Definitions

  • the invention relates to a movable backrest for a chair or armchair in the living, office and vehicle area, wherein the backrest is attached via at least one flexurally elastic element to a seat frame and limited in its scrub processschwenkamba.
  • a chair of the aforementioned type is known (EP 1 306 033 B1), wherein the flexurally elastic support elements are designed as sheathed glass fiber rods and the movement limiters are formed in the region of the connection of the backrest to the seat frame as an adjustable pivoting lever.
  • a movable backrest of the type mentioned in that the flexurally elastic element is designed as a prestressed coil spring and that either a reverse Schwenkiolosbesky the backrest is arranged in the form of a rod, wire, belt or rope inside the coil spring or outside.
  • This process is effective only in the first area of the recline process, but this is the area that is anatomically of particular importance and stretches the spine and thus relieves the intervertebral discs.
  • upward movements of the back can be achieved, which are in the range of 1 to 2 cm, which is perfectly sufficient for the desired effect.
  • a movement limiter is provided. This is housed in an embodiment of the invention in the interior of the coil spring. This movement limiter sets a distance which must not be exceeded, namely the distance is determined by the lower attachment of the movement limiter to the seat frame and the upper attachment of the movement limiter in the region of the upper turns of the coil spring. It may be any tensile forces receiving element, so a rod, a wire, a belt or a rope.
  • the movement limiter is arranged outside the spiral spring.
  • a cylindrical coil spring is used. Conceivable, however, are embodiments in which the coil spring has a different cross-sectional area from the circle and the wire of the coil spring itself has a square or rectangular cross-section. In a cylindrical coil spring, it does not depend on the direction of the acting forces, which are transmitted by a person leaning to the rear on the remindiehne. For a coil spring with a circle Deviating cross-section can be achieved a direction-dependent stress on the coil spring, which then leads to a correspondingly modified lifting movement of the backrest.
  • the movement limit is adjustable by the control limiter are provided in the lower part of the connection of the movement.
  • Fig. 1 shows a front view of a backrest according to the invention in U-shape.
  • FIG. 2 shows the side view belonging to FIG.
  • Figs. 3 and 4 show corresponding side views in modified embodiments of the backrest according to the invention.
  • Fig. 5 shows the backrest of the embodiment of FIG. 4 in the bent-back state.
  • FIG. 6 shows, on an enlarged scale, the spiral spring in the bent-back position according to FIG. 5.
  • Fig. 7 shows a side view of an embodiment according to the invention with externally arranged limiter.
  • FIG. 8 shows a perspective view belonging to FIG.
  • 10 denotes a backrest.
  • a backrest not covered for purposes of clarity of presentation is shown.
  • the backrest is plate-shaped, wherein - although not shown - the backrest 10 could consist of two parts.
  • the seat frame is designated 11.
  • coil springs 1 are provided as connecting means.
  • the lower end of the coil spring is, as shown in FIG. 6 reveals, attached to the seat frame 11, such as in the way that a bore is provided in the frame into which the coil spring fits exactly.
  • On the coil spring connecting elements 4 are attached, which in turn connected to the seat back 10 in the usual manner, in particular screwed, are. It can be seen, in particular with reference to Figure 6, that by suitable dimensioning of the spring, the backrest 10 with respect to the seat frame 11 performs a pivoting or tilting movement. It can also be seen from FIG.
  • the axis of the unloaded spring 1 need not be vertically aligned, it can easily stand at an angle to the vertical, as shown in Figure 3 reveals.
  • FIG. 1 still shows screws 2, which can additionally secure the position of the spring.
