    摘要： To prevent spurious operation of a controlled operating element (12), typically a safety element which can be irreversibly triggered, such as a trigger or firing cartridge of a passenger restraint airbag, while providing for reliable operation in case of a crash of a vehicle in which the airbag is installed, a control signal is derived from a computer (10) processing input signals. The transmission of the control signals from the computer (10) to the operating element (12) is through a time delay stage (30) which has a time delay of sufficient length to permit the computer to correct, if necessary, signals from its output (16) and to carry out tests on the output signals from the computer apparatus. An evaluation circuit (18) continuously compares the output signals with check values. The check values may be derived from, for example a second computer similar to the computer, or from stored representative values. If the comparison indicates coincidence, the operating control signal from the computer is transmitted to the operating element (12). If, however, e.g. due to extraneous disturbances, a deviation between the test samples and the signals derived from the output (16) of the computer indicates a deviation, transmission of the control signals from the computer (10) to the operating element (12) is prevented, and the computer is controlled to repeat its computation, or part of a computation cycle.

    摘要： A voltage supply circuit has an energy reserve, which is charged by a voltage transformer, and a comparator circuit, which controls switching circuit components. When the supply voltage is at its nominal value, a first switching circuit component is closed, with the result, that the energy reserve is operated in open circuit and is charged by the voltage transformer. When the supply voltage drops below a threshold, the comparator circuit opens the first switching circuit component and closes a second switching circuit component with the result that, at this point, the charged energy reserve is available for the voltage supply to the circuit configuration normally supplied with voltage from the supply voltage and the voltage transformer is disconnected from the supply voltage.

    摘要： In an evaluation process for output signals of an acceleration-sensitive sensor in restraint systems for vehicle occupants, the output signals of the sensor are picked up and evaluated periodically. In a normal, uncritical operating state the evaluation occurs after relatively long intervals of time. If indications suggest a critical operating state, that is, an accident, however the evaluation of the output signals of the sensor occurs at shorter intervals of time.

    摘要： To permit rapid checking of possible malfunctions or erroneous computations in data processing cycles, in which a plurality of computer units carry out processing of data, especially to supervise and control safety apparatus, each one of the units generate intermediate information data at predetermined time intervals, which intermediate information data are transmitted to each one of the other units. The so-received intermediate information data are buffer-stored and compared in all the units with locally generated check data. If the comparison indicates coincidence, computation is continued through subsequent processing cycles; if an error is detected, at least that computer unit which processes the data erroneously is reset to repeat at least the preceding computation cycle, and the unit which detected the error is placed into a "set-and-hold" mode. The intermediate information data may be derived, for example, in form of a quotient of a beginning and terminal address; additionally, the time of arrival of the intermediate information data can be checked against a time marker, thereby detecting and providing for correction of both computation as well as timing errors.

    摘要： A safety device for vehicle occupants has an operational voltage source, typically the vehicle's battery, and a storage device for electrical energy, typically a capacitor. Several tripping devices, typically ignition tablets, are coupled to the storage device and/or the operational voltage source, for actuating inertial restraining devices, such as airbags, belt tighteners or the like. If the storage device fails, each tripping device is connected for a specified period of time to the operational voltage source by a respective switch. Each switch is triggered by an evaluating device. Therefore, if the storage device fails, as long as the operational voltage source is connected to the safety device, each tripping device and, therefore, inertial restraining device can be actuated.

    摘要： A method of actuating a safety device for vehicle occupants, wherein the safety device has several tripping devices coupled to a capacitor and to passenger restraint devices, such as air bags, seat belts, or the like. The energy supplied by the capacitor to a tripping device is measured upon actuation of that device. If the energy supplied exceeds a predetermined limit, the flow of electric current from the capacitor to the respective tripping device is interrupted. Thus, if an actuated tripping device shunts, the energy of the capacitor is not drained by the shunt, and the capacitor maintains an energy level sufficient to actuate the other tripping devices.
