Abstract
Abstract A method of producing an interior trim component using the steps of: impregnating a foam pad with a dielectrically heatable thermoplastic binder; placing the pad between a dielectrically heatable panel and decorative covering; compressing the pad; and applying an electric field to the pad and panel sufficient to heat and soften the thermoplastic binder and the panel whereby the thermoplastic binder bonds with the covering and panel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A method of producing an interior trim component comprising the steps of: providing a grooved, dielectrically heatable panel; placing a foam pad containing a dielectrically heatable thermoplastic binder atop said groove; placing a fabric atop said pad; placing a dielectrically heatable thermoplastic covering atop said fabric; overlying a first electrode atop said covering, said electrode having a knife edge mating with said groove; applying an electric field between said first electrode and a second electrode placed adjacent said panel sufficient to heat and soften said panel, said binder and said covering, said knife edge imparting a tear line on said covering; urging said pad, said fabric and said covering towards said panel within said groove, wherein said binder bonds to said panel, said fabric and said covering; and tearing said covering along said tear line.
Claim 2
Independent Claim
135 words
A method of producing an interior trim component comprising the steps of: providing a grooved, dielectrically heatable panel; placing a foam pad containing a dielectrically heatable thermoplastic binder atop said groove; placing a fabric atop said pad; placing a dielectrically heatable thermoplastic covering atop said fabric; overlying a first electrode atop said covering, said electrode having a knife edge mating with said groove; applying an electric field between said first electrode and a second electrode placed adjacent said panel sufficient to heat and soften said panel, said binder and said covering, said knife edge imparting a tear line on said covering; urging said pad, said fabric and said covering towards said panel within said groove, wherein said binder bonds to said panel, said fabric and said covering; and tearing said covering along said tear line.
