An airbag includes an outer shell defining an interior of the airbag, and a divider positioned in the interior so as to divide the interior into a first chamber and a second chamber. A valve mechanism is operatively coupled to the divider. The valve mechanism includes an opening enabling fluid communication between the first and second chambers, and a flap positioned in the second chamber overlying the opening. The flap is structured to deflect in a direction away from the opening responsive to a pressure differential urging a flow of gas from the first chamber through the opening into the second chamber. The flap is also structured to block the opening responsive to a reverse pressure differential urging a flow of gas from the second chamber through the opening into the first chamber. The flap includes at least one attachment edge along which the flap is attached to the divider and at least one non-attachment edge along which the flap is not attached to the divider. The valve is structured such that at least a predetermined minimum distance between the at least one non-attachment edge and an edge of the opening is maintained during application of the reverse pressure differential to the flap.
