Jalousi wall assembly for a passenger bridge

A jalousi wall assembly for a passenger bridge, which jalousi wall assembly comprises

• a first jalousi wall, in turn having a first end and a second end, which first end is arranged to be wound up on, and off from, a first roll with a first vertical rotation axis (A2), and which second end is arranged to be fastened to the passenger bridge;
• and
• a second jalousi wall, in turn having a third end and a fourth end, which third end is arranged to be wound up on, and off from, a second roll with a second vertical rotation axis (A3), and which fourth end is arranged to be fastened to the passenger bridge,
• wherein the first roll is arranged to be fastened to the frame of a movable opening of the passenger bridge and to follow horizontal movements of the said frame by the first jalousi wall being wound up on, or off from, the first roll, whereby a horizontal length of the first jalousi wall, between the first end and the second end, is adjusted in response to a horizontal movement of said frame, and
• wherein the second roll is also arranged to be fastened to the said frame and to follow horizontal movements of the frame by the second jalousi wall being wound up on, or off from, the second roll, whereby a horizontal length of the second jalousi wall, between the third end and the fourth end, is also adjusted in response to a horizontal movement of said frame,
• wherein the jalousi wall assembly further comprises a wire having a first and a second end, which first end is wound about said first vertical rotation axis (A2) such that the first jalousi wall is wound up on the first roll when the wire is pulled at its second end, in that the second end of said wire is wound about said second vertical rotation axis (A3) such that the second jalousi wall is wound up on the second roll when the wire is pulled at its first end, and in that the jalousi wall assembly further comprises a wire tension means comprising a gas spring arranged to maintain a tension in the wire while the frame moves,
• wherein the wire tension means further comprises a pulley system, allowing the wire to move freely along its length direction, and
• the gas spring is arranged to apply a pulling force to the wire via a respective spring-loaded pulley which is in rolling engagement with the wire.
