A cabin for a passenger bridge for the enplaning and deplaning of passengers, which passenger bridge has the form of a tunnel and is equipped with the said cabin at its outer free end, and which can be manoeuvred relative to the ground and to the airplane such that the cabin can be docked to an airplane at a door of the airplane, which cabin comprises a roof, side walls and a floor together with an opening at its free end. The invention is characterized in that displacement of the cabin towards an airplane fuselage is limited in that a flexible strip (2, 3) is placed at at least either the roof or the floor of the cabin, that the said strip (2, 3) has an inner straight longitudinal cavity with a source (5) of light located at the first short end of the said strip (2) opposite to the inner cavity of the strip (2, 3), that a photodetector (7) is located at the second short end of the strip (2) opposite the said inner cavity, and that the strip (2, 3) will be brought into contact with the airplane fuselage when the cabin is displaced towards the airplane fuselage, whereby the strip (2, 3) is arranged to be compressed such that a light signal to the said photodetector (7) from the source (5) of light is broken in that the inner cavity (4) is compressed. |
