An inflator assembly for an airbag safety system that comprises a container having a chamber configured to hold pressurized gases, an igniting assembly for producing exit gases and a diffusing assembly to vent the exit gases. The container is provided with an end closure that is composed of a material having a substantial silicon content. The diffusing assembly includes a diffuser cap and a burst disk. The diffuser cap has a number of apertures formed therein that allow the exit gases to be released when the burst disk ruptures. The igniting assembly is configured such that it may be coupled to the end closure and capable of withstanding a heat treatment process that bonds the igniting assembly, end closure and container together to form a one-piece structure.

Ultra low cost inflator device and method of manufacturing such

An initiator for an inflator of an automotive airbag restraint system includes a housing and a wall dividing the housing into two parts, one for housing a firing element of the initiator, and one for receiving at least one application specific integrated circuit which performs functions of a portion of an electronic control unit. A mounting element is located in the second part of the housing, and at least one application specific integrated circuit is carried by the mounting element. The mounting element and two or more application specific integrated circuits may be provided as a package, in which at least two application specific integrated circuits are mounted in a stacked condition to form an application specific integrated circuit stack. The application specific integrated circuits are configured such that predetermined electrical circuit locations of adjacent ones of the application specific integrated circuits to be interconnected are aligned. The package includes connectors for electrically interconnecting these predetermined electrical circuit locations in adjacent ones of the application specific integrated circuits in the stack.

A resistant initiator for an automobile passenger restraint system which includes a shell casing having an upper chamber and a lower chamber. Contact pins connect the initiator to a mating electrical connector of a vehicle. A metal oxide varistor disposed in the shell casing provides electrostatic discharge and EMI/RFI rotection for the initiator. A glass to metal seal header is formed in the shell casing and includes an integrated circuit for igniting the pyrotechnic material disposed in a charge holder attached to the shell casing.

An autoignition charge for pyrotechnic automotive airbag in inflation devices is provided in the form of a foil of a synthetic polymer or of a metal, having an adhesive on one surface of the foil and an autoignition material on the opposite surface of the foil. Pieces of foil are readily attached to inflator housings at any suitable location and are secured to the housing by the adhesive on one surface of the foil.

Bondable autoignition foil

An initiator with electrostatic discharge protection includes a generally cup-shaped housing having an open end, a quantity of pyrotechnic material in the housing, and a seal for closing the housing open end and encapsulating the pyrotechnic material within the housing. A pair of electrodes in contact with the pyrotechnic material extend through the seal. A zener diode is coupled in electrical circuit between the housing and one of the electrodes to provide a path for electrostatic discharge and to prevent electrostatic discharge from affecting the pyrotechnic material.

An initiator device for an air bag inflator contains fluid fuel which, upon reaction, produces gas used in the inflation of an inflatable safety device for an occupant of a motor vehicle.

Fluid fuel-containing initiator device for an air bag inflator

A device is provided for ignition of a pyrotechnic or hybrid inflator for use in motor vehicles by the input of energy provided by a laser source. The laser energy is conducted through an optical fibre and an optical window in the inflator housing where the ignition of a propellant initiator is triggered. This apparatus eliminates the potential for ignition of the inflator by radio frequency energy or static electricity acting on the electrical squib which is standardly used to ignite an inflator. This design further simplifies the igniter assembly for use in an inflator.

Direct laser ignition of ignition products

A universal squib connector for automobile driver and passenger air bag collision protection systems includes a ferrite bead having two holes in spaced relation with an electric terminal positioned in each hole for making electrical contact with an associated one of the protruding pins of a pin type electric squib. The arrangement enables the use of a single configuration of gas generator and a single configuration of electric initiator or squib for the igniter system of the gas generator while providing EMI/RFI protection and the advantages realizable from both pin type and pig tail type connection of the collision sensor to the input conductors or lead wires to the squib and also the electrical system of the vehicle according to the preferences of individual automobile manufacturers.
