Definitions

  • the invention relates to a chair, in particular an office chair, with a seat bracket that can be tilted in relation to the horizontal and one in sync with the inclination of the seat support in his Adjustable backrest support.
  • the present invention has for its object a Chair with a synchronous adjustment mechanism of the seat and to create the backrest that is less constructive than the solutions known since then.
  • the task is carried out with a chair of the type mentioned at the beginning solved according to the invention in that the seat support and Backrest support made of an elastic at least in some areas resilient component are formed and the seat support an essentially U-shaped area of the component consists of one of the legs of the U-shaped seat support is arranged on a chair column.
  • the seat support and backrest support are omitted assembly work required for conventional chairs.
  • the Entire chair consists of a few individual components that are quick can be assembled. Due to the U-shaped design of the seat support this gets the necessary flexibility.
  • the legs of the U-shaped seat support in their end region coupled to one another via a connecting element.
  • the connecting element can be elastic, so that an unimpeded but controlled transmission of the movement of the Seat support on the backrest support is possible.
  • the leading edge the base of the U-shaped part forming the seat of the chair Seat carrier can advantageously be flexible and on a guideway connected to the chair column be led. This is a lowering of the seat possible to the rear without changing the height of the front edge The seat changes, causing an uncomfortable pressure on the would lead the user's legs in the area of the hollow of the knees.
  • the leg of the U-shaped Seat carrier can also be pivoted to a limited extent about a horizontal axis be arranged on the chair column.
  • the seat support and the backrest support can be pivoted forward on the chair column to support the Back of the user even when the work posture is bent forward to support well.
  • the inclination of the seat support and the backrest support can also be locked will.
  • Devices for body weight-dependent adjustment of the Sensitivity of the synchronous adjustment on the backrest and Seat support can be arranged.
  • the Stiffness of the leg of the Seat carrier by means of a slidable along the leg Sleeve can be adjusted depending on body weight. By moving the sleeve becomes the bending zone of the leg in length varies and thus the stiffness of the leg is adjusted.
  • the chair can also lock the tilt of the seat and backrest support. Also the The depth of the seat can be adjusted.
  • the seat support 12 has a backrest support 11 on, which is formed in one piece with a seat support 12. That forming the backrest support 11 and the seat support 12 Component 13 is bent in a U-shape in the area of the seat support 12.
  • One leg 14 of the U-shaped seat support 12 is over a Bearing 15 connected to a chair column 16, which is in a base 17 is arranged adjustable in height.
  • the leg 14 of the U-shaped seat support 12 is over with the second leg 18 a connecting element 19 is elastically connected.
  • the seat support 12 has a flexible Zone 20 on. In this area the seat support 12 is on an arcuate guide track 21, which with the Chair column 16 is connected.
  • the leg 14 of the seat support 12 mounted on a lockable axis 22 on the chair column 16, which also allows pivoting of the seat support 12 to the front.
  • the two most extreme inclination positions of the chair 10 are shown in Fig. 3.
  • the seat support 12 is one Angle ⁇ can be lowered below the horizontal 30 and by an angle ⁇ can be raised relative to the horizontal 30.
  • the seat support 12 forms the seat support 12 with the Backrest support 11 has an angle ⁇ which is greater than that Angle ⁇ between the seat support 12 and the backrest support 11 in the rest position of the seat support 12, as shown in FIG. 2.
  • the front edge 20 of the chair 10 changes its height when Do not lower the seat support 12 below the horizontal 30.
  • the different inclinations of the seat and backrest support can be locked by means of a clamping device 31 will.
  • the synchronous adjustment depending on the body weight of the The user of the chair is the leg 14 of the U-shaped seat support 12 provided with a sleeve 23, which is along the leg 14 is displaceable (Fig. 4, 5). Is the sleeve 23, as in Fig. 4 shown pushed as far back as possible the bending area 24 of the leg 14 has its greatest extent.
  • the synchronous adjustment requires only a small amount Effort.
  • Fig. 6 shows a seat support 12 with a Possibility of seat depth adjustment. Because of the flexible Area 20 on the front edge of the seat support 12 can be the depth of the seat support 12 by, for example, a telescopic Extension of the guideway 21 by a maximum of Increase amount d.
