Abstract

L'invention concerne un siège de véhicule de sorte que trois ou plusieurs mécanismes d'ajustement peuvent être ajustés de manière individuelle, par exemple, par un seul élément de fonctionnement, et de sorte qu'il est possible d'obtenir un meilleur fonctionnement et une utilisation efficace. Dans un siège de véhicule (10), un levier de fonctionnement (86) et une poulie (68) sont reliés normalement par un élément de contact (96). La poulie (68) est reliée à un mécanisme d'inclinaison et un mécanisme de coulissement de telle sorte que les mécanismes respectifs peuvent être déverrouillés de manière individuelle en actionnant le levier de fonctionnement (86) vers le haut ou vers le bas. Quand l'élément de contact (96) est déplacé sur une position de fonctionnement, le levier de fonctionnement (86) est relié à un levier de transmission (94) par le biais de l'élément de contact (96). Le levier de transmission (94) est relié à un mécanisme élévateur de sorte que le mécanisme élévateur peut être ajusté par l'actionnement vers le haut ou vers le bas du levier de fonctionnement (86). Ainsi, les directions d'actionnement du levier de fonctionnement (86) sont limitées aux directions allant vers le haut et vers le bas, de manière à pouvoir obtenir un meilleur fonctionnement et une utilisation efficace.
