Abstract
Airbag assemblies and active vents for airbag assemblies are disclosed. An airbag assembly may include an airbag cushion, an active vent having an aperture and a patch configured to plug the aperture, a depth-delimiting tether, a cross tether, and a control tether. The control tether may be coupled to the patch and the depth-delimiting tether. The depth-delimiting tether and the control tether may be drawn taut as the airbag cushion expands during deployment to draw the patch toward the aperture from a first position that allows unobstructed venting to a second position that obstructs venting through the aperture. The depth-delimiting tether and the control tether can be in or transition to a slack state due to occupant impact with the airbag cushion. These tethers may also be in a slack state during the early stage of deployment.
