An airbag inflator includes a lower pressure vessel supporting an initiator assembly, a booster can centrally mounted in the lower pressure vessel and secured to the initiator assembly, and an energetics canister secured over the booster can such that the energetics canister is positioned radially between the lower pressure vessel and the booster can. An energetics cover encloses a circumferential space between the booster can and the energetics canister. A flow diverter closes the booster can and includes inlet vent openings downstream of the energetics cover. An upper pressure vessel positioned over the flow diverter and engaging the lower pressure vessel includes an exit orifice sealed with a rupturable membrane. A manifold is secured over the upper pressure vessel. The inflator increases combustion efficiency and lowers gaseous effluents.

The airbag device includes an airbag and a gas generator. The gas generator includes a body containing inflation gas and sealed with an unsealable lid, and a discharge portion that includes a housing, an outlet that is formed in the housing and allows outflow of gas to the airbag when the body is unsealed, a piercing pin for unsealing the lid, a spring for moving the pin, a retaining member that retains the spring, and a sliding mechanism that shifts the retaining member to a release position. The sliding mechanism includes a drive source and a connecting member that shifts the retaining member to the release position by a driving force of the drive source. The piercing pin, spring, lid and a portion of the retaining member retaining the spring are housed in the housing. The drive source and connecting member are partitioned from a gas channel inside the housing.

The disclosure relates to a gas generator fora vehicle safety system. The gas generator has a longitudinal axis, an outer housing in the form of a compressed-gas container. In an inoperative state of the gas generator, the housing is filled with compressed gas. The housing is closed at one housing end with a closure element by a welded joint, which extends along the longitudinal axis from the welded joint into the housing. The housing has at least one bead for mechanically relieving the welded joint of load. A bead base of the bead is provided in a region of an axial longitudinal extent of the closure element.

An airbag inflator includes a pressure vessel, an initiator positioned at one end of the pressure vessel, a manifold positioned at an opposite end of the pressure vessel, and a generant holder assembly secured in the pressure vessel adjacent the initiator. The generant holder assembly defines an annular space that is configured to secure a generant. A center of the generant holder assembly is open. The open center allows a pressure wave from the initiator to travel to the outlet burst disk.

The invention relates to a hybrid gas generator (10) which comprises a compressed gas chamber (20) and an igniting unit (30), wherein the compressed gas chamber (20) is closed by a first igniter-side bursting membrane (21) and a second bursting membrane (22). According to the invention, a first, rapidly burning-off pyrotechnic agent (51) and a second pyrotechnic agent (52) burning off slowly in comparison to the first pyrotechnic agent (51) are located in the hybrid gas generator (10), wherein the second bursting membrane (22) is openable by positive pressure which can be generated in the compressed gas chamber (20) and the first pyrotechnic agent (51) is separated from the second pyrotechnic agent (52) in such a manner that the positive pressure in the compressed gas chamber (20) for opening the second bursting membrane (22) can be generated by the first pyrotechnic agent (51).

An ignition device assembly includes an ignition device including an igniter body and an igniter collar member, and a housing including a tubular fixing portion to which the igniter collar member is fixed. The tubular fixing portion includes a crimping fixing portion. The igniter collar member includes a tubular wall portion having a tubular shape, made of metal, and including a connector connection space formed inside, the tubular wall portion being crimped by a crimping fixing portion, an opening end forming portion including a resin region portion and a metal region portion, extending from a tip side of the tubular wall portion and forming an opening end of the connector connection space, and a crimping tip surface opposing region portion. At least a part of the crimping tip surface opposing region portion is formed by the metal region portion.

A gas generator, such as for a safety device in vehicles, comprises a pressure chamber which is filled with compressed gas and which is closed off from an environment outside of the gas generator by a membrane. The compressed gas contains a gaseous oxidant which is composed predominantly of oxygen. The pressure chamber receives a solid fuel, wherein the compressed gas is in direct contact with the fuel before the gas generator is activated. When the gas generator is activated, an igniter separated pressure-tightly from the pressure chamber triggers a conversion of the gaseous oxidant with the solid fuel, with heat being generated. The fuel is in the form of a gas-permeable fuel body made up of one or more fibers, and the molar fraction of the gaseous oxidant in the compressed gas is at least 1.1 times the amount of oxidant required for a stoichiometric conversion of the gas-permeable fuel body. A module and a vehicle safety system comprise such a gas generator.
