ABSTRACT:
In an elevator system that has an elevator hoistway, a plurality of hoistway doors arranged above each other each with at least one horizontally moveable hoistway door panel, and an elevator car with a car door that has at least one horizontally movable car door panel, fastened to the car door panel is a vertically extending barrier rail. In each of the areas lying in the vertical direction between the hoistway door panels of adjacent hoistway doors two locationally fixed stopping dogs that are vertically spaced from each other are arranged so that in each case one of the stopping dogs limits the opening movement of the barrier rail, and thereby of the car door panel, when the position of the elevator car deviates in the upward direction or in the downward direction by a certain minimum distance from the intended stopping position.
