Abstract (en)
The bellow has an outer skin (22) presenting a succession of outgoing undulations (56), and an inner skin (24) presenting a succession of entering undulations (58) arranged opposite to the outgoing undulations of the outer skin. The skins define a closed sound insulation space (25) between them, where the inner skin is linked to the outgoing undulations of the outer skin. The outer and inner skins present a closed section and are linked with the few undulations (56, 58) with respect to remaining undulations (56, 58) of the skins separated from each other. An independent claim is also included for an intercommunication zone with two end walls of two successive cars of a rail vehicle, where each wall delimits a passage opening.
