BUMPER ASSEMBLY FOR AIRCRAFT BOARDING BRIDGES

摘要

An engagement structure adapted for securement to the end of an aircraft boarding bridge includes a bumper assembly formed of a first bumper (22) and an auxiliary bumper (24). The auxiliary bumper is mechanically associated with a drive assembly adapted for displacing the auxiliary bumper relative to the first bumper to provide a dimensionally adjustable floor area of a boarding bridge proximate the interface of the bridge and an aircraft serviced by the bridge. The engagement structure may also include bifurcated arrangement wherein a sliding floor (17) element is associated with a length adjustable bumper subassembly (22, 24). The engagement structure provides a structure whereby the floor structure of the boarding bridge can be opened to provide a passageway for an opening or closing aircraft door. The engagement structure further provides a structure whereby the floor may then be restructured to provide an embarkation platform which extends between the aircraft and the main structure of the boarding bridge which is of adequate dimension to permit the passage of passengers between the aircraft and the boarding bridge.
