The invention claimed is: 1. An airbag module ( 10 ) comprising a housing ( 12 ), a folded airbag ( 16 ) and a flexible fixation ( 14 ) which fixes the folded airbag ( 16 ) on the housing ( 12 ), wherein a tensioning device ( 24 ) is provided by which the fixation ( 14 ) can be brought from an initial state to a tensioned state, wherein the fixation ( 14 ) is connected to the housing ( 12 ) by a seam ( 44 , 46 ). 2. The airbag module according to claim 1 , wherein the fixation ( 14 ) is made from fabric material. 3. The airbag module according to claim 1 , wherein the tensioning device ( 24 ) includes a lug ( 26 ). 4. The airbag module according to claim 3 , wherein the lug ( 26 ) is attached to the housing ( 12 ) by a hinge ( 34 ). 5. An airbag module ( 10 ) comprising a housing ( 12 ), a folded airbag ( 16 ) and a flexible fixation ( 14 ) which fixes the folded airbag ( 16 ) on the housing ( 12 ), wherein a tensioning device ( 24 ) is provided by which the fixation ( 14 ) can be brought from an initial state to a tensioned state, wherein the tensioning device ( 24 ) includes a lug ( 26 ), and wherein the fixation ( 14 ) is sewn to the lug ( 26 ). 6. The airbag module according to claim 5 , wherein the fixation ( 14 ) is connected to the housing ( 12 ) by a seam ( 44 , 46 ). 7. An airbag module ( 10 ) comprising a housing ( 12 ), a folded airbag ( 16 ) and a flexible fixation ( 14 ) which fixes the folded airbag ( 16 ) on the housing ( 12 ), wherein a tensioning device ( 24 ) is provided by which the fixation ( 14 ) can be brought from an initial state to a tensioned state, wherein the tensioning device ( 24 ) includes a lug ( 26 ), and wherein the lug ( 26 ) is fixed on a stop element ( 48 ). 8. The airbag module according to claim 7 , wherein the fixation ( 14 ) is connected to the housing ( 12 ) by a seam ( 44 , 46 ). 9. A method of mounting the airbag module ( 10 ) according to claim 1 , comprising the following steps: a) folding an airbag ( 16 ) and inserting the airbag into a housing ( 12 ), b) fastening a fixation ( 14 ) on the housing ( 12 ), and c) bringing the fixation ( 14 ) to a tensioned state in which the airbag ( 16 ) is fixed by means of a tensioning device ( 24 ) which is attached to the housing ( 12 ), wherein the fixation ( 14 ) is sewn to the housing ( 12 ). 10. A method of mounting an airbag module ( 10 ), comprising the following steps: a) folding an airbag ( 16 ) and inserting the airbag into a housing ( 12 ), b) fastening a fixation ( 14 ) on the housing ( 12 ), and c) bringing the fixation ( 14 ) to a tensioned state in which the airbag ( 16 ) is fixed by means of a tensioning device ( 24 ) which is attached to the housing ( 12 ), wherein the fixation ( 14 ) is sewn to the housing ( 12 ).
