1. A device for connecting and mutually pivoting parts of an orthopaedic apparatus having an extension side and a flexion side opposite said extension side, said device comprising:

  • a kinematic multiple linkage system with at least four linkages, adjoining linkages of said at least four linkages having a common pivot axis, wherein the pivot axes extend substantially mutually parallel;

    an extension side linkage of said at least four linkages located on said extension side, directly pivotally connected only to an upper output linkage of said at least four linkages and to a lower output linkage of said at least four linkages; and

    a flexion side linkage of said at least four linkages, located on said flexion side, pivotally connected on one side to the upper output linkage of said at least four linkages and connected on another side to the lower output linkage of said at least four linkages such that said flexion side linkage performs a constrained movement relative to the lower output linkage which comprises translation as well as rotation,said flexion side linkage being connected to said lower output linkage at two points by two means for connecting, andboth said two means for connecting being pivotally connected to both said flexion side linkage and said lower output linkage.
