Abstract
A jointless prosthetic foot having a leaf spring which has a distal footfall section, a connecting section and a proximal attachment section which extends in an anterior-posterior direction and to which an attachment adapter can be fixed. The attachment adapter is mounted such as to be movable along a convexly curved path in the anterior-posterior direction.
Claims24
A jointless prosthetic foot, comprising:
- a leaf spring which has a distal foot-strike section, a connecting section, and a proximal attachment section which extends in an anterior-posterior direction and on which an attachment adapter can be secured;
- wherein the attachment adapter is mounted so as to be adjustable along a convexly curved path in the anterior-posterior direction, the convexly curved path having a radius of curvature with a center point arranged in the distal foot-strike section.
A jointless prosthetic foot, comprising:
- a leaf spring comprising:
- a distal foot-strike section defining a first free end of the leaf spring;
- a connecting section;
- a proximal attachment section defining a second free end of the leaf spring;
- an attachment adapter connected to the leaf spring proximate the second free end, a position of the attachment adapter being adjustable in an anterior-posterior direction;
- wherein the foot-strike section and the attachment section have a different radius of curvature in a sagittal plane, and the proximal attachment section has a radius of curvature with a center point arranged in the distal foot-strike section.
