Abstract

La présente invention concerne un grand nombre de galets de roulement (3) qui sont mobiles le long d'un rail de suspension (1). Un arbre de suspension (6) supporté de manière pivotable par le galet de roulement (3) supporte par suspension une première entretoise (2a) ou une seconde entretoise (2b). Un mécanisme d'engrenage (8) transmet la rotation d'un arbre à inclinaison (4) à chaque arbre de suspension (6) et les entretoises (2a, 2b) pivotent en conséquence. Le rapport d'engrenage du mécanisme d'engrenage (8) correspondant à la première entretoise (2a) est établi de manière différente par rapport à celui du mécanisme d'engrenage (8) correspondant à la seconde entretoise. Par conséquent, un volet est en mesure d'ajuster les angles d'une pluralité d'entretoises (2a, 2b) à différentes vitesses et en les emboîtant.
