A device associated with a method for preventing manipulation establishes a chain of tamperproof evidence for the non-use of seat belts and time periods thereof during a journey and in a crash or multi-crash and saves all the relevant and accident data in a blackbox and/or storage medium of the transport system. In addition, indicators verify the non-use of seat belts. Consequently, the car-aeroplane manufacturer or the airline is spared lawsuits, compensatory damages and/or medical -expenses. In order to determine the service-life and worn parts of restraint-systems the device registers the numbers of seat-belt usages, real belt protractions and blockings. In excess of any predetermined service-life a warning light flashes and/or appears on a multi-info display to replace the worn parts of restraint-systems and/or an appropriate spoken message is issued. Courts can thus determine who is responsible for the failure of the restraint system/s in the accident.
