Definitions

  • the invention relates - according to the preamble of independent claim 1 - a seat and backrest assembly in seating, especially office chairs, which a seat plate, a seat support and a backrest support includes and wherein the seat plate in the area her front, knee-side edge with the seat plate carrier as well as in the area of its rear edge with the Backrest support is movably connected, wherein the backrest support (6) slidable on the seat plate carrier (3) is articulated.
  • This "synchronous work chair” takes place the adjustment of the inclination of the seat plate and the Adjustment of the inclination of the backrest support dependent from each other and is a complex, multi-part spring unit cushioned.
  • the object of the present invention is to provide a Seat and backrest arrangement in seating, in particular Office chairs, to propose, which is simple, includes few items and yet a high level of functionality and quality assured.
  • FIG. 1 shows a cross section through an inventive Seat and backrest arrangement, according to a first embodiment.
  • the seat plate 1 is in the area of its front, knee-side edge 2 with the seat plate carrier 3 via a spring means 4 - here in the form of a U-shaped leaf spring - connected.
  • a spring means 4 - here in the form of a U-shaped leaf spring - connected.
  • Embodiment could also include a spring means 4 in Form of one or more torsion springs (not shown) or other spring means, which allow the seat plate 1 opposite the seat plate carrier 3 in the area of its front, knee-side edge 2 movable and resilient to attach be executed.
  • a spring means 4 in Form of one or more torsion springs (not shown) or other spring means, which allow the seat plate 1 opposite the seat plate carrier 3 in the area of its front, knee-side edge 2 movable and resilient to attach be executed.
  • the seat plate 1 with the backrest support 6 movably connected.
  • This mobile Connection is accomplished via a first joint 7.
  • the backrest support 6 via a second joint 8 hinged to the seat plate carrier 3.
  • This second joint 8 includes one on each side of the seat support 3 each Roller 9, which is fixed here on the seat plate carrier 3.
  • the backrest support 6 has the two rollers 9 corresponding Guides 10, in which the rollers 9 slidably are arranged.
  • the rollers 9 also attached to the seat plate 1 and the recesses or other means for guiding the rollers 9 (Like rails and the like) arranged on the seat plate carrier 3 be.
  • This mechanism comprises a tongue 12, which with a Grid element 13 can be brought into engagement.
  • the tongue 12 comprises a grid pin 14, which engage between the teeth 15 of the grid element 13 can.
  • the grid pin 14 is attached to a piston 16, which arranged displaceably in a guide cylinder 17 is.
  • the guide cylinder 17 is at the bottom 18 of Seat plate 1 and the grid element 13 is on the seat plate carrier 3 attached.
  • the spring element 4 in the region of the front, knee-side edge 2 of the seat plate 1 acts like a joint between seat plate 1 and seat support 3.
  • the mobility This spring means 4 is the intervention of the Tongue 12 and its grid pin 14 on the grid element thirteenth blocked, because with it a stable connection between seat plate 1 and seat support 3 is created.
  • the tongue 12 also includes an activator rod 19 which supports the piston 16 connects with a spring element 20.
  • Am as a torsion spring trained spring element 20 engages an operating rod 21, which preferably at its end a control knob 22 has.
  • the control button comprises a cam 23, which is acted upon by a spring 24.
  • the Blocking mechanism be carried out completely different: z. can the tongue 12 slidably on the seat plate carrier 3 and the grid element be arranged on the seat plate 1. Also can the spring element 20 e.g. be formed as a leaf spring. Also the shape and arrangement of operating rod 21 and Control button 22 and the suspension 24 is at will a specialist, provided at least the functions described are guaranteed.
  • the torsion spring builds a tension in the opposite direction (see arrow in Fig. 2e) and pulls on the grid pin 14. This can but do not leave the grid element 13, because - because of the tension, by the spring element.4 or by the weight of the seated Person generated - the frictional forces between the teeth of the raster element 13 and the grid pin 14 to are large (Fig. 2e). Because of the suspension 24, which against presses the pre-selection, the prefix can not in his swing back to previous position.
  • FIG. 3 shows a seat and backrest arrangement according to the invention, according to a second embodiment.
  • This embodiment differs from the first in that a third joint 26 in the area of the anterior, knee-sided Edge 2 of the seat plate 1 is arranged and this seat plate connects to the seat plate carrier 3.
  • the already described Synchronous mechanism by means of which with a single or with several spring means 4 and the two 7,8 joints the seat plate 1 and the backrest support. 6 or the backrest 11 are cushioned is, by the third joint 26 not impaired.
  • the third joint 26 allows the third joint 26 the additional use of a Adjusting means 27, with which the spring force of the spring means 4 can be changed. This will be further down on hand Figure 4 explained in more detail.
  • the inventive seat and backrest arrangement shown here an additional seat depth adjustment.
  • the first joint 7 between seat plate 1 and backrest support 6 is also carried out slidably, the Backrest support 6 also moved relative to the seat surface 28 become.
  • a Body 29 includes, which in or on the backrest support 6 is arranged displaceably.
  • the backrest support 6 has for this purpose a guide member 30, the here is formed as a recess and in which the body 29th is slidably disposed.
  • the Backrest 11 adjusted to the seat 28 and held has the body 29 grid grooves 31, in which engages a lever 32.
  • the adjusting lever 32 is is arranged on a hinge on the backrest support 6 and is preferably permanently against the body 29 by a spring and thus pressed into one of the grid grooves 31. This is the seat depth adjustment lockable formed.
  • a seat and backrest arrangement according to the invention according to the first embodiment (see Fig. 1) equipped with such additional seat depth adjustment be (not shown).
  • FIG. 4 shows a seat and backrest arrangement according to the invention, according to a second embodiment, with a additional adjusting means 27, with which the spring force the spring means 4 can be changed.
  • the embodiment shown comprises a arranged on the seat plate carrier 3 Bearing plate 35, in which a adjusting bolt 36th is guided by a thread.
  • On the adjusting bolt 36 is a Knurl wheel 37 attached, with which the position of the adjusting bolt be changed by hand relative to the bearing plate 35 can.
  • the acting on the seat support 3 part of the Spring means 4 here the lower leg 38 of the spring means 4) permanently acts on the adjusting bolt 36, so that a Adjustment of the position of this adjusting a change the spring force of the spring means 4 causes.

  • the bearing plate is arranged inclined relative to the seat plate carrier and has a substantially perpendicular to the bearing plate extending Guide plate on.
  • One is essentially parallel to the guide plate extending adjusting spindle is rotatable attached to the bearing plate, pierces them and instructs its head a knob for turning the adjusting spindle on.
  • the adjusting spindle is opposite the guide plate stored.
  • a control body with appropriate Internal thread is in constant engagement with the External thread extending through this actuator body Adjusting spindle, so that when turning the adjusting spindle the distance of the Stellköpers from the bearing plate changes.
  • At least one roller is attached to the side of the adjusting body, which rolls on the guide plate and always together moved with the actuator.
