Problems solved by technology

[0005] Newer aircraft have a skin with a very variable profile; especially in the transition zone to the nose the fuselage of the aircraft sometimes has a large angle of curvature, so that it is not possible to ensure that the arrangement in the folded position is not guaranteed by means of ordinary aircraft passenger gangways or aircraft boarding bridges. The frame on the shed front fits precisely to the contours of the aircraft skin

Embodiment Construction

[0032] according to figure 1 and figure 2 The aircraft passenger gangway or aircraft boarding bridge comprises a portal frame 2 and a flexible frame 3 which receives at the end sides a damper 4 made of elastically flexible material, for example foam rubber. A fold bellows 5 is installed between the portal frame and the flexible frame 3 . The folded bellows 5 is designed to be U-shaped on its profile with the flexible frame 3 and the door frame 2, and is straddled above the connection floor represented by 10 as a whole. In the floor area of ​​the two side walls 5a of the bellows 5, the bellows has a plurality of bellows eyelets 6 arranged one behind the other and accommodated by a guide rail 7, wherein the guide rail 7 is fastened on the flexible frame 3 at one end and at the other end. One end side is fixed on the aircraft passenger gangway or the aircraft boarding bridge itself or on the portal frame 2 . by pressing figure 2 view of Figure 1 On the one hand a manipula...

Abstract

The invention is directed to a seal for aircraft boarding stairs or for an aircraft boarding bridge, said seal comprising a bellows ( 5 ) that spans a gangway bottom plate ( 10 ), said bellows comprising a flexible frame ( 3 ) at its one open end and having at its other end a gantry frame ( 2 ) intended to be fastened to the aircraft boarding stairs or to the aircraft boarding bridge, the flexible frame ( 3 ) resting against the outer skin of the aircraft when the bellows is deployed and an actuation device for actuating the bellows being provided for extending and retracting the bellows, said actuation device comprising a rotatable shaft equipped with a drive, said rotatable shaft ( 40 ) permitting to wind and unwind a traction means connected to the flexible frame, the actuation device ( 20 ) comprising two articulated arms ( 30 ) arranged in a spaced-apart relationship, each articulated arm ( 30 ) comprising an upper arm member ( 31 ) and a lower arm member ( 35 ) coupled to said upper arm member by a hinge, said upper arm member ( 31 ) of the articulated arm ( 30 ) being hinged to the gantry frame ( 2 ) in the roof region of the bellows ( 5 ) and the lower arm member ( 35 ) being hinged to the flexible frame ( 3 ), extension means ( 51, 55 ) being provided for extending the bellows ( 5 ).

Description

technical field [0001] The invention relates to a sealing device (Abdichtung) for an aircraft passenger gangway or an aircraft boarding bridge (Fluggastbrücke), comprising a bellows mounted spanning above the connection floor, wherein said bellows has a flexible frame at one of its open ends, And at one end there is a door-shaped frame for fixing on the gangway or boarding bridge, wherein the flexible frame rests on the aircraft skin when the bellows is extended, and an operating device for the bellows is arranged in it, The handling device here comprises a rotatable shaft provided with a drive, wherein at least one traction device connected to the flexible frame can be wound and unwound via the rotatable shaft. Background technique [0002] Aircraft passenger ramps or aerobridges are well known; they are used as entrances to aircraft and have a deployable bellows that bridge the aircraft passenger ramp or bridge to the aircraft The middle space, which protects the boarding...
