Abstract

A reinforced vinyl shell comprises a two layer construction for covering air bag doors that open through the shell when an air bag is deployed. The reinforced vinyl shell includes a first layer of unreinforced vinyl and a second layer is fused to the first layer and is formed of a vinyl material mixed with reinforcing fibers. Such fibers are randomly dispersed in the vinyl and may be comprised of fillers, such as glass, recycled RIM, or recycled vinyl. Other thermoplastic castable materials may be used in place of the vinyl.
