Abstract: The present invention comprises a new and improved method and apparatus for packing an inflatable air bag cushion into a housing of an air bag module assembly of an occupant restraint system for a motor vehicle. After securing an inlet chute of the air bag cushion in the open end of the housing and placing the air bag on a flat support with a larger portion of the back wall thereof overlaying a small portion of the back wall with the front wall in between in a folded condition, a central portion of the air bag is clamped by a large blade and subsequently a first edge portion is folded over the central portion and a second opposite edge portion is folded over the first edge portion so that opposite edge fold lines extend outwardly just inside opposite ends of the housing. A rolling clamp is attached transversely across the folded air bag and the air bag is rolled-up on an axis moved toward the housing.

Abstract: A retention system for securing an electrical accessory, such as an electrical connector, to a reaction canister of an inflatable restraint assembly. The reaction canister comprises a trough-shaped body extruded from a continuous length of material and includes at least one screw retaining groove formed integrally with the body during the extrusion thereof. A retention clip includes a pair of legs interconnected by a bridge. Each of the legs has opposed ends. One of the ends of each of the legs mates with the screw retaining groove to attach the clip to the reaction canister. The other end of each of the legs form a cavity for receiving the electrical connector and securing the same to the reaction canister. In another embodiment, the retention clip mates with an attachment feature, separate from the screw retaining groove, and which is also formed integrally with the body during extrusion.

Abstract: The strain of increased airbag snap is alleviated in a throat and mouth construction of the type employing rod pockets in opposed sides of a rectangular airbag mouth. This is achieved by forming the throat material by folding and sewing so that the layers of throat material increase by steps from the single layer adjacent the bag to multiple layers forming the rod pockets.

Abstract: The sidewalls of a reaction canister for a passenger-side airbag module define a pair of opposed, parallel channels on their inner surfaces. A protective cover in the form of a thin rectangular plastic body has two opposite edges thickened to form lobes. These lobes are inserted into the channels before the second end plate is attached to the canister.

Abstract: A one-piece molded plastic retainer is employed to hold each of two opposed edges of an airbag mouth in engagement with a reaction canister. The retainer is sewn, or otherwise secured, in the airbag mouth and includes a rod carrying a pair of integral discs which snap-fit into rails in a diffuser plate. The rails are thereafter slid into channels in the reaction canister. The rod includes a stiffening rib to resist stresses imposed during assembly and during bag deployment.
