An igniter for a gas generator comprises a pole body (14) having at least one connection pin (16, 18), a retaining ring (20) and an insulation ring (22), wherein the insulation ring (22) spaces apart the at least one connection pin (16, 18) from the retaining ring (20) and electrically insulates it relative to the same. The retaining ring (20) consists of a metal and the insulation ring (22) consists of a plastic. In order to produce an igniter (10) for a gas generator at least one connection pin (16, 18), a retaining ring (20) and an insulation ring (22) are provided, the connection pin (16, 18), the insulation ring (22) and the retaining ring (20) are fitted inside one another in such a way that the connection pin (16, 18) is surrounded by the insulation ring (22) and the insulation ring (22) is surrounded by the retaining ring (20), and the retaining ring (20), the insulation ring (22) and the connection pin (16, 18) are compressed in a compression step in which at least the retaining ring (20) is deformed and the retaining ring (20), the insulation ring (22) and the connection pin (16, 18) are connected to one another securely and without play.

The disclosure relates to a gas generator—for a vehicle safety system, comprising an ignition unit including a holding element, an igniter and a base. The base is formed by one single plastic injection molding such that the igniter is embedded in the base and the base is injection-molded to the holding element. A membrane which hermetically seals an inner first opening of the holding element is provided.

An initiator head may include a housing extending in an axial direction, a circuit board provided in an interior space of the housing, a line-in terminal provided on a first side of the housing in the axial direction and accessible from an exterior of the housing, and a fuse displaced from the circuit board in the axial direction. A thickness direction of the circuit board may be substantially parallel with the axial direction. The line-in terminal may be in electrical communication with the circuit board. The fuse may be in electrical communication with the circuit board. The circuit board may be configured to activate the fuse in response to a control signal received at the line-in terminal.

An initiator head assembly may include a body and an electrical contact component positioned proximal to the body. The body may include a head extending from a base, and a platform extending from the head, and the body may be injection molded as a unitary component. The electrical contact component may include a line-in portion positioned proximal to the platform and a ground portion positioned proximal to the head. The electrical contact component may be formed integrally with the body such that it is anchored in a fixed position in the body. An initiator for a perforating gun assembly may include the initiator head assembly and a shell coupled to the initiator head assembly.

Disclosed is a magazine apparatus including a first magazine and a second magazine. The first magazine is configured for holding, carrying and dispensing first initiation device components. The second magazine is configured for holding, carrying and dispensing second initiation device components. The first magazine and the second magazine are configured to dispense the first initiation device components and the second initiation device components in a corresponding manner such that a dispensed one of the first initiation device components and a correspondingly dispensed one of the second initiation device components can be assembled together to form a structurally complete, unified initiation device for loading into a borehole.

A sealing structure of a sealed container includes, a metallic cylindrical container having an opening, and a metallic closing member that closes the opening. The metallic closing member has an outer surface opposing an inner wall surface of the metallic cylindrical container, and the outer surface of the metallic closing member is one of plated with metal and covered with thermoplastic resin. The metallic closing member seals the opening of the metallic cylindrical container by one of melted metal and melted thermoplastic resin, and the one of melted metal and melted thermoplastic resin is a material different from a material of the metallic cylindrical container and the metallic closing member.

The invention relates to an ignition capsule for a gas generator of an occupant restraint system in a motor vehicle, in particular for the gas generator of an inflatable airbag, said ignition capsule comprising means for supporting extremely high pressures during ignition.
