Vented air bag

摘要

An apparatus ( 10 ) helps protect an occupant ( 20 ) of a vehicle ( 12 ). The apparatus ( 10 ) includes an inflatable vehicle occupant protection device ( 14 ) that includes panel ( 100 ) of material that helps define an inflatable volume ( 54 ) of the protection device. A vent opening ( 104 ) vents inflation fluid from the inflatable volume ( 54 ). A pleat ( 120 ) is folded in the panel ( 100 ). The pleat ( 120 ) is positioned against a vehicle surface ( 62 ) while the protection device ( 14 ) is in a normally deployed condition to help block inflation fluid from venting through the vent opening ( 104 ).
