Abstract
Un mécanisme de levage a une base sur laquelle un pivot d'une structure en parallélogramme. Un ressort s'étend d'une première liaison du parallélogramme à un point de terminaison réglable sur une seconde liaison du parallélogramme pour former un triangle de levage. Le point de terminaison de ressort est déplacé à partir d'un pivot principal du parallélogramme pour créer un "bras de levier" réglable pour faire varier la force de levage. Un mécanisme de réglage de puissance de levage règle la position du point de terminaison de ressort. Une extension est fixe par rapport à l'une des liaisons du parallélogramme et maintient son angle par rapport à l'horizontale lorsque des angles du parallélogramme varient lors de l'élévation ou de l'abaissement du mécanisme de levage entre un mode d'assise et un mode debout. L'extension sert de base pour une section de siège arrière. Une section de siège avant est fixée de manière pivotante à la section de siège arrière lui permettant de pivoter vers le bas lors de l'élévation du mécanisme de levage.
