    • In a method for tripping a restraint device in a vehicle, coded information signals with status and diagnosis messages are transmitted in both directions between an evaluation device and an ignition device. To avoid the situation where a tripping signal for the restraint device may be delayed in its transmission to the ignition device because the data throughput in the transmission medium is high, the transmission of the information signals is interrupted. Accordingly, the transmission of the information signals in the forward and return directions is controlled by the evaluation device. As a function of a collision signal furnished by a sensor device, the transmission of the information signals is ended by the evaluation device, so that the transmission medium between the evaluation device and the ignition device remains free for a possibly ensuing tripping signal.
    • 在用于使车辆中的约束装置跳闸的方法中,具有状态和诊断消息的编码信息信号在评估装置和点火装置之间沿两个方向传送。 为了避免由于传输介质中的数据吞吐量高而使得约束装置的跳闸信号可能被延迟到点火装置的传输的情况,信息信号的传输被中断。 因此,信息信号在正向和返回方向的传输由评估装置控制。 作为由传感器装置提供的碰撞信号的功能,信息信号的传输由评估装置结束,使得评估装置和点火装置之间的传输介质对于可能的随后的跳闸信号保持不变。

    • A triggering circuit for a crash sensor-controlled protective system for the occupant of a vehicle includes a firing capacitor being charged to a capacitor voltage by the electrical system of the vehicle before an accident, as an energy source for firing a gas generator, that is for firing an explosive charge or for firing a firing cap of an explosive charge. At least one crash sensor detects the occurrence of the sensor values that trigger the firing and controls the firing of the gas generator by one or more contacts by discharging the firing capacitor. A plurality of firing capacitors which are provided in a switching-over manner are connected in parallel before an accident and then charged to a capacitor voltage corresponding to the voltage of the electrical system of the vehicle and in the case of an accident are connected in series in a low-impedance manner by at least one single contact in such a way that, at least at the start of firing, the instantaneous total voltage through the series connection is greater than the individual capacitor voltages in themselves. The total voltage can be fed to the gas generator in a low-impedance manner by at least one single contact.
