Abstract

L'invention concerne un module de barre omnibus dans lequel la rotation d'une seconde pièce (87) dans une première direction (C1) par rapport à une première pièce (83) amène une pièce de mise en contact (91) à pénétrer dans un trou traversant de pièce de mise en contact (86) et une partie saillante de mise en contact (93) à saisir la section de bord du trou traversant de pièce de mise en contact (86). Il en résulte qu'une rotation de la seconde pièce (87) dans une seconde direction (C2), qui est la direction opposée à la première direction (C1), par rapport à la première pièce (83) est limitée.
