Abstract
Abstract A door assembly for an opening through which an inflatable restraint safety device may be deployed including a frame for supporting an inflatable restraint safety device and an opening presented in the frame, a door is disposed in the opening and is capable of rapidly moving so that the inflatable restraint device may be deployed through the opening, the door includes an impact plate portion and a foam portion bonded to the impact plate portion with the foam portion including a microcellular component having a first predetermined density and an integral outer skin component distinct from the microcellular component and formed integral with the microcellular component and which has a second predetermined density which is greater than the first predetermined density of the microcellular component for providing an aesthetically pleasing non-separable surface on the microcellular component.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
A door assembly for an opening through which an inflatable restraint safety device may be deployed, said assembly comprising; a frame for supporting an inflatable restraint safety device and an opening presented in said frame; a door disposed in said opening and capable of rapidly moving so that said inflatable restraint device may be deployed through said opening; said assembly characterized by said door including an impact plate portion and a foam portion bonded to said impact plate portion with said foam portion including a microcellular component having a first predetermined density and an integral outer skin component distinct from said microcellular component and formed integral with said microcellular component and having a second predetermined density which is greater than said first predetermined density of said microcellular component for providing an aesthetically pleasing non-separable surface on said microcellular component.
Claim 2
Dependent Claim
139 words
A door assembly for an opening through which an inflatable restraint safety device may be deployed, said assembly comprising; a frame for supporting an inflatable restraint safety device and an opening presented in said frame; a door disposed in said opening and capable of rapidly moving so that said inflatable restraint device may be deployed through said opening; said assembly characterized by said door including an impact plate portion and a foam portion bonded to said impact plate portion with said foam portion including a microcellular component having a first predetermined density and an integral outer skin component distinct from said microcellular component and formed integral with said microcellular component and having a second predetermined density which is greater than said first predetermined density of said microcellular component for providing an aesthetically pleasing non-separable surface on said microcellular component.
Claim 3
Dependent Claim
21 words
