Abstract

An airbag of a vehicle occupant restraint system has an actively releasable tether element (14) disposed in an interior (16) of the airbag (10) which is connected, at an airbag-side fixation (18), permanently to the airbag (10) in the region of a contact zone (20) for the occupant, and which comprises a detachable fixing point (22) for the release. The airbag (10) can take up a smaller first filled volume (V1) in which the tether element (14) and the detachable fixing point (22) are not released, and a larger second filled volume (V2) in which the tether element (14) is released at the actively detachable fixing point (22). In addition to the tether element (14), a tether element restrainer (26) disposed in the interior (16) of the airbag (10) is provided which acts upon a point of action (28) on a vehicle-side portion (34) of the tether element (14) distant from the airbag-side permanent fixation (18) of the tether element (14) and which is permanently fixed to a coupling point (30) distant from the contact zone (20) so that the vehicle-side portion (34) of the released tether element (14) remains connected fixedly to the vehicle via the tether element restrainer (26).
