The described safety mechanism is embodied for elevator systems with an elevator car, which can be displaced in an elevator shaft. The entrances to the elevator shaft and to the elevator car each have at least one sliding door, which is automatically operable by means of a drive mechanism, preferably arranged on the elevator car. At least one detector device is provided at each sliding door, which is placed in the area of a crushing edge between a sliding door and a door jamb, and/or between two adjoining sliding door panels. Depending on the detected state of the monitored areas, the detector device generates a door release signal, or provides the interruption of the drive mechanism for opening the sliding door. The signals from the detector devices at the sliding doors of the elevator shaft can be received as a function of the position of the elevator car. In this case only the signals from the detector device from the sliding door of the elevator shaft can be considered, which is to be automatically opened next, together with the sliding door of the elevator car.
