Pivotable canopy roof of an air passenger stair or an air passenger bridge

A pivotable canopy roof for an air passenger stair or an air passenger bridge of the type having a portal frame, the canopy roof comprising:

• a flexible frame defining a front end of the pivotable canopy roof;
• a bellows disposed between the flexible frame and the portal frame;
• a first and a second articulated arm disposed in a spaced-apart relationship, the arms connecting the flexible frame to a portal frame of an air passenger stair or an air passenger bridge, each of the articulated arms having an upper arm articulately connected to the portal frame and a lower arm articulately connected to the upper arm, the lower arms each having an end member;
• wherein the end member of at least one of the articulated arms is laterally pivotable about a pivot joint;
• and
• an actuation device for pivoting the canopy roof, the actuation device including at least one traction element, at least one roll for the at least one traction element, the roll being disposed in the area of the portal frame, the traction element being laterally articulated on the end member of the at least one articulated arm in such a manner that the end member is pulled straight when retracting the first articulated arm.
