wherein, when the means for varying the distance shortens the distance, the force that opposed the movement of the ends of the leg segment toward each other increased, and wherein the means for varying the distance (d) is located on the pelvis segment, and
wherein the means for varying the distance (d) comprise a device for pretensioning the spring element.
