Abstract: An apparatus for helping to protect an occupant of a vehicle comprises an airbag having a primary chamber and a secondary chamber. The primary chamber has a stored condition and is inflatable to a deployed condition to cover a portion of the vehicle. The secondary chamber has a stored condition and is inflatable to a deployed condition to cover portions of the vehicle left uncovered by the primary chamber. At least one passive vent provides fluid communication between the primary and secondary chambers. At least one active vent is actuatable to provide fluid communication between the primary and secondary chambers. An inflator is actuatable to provide inflation fluid to the primary chamber. The at least one passive vent directs inflation fluid from the primary chamber into the secondary chamber. The at least one active vent is actuatable to direct inflation fluid from the primary chamber to the secondary chamber.

Abstract: An airbag module includes a bag wrap, a retainer, an airbag, and an inflator to inflate the airbag. The airbag includes at least one vent hole, and a deployment control flap to change trajectory of the airbag such that the airbag will deploy upwards and laterally to left and right sides. The deployment control flap is fixed at both ends to the retainer, airbag, or bag wrap.

Abstract: A part of a distal end portion of an airbag is tucked into an interior thereof. A plurality of overlapping longitudinal folds are formed in first and second halves of the airbag, and the folded distal and proximal portions of the airbag are each folded substantially transverse to the longitudinal folds so as to form two compact fold bodies.

Abstract: The present invention provides a method of folding an airbag, wherein the airbag is folded compactly to fit into a receptacle such as an airbag housing. The method includes the step of inwardly tucking an end portion of the airbag, thereby forming upper and lower portions of the airbag bounding the tucked end region. The method further includes the steps of longitudinally folding first and second halves of the airbag, and folding the airbag a plurality of times transversely to form two compact fold bodies.
