An active bolster for a vehicle is provided, wherein the bolster comprises an expansible hollow interior that is inflatable and is self-supporting in both an inflated and in an uninflated position. The bolster has an inflator module for inflating the expansible hollow interior. The bolster has an inner wall for projecting inwardly into the vehicle and away from the side of the vehicle on inflation of the expansible hollow interior. The bolster may have a relatively non-expansible component located between a first expansible chamber and a second expansible chamber. The bolster may comprise an outer wall having an attachment portion for attaching the outer wall to a portion of the side of the vehicle.

Airbag cushion assemblies comprising an airbag inflation tunnel positioned within an airbag cushion. Some embodiments may comprise an airbag cushion comprising an inflator opening and an airbag inflation tunnel coupled to the airbag cushion. The inflation tunnel may be configured to direct inflation gas from an inflator positioned within the inflator opening down the airbag inflation tunnel upon deployment of the inflator. A plurality of directional vent openings may be positioned within the airbag inflation tunnel that may be configured to direct the inflation gas laterally relative to the inflator. The inflation tunnel may further be configured such that the inflation gas contacts a terminal end of the inflation tunnel prior to exiting the plurality of directional vent openings.

A curtain airbag for a vehicle may include a curtain airbag cushion, a first folding portion formed from an indoor side to a window side of the curtain airbag cushion, at a predetermined distance rearward from a front end of the curtain airbag cushion, a second folding portion formed from the indoor side to the window side of the cushion airbag at a predetermined distance rearward from the first folding portion, a panel tether connecting the first folding portion and the second folding portion to each other on the window side of the curtain airbag cushion, the panel tether being shorter than a length of the window side of the curtain airbag cushion between the first folding portion and the second folding portion, and a protruding portion protruding inward between the first folding portion and the second folding portion of the curtain airbag cushion by tension of the panel tether.
