  • sensors for detecting a collision of the motor vehicle;

    a control unit for analyzing signals of the sensors, which, when recognizing a collision of the motor vehicle, transmits a first signal to a first restraint device comprising a safety belt restraint device that activates a belt tensioner using a predefined first restraint force, and subsequently transmits a second signal to a second restraint device comprising a front airbag system that triggers a front airbag; and

    a malfunction monitoring unit for determining correct functioning of at least one of the restraint devices, wherein in the event a malfunction of the front airbag system is recognized by the malfunction monitoring unit after recognizing the collision, the control unit, following transmission of the first and second signals, transmits a third signal to the first restraint device that activates a replacement actuator.
