Abstract

L'invention concerne un dispositif de réglage en hauteur (5) pour un siège de véhicule (1), comprenant au moins une coulisse (7, 9), laquelle est amenée en rotation par rapport à une bielle (3, 11) autour d'un point d'articulation (22, 24, 26, 28). Au point d'articulation (22, 24, 26, 28) est associé un dispositif collecteur (40), lequel est configuré comme un système de commande de coulisse. A cet effet, un évidement (36) en forme de trou oblong, lequel est traversé par un élément de guidage (30) relié de manière solidaire en rotation à la bielle (3, 11), est ménagé dans la coulisse (7, 9).
