摘要： A base body for a metal-sealing material-feedthrough subject to high pressures in an igniter for an airbag or a belt tensioning device. The base body for the metal-sealing material feedthrough is an element formed by a process of cold forming and having a ring-shape or a plate-like shape. The element includes a feedthrough opening extending from a front side of the element towards a rear side of the element. There is a metallurgic section in the element of the base body with structure-lines or flow-lines that are bent due to a reshaping process of the process of cold-forming.

摘要： An apparatus includes a pressure device bonded to the surface of a structure at a bonding location. The vessel comprises an interior space within the vessel and a bonding surface. A bonding agent bonds the bonding surface of the vessel to a surface of the structure. A gas-emitting material is disposed within the interior space of the vessel and an initiator is arranged to activate the gas-emitting material. Upon activation of the gas-emitting material by the initiator, the pressure device produces a localized force that breaks the structure.

摘要： A method of fabricating an opto-pyrotechnic initiator, includes a) forming a body having a cavity in which a pyrotechnic charge is to be received, the body also having an internal passage extending between the cavity containing the pyrotechnic charge and an inlet opening out in an outside face of the body; b) placing a first portion of an optical fiber in the internal passage of the body, with a second portion of the optical fiber extending beyond the inlet of the body, and a glass preform being interposed between the optical fiber and the inlet of the body; and c) applying heat treatment to the glass preform to raise the glass preform to a temperature higher than the melting point of the glass preform so as to form a hermetic sealing element made of glass between the optical fiber and the inlet of the body.

摘要： A gas generator includes at least two functional subassemblies and at least two retention parts. The functional subassemblies each have an axis defining an axial direction and at least one outer dimension in a plane normal to the axial direction. The retention parts are each radially crimped for retaining one of the at least two functional subassemblies on the gas generator. The at least two retention parts are formed on the same part of the gas generator and the at least two functional subassemblies are positioned on the gas generator with a center distance of axes less than or equal to 1.5 times this outer dimension and that each retention part is radially crimped over at least 90% of its periphery.

摘要： A ring-shaped or plate-like element, in particular for a metal-sealing material-feedthrough, for example for devices which are subjected to high pressures, such as igniters for airbags or belt tensioning devices, includes a feedthrough opening, whereby the feedthrough opening is located substantially in the center of the ring-shaped or plate-like element and whereby the ring-shaped or plate-like element has a thickness. The ring-shaped or plate-like element has a relief region in the area of the feedthrough opening. Further, the ring-shaped or plate-like element in the relief region has at least one thickness which is reduced by the height of the relief region and which is selected so that the feedthrough opening can be punched out of the ring-shaped or plate like element having the reducing thickness.

摘要： A gas-impermeable sealer element (24, 124) for a detonator or other explosive initiation device includes a non-reactive sleeve (26, 126) having a channel (28, 128) formed therein. A reactive material strip (30, 130) is sealed within the channel for transmission of an explosive's initiation signal through the sealer element (24, 124), either alone or in cooperation with transfer charges located at the input and/or output end of the non-reactive sleeve (26, 126). The reactive material strip (30, 130) comprises a reactive metal wire or other substrate (34) having on one or both sides thereof a layer of reactive material (30, 130, 36), either reactive metal foils which react exothermically when ignited, or a deposited fuel-oxidizer reactive material. The reactive materials, upon being energized, react exothermically in the absence of atmospheric oxygen or other extraneous oxidizer and so may be encapsulated, sealed or otherwise isolated from the atmosphere in use.

摘要： The invention relates to an electrical initiator which can be used with an automobile air bag or seat belt pretensioner. The initiator comprises a header, a cup, conducting pins, epoxy pin seals, a bridgewire, a primer, and an output charge. The header and the cup are composed of an insulating dielectric material capable of being ultrasonically welded together. The header secures the pins. Each pin is electrically conductive and each is formed with a buttress knurl to form a seal when each pin is inserted into the header. Additionally, the pins are further sealed to the header by an epoxy sealant. The bridgewire connects the pins together on one side of the header. An electrical signal through the bridgewire generates heat igniting the primer. Primer reacts with the output charge that in turn ignites a solid gas generant that produces gas that fills air bags or activates the gas generator that drives seat belt pretensioners. The primer contacts the bridgewire. The output charge contacts the primer. The output charge is in the cup, and the cup is ultrasonically welded to the header to provide, along with the pin seals, an environmentally secure seal.
