LEG PROSTHESIS AND KNEE JOINT FOR A LEG PROSTHESIS

摘要

A leg prosthesis provided with a knee joint, which is on the one hand attached to an upper leg part and which is on the other hand attached to a lower leg part. The lower leg part can pivot with respect to said upper leg part, from an extended position to a flexed position. The knee joint is constructed in such a manner that the lower leg part and the upper leg part are initially moved away from each other when flexing from a substantially extended position. The knee joint may comprise four parallel pivot axes, whereby two lower leg pivot axes occupy a fixed position with respect to the first lower leg part and two upper leg pivot axes occupy a fixed position with respect to the upper leg part. Connecting elements pivotally connect each lower leg pivot axis to an upper leg pivot axis.
