Definitions

  • the invention relates to a movable on a backrest bar suspended backrest, the backrest shield made of horizontal Sections exists.
  • Such backrests particularly in chairs for the office and Commercial area have the purpose of optimally adapting to the changing posture of the user.
  • the backrest is a further development according to EP-B 107627 which is divided into movable horizontal sections is.
  • EP-B 308538 there the backrest is suspended so that it versus longitudinal (sagittal), turning (torsion) and transverse (transversal) posture changes supporting the body yields.
  • DE 3025916 A1 shows a movable on a backrest bar suspended backrest, which consists of two horizontal Sections exist, the top section being the shape a "T”, and the bottom section has the shape of a "U”, and the "U” with its two legs the vertical part of the "T”.
  • the two sections are against each other pivoted on two sides of the backrest bar Bearings attached.
  • a spring band causes the two Sections are resiliently pivotable.
  • This known backrest only adjusts to sagittal movements of the User, and the assembly is relatively expensive.
  • backrests of the known type to improve in that it with modest effort and are therefore inexpensive to manufacture, and without further on conventional support structures for height-adjustable backrests of office chairs can be attached can.
  • the essence of the invention is that the storage of the both parts of the backrest shield is designed such that by simply exchanging a simple element, namely the bearing role, either just a sagittal, or but also additionally a tordale and transversal The backrest moves.
  • Fig. 1 shows the shield of a backrest, which consists of a upper part 1 and a lower part 2.
  • the parts 1,2 meet in the horizontal joint 3.
  • the backrest is suspended from the backrest bar 8, which is telescopic adjustable in height in the backrest shaft 15.
  • Backrest rod 8 and backrest shaft 15 have bores 19 Fixing the backrest height set in each case.
  • the parts 1.2 of the backrest shield are articulated over the Bearing parts 4.5 connected together.
  • a bearing rod 7 is stored, which is still suitable Openings of the bearing piece 9 is stored.
  • This stock 9 is attached to the backrest bar 8 and by means of a Bracket 13 secured.
  • the bracket 13 is pivotable in the Backrest bar 8 hooked in, and is on part 1 of Backrest plate by means of the screw-on bracket holder 14 attached.
  • the bearing piece 9 has on both sides of the backrest bar 8 Side panels 10 on. These side parts 10 have one hand Above stops, the upper part 1 of the backrest shield can concern. On the other hand, they have running down Cheeks on which the fixing block 16 is pivotally suspended is. This has a (not shown) nose, which in the holes 19 of the backrest bar 8 and the backrest shaft 15 can be locked. He also grips the backrest bar 8 and backrest shaft 15 and thus serves as a stop of the lower part 2 of the backrest shield.
  • FIG. 3 shows the view from FIG. 2, but with the left bearing open.
  • the bearing parts 4.5 consist of the Parts 1,2 connected bearing shells 11,12, and attachable Covering shells 17.18.
  • the inner bearing shells 11 are with connected to the upper part 1 of the backrest shield, the outer Bearing shells 12 are connected to the lower part 2.
  • the Bearing cups 11 are therefore the "upper bearing cup” Bearing shells 12 called “lower bearing shell”, accordingly the corresponding cover shells 17, 18. Are inside the bearing rollers 6.
  • the parts 1.2 of the backrest shield, the bearing parts 4.5, and the bearing piece 9 are preferably injection molded parts and are made of polypropylene or the stiffer polystyrene.
  • Bearing bar 7, backrest bar 8 and backrest shaft 15, and bracket 13 are made of metal.
  • the bearing rollers 6 can now also be made of polystyrene or some other rigid material. Then can the parts 1,2 of the backrest shield against each other around the bearings 4.5 swing, and the entire backrest shield around the im Bearing piece 9 bearing rod 7. The back follows only sagittal body movements.
  • the bearing rollers consist of an elastic one Material, especially rubber. Then the bearing rod 7 movable that the backrest also torsional or transverse movements can follow the user's back.
  • Fig. 1 the parts 1,2 of the backrest shield in reinforcing webs on, so that a Rib grid or a sandwich-like honeycomb structure arises.
