Air bag module with gas augmentation

摘要

An air bag module includes an inflatable air bag having an inflation opening and an inflator for discharging inflation gas upwardly towards the inflation opening to inflate the air bag. The module includes a container for housing the inflator and air bag which includes elongated side walls. One of the side walls includes a longitudinally elongated and generally vertical segment spaced above the inflator and below the inflation opening of the air bag. The segment has a plurality of aspiration holes therein to aspirate ambient air. A longitudinally extending rib projects inwardly into the container and is positioned directly subjacent the segment and above the inflator. Advantageously, the rib strengthens the side wall and increases ambient air aspiration by directing discharging inflation gas over the aspiration holes of the segment.
