Abstract: An airbag module including an inflatable airbag and an inflator. The airbag is formed by a main panel and a pair of side panels and deploys into a position to contact the occupant. The airbag includes a tether connected to the main panel at one end and is anchored proximate to the inflator at the other end. Prior to inflation, the airbag includes a pre-folded portion adjacent to the tether. The airbag is configured so that during an initial stage of the inflation process the tether is fully extended and the pre-folded portion remains folded and during a final stage of the inflation process the tether separates into at least two portions thereby allowing the pre-folded portion to unfold and the airbag to fully deploy.

Abstract: An airbag arrangement with a gas bag inflatable by a gas generator to protect a vehicle occupant, whose envelope defines an interior space of the gas bag that can be filled with gas, with a vent opening through which gas can flow out, with an apparatus for controlling the cross-section of the vent opening including a covering part with which the vent opening can be covered to at least partly closed. The arrangement also includes an inflatable gas duct which interacts with the covering part to vary the cross-section of the vent opening. The duct is inflatable by a secondary gas generator, which during inflation interacts with the covering part such that it changes the cross-section of the vent opening. Rotational movement of the inflatable gas duct is restricted by an extended panel secured to the gas bag, a tab anchored nearby, or both.
