Abstract

An airbag for a motor vehicle, with at least one inflatable region which is capable of being inflated by means of a gas generator and in the inflated state forms a lateral curtain for protecting a vehicle occupant. When inflated the airbag is clamped between two points on the vehicle body which are separated from each other in the longitudinal direction of the vehicle. The airbag has a separation region, which may be an opening, that is bridged by a tautening element which is capable of being inflated together with the inflatable region. When the airbag inflates the opening deforms reducing the length of the opening in the longitudinal direction of the vehicle.
