Artificial knee-joint
First Claim
1. An artificial knee joint for an artificial leg, comprising an upper joint part including an anterior pivoting joint and a posterior pivoting joint spaced from each other;
- a lower joint part also including an anterior pivoting joint and a posterior pivoting joint spaced from one another;
a pivotable anterior connecting bar interconnected between the anterior pivoting joint of said upper part and the anterior pivoting joint of said lower part; and
a pivotable posterior connecting bar interconnected between the posterior pivoting joint of said upper part and the posterior pivoting joint of said lower part, the imaginary connecting line extending between the anterior pivoting joint of said lower part and the posterior pivoting joint of said lower part being substantially horizontal when the leg is in a vertical position, and the imaginary connecting line extending between the anterior pivoting joint of said upper part and the anterior pivoting joint of said lower part being inclined at a relatively small angle relative to the imaginary connecting line extending between the posterior pivoting joint of said upper part and the posterior pivoting joint of said lower part.

Abstract
The artificial knee joint for an artificial leg includes a pair of substantially parallel pivotable bars which are connected by pivoting joints to an upper part and a lower part of the knee joint, respectively. One of the bars is anterior and the other is posterior with respect to a position of the artificial leg. The upper part has two spaced pivoting joints and the lower part has two spaced pivoting joints. The imaginary connecting line between the pivoting joint of the anterior bar and the pivoting joint of the posterior bar is substantially horizontal when the leg is in its vertical position. The imaginary connecting line between two pivoting joints of the anterior bar is inclined at a small angle to the imaginary connecting line between two pivoting joints of the posterior bar.
