Abstract

L'invention concerne un siège doté d'un châssis (1) portant sur le sol, sur ce châssis étant monté un mécanisme synchrone (2). Ce mécanisme synchrone (2) comporte un axe de rotation principal (D1) fixe et horizontal ainsi qu'un axe de rotation secondaire (D2) horizontal pivotant autour de l'axe de rotation principale (D1). Ce mécanisme synchrone (2) comprend également une base (20), destinée à être posée sur le châssis (1) et traversé par l'axe de rotation principale (D1). Au-dessus de la base (20) est disposé un support d'assise (21) pivotant, traversé par l'axe de rotation secondaire (D2) et destiné à la fixation de l'assise (3). Des premiers dispositifs de liaison (22) sont articulés d'une part sur l'axe de rotation principal (D1) et d'autre part sur l'axe de rotation secondaire (D2). Des seconds dispositifs de liaison (23) se trouvent à l'opposé de l'axe de rotation secondaire (D2) et relient la base (20) au support d'assise (21). Sur le mécanisme synchrone (2) est fixé un dossier (4) qui pivote autour de l'axe rotation principal (D1) fixe contre la résistance d'un ensemble ressort (24), les mouvements de l'assise (3) et du dossier (4) étant mutuellement synchronisés.
