Aircraft passenger bridge sealing bellows - has scissors guide with telescopic mechanism adapting to hull shape

摘要

The sealing bellows is for a bridge used by passengers entering and leaving an aircraft, being mounted at the forward end of the bridge and having a peripheral thickened portion adapting to hulls of different shapes. The bellows is supported in the vertical direction by a scissors-type guide in turn mounted on the bridge, and incorporating a positively adjusted telescopic mechanism. The latter alters the shape of the thickened portion at the forward end of the bellows so that it fits against each particular shape of hull. Part of this mechanism can hinge on a transverse axis of the guide, while another part engages with the top part of the thickened portion. FL.
