Definitions

  • the present invention relates to improvements to office chairs, and it relates more particularly to improvements to the adjustment and control systems of the various movable and / or deformable elements of an office chair.
  • An office chair essentially consists of a fixed base on which is mounted, generally rotary, an assembly formed by a seat and a back, which are generally adjustable and / or deformable to ensure the comfort of the user, depending on its size, conformation and working conditions.
  • patent WO-A-81/03605 and French patent FR-A-2 460 648 each describe a chair whose adjustment of the seat height and the inclination of the backrest are controlled by a single rotary member, namely a cam, acting according to its angular position on one or the other of two valves equipping two pneumatic cylinders determining said adjustments.
  • This control member being unique, it does not allow the user to differentiate one or the other setting.
  • European patent EP-A-385,473 describes a seat having height and tilting tension adjustment systems, which are controlled by two separate elements located in the same place. However, there there are no means for adjusting the inclination which, being cut off from the aforementioned adjustment means, could be actuated in the same place on the seat.
  • European patent EP-A-549 026 describes a chair comprising a mechanism which can also be described as global, but very simple for control at will the height of the seat and the inclination of the backrest, this mechanism comprising an operating lever which can take different positions in which, by a set of articulations, it confers different configurations on the elements of the seat, somewhat like a gearbox control lever. Strictly speaking, this is therefore not a question of controlling settings of a different nature.
  • the invention relates to an office chair comprising means for adjusting the various mobile and / or deformable elements with which it is equipped, whose individual controls of all of said adjusting means are grouped at the same point of the seat in a single multifunctional member or "command satellite", said commands being differentiated by the type of movement to be performed on a determined element different from said satellite to actuate each command.
  • Such an arrangement has the considerable advantage of making the controls more intuitive, since they are located in the same place but clearly clearly differentiated in terms of movement to be carried out to actuate the control. Furthermore, thanks to the design of this satellite, these controls are easier - in particular for adjusting the tilting tension of the seat which is on the side of the seat and no longer under the seat as is usually the case. the case - and more aesthetic, since several levers and levers are replaced by a single "control satellite".
  • the height of the seat being adjustable in a known manner by a pneumatic system involving a jack, for example, a cartridge preferably with compressed gas capable of supplying two coaxial cylinders, the communication between these cylinders, with a view to their mutual sliding, being determined by the opening of a valve, said opening is controlled by traction on a cable, this traction itself resulting from the axial translation of an element carried by said satellite, the along said first tree.
  • a pneumatic system involving a jack, for example, a cartridge preferably with compressed gas capable of supplying two coaxial cylinders, the communication between these cylinders, with a view to their mutual sliding, being determined by the opening of a valve, said opening is controlled by traction on a cable, this traction itself resulting from the axial translation of an element carried by said satellite, the along said first tree.
  • the tilting tension of the seat being adjustable in a known manner by a system involving the variation of the torsion applied to at least one helical spring wound on the axis of said tilting, said variation results from the position, along a thread carried by said first axis, of a nut, under the effect of the rotation of said first axis, while the blocking of the backrest in any position of the backrest results from the action, on a portion of said backrest, of a rotary cam , the rotation of this cam resulting, via a linkage, from a rotation of said second shaft.
  • the office chair comprises in this embodiment, a multifunction satellite, in which, on a first shaft is mounted in translation a member controlling the traction of a cable determining the opening and closing of the valve of the height adjustment system of the seat relative to its base, on this same first shaft is mounted on a threaded portion a nut movable axially under the effect of the rotation of said first axis, this nut determining the variation in tension at least one torsion spring to which the seat is subjected in order to adjust the tilting tension of said seat, and finally around this same first shaft is mounted rotating a second shaft, the rotation of which determines the action of a member ensuring the locking of the backrest in any one of at least two predetermined positions, for example either in the vertical position or in the inclined position.
  • the above definition relates to a preferred embodiment of the invention, but many construction variants can be envisaged, the essential aim sought being the grouping in a single point, preferably located on the side of the seated, easy to reach by the user in the seated position, with all the controls for adjusting the various functions allowing the seat to be best adapted to the comfort of the user, whatever its size, shape or work he has to perform.
  • the same seat can be arranged so as to allow other functions to be fulfilled, such as for example the transverse distribution of the flexibility of the seat.
  • the lower portion of the casing containing the various adjustment and control mechanisms of an office chair is designated by 1 and which is fixedly mounted on the upper portion C of a support column, itself pivoting on the lower portion C ′ of the same column, which is fixed to the base proper (not shown), in a conventional manner.
  • the upper portion 2 of the same casing is pivotally mounted with respect to this portion 1 about an axis 3.
  • the portion 1 is associated with the seat (not shown), while the portion 2 is associated with the backrest (not shown).
  • these three adjustments are controlled by three levers or levers distributed under the seat, acting individually and independently on the three mechanisms.
  • the height adjustment of the seat is controlled by action on the crown 8, so as to pull the sector 9, bringing it closer to the button 5.
  • a circular slot is made, crossed by the end of the cable 10, ending in a bead 13, which holds it in place. Thanks to this circular slot, this maneuver is possible whatever the angular position of the sector 9, which is necessary due to the second function of the crown 8, which is filled by rotation.
  • the cable 10, from sector 9, travels below the fixed portion 1 of the casing, inside which it penetrates through a hole 14 (FIG. 2) to hang on, for example by a bead 15, to the end of a trigger finger 16, resiliently held by a bearing, 17 on the trigger valve 18 of a compressed air cartridge associated with the seat height adjustment system, the principle of which was recalled above.
  • the elastic bearing 17 normally maintains the valve 18 in the closed state, ie blocks the system at any chosen height, while exerting a restoring force on the cable 10.
  • connection rod 11 hooked at one end to the sector 9 is for this purpose hooked at its other end to a connecting rod 19 fixed in rotation with an axis 20 carrying cams 21 made of plastic, which, in at least one position, block by friction against the tilting portion 2, that is to say the backrest, at a given inclination, while, in another position, they release said backrest.
  • cams 21 made of plastic, which, in at least one position, block by friction against the tilting portion 2, that is to say the backrest, at a given inclination, while, in another position, they release said backrest.
  • the flexibility of the operation is ensured for example by a leaf spring 22 pressing on the cam 21.
  • Flexible stops such as 23 avoid too abrupt stopping of the backrest in the released position.
  • Such an inclination adjustment can be designed in many forms, for example blocking the backrest in the advanced position, multi-position blocking, a tilting limitation or any other function relating to the inclination of a backrest.
  • the invention naturally includes the control of all these variants, such as that illustrated in FIG. 6 which will be described below.
  • Button 5 also allows the control of a third functionality, namely the adjustment of the seat tilting tension.
  • the axis 4 which can rotate freely inside the axis 7, enters the interior of the portion 1 of the casing, where it ends in a threaded portion 6.
  • a nut 24 ( Figures 1 and 4a) which, via a stud 25 drives an arm 26 pivotally mounted on an oblique axis 27 ( Figure 4b).
  • This arm 26 cooperates with a plate 28 to which are fixed the ends of a couple of torsion springs 29, 29 'wound around the axis 3 of tilting of the portion 2 carrying the backrest.
  • the nut 24, fixed in rotation moves axially, in one or the other direction, driving by the pin 25, the arm 26 in pivoting around the oblique axis 27. Because of this obliquity, the plate 28 will take a tilting movement, by pressing more or less on the ends of the springs 29, 29 ', by modifying the torsion of the springs 29, 29', and consequently the tilting tension, i.e. the effort to be exerted by the user to tilt the backrest.
  • FIG. 5 illustrates a variant of the mechanism for locking the inclination of the backrest.
  • the crown 8 the axis 7, the sector 9 and the connecting rod 11 but the link 19 'is located in a plane perpendicular to that in which the link 19 operated, so as to provide better transmission from the action of the rod 11 to a part 21 ', which plays the role as the part 21, but no longer offering two extreme locking positions, but four, thanks to four ribs 30 which can be brought into play according to the angle of rotation of the crown 8.
  • a spring 31 relieves "the part 21 'at each change of rib.
  • the satellite is shown here located laterally with respect to the seat: it could as well be located at any other point, for practical and / or aesthetic reasons.
  • This satellite combines the commands of three particular settings: it could as well group a different number of equally different settings, depending on the needs of the user. It is therefore understood that the invention can only be limited by the scope of the claims below.
