主权项

1. A prosthetic foot, comprising:
a base spring having a forefoot region and a heel region; a heel spring arranged on the base spring; a damping element arranged between the base spring and the heel spring; a connection apparatus arranged above the base spring and configured to connect the prosthetic foot to a prosthesis; a torsion element; a frontal support having an upper end connected to the connection apparatus and a lower end secured to the torsion element; wherein the torsion element is configured to twist about the prosthetic-foot longitudinal axis, and is configured as a leaf spring apparatus that is secured at only one end to the base spring, either in the heel region or in the forefoot region, and the lower end of the frontal support having a free end, which terminates at a support area positioned approximately in a center of a length of the base spring; wherein during normal use of the prosthetic foot, a free end of the torsion element contacts the base spring at least when the forefoot region is set down in contact with a support surface and during roll over to provide force transmission from the base spring to the frontal support.
