Definitions
- the present invention relates to seating, in particular Office swivel chair, with one foot, one of which is a central column runs upwards, the center column being variable in length and / or can be sprung with an am upper end of the center column fixed seat support, with a seat plate that is close to its front edge a horizontal axis pivotable with the seat support connected and by a spring arrangement with a above-loaded force, and with a Backrest that runs on at least one upward Lever is attached, which is under the seat plate in a first articulation point articulated with the seat support and at a distance from it articulated in a second articulation point is connected to the underside of the seat plate, wherein both articulation points parallel to the seat plate swivel axis Have pivot axes.
- Seating of the type mentioned is from the U.S. Patent 4,709,962 known. With such seating serves to support the backrest on the seat support and the lever hinged to the seat plate, a coupled To produce movement of the seat plate and backrest. Specifically, the coupling is that the backrest also when the seat plate is pivoted pivoted, but at a different angle than that Seat plate.
- the ratio of the swivel angle to each other is well known in the relevant market today Seating to a predetermined value in the area between about 1: 1.3 and 1: 2.5.
- DE 44 39 290 A1 describes a synchronous adjustment device known for office chairs, seating and the like, consisting of a seat part, a back part with a attached to or integrated into a back support Backrest and a fixed support frame, to which the seat part is articulated, the back support connected to the seat part and the support frame is and the seat part with an increase in the back inclination performs a pivoting movement.
- this adjustment device is used in at least one of the Swivel connections a link guide for the axis of rotation to overlay a displacement movement with the rotary movement around the pivot axis is provided.
- a link guide for the axis of rotation to overlay a displacement movement with the rotary movement around the pivot axis is provided.
- the disadvantage of this Synchronizing device viewed that the course the synchronous movements of the seat part and the back part is determined by the shape of the backdrop and no longer influenced by the user of the seating can be.
- Seating described a synchronous adjustment provided in such a way that when the Backrest back the seat plate to your rear End is raised and that vice versa when pivoting the backrest forward the seat plate in the back is lowered. This type of synchronous adjustment is no longer regarded as ergonomically favorable.
- the swivel angle of the seat plate and backrest is in this way the advantageous possibility of influencing of the swivel angle ratio created.
- Be useful for moving the first and / or second articulation point uses such technical means, that moving by the user of the seating can be made. This way everyone can Users of the seating furniture are comfortable and adapted to them Ratio of the swivel angle of the seat plate and Select and fix the backrest.
- first or the second articulation point is displaceable; if a particularly large one Variation range of the swivel angle ratio required , it may also be appropriate to use both articulation points to make it movable.
- Claims 6 to 8 are embodiments of the invention Seating described, in which the second articulation point is displaceable.
- the backrest can either rigidly attached to the upper, free end of the lever or about an axis parallel to the seat plate pivot axis hinged to the upper, free end of the lever be.
- the illustrated embodiment includes a seat 1, here an office swivel chair, one Foot 2, a seat support 3 connected to foot 2, a pivotable on the seat support 3 seat plate 4 and a backrest 5.
- the foot 2 comprises several, generally five arms 20, which each carry a roller 21 at their outer end. To the foot 2 also includes a center column 22, the extends centrally upwards and the length can be changed and / or sprung.
- the foot 2 is total of known construction and therefore only in the drawing shown in dotted lines.
- the seat support 3 is at one end 32 with the upper end of the central column 22 firmly connected, a Lift the seat support 3 upwards from the center column 22 is excluded, but a rotation of the seat support 3 around the central column 22 remains possible.
- the seat support 3 shows obliquely in its course above, with its outer end 34 connecting to the seat plate 4 by means of a pivot axis 43 which is in the horizontal direction parallel to the front edge of the seat plate 4 runs, produces.
- the pivot axis 43 is preferred realized by a corresponding joint; alternatively can also pivot axis 43 by using a flexible material can be realized, the corresponding one Pivotal movement of the seat plate 4 relative to his seat support 3 allowed.
- a spring element is provided, that the seat plate 4 with one pointing upwards Force preloaded.
- the backrest 5 extends upwards but no direct connection between the seat plate 4 and the backrest 5.
- the backrest 5 is rather via a lever 6 with the rest of the Seating 1 connected.
- the lever 6 is in two articulation points 63 and 64 on the one hand with the seat support and on the other other connected to the seat plate 4.
- the Articulation point 63 as in a guide 36 in the seat support 3 displaceable and lockable articulation element.
- the pivot point 64 is stationary on the underside 42 of the seat plate 4 attached, but one Displacement of the lever 6 in its longitudinal direction the pivot point 64 remains possible.
- the lever 6 At the pivot point 63 is the front one, the left one in the drawing End 61 of the lever 6 against movements in the longitudinal direction of the lever 6 set. To the right of the second articulation point 64 the lever 6 initially runs below the seat plate 4 backwards, i.e. to the right in the drawing, and then turns upwards. At its upper end 62 the lever 6 is connected to the backrest 5, wherein the backrest in the present exemplary embodiment 5 oscillating about an axis 56 with the lever end 62 connected is.
- the top 41 of the seat plate 4 and the front 51 of the backrest 5 are upholstered in the usual way as well as with a coating, e.g. made of fabric or Leather, provided.
- Figure 1a is a position in solid lines of the seating furniture 1 drawn with the seat plate 4 raised, in which a user of the seat 1 an erect Attitude.
- a user of the seat 1 By shifting his weight can the user of the seating 1 his posture change on the seating 1 and the seat plate 4 against the force of the above-mentioned spring element in a move diagonally backwards and downwards, which is drawn in dashed lines.
- the available swivel range of the seat plate 4 in the embodiment shown Figure 1a and also in the other figures of the drawing each 12 °.
- the articulation point 63 can be moved in its guide 36 1b, a state of the seating furniture 1 shows the articulation point 63 to the upper right End of the guide 36 is shifted and fixed there. Changed by this displacement of the pivot point 63 the length L to a smaller dimension. This downsizing the length L has the consequence that with the same pivoting the seat plate 4, here again by 12 °, the Backrest 5 now moves a larger swivel angle, in the present example now 28 °.
- Figures 2a to 2c show an embodiment of the seating 1, in contrast to the previous example 1a and 1b now the second articulation point 64 is changeable in its position during the first articulation point 63 is stationary on the seat support 3.
- FIG. 2a also includes this embodiment the seat 1, which is again an office swivel chair, one conventional foot 2, at the upper end of the seat support 3 is attached with its lower end 32.
- the Seat plate 4 is here again about the pivot axis 43 articulated or flexible with the same effect with the seat support 3 connected at its free end 34. Behind the Seat plate 4 extends backrest 5 again up.
- connection of the backrest 5 with the rest of the part of the seating furniture 1 again takes over a lever 6, the underneath the seat plate 4 on the underside 42 thereof runs and behind the seat plate 4 upwards is bent and there at its free end 62 the Backrest 5 carries. Again, there is a commuting Connection provided with an axis 56.
- a guide 46 is provided, along which the as Articulation element formed second articulation point 64 slidably and can be set in desired positions.
- the lever 6 runs through the second pivot point 64 through, with a relative movement between lever 6 and pivot point 64 in the longitudinal direction of the lever remains possible.
- the front end 61 of the lever 6 is in the first pivot point 61 around a horizontal axis parallel to Swivel axis 43 extends, movably mounted, otherwise but secured against movement in other directions.
- Figure 2c finally shows the seating 1 from Figure 2a and 2b now with a third position of the second articulation point 64, in which this as far as possible within its guide 46 is moved forward.
- the length L hereby almost reaches its minimum possible value, which leads to the fact that when the seat plate is pivoted 4 by 12 ° the backrest 5 performs a pivoting through 22 °.
- the guide 46 on the underside 42 of the seat plate 4 can be executed relatively easily with a great length there is a correspondingly large range of variation for the length L and therefore correspondingly larger Range of variation for the swivel angle ratio between Seat plate 4 and backrest 5.
- Even larger ranges of variation become possible if the range of variation the length L is additionally increased, either by Extension of guides 36 and / or 46 or by use of two sliding articulation points 63 and 64.
