  • Patent number: 9107735
    Abstract: A hinge for knee joint orthoses, prostheses and/or braces includes first and second hinge brackets overlappingly connected to each other at their ends so that with increasing angle therebetween, a combined rolling and sliding movement is effected in a plane defined by the two hinge brackets. Curves and guide elements at the overlapping ends of the hinge brackets interact such that with increasing angle therebetween, a combined rolling and sliding movement of the second hinge bracket is effected in the plane defined by the two hinge brackets in a direction which leads substantially radial to the axis of the first hinge bracket into the quadrant enclosed between the two hinge brackets, wherein the center of rotation of the two hinge brackets remains substantially stationary for an angle between the hinge brackets of between 0 and 25°.

  • Publication number: 20120296248
    Abstract: A support body (1) for knee orthoses and/or knee joint braces in the form of a splint (2) which extends along and partially encloses the lower leg of a wearer and is connected at the upper end to an orthosis hinge or a hinge of a knee joint brace and which is provided at a lower end with a foot part (3) receiving at least the heel of a wearer. At the upper end of the splint (2), two connection points (4) for the knee orthosis and/or knee joint braces are arranged laterally to the wearer's leg, which connection points transition into a section which runs downward at the wearer's shin bone along the leg and which, on its part, transitions again above the wearer's ankle region into two connecting parts (6) which run laterally to the leg to the foot part (3).

  • Patent number: 7597716
    Abstract: The invention relates to a knee joint prosthesis comprising two arched guiding elements (3, 4) with a variable curvature in a first body (1) associated with the thigh, bolts (6, 7), or the like, of a second body (2) associated with the lower leg engaging in said guiding elements. The points XP(?), YP(?) of one guiding element (3) and the points XQ(?) and YQ(?) of the other guiding element (4) correspond approximately to the following equations: XP(?)=A1×?5+B1×?4+C1×?3+D1×?2+E1×??F1; YP(?)=A2×?5+B2×?4+C2×?3+D2×?2+E2×??F2; XQ(?)=A3×?5+B3×?4+C3×?3+D3×?2+E3×??F3; YQ(?)=A4×?5+B4×?4+C4×?3+D4×?2+E4×??F3, the deflection angle f of the knee joint being indicated in radians. The inventive knee joint prosthesis enables a significant adaptation to the natural movement.

  • Patent number: 6488711
    Abstract: The invention relates to a (knee) joint for positioning two pivoting parts in such a way that they can pivot within a limited range. According to the invention, a combined turning and sliding movement is produced by means of curved guides (6, 6′, 7, 7′). A cam body (8) connected to one pivoting part, e.g. the lower leg, has two cams (10, 11; 13, 14), preferably on each side. Said cams interact with the curved guides (6, 6′, 7, 7′). The curved guides (6, 6′, 7, 7′) are located in half-shells (3, 4) which are connected to the second pivoting part, e.g. the upper leg. Parts of the inventive knee joint which are subject to wear are relatively easy to replace and movement sequences can also be modified when replacements are made.
