Patent ID: 8721736

Claim:
A damping device for a prosthesis, comprising a first member for connection to a first component, a second member for connection to another component, and a means for coupling together the first member and the second member and for relative displacement of the first member and the second member, and a damping element which is arranged to counteract a relative displacement between the first member and the second member when loading the damping device, wherein the coupling means comprises first and second linkage arms, both being pivotally arranged in relation to the first member and the second member, wherein the first and second linkage arms are arranged at different positions with respect to a main damping direction of the damping device for substantially maintaining the relative orientations of the first member and the second member when loading the damping device, when the first member and the second member are displaced in relation to each other during pivoting of the first and second linkage arms and exertion of influence on the damping element: wherein the first and second linkage arms each exhibit a first geometrical axis of rotation for relative pivoting of the first and second linkage arms and the first member, and a second geometrical axis of rotation for relative pivoting of the first and second linkage arms and the second member; wherein said first geometrical axes of rotation, about which the first and second linkage arms and the first member are pivotable in relation to each other, are arranged at different positions along a first geometrical line that is substantially parallel to the main damping direction and move in a linear direction; wherein said second geometrical axes of rotation, about which the first and second linkage arms and the second member are pivotable in relation to each other, are arranged at different positions along a second geometrical line that is substantially parallel to the main damping direction and move in a linear direction.
