Definitions

  • the invention relates to a mechanism for work chairs, in particular office swivel chairs, with synchronously adjustable inclination of the backrest and seat according to the preamble of independent patent claim 1.
  • CH-PS 647 665 brought a first improvement, in which a horizontally split backrest with a lower fixed backrest part and a resiliently arranged upper backrest part was proposed.
  • the design allowed the user to lean back a little more relaxed.
  • an actual relax position was not attainable because the backrest partially adapted to the respective usage situation, but the seat did not follow this adjustment harmoniously, but was arranged in a fixed position or could only be moved forwards and backwards.
  • a device of this type is described in DE-Gm 81 33 573 as a secretary's chair. It proposes a rocker which, by optionally installing the operating lever from two different sides, in one variant for a secretary's chair leaning forward from the vertical basic position and in the other variant leaning backwards from the basic position Executive chair, is suitable.
  • This device has the defect that not all chair settings or movement sequences typical in the office can be realized with it. Only the basic position and the negative inclination, respectively the basic position and the relax position are possible.
  • CH-PS 650 136 another mechanism for an office chair with a lockable negative inclination is known.
  • the backrest was divided horizontally in two and the upper part of the backrest was resiliently attached to its lower part.
  • the construction proposed here is very complex since two separate movement mechanisms - under the seat and in the backrest - are required.
  • this chair does not allow you to adopt or perform all sitting postures and movements.
  • gas springs are of crucial importance for the function of the mechanics.
  • Gas springs are widely used for the realization of the synchronous movement, some of which are coupled with helical pressure springs to optimize the movement sequence when adjusting the chair (cf. DE-OS 39 16 474, CH-PS 629 945).
  • gas springs are disadvantageous in several ways. First of all, these are relatively expensive, which costs the entire chair.
  • the gas pressure springs must be coupled with mechanical springs in order to achieve an advantageous movement sequence. This leads to further costs and complication of the entire construction.
  • gas pressure springs have a limited service life due to the seals that are subject to wear. Therefore, it has recently been proposed to use a specially designed torsion spring for the cushioning during the synchronous movement - as a problem-free mechanical solution (cf. WO 92/03072).
  • the invention has for its object to provide a mechanism that combines the advantageous tendency to straighten the human torso in the negative inclination of the seat, with the possible uses of a synchronous mechanism.
  • Stepless and consistent, all sitting postures should be able to be achieved gently in the office, on the hips and the back, self-adapting - simply by changing the posture or shifting the upper body weight without supporting and lifting the buttocks.
  • the device is intended to perform its function for the body weight range from approx. 45 kg to approx. 120 kg and to offer special options, for example for people with a very low body weight or with backbone problems.
  • the device in the interest of aesthetic design of the entire chair, the device must be made in a compact design.
  • the design and the components used must be efficient and inexpensive Allow serial production.
  • the chair mechanism 1 is plugged in its entirety onto the stand tube 2 of the chair frame, the stand tube 2 being seated in a receiving cone 3 of the chair mechanism 1.
  • the chair mechanism 1 consists of the seat support 4 - this is a movable seat support part 5 and a fixed one Seat support part 6 (for example, made of cast iron) - as well as from the seat support 7, the backrest support 8 and the torsion spring 9.
  • the backrest support 8 is articulated on the one hand with the negative inclination axis of rotation 10 and on the other hand on the seat-backrest support axis of rotation 11.
  • the negative inclination axis of rotation 10 runs horizontally and centrally through the receiving cone 3.
  • the negative inclination axis of rotation 10 and the seat backrest support axis of rotation 11 are parallel to one another;
  • the torsion spring 9 also extends parallel to it - its central axis is also the synchronous movement main axis of rotation 12 - and the front seat axis of rotation 13.
  • the seat support 7 is articulated on the one hand on the seat backrest support axis of rotation 11 with the backrest support 8 and on the other hand at the front seat pivot axis 13 articulated.
  • both driver plates 15 are arranged at a parallel distance, connecting both.
  • the drive tabs 15 have approximately the shape of a sheet metal angle, through the projecting leg of the seat axis of rotation 13 passes and through the corners of which the torsion spring 9 passes.
  • both the connections between the latter and the driver straps 15, as well as between the driver straps 15 and the front seat rotation axis 13, are rigid (for example by welding).
  • the second legs of the driver plates 15 are directed horizontally into the chair mechanism 1.
  • each leg end there is a tab recess 16 into which the nose 17 of a locking lever 18 can be pivoted for the synchronous operation.
  • the locking lever 18 is mounted on the locking lever axis 19.
  • a pair of helical compression springs 21 is arranged between the tongue piece 20 of the fixed seat support part 6 and the movable seat support part 5 located above it.
  • a locking lever 23 with a locking lug 24 is pivotally mounted on a locking lever axis 22 below the tongue piece 20.
  • the movable seat support part 5 is on the one hand - like the backrest support 8 - mounted on the negative inclination axis of rotation 10 and on the other hand rigidly connected to the torsion spring 9 passing through the receiving bores 25.
  • the seat support 4 is also possible to design the seat support 4 as a one-piece resilient component made from a leaf spring or from an elastic plastic body, the locking lever 23 then having to act on this one-piece seat support 4.
  • a smaller bore 26 extends through the fixed seat support part 6.
  • the actuating linkage 27 for the gas pressure spring (not shown) for adjusting the seat height projects out of the bore 26.
  • Figure 3 shows the chair in the basic position.
  • the user sitting there has an upright posture, such as during a meeting or sorting Files.
  • Figure 4 is the associated configuration of the chair mechanism 1.
  • the seat cushion on the seat support 7 runs practically horizontally; the backrest mounted on the backrest support 8 extends perpendicularly thereto.
  • the torsion spring 9 and the compression springs 21 are not loaded beyond their pretension.
  • the locking lever 18 for the synchronous sequence is not swung in; the locking lever nose 17 is not in engagement with the tab recess 16 and the locking lever axis 19 rests on the lower pin of the tab recess 16. Nevertheless, the locking lever 18 could be pivoted in this basic position (see the explanation for FIGS. 9 and 11).
  • the synchronous mechanism remains inactive in this basic position.
  • the user brings his body weight - in the vertical sitting position - so centrally onto the chair that the backrest is not deflected out of the "O" position.
  • the seated person does not press his back against the backrest and the force exerted on the backrest support 8 by the body weight bearing on the seat-backrest support axis of rotation 11 is compensated for by the pretensioning of the torsion spring 9.
  • the synchronous movement main rotation axis 12, the front seat rotation axis 13, the seat backrest support rotation axis 11 and the backrest support 8 additionally articulated on the negative inclination turning axis 10 are not rotated.
  • the span between the tongue piece 20 and the angled extension of the movable seat support part 5 below it is minimal, so that the locking lever 23 for the negative inclination, with its locking nose 24, cannot be pivoted under the tongue piece 20. If the negative inclination is activated, the movable seat support part 5 executes a downward pivoting rotary movement in the area of the compression spring 21 and the locking lever axis 22 located thereunder. Since the locking lever axis 22 is firmly connected to the movable seat support part 5, the widening span would finally allow the locking lever 23 to be pivoted in.
  • the chair mechanism 1 In the event of a change in posture or a shift in weight by the user, the chair mechanism 1, depending on the direction of the load, could tilt seamlessly from the basic position - without the locking lever 18 pivoted in - to the front, in the direction of the negative inclination, or to the rear, in the direction of the relaxed position.
  • Figure 5 shows the chair in the negative inclination.
  • the user sitting in it has a forward bent position, such as when writing.
  • Figure 6 is the associated configuration of the chair mechanism 1.
  • the seat cushion on the seat support 7 is tilted slightly forward, and the backrest also tilts forward.
  • the representation concerns the front end position of the negative inclination. However, all intermediate positions are infinitely variable, depending on the load caused by the weight shift.
  • the compression springs 21 are compressed to a maximum and the span - in the spring area - between the tongue piece 20 and the oblique extension of the movable support part 5 lying above it is narrowed to a minimum.
  • the opposite is the case with the span between the tongue piece 20 and the angled extension of the movable seat support part 5 underneath. This has increased to a maximum, so that the locking lever 23 with the locking lug 24 could be pivoted under the tongue piece 20 (see the explanation in this regard) 10 and 11).
  • Figure 7 shows the chair in the relaxed position.
  • the person sitting in it has assumed a reclined position, such as during a long phone call.
  • Figure 8 is the corresponding configuration of the chair mechanism 1.
  • the seat cushion on the seat support 7 is slightly raised at the front, but more clearly lowered at the rear. That is also inclined backwards Backrest.
  • the illustration illustrates the rear end position when relaxing. All intermediate positions are also steplessly possible here, depending on the pressure against the backrest as a result of the weight shift.
  • the synchronous mechanism is in operation when the relax position is maintained. Sufficient pressure from the user against the backrest causes it to pivot backwards and lower the backrest support 8 about the negative inclination axis of rotation 10, to which the backrest support 8 is also articulated. At the same time, the seat support 7 articulated on the seat backrest support axis of rotation 11 is pulled downward and further backward. This in turn has the consequence that the link plates 15 pivoted about the main synchronous movement axis of rotation 12 are pulled, as it were, by the articulated connection between the seat support 7 and the driver plates 15 on the front seat axis of rotation 13.
  • the driving lugs 15 are fixed (for example welded) to the front seat rotation axis 13 and are in engagement with the torsion bar 14, the increasing backward pivoting of the backrest is operated against the spring force that increases with the angle of rotation of the torsion bar 14.
  • FIG. 9 shows the locking lever 18 pivoted out of the “open” position, as a result of which the synchronous movement is blocked and the chair mechanism 1 is in the basic position. Swiveling into the negative inclination is possible from this position.
  • the option of locking the synchronous movement makes sense, e.g. for people with back problems who have to be prevented from leaning backwards.
  • FIG. 10 shows the possibility of locking the maximum negative inclination taken in by swiveling under the tongue piece 20 by means of the locking lever 23.
  • the entire setting range of the synchronous movement can be traversed from the locked negative inclination. It is only offset forward by the negative inclination angle and the rear end position is accordingly advanced by this amount.
  • the option of locking the chair in the negative inclination will be useful to very light-weight people, for whom it would always be associated with certain efforts to push the seat down against the compression spring 21 at the front.
  • both the synchronous movement is provided for very specific applications by pivoting the locking lever 18, as well as blocking the negative inclination by pivoting the locking lever 23.
  • the above-described synchronous mechanism with an integrated negative tendency combines all the positive findings previously used separately to significantly reduce the negative, damaging influences of long-term sitting.
  • all sitting postures that occur during office work are met according to modern medical and ergonomic requirements.
  • the creation of a chair mechanism with a range of motion from the negative tendency to the rear relaxation posture, with a mere shift of weight through the upper body posture of the user - without supporting the arms or lifting the buttocks - was ultimately only through inventive, completely new, conceptual processing and constructive implementation of the stress and movement sequences when sitting.
