1. A motor vehicle comprising:

  • an occupant restraint device, including a control device that produces a triggering signal when a predefined hazard signal is generated as a function of signals from a safety sensor system, the occupant restraint device configured to act on a vehicle occupant by at least one impact cushion;

    wherein,the control device is configured to generate the hazard signal at least as a function of vehicle acceleration signals and a belt state signal representing activation or deactivation of a seat belt;

    the control device deactivates the occupant restraint device for a predetermined period of time or activates the occupant restraint device at reduced power if the seat belt is identified as having been deactivated;

    first vehicle acceleration signals are assigned to a critical forward displacement of the occupant if the seat belt is deactivated; and

    a forward displacement of the occupant is defined as critical when a forward displacement travel, which is calculated from the vehicle acceleration signals and an effective duration of the forward displacement travel, is greater than a threshold of the forward displacement travel.
