Abstract

L'invention concerne un appareil de support de siège. L'appareil de support de siège est utilisé en tant que mécanisme de support de siège, le siège (D) étant déplacé de manière pivotante d'une position d'assise inclinée vers l'avant plus élevée à une position d'assise inclinée vers l'arrière inférieure sur un axe de pivotement transversal avec un point d'appui représentant l'articulation du genou (4.b). L'appareil comprend deux paires de leviers articulés à pivotement transversal, qui forment un parallélogramme entre la base de palier (2) et une structure de support de siège (6). La structure de support de siège (6) forme un parallélépipède avec deux côtés opposés inégaux, la partie (4) étant plus longue que la partie (5), de telle sorte que la rotation simule la rotation de la cuisse avec le point d'appui dans l'articulation de genou (4.b) et supporte ainsi uniformément la longueur de la cuisse par l'intermédiaire de son mouvement entier. Un troisième levier pivotant transversal (7) est en prise au moyen d'un engrenage de surface hélicoïdale (7.2) avec le levier de pivot arrière (4) dans un point (4.4) pour forcer un mouvement synchronisé inverse du dossier lorsqu'il s'incline vers le haut, ouvrant ainsi l'angle entre la cuisse et le corps supérieur.
