Abstract:
1. An airbag assembly comprising: an airbag cushion that defines an inflatable chamber into which inflation gases can be received to inflate the airbag cushion, wherein the airbag cushion comprises a first panel that is configured to face toward a vehicle occupant and a second panel that is configured to face in a direction that is other than toward the vehicle occupant during deployment of the airbag; an active vent that comprises: a control tether coupled at a first end to the patch and fixedly coupled at an opposite second end to a panel of the airbag cushion opposite the second panel, wherein the control tether is configured to transition from a slack condition to a taut condition as the cushion expands during deployment to transition the active vent from a high-rate venting capacity state that allows unobstructed venting through the aperture to a lower-rate venting capacity state that partially obstructs venting through the aperture, and wherein the control tether, in the taut condition as the cushion further expands during deployment, is further configured to transition the active vent from the lower-rate venting capacity state to a closed state.
