Abstract: In a method for operating a safety system of a motor vehicle, a corresponding safety system, and a motor vehicle equipped with such safety system, status signals from several sensor devices are captured by the safety system, wherein the status signals indicate respective status change of a functional unit of the motor vehicle. Thereafter, a chronological order of the status changes is determined and evaluated to detect a consistency or an inconsistency with the proper application of a seat belt of the motor vehicle. If an inconsistency is detected and it persists over a predetermined period of time, a control signal is transmitted by the safety system to a safety device of the motor vehicle.

Abstract: Apparatus for detecting a proper wearing status of a safety belt of a safety belt assembly in a motor vehicle includes a sensor device which is at least partially disposed in or on the safety belt and configured to output a sensor value as a function of a dependency on a disposition of the safety belt. An evaluation device determines in response to the sensor value output by the sensor device, whether an occupant of the motor vehicle properly wears the safety belt.
