Abstract

L'invention concerne un dispositif de réglage en hauteur (5) d'un siège de véhicule (1), qui comprend au moins un bras oscillant (7, 9) pouvant pivoter par rapport à une partie latérale (11) autour d'un point d'articulation (22, 26), un bras de réglage (40) muni d'une partie dentée (42) et pouvant pivoter autour d'un point d'appui (30), ainsi qu'un pignon (32) pouvant tourner autour d'un axe de rotation (34) et coopérant avec la partie dentée (42) pour permettre le réglage en hauteur. La partie dentée (42) est conçue de sorte que la distance entre l'axe de rotation (34) et le point d'appui (30) varie lorsque le pignon (32) se déplace par rapport à la partie dentée (42), ladite partie dentée (42) présentant une forme convexe ou linéaire. L'invention concerne également un siège de véhicule (1) équipé d'au moins un dispositif de réglage en hauteur (5) selon l'invention.
