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 seat plate inclination between the seat plate and the seat support and a second gas spring for adjustment the backrest angle between the seat support and the backrest is effective and both gas springs can be blocked or unlocked by means of a handle.
  • Such a seat is known for example from DE-A-2 501 673. However, this document does not provide any further details regarding the function and operation of the handle.
  • a seat of the type mentioned is now expediently designed such that the inclination of the seat plate and the inclination of the backrest can be adjusted either independently of one another or simultaneously with the single handle.
  • valve actuation pins of the gas springs are provided at the ends assigned to the seat support and, preferably V-shaped, are arranged opposite one another and that as a handle a horizontal adjusting lever extending transversely between the valve actuation pins about a pivot point that is outside the straight connecting line lies between the valve actuating pins, is pivotally and vertically pivotably mounted on the seat support and engages with a wedge-shaped control body between the two valve actuating pins.
  • the blocking of the one gas spring for example the gas spring for the seat plate inclination
  • the blocking of the other gas spring can be released without unlocking the one gas spring when the adjusting lever is pivoted in the opposite horizontal direction so that it pushes in the associated valve actuating pin. If the adjustment lever is returned to the starting position, i.e. to the middle position between the two valve actuation pins, 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, which are movably arranged in the manner of a pair of scissors in a vertical plane containing the valve pin arrangement, are provided, which are fastened to the seat carrier, the adjusting lever reaching through the control arms and the control arms with their outside interact 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. For the rest, what has been said about the above embodiment applies to this embodiment.
  • the adjusting 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.
  • the gas springs remain unblocked and can therefore yield 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, one in the middle Arrangement of the valve actuating 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 to 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 adjustment lever is located at one end of the adjustment lever and the link through which the adjustment lever extends is provided on the side of the arrangement of the valve actuation 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 then ring-shaped in the area of the scissor-like control arms, and the scissor-like control arms are articulated at two spaced-apart pivot points, so that the pillar 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 just as well 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.
  • 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 is rotatable together with the seat plate 13 and the backrest 18 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 area and is pivotally mounted with its piston-side end on the seat support 12 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 to 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. 1, which can be displaced in the longitudinal direction of the respective gas spring and, when not under pressure, protrudes from the piston ends projecting inward beyond the bolts 22 and 26 . If the 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. However, when a back pressure exceeding the gas spring pressure is exerted, the gas springs 20, 24 shorten 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 for guiding the adjusting lever 32 is provided on the side of the seat support 12 opposite the pivot point 34, which will be discussed in more detail later.
  • two control arms 40, 42 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 outer control cams work with the valve actuation pins, while the inner control cams of the control arms work with the ring 36 of the adjusting lever 32.
  • 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 to the outside.
  • 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; that 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 upwards 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.
