Abstract
The invention relates to an artificial foot which is essentially composed of an incompressible core, a heel wedge, an inner foot and an outer foot surrounding everything. In order to achieve a prosthetic foot for normal walking with the emphasis on comfort, the following additional characteristics are proposed in accordance with the invention: a) a low positioned joint which moves in all directions; b) the joint exhibits a virtually perpendicular bolt, the lower end of which is shaped like a condyle, and the top and sides of the condyle are covered by a bearing shell; c) at the rear facing the heel, the bolt rests on a horizontal plantar buffer, which is inserted into a space in the core open to the connecting surface and to the front, and essentially acts upon the bolt like a horizontally operating pressure spring; d) the upper end of the bolt is attached to an adapter, the bottom of which is supported directly or indirectly by the core in the front area located in front of the bolt and on the plantar buffer in the rear area behind the bolt.
