ABSTRACT:
A safety device in the form of an airbag for motor vehicles is disclosed wherein, from a specified vehicle deceleration onwards, the airbag is located inflated in front of a vehicle occupant. The airbag has outlet openings in its cover which permit the gas volume to be partially forced out, the airbag resting with a support surface against a curved windscreen surface and having on its opposite side an impact surface for the vehicle occupant when inflated. The impact surface is approximately aligned in the vehicle transverse direction. The outlet openings have an enlarged opening cross-section for the emergence of gas near to a greatest curvature region of the windscreen surface in relation to a vehicle transverse axis. As a result of this enlarged opening cross-section, the airbag is purposefully more strongly compressed in this region on being impacted by a vehicle occupant.
