A vehicle airbag device includes: an inflator configured to generate gas when a first squib and a second squib are fired, respectively; an airbag including a main bag portion configured to inflate and deploy between an occupant seated in a passenger seat and an instrument panel and between the occupant and a windshield when the gas generated by the inflator is supplied into the airbag, and a center bag portion configured to project between the passenger seat and a driver seat from the main bag portion; and a controlling portion configured to control the inflator such that, when a head-on collision occurs, the second squib is fired after the first squib is fired, and when an oblique collision occurs, the second squib is fired after the first squib is fired and at a timing earlier than that when the head-on collision occurs.

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.

An electrical assembly includes a support assembly and/or a track assembly. The support assembly may include a first controller and/or a plurality of safety devices. The electrical assembly may include a track assembly and/or a second controller. The first controller and/or the second controller may be configured to control the plurality of safety devices via a conductor of the track assembly. The plurality of safety devices may include a first safety device, a second safety device, and/or a third safety device. The first safety device may include an airbag and/or may be configured to be activated by pyrotechnics. The first safety device may be configured to be activated by a first deployment current pulse. The support assembly may include a first portion that may include a first contact. The track assembly may include a first track that may include the conductor.

A gas generator including a first igniter, a second igniter, a partition wall that partitions inside a housing into a first space that contains a first gas generating agent and a second space that contains a second gas generating agent, and an inner cylindrical member that houses the first igniter and includes a communication portion at a first end portion, the gas generator further including a closing member that closes a third space that is formed between an inner wall surface of the inner cylindrical member and an outer wall surface of the fixing portion and that connects the communication portion with the first space, the closing member being inhibited from deforming due to pressure from a side of the first space and allowing deformation due to pressure from a side of the third space that negates a closed state between the first space and the third space.

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.

An airbag includes a chamber that expands due to gas being introduced at a time of deployment and a non-expanding area that does not expand at the time of deployment, in which the airbag deploys by gas being introduced into the chamber. A first portion inside the chamber that is located around the non-expanding area includes a tip end portion that is closed, and at the time of deployment, the tip end portion applies a load to and becomes in contact with a second portion of the chamber that is located around the non-expanding area and that faces the tip end portion.

In an assembly group comprising a cap of a tubular gas generator and a deflector element that deflects gas flowing out of at least one outflow opening of the cap to at least one discharge opening of the deflector element, a deflection surface of the deflector element is arranged radially outwardly of the outflow opening. At least two securing arms of the deflector element extend through the outflow opening and engage behind an edge defining the outflow opening on an inside in a positive connection with the cap. The cap is fixed firmly to an axial end of the tubular gas generator. Subsequently, the deflector element is slid from an outside of the cap with its securing arms through the outflow opening, the securing arms forming a positive connection with the edge of the outflow opening which fixes the deflector element firmly to the cap.
