Patent ID: 7237802

Claim:
An airbag cushion comprising: an airbag cushion body having a cushion vent formed therein; a vent cover attached to the body; and a tieback structure adapted to hold the vent cover in a constrained state and to release the vent cover into an unconstrained state to at least partially cover the cushion vent upon sufficient expansion of the airbag cushion body; wherein the tieback structure and the airbag cushion body are adapted to prevent the vent cover from being released from the constrained state or to enable the vent cover to be released into the unconstrained state depending on an occupant's position adjacent to the airbag cushion body when the airbag is deployed; wherein the constrained state of the vent cover is achieved by either holding the vent cover away from the cushion vent opening via the tieback structure or by holding the vent cover via the tieback structure such that a smaller portion of the cushion vent is covered than is covered in the unconstrained state of the vent cover.
