Abstract
Abstract An air bag module includes an inflator for generating gas and an air bag deployable upon generation of gas by the inflator. The air bag module further includes a canister for housing the inflator and a clamshell cover for housing the air bag. The clamshell cover is attached to the canister. Preferably, the clamshell cover includes first and second halves and a bendable thin hinge portion pivotally connecting the first and second halves. Upon air bag deployment, the air bag breaks open and deploys out through the hinge portion of the clamshell cover.
