21 Jun 1990TL;DR: In this paper, a two-stage gas generator with a perforated bulkhead positioned between the first and second stages is described. But the authors focus on the second stage and do not consider the first stage.
Abstract: An impact extruded perforated aluminum housing contains a two-stage gas generator having a perforated bulkhead positioned between the stages. Each stage includes a combustion chamber having an igniter and pyrotechnic charge therein with cooling and filter screens surrounding the combustion chamber. The igniter of the first stage is fired by a squib responsively to an external electrical signal. A rupturable barrier and a ball valve associated with the bulkhead control the flow of gas through the bulkhead and provide mechanical timing for ignition delay in the firing of the second stage after the first stage has been fired, and also provide pressure control after ignition of both stages to prevent repressurizing the first stage. A rupturable foil barrier surrounding the combustion chamber in the first stage promotes a rapid rise in pressure therein and thus breakout sooner therefrom of gas to an airbag to be inflated. A rupturable foil barrier surrounds the cooling and filter screens in the second stage and delays the breakout of gas therefrom to the airbag as the pressure rises, the rate of which pressure rise is less than that at which the pressure in the first stage rises. The thickness of the foil barrier surrounding the combustion and filter screens is selected to be sufficiently less than that of the foil barrier surrounding the first stage combustion chamber so as to achieve substantial equalization of pressure in the first and second stages.

TL;DR: In this paper, an orientationless squib connector assembly for automotive air bag assemblies is described, where a single initiator pin is provided axially aligned within a squib socket.
Abstract: An orientationless squib connector assembly for automotive air bag assemblies is disclosed. A single initiator pin is provided axially aligned within a squib socket. An annular ground plate surrounds the initiator pin near the base of the socket. An associated connector includes a first, axially located terminal for electrical contact with the initiator pin and a second terminal comprising a depending beam radially aligned with the first terminal for electrically contacting the ground plate at any rotational orientation of the connector with respect to the socket. Eliminating a required rotational orientation of the connector simplifies its manufacture and assembly and its incorporation into a vehicle. Preferably, the entering wires are also axially aligned with the first and second terminals.

28 Jun 1990TL;DR: A vehicle inflatable crash protection bag inflator as discussed by the authors is composed of two structural components, which are welded together by only two welded joints to define an inner or combustion chamber containing gas generant material and an outer or diffuser chamber.
Abstract: A vehicle inflatable crash protection bag inflator. the inflator housing comprises two structural components (14, 16) which are welded together by only two welded joints (18, 20) to define an inner or combustion chamber (26) containing gas generant material (56) and an outer or diffuser chamber (32). An igniter tube (36) is disposed in the combustion chamber free of attachment to one of the structural components (16) and is press fit or otherwise suitably attached to a mounting post (34) on the other structural component (14). The igniter tube is perforated and wrapped with a foil (52) whereby the igniter material (50) is disposed in direct contact with a squib (44) so as to better ensure ignition thereof. Alternatively, the igniter tube and igniter material may be eliminated and the gas generant material disposed in direct closely surrounding relation to the squib. The housing is composed of aluminum, and the inflator has a minimum weight and size.

22 Oct 1992TL;DR: An electrically actuated igniter squib is formed by welding a cup containing a pyrotechnic material to a header inserted in the cup, thus forming a hermetic seal.
Abstract: An electrically actuated igniter squib is formed by welding a cup containing a pyrotechnic material to a header inserted in the cup, thus forming a hermetic seal. The diameter of the header exceeds the diameter of the cup and the two are joined by forcing, under pressure, the header into the cup to achieve a tight readily welded joint.

3 Apr 1992TL;DR: 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 as discussed by the authors.
Abstract: 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.
