Abstract

Abstract Translated from German Eine Schaltungsanordnung dient zum Auslösen eines Kfz-Airbag-Systems und enthält einen Energiespeicher (1), mindestens einen Auslöseschalter (2, 3, 4, 8, 9) und mindestens zwei parallel geschaltete Serienzweige mit je einem Auslöser (5, 6, 7) für einen Airbag. In jedem Serienzweig liegt ein Kondensator (21, 22, 23), der im Auslösefall die Strommenge begrenzt, um eine sichere Auslösung der weiteren, verzögert wirkenden, Auslöser zu gewährleisten. A circuit arrangement is used to trigger a motor vehicle airbag system and contains an energy store (1), at least one trigger switch (2, 3, 4, 8, 9) and at least two series branches connected in parallel, each with a trigger (5, 6, 7) for an airbag. In each series branch there is a capacitor (21, 22, 23) which, in the event of a trip, limits the amount of current in order to ensure reliable triggering of the further triggers which act with a delay.
