An apparatus includes a main body substantially enclosing an interior volume. The main body is elastically expandable to an inflated configuration. The apparatus further includes a vent aperture in the main body and a vent cover at least partially overlapping the vent aperture. The vent aperture and the vent cover define a passage from the interior volume to outside of the main body. In the inflated configuration of the main body and within a pressure threshold of the interior volume, the vent cover constricts the passage proportionately to a pressure increase in the interior volume of the main body.

Vehicle airbag with active vent

An inflatable airbag assembly includes first and second walls sealably connected to define an inflatable bladder having an interior volume that is operable between inflated and deflated states. At least one pleat is defined within at least one of the first and second walls, and defines an expanded portion of the interior volume. First and second slits are defined within the first wall that define a vent in communication with the expanded portion of the interior volume, wherein the vent defines an open position with the inflatable bladder in the deflated state, and wherein the vent moves to a closed position as the inflatable bladder operates to the inflated state.
