Abstract
Abstract A laminated instrument panel has a door cover for concealing a supplemental inflatable restraint (SIR) system in a vehicle passenger compartment that includes a skin flap that is an integral part of the skin of the instrument panel. The skin flap is cast out of position and collapsed into the correct position when an elastomeric foam layer is foamed in place beneath the cast skin. This forms slanted grooves in the skin at the juncture of the flap and the adjacent skin of the instrument panel that have little or no gap at the surface of the skin. The skin flap can be shaped to provide a flush door or a raised door with an overlapping front edge.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
149 words
A laminated trim panel having a door cover for concealing an airbag system in a vehicle passenger compartment and a polymeric skin that includes a skin flap that is an integral part of the door cover comprising: the polymeric skin having a depending portion that contains a slanted groove for providing a weakened section or tear seam between the flap and the remaining part of the polymeric skin, a layer of energy absorbing elastomeric foam underlying the polymeric skin, and the groove being formed so that it is deep enough to provide a weakened section in the layer of energy absorbing elastomeric foam and conceals a weakened seam at the base on the groove and so that there is very little if any gap between the edge of the flap and the adjacent edge of the remaining part of the polymeric skin at the surface of the trim panel.
Claim 2
Dependent Claim
149 words
A laminated trim panel having a door cover for concealing an airbag system in a vehicle passenger compartment and a polymeric skin that includes a skin flap that is an integral part of the door cover comprising: the polymeric skin having a depending portion that contains a slanted groove for providing a weakened section or tear seam between the flap and the remaining part of the polymeric skin, a layer of energy absorbing elastomeric foam underlying the polymeric skin, and the groove being formed so that it is deep enough to provide a weakened section in the layer of energy absorbing elastomeric foam and conceals a weakened seam at the base on the groove and so that there is very little if any gap between the edge of the flap and the adjacent edge of the remaining part of the polymeric skin at the surface of the trim panel.
Claim 3
Dependent Claim
19 words
The laminated trim panel as defined in claim 1 wherein the slanted groove is formed by repositioning the flap.
Claim 4
Dependent Claim
45 words
The laminated trim panel as defined in claim 1 wherein the slanted groove is formed by repositioning the flap so that the edge of the flap engages the adjacent edge of the remaining part of the polymeric skin at the surface of the trim panel.
Claim 5
Dependent Claim
34 words
The laminated trim panel as defined in claim 1 wherein the edge of the flap engages the adjacent edge of the remaining part of the polymeric skin at the surface of the trim panel.
Claim 6
Dependent Claim
56 words
The laminated trim panel as defined in claim 1 further comprising a substrate and a door underlying the layer of energy absorbing elastomeric foam. The door being hinged to the substrate at one end and having an edge portion at an opposite end and the substrate having a ledge supporting the edge portion of the door.
Claim 7
Independent Claim
110 words
A method for making a laminated trim panel having a door cover for concealing an airbag system in a vehicle passenger compartment and a polymeric skin that includes a skin flap that is an integral part of the door cover comprising: shaping a polymeric skin so that it includes an integral skin flap that is out of position, placing the shaped polymeric skin in a mold, and foaming a layer in place beneath the polymeric skin so that the layer generated in the foaming process repositions the skin flap so that the flap has an edge that is near the adjacent edges of the remaining part of the polymeric skin.
Claim 8
Independent Claim
110 words
A method for making a laminated trim panel having a door cover for concealing an airbag system in a vehicle passenger compartment and a polymeric skin that includes a skin flap that is an integral part of the door cover comprising: shaping a polymeric skin so that it includes an integral skin flap that is out of position, placing the shaped polymeric skin in a mold, and foaming a layer in place beneath the polymeric skin so that the layer generated in the foaming process repositions the skin flap so that the flap has an edge that is near the adjacent edges of the remaining part of the polymeric skin.
Claim 9
Independent Claim
143 words
A method for making a laminated trim panel having a door cover for concealing an airbag system in a vehicle passenger compartment and a polymeric skin that includes a skin flap that is an integral part of the door cover comprising: shaping a polymeric skin so that it includes an integral skin flap that is out of position and at an angle so that the skin flap has an edge that is spaced a considerable distance from an adjacent edge of the remaining part of the polymeric skin, placing the shaped polymeric skin in a mold, and foaming an elastomeric layer in place beneath the polymeric skin so that the layer generated in the foaming process flattens the skin flap so that the edge of the skin flap is repositioned close to the adjacent edge of the remaining part of the polymeric skin.
Claim 10
Independent Claim
143 words
A method for making a laminated trim panel having a door cover for concealing an airbag system in a vehicle passenger compartment and a polymeric skin that includes a skin flap that is an integral part of the door cover comprising: shaping a polymeric skin so that it includes an integral skin flap that is out of position and at an angle so that the skin flap has an edge that is spaced a considerable distance from an adjacent edge of the remaining part of the polymeric skin, placing the shaped polymeric skin in a mold, and foaming an elastomeric layer in place beneath the polymeric skin so that the layer generated in the foaming process flattens the skin flap so that the edge of the skin flap is repositioned close to the adjacent edge of the remaining part of the polymeric skin.
Claim 11
Dependent Claim
49 words
The method for making a laminated trim panel as defined in claim 7 wherein the edge of the skin flap is connected to the adjacent edge of the remaining part of the polymeric skin by a concave membrane that is collapsed when the elastomeric layer is foamed in place.
Claim 12
Dependent Claim
40 words
The method as defined in claim 7 wherein the layer generated in the foaming process flattens the skin flap until the edge of the skin flap is supported on the adjacent edge of the remaining part of the polymeric skin.
Claim 13
Dependent Claim
41 words
The method as defined in claim 8 wherein the concave membrane is V-shaped and is collapsed until the edge of the skin flap is supported in a flush position on the adjacent edge of the remaining part of the polymeric skin.
Claim 14
Dependent Claim
65 words
The method as defined in claim 8 wherein the concave membrane has an apex and a curved leg that extends from the apex and merges smoothly with the remaining part of the polymeric skin and the concave membrane is collapsed until the edge of the skin flap is supported in an overlapping position on the adjacent edge of the remaining part of the polymeric skin.
Claim 15
Dependent Claim
18 words
The method as defined in claim 8 wherein the membrane is collapsed until it forms a slanted groove.
Claim 16
Dependent Claim
39 words
The method as defined in claim 8 wherein the membrane is collapsed until it forms a slanted groove and the edge of the skin flap is supported on the adjacent edge of the remaining part of the polymeric skin.
