Abstract

L'invention concerne un siège, en particulier un siège de travail comportant un dossier (2) relié à une partie d'assise par l'intermédiaire d'un élément de retenue (7), ledit dossier pouvant être déplacé par rapport à la partie d'assise de sorte à effectuer, vu d'en haut, un mouvement de rotation par rapport à la partie d'assise. Ledit siège présente un joint articulé (6) pour assurer le mouvement de rotation, qui comprend un corps creux (9) et un corps d'articulation monté rotatif sur le corps creux (9) et est doté d'une suspension à ressort pour assurer le mouvement de rotation. Une butée limitant le mouvement du corps d'articulation est formée dans le corps creux (9) et ledit corps creux (9) présente un tube de préférence cylindrique ou rectangulaire en section transversale et ledit corps creux peut tourner autour d'un axe de rotation (5) perpendiculaire à un axe longitudinal du tube (9).
