Abstract
An air curtain assembly includes a side air curtain having a top edge and being inflatable from an uninflated position to an inflated position. In the uninflated position, the side air curtain extends along a longitudinal axis. A first flap is attached to the top edge and an elongated flap is attached to the first flap. The elongated flap extends from the first flap at an angle relative to the longitudinal axis. As such, as the air curtain inflates from the uninflated position to the inflated position, the elongated flap is disposed between the side air curtain and a side roof rail of the vehicle to limit or prevent abrasion of the side air curtain as the side air curtain is inflated.
