A height adjustment mechanism is disclosed that includes a pedestal (1) height variability mechanism (10). The pedestal (1) height variability mechanism (10) includes a first member (17) and a biasing mechanism (5). The biasing mechanism (5) is configured to hold the first member (17) in a first position. The first member (17) has a first end (27) and a second end (29) opposite the first end (27). The biasing mechanism (5) has a first portion (7) attached to the first member (17) adjacent the first end (27) of the first member (17). The biasing mechanism (5) also has a second portion (9) attached to the first member (17) adjacent to the second end (29) of the first member (17). Preferably, a second member (18) is also provided that is moveably attached to the first member (17). The second member (18) may be configured such that movement of the second member (18) actuates height adjustment of a chair.

L'invention concerne un mécanisme de réglage en hauteur qui comprend un mécanisme de variation de hauteur (11) de colonne. Le mécanisme de variation de hauteur (10) de colonne (1) comprend un premier élément (17) et un mécanisme de sollicitation (5). Le mécanisme de sollicitation (5) est conçu pour retenir le premier élément (17) dans une première position. Le premier élément (17) présente une première extrémité (27) et une seconde extrémité (29) opposée à la première extrémité (27). Le mécanisme de sollicitation (5) présente une première partie (7) fixée au premier élément (17) de manière adjacente à la première extrémité (27) du premier élément (17). Le mécanisme de sollicitation (5) présente également une seconde partie (9) fixée au premier élément (17) de manière adjacente à la seconde extrémité (29) du premier élément (17). De préférence, un second élément (18) est également prévu, lequel est fixé mobile au premier élément (17). Le second élément (18) peut être conçu de sorte que le déplacement du second élément (18) actionne le réglage en hauteur d'une chaise.
