A duct is operative along and inside an outboard boundary of an air bag is adapted to distribute inflation gas to a distal portion thereof. A proximal second opening in the duct provides for fluid communication between the duct and interior of the air bag, but is normally obstructed by a valve element. A control element provides for opening the valve element when the air bag is sufficiently inflated in the absence of an out-of-position occupant, so as to provide more rapidly inflating the air bag through the second opening. A relatively distal third opening in the duct provides for fluid communication between the duct and the interior of the air bag, and the air bag is vented from the duct through a relatively distal vent along an outboard boundary.
