Abstract
The electropyrotechnic igniter ( ) comprises a body divided into a downstream chamber and an upstream chamber by a discoid metal piece ( ), the downstream chamber containing a resistive heating element ( ), a pyrotechnic initiating composition ( ) and a pyrotechnic ignition composition ( ), and the upstream chamber containing a rectangular electronic card ( ) extended by three external metal pins ( to ), on which electronic card conducting tracks are provided. Two metal connection pins ( ) pass through the discoid metal piece ( ) and connect the said conducting tracks to the resistive heating element ( ). A means of intercommunicating and of triggering a train of specific electric pulses as well as a means of storing electrical energy are connected to the conducting tracks. This igniter is more especially intended to be used in motor-vehicle safety, especially for constituting the device for igniting a gas generator associated with an airbag.
