An orthesis joint comprising a first plate, a second plate, a thigh attachment part and a leg attachment part, a first bushing coupling said thigh attachment part to said first and second plates, a second bushing coupling said leg attachment part to said first and second plates, said leg and thigh attachment parts having slotted recesses in which a connecting member is positioned, said connecting member coupled to said leg attachment part and said thigh attachment part, said second plate having a portion defining a hole, a bush coupled to said connecting member and which also extends through said hole, said attachment parts and connecting member coupled together for relative rotatable movement with respect to each other and said plates and a pressure cushion member coupled to said bush on the side of said hole opposite said hole side closest to the connecting member so that the pressure cushion will not interfere with the movement of the attachment parts and move with the connecting member as the thigh part and leg part are rotatably moved relative to one another.
An orthesis joint comprising a first support plate,
- a thigh attachment part which is hingedly connected to first support plate through a first bearing bush,
- a lower leg attachment part which is hingedly connected to said first support plate through a second bearing bush,
- a connecting member which is hingedly connected to both said attachment parts through a third and fourth, respectively, bearing bush,
- a pressure cushion for preventing the orthesis joint from chafing at the knee when stretching or flexing the joint
- a connector supporting and coupled to said pressure cushion and said connecting member to rigidly connect said pressure cushion to said connecting member for movement therewith.
