摘要: A swing phase control for an artificial knee joint is provided with a cylinder (1) having one end closed by a head member (2) and the other end closed by a base member (3), a piston reciprocally movable within the cylinder in axial direction thereof and having a piston rod (6) passing outwards through a bore provided in the head member (2) for connection with the thigh part of a prosthesis. The head member (2) comprises a channel (12) with a check valve (13) providing a communication of the ambient with a head side first chamber (9) defined by the piston (7). The first chamber (9) communicates through a throttle passage with the base side second chamber (10) defined by the piston (7). The base member (3) comprises a vent bore (23) connecting the second chamber (10) with the ambient and a first spring (22) biasing the piston (7) towards the head member (2). Thus the swing phase control has good damping properties for movement of different speed.

摘要: A knee joint for a leg prosthesis comprising an upper joint part (2) and a lower joint part (3) which can be rotated about a joint axis (5) relative to the upper part of the joint (2), and an upper brake device (14, 15, 20, 21). The brake device comprises a first force transmission element 14, upon which the force triggering the brake effect acts, and which transfers the force at a given transmission ratio to a second force transmission element (15), which, in relation to the joint axis, transfers the displaced force in a substantially parallel direction towards a brake disc (20, 21).

摘要: A swing phase control device for an artificial knee joint is disclosed. The swing phase control device has a piston-cylinder device having a piston having a first side and a second side opposite the first side, a first chamber associated with the first side of the piston; and a second chamber associated with the second side of the piston. The swing phase control device also has a first throttle for throttling discharge of a fluid from the first chamber and configured to be closed by a first device when a predetermined pressure is reached or exceeded within the first chamber; and a second throttle for throttling discharge of a fluid from the second chamber and configured to be closed by a second device when a predetermined pressure is reached or exceeded within the second chamber.
