Abstract: An air bag module which includes a panel member having an integral reaction canister having a plurality of reaction walls and a manifold assembly having a manifold. The manifold includes at least one deployment door retaining channel and is operable for retaining an air bag cushion, an inflator, and a deployment door. The deployment door includes at least one retaining bead and a trim portion which are separated by a pliant spacing leg. As the reaction canister is incorporated into the panel member, the need for a separate reaction canister component is eliminated, thereby reducing cost, weight and overall size of the air bag module and allowing the manifold assembly to be used across a wider range of vehicles. The retaining bead and spacing leg flexibly couple the cover door to the manifold and allow the cover door to be repositioned during installation of the manifold assembly into the panel member so as to eliminate gaps, puckering and other defects in the appearance or the vehicle interior.
