Abstract

An airbag for a motor vehicle capable of adjusting its internal pressure to the size of a vehicle occupant and to the accident situation. This adaptation is achieved by purely passive means. The airbag includes an airbag cover enclosing a gas chamber and also has at least one venting arrangement which connects the gas chamber with an external environment. Gas flow through the venting arrangement is throttled or blocked when a certain area of the airbag cover meets an obstacle. The venting arrangement includes at least one opening in the airbag cover and a tube which is connected with the airbag cover. The at least one opening ends in the tube, and the tube includes an exit opening to the external environment.
