Abstract

The invention relates, among other things, to a gas generator for generating a driving gas for a vehicle safety device, wherein the gas generator comprises: an ignition device; fuel which, after ignition using the ignition device, generates the driving gas; an at least partially tubular carrier element, in the tube interior of which a combustion chamber for the fuel is located; an injection-moulded body which fixes the ignition device in the connection hole and is located with an inner portion inside the carrier element and with an outer portion outside the carrier element; a feed pipe which is connected to a pipe end of the carrier element and which conveys the driving gas out of the combustion chamber; and a lid sealing the combustion chamber.
