The airbag module as claimed in claim 1, wherein the state variable is a pressure inside the gas sack. 3. The airbag module as claimed in claim 1, wherein the inner space of the gas sack package is evacuated for compacting the gas sack package. 4. The airbag module as claimed in claim 1, further comprising a carrier of the airbag module for carrying the gas sack package, wherein the movement generating device is arranged on the carrier. 5. The airbag module as claimed in claim 4, wherein the movement generating device is arranged in a through-opening of the carrier, so that a free end portion of the movement generating device, via which pressure for acting on the movable element is provided, protrudes along a first direction out of said through-opening, and wherein the free end portion of the movement generating device faces the movable element along the first direction. 6. The airbag module as claimed in claim 5, wherein the free end portion of the movement generating device is arranged along the first direction in or in front of a further through-opening of a component of the airbag module arranged in the inner space of the gas sack package. 7. The airbag module as claimed in claim 5, further comprising a shell for carrying the movement generating device, wherein said shell encompasses the movement generating device and is, for fixing the movement generating device to the carrier, fixed to a circulating boundary region of the through-opening of the carrier. 8. An airbag module for a motor vehicle, comprising: a gas sack package, comprising: a gas sack,a movable element configured and provided to influence a state variable of the gas sack, anda gas-tight protective covering that defines an inner space of the gas sack package, wherein the gas sack and the movable element are arranged in said inner space, anda movement generating device configured and provided to move the movable element, in order to influence the state variable,wherein the movement generating device is arranged separately outside the inner space of the gas sack package such that the movement generating device is at least separated by the protective covering from components of the airbag module arranged in the inner space of the gas sack package,wherein the movement generating device is configured and provided to move the movable element out of an initial position, in which the movable element does not influence said state variable, in a way that the movable element influences said state variable. 9. The airbag module as claimed in claim 8, wherein the movable element is fixed in its initial position to a part of the airbag module arranged in the inner space of the gas sack package. 10. The airbag module as claimed in claim 9, wherein the movable element is fixed through a predetermined breaking connection to the part of the airbag module, wherein said predetermined breaking connection, upon moving of the movable element out of its initial position, is severed. 11. The airbag module as claimed in claim 8, wherein the movable element is configured and provided to close a discharge opening of the airbag module in its initial position, through which, in an opened state, gas can escape out of the gas sack, wherein the movable element upon moving out of the initial position sets free the discharge opening so that gas can escape through the discharge opening out of the gas sack. 12. The airbag module as claimed in claim 8, wherein the movable element is configured and provided to fix in its initial position a tether to the airbag module in a way, that a closure of a discharge opening of the gas sack interacting with the tether closes said discharge opening, wherein the movable element upon moving out of the initial position sets free the tether, so that said closure is opened. 13.
