Claim:
An airbag system comprising: an inflatable cushion having a first opening and a second opening; and a fill tube having two open ends and an outlet, wherein the fill tube passes through the first and second openings of the inflatable cushion, and wherein the outlet of the fill tube is positioned within the inflatable cushion and the two open ends of the fill tube are positioned outside of the inflatable cushion, wherein, during inflation of the inflatable cushion, the fill tube expands and at least substantially occludes the first and second openings to limit passage of inflation gas between the fill tube and the perimeter of the first and second openings, and wherein, following inflation of the inflatable cushion, the fill tube at least partially separates from the perimeter of the first and second openings to enable inflation gas to exit the inflatable cushion between the fill tube and the perimeter of the first and second openings.
