1. A gas generator, comprising: a housing that defines an inner space of the gas generator and includes an inside facing the inner space;a filter fastened in the housing for filtering gases that the gas generator is configured to generate, wherein the filter includes an outside;an outflow opening through which gas generated in the inner space is configured to flow into an outer space surrounding the housing, wherein the outflow opening is delimited by a boundary region;a sealing part for sealing the outflow opening; anda throttle having a wall,wherein a part of the gas generator is inserted into a recess of the filter for fastening the filter in the housing,wherein the part is configured and provided to widen the filter so that the filter is pressed against the housing for fastening the filter in the housing,wherein said part of the gas generator is formed as a bolt that protrudes from the throttle,wherein the bolt broadens the filter, andwherein the outside of the filter, when the bolt is not inserted into the recess, is in the inner space having play with respect to the inside, and wherein the outside of the filter is pressed against the inside of the housing and simultaneously a circulating boundary region of the wall of the throttle is pressed against the sealing and seals the outflow opening, when the bolt is inserted into the recess. 2. The gas generator as claimed in claim 1, wherein the filter encompasses the part of the gas generator. 3. The gas generator as claimed in claim 1, wherein the throttle is arranged in the housing. 4. The gas generator as claimed in claim 3, wherein the bolt is integrally formed with the throttle. 5. The gas generator as claimed in claim 1, wherein the housing extends along an extension direction. 6. The gas generator as claimed in claim 5, wherein the bolt protrudes along the extension direction from the throttle. 7. The gas generator as claimed in claim 6, wherein the housing is formed at least in sections as a hollow cylinder having a cylinder axis coinciding with the extension direction. 8. The gas generator as claimed in claim 5, wherein the filter surrounds the bolt in a plane running across the extension direction. 9. The gas generator as claimed in claim 1, wherein the recess is formed as a through-opening. 10. The gas generator as claimed in claim 9, wherein the through-opening aligns with the extension direction. 11. The gas generator as claimed in claim 1, wherein the filter is formed at least in sections as a hollow cylinder. 12. The gas generator as claimed in claim 11, wherein the hollow cylinder of the filter comprises a cylinder axis, which coincides with a cylinder axis of the housing. 13. A method for producing a gas generator, comprising the steps of: providing a housing that defines an inner space of the gas generator and includes an inside facing the inner space;arranging a filter in the housing for filtering gases that the gas generator is configured to generate, wherein the filter includes an outside;providing an outflow through which gas generated in the inner space is configured to flow into an outer space surrounding the housing, wherein the outflow opening is delimited by a boundary region;providing a sealing part for sealing the outflow opening; andproviding a throttle having a wall,wherein a part of the gas generator is inserted into a recess of the filter in order to fix the filter in the housing,wherein the part of the gas generator is inserted into said recess along an extension direction of the housing for fixing the filter in the housing, so that the filter widens across said extension direction and pushes against an inside of the housing facing the filter,wherein the part of the gas generator is formed as a bolt that protrudes from the throttle,wherein the bolt broadens the filter, andwherein the outside of the filter, when the bolt is not inserted into the recess, is in the inner space having play with respect to the inside, and wherein the outside of the filter is pressed against the inside of the housing and simultaneously a circulating boundary region of the wall of the throttle is pressed against the sealing and seals the outflow opening, when the bolt is inserted into the recess. 14. The method as claimed in claim 13, wherein the throttle is arranged in the housing.
