The invention relates to a flexible floor for an intercommunication bellows between two cars which, while they are traveling in a straight line, move in a longitudinal direction, said floor presenting transverse undulations enabling it to follow the relative displacements of said cars as they are going around bends, while also enabling passengers to go between the cars by walking on the top face of the floor, said transverse undulations being reinforced by metal blades extending in a transverse direction of the floor, and said floor being provided with an elastomer reinforcement interposed between the blades of each pair of said metal blades. In the floor, said elastomer reinforcements are of substantially the same transverse dimension 2L.sub.0, and each of them is constituted by at least one elastomer block, and, for at least one pair of metal blades adjacent to a longitudinal end of the floor, the elastomer reinforcement interposed between said metal blades is made up of at least two blocks which are spaced apart from the longitudinal plane symmetry of the floor, which plane is parallel to said longitudinal direction.
The subject matter of the invention is a bellows (1) of a connection between two hinge-linked vehicles (5, 6), said bellows (1), which comprises a bellows bottom (4), a bellows roof (2) and bellows side walls (3), forming a tunnel-like tube, said bellows bottom (4) being a removable constituent part of said bellows (1), said bellows (1) having a plurality of frames (10) disposed one behind the other in the longitudinal direction of said bellows (1), said bellows bottom (4) having a plurality of ledges (20) disposed one behind the other, there being provided, to connect a respective one of a frame (10) with a ledge (20), a spring cramp (30) taking hold of the frame and the ledge, said spring cramp (30) having at least one shoulder (33) for matingly connecting frame (10) and ledge (20).
