Abstract
A curtain airbag system for an automotive vehicle is disclosed. The system includes a curtain module substantially embedded in the roof rail in its normal, non-inflated state. The module includes an inflatable curtain attached to an inflator. The inflatable curtain has a forward portion. An elongated and inflatable extension is attached to the forward portion of the curtain. When the curtain is inflated in an impact event, the elongated and inflatable extension extends from the curtain and at least partially overlaps the A-pillar and at least part of the grab handle. The elongated and inflatable extension is a first extension that extends from the forward portion of said curtain. The inflatable curtain may include a second, triangular-shaped extension extendable from the forward portion of the curtain when the curtain is inflated.
