Abstract:
1. A knee orthosis, comprising: a thigh structure, which has a first fastening member for securing to a thigh; a lower leg structure, which is coupled pivotably to the thigh structure via a joint mechanism and has a second fastening member for securing to a lower leg; a hydraulic actuator unit between the thigh structure and the lower leg structure, the hydraulic actuator unit including fastening points, on the thigh structure and on the lower leg structure, and the center of rotation of the joint mechanism form a triangle, and the fastening points are arranged on the thigh and lower leg structures in such a way that the connecting line between the fastening points is perpendicular to a connecting line between one of the fastening points and the center of rotation in an angular position of the knee in which the lower leg is bent at an angle of between 0° and 90° relative to the thigh; wherein the hydraulic actuator unit and the fastening points of the hydraulic actuator unit are mounted so as to be movable or pivotable in a lateral plane, which extends laterally from a medial side to a lateral side of the knee orthosis, wherein the hydraulic actuator unit is arranged in the lateral plane, tilted about an angle θ relative to a longitudinal axis of the thigh structure when the thigh structure and the lower leg structure are aligned.
