International Classification:

F42B 318
F42C 1912

US Classification:

1022021

Abstract:

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. In some embodiments, the initiator also includes a director can. 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 and the interference fit of the pin to the header. The bridgewire connects the pins together on one side of the header. An electrical signal through the bridgewire generates heat igniting the primer.

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.

International Classification:

F42B 318

US Classification:

1022022

Abstract:

A radio frequency attenuating connector includes a secondary coil connected to a load, an electromagnetic shield enclosing the secondary coil and the load, a primary coil, a coupler for detachably coupling the primary coil and the secondary coil, an integrated circuit including a square wave oscillator producing complementary output signals, and first and second switching devices. The first switching device is responsive to one of the complementary output signals for causing a current to flow in one direction through at least a portion of the primary coil during a first half cycle of oscillation, and the second switching device is responsive to another of the complementary output signals for causing a current to flow in an opposite direction through at least a portion of the primary coil. The integrated circuit has an enable feature and includes additional protection circuitry for enhancing the safety of the radio frequency attenuating connector.
