In order that safety systems, such as distress beacon emitters carried on board an aircraft, can be triggered beth in the case of a very short, violent shock or impact and during a longer, but less violent shock or impact, a shock or impact detector is proposed, which takes into account both the amplitude and the duration of a possible shock or impact. This detector comprises an electromagnetic transducer (50), whose coil supplies a pulse signal having an amplitude and duration proportional to the amplitude and to the duration of the shock. An integrator (80) makes it possible to obtain an integrated signal, whose amplitude is proportional both to the amplitude and the duration of the shock. A comparator (82) then makes it possible to control safety systems, if said integrated signal exceeds a preferably regulatable threshold.

Shock detector which can be carried on a vehicle for automatically triggering, in the case of a shock or impact, at least one safety system, said detector comprising a shock transducer able to emit, in the case of a shock, a pulse signal having an amplitude and a duration respectively proportional to the amplitude and duration of the shock, integration means, sensitive to said pulse signal, for supplying an integrated signal having an amplitude which increases with the amplitude and duration of the shock and detection and control means sensitive to said integrated signal for triggering the safety system when the amplitude of said integrated signal exceeds a predetermined threshold; said shock detector further comprising amplification means and shaping means for the pulse signal, interposed between the shock transducer and the integration means; and wherein the pulse signal shaping means incorporate a non-linear amplifier and inverted clipping diodes having calibrated thresholds.
