    摘要: Circuit arrangement for triggering a vehicle passenger protection system, having a plurality of triggers (ZP1, ZP2, ZP3), through which (ZP1, ZP2, ZP3) in the event of a sufficiently serious accident a current impulse is conducted in each case, which for its part is intended to trigger the protection, one or more triggering switches (SS in FIGS. 1 and 2), the switching path of which (SS) in each case is non-conductive before the accident, and in the event of a sufficiently serious accident makes the transition to its conductive state and thus causes the current impulse through the triggers (ZP1, ZP2, ZP3), a plurality of current branches (ZP1/C2, ZP2/C5, ZP3/C9), which in each case contain at least one of the triggers, for example a primer capsule (ZP1, ZP2, ZP3), and a capacitor (C2, C5, C9), and a parallel circuit which is formed by the parallel circuit of the current branches (ZP1/C2, ZP2/C5, ZP3/C9). Before the accident the capacitor (C2, C5, C9) of each of the current branches (ZP1/C2, ZP2/C5, ZP3/C9) is connected during the journey to a voltage source (VCC30, GND according to FIG. 3 ), and thus is charged before the accident to an ignition voltage (approximately 30 V). The capacitor (C2, C5, C9) of each of the current branches (ZP1/C2, ZP2/C5, ZP3/C9) has both so high a self-capacitance (270.mu.F) and, before the accident, so high an ignition voltage (approximately 30 V), that during the accident it (C2, C5, C9) delivers the current impulse with reliably sufficient energy in each case to trigger the trigger/triggers (ZP1, ZP2, ZP3) of the relevant current branch (ZP1/C2, ZP2/C5, ZP3/C9) despite any additional energy losses (in D2, D 8, D11, Q6, Q9, Q13, Q16, R41, R42, R56).
