Abstract
An artificial joint for lower extremities, comprising an upper part, which has mechanisms for attaching to a user, and a lower part mounted thereon in a pivotal manner about a joint axis. The lower part can be bent in from an extended position into a flexed position. A force accumulator is associated with the joint and is loaded via a force transmission mechanism through a flexing movement of the upper part relative to the lower part and supports an extension movement of the lower part relative to the upper part at least over a part of the extension movement. The force transmission device exerts a maximum moment of extension at a bending angle between 45° to 80°.
Claims20
An artificial joint for lower extremities, comprising:
- an upper part, which has mechanisms for securing to a user;
- a lower part, which is mounted pivotably to the upper part about a joint axis and which can be flexed from an extended position to a flexed position;
- a force accumulator, which is charged via a force transmission mechanism by a flexion movement of the upper part relative to the lower part and supports an extension movement of the lower part relative to the upper part at least over a part of the extension movement;
- wherein the force transmission mechanism exerts a maximum moment of extension at a flexion angle between 45° and 80°.
An artificial joint for lower extremities, the artificial joint comprising:
- an upper part having at least one fastener configured to secure the upper part to a user;
- a lower part mounted pivotably to the upper part about a joint axis, the lower part being movable between an extended position and a flexed position;
- a force transmission mechanism supporting an extension movement of the lower part relative to the upper part at least over a part of an extension movement, the force transmission mechanism exerts a maximum moment of extension at a flexion angle between 45° and 80°;
- a force accumulator, which is charged via the force transmission mechanism by a flexion movement of the upper part relative to the lower part.
