Passenger side air bag module
First Claim
1. An air bag module for a vehicle comprising:
- an inflator;
an air bag cushion;
a panel member having a recessed cavity, said recessed cavity being defined by an end wall that substantially closes a first end of said recessed cavity and a plurality of integrally formed reaction walls for directing said airbag cushion out of said recessed cavity and through a second, open end of said recessed cavity opposite said first end when said air bag module is deployed;
a deployment door fastened to said panel member and having a retaining bead, a trim portion and a pliant spacing leg, said trim portion coupled to a first end of said spacing leg and said retaining bead coupled to a distal end of said spacing leg; and
a manifold coupled to said panel member and positioned within said recessed cavity, said manifold having a retaining bead channel for receiving said retaining bead to thereby flexibly couple said manifold and said deployment door together, said manifold housing said inflator and directing a volume of gas therefrom during deployment of said air bag module, said manifold being coupled to an open end of the airbag cushion but not otherwise directing the airbag cushion when the air bag module is deployed.

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.

7. An air bag module for a vehicle comprising:
-
an inflator;
an air bag cushion;
a front dash panel having a plurality of trim portion retaining apertures and a recessed cavity, said recessed cavity being defined by an end wall that substantially closes a first end of said recessed cavity and a plurality of integrally-formed reaction walls for directing said air bag cushion out of said recessed cavity and through a second end of said recessed cavity opposite said first end when said air bag module is deployed;
a deployment door having a retaining bead, a pliant spacing leg and a trim portion with a plurality of snap-fasteners, said trim portion coupled to a first end of said spacing leg and said retaining bead coupled to a distal end of said spacing leg, said snap-fasteners engaging said trim portion retaining apertures and coupling said deployment door to said front dash panel; and
a manifold coupled to said panel member and positioned within said recessed cavity, said manifold having a retaining bead channel for receiving said retaining bead to thereby flexibly couple said manifold and said deployment door together, said manifold housing said inflator and directing a volume of gas therefrom during deployment of said air bag module, said manifold being coupled to an open end of the airbag cushion but not otherwise directing the airbag cushion when the airbag module is deployed.
