Abstract

L'invention concerne un élément de meuble à nivellement automatique comportant trois pieds ou plus, par exemple une table ou une chaise, qui tient sans vaciller grâce aux pieds (3b) pouvant être raccourcis ou rallongés individuellement au moyen d'un moteur même sur un sol non plat et incliné, par la signalisation d'une force minimale de chaque pied sur le sol, et qui met en plus la surface utile du meuble en une position horizontale ou oblique définie par le biais de capteurs d'inclinaison (5) et d'une commande (6).
