ABSTRACT:
A leg-propulsion assistance device for improving the individual field of a mobility of a human being. The device provides a saddle supplied with a hip fastening device. A saddle joint allows for the swiveling movement of two telescopic rods, the extension force of which is derived from a compressed spring or fluid generated under pressure, by a motor-compressor set. A link arm transmits the movement to a fixed joint in front of the user's shoe. A joint which becomes freed automatically at the end of each propulsive stride allows the link arm and foot to be raised. An automatic piloting system synchronizes the motive force with the muscular extension force of the leg and foot. The invention relates to all applications necessitating propulsion by the legs of an individual capable or not capable of exerting an intense muscular effort.
