Abstract
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.
