Abstract

Die Erfindung betrifft ein mikroelektronisch-pyrotechnisches Bauteil (10), insbesondere zur Verwendung in einer Sicherheitseinrichtung für Fahrzeuge wie Anzünder fiir Gasgeneratoren oder Gurtstraffer. Das Bauteil (10) weist einen Kern (12) aus einem explosionsfähigen Material, einen das explosionsfähige Material an den Seitenflächen des Kerns umgebenden Mantel (14) aus einem massiven Halbleitermaterial und ein zwischen elektrischen Kontaktflächen (20) an einer der Stirnseiten (16) des Kerns angeordnetes Zündelement (18) auf. Das explosionsfähige Material ist aus einem porösen Brennstoff und einem in den porösen Brennstoff eingebrachten Oxidator gebildet. Der poröse Brennstoff und das massive Halbleitermaterial sind stoffgleich.

The invention relates to a microelectronic-pyrotechnic component (10), in particular for use in a safety device for vehicles such as igniters for gas generators or belt tensioners. The component (10) has a core (12) made of an explosive material, a jacket (14) made of a solid semiconductor material surrounding the explosive material on the side surfaces of the core and a between electrical contact surfaces (20) on one of the end faces (16) of the Core arranged ignition element (18). The explosive material is formed from a porous fuel and an oxidizer introduced into the porous fuel. The porous fuel and the solid semiconductor material are the same material.
