Abstract

La chaise de l'invention possède un dossier (3), et une armature arrière (4) disposée derrière celui-ci. Une partie extrémité supérieure du dossier (3) déformable en flexion par le dossier (3) et la pression corporelle d'une personne assise, est installée sur l'armature arrière (4) à l'aide d'un premier dispositif de soutien (12), et deux parties extrémité gauche et droite d'une portion du dossier (3) à hauteur des hanches d'un utilisateur ou un peu au-dessus de celles-ci, sont installées sur l'armature arrière (4) à l'aide d'un second dispositif de soutien (13). Le premier dispositif de soutien (12) est d'une rigidité permettant sa déformation par torsion sous l'effet de la pression corporelle, et la rigidité du second dispositif de soutien (13) est supérieure à celle du premier dispositif de soutien (12). La partie hanches de l'utilisateur est soutenue de manière stable, et la partie extrémité supérieure du dossier (3), est déformable selon les mouvements du corps en mode à bascule. Le dossier (3) est constitué d'une ossature (9) configurant sa partie périphérique externe, et d'une partie soutien corporelle (10) recevant la pression corporelle de la personne assise. La partie soutien corporelle (10) se divise en une zone centrale constituée par un groupe de renforts centraux (41) horizontalement allongés, et en zones latérales constituées par des groupes de renforts latéraux (40) horizontalement allongés de manière similaire. Les renforts centraux (41) et les renforts latéraux (40) sont disposés verticalement de manière décalée, et les renforts (40, 41) latéralement adjacents sont liés d'un seul tenant par l'intermédiaire d'une pièce de raccordement (42) en position inclinée.
