Abstract: A restraint system for helping to protect an occupant of a vehicle having a roof and a cabin with a seat for the occupant includes an airbag mounted to the vehicle roof. The airbag has a stored condition and is inflatable to a deployed condition having a front-facing occupant receiving portion and an opposite rear-facing portion facing away from the occupant. The airbag has one or more connections with the vehicle roof, with the airbag and the connections being configured such that the roof serves as a reaction surface for supporting the airbag against movement in response to a forward moving occupant impacting the occupant receiving portion. The system is non-reliant on the rear-facing portion of the airbag engaging and using vehicle structure as a reaction surface for supporting the airbag against movement in response to the impacting occupant.

Abstract: An apparatus for helping to protect an occupant of a vehicle includes a curtain airbag inflatable from a stored condition in which the airbag is rolled and/or folded to a deployed condition in which the curtain airbag is positioned between a side structure of the vehicle and the vehicle occupant. The curtain airbag comprises an inflator mouth configured to receive an inflator. The curtain airbag comprises a bracket tab proximate to the inflator mouth and configured to receive an inflator bracket. A tether has first and second end portions. The first end portion of the tether is connected to a portion of the curtain airbag adjacent to the bracket tab. The second end portion of the tether is connected to the bracket tab.

Abstract: A curtain airbag configured to maintain an internal working pressure of the airbag when an internal working pressure exceeds a design working pressure. The curtain airbag can include pressure relief elements that are actuatable to increase the inflatable volume of the curtain airbag. The curtain airbag can include a relief vent that opens when the internal working pressure exceeds the design working pressure and subsequently close when the internal working pressure falls below the design working pressure.
