Abstract: A bellows for an airplane boarding corridor for passengers, and a corridor including such bellows. A bellows actuator device of the invention has chambers that can be inflated and deflated on command to enable the bellows to be extended and to allow the bellows to be retracted, and it also returns the bellows to the retracted condition. Advantageously, the inflatable chambers of the actuator device of the invention form at least two rows of tubes disposed symmetrically or substantially symmetrically about a longitudinal plane of symmetry of the bellows, each row being individually inflatable. The present invention is mainly applicable to making equipment, in particular weatherproofing bellows, for airport boarding corridors for passengers.

Abstract: A gangway bellows for rolling stock, where the bellows has corrugated regions forming a deformable volume, and comprises a plurality of assembled-together modules, each module being made of a rubber-base material and including at least two corrugated regions that are assembled together by vulcanization.
