ABSTRACT:
The present invention relates to an arrangement for a leg prosthesis (10) provided with a foot (12), which is connected to the leg prosthesis via an articulated axle (11), whereby first means (13, 14, 16–18, 30–33, 38) are arranged to provide a limited rotation of the foot relative the leg prosthesis from an initial position, in which position the leg prosthesis and the foot have a fixed angle relative each other, and second means (16–26) are arranged to provide a step-less adjustment of the fixed angle between the leg prosthesis and the foot in the initial position. According to the invention the first means (13, 14, 16–18, 30–33, 38) comprise a resilient element (14), which first end thereof is connected to the foot (12) via an elongated element (13) and which second end is connected to the leg prosthesis so that the leg prosthesis can be rotated relative the foot against the effect of the spring force of the resilient element.
