Definitions

  • a chair in particular a Office or work chair, with movable seat and mobile backrest, and arranged in the rear region of the seat cushion / arranged Stützelementbefest Trent / s (17) in or on each of which a flexurally elastic Supporting element (18) is attached, wherein along each support element (18) Compression spring elements (20) and extending over the spine width Shaping elements (21) each adjacent to each other alternately one above the other are arranged, which is characterized in that the lower Mold element (21) / or more of the lower mold elements (21) with each other by means of one or more arranged symmetrically to the center flexurally elastic / flexurally elastic stiffening element / stiffening elements (26) connected to one or more pivot lever (s) (27) is / are, which in one or more associated with the seat frame (5) and / or bearings (15) arranged on an adapter element (35) is pivotally mounted / are, wherein on the respective pivot lever (27) a Wegbeg
  • the adapter element (35) is fastened to the seat frame (5) and / or to the padding plate (8).
  • the backrests according to the invention without seat mechanism but also with any seat mechanism can be combined with both, as well as without armrests.
  • the adapter element (35) consists of two carrier bars (36), a connecting web (37) arranged between these carrier bars (36) and a molded part (38) arranged above the carrier bars (36) and the connecting bar (37). The rigid connection of these modules together ensures an aesthetically sophisticated, cost-effective and functionally reliable attachment of the functional assemblies on the adapter element (35).
  • the carrier bars (36) and the connecting web (37) from below, and the molded part (38) are rigidly connected to the pad plate (8) from behind.
  • a functionally reliable, aesthetically sophisticated attachment of the adapter element to the pad plate (8) is ensured.
  • the guide groove and / or the slotted guide are incorporated from the inside in each case in the side cheek of the seat frame. As a result, a risk of injury to the gear units of the chair is excluded.
  • a slot is arranged in which a slidably mounted in the slot, lockable clamping element is arranged, which arranged with a in the region of the intermediate plate on the clamping element Actuator in the clamped state acts on the intermediate plate and thus restricts the mutual relative movement between the intermediate plate and the seat frame. This makes it possible to limit the "swing mechanism" of the seat in this as the end position in any seat position.
  • a knob 24 for adjusting the Verstellhärte the Wegverstellmechanik and a mounted in a slot 31 of the side cheek 19 of the seat frame 5 clamping element 32 are further arranged for Endlagenbegrenzung the Wegverstellmechanik.
  • Behind the seat cushion two bending elastic, consisting for example of glass fiber rods support elements 18 are arranged symmetrically to the chair center axis on the seat frame 5.
  • At the flexurally elastic support elements 18 are adjacent to each other, for example made of elastic plastic (eg polyurethane foam) existing compression spring elements 20 and over the spine width extending form elements 21 arranged alternately one above the other.
  • the over the spine width extending mold elements 21 are preferably constructed in regions partially different geometrically.
  • These guide rollers 4 are slidably arranged at the front in the horizontal guide grooves 6 and rear in the arcuate slotted guides 7 of the side cheeks 19 of the seat frame 5.
  • the guide grooves 6 and the arcuate slotted guides 7 are incorporated from the inside in each case in the side cheek 19 of the seat frame 5, wherein in a side cheek 19 with a thickness of for example 24 mm, the guide grooves 6 and the slotted guides 7, for example, about 15 mm deep are incorporated.
  • the cushion plate 8 is arranged with the seat cushion.
  • a biasing element 9 is also attached, which can be actuated by means of the knob 24.
  • a spring element 11 is arranged between the biasing element 9 and a fastening element 10 arranged on the intermediate plate 3.
  • two support element fastenings 17 in the form of fastening bores 23 with or without insertion sleeves are arranged on the seat frame 5 (as far as the side cheeks 19) symmetrically with respect to the chair center axis.
  • the bending elastic consisting for example of glass fiber rods support elements 18 are arranged.
  • compression spring elements 20 arranged adjacent to each other from PUR foam sleeves and form elements 21 extending over the spine width, in some areas similar or also differently dimensioned, are arranged alternately one above the other on the flexurally elastic support elements 18.
  • the lower mold elements 21 are connected to each other by means of a symmetrical to the middle between the support members 18 arranged flexible elastic stiffening element 26 (see also Figure 1), which is arranged on a between the support elements 18 on the seat frame 5 on two bearings 15 by means of an axis 16 pivotally mounted pivoting lever 27 is.
  • On the pivot lever 27 is a Wegbegrenzungs- / biasing member 28 and the seat frame 5 with the Wegbegrenzungs- / biasing member 28 in operative connection passing stop 29 is arranged.
  • the stroke of Wegbegrenzungs- / biasing member 28 may, as shown in Figure 2, are adjusted relative to the stop on the seat frame 5 by means of an adjusting element 30.
  • the arrangement of the support member 18 causes the reclining anatomical, elastic support of the upper body can be realized in the lumbar region, by means of the adjustment 30 also the "hardness" of the lumbar support can be adapted to the user's needs, so that due to the inventive arrangement when leaning back a variable, anatomical, elastic support of the upper body is realized in the lumbar region.
  • a lockable clamping element 32 is arranged in the side cheek 19 of the seat frame 5 .
  • FIG. 3 shows the adjustment unit of the chair according to the invention in a further design in the perspective view obliquely from behind. On the pad plate 8, the adapter element 35 is attached.
  • This adapter element 35 consists of two carrier bars 36, a connecting web 37 arranged between these carrier bars 36 and a shaped part 38 arranged above the carrier bars 36 and the connecting bar 37.
  • the support bars 36 and the connecting web 37 are rigid with the pad plate 8 from below, and the molding 38 is rigidly connected to the pad plate 8 from behind.
  • At least the lower mold element 21 is / (but also several of the lower mold elements 21 can be connected to each other) by means of a centrally arranged flexurally elastic stiffening element 26 with the pivot lever 27 (to be).
  • In the adapter element 35 two projecting through the molding 38 in the support members 36 support element fasteners 17 are arranged. In these, the flexurally elastic support elements are attached.
  • each compression spring element 20 attached to the two support elements 18.
  • a pivot lever 27 is pivotally mounted on the molded part 38 of the adapter element 35 by means of a bearing 15 and an axis 16 arranged in this bearing 15.
  • a Wegbegrenzungs- / biasing element 28 is arranged at the pivot lever 27, at the connecting web 37 there is a stop 29 which comes into operative connection with the travel limiting / pretensioning element 28.
  • the stroke / the bias of Wegbegrenzungs- / biasing member 28 is adjustable relative to the stop 29 by means of an adjusting element 30.
  • an adjusting element 30 By means of the variation of the stroke / the bias of Wegbegrenzungs- / biasing element 28 is on the body height and thus on the body weight individually adjustable, anatomy-friendly, also dependent on the respective work attitude, optimal, elastic adjustment of the support function allows, so that in any arbitrary Sitting position regardless of the seat position individually adjustable elastic supported variation of the body opening angle can be ensured with elastic support in the lumbar region with simultaneous elastically supported torsion of the back.
  • the armrest support 12 and the seat mechanism 39 are further arranged.
