Gas generator

A gas generator (10) for generating a driving gas (G) for a vehicle safety device, wherein the gas generator (10) comprises:

• an ignition device (80),
• fuel (70) which, after ignition by the ignition device (80), generates the driving gas (G),
• a tubular or at least partially tubular carrier element (20, 20a), a tube interior of which contains a combustion chamber (60) for the fuel (70), and which has a connection hole (24) for the ignition device (80),
• an injection-molded body (40) which fixes the ignition device (80) in the connection hole (24) and is situated with an inner portion inside the carrier element (20, 20a) and with an outer portion (43) outside the carrier element (20, 20a),
• a supply pipe (30) which is connected to a tube end of the carrier element (20, 20a) and conducts the driving gas (G) out of the combustion chamber (60), and
• a lid (50) which seals the combustion chamber (60) and which, before ignition of the ignition device (80), separates the combustion chamber (60) from the supply pipe (30), characterized in that
• the carrier element (20, 20a) has a drainage hole (26) leading radially towards the outside in the region of the combustion chamber (60), and
• the drainage hole (26) is closed by a closure portion (26) of the injection-molded body (40) and together therewith forms a valve (100) of the gas generator (10) which, in an open state, allows the driving gas (G) to escape radially towards the outside.

• characterized in that
• the connection hole (24), at which the ignition device (80) is fixed by means of an inserted or attached injection-molded body (40), is situated in the outer wall (27) of a tubular portion of the carrier element (20, 20a), and the injection-molded body (40) extends outwardly through the connection hole (24) in an extension direction (E) which is arranged at an angle, in particular a right angle, to the longitudinal direction (L) of the tubular portion of the carrier element (20, 20a).
