Abstract
An improved air bag module having a manifold designed with integral keys configured to lock the manifold, retainer, air bag and soft cover to the housing. The manifold is elastically deformable and the keys are configured to be inserted into slots in the retainer and housing while the manifold is elastically compressed. Upon releasing the compression force the manifold expands and the keys are locked into the retainer and housing slots locking the individual sub-module pieces together. The air bag and soft cover are trapped between the manifold and the retainer during assembly. The soft cover and module housing are configured to open upon air bag deployment, allowing the air bag to inflate outside of the air bag module.
