Abstract

La présente invention concerne un mécanisme de réglage de coussin, qui comprend une plaque latérale de coussin gauche (10a), une plaque latérale de coussin droit (10b), un tuyau avant (20), un tuyau arrière (30), une tige de raccordement supérieure avant gauche (70a), une tige de raccordement supérieure avant droite (70b), une tige de raccordement inférieure avant gauche (40a), une tige de raccordement inférieure avant droite (40b), une tige de synchronisation (50), une tige de raccordement arrière gauche (80a), une tige de raccordement arrière droite (80b) et un ensemble moteur électrique à grande vitesse (100). Lorsque la hauteur du coussin est ajustée, l'ensemble moteur électrique à grande vitesse (100) entraîne la tige de raccordement arrière gauche (80a), la tige de raccordement arrière droite (80b), la tige de raccordement inférieure avant gauche (40a), la tige de raccordement inférieure avant droite (40b), la tige de raccordement supérieure avant gauche (70a), la tige de raccordement supérieure avant droite (70b), la plaque latérale de coussin gauche (10a) et la plaque latérale de coussin droite (10b) à se déplacer pour réaliser le raccordement de toutes les tiges de raccordement d'un mécanisme à cinq tiges de raccordement, de telle sorte que pendant un processus de réglage de hauteur du coussin, un changement de l'angle du coussin est réduit, en particulier puisque l'angle reste sensiblement inchangé.
