description An air bag system deploys from within a structural element of a vehicle. A main bag is configured for storage in a folded condition in an internal region behind a covering of the structural element, wherein the main bag has a distal end configured to rupture a tear seam in the covering. A shielding bag is disposed over an inflator and has a projection body extending away from the inflator to a remote edge within the main bag. The projection body is substantially continuous in the direction of the main bag except for at least one gas passage at the remote edge for coupling inflation gas from the inflator to the main bag. The main bag has a fold proximate to the gas passage so that inflation of the main bag begins with the unfolding of the fold in a manner that displaces the main bag toward the tear seam.
