What is claimed is: 1. A gas bag module for a vehicle occupant restraint device, said gas bag module comprising a gas generator and a gas bag with a wall, and a diffuser which surrounds said gas generator and has a cup-shaped section, said cup-shaped section having a filter section comprising at least one fiber, through which filter section gas flows out from said gas generator, wherein said cup-shaped section has an edge provided with a laterally projecting ring-shaped flange, said flange comprising a material formed from said at least one fiber. 2. A gas bag module for a vehicle occupant restraint device, said gas bag module comprising a gas generator, a gas bag having a wall, and a diffuser having a cup-shaped section, said cup-shaped section of said diffuser comprising at least partly a filter material comprising at least one fiber, and forming a filter section through which gas flows out from said gas generator, said diffuser, including said filter section, surrounding said gas generator with a defined spacing. 3. The gas bag module according to claim 2, wherein the defined space between said gas generator and said diffuser is empty such that said diffuser does not contact said gas generator and said filter section does not contact said gas generator, said filter section comprising at least one fiber through which filter section gas from said gas generator flows. 4. The gas bag module according to claim 2, in which said filter section is designed such that it acts as a particle filter for through-flowing gas. 5. The gas bag module according to claim 2, wherein said filter section comprises one of a knitted mesh, knitted fabric, woven fabric and an irregular structure of said at least one fiber. 6. The gas bag module according to claim 2, wherein said cup-shaped section comprises a side wall and a cover, said side wall being formed from a material comprising said at least one fiber. 7. The gas bag module according to claim 2, wherein at least said cup-shaped section comprises a material formed from said at least one fiber. 8. The gas bag module according to claim 2, in which said cup-shaped section is designated as a deformation element capable of being deformed on impact of an occupant's body part. 9. The gas bag module according to claim 2, in which said at least one fiber is a metal wire. 10. The gas bag module according to claim 2, in which said gas generator is held in an elastic bearing so as to be able to oscillate. 11. The gas bag module according to claim 2, wherein said gas generator is a filter-less gas generator. 12. The gas bag module according to claim 2, wherein the defined spacing between said gas generator and said diffuser is at a distance such that said gas generator is able to oscillate unimpeded inside said diffuser. 13. A gas bag module for a vehicle occupant restraint device, said gas bag module comprising a gas generator and a gas bag with a wall, and a diffuser which surrounds said gas generator and has a cup-shaped section, wherein said cup-shaped section is made entirely of a filter material, said filter material comprising at least one fiber. 14. The gas bag module according to claim 13, in which said diffuser is designed such that it acts as a particle filter for through-flowing gas. 15. The gas bag module according to claim 13, wherein said diffuser comprises one of a knitted mesh, knitted fabric, woven fabric and an irregular structure of said at least one fiber. 16. The gas bag module according to claim 13, wherein said cup-shaped section comprises a side wall and a cover. 17. The gas bag module according to claim 13, in which said cup-shaped section is designated as a deformation element capable of being deformed on impact of an occupant's body part. 18. The gas bag module according to claim 13, in which said at least one fiber is a metal wire. 19. The gas bag module according to claim 13, in which said gas generator is held in an elastic bearing so as to be able to oscillate. 20. The gas bag module according to claim 13, wherein said gas generator is a filter-less gas generator.
