the overall thickness of the two foam layers being sufficient to provide a desired cushion, and thereafter bonding a cover material to the embossed surface of said laminate.
Claim 5
Independent Claim 172 words
A method of making an embossed, covered, polyurethane foam automotive seat cover assembly, comprising forming a laminate comprising two polyurethane foam layers bonded to each other, the first of said layers being composed so as to be dielectrically heatable to a fusion temperature for embossing and the second of said foam layers being composed so as to not be fused by such dielectric heating, bonding a layer of covering material to said laminate overlying said first foam layer, and extending beyond said foam layer as necessary to trim an automotive seat, and pressing an embossed pattern into said cover layer and the first polyurethane layer while dielectrically heating said first layer to fuse it and bond the depressed portion of the cover layer in the desired embossment pattern to the second foam layer without fusing and embossing the second foam layer, the initial thickness of said first layer being suitable to form the desired embossment, and the overall thickness of the two foam layers being sufficient to provide a desired cover assembly.
