Abstract: The airbag comprises an outer skin (20) having a first opening (26), a flap (32) being at least indirectly attached to the outer skin (20), and a tether (37). The first end of the tether is attached to a flap (32) and the second end (37b) of the tether is detachably attached to a holding element (16). When the airbag is deployed and the tether (37) is under tension, the flap (32) covers the first opening (26) at least partially such that the ventilation device is in a closed or throttled first state. When the airbag is deployed and the tether (37) is not under tension because the second end (37b) of the tether is detached from the holding element, the flap (32) covers the first opening (26) less than in in the first state, such that the ventilation device is in second state. The flap (32) is located between the outer skin (20) and an additional layer (34) having a second opening (36) at least partially overlapping the first opening (26).

Abstract: A frontal airbag unit adapted for being mounted above the person to be protected is described. It comprises an inflator (24) and an airbag consisting of a first outer skin (10) enclosing a filling and support chamber (20) and a second outer skin (30) enclosing a protection chamber (40). In order simplify the production process and in order to provide a good support for the deployed second outer skin (30) the first outer skin (10) is comprised of a first layer (11) and a second layer (12) being connected to one another by means of a first peripheral connection such that the filling and support chamber (20) is relatively flat.
