Airbag (with optional membrane) covering side window

The airbag is stored in a duct 7 in door frame 4. It is anchored at points 11 and 13, and inflated by gas generator 5 through hose 6. A webbing strap 9 has a rear anchorage 10, which ensures that the inflated bag covers the B-post. The airbag comprises interconnected cells 8. Front and rear cloths may be sewn together at selected points (25, fig. 2) and may be combined with a web (27, fig. 2). The bag may cover front and rear windows (fig. 6), and offers protection in side impacts or rollovers.
