Decorative panel with invisible tear seam

Claim 2

A composite decorative panel cover for a vehicle interior having a predetermined hidden tear seam line overlying an air bag that is inflated in response to vehicle impact comprising: a rigid inner layer having discrete unconnected surfaces abutting each other along said seam line, said rigid inner layer formed by first and second separate members, each of said separate members having side portions, said cover including a flexible outer layer performed and separate from said rigid inner layer; said flexible outer layer having a weakened section along said seam line created by a depression on its inner surface, said depression directly overlying said discrete unconnected surfaces of said rigid inner layer; an intermediate layer of resilient foam having discrete unconnected surfaces abutting each other along said seam line and completely filling the void between the inner and outer layers to completely support said outer layer to render said seam line invisible, said unconnected surfaces of said intermediate layer of resilient foam being directly aligned with said discrete unconnected surfaces of said rigid inner layer and also being directly aligned with said depression; whereby said discrete unconnected surfaces of said rigid inner liner and said intermediate layer of resilient foam material will separate without breakage to apply a force against said depression to cause said cover to separate and form an opening for deployment of the airbag therethrough.

Claim 3

Claim 4

A decorative panel cover for an air bag which is located in a storage compartment in a vehicle interior for deployment outwardly of the panel upon inflation upon inflation, the cover having a predetermined hidden tear seam line comprising: said cover having a U-shaped hidden tear seam line partially framing a deployment opening in said cover; a rigid inner support layer having discrete unconnected surfaces abutting each other along said U-shaped hidden tear seam line, said rigid inner layer formed by first and second separate members, each of said separate members having side portions, said cover including a flexible outer skin layer performed and separate from said rigid inner layer presenting a smooth outer surface and having a weakened section along said seam line on its inner surface, said weakened section directly aligned with said discrete unconnected surfaces of said rigid inner layer; an intermediate resilient foam layer having discrete unconnected surfaces abutting each other along said seam line, said discrete unconnected surfaces of said intermediate resilient foam layer being directly aligned with said discrete unconnected surfaces of said rigid inner layer and said weakened section also being directly aligned with said discrete unconnected surfaces of said intermediate resilient foam layer, whereby inflation of the air bag tears the outer skin along the seam line to pivot the door open about a hinge line extending between the ends of the seam line to enable deployment of the air bag outwardly of the panel and whereby said discrete unconnected surfaces of said rigid inner liner and said discrete unconnected surfaces of said intermediate layer of resilient foam material will separate without breakage to apply a force against said weakened section to cause said cover to separate and form an opening for deployment of the airbag therethrough.

Claim 5

The panel of claim 2, wherein the foam layer is configured to completely fill the void between the inner and outer layers to fully support the outer skin and prevent sagging thereof along said seam line to preserve its invisibility.

Claim 6

The panel of claim 2, wherein the intermediate resilient layer is formed of olefin foam or polyurethane foam.

Claim 7

The panel of claim 2, wherein the inner support layer is formed of a rigid thermoplastic material.

Claim 8

The panel of claim 2, wherein the flexible outer skin is vinyl.

Claim 9

A decorative panel cover for an air bag which is located in a storage compartment in a vehicle interior for deployment outwardly of the panel upon inflation, the cover having a predetermined hidden tear seam line and comprising: said cover having a H-shaped hidden tear seam line partially framing a deployment opening in said cover and defining a pair of mating doors in the cover; a rigid inner support layer having discrete unconnected surfaces abutting each other along said H-shaped hidden tear seam line, said rigid inner layer formed by first and second separate members, each of said separate members having side portions, said cover including a flexible outer skin layer preformed and separate from said rigid inner layer presenting a smooth outer surface and having a weakened section along said seam line on its inner surface, said weakened section directly overlying said discrete unconnected surfaces of said rigid inner layer; an intermediate resilient foam layer having discrete unconnected surfaces abutting each other along said seam line, said unconnected surfaces of said intermediate resilient foam layer being directly aligned with said discrete unconnected surfaces of said rigid inner layer and said weakened section also being directly aligned with said discrete unconnected surfaces of said intermediate resilient foam layer, whereby inflation of the air bag tears the outer skin along the seam line to pivot the doors open about a hinge line extending between the ends of the seam line to enable deployment of the air bag outwardly of the panel and whereby said discrete unconnected surfaces of said rigid inner liner and said discrete unconnected surfaces of said intermediate layer of resilient foam material will separate without breakage to apply a force against said weakened section to cause said cover to separate and form an opening for deployment of the airbag therethrough.

Claim 10

A decorative panel cover for an air bag which is located in a storage compartment in a vehicle interior for deployment outwardly of the panel upon inflation, the cover having a predetermined hidden tear seam line and comprising: said cover having a H-shaped hidden tear seam line partially framing a deployment opening in said cover and defining a pair of mating doors in the cover; a rigid inner support layer having discrete unconnected surfaces abutting each other along said H-shaped hidden tear seam line, said rigid inner layer formed by first and second separate members, each of said separate members having side portions, said cover including a flexible outer skin layer preformed and separate from said rigid inner layer presenting a smooth outer surface and having a weakened section along said seam line on its inner surface, said weakened section directly overlying said discrete unconnected surfaces of said rigid inner layer; an intermediate resilient foam layer having discrete unconnected surfaces abutting each other along said seam line, said unconnected surfaces of said intermediate resilient foam layer being directly aligned with said discrete unconnected surfaces of said rigid inner layer and said weakened section also being directly aligned with said discrete unconnected surfaces of said intermediate resilient foam layer, whereby inflation of the air bag tears the outer skin along the seam line to pivot the doors open about a hinge line extending between the ends of the seam line to enable deployment of the air bag outwardly of the panel and whereby said discrete unconnected surfaces of said rigid inner liner and said discrete unconnected surfaces of said intermediate layer of resilient foam material will separate without breakage to apply a force against said weakened section to cause said cover to separate and form an opening for deployment of the airbag therethrough.

Claim 11

The panel of claim 7, wherein the foam layer is configured to completely fill the void between the inner and outer layers to fully support the outer skin and prevent sagging thereof along said seam line to preserve its invisibility.

Claim 12

The panel of claim 7, wherein the intermediate resilient layer is formed of olefin foam or polyurethane foam.

Claim 13

The panel of claim 7, wherein the inner support layer is formed of a rigid thermoplastic material.
