Abstract
Abstract The invention relates to an air bag for occupant restraint systems of motor vehicles, which air bag is automatically inflated by means of a gas generator in the event of an accident. In order subsequently to allow slackening of the air bag, a kidney-shaped or crescent shaped zone of the air bag cover, which is arranged at a greater distance from and approximately centrally to a central region of the air bag facing the occupant, is produced from gas-permeable fabric. Due to the specified shape and arrangement of this zone, the necessary load-bearing capacity of the air bag remains guaranteed.
