    摘要： The prosthetic foot (1) consists of three or four laminas, a lower lamina (1a) defining the under-heel and the foot front, a rear lamina (1 b) defining the heel and functioning as the Achilles tendon and as the soleus muscle, two upper laminas (1c and 1d) defining the front part of the foot and performing the function of the front tibial muscle, and a connector (2) in proximity to the ankle to serve as a coupling for a tube (3). The aim of this prosthetic foot is to simulate the behaviour of the human foot, in such a manner as to ensure good rear flexure and effective plantar flexure. The use of three or four laminas enables continuous energy absorption/return by the foot such as to allow assisted walking by the prosthetic foot at every moment. The prosthetic foot always operates via at least two laminas, of which one absorbs and the other returns energy. The device is arranged to be housed within an aesthetic covering.

    摘要： The present foot prosthesis includes various structural features that provide the foot with advantageous rollover properties. In certain embodiments, the foot guides rollover toward the medial side. For example, an asymmetrical upper element and a correspondingly shaped resilient ankle member support more of the wearer's weight on the lateral side as the foot rolls over. In another embodiment, stiffeners added to the resilient ankle member increase the stiffness on the lateral side relative to the medial side. In certain other embodiments, the foot provides progressively increasing support from mid stance through toe off. For example, a gap between the resilient ankle member and the lower element closes during the later portion of the wearer's gait. The closing gap increases a contact area between the resilient ankle member and the lower element, providing progressively increasing support. In another embodiment, the foot includes a gap between a lower front edge of an attachment adapter and the upper element. The gap may be filled with a resilient material.
