A curtain airbag is proposed to improve the deployability of an airbag cushion while simplifying the structure of the curtain airbag by forming a sub-chamber. The curtain airbag includes a main chamber of an airbag cushion secured to an upper end inside a vehicle body to be deployed to a lower end thereof, a first sub-chamber of the airbag cushion deployed above a pillar trim while pushing the vehicle body to move the main chamber towards a center of a vehicle, and a second sub-chamber of the airbag cushion deployed between an end of the pillar trim and the main chamber, thus pushing the main chamber to prevent the main chamber from being caught by the end of the pillar trim.

The invention relates to a restraint system for a vehicle occupant (26) in a motor vehicle, comprising a front airbag (28), in particular a driver's airbag, and a side airbag (14), in particular a curtain airbag. In the inflated state, the side airbag (14) is arranged and shaped in such a way that, in the event of a glancing impact of the vehicle occupant (26) on the front airbag (28), the side airbag (14) provides no significant support for the front airbag (28) in the vehicle transverse direction (y) in a front open region (20), relative to the direction of travel (x) of the vehicle, of the vehicle side below the A-pillar (12).

A trim assembly for deploying an airbag element, a vehicle including such a trim assembly and a method for manufacturing such a trim assembly. The trim unit includes a vehicle body portion, a trim unit and at least one fixing element. The fixing element is configured to attach the trim unit to the vehicle body portion. The airbag element is arranged between the trim unit and the vehicle body portion. The trim unit is configured to cover at least partially the airbag element. The trim unit is pivotable about the fixing element such that the trim unit is tilted away from the vehicle body portion during a deployment of the airbag element.

An adaptor for connecting a fill tube to an inflator includes a sleeve configured to fit over a discharge end portion of the inflator and to be connected to the inflator. The adaptor also includes an end portion comprising a nipple configured to receive and connect with the fill tube, wherein the sleeve is configured to direct inflation fluid discharged from the inflator toward the nipple, and the nipple is configured to direct the inflation fluid into the fill tube.

A vehicle detects a rotation angle of a seat, controls activation of a first type of roof airbag module provided in a central portion of a headlining and located at a side of the seat when the detected rotation angle of the seat is greater than a first reference angle and less than or equal to a second reference angle, controls activation of the first type of roof airbag module and a second type of roof airbag module provided in the central portion of the headlining and provided at a rear of the seat when the detected rotation angle of the seat is greater than the second reference angle and less than or equal to a third reference angle, determines whether a collision with an obstacle has occurred during traveling, and deploys and expands the activated airbag module when determining that the collision with the obstacle has occurred.

A deployment ramp for helping to direct a curtain airbag to deploy inboard of a trim piece on a side structure of a vehicle includes a deployment flap for directing the curtain airbag to deploy inboard of the trim piece and a mounting portion configured to receive a fastener for connecting the deployment ramp and the curtain airbag to the vehicle. The mounting portion includes a pair of mounting tabs. Each mounting tab is configured to be installed in a corresponding sleeve in the curtain airbag to connect the deployment ramp to the curtain airbag. The mounting portion is configured so that installing both mounting tabs in their corresponding sleeves requires the application of external manipulating forces to the mounting portion in order to bend and/or deflect in order to overcome an interference between the mounting portion and the curtain airbag.
