A gas bag module, in particular a side gas bag module, for a vehicle occupant protection system, has a gas bag, a gas generator, a housing of which has several outflow openings which are disposed such that the gas generator is in principle thrust-neutral. Further provided is a closure element which, in a standard case of release of the gas bag module, prevents gas from flowing out, at least in one direction, and in the case of fire is at least in sections thermally weakened or destroyed, such that the gas generator blows out gas thrust-neutrally.

The invention claimed is: 1. A gas bag module for a vehicle occupant protection system, comprising a gas bag (28), a gas generator (10), a housing (12) of which has several outflow openings (14) which are disposed such that the gas generator (10) is in principle thrust-neutral, and a closure element which, in a standard case of release of the gas bag module, prevents gas from flowing out, at least in one direction, and in a case of fire is at least in sections one of thermally weakened and thermally destroyed, such that the gas generator (10) blows out gas thrust-neutrally, wherein in the region of the outflow openings (14), the closure element is in direct contact with the housing (12) of the gas generator (10). 2. The gas bag module according to claim 1, wherein the closure element is made of synthetic. 3. The gas bag module according to claim 1, wherein the closure element closes part of the outflow openings (14) so as to be largely gas-tight. 4. A gas bag module for a vehicle occupant protection system, comprising: a gas bag (28), a gas generator (10), a housing (12) of which has several outflow openings (14) which are disposed such that the gas generator (10) is in principle thrust-neutral, and a closure element which, in a standard case of release of the gas bag module, prevents gas from flowing out, at least in one direction, and in a case of fire is at least in sections one of thermally weakened and thermally destroyed, such that the gas generator (10) blows out gas thrust-neutrally, wherein the closure element is a covering plate (16) with at least one integrally formed appendage (17, 18) engaging in at least one outflow opening. 5. The gas bag module according to claim 4, wherein the covering plate (16) has a material of greater thermal stability than the appendage (17, 18). 6. The gas bag module according to claim 4, wherein the appendage (17) engages in an outflow opening (14) of the housing (12). 7. A gas bag module for a vehicle occupant protection system, comprising: a gas bag (28), a gas generator (10), a housing (12) of which has several outflow openings (14) which are disposed such that the gas generator (10) is in principle thrust-neutral, and a closure element which, in a standard case of release of the gas bag module, prevents gas from flowing out, at least in one direction, and in a case of fire is at least in sections one of thermally weakened and destroyed, such that the gas generator (10) blows out gas thrust-neutrally, wherein the gas generator (10), at least in sections, is surrounded by a bracket (20) which in the region of the outflow openings (14) of the housing (12) also has openings (22). 8. The gas bag module according to claim 7, wherein the closure element is disposed between the gas generator (10) and the bracket (20). 9. The gas bag module according to claim 7, wherein the closure element is a covering plate (16) with at least one integrally formed appendage (18) which engages in an opening (22) of the bracket (20). 10. A gas bag module for a vehicle occupant protection system, comprising: a gas bag (28), a gas generator (10), a housing (12) of which has several outflow openings (14) which are disposed such that the gas generator (10) is in principle thrust-neutral, and a closure element which, in a standard case of release of the gas bag module, prevents gas from flowing out, at least in one direction, and in a case of fire is at least in sections one of thermally weakened and thermally destroyed, such that the gas generator (10) blows out gas thrust-neutrally, wherein the closure element comprises at least one fabric layer (24). 11. A gas bag module for a vehicle occupant protection system, comprising a gas bag (28), a gas generator (10), a housing (12) of which has several outflow openings (14) which are disposed such that the gas generator (10) is in principle thrust-neutral, and a closure element which, in a standard case of release of the gas bag module, prevents gas from flowing out, at least in one direction, and in a case of fire is at least in sections one of thermally weakened and destroyed, such that the gas generator (10) blows out gas thrust-neutrally, said closure element comprising at least one fabric layer (24), wherein the fabric layer (24) is part of a fabric tube (26, 34) surrounding the gas generator (10). 12. The gas bag module according to claim 11, wherein at least in the region of the outflow openings (14) the fabric tube (26, 34) does not have any seams (30). 13. The gas bag module according to claim 11, wherein the fabric tube (26, 34) is multi-layered, at least in the region of the closure element. 14. The gas bag module according to claim 11, wherein the fabric tube (26, 34) rests against the gas generator (10) in the region of the closure element and has a significantly greater diameter than the gas generator. 15. The gas bag module according to claim 11, wherein the fabric tube (26, 34) is totally without seams. 16. The gas bag module according to claim 11, wherein the gas generator (10) is surrounded by two fabric tubes (26, 34) of different diameter. 17. A gas bag module for a vehicle occupant protection system, comprising a gas bag (28), a gas generator (10), a housing (12) of which has several outflow openings (14) which are disposed such that the gas generator (10) is in principle thrust-neutral, and a closure element which, in a standard case of release of the gas bag module, prevents gas from flowing out, at least in one direction, and in a case of fire is at least in sections one of thermally weakened and destroyed, such that the gas generator (10) blows out gas thrust-neutrally, wherein in the region of the outflow openings (14), the gas generator (10) is surrounded by a tubular housing (36), a first axial end (38) of which is open, and a second axial end (40) of which is closed at least partially by the closure element. 18.
