  • the hinge 59 dips between the axes of the two hinges 52 and 53 and the lever 57 is pivoted, based on the illustration of Fig. 4 in the clockwise direction. If, starting from this position in which the back portion 31 is horizontally flat, the return drive 58 is set in motion, the back portion 46 is pivoted upwardly from the horizontal flat position. By this pivoting upward, the lever 56 moves in a clockwise direction about the axis of the hinge 52 with reference to FIG.

  • the lever 57 the distance to the axis of the hinge 62 is kept substantially constant, so that when pivoting the back portion 31 at the same time the back portion 31 is raised with the hinge joint 52, because the lever 57 is pivoted in the direction of rotation.
  • the two levers 56 and 57 can also be regarded as a kind of toggle lever pair whose effective length increases when stretched. Due to this extension, the hinge 52 is inevitably raised, ie the intermediate strut section 51 is likewise pivoted upwards, namely about the axis of the hinge 53. As can be seen in the illustration in FIG. 4, the arm 58 acts as if the arm 56 were arranged on the straight line 68 and would project with its free end beyond the axis of the hinge 52. In this consideration, it is clear that the thus-conceived lever, which would reach up to the hinge 52, forms, together with the lever 57, a toggle-lever pair whose extension angle is predetermined by the elevation angle of the back section 31.
  • FIG. 4 also shows that a circle is approximated by means of the intermediate spar section 51 through a polygon comprising the intermediate spar section 51, a part of the longitudinal spar 36 and a part of the spar 46.

  • Swinging movement near or in the lumbar area which prevents the patient is moved toward the foot of the bed when the back portion 31 is pivoted up.
  • the virtual joint 50 is dimensioned such that, when the back section 31 is perpendicular, the intermediate spar section 51 runs approximately at 45 °. That in other words, the angle which the intermediate spar portion 51 encloses with the horizontal is approximately half as large as the angle which the spine portion 31 encloses with the horizontal over the entire movement stroke.
  • the dimensioning is such that the distance between the axis of the hinge 39 to the lying surface side of the back portion 31 is smaller than the distance of the popliteal fossa of the back in an upright person who leaves the lower leg hang freely.
  • the virtual joint 50 diffracts in the lower torso area, whereas diffraction between the thigh and the hip becomes more evident only at relatively high elevation angles.
  • the patient is hardly moved in bed, while in the upper elevation area he is displaced in the direction of the free distal end of the thigh section 38 in the sense of a stand-up aid.
