Abstract: The disclosed airbag for a motor vehicle for supporting the knees of a vehicle occupant in the event of a crash, comprises an inflatable portion, a first fastening region for fastening the airbag to a motor vehicle part, at least one second, detachable fastening region for fastening the airbag to the same or different motor vehicle part, and a connection located between the second, detachable fastening region and the inflatable portion. The second, detachable fastening region is configured to detach from the inflatable portion if a force exceeding a predetermined value acts on the connection between the second, detachable fastening region and the inflatable portion.

Abstract: An annular airbag is disclosed, of the type where the center piece (12) of the steering wheel cover (11) (mostly embodied as the emblem of the vehicle producer) remains in place during the unfolding process. In order to prevent a vehicle occupant impacting the hole arising above the center piece with an inflated airbag, the tubular region (17) of the airbag above the center piece is embodied such that the cross-sectional area thereof in the inflated state reduces in the direction of the upper plate of the airbag from the center piece (12). The above is achieved, for example, by means of a special forming of the tubular region, by provision of pockets (21) and/or folds (31), the use of special materials, a special fixing of the airbag to the airbag module (9), or the fitting of tension straps (50).
