  • adversely What is state of the art is that such chairs are not are collapsible and are therefore not stored in a space-saving manner can and that on the other hand the mechanics for adjusting the Backrest inclination is relatively complicated and therefore expensive.
  • DE 298 24 476 U1 and WO 91/03192 are non-folding chairs with a known backrest attached to at least one spar, each spar is divided between the seat and the backrest and the parting line by means of a rod-shaped spring element is bridged.
  • the spar halves point according to DE 298 24 476 U1 holes of different diameters to accommodate the Spring element on, wherein the holes in one on the end faces of the respective spar halves beginning in the first area have a larger diameter have and a narrower in a subsequent area Have diameter in which one end of each Spring element is attached to a length of at least 25 mm.
  • the spring elements at each end screwed In the Solution according to WO 92/03192 are the spring elements at each end screwed.
  • This prior art has the disadvantage that the described chairs are not collapsible and by using a Plastic spring element, as in the solution according to DE 298 24 476 U1der Case is, only a comparatively low stiffness is achieved.
  • the invention tries to overcome these disadvantages of the known state of the art Avoid technology. It is based on the task of a folding chair with a Metal frame, a seat and a backrest to develop which can be folded well on the one hand and on the other hand with a simple one technical means to adapt the backrest inclination to the Sitting position of a user ensures a high level of comfort.
  • the Folding chair should be inexpensive and easy to manufacture.
  • this is a folding chair according to the preamble of Claim 1 achieved in that the side carrier of the Metal frame each consist of two spaced apart parts, which are connected to one another by means of a connecting segment, wherein inside each connecting segment while maintaining a game one Bending spring for the purpose of giving in to the backrest under load is arranged.
  • the invention has the advantage that with relatively simple and few parts ergonomic yielding of the backrest when using the folding chair is achieved so that the seating comfort is improved.
  • the invention Chair can be made at low cost.
  • the connecting segment has the outer shape of a straight one Axis has a central part of larger diameter and two End pieces of smaller diameter, the two end pieces each in Inside the side support of the metal frame are arranged and that visible middle part of the connecting segment the outer shape of the Has metal frame.
  • the connecting segment can be constructed in one piece or it consists advantageously of two structurally identical parts, which are in the installed condition opposite end faces of the two halves of the Middle part have a toothing by means of which they can be plugged together.
  • the spiral spring is advantageously made of a high-strength steel because it can achieve high bending stiffness and thus the chair also high Stresses.
  • Fig. 1 shows a partial exploded view of the entire invention Folding chairs in a first preferred embodiment, while in the Fig. 2 to 5 each an enlarged section of the metal frame of this Folding chair according to the invention in the area of the built-in spiral spring is shown.
  • 6 shows a partial exploded view of a part of the folding chair according to the invention in a second embodiment.
  • the folding chair 1 consists in essentially of a seat 2, a backrest 3 and a metal frame 4, on which the seat 2 and the backrest 3 are arranged.
  • the seat 2 is after foldable up to the backrest 3, so that the kappstuhl 1 saves space can be kept when not in use.
  • the metal frame 4 is made again, on the one hand, from two front legs 5 oriented obliquely towards the front and a horizontal connecting part 6 connecting the front legs 5, which carries the seat 2, and on the other hand from two diagonally to the rear aligned rear legs 7, which are angled at seat height in side straps 8 pass over.
  • the carrier 8 are connected to the backrest 3 and carry this.
  • On the carriers 8 are also each in this embodiment Armrests 10 arranged.
  • the side supports 8 of the metal frame 4 each consist of two parts spaced from each other, which according to the invention with a Connection segment 12 are interconnected. Inside everyone Connecting segment 12 is while maintaining a certain game, which allows deflection, a spiral spring 11 arranged, the The backrest 3 gives way under load.
  • the spiral spring 11 is in Fig. 1 only visible in the exploded view in the right part of FIG. 1.
  • the Fig. 2 to 5 show everything in the installed state. To better understand the Invention, it is advantageous to consider Figures 1-5 simultaneously.
  • the spiral spring 11 in the exemplary embodiment described here consists of a high-strength steel wire with 9 mm diameter. It is in the installed state (see FIGS. 2 to 5) in the consisting of two identical parts 12 ', 12 " Connection segment 12 mounted, which with its two end pieces 13 ', 13 " is arranged inside the side supports 8 of the metal frame 4. Due to the identical construction of the parts 12 ', 12 "is advantageously an inexpensive one Manufacturing possible.
  • the connecting segment 12 connects the two sections of the side Carrier 8 of the metal frame 4 with each other. It has the outer shape of a straight axis with one transverse to the longitudinal direction in two halves 9 ', 9 " divided middle part 9 of larger diameter and with two end pieces 13 ', 13 " smaller diameter.
  • the visible in the installed middle part 9 of the Connecting segment 12 has the outer shape of the metal frame 4, so that there is no disadvantageous interruption in the design of the shape.
  • the spiral spring 11 and the connecting segment 12 are each on the two End pieces 13 ', 13 "of the connecting segment 12 with the help of two Securing pins 18 secured to the carriers 8 of the metal frame 4.
  • the Locking pins 18 are only attached to the underside of the carrier 8, what 3, 4 and 5 can be clearly seen. Between parts 11 and 12 a certain play in the installed state, so that a deformation of the Bending spring 11 in the loaded state is made possible.
  • the middle parts 9 ', 9 " (or the parts 12', 12") have on their end faces 15 ', 15 ", d. H. on the surfaces that face each other when installed Tooth 16, by means of which the parts can be plugged together (see Fig. 2nd and 3).
  • This toothing 16 is designed so that it is in the unloaded state has a game 17, which on the underside (pressure side) of the built Connection segment 12 is largest (see Fig. 4). In the loaded state (see FIG. 5) this game 17 is no longer present in the extreme case or is much less than in the unloaded state.
  • the identical parts 12 ', 12 " the connecting segment 12 are in the loaded state to secure the Pivot point of the spiral spring 11 in position using a holding pin 14 positioned.
