Abstract:
1. An airbag module, comprising: an inflatable airbag cushion comprising a cushion membrane which defines an interior of the inflatable airbag cushion; at least one closeable vent comprising a cinch tube having a base end opposite from a terminal end, wherein the terminal end has a rim that defines an aperture; and a tether connected to the terminal end of the cinch tube at a first end in a configuration that permits the aperture of the cinch tube to be closed by cinching the rim together, and anchored to the cushion membrane at a second end, wherein full inflation of the inflatable airbag cushion creates a cushion membrane tension, and wherein the vent is configured such that the rim of the aperture is brought together by movement of the tether to close the vent without having to overcome resistance from the cushion membrane tension around the vent.
