Abstract
An inflatable restraint deployment system includes a simplified hold-down assembly for fastening an air bag door in a tamper-proof closed position. The deployment system includes an air bag door pivotally supported adjacent an air bag deployment opening in an automobile dashboard and two fasteners that releasably secure the door in a closed position over the air bag deployment opening. The fasteners each include an elongated shaft portion that either extends integrally upward from an air bag canister flange or integrally downward from an air bag door substrate. The fasteners are aligned in the direction of door movement. Each fastener shaft portion extends through one of a pair of fastener holes formed either in the air bag door substrate or in the canister flange. A fastener flange extends outward from around the shaft portion of each fastener and engages a rim that defines one of the fastener holes. Each fastener hole defines an area slightly smaller than the cross-sectional area of the thickest portion of each fastener flange. Either the fastener hole rims or the fastener flanges yield when air bag inflation forces the air bag door to pivot out of the closed position.
