Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
A laminated, self-supporting, automotive panel of predetermined contour consisting of an outer substrate layer of expanded polystyrene which is relatively rigid and has a substantial resistance to bending, an intermediate layer of relatively soft, compressible, flexible urethane foam bonded to one side of said substrate layer by means of an intervening layer of adhesive, said intermediate layer being of sufficient thickness to provide heat and sound insulation, to provide a soft feel and to conceal imperfections in said substrate layer, and an outer flexible decorative finish cover layer fused to the side of said intermediate layer opposite said substrate layer in direct surface-to-surface contact therewith.
Claim 2
Dependent Claim
105 words
A laminated, self-supporting, automotive panel of predetermined contour consisting of an outer substrate layer of expanded polystyrene which is relatively rigid and has a substantial resistance to bending, an intermediate layer of relatively soft, compressible, flexible urethane foam bonded to one side of said substrate layer by means of an intervening layer of adhesive, said intermediate layer being of sufficient thickness to provide heat and sound insulation, to provide a soft feel and to conceal imperfections in said substrate layer, and an outer flexible decorative finish cover layer fused to the side of said intermediate layer opposite said substrate layer in direct surface-to-surface contact therewith.
