    摘要: A magnetic impact sensor for motor vehicles with a safety system such as an airbag or belt tensioner for an occupant restraint system, has a circuit breaker arranged in an electrical trigger circuit of the safety system for inflating the airbag or tightening the belt by closing the trigger circuit in response to an acceleration or deceleration effective beyond a prescribed time duration. For this purpose a magnet in combination with specially shaped pole pieces forms two magnetic circuits the magnetic conductances of which are influenced by the position of a ferromagnetic ball that moves in response to an impact relative to the pole pieces to thereby open or close the circuit breaker. Normally, in the absence of an impact the ball is in a first position that keeps the circuit breaker open. When an impact occurs the ball moves into a second position to close the circuit breaker and thus the trigger circuit.

    摘要: The device for visibility measurement is designed primarily for use in motor vehicles. A light emitter is arranged inside the driver's compartment preferably on the rear view mirror in front of the windshield. The light emitter generates light pulses or flashes radiating through the windshield. The light scattered back due to soiling on the inside and outside of the windshield or in scatter zones, formed by fog or smoke or the like, in front of the windshield, impinges a light sensor, preferably likewise arranged on the rear view mirror inside the driver's compartment. By utilizing light pulses of various wavelengths and processing of the output signals of the light sensor in predetermined or predeterminable time windows or intervals, not only the respective visibility but also the type of viewing impairment can be determined.

    摘要: A goniometric device for measuring an angle such as the angle of rotation of the steering wheel in a motor vehicle is useful for providing a backlash-free reduction ratio of the angular movement to be measured. For this purpose an elastic torque rod is used to one end of which the angular movement is applied and the other end of which is rigidly fixed. The angular movement of a tap is taken off at a tap location between the two ends. The reduction ratio depends on the ratio between the two distances from the tap to both ends of the torque rod.

    摘要: The invention relates to an ignition unit (1) suitable for triggering an active system, such as an airbag or safety belt. The ignition unit comprises an ignition charge (7) located in a housing (2), which can be fired by means of an ignition bridge (6) positioned on a support element (5), as well as at least one contact pin (13a, 13b, 13c) which protrudes from the housing (2) and via an electronic ignition system (9) is electrically connected to the ignition bridge (6). The electronic ignition system (9) is surrounded by an envelope (10) made of a shock-absorbing material. The ignition bridge (6) is not covered by the envelope (10) so that during ignition the pressure exerted on the electronic ignition system (9) is cushioned. This prevents damage to the sensitive electronic components of the electronic ignition system (9) situated on the support element (5).
