Claim Text:
1. An airbag comprising: an outer shell defining an interior of the airbag; a divider positioned in the interior so as to divide the interior into a first chamber and a second chamber; and a valve mechanism operatively coupled to the divider, the valve mechanism including: an opening enabling fluid communication between the first and second chambers; and a flap positioned in the second chamber overlying the opening, the flap being 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 also being 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 including 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, wherein the valve is structured so that the at least one non-attachment edge overlaps an edge of the opening during application of the reverse pressure differential to the flap, thereby forming a gas flow passage defined by a portion of the edge of the opening and a portion of the at least one non-attachment edge.
