Definitions

  • the invention relates to a kit for the backrest of a chair that protrudes with at least one backrest support over the seat, which consists of a circular backrest disc that can be connected to the backrest support and has connection receptacles on the horizontal diameter, and approximately L-shaped armrests, which can be connected to the connection receptacles of the backrest pane with a horizontal connecting section.
  • a kit for a backrest of this type is known from DE 34 31 017 A1. With this kit, only a specific backrest with armrests can be connected to a chair frame with a seat.
  • a chair which has approximately horizontally oriented armrests, which are part of the tubular chair frame and are connected to the back of the backrest.
  • the backrest disc has lateral bearing receptacles on the horizontal diameter, in which a semicircular washer is fixed so that the backrest disc is in a folded and a folded up position below or encloses above, the bearing receptacles on the backrest disc and the facing end edges of the semicircular ring disc are designed as rotary bearings and the inner radius of the semicircular ring disc corresponds to the radius of the backrest disc and the ring width of the semicircular ring disc is smaller than the length of the connecting section of the armrests .
  • the backrest disc is the basic element for any backrest design and can be connected to the backrest supports, e.g. be screwed.
  • the semicircular washer can assume two positions on the backrest washer, so that there are two possible positions for the semicircular washer for each of the two backrest designs described above. Therefore, there are four more variants of the backrest design, so that the kit provides a total of six variants of the backrest design.
  • the backrest pane carries a backrest cushion on the front.
  • connection receptacles of the backrest pane can be closed by means of cover elements.
  • connection of the armrests to the backrest pane can be designed such that the connection receptacles are recessed into the back of the backrest pane and have a cross section that corresponds to the end cross section of the connecting section of the armrests facing the backrest pane and that the armrests end with the ends of the connecting sections in the connection recordings of the backrest disc are inserted and fixed in it.
  • Fig. 1 only the upper end of the backrest support 10 is shown of the chair frame, since the structure of the chair frame with the seat is not important for the present invention and with the kit of the backrest plate 11, the armrests 15 and 16 and the semicircle -Ring washer 19 six different backrest designs are possible.
  • the backrest disc 11 which, depending on the chair frame design, is firmly connected to the single backrest support 10 or the two backrest supports of a double backrest support 10 ', e.g. is screwed.
  • the front of the backrest plate 11 can carry the backrest cushion 12.
  • connection receptacles 13 and 14 are approximately on the horizontal diameter recessed as depressions. These connection receptacles 13 and 14 are adapted in cross section to the end cross sections of the armrests 15 and 16 so that they can be inserted flush and connected to the backrest plate 11.
  • the armrests 15 and 16 are identical, so that the connection receptacles 13 and 14 are also identical, but rotated by 180 °.
  • the armrests 15 and 16 are approximately L-shaped and engage behind the backrest pane 11 with the connecting section 17.
  • the support sections 18 of the armrests 15 and 16 are therefore approximately horizontally forward at a predetermined distance from the backrest pane 11.
  • the distance is selected so that the semicircular annular disk 19, which is laterally mounted on the backrest disk 11 via the bearing mounts 21 and 22, has space in order to be pivoted about the pivot axis 20.
  • the pivot axis 20 is also arranged approximately on the horizontal diameter of the backrest disk 11.
  • the bearing receptacles 21 and 22 can, however, also be designed in such a way that the semicircular annular disk 19 can be connected to the backrest disk 11 only in the two positions shown in FIGS. 2 and 3, with the backrest disk 11 optionally at the bottom or at the top encloses semicircular.
  • the inner radius of the semicircular annular disk 19 is adapted to the diameter of the backrest disk 11.
  • connection receptacles 13 and 14 can be closed flush by means of cover elements.
