Abstract
A front airbag (10) for the protection of a vehicle occupant (12) in a vehicle which is specifically a passenger airbag for the protection of a passenger, in the installed and inflated state includes a contact wall (20) facing the vehicle occupant (12) and an opposite rear wall (22) as well as a first sidewall (24) facing the vehicle center as seen by the vehicle occupant (12) and an opposite second sidewall (26). The airbag (10) further includes a limiting device which, in the inflated state of the airbag (10), prevents the first sidewall (24) from further deploying so that the airbag (10) takes a first volume. The limiting device can be influenced when the head (14) of the vehicle occupant (12) contacts the airbag (10) such that it allows the first sidewall (24) to further deploy so that the airbag (10) takes a second volume larger as compared to the first volume. Accordingly, at least a major part of the volume of the airbag (10) increases in the direction of the vehicle center as seen by the vehicle occupant (12).
