Abstract
The airbag (10) protection for the car occupants is made from a webbing reinforced fabric which is sewn into a cushion shape. The inflating gas is introduced via a profiled entry slot. One corner of the bag is sewn across with a stitched seam (24) to separate the bag from venting holes (46) in the tag so formed. As the pressure in the airbag reaches a set level the stitches are torn out and a controlled release of air follows, without deflating the bag too rapidly. The seam can also be formed by thermoplastic moulding or by special adhesives.
