Abstract
An airbag cushion venting system is disclosed. The system comprises an airbag cushion body having a cushion vent formed therein. A vent cover is attached to the body such that the vent cover at least partially covers the cushion vent in its unconstrained state. A tieback structure holds the vent cover either away from the cushion vent opening or in a position such that a smaller portion of the cushion vent is covered than is covered in the cushion vent's unconstrained state and is adapted to release the vent cover once the body has expanded a sufficient amount to enable the vent cover to at least partially cover the cushion vent.
