Abstract

La présente invention concerne un siège inclinable dans lequel une partie de dossier et une partie d'assise tournent en liaison l'une avec l'autre de telle sorte qu'un angle de hanche peut être ajusté simultanément lorsqu'un angle de dos est ajusté, et ainsi, un espace ne peut pas se créer entre des parties d'accoudoir disposées sur des parties avant des deux côtés de la partie de dossier et la partie d'assise et une position de jambe peut être élevée pour améliorer le confort. Le siège inclinable selon la présente invention peut comprendre : un corps principal fixé sur la surface inférieure ; un élément rotatif qui est installé sur la partie supérieure du corps principal pour pouvoir tourner autour d'un premier arbre rotatif qui est parallèle au sol ; une partie dossier qui est conçue pour supporter la partie de dos de l'utilisateur et dont la partie d'extrémité inférieure est couplée à l'élément rotatif et qui tourne conjointement avec l'élément rotatif ; une partie d'assise rotative qui est conçue pour supporter les hanches et les cuisses de l'utilisateur, et dont la partie d'extrémité arrière est reliée à l'élément rotatif par l'intermédiaire d'un second arbre rotatif pour être relativement rotative, de façon à tourner dans le sens vertical en fonction de la rotation de l'élément rotatif ; et une unité d'entraînement fournissant de l'énergie pour faire tourner l'élément rotatif.
