An artificial foot which includes a foot blade (1) and a hollow cylindrical body (6) which extends at an angle to the foot blade and which is connected thereto in a manner to permit relative movement therebetween. The foot also includes a two-part brace (12) which is displaceable and adjustably mounted in an upper end of the cylindrical body (6) and is attached to the foot blade (1) at a lower end of the body in a manner such as to permit relative movement between the foot blade (1) and the brace (12). Displaceability and adjustability of the brace (12), and therewith angular adjustment of the foot, are achieved by virtue of the fact that the upper part of the brace (12) acts on the shaft (11) in a ball screw whose ball nut (9) is rotatable, and when necessary lockable, attached to the inner surface of the cylindrical body (6). |
