A gas generator for filling an airbag of a vehicle is provided. The gas generator can be integrated into the vehicle in such a way that it is electrically insulated from the same, and can be directly connected to the electrical ground of the vehicle, especially to a defined ground potential, by means of a separate ground connection. The separate ground connection thus provides an improved ground connection of the gas generator.

What is claimed is: 1. A gas generator for filling an airbag in a vehicle comprising: a gas generator housing, wherein the gas generator housing is electrically insulated with respect to the vehicle on an outer side of the gas generator; an ignition plug operatively connected to the gas generator housing; and a separate ground connection, clamped in between the ignition plug and the gas generator housing such that the separate ground connection comes into electrical contact with the gas generator housing in a non-insulated contact region on the gas generator housing's outer side, wherein the gas generator housing is directly connected to a defined ground potential of the vehicle by the separate ground connection. 2. The gas generator as claimed in claim 1, further comprising: a latching mechanism, wherein the ignition plug is latched onto both the gas generator and the gas generator housing or either the gas generator or the gas generator housing by the latching mechanism. 3. The gas generator as claimed in claim 1, wherein the ground connection has an annular contact region, it being possible for contact to be made between the annular contact region and the gas generator housing. 4. The gas generator as claimed in claim 3, wherein the annular contact region is resilient. 5. The gas generator as claimed in claim 4, wherein the annular contact region is a spring disk. 6. The gas generator as claimed in claim 1, wherein the gas generator housing is electrically insulated on its outer side. 7. The gas generator as claimed in claim 6, wherein the gas generator housing has a coating for electrically insulating it with respect to the vehicle. 8. The gas generator as claimed in claim 1, wherein the gas generator and/or the gas generator housing can be directly connected to the defined ground potential of the vehicle by a plug connection. 9. The gas generator as claimed in claim 8, wherein the plug connection makes electrical contact with an ignition device of the gas generator. 10. The device as claimed in claim 1, wherein the defined ground potential of the vehicle is an electrical pole of a vehicle battery. 11. The device as claimed in claim 10, wherein an electrical line connects the electrical pole of the vehicle battery to the gas generator housing. 12. A device for making electrical contact with a gas generator housing, wherein the gas generator housing is electrically insulated with respect to the vehicle on an outer side of the gas generator, comprising: an ignition plug, and a separate ground connection, clamped between the ignition plug and the gas generator housing such that the separate ground connection is in contact with the gas generator housing in a non-insulated contact region on the gas generator housing's outer side, wherein the separate ground connection directly connects the gas generator housing to a defined ground potential of a vehicle. 13. The device as claimed in claim 12, wherein the ground connection has an annular contact region, it being possible for contact to be made between said contact region and the gas generator housing. 14. The device as claimed in claim 13, wherein the annular contact region is resilient. 15. The device as claimed in claim 13, wherein the annular contact region is a spring disk. 16. The device as claimed in claim 12, wherein the defined ground potential of the vehicle is an electrical pole of a vehicle battery. 17. The device as claimed in claim 16, wherein an electrical line connects the electrical pole of the vehicle battery to the gas generator housing.
