Abstract
Abstract An essentially unitary airbag cover assembly is provided for concealing an airbag module. The cover has a vehicle panel with a front surface, a foam core and panel substrate with a dropped lip or shelf on a distal end thereof. A deployment door incorporated in the panel is hinged to the panel along one side thereof with at least one of the remaining sides of the door resting in the panel on the dropped lip or shelf of the panel substrate. The deployment door and panel are substantially the same thickness, and the shelf is dropped such that when the deployment door is positioned on the dropped shelf in the panel substrate, the door and panel are on the same level and there is no need for a connection between the panel and deployment door aside from the hinged side of the door.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
260 words
An airbag cover assembly having an integral airbag deployment door incorporated in a vehicle panel for deployment of an airbag from an airbag module positioned behind said panel and deployment door, comprising: a panel front surface facing an interior of a vehicle compartment, a panel rear surface substrate, a foam core positioned between and separating said panel front surface from said panel rear surface substrate, said panel rear surface substrate having a dropped lip extending from an end thereof, a deployment door defined in said panel and hinged along one side thereon in said panel, said deployment door comprises a door front surface, a door rear surface substrate and a foam core positioned between and separating said door front surface from said door rear surface substrate and a complete discontinuity existing between the foam core of the door and the foam core of the adjacent portions of the panel and between the door rear surface substrate and the adjacent portions of the panel rear surface substrate whereby the foam core of the door is completely separated from the foam core of said panel except at the hinged side of the door, said deployment door positioned in said panel on said dropped lip of said panel rear surface substrate whereby said deployment door and adjacent portions of said panel extend side by side at the same level and whereby the deployment door can be opened without ripping any part of said foam cores, thereby preventing foam core debris from being emitted through an open deployment door on deployment of said airbag.
Claim 2
Dependent Claim
260 words
An airbag cover assembly having an integral airbag deployment door incorporated in a vehicle panel for deployment of an airbag from an airbag module positioned behind said panel and deployment door, comprising: a panel front surface facing an interior of a vehicle compartment, a panel rear surface substrate, a foam core positioned between and separating said panel front surface from said panel rear surface substrate, said panel rear surface substrate having a dropped lip extending from an end thereof, a deployment door defined in said panel and hinged along one side thereon in said panel, said deployment door comprises a door front surface, a door rear surface substrate and a foam core positioned between and separating said door front surface from said door rear surface substrate and a complete discontinuity existing between the foam core of the door and the foam core of the adjacent portions of the panel and between the door rear surface substrate and the adjacent portions of the panel rear surface substrate whereby the foam core of the door is completely separated from the foam core of said panel except at the hinged side of the door, said deployment door positioned in said panel on said dropped lip of said panel rear surface substrate whereby said deployment door and adjacent portions of said panel extend side by side at the same level and whereby the deployment door can be opened without ripping any part of said foam cores, thereby preventing foam core debris from being emitted through an open deployment door on deployment of said airbag.
Claim 3
Dependent Claim
34 words
The airbag cover assembly according to claim 1 wherein a discontinuity exists between the door front surface and the adjacent portions of the panel front surface except at the hinged side of the door.
Claim 4
Dependent Claim
246 words
An airbag cover assembly containing an integral airbag deployment door delineated in a portion of a vehicle panel for deployment of an airbag through said deployment door from an airbag module positioned behind said cover and deployment door, said panel having a front surface, a rear surface panel substrate having a distal end thereon and a foam core positioned between said front surface of said panel and said rear surface panel substrate, a dropped lip extending outwardly from said distal end of said rear surface panel substrate, hinge means mounting said airbag deployment door in said panel along one side of said deployment door with at least two remaining sides of said deployment door resting in alignment with adjacent portions of said panel on said dropped lip of said rear surface panel substrate, said deployment door comprises a door front surface, a door rear surface substrate and a foam core positioned between and separating said door front surface from said door rear surface substrate and a complete discontinuity existing between the foam core of the door and the foam core of the adjacent portions of the panel and between the door rear surface substrate and the adjacent portions of the panel rear surface substrate except at the hinged side of the door whereby the deployment door can be opened without ripping any part of said foam cores, thereby preventing foam core debris from being emitted through the open deployment door on the deployment of said airbag.
Claim 5
Dependent Claim
246 words
An airbag cover assembly containing an integral airbag deployment door delineated in a portion of a vehicle panel for deployment of an airbag through said deployment door from an airbag module positioned behind said cover and deployment door, said panel having a front surface, a rear surface panel substrate having a distal end thereon and a foam core positioned between said front surface of said panel and said rear surface panel substrate, a dropped lip extending outwardly from said distal end of said rear surface panel substrate, hinge means mounting said airbag deployment door in said panel along one side of said deployment door with at least two remaining sides of said deployment door resting in alignment with adjacent portions of said panel on said dropped lip of said rear surface panel substrate, said deployment door comprises a door front surface, a door rear surface substrate and a foam core positioned between and separating said door front surface from said door rear surface substrate and a complete discontinuity existing between the foam core of the door and the foam core of the adjacent portions of the panel and between the door rear surface substrate and the adjacent portions of the panel rear surface substrate except at the hinged side of the door whereby the deployment door can be opened without ripping any part of said foam cores, thereby preventing foam core debris from being emitted through the open deployment door on the deployment of said airbag.
Claim 6
Dependent Claim
34 words
The airbag cover assembly according to claim 3 wherein a discontinuity exists between the door front surface and the adjacent portions of the panel front surface except at the hinged side of the door.
