An air bag system for deploying from within a structural element 50 of a vehicle comprising an inflator 55 providing inflation gas in response to an activation signal, a main bag 65 in a folded condition configured for storage in an internal region behind a covering 52 of the structural element, wherein the main bag has a distal end 66 configured to rupture a tear seam 53 in the covering 52, and a shielding bag 60 disposed over the inflator and having a projection body 61 extending away from the inflator to a remote edge within the main bag 65, wherein the projection body is substantially continuous in the direction of the main bag except for at least one gas passage 62 at the remote edge for coupling inflation gas from the inflator to the main bag, wherein 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. The shielding bag may include a reverse fold 123 and a flap 124, 125 disposed on the projection body, wherein inflation of the flap extends the shielding bag in the direction towards the tear seam. |
