Abstract

L'invention concerne un mécanisme synchronisé pour réaliser un mouvement correct de déplacement entre le siège et le dossier d'une chaise de bureau, comportant un support de base (1) pouvant être placé sur une colonne de chaise, un support de siège (3) et un support de dossier (4). L'invention vise à fournir un mécanisme synchronisé qui est conçu de manière particulièrement simple. A cet effet, le support de dossier (4) pivotant autour d'un axe transversal (13) est relié de manière articulée avec d'une part le support de base (1) et avec d'autre part le support de siège (3), de telle manière qu'un mouvement de pivotement (7) du dossier vers l'arrière induise un mouvement de relevage (H1) de la partie postérieure (25) du support de siège (3). En outre, le support de siège (3) est relié de manière articulée au support de base (1) par un élément de couplage (21) articulé sur le support de siège (3) et sur le support de base (1), de manière qu'un mouvement de relevage (H2) se produise également au niveau de la partie avant (26) du support de siège (3).
