Flexible bellows link for pivoted section vehicle - has concertina pattern mesh inside elastic wall sheets, to limit extension

摘要

The mesh (13) is made from non extending flexible material and is laid between two contoured layers of elastic sheet (12) in a concertina pattern. This allows the sheet to be stretched without straining the mesh, with the mesh limiting the amount of extension. The sheet is contoured with the bellows folds and is secured between hoop shaped mounting frames. As the vehicle corners the different parts of the bellows can be extended to stretch the bellows folds flat. The mesh pattern is arranged with the sides of the sheet parallel to the mesh lines. The material can be used to link the concertina-connected parts of a hinged-section vehicle e.g. a bus a bus.
