Abstract

L'invention concerne un dispositif de commande de dispositif de siège monté sur véhicule, comprenant un mécanisme de mouvement passif pour changer la posture d'un passager de telle sorte qu'un degré de mouvement d'un mouvement passif d'un passager, pendant la marche de véhicule, change. Un dispositif de commande de siège monté sur véhicule comprend : un moyen de commande (300) pour commander l'entraînement de mécanismes de mouvement passif (21, 22, 11, 12, 13) de telle sorte que le degré de mouvement passif change ; et un moyen de détection d'état de passager (200, 300) pour détecter la posture du passager, lorsque la commande des mécanismes de mouvement passif (21, 22, 11, 12, 13) est réalisée par le moyen de commande (300), ou l'état du corps du passager qui est assis sur le dispositif de siège de véhicule. Lors de l'entraînement des mécanismes de mouvement passif (21, 22, 11, 12, 13), le moyen de commande (300) ajuste le degré d'entraînement des mécanismes de mouvement passif (21, 22, 11, 12, 13) sur la base de la posture ou de l'état de corps du passager qui est détecté par le moyen de détection d'état de passager (200, 300).
