1. An airbag assembly comprising:
- an airbag cushion configured to define an interior volume when deployed;
a vent tube comprising a distal end that defines a distal aperture and comprising a proximal end that is coupled with the airbag cushion, wherein the vent tube further comprises a first region and a second region that are at opposite sides of the vent tube;
a first strap portion attached to the vent tube at the first region; and
a second strap portion attached to the vent tube at the second region,wherein the first and second strap portions are configured to be placed under tension to urge the opposite sides of the vent tube together to close the vent tube during deployment of the airbag cushion.

Abstract
An inflatable airbag assembly can include an airbag cushion and a vent tube having an aperture. Portions of one or more straps can be attached to opposite sides of the vent tube, and a release mechanism can selectively retain the one or more straps. Upon deployment of the airbag cushion while the release mechanism retains the one or more straps, the one or more straps can urge the opposite sides of the vent tube toward each other to assist in closing the aperture of the vent tube.

22. An airbag assembly comprising:
-
an airbag cushion configured to define an interior volume when deployed, wherein the airbag cushion defines an aperture; a vent tube comprising a distal end that defines a distal aperture and comprising a proximal end that defines a proximal aperture and is coupled with the airbag cushion, wherein the vent tube further comprises a first region, a second region, and a pair of lateral reinforced regions that are each offset from each of the first and second regions; a first strap portion attached to the vent tube at the first region such that the first region is reinforced; and a second strap portion attached to the vent tube at the second region such that the second region is reinforced; wherein the first and second strap portions are configured to be placed under tension to urge the first and second regions of the vent tube together to close the vent tube during deployment of the airbag cushion. - View Dependent Claims (23, 24, 25)

26. A method of forming an airbag assembly comprising:
-
aligning a proximal aperture in a piece of vent tube material with an aperture in a piece of airbag cushion material, wherein the vent tube material comprises a first flap and a second flap that extend away from the proximal aperture in opposite directions; stitching through the vent tube material and the airbag cushion material around both apertures to join the vent tube material to the airbag cushion material; stitching a first set of lateral sides of the first and second flaps to each other; stitching a second set of lateral sides of the first and second flaps to each other to form a tube structure that includes a distal aperture; and attaching a first strap portion to the first flap at a position between the lateral sides of the first flap and attaching a second strap portion to the second flap at a position between the lateral sides of the second flap. - View Dependent Claims (27, 28, 29, 30)
