A gas generator includes an igniter, a cup-shaped member, and a fixing member. The cup-shaped member accommodating an enhancer agent bursts or melts at the time of activation. The fixing member fixing a filter does not burst and melt even at the time of activation. Ra and Ha satisfy a condition of Ra/Ha 1.00 where Ra represents an inner diameter of a sidewall portion of the cup-shaped member and Ha represents a distance between a top wall portion of the cup-shaped member and the igniter. The sidewall portion includes a first region surrounded by a partition wall portion of the fixing member and a second region not surrounded by the partition wall portion. The partition wall portion has an end portion arranged closer to a top plate portion than the igniter. A gas generating agent is arranged to face the top wall portion, the second region, and the partition wall portion.

The invention describes an igniter support (22) for an igniter unit (20) of a gas generator (10), comprising a first holder element (30) made from a first material and a second holder element (32) made from a second material different from the first material. Both holder elements (30, 32) can be positively coupled to each other. Further, a subassembly (16), a gas generator (10) and a method for manufacturing a gas generator (10) are described.

The two holder elements (30, 32) can be positively coupled to each other, especially can be at least partially positively nested. Further, a subassembly (16), a gas generator (10) as well as a method for manufacturing a gas generator (10) are described.

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.

A passenger protection apparatus for a vehicle includes an inflator and an airbag body. The inflator is configured to generate gas upon receiving a predetermined actuating signal. The airbag body is folded and configured to deploy by supplying the gas from the inflator to the airbag body. The airbag body includes a predetermined area on which adhesive is applied. An adhesive force of the adhesive is exerted by heat of the gas from the inflator during deployment of the airbag body, so that the predetermined area adheres to an adherend at a desired position.

The airbag body is folded and configured to deploy by supplying the gas from the inflator to the airbag body. The airbag body includes an predetermined area on which adhesive is applied. The predetermined area adheres to an adherend when the airbag body is deployed. When the airbag body is not deployed, the airbag body is stored in a deflated and bound state, and a surface facing the predetermined area when the airbag body is stored is a peel-off surface on which an adhesive force of the adhesive is lost.

The present disclosure relates to a gas generator comprising a housing, an igniter and a pyrotechnic charge via which gas for filling a gasbag can be provided, wherein the gas generator is free from stored pressurized gas in the idle state, characterized in that each possible diffusion path out of the internal chamber of the housing is sealed relative to the environment of the gas generator by means of a weld seam. The present disclosure also relates to a method for leak testing a pyrotechnic gas generator of this type, wherein, before the gas generator is welded against diffusion, a test amount of helium is introduced into the housing and, in a subsequent leak testing step, a measurement is carried out to determine whether helium is passing out of the housing.

A metal-fixing material feedthrough for at least one of an airbag igniter or a belt pre-tensioner includes a main body having a through opening formed therein and at least one metal pin fused into the through opening in a vitreous or glass ceramic fixing material. A surface of the vitreous or glass ceramic fixing material is a freely fused surface and lies in a same plane as an end face of the at least one metal pin.

A propellant cage (10) for a tubular inflator (100), especially for a tubular inflator (100) of an airbag module, for forming a propellant chamber (14) and a flow passage (15) of the tubular inflator (100). The propellant cage (10) is in the form of a propellant cage spiral spring (11) having a gas inlet-side end (12) and a gas outlet-side end (13), the gas inlet-side end (12) having a smaller cross-section than the gas outlet-side end (13).

An actuator assembly that includes an actuator device. The actuator device includes a tubular housing with a first end and a second end, the tubular housing defining a storage chamber containing a pyrotechnic material to produce gas. At least one electrical connection is coupled to the first end, the electrical connection in reaction initiating communication with the pyrotechnic material. An actuator housing that partially encompasses the tubular housing, wherein an outer surface of the actuator housing comprises a hexagon shaped portion that extends along a longitudinal direction of the actuator housing. An assembly housing at least partially encompasses the actuator device, wherein an inner surface of the assembly housing comprises an engaging surface portion that extends along a longitudinal direction of the assembly housing that corresponds to and slidably engages with the hexagon shaped portion of the actuator housing.
