Abstract
The airbag cushion has a passive venting system that remains open or transitions to a closed position depending on the impact of the airbag with an occupant and the position of the occupant. The venting system self closes upon deployment when an occupant is not out of position but remains open when an occupant is out of position. The venting system self closes due to cushion membrane tension.
