Abstract
A bellows has integral connecting members joining the side wall and floor or roof fabricated from a sheet of flexible material with displaced longitudinal folds having adjacent seams to form a tongue and a pocket for receiving the tongue when the sections are pivoted with respect to one another.

Bellows as a passage protection means between two vehicles connected to one another in an articulated manner, wherein a plurality of folds follow each other in the longitudinal direction of the bellows forming a tunnel that is closed all around, and two outer fold edges of one fold are grasped in a frame, and fold walls extending obliquely inwardly from the outer fold edges converge in an inner edge, which is approximately the apex line of an arc, characterized in that in each transition area between one of the bellows side walls and the bellows floor, the area of the inner edge (4) is characterized by a fixing seam (8, 9);
- that this seam consists of two seam sections (8 and 9) located at spaced locations from one another in the longitudinal direction of the seam;
- and that the transition between the floor of the bellows and the respective side wall of the bellows is formed by pivoting the bellows material from an initial single plane into two planes that are at right angles to one another, wherein the area between the seam sections forms the range of pivoting, so that the beginning (A) of one seam section (8) defines the floor, the beginning (B) of the other seam section (9), which faces that seam section, defines the side wall, and the side wall part located closest to the floor of the bellows protrudes, in the manner of a tongue, into a pocket formed by the floor part located closest to the side wall of the bellows.
A bellows for protecting a passageway between two vehicles connected in an articulated manner, said bellows being flexible for assuming straight and curved positions, and comprising
- two side walls,
- at least one transverse wall spanning said side walls, and
- connecting means integral with one of said side walls and said transverse wall for joining said side wall and transverse wall, said connecting means comprising an elongated sheet of flexible material having opposite edges, a first section integral with said side wall, a second section longitudinally displaced from said first section and integral with the said transverse wall of said bellows, and a third section intermediate said first and second sections,
- each of said first and second sections having a longitudinal fold along a length thereof for forming two panels within each of said first and second sections,
- first fastening means connecting the panels within said first section adjacent the fold of said first section for forming a tongue on said first section,
- second fastening means connecting the panels within said second section adjacent the fold of said second section for forming a pocket within said second section,
- said first section being pivotal relative to said second section at said third section whereby said tongue is received in said pocket.
