Abstract

L'invention concerne un siège pourvu d'un accoudoir. Dans un mode de réalisation, ce siège comprend : une base de support (5) soutenue par un pied ; une partie siège (6) montée pivotante sur la base de support (5) au moyen d'un axe (9) s'entendant latéralement, la partie arrière de la partie siège pouvant ainsi pivoter verticalement ; un moyen d'entraînement (10) disposé au niveau de la base de support (5) et destiné à entraîner vers le haut la partie siège (6) à l'arrière de l'axe (9) ; et un accoudoir (14) disposé sur la base de support (5). Lorsque la partie arrière de la partie siège (6) pivote verticalement, la hauteur de l'accoudoir (14) ne change pas, ce qui évite que les bras ou d'autres parties du corps de l'utilisateur se retrouvent coincées entre le bureau et l'accoudoir (14).
