Definitions

  • the present invention relates to a chair with synchronous mechanism, in particular an office swivel chair.
  • High-quality office chairs are also often equipped with a so-called synchronous mechanism, by means of which the seat and backrest together in a correlated movement pivot backwards and downwards when leaning back.
  • a chair with synchronous mechanism is eg in the DE 196 40 564 A1 described.
  • a person sitting on the seat is guided from a forward posture by shifting his weight to a reclining posture where relaxed sitting is possible.
  • the seated person In the forward position, the seated person typically assumes a nearly horizontal seating position so that the upper body forms a substantially right angle with respect to the thighs.
  • the pelvis in this sitting posture tends to turn backwards so that so that the natural S-shape of the spine becomes a so-called "round-back posture", which permanently burdens the intervertebral discs in the lumbar spine.
  • German utility model DE 75 32 885 U1 and the DE 20 2005 010 944 U1 describe Wegneigeverstellmechanismen using a gas spring or a bottom-acting against the seat spring.
  • the springs must here permanently absorb the entire load of a person sitting on the seat in the loaded state.
  • These (gas pressure) springs must be designed correspondingly complex so that they can reliably absorb the load for the life of the office chair, ie without significant material fatigue.
  • German patent DE 10 2008 042 973 B3 describes a further mechanism for seat tilt adjustment, in which the return function, in which the seat is reset to the starting position, is provided by a comparatively small spring-elastic element.
  • the recording of the force acting on the seat in the loaded state is not collected here on the elastic element, but rather on engaging in corresponding toothed rails gears, which is provided in a dedicated guide rail.
  • This type of seat recliner has been found to be very effective, especially in terms of reduced material and part cost and enduring reliability.
  • the present invention has for its object to provide a more comfortable seat tilt adjustment.
  • a chair is provided with a synchronous mechanism, in particular an office swivel chair, with a backrest, with a seat having a seat surface, a seat support and an adjusting mechanism, with a device for seat tilt adjustment, over which the seat is at least partially tilted in the vertical direction, with a synchronizing mechanism, which is coupled to the backrest and the seat and over which the backrest is pivotable relative to the seat in the horizontal direction to the rear, wherein the synchronizing mechanism is designed such that the device for seat tilt adjustment disables in a reclined state of the backrest is.
  • a forwardly inclined seat remains tilted slightly forward even when the backrest is pivoted backward. This is sometimes a bit uncomfortable for a person sitting on the office swivel chair, because then no longer the same predetermined angle between the upper body and thigh is present.
  • a relaxed sitting position is often more important to a seated person than a predetermined angle of the thighs, as is required, for example, during lordosis-relaxed upright sitting during work.
  • the idea underlying the present invention is now to deactivate or block the seat tilt adjustment when the backrest is pivoted backwards. If a seated person leans his back against the backrest and thus pivots the backrest to the rear, the seat is no longer inclined forward, but pivots about a fictitious axis of rotation slightly upwards and in the direction of the backrest. This reduces the distance between the pelvis and lumbar support so that the thighs have a better angle to the upper body or spine. Overall, so the discs of the lumbar spine are relieved, allowing a more relaxed sitting.
  • the synchronizing mechanism is designed such that the device for adjusting the seat inclination is deactivated or blocked only in a fully reclined state of the backrest, in particular completely deactivated. This is advantageous because it does not swing back upwards with a slight swinging backwards the seat and swinging back up when swinging back.
  • the synchronous mechanism includes a shift gate, which has a locking hole. Further provided on the pivot, spring force acted upon locking hook is provided, which is displaceable, for example by spring force in the axial direction of an axis of the rotary joint. Finally, a rigidly coupled to the locking hook locking bolt is provided, which in alignment Position is displaced into the locking hole and locked in this position, the device for seat tilt adjustment and thus deactivated.
  • the shift gate is rigidly coupled to the rotary joint and arranged such that the introduced in the locking hole locking bolt acts as a driver and entrains the locking hook in the non-hooked state.
  • the seat support When taking along, then the seat support lifts up relative to the backrest something.
  • the locking hook on a hook over which the locking hook on the housing of the seat support is hooked in such a way that a take away of the locking hook is blocked by the shift gate. In this state, for example, then the seat tilt is active and the seat can be tilted forward.
  • the synchronizing mechanism further comprises a confirmation mechanism which has an actuatable via an actuator spring element, which is resiliently coupled to the locking hook and over which the locking hook and thus the locking pin in the axial direction in the locking hole is displaceable.
  • the actuating element is coupled via a Bowden cable with a push-push switch, which in turn is coupled via a jumper wire with the locking hook.
  • the actuating element is coupled via a Bowden cable directly to the locking hook and / or the spring element. Conceivable, however, would be other switching elements with the same or similar properties.
  • the locking bolt and the locking hole are aligned in the event that the synchronizing mechanism is activated and thus the backrest is moved backwards, the locking bolt and the locking hole to each other, so that the locking pin to block the seat tilt adjustment spring loaded in the locking hole can slide.
  • the spring loading can be realized in a very elegant manner by means of a mounting device coupled to the locking hook and thus with the locking bolt compression spring.
  • the locking bolt and the locking hole can also be aligned with each other, if the Wegvorne Trent is activated.
  • the chair support is coupled to the seat support via a front, stationary mounted swivel joint and a rear, movably mounted in a slotted guide pivot, wherein the rear hinge is fixed in the inclined position in a lower region of the slotted guide and in the starting position in an upper starting position of the slotted guide is located.

  • the second functionality that is, the inclusion of the force acting on the seat in the loaded state, according to the invention is no longer collected on the elastic element, but rather on engaging in corresponding toothed rails gears.
  • This toothed rail is provided according to the invention in a specially provided guide rail.
  • a respective toothed wheel is here arranged to be movable vertically in a guide rail assigned to it, wherein the corresponding toothed rails likewise have a vertical orientation within these guide rails. In this way, a very effective and beyond a mechanically very stable seat tilt adjustment is possible.

  • the spring force of the resilient element is dimensioned such that, for example, in a horizontal sitting position, the resilient element has a greater spring force than at a tilted relative to the horizontal seating position.
  • a maximum spring force in the horizontal sitting position of about 45 N is caused by the resilient element, whereas this spring force at a z. B. by a few degrees inclined seating position only about half, for example, 25 N is.

  • the z. B. corresponds to the initial position of the seat, the elastic element is not or only slightly stretched.

  • the adjusting mechanism 20 also has a synchronizing mechanism for the backrest adjustment.
  • This synchronizing mechanism comprises in the present embodiment, a locking hook 91 with rigidly attached thereto locking bolt 92, compression spring 93 and a shift gate 94.
  • an actuating button 95 is provided, which via a Bowden cable 97 (in Fig. 8 not shown) is coupled to a push-push switch 96.
  • the push-push switch 96 is connected via a biasable jumper wire 98 (in Fig. 8 not shown) coupled to the locking hook 91 and the compression spring 93.
  • the synchronizing mechanism provides a hole 99 for insertion of the locking bolt 92, which is provided in the shifting gate 94 and into which the locking bolt 92 can be inserted provided that these are aligned with one another.
  • Fig. 9 shows a section of the in Fig. 8 illustrated chair according to the invention in the region of the adjusting mechanism 16 according to the invention with attached backrest support 15th Fig. 9 in particular shows the seat 11 Fig. 8 in the assembled state in a perspective view, but without the seat surface 11A, to thereby better represent the individual elements of the adjustment mechanism 16 according to the invention and their interaction.
  • the Fig. 9A and 9B show a side view and a back side view of the section of the chair 10 according to the invention Fig. 9 Here, the seat 11A is shown.
  • the locking hook 91 is mounted on the hexagonal shaft 33 and can thus rotate about the hexagonal shaft 33.
  • the locking hook 91 has a hook 91A on its free upper side. This hook is hooked in the starting position of the locking hook 91 at a corresponding point of the seat support 14.
  • the locking pin 92 is rigidly coupled to the locking hook 91 and thus rotates in the event of rotation of the locking hook 91 with this.
  • On the hexagonal shaft 33 is also a shift gate 94 with locking hole 99 rigid, so firmly attached.
  • the actuating button 95 is connected to the backrest adjustment via a Bowden cable 97 with the push-push switch 96.
  • the push-push switch 96 is in turn coupled via a jumper wire 98 with the locking hook 91 with locking pin 92.
  • the jumper wire 98 is coupled to the locking hook 91 or the compression spring attached thereto such that in the event of actuation of the actuating button 95, the locking hook 91 is displaced along the hexagonal shaft 33. This shift takes place in the example shown resiliently using the compression spring 93.
  • the attached to the locking hook 91 and thus firmly coupled with this locking bolt 92 along the hexagonal shaft 33 is moved. If the locking pin 92 is aligned with the provided in the gate cam 94 bore 99, it is pushed by spring force of the compression spring 93 into the locking hole 99, whereby the seat tilt mechanism is locked.
  • FIG. 9A and 9B Reference numerals 100, 101 denote the stationary front pivot point and the rear pivot point, respectively.
  • the rear pivot 101 is movable and can be moved up and down in the slotted guide.
  • the locking pin 92 is mounted in the rear seat arm (rear pivot axis 101) and is laterally displaced with the locking hook 91. In the case of a counterclockwise rotation of the gears 22a, the seat support 14 and the seating surface 11A applied thereto rearwardly rear, thereby creating the seat inclination.
  • the push-push switch 96 is actuated via the Bowden cable 97, wherein the push-push switch 96 holds this position.
  • the jumper wire 99 is triggered, whereby the hook 91A of the locking hook 91 compression spring applied on the axis of the hexagonal shaft is displaced until the hook 91A, the seat support 14 releases.
  • the coupled via the gear 22A kinematically with the seat support 14 hexagonal shaft 33 is thus freely rotatable.
  • the two elastic elements 26 designed as tension springs 26 pull the seat support 14 into the upper position by the rotational movement of the toothed wheels 22A.
  • the 10A to 10C show partial schematic side views of the chair according to the invention to explain the function of the synchronous mechanism according to the invention.
  • Reference numeral 102 here denotes the (lordosis) supporting point of the back of a seated person on the backrest element 18 of the backrest 12.
  • the backrest 12 is fastened to the adjusting mechanism 16 via a lever arm-like fastening interface 90 of the backrest support 15.
  • This adjustment mechanism 16 includes the slotted guide 104, along which the hexagonal shaft 33, which is part of the seat support 14, is movable.
  • Fig. 10A shows the chair 10 with inactive seat pitch adjustment mechanism and inactive seat adjustment mechanism.
  • the seat support 14 with padded seat surface 11A provided thereon is mounted so as to be fixedly rotatable on the adjustment mechanism 16 at a front rotation axis 100.
  • the rear pivot axis 101 is movable and can be moved in the slotted guide 104 up and down.
  • the rear axis of rotation 101 is formed by the hexagonal shaft 33 in the example shown.
  • the seat surface 11A is in a substantially non-inclined, horizontal starting position.
  • the rear axis of rotation 101 is located in the upper region of the slotted guide 104.
  • Fig. 10B shows the chair 10 in a situation in which a seat tilt is actuated.
  • the backrest adjustment is not actuated.
  • the seat surface 11A is inclined at a predetermined angle, for example 4 °, from the home position.
  • the seat carrier 14 is thereby rotated about the front axis of rotation 100 counterclockwise, whereby the seat support 14 pivots due to the degree of freedom of the seat support 14 in the region of the rear axis of rotation 101, that is due to the slide guide 104, at least partially upwards.
  • This upward pivoting results from the fact that the slotted guide 104 is moved upward relative to the rear axis of rotation 101.
  • Fig. 10C shows the chair 10 in a situation in which a seat inclination and the strictlylehnenverstellmechanismus (ie the synchronizing mechanism) are actuated.
  • the seat tilt adjustment is blocked or deactivated when confirming the mechanism of the backrest adjustment, for example, analogous to the above with reference to Fig. 9 to 9B explained.
  • the seat support 14 is pulled down along the sliding guide 104, whereby the seat surface 11A due to the synchronizing mechanism something to the backrest 12, or rather closer to the support point 102, passes.
  • the position of the seat surface 11A to the support point 102 of the backrest element 18 thus substantially corresponds to the state without activated seat tilt.
  • the support point 102 of the backrest 12 is thus optimal in relation to the seat surface 11A.
  • FIGS. 11 to 12B show a further embodiment of a chair 10 according to the invention. It is a question of a large part of the chair 10 according to the FIGS. 8 to 9B same embodiment, which is why in the following only the differences will be discussed.
  • FIGS. 11 to 12B differs in particular in that the actuating button 95 is coupled via a Bowden cable 111 directly to the locking hook 110, this represents an advantageous number of components reduced construction.
  • a cover 112 is provided, which is formed with a bearing 112 A for the outer shell of the Bowden cable.
  • a compression spring 113 is provided between the cover and the locking hook 110.
  • the Bowden cable 111 is coupled to the locking hook 110 or the pressure spring 113 attached thereto in such a way that, in the event of actuation of the actuating button 95, the locking hook 110 is displaced along the hexagonal shaft 33. This shift takes place in the example shown resiliently using the compression spring 113.
  • the attached to the locking hook 110 and thus firmly coupled with this locking pin 92 along the hexagonal shaft 33 is moved. If the locking pin 92 is aligned with the provided in the gate cam 94 bore 99, it is pushed by spring force of the compression spring 113 into the locking hole 99, whereby the seat tilt mechanism is locked.
  • the actuating button 95 is actuated in the unloaded state of the seat 11 and the seat 11 or its seat surface 11A is subsequently pressed downwards.
  • the locking hook 110 is viewed via the Bowden cable 111 from the sitting direction or in perspective Fig. 12B moved to the right.
  • the locking of the locking bolt 92 is released in the shift gate 94.
  • the seat support 14 and seat 11A are then movable to a lower position by loading on the seat. In this case, the hook 110 A is guided via an insertion bevel in a hooked position with the seat support 14.
  • the operating button 95 is pressed briefly in the unloaded state of the seat 11. Characterized the locking hook 110 is moved over the Bowden cable 111 in the seat direction to the right, whereby the hook 110A, the seat support 14 releases.
  • the tension springs 26 rotate the gears 22, 22A about the hexagonal shaft 33 fixedly rotatable within the adjustment mechanism 16 to a position in which the gears 22, 22A pivot the seat support 14 upwardly about the front rotation axis 100 due to the meshing engagement, thereby increasing the seat tilt of the seat surface 11A is reached.
  • the compression spring 33 then pushes the locking bolt 92 into the locking hole 99 of the shift gate 94 that is aligned in this position.
  • the two gears 22, 22A are non-rotatably coupled to the shift gate via the continuous hexagonal shaft 33.
  • the rotational degree of freedom of the gears 22, 22 A is set after insertion of the locking bolt 92 into the locking hole 99. Due to the toothing of the seat support 14 is then also determined in this position.
  • the invention does not necessarily relate to swivel chairs and / or office chairs, but can also be used advantageously in any other chairs with synchronous mechanism, seat tilt adjustment and backrest adjustment.
  • the present invention is not necessarily limited to the above concrete construction of a Wegneigeverstellmechanismus. Rather, it would also be conceivable on the crossbar and providing a second vertical To dispense with guide rail, although this would be less advantageous, in particular for stability reasons.
  • the lock on a spring-loaded locking pin by means of operation of a Bowden cable with or without overload protection is beneficial, of course, can also use a different locking option.
  • three different seat heights can be adjusted by a locking device of the guide lever is locked in each case at three different horizontal positions.
  • only two adjustable seat inclinations or more than three adjustable seat inclinations would be conceivable.
  • the construction of the guide rails and the gears can of course vary without departing from the subject invention.
  • the crossbar and the corresponding recesses in the gears need not necessarily be hexagonal, but may also be square, triangular, polygonal or about round or oval.
  • the interaction between the locking bolt and the locking hole can also be reversed without deviating from the subject matter of the invention.
  • the locking hole would be provided on the locking hook and the locking bolt attached to the shift gate.
