Abstract

An airbag arrangement for restraining an occupant of a motor vehicle. The vehicle roof is bounded by lateral roof edge regions extending parallel to the longitudinal axis of the vehicle and also bounded by a front window cross member extending transversely with respect to the longitudinal axis of the vehicle. A first section of the folded-up airbag can be arranged along a lateral roof edge region. A second section can be angled away from the first section transversely with respect to the longitudinal axis of the vehicle, wherein the second section of the airbag is arranged along a longitudinal side of the front window cross member. The airbag can be disconnected from the vehicle body in the region of the second section or be connected releasably thereto when the airbag is deployed. Therefore, when the airbag is deployed, the entire second section can be deployed freely.
