Abstract

La présente invention concerne un dispositif d'aide au pliage d'un dossier d'un seul coup. Elle concerne plus précisément un dispositif d'aide au pliage d'un dossier caractérisé en ce que, lorsqu'un utilisateur tire un câble de manipulation, un dossier est entraîné en rotation par une force élastique dans une direction d'une position de réglage dans laquelle le dossier forme un angle aigu prédéfini avec un coussin de siège, de sorte que l'utilisateur peut facilement plier ou incliner le dossier. En outre, le dispositif d'aide au pliage d'un dossier comprend : un moyen de raccordement de levier conçu pour raccorder et détacher des premier et second câbles, à savoir le câble de manipulation, par rapport à un distributeur de câbles sur la base d'un point de libération de verrouillage prédéterminé ; et un moyen de blocage de rotation raccordé au moyen de raccordement de levier. Par conséquent, même lorsque l'utilisateur tire le câble de manipulation d'un seul coup et en continu, le dossier ne peut présenter de secousses répétées à proximité de la position de réglage en raison de la force élastique et de l'inertie de rotation.
