    • A piezoresistive sensor arrangement, e.g. for a passenger protection system of a vehicle, with a resistance circuit (RS1/RS2, RS3/RS4) of at least four resistors, two of which form a series mounting (RS1/RS2, RS3/RS4) with a tapping (A1, A2) between them. The first of the two external connections of the series mountings are interconnected (E11 with E21). The sensor has at least one single piezoresistive resistor to generate the output signal (Us) of the sensor arrangement, whereby it either electrically represents the resistance circuit, when at least one of these four resistors is a piezoresistive resistor, or it is supplemented by one or more resistors in addition to the resistance circuit. The interconnected first (E11, E21) external connections of the series mountings are connected to the output of an input differential amplifier (V1), the first output (+) of which is connected to a reference voltage (Uref). The second external connection (E21) of the first (RS1/RS2) of the two series mountings is connected to the second input (-) of the input differential amplifier (V1). The first series mounting (RS1/RS2) is bridged with a temperature-insensitive resistor (Rtk).

    • A triggering circuit for a crash-sensor-controlled (A) protective system for the passengers in a vehicle, with an ignition capacitor (C) charged to a voltage (U) by the vehicle's electric system (N) before an accident as the power source to ignite a gas generator (Z), i.e. to ignite an explosive charge or a detonator (Z) of said charge and with at least one crash sensor (A) which detects the occurrence of the sensor reading triggering ignition and controls the ignition of the gas generator by the discharge of the ignition capacitor via one or more contacts (S, T). Several ignition capacitors are commutatable; they are connected in parallel before an accident and charged to the voltage of the vehicle's electrical system and, on the occurrence of an accident, are low-ohmically connected in series via a single contact in such a way that, at least at the start of ignition, the total voltage (V) across this series circuit is greater than the individual capacitor voltages. The total voltage can be supplied low-ohmically to the gas generator via at least a single contact.
