    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: An apparatus for tripping a system for the protection of occupants of a vehicle has a first sensor (10) for sensing the acceleration of the vehicle in its direction of forward motion and a second sensor (12) for sensing the acceleration of the vehicle in a direction transverse to its direction of forward motion. The two sensors are under the control of control means (14,16) which triggers the occupant protection system in dependence upon the signals from the first and second sensors (10,12).

    摘要: The invention relates to a safety system for motor-vehicle occupants, in particular a restraint system, such as an airbag, belt tighteners, etc., which has at least one tripping sensor that exhibits a response time, one processing unit, and one final firing stage for activating the safety system. To protect against spurious tripping, an inhibiting circuit (21) is proposed, which is triggered by the processing unit (2). It cancels an interlock of the final firing stage (5) only after an interlocking enable time (t.sub.v) has elapsed, whereby the interlocking enable time (t.sub.v) is shorter than the response time (t.sub.a) of the tripping sensor (1).

    摘要: An air bag system for protecting the occupants of a motor vehicle in the event of a collision has a plurality of firing circuits comprising air bag igniters (3a,3b,3c) in series with respective power transistors (T.sub.1,T.sub.2,T.sub.3) which can be triggered in the event of an accident to inflate a corresponding plurality of air bags. A single energy storage capacitor (E) is connected to all of the firing circuits for supplying energy to activate the bag igniters over the upper common power stage (7) in the event that there is a loss of battery voltage when the system has been actuated. A comparator (9) monitors the voltage drops across respective resistors (R.sub.1,R.sub.2,R.sub.3) in series with the power transistors (T.sub.1,T.sub.2, T.sub.3) and reduces the current through these transistors in the event that an excessive current is detected. Steps are taken to ensure that the period of activation of the current supply to the igniters is limited.

    摘要: An apparatus and method for actuating a safety system for protecting an occupant of a motor vehicle measures the acceleration of the vehicle with a first sensor along a first axis oriented substantially parallel to the forward direction of motion of the vehicle. The acceleration of the vehicle is also measured with a second sensor along a second axis oriented at an angle relative to the first axis. The acceleration signal generated by the first sensor is evaluated by an analog processor and the acceleration signal generated by the second sensor is evaluated by a digital processor. The safety system is then actuated based upon both the analog and digital evaluations.
