  • the cover will fixed with locking pins on the lower part of the frame.
  • a backrest with a backrest frame which consists of two lateral tubular struts and a lower and an upper cross strut is made of flat steel.
  • the side struts exist made of an aluminum profile with an undercut longitudinal groove, inserted into the piping rods attached to the side edges of a cover become. Keder seams are attached to the cover at the top and bottom, into which the flat steel struts are inserted. Then the Frame screwed together.
  • the invention has for its object a backrest for one To create a chair that is easy to assemble and an even one Allows tension of the cover in all directions.
  • the cover Due to the strong rounding in the transition areas between the Legs and the upper web of the upper frame part on the one hand and the relatively large recesses in the corner areas of the cover are ensured that the three piping hems of the cover, which the upper web and are assigned to the side legs of the upper frame part, can be pushed one after the other over the upper frame part.
  • the cover In the rounded transition areas the cover has a fabric or design adapted to a knitted fabric.

  • the frame parts 2 and 3 consist of curved Pipes of the same inside and outside diameter.
  • the lower frame part 3 has the shape of a lying C and has at the free ends of it Legs 5, 6 bolts 7, 8, which are adapted to the inner diameter of the tubes are and in the free ends of the legs 9, 10 of the upper frame part 2 can be inserted.
  • the lower clamp 4 is at its ends with Provide pipe bushings 11 which can be plugged onto the bolts 7, 8, so that after mounting the clamp 4 between the upper Frame part 2 and the lower frame part 3 is arranged and with these forms a unit, as can be seen from FIG. 3.
  • a bracket tab 13 At web 12 of the lower one Frame part 3 is a bracket tab 13 for attachment to the seat support or the like of a chair attached.

Because of the flexibility of the cover 22 and the relatively large area Recesses 27, 28 and sufficiently wide welt seams 23 to 26 can the cover is easily pushed onto the upper frame part 2, so that then the legs 9, 10 in the welt seams 23, 25 and the web 14 are located in the welt hem 24.
  • the clamp 4 is by the lower piping hem 26 pushed and then with its tubular bushings 11 the bolts 7, 8 placed.
  • the lower frame part with the clamping bracket 4 inserted into the free ends of the legs 9, 10, which completes the assembly. It can then be in the area the bolts 7, 8 each use a locking screw, not shown become.
  • the dimensions of the cover 22 are such that it at the described assembly vertically and horizontally, ie between web 14 and Clamp 4 on the one hand and the legs 9, 10 on the other hand evenly is excited.
