Abstract

La présente invention concerne un siège de véhicule qui permet le réglage individuel, ou une action similaire, sur une pluralité de mécanismes à régler à l'aide d'un élément d'actionnement, l'amélioration de la facilité d'utilisation, et l'utilisation efficace d'un espace. Dans ce siège de véhicule (10), un levier d'actionnement (118) et un élément embrayage extérieur (86) sont normalement accouplés grâce à un élément embrayage mobile (72) et un élément similaire. Un mécanisme d'inclinaison et un mécanisme de coulissement sont accouplés à l'élément embrayage extérieur (86) et les verrouillages des mécanismes respectifs peuvent être libérés individuellement par les actionnements vers le haut ou vers le bas du levier d'actionnement (118). Simultanément, lorsqu'un élément de commutation (136) est déplacé dans une position d'actionnement, le levier d'actionnement (118) et un élément embrayage intérieur (54) sont accouplés par l'intermédiaire de l'élément embrayage mobile (72) et de l'élément similaire. L'élément embrayage intérieur (54) est accouplé à un mécanisme d'élévation, et le mécanisme d'élévation est réglé par les actionnements vers le haut et vers le bas du levier d'actionnement (118). Comme indiqué ci-dessus, la direction d'actionnement du levier d'actionnement (118) est définie uniquement vers le haut et vers le bas.
