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.

Gas generator

The invention relates inter alia to a gas generator () for generating a driving gas for a vehicle safety device, wherein the gas generator has an ignition device () and propellant () which generates gas after being ignited by the ignition device (). It is provided according to the invention that the gas generator () has a tube (), to one tube end () of which the ignition device () is fixed by means of a moulded-in or moulded-on injection-moulded body ().

An occupant protection device including a pyrotechnical gas generator and a safety valve operating in a temperature-dependent manner and leading to the outside is connected to the gas generator. A sealing element of the safety valve is formed by a pin that includes a pin head, which is inserted from inside into a hole in a wall of a supply element such that the pin head bears against the inner face of the wall. A pin end, which is located on the outer face of the wall and protrudes outwardly through the hole, is plastically reshaped, so that the cross section of the pin end is larger than the cross section of the hole thereby forming a sealing portion which is larger in cross section than the cross section of the hole.

Occupant protection device comprising safety valve

A seat belt retractor for a safety belt including a seat belt spindle for winding up and unwinding the safety belt and a tensioning drive. The seat belt spindle includes a gas generator, a drive wheel and a supply pipe which connects the gas generator and the drive wheel. A plurality of thrust members are present in the supply pipe which, after triggering the gas generator, are accelerated and indirectly or directly drive the drive wheel for winding up the safety belt. An inertia coupling is arranged between the drive wheel and the seat belt spindle. The inertia coupling comprises coupling elements which, during an acceleration of the drive wheel, pivot outward and are directly or indirectly coupled to the seat belt spindle.
