Abstract

A relatively rigid plastic sheet is molded into the foam seat pad of a motor vehicle seat where it forms part of the exterior surface of the pad. The sheet defines an airbag opening which communicates with a side-impact airbag module adjacent the pad and is positioned against an upholstery seam at a desired location on the seat. Upon actuation, the inflating bag is guided to and through the airbag opening so that the inflated bag is precisely located to provide maximum protection.

Claims

1. In an automotive seat having a seat body covered with upholstery joined at a seam and a resilient foam pad housed in said seat body adjacent an airbag module, said seam having a rupturable seam portion for permitting deployment of an airbag from said module, the improvement which comprises:

a sheet which is relatively more rigid than said foam pad molded onto an outer surface of said foam pad forming a portion of the foam pad'"'"'s external surface, said relatively rigid sheet defining an airbag opening adjacent said rupturable seam portion to guide therethrough an expanding airbag from said module.

2. An automotive seat of claim 1 wherein said sheet is L-shaped in cross section to form a comer edge of said foam pad.

3. An automotive seat of claim 2 wherein said sheet is plastic.

4. An automotive seat of claim 3 wherein said sheet comprises plastic fibers.

5. An automotive seat of claim 4 wherein said fibers comprise woven fibers.

6. An automotive seat of claim 4 wherein said fibers comprise knitted fibers.

7. An automotive seat of claim 4 wherein said fibers comprise a non-woven web.

8. An automotive seat of claim 3 wherein said sheet comprises a non-woven, spun bonded, polypropylene fiber mesh.

9. An automotive seat of claim 1 wherein said foam pad is perforated, forming an airbag deployment passage from said module to said airbag opening.
