Abstract

La présente invention concerne un dispositif d'actionnement de siège de véhicule, qui comprend : un boîtier porté par un arbre ; une came de frein située dans le boîtier de façon à tourner d'un seul tenant avec l'arbre ; une paire de ressorts de frein placés de manière à être symétriques l'un par rapport à l'autre sur le côté extérieur de la came de frein, introduits de façon à entrer en contact étroit avec la surface périphérique intérieure du boîtier, et comprimés de manière sélective selon le sens de rotation de ladite came de frein et espacés l'un de l'autre, ce qui permet d'empêcher la rotation de cette came de frein dans un sens et dans l'autre sens au moyen de la force de frottement générée entre la surface périphérique intérieure du boîtier et le ressort de frein ; une plaque de commande dotée de bras saillants qui sont voisins dans la direction de l'arbre sur la paire de ressorts de frein, et appuyant de façon sélective sur la paire de ressorts de frein et la rétractant lors de la rotation, ce qui permet de faire tourner les ressorts de frein dans un sens ou dans l'autre sens, et de faire tourner la came de frein dans le même sens ; ainsi qu'un moyen d'embrayage bidirectionnel qui se trouve sur un côté de la plaque de commande dans la direction de l'arbre de manière à entrer en prise avec ladite plaque de commande et à tourner d'un seul tenant avec elle lors de l'entrée de la rotation, et à libérer l'entrée en prise avec la plaque de commande et à renvoyer cette plaque de commande à sa position d'origine lorsque l'entrée de rotation est libérée. Par conséquent, la présente invention se rapporte au dispositif d'actionnement de siège de véhicule, qui réduit de façon significative le nombre de pièces, qui facilite la gestion de la précision et de la qualité, et qui simplifie la fabrication, par rapport à l'état de la technique.
