Abstract:
1. An apparatus for a lower limb prosthesis, wherein the prosthesis includes a first part providing a thigh function, a second part providing a lower leg function, a third part providing a knee function, and a fourth part providing a foot function engagable with a support, the apparatus being configured for incorporation at least partially in the third part to provide a hinged connection between the first part and the second part such that the first part and the second part may have a first position in which the first part and the second part extend substantially in a prolongation one of the other and forming a first angle, and a second position in which the first part and the second part form a second predetermined angle corresponding to the maximal flexion permitted by the prosthesis, the apparatus comprising: a first device, operatively connected between the third part and the second part, for providing a predetermined resistance at least during flexion of the prosthesis, the resistance being switched by the first device between two values which are: a predetermined maximal value selected by default, and a predetermined minimal value selected after the first part and the second part, being situated in a third position adjacent to the first position, are pulled toward the first position and are moved into this first position; and a second device including at least: a first functional means for detecting the bearing of the fourth part on the support at least by a first zone of this fourth part which corresponds to the front of a foot, and a second functional means for:
