Definitions

  • the invention relates to a backrest for a chair, armchair, seat or vehicle seat.
  • the present invention has the task that in a backrest of the type mentioned not only these lateral forces, but also other stresses can be absorbed on a backrest.
  • the fatigue strength of the backrest and above all the strength of elastic parts of the backrest should also be increased.
  • the back shells are attached to a leaf spring turn, so that when one leans against the back shells, the spring causes the back shells to move upwards. This supports or raises the spine of the seated person.
  • the corresponding effect can also be used for a lateral movement of the back shells, which essentially depends on the arrangement and design of the leaf spring windings.
  • the back shells according to the invention have, by using relatively simple parts, for example a leaf spring instead of the usual rubber spring has a relatively long service life.
  • the seat or a chair is provided with the reference number 4.
  • a backrest or a support rail 120 projects upward from the seat surface 4, which can be, for example, a single, essentially horizontally oriented part (FIG. 4) or a V-shaped structure (FIG. 5).
  • a cross rail 20 is fastened to the mounting rail (120) shown in FIG. 4; on which in turn two back shells 1 are attached at a distance from one another.
  • This is the basic structure that backrests according to the prior art, but also according to the present invention.
  • the back shells 1 in a preferred embodiment are fastened to one end of a leaf spring 21 via fastening devices 22 (FIG. 2).
  • the other end of the coiled leaf spring 21 is attached to the back shell 1 at 23.
  • the leaf spring 21 tapers at one end, namely the one at which it is connected to the back shell 1, so that a tip 24 is received in a bore or recess 25 in the cross rail 20. It can be seen that the described embodiment produces a resilient connection between the supporting part 120 and the back shells 1.
  • a common sheathing which additionally creates the effect that the person sitting on a chair with a backrest according to the invention is protected from drafts.
  • a foam that preferably encloses all functional elements is suitable for the sheathing.
  • a modified construction can also be used as the spring element between the back shell 1 and the transverse rail 120.
  • Two angle irons 30 and 31 attached to the back shell 1 are connected to rubber elements 32 on their horizontal or almost horizontal surface. These rubber elements are in turn with angle or U-iron 33 in their almost horizontal plane e.g. connected by gluing, which in turn are attached to the cross rail 120.
  • the support part 120 is made so wide that the gap between the back shells 1 is completely covered.
  • the back shells 1 are of any type, preferably one, via a spring element 50 Rubber or foam block (Fig. 7 and 8) connected to a tensioned cross belt 201 behind it.
  • the cross belt can consist of the end strips of fabric or synthetic leather that normally serve as the backrest.
  • the cross belt (FIGS. 9 and 10) is stretched around the backrest in such a way that the person sitting is supported at the waist when leaning back.
  • Vertical straps 202 serve for the adjustable height fixing of the cross belt 201.
  • a limitation or a stop of the lateral movement of the back shells 1 in their upper region is also advantageous. This can be done by rubber buffers (not shown) attached in the outer area of the back shells 1.
  • the head of a seated person can be supported by double shells 11 (FIG. 4).
  • such shells 11 should be brought together above the shells 11 by a foam or other cushion bridge.
  • the holding rod 120 should then preferably be curved forwards in the upper region, so that the head is raised somewhat when the arm is leaning against it.
  • the headrest can also have the shape of a round arch.
  • the back shells and also the head shells can be made of plastic foam with inserted reinforcing rails made of metal or plastic.
