Gassack für eine Insassen-Schutzeinrichtung

A gas bag for an occupant protection device in motor vehicles that includes a gas bag configured to be inflated by a gas generator. The gas bag has an envelope surface that is assigned to a vehicle occupant to be protected and an envelope that forms, in the inflated state, a gap leading into the envelope surface. The gap is defined along longitudinal sides by first and second sections of the gas bag that are opposite one another. The gas bag is configured so that a body part facing the gas bag of a vehicle occupant who is sitting outside a normal seating position can penetrate the gap as the gas bag inflates thereby expanding the gap. Additionally, the first and second sections of the gas bag are restrained relative to one another so that the first section and the second section close the gap after inflation of the airbag in order to prevent the penetration of a body part of a vehicle occupant into the gap after the complete inflation of the gas bag.
