Definitions

  • the present invention relates to a chair, in particular office swivel chair, with a seat support attached to a central chair column or several chair legs, with a seat plate carried by the seat support, with a backrest which is height-adjustable relative to the seat plate and with two side armrests which are height-adjustable relative to the seat plate.
  • the object of the present invention is therefore to create a chair of the type mentioned at the outset which avoids the disadvantages set out and in which in particular the height adjustability of the backrest and armrests is made possible with less construction effort, without this having a negative effect on the functionality and the appearance of the chair.
  • a chair of the type mentioned at the outset which is characterized in that it comprises two upward-extending lateral guide profiles, starting from the seat support or from the seat plate, and in that each guide profile contains a backrest guide and an armrest guide.
  • the number of guide profiles required is advantageously reduced to only two, the two guide profiles guiding and holding both the backrest and the two armrests in a height-adjustable manner. Since each guide profile contains both a backrest guide and an armrest guide, independent adjustment of the height of the backrest on the one hand and the armrests on the other is guaranteed. At the same time, however, a reduction in the number of individual parts of the chair and thus simpler and more economical production is achieved.
  • the backrest is designed as a back shell which is provided on its lateral edges with guide elements which are in guide engagement with the backrest guide in the guide profiles.
  • the design of the backrest as a back shell gives it a sufficiently high level of inherent stability and ergonomic shape so that the guide elements can be attached to the side edges of the backrest easily and sufficiently firmly and securely.
  • each armrest is designed with an essentially horizontal armrest and with an armrest support extending downwards and / or backwards from it, the armrest support being provided at its end facing away from the armrest with guide elements which engage in guide engagement stand with the armrest guide in the associated guide profile. This achieves a simple and stable construction of the armrests on the one hand, and their orientation and height also correspond to the ergonomic requirements of the chair user and can be easily adapted.
  • the guide profiles are hollow profiles which contain the backrest guide in their interior in the rear area and, parallel to this, the armrest guide in their front area.
  • This design of the guide profiles achieves an appealing and smooth outer appearance of the guide profiles, combined with sufficient stability to absorb the forces that occur.
  • the hollow profiles can be, for example, extruded light metal profiles, which enables cost-effective production with an appropriate design of the interior of the guide profiles.
  • the guide elements provided on the backrest in the backrest guides are preferably axially displaceable and lockable guide rods.
  • each armrest support engages through a profile slot in the guide profile and one in the armrest Guide axially displaceable and lockable foot has as a guide element. Since the load on the armrests is less than the load on the backrest, a foot is sufficient as a guide element for the armrest support, which foot only requires a relatively small axial length within the guide profile.
  • locking means for the armrest height adjustment which can be manually locked or released, are preferably provided on at least one of the two guide profiles or on the armrests. , 1st
  • the two guide profiles are combined to form a U-shaped component in the rear view of the chair, the U-bend of which the rear area of the seat plate and the U-legs formed by the two guide profiles point upwards.
  • FIG. 1 shows the essential parts of a chair in a side view
  • Figure 2 shows the chair of Figure 1 in a rear view
  • FIG. 3 shows one of the guide profiles provided on the chair in cross section along the line III-III in FIG. 1.
  • an office swivel chair 1 shown here comprises as essential parts a seat support 2, a seat plate 3 mounted thereon, a backrest 4 and two side armrests 5. Because the armrests 5 are congruently arranged here, only that armrest 5 facing the viewer is visible. From the underside of the seat support 2, a central chair column 20 extends downward, which is shown only in a small part here, and at the lower end of which, as is known per se, there is a base with castors.
  • the seat support 2 and the seat plate 3 are also of known construction.
  • each guide profile 6 includes the because it is designed as a hollow profile, with a backrest guide and an armrest guide inside.
  • the backrest 4 is designed as a dimensionally stable back shell and is connected at its two lateral edges 45 with a downward-pointing guide rod 46.
  • the guide rods 46 run in the backrest guide within the guide profiles 6 and are displaceable therein in their axial direction and can be locked in the desired displacement positions.
  • a locking button 69 is provided at the lower end of each guide profile, which, depending on the actuation, causes or locks the guide rods 46.
  • a bellows 47 surrounding the associated guide rod is attached between the upper end of each guide profile 6 and the backrest 4, which bellows is variable in length and thus adapts to any adjustment of the backrest 4.
  • the armrests 5 each comprise an essentially horizon ⁇
  • each armrest support 51 has a foot 56 which serves as a guide element and is in guide engagement with the guide profile 6.
  • the guide profile 6 has a slot on the side pointing to the right in FIG. 1, through which the armrest support 51 engages into the interior of the guide profile 6 and into the armrest guide 65 provided therein.
  • the foot 56 and thus the entire armrest 5 can be displaced and locked in the axial direction of the guide profile 6, a locking button 59 being provided for locking or releasing the locking on the lower part of the armrest support 51.
  • the locking means for the height adjustment of both the backrest 4 and the armrests 5 can be of a type and design known per se.
  • the respective upper end position of the backrest 4 and armrests 5 is drawn in solid lines in FIG. 1; in comparison, the respective lower end positions of the backrest 4 and armrests 5 are shown in broken lines.
  • the backrest 4 and the armrests 5 can be moved independently of one another and without mutual hindrance within the guide profiles 6 and locked at the desired height.
  • FIG. 2 of the drawing shows the chair 1 from FIG. 1 in a rear view, the seat support 2 with the chair column 20 running downwards being recognizable in the lower part of FIG. 2.
  • the lower part of the chair column 20 with the base provided there is not shown.
  • the two guide profiles 6 can be seen, which, as FIG. 2 clearly shows, are connected to one another to form a uniform, U-shaped component.
  • a profile forming a U-bend 60 runs between the lower ends of the two guide profiles 6 and is connected to the seat support 2 in its central region.
  • the seat support 2, which is not shown in detail here, can be equipped with a so-called synchronous mechanism, which enables the seat plate 3 to be pivoted while simultaneously pivoting the backrest 4.
  • the connection of the guide profiles 6 to this synchronous mechanism takes place via the U-bend 60, so that the mechanical connection here is particularly simple.
  • each guide profile 6 At the upper end of each guide profile 6, one of the bellows 47 is again recognizable, to which the side edges 45 of the backrest 4 are connected upwards.
  • the backrest 4 In Figure 2, the backrest 4 is in her shown lower end position, so that the bellows 47 are compressed here.
  • the guide rods 46 connected to the side edges 45 run through the bellows 47 into the guide profiles 6 and are guided invisibly therein.
  • the armrests 5 are in engagement with the guide profiles 6 on the side facing away from the viewer in FIG.
  • Figure 3 shows in cross section along the line III - III in Figure 1, one of the two guide profiles 6.
  • the guide profile 6 is a hollow profile, for example an extruded aluminum profile. Inside it has two guides, namely in its rear, i.e. in Figure 3 left area a backrest guide 64 and in its front, i.e. an armrest guide 65 in the right area in FIG. 3.
  • the guide rod 46 runs through the backrest guide 64, which is also cut here and is firmly connected at its upper end to the side edge 45 of the backrest 4, as shown in FIGS. 1 and 2.
  • the foot 56 is guided, which is forwardly, i.e. in Figure 3 to the right facing profile slot 66 with the armrest support
  • the foot 56 can be moved together with the rest of the armrest in the axial direction of the guide profile 6 in the armrest guide 65 and can be fixed in desired positions in order to adapt the height of the armrest 5 or its armrest 50 to the needs of the respective user of the chair 1.
  • the chair 1 can be designed either with or without armrests 5 without great effort.
