Abstract
An artificial knee joint includes a shank formed with a pair of upwardly extending first lugs and a pair of radially extending second lugs, and a thigh support formed with a pair of downwardly extending third lugs which are connected pivotally to the first lugs. A connector has a first portion which extends between and which is mounted pivotally to the third lugs, a second portion which extends from the first portion and which extends between the first lugs, and a connecting portion formed at a junction of the first and second portions. A biasing unit on the shank biases the second portion of the connector upwardly. The connecting portion of the connector extends between and is connected pivotally to a spaced pair of pivot blocks on an upper end of an actuating member. The actuating member further has a lower end which extends between and which is connected pivotally to the second lugs. Each of a pair of damping units is provided on a respective one of the first lugs so as to bias the pivot blocks, respectively.
