Abstract

Selon l'invention, un châssis siège réglable pour un projecteur comprend une plaque siège de positionnement à raccord fixe (1). La plaque siège de positionnement à raccord fixe est raccordée à une plaque de base réglable (3) par un joint à rotule (2). La plaque de base réglable (3) comprend une plaque siège supérieure (4) et une plaque rotative (8) et la plaque siège supérieure comporte une pièce de raccord dans le joint à rotule (2). La plaque rotative est raccordée de façon à pouvoir tourner par rapport au joint à rotule et à un arbre rotatif d'une ligne centrale perpendiculaire de la plaque siège supérieure, et est raccordée de façon fixe à un projecteur (7). Une pièce de serrage limite (5) capable de tourner relativement est placée entre la plaque siège supérieure et la plaque de positionnement à raccord fixe. La plaque à raccord fixe comporte un premier groupe d'appareils de réglage synchronisé de rétraction et de libération d'extrémité de traction (901) utilisé pour maîtriser l'oscillation et la rotation de la plaque de base réglable par rapport à un axe des X, un deuxième groupe d'appareils de réglage synchronisé de rétraction et de libération d'extrémité de traction (902) utilisé pour maîtriser l'oscillation et la rotation de la plaque de base réglable par rapport à un axe des Y, et un troisième groupe d'appareils de réglage synchronisé de rétraction et de libération d'extrémité de traction (903) utilisé pour maîtriser la rotation de la plaque de base réglable par rapport à un axe des Z. Les appareils de réglage synchronisé de rétraction et de libération d'extrémité de traction entraînent la rotation de tiges filetées grâce à des boutons rotatifs de façon à réaliser l'effet de rétraction et de libération de cordons de traction (17).
