An air bag apparatus for use in a vehicle instrument panel is provided. The air bag apparatus is located on the passenger's side of the vehicle, and includes a canister integrally molded into the instrument panel. The canister has an opening and is configured to receive an air bag module which attaches to the canister. The canister is covered by a door that is precisely located to cover the opening in the canister. Because the canister is integrally molded into the instrument panel, assembly and installation of a separate canister is eliminated. This reduces production time, reduces the complexity of assembly, and lowers overall vehicle production costs.
