10. The gas bag arrangement according to claim 9 , wherein
the gas bag includes at least one first, second and third chamber which in the deployed condition of the gas bag extend one behind the other along the front window of the vehicle,
wherein the second chamber is located between the first and the third chamber, and the second chamber is separated from the first chamber via a first separating element and from the third chamber via a second separating element,
wherein the first separating element extends at least approximately along a first plane and the second separating element extends along a second plane oriented at an angle to the first plane.
11. The gas bag arrangement according to claim 1 , further comprising a gas generator for inflating the gas bag and a flexible gas conducting means extending in the interior of the gas bag for conducting the gas generated by the gas generator.
12. The gas bag arrangement according to claim 1 , wherein the means for moving include at least one connecting element which is connected with the gas bag and connectable with the vehicle, wherein the connecting element is formed elastic or the gas bag arrangement includes restoring force generating means via which the connecting element is connected with the gas bag or connectable with the vehicle.
13. A gas bag arrangement for a motor vehicle, comprising:
a gas bag which can be deployed for the protection of a person present outside the vehicle along at least a section of a front window and/or another portion of an outside of the motor vehicle; and
a housing in which the gas bag is arranged, wherein the housing is different from a cover of a receiving region of the motor vehicle, which extends in front of the front window; and wherein
the housing is designed such that it at least partly covers the gas bag towards the cover of the motor vehicle-based on the situation with the gas bag arrangement being mounted in the vehicle, and
the housing comprises a first and a second housing part, wherein the first housing part includes an opening for introducing the gas bag into the housing and the second housing part at least partly covers the opening in the first housing part, wherein after assembly of the gas bag arrangement the second housing part covers the gas bag towards the cover of the motor vehicle, and wherein the first housing part is connected with the second housing part,
a gas bag which can be deployed for the protection of a person present outside the vehicle along at least a section of the front window and/or another portion of an outside of the motor vehicle; and
a means for moving at least a section of the inflated gas bag out of the field of view of the vehicle operator, wherein
the means includes at least one connecting element which is connected with the gas bag and connectable with the vehicle, and wherein
the means comprises a guiding device in which the connecting element is at least partly guided along an edge of the inflated gas bag.
14. The gas bag arrangement according to claim 13 , wherein the connecting element is at least partly guided along a portion of the edge of the inflated gas bag, which extends at least approximately parallel to a plane defined by the transverse vehicle direction and vehicle height direction and/or parallel to a plane defined by the longitudinal vehicle direction and the vehicle height direction.
15. The gas bag arrangement according to claim 13 , wherein the guiding device includes at least one loop protruding from the inflated gas bag, through which the connecting element is guided.
16. The gas bag arrangement according to claim 15 , wherein the guiding device includes a plurality of loops spaced from each other.
