A gas generator, includes an igniter, a housing provided with a gas discharge port, and including a combustion chamber to burn a gas generating agent, the igniter being shifted from a center of a cluster of the gas generating agent, an isolating part surrounding at least a portion of the cluster of the gas generating agent, and forms, between the isolating part and a predetermined area, a gas flow space serving and a plurality of communicating parts that are provided in the isolating part and connect the combustion chamber and the gas flow space, a portion of the plurality of communicating parts allowing a combustion product generated by combustion of the gas generating agent disposed proximal to the igniter to flow into the gas flow space, and another portion of the plurality of communicating parts allowing a combustion product flowing through the gas flow space to flow out toward the gas generating agent disposed distal to the igniter.

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.

Electrical ignition of electrically operated propellant in a gas generation system provides an ignition condition at an ignition surface between a pair of electrodes that satisfies three criteria of a current density J that exhibits a decreasing gradient along an axis normal to an ignition surface, is substantially constant across the ignition surface and exceeds an ignition threshold at the ignition surface. These criteria may be satisfied by one or more of an angled electrode configuration, a segmented electrode configuration or an additive to the electrically operated propellant that modifies its conductivity. These configurations improve burn rate control and consumption of the available propellant and are scalable to greater propellant mass to support larger gas generation systems.

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.

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 a wiring harness (10) for an airbag module of a vehicle occupant safety system, particularly for a driver's airbag module, having a connector (11) for connecting to a pyrotechnic igniter of the airbag module, at least one module connecting cable (12) connected to the connector (11) for connecting the connector (11) to a vehicle wiring harness, and at least one actuator unit (13) having a pyrotechnic actuator (17) and an actuator connecting cable (14) which is formed integrally with the actuator unit (13) and is connected to the connector (11). The invention further relates to an airbag module, vehicle cabling and a vehicle occupant safety system having a wiring harness of this kind and to a method of production.

A dual stage inflator includes a housing defining an internal cavity including a combustion chamber. The combustion chamber includes a first portion having a first gas generant material separated from a second portion having a second gas generant material. A gas generant retaining wall is disposed in the housing. A first stage ignition device is disposed in the first portion of the combustion chamber. A second stage ignition device is disposed in the second portion of the combustion chamber. A lid normally closes the second portion of the combustion chamber and is spaced from the gas generant retaining wall. The lid is moveable to an open position opening the second portion of the internal cavity to release combustion gas and abutting the gas generant retaining wall in response to an increase of pressure within the second portion of the combustion chamber. An outer side of the lid and the adjacent side of the gas generant retaining wall are cooperatively configured to allow a flow of combustion gas between the gas generant retaining wall and the lid when the lid abuts the gas generant retaining wall in the open position.

A vehicle airbag system includes an airbag module, a seat detector, and an electronic controller. The airbag module has an airbag that is configured to be movably mounted to a vehicle roof structure. The seat detector detects a position of a vehicle seat. The electronic controller is in communication with the airbag module and the seat detector. The controller controls the airbag module to inflate the airbag in a predetermined direction based on detected position of the vehicle seat by the seat detector.

An igniter holding structure includes, an igniter provided with an ignition portion and a conductive pin, a first resin portion provided between the igniter and an attachment portion and holds the igniter such that the ignition portion and a distal end of the conductive pin are located opposite each other, and a second resin portion provided in a circumferential wall portion of the attachment portion and forming a connector insertion portion on an inner side of the circumferential wall portion, the connector insertion portion being a space into which a connector connected to the conductive pin can be inserted and the second resin portion being provided separated from the first resin portion on the inner side of the circumferential wall portion in a manner that an exposed surface, which is made of metal and exposed to the connector insertion portion, is formed in the circumferential wall portion.
