1. A curtain airbag assembly for use in a vehicle, the curtain airbag assembly comprising:
- an airbag inflator configured to expel an inflation gas; and
a curtain airbag configured to receive the inflation gas from the airbag inflator, the curtain airbag comprising;
a first standoff chamber configured to contact a roof rail above a window of the vehicle during a curtain airbag deployment event; and
an angled stiffening chamber disposed adjacent to and in fluid communication with the first standoff chamber, the angled stiffening chamber configured to span across a window opening of the vehicle during the curtain airbag deployment event, the angled stiffening chamber comprising;
an opening to receive inflation gas from the first standoff chamber,a first extending portion extending in a first direction;
a second extending portion extending in a second direction that differs from the first direction;
a first bent portion disposed between and in fluid communication with the first extending portion and second extending portion; and
a second bent portion disposed adjacent to and in fluid communication with the second extending portion; and
a plurality of stiffener adjusting regions configured to at least partially define one or more of the first bent portion, the second bent portion, the first extending portion, and the second extending portion; and
a second standoff chamber configured to contact a beam at the bottom of the window of the vehicle during the curtain airbag deployment event, wherein the second standoff chamber is disposed adjacent to and in fluid communication with the angled stiffening chamber, and the angled stiffening chamber extends in a generally vertical direction between the first standoff chamber and second standoff chamber.

14. A curtain airbag assembly for use in a vehicle, the curtain airbag assembly comprising:
-
an airbag inflator configured to expel an inflation gas; a curtain airbag configured to receive the inflation gas from the airbag inflator, the curtain airbag comprising; a first inflatable standoff chamber configured to deploy to contact a first beam or pillar of the vehicle during a curtain airbag deployment event; and an inflatable angled stiffening chamber configured to deploy to span across a window opening of the vehicle, the inflatable angled stiffening chamber disposed adjacent to and in fluid communication with the first inflatable standoff chamber; a first non-inflatable stiffener adjusting region disposed on a first side of the inflatable angled stiffening chamber to define a first bend in the inflatable angled stiffener chamber; and a second non-inflatable stiffener adjusting region disposed on a second side of the inflatable angled stiffening chamber opposite and longitudinally displaced from the first non-inflatable stiffener adjusting region, wherein the second non-inflatable stiffener adjusting region defines a second bend in the inflatable angled stiffening chamber. - View Dependent Claims (15, 16, 17, 18)
