Abstract: A lower leg prosthesis, for an amputee who has at least one leg having a leg stump, has a distal end and a proximal end. The distal end is connectable to an artificial foot. The proximal end is connectable to the leg stump via a stump socket. A use condition of the lower leg prosthesis includes the distal end being connected to the artificial foot and the proximal end being connected to the leg stump via the stump socket.

Abstract: The invention relates to a frame for a sporting device for coupling to a shoe, such as a ski which is slidable or rollable by means of wheels, in particular a cross-country ski, or a skate frame for an ice-skate or roller-skate, which frame comprises: an upper sub-frame with means for coupling to a shoe to be worn by a user, a lower sub-frame which is coupled via a pivot mechanism to said upper sub-frame for pivoting in a main plane and which is provided with or adapted to be provided with a runner or wheels; and a resetting spring for urging both sub-frames toward each other. The frame according to the invention has the special feature that the sub-frames are mutually pivotable and translatable in the said main plane. A specific embodiment has the feature that the sub-frames form part of a mechanism comprising at least four mutually pivotable and/or translatable rods.
