Abstract

The invention relates to a collision-protection system for passengers of motor vehicles. In a manner which is known in principle, an airbag is automatically inflated in the event of an accident. In order to control the direction and speed of expansion, the airbag is wholly or partially encased by a tough, plastically deformable film, which is overstretched and torn open as the airbag is inflated.
