Abstract
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.
