Abstract

An air bag cover for a vehicle has a main body formed of a thermoplastic polyurethane elastomer and a skin layer applied over the main body. The skin layer is preferably of an `integral skin` reaction type polyurethane and is applied over the main body. Break lines may be formed in the main body portion of the airbag cover for permitting an inflated air bag to rip the cover for emerging into the vehicle cabin. The polyurethane elastomer of the main body preferably has a Shore A hardness rating of over 80.
