Abstract

Es wird eine pyrotechnische Zündeinrichtung mit integrierter Elektronikbaugruppe, insbesondere für Insassenschutzeinrichtungen in Kraftfahrzeugen, vorgestellt, die einen Pyrotechnikbereich (A) mit einer pyrotechnischen Wirkmasse (3) und einer elektrisch zündbaren Zündbrücke (1) sowie einen davon getrennten und so vor den Auswirkungen der Zündung geschützten Elektronikbereich mit einer Elektronikbaugruppe aufweist, wobei die Zündbrücke (1) als auch die Elektronikbaugruppe auf einer gemeinsamen Trägeranordnung angeordnet sind, die jedoch Entkopplungsstellen (23), beispielsweise Sollbruchstellen oder Biegestellen aufweist, so daß bei der Zündung der pyrotechnischen Wirkmasse auftretende Kräfte nicht über die Trägeranordnung in den Elektronikbereich weitergegeben bzw. auf vorgegebene Grenzbelastungen begrenzt werden.

Figure 00000001
A pyrotechnic ignition device with an integrated electronic module, in particular for occupant protection devices in motor vehicles, is presented, which has a pyrotechnic area (A) with a pyrotechnic active mass (3) and an electrically ignitable ignition bridge (1) as well as a separate one and thus protects it from the effects of the ignition Electronics area with an electronics module, the ignition bridge (1) and the electronics module are arranged on a common carrier arrangement, but which has decoupling points (23), for example predetermined breaking points or bending points, so that forces occurring during the ignition of the pyrotechnic active mass do not pass through the carrier arrangement passed on to the electronics sector or limited to specified limit loads.
