Abstract
An airbag assembly may include an inflatable curtain airbag with a stowed configuration and a deployed configuration. The inflatable curtain may have a first chamber and a second chamber that inflates forward of the first chamber. The second chamber may have a height above the height of the first chamber so that a bottom of the second chamber is pressed downward adjacent to a door of the vehicle. A plurality of airbag assembly components may be integrally formed with a non-inflating peripheral region surrounding the first and second chambers. Such components may include a front or rear tether cut from the front or rear of the non-inflating peripheral region, a top tether cut from the top of the non-inflating peripheral region to control deployment of the second chamber, and a fabric shield cut from the top to at least partially wrap around the stowed inflatable curtain airbag.
