A gas bag in which an orifice is opened or closed with the aid of a control band as soon as the gas bag has reached a predetermined state of deployment. One end of the control band is fastened to a gas bag envelope in the region of the orifice. The control band is connected at its other end to the gas bag envelope so that, when the predetermined state of deployment is reached, the control band slips into the gas bag envelope so that the orifice is closed by the slipped-in region of the gas bag envelope by the internal pressure of the gas bag, or the control band slips out of the gas bag envelope so that the previously closed orifice is opened.
