Definitions

  • the invention relates to a seat, in particular an office chair, with a seat plate arranged on a seat support and adjustable in inclination and a backrest adjustable in inclination.
  • a first gas spring for adjusting the inclination of the seat plate between the seat plate and the seat support and a second gas spring for adjusting the inclination of the backrest between the seat support and the Backrest is effective that the valve actuation pins of the gas springs are provided at the ends assigned to the seat support and are arranged in a V-shape opposite one another and that a horizontal adjusting lever extending transversely to the V-shaped arrangement of the valve actuation pins around a common pivot point, which is outside the straight connecting rings lies between the valve actuation pins, is pivotally and vertically supported on the seat support and engages with a wedge-shaped control body between the two valve actuation pins.
  • the blocking of the one gas spring for example the gas spring for the inclination of the seat plate
  • the blocking of the other gas spring can be released, for example to adjust the backrest inclination, without unlocking the gas spring when the adjusting lever is pivoted in the opposite horizontal direction so that it pushes in the associated valve actuating pin.
  • the adjustment lever is in the starting position, i.e. in the middle position between the two valve actuations donate, returned, both gas springs are blocked again and the seat plate or the backrest remain in the position they were in before the associated gas spring was blocked.
  • a second embodiment which is alternative to the above construction, instead of the wedge-shaped control body, two control arms are provided which are movably arranged in the manner of a pair of scissors in a vertical plane containing the valve pin arrangement and which are fastened to the seat carrier, the adjusting lever reaching through the control arms and the outside of the control arms cooperate with the valve actuation pins.
  • the function of the control body, which grips like a wedge between the two valve actuation pins, of a vertical pivoting of the adjusting lever is thus taken over by the two control arms, which spread out when the adjusting lever is pivoted vertically and in this way act on the valve actuating pins simultaneously.
  • the adjusting lever is pivoted horizontally, only one or the other control arm and thus only one or the other valve actuating pin is moved. Otherwise, what has been said about the above embodiment applies to this embodiment.
  • the adjustment lever can now be locked in its vertical swivel end position, that is to say in the position in which both valve actuation pins are acted on. Since the gas springs remain unblocked in this case and can therefore give way or follow, depending on how the posture is changed, a dynamic sitting position is achieved.
  • a guide is expediently provided for guiding the adjusting lever.
  • This can be plate-shaped and a horizontal, parallel to the arrangement of the valve actuating first guide slot at the level of the basic position of the adjusting lever, in which the valve actuation pins are not acted upon, and starting from the horizontal guide slot have a central to the arrangement of the valve actuation pins and vertically extending second guide slot.
  • the link can consist of an elastic material, preferably plastic, and the vertical guide slot can have a constriction in its end region facing away from the horizontal guide slot, with incisions from the vertical guide slot / Extend away from either side of the neck.
  • the incisions which must have a certain width for the necessary play, have the task of making the constriction area flexible. It is readily understandable that the tabs created by the constriction, on which the constriction is formed, are so flexible that they can be pushed away by the adjusting lever protruding through the guide slot with increased application of force, so that the adjusting lever is guided to the end of the guide slot where it is then locked by the recessed constriction.
  • pivot point of the pivotable adjusting lever is at one end of the adjusting lever and the link through which the adjusting lever extends is provided on the side of the arrangement of the valve actuating pins opposite the pivot point.
  • the second embodiment of the invention is particularly important when it is, for example, an office chair with a single, centrally arranged support leg.
  • the adjusting lever is annular in the area of the scissor-like control arms, and the scissor-like control arms are articulated at two pivot points located at a distance from one another, so that the supporting leg can extend through the ring of the adjusting lever and between the pivot points of the control arms .
  • the support holding the backrest extends under the seat plate and is pivotally fastened there in the central region to the seat support about a horizontal pivot axis, about which the seat plate can also be tilted, and are the first gas spring at the front edge of the seat plate and on the seat support and the second gas spring on the seat support and on the backrest support in the rear area lying below the seat plate each articulated.
  • the gas springs therefore assume a V-shaped position.
  • the wedge is not effective in the vertical direction but in the horizontal direction.
  • the scissors which can also open in a horizontal plane instead of opening in the vertical plane.
  • the adjusting lever must be displaceable in its horizontal longitudinal direction in both cases. The horizontal swiveling is retained. If these embodiments are also structurally much more complex, the same effects can nevertheless be achieved with these embodiments.
  • the office chair shown in the drawing has a standpipe 10 which extends into a seat support 12, which is only indicated schematically by dashed lines, and is connected to it in a manner not shown in more detail.
  • a seat plate 13 is arranged to be pivotable about a horizontal pivot axis 14 which is mounted on the seat support 12 and extends essentially above the standpipe 10.
  • An L-shaped backrest support 16, as shown in FIG. 1, can also be pivoted about the same pivot axis 14 and carries the backrest 18 on its upwardly projecting leg.
  • the arrangement can be made in a manner known per se such that the seat support 12 together with the seat plate 13 and the backrest 18 is rotatable around the standpipe 10.
  • a first gas spring 20 is articulated with its cylinder-side end on the underside of the seat plate 13 in its front region and is pivotally mounted on the seat support 12 with its piston-side end about a bolt 22.
  • a second gas spring 24 engages with its cylinder-side end on the backrest support 16, while its piston-side end is fastened on the seat support 12 so as to be pivotable about a bolt 26.
  • the gas springs 20, 24 are then arranged in a V-shape with respect to one another.
  • the gas springs 20, 24 each have a valve actuating pin 28, 30 on their piston-side ends, as shown in FIG.
  • valve actuation pins 28, 30 are acted upon, that is to say pressed into the piston ends, the blocking in the gas springs 20 and 24 is released, so that these expand and adjust the inclination of the seat plate 13 or the backrest 18.
  • the gas springs 20, 24 are shortened and the seat plate and the backrest tilt in the opposite direction. If the valve actuation pins 28, 30 are not acted upon and the gas springs are thus blocked, their length cannot be changed, so that the inclination of the seat plate 13 and the backrest 18 is retained regardless of the respective load.
  • an adjustment lever 32 is mounted on the seat support 12 so that it can be pivoted vertically and horizontally about a pivot point 34.
  • the adjusting lever 32 extends essentially in the horizontal direction transversely to the V-shaped arrangement of the gas springs 20, 24 and is formed in its area lying between the valve actuation pins 28, 30 as a rectangular ring 36 through which the standpipe 10 extends.
  • a link 38 is provided for guiding the adjusting lever 32, to which later in detail is received.
  • two control arms 40, 41 are also provided which can be pivoted on the seat support 12 about horizontal axes 44, 46 extending transversely to the V-shaped gas spring arrangement.
  • the axes 44, 46 lie above the pivot point 34 of the adjusting lever 33, and the control arms 40, 42 extend substantially vertically downwards, the control arm 40 between the valve actuation pin 28 and the ring 36 and the control arm 42 between the ring 36 and the Valve actuating pin 30 passes through.
  • the external control cams work with the valve actuation pins, while the internal control cams of the control arms work with the ring 36 of the adjusting lever 32.
  • the control arms 40, 42 are spread when the ring 36 is lifted vertically, so that the control arms act on the valve actuation pins 28 and 30 of the gas springs 20, 24, whereby the gas springs are unlocked. With a horizontal movement of the ring 36, either only one or the other control arm 40 or 42 is deflected, depending on the direction in which the adjusting lever 32 is pivoted, so that only one or the other valve actuating pin 28 or 30 is acted upon while the other remains unaffected.
  • the lower ends of the control arms 40, 42 are each offset outwards, as shown in Fig. 3, so that the ring 36 when it is in a central Position between the lower ends of the control arms 40, 42, neither engages on one control arm nor on the other control arm and thus none of the valve actuation pins 28, 30 is acted upon by the control arms.
  • the adjusting lever 32 extends through the link 38, which is essentially plate-shaped, and, as shown in FIG. 4, is provided with a specially designed opening which is described in more detail below.
  • the breakthrough includes a horizontal guide slot 48 for the horizontal movement of the adjusting lever 32 in the area in which the ring 36 of the adjusting lever is located between the ends of the control arms 44 and 46 which are offset outwards.
  • a further guide slot 50 which has a constriction 52 in its upper end region, extends centrally and vertically upward from this horizontal guide slot 48. Before and after the constriction 52, incisions 54 are provided on the side of the guide slot 50 and in each case bend upwards and have a certain width.
  • Flaps 56 are formed between these incisions 54 and carry the projections forming the constrictions 52. Since the backdrop 38 also consists of a resilient plastic material, the following effect is achieved with this design. If the adjusting lever 32 is moved upward in the vertical guide slot 50 starting from the horizontal guide slot 32, the hand operating it experiences a counterforce when the adjusting lever comes into contact with the constriction 52. In this position at the latest, the two valve actuation pins 28 and 30 are also acted on, as described above. If the adjusting lever 32 is then pressed further upwards with increased effort, the flaps 56 deflect laterally, and the adjusting lever 32 comes behind the constriction 52, where it is held in place by the flaps 56 returning to their original position.
  • the present invention has shown a 3-way mechanism which allows very simple and convenient handling.
