Definitions

  • the present invention relates to a chair, especially an office chair, with a stand resting on the floor, on which a seat face is arranged, the inclination of the seat face being adjustable in relation to the stand.
  • the publication DE 10 2010 042 913 discloses a chair, wherein a seat carrier is supported on a foot stand. A seat is pivoted in the seat support, the inclination of the seat being adjustable. In order to adjust the inclination an extensive mechanism is provided having adjustment elements and a toothing. The assembly of this adjustment mechanism is comparatively extensive and further there is a risk for the mechanical elements to become restrained.
  • the object of the present invention is to provide a chair, in which with ordinary means an adjustment of the inclination of the seat face is obtained.
  • the pneumatic or hydraulic means comprises at least one cushion which can be filled with a fluid.
  • the cushion can support the seat face, so that by inflating the cushion the seat face will be adjusted in relation to the stand of the chair.
  • the cushion can for example be designed as a pleated bellows, which when inflated expands essentially in the vertical direction, and when deflated decreases correspondingly.
  • at least one valve is provided, with which the fluid pressure in the cushion can be adjusted.
  • the valve can in particular be manually controlled through an actuator in order to reduce the pressure in the cushion, whereby the valve optionally is in direct communication with the cushion itself or in communication with the cushion via a conduit.
  • the valve is accessible at the underside of the seat face for a person sitting thereon.
  • a pump is provided, with which the cushion can be filled with fluid.
  • the pump can be manually actuated in order to be able to perform an adjustment of the seat face independent from a driving means.
  • the pump can for example be designed as a bellows with which through a corresponding valve control said at least one cushion can be inflated, and optionally also a discharge of the fluid through the pump can be undertaken.
  • the chair preferably has a seat plate, on the upper surface of which being the seat face, and which is pivotally supported in a bearing.
  • the seat plate can be supported on a bracket or support on the stand, and said at least one cushion, which can be inflated with a fluid, can be provided between the seat plate and the bracket.
  • the bearing can be designed as a pivot bearing or as a bridge bearing.
  • the cushion is preferably formed as a hose and extends in longitudinal direction over at least 50 %, esp. at least 70 %, of the width of the seat face. It is also possible to, instead of having only one cushion, provide two or several cushions, which are mutually connected through a hose. Thereby the volume to be inflated is reduced, which facilitates and accelerates the adjustment procedure.
  • the seat face can be adjusted in an interval between 0 and 20°, in particular 5° to 15°, preferably at least about 10°, depending on the specific application.
  • the seat and partly also a support underneath the seat are coated with fabric or leather, while a more elastic material can be arranged on the side surfaces in relation on the seat face.
  • the pneumatic or hydraulic means, in particular the seat cushion can be arranged to be covered by the coating, whereby during an inclination adjustment the increase or decrease of a distance between the seat face and a bracket or a support will be covered by the elastic material on the side surfaces.
  • the seat plate might have a rigid lower part, in particular a plate formed lower part, and un upper part consisting of an elastic foam.
  • a chair 1, illustrated as a swivel office chair, comprises a stand 2, which has a foot part 3 with several rolls 4 which can be supported by the floor.
  • a carrier 5 is height adjustably held by the foot element 4, a bracket 6 being arranged underneath the seat face 10.
  • the chair 1 comprises a back rest 8 held on a support 7, on which the arm rests 9 are provided.
  • the back rest 8 and the arm rests 9 can be adjustable via known adjustment mechanisms.
  • the bracket 6 may comprise a seat depth adjustment in order to be able to adjust the horizontal extension of the seat face 10 in relation to the back rest 8.
  • the seat face 10 is formed by an upper surface of the seat plate 11, the inclination of which is adjusted.
  • pneumatic or hydraulic adjustable means are provided in the form of at least one cushion 12, which is arranged between the seat plate 11 and the bracket 6.
  • the seat face 10 is arranged essentially horizontal.
  • the cushion 12 which can be filled with fluid, is inflated and will then force the back part of the seat plate 11 upwards, while the seat plate 11 at its underside is supported in a bearing 13 on the bracket 6.
  • This bearing 13 can be designed as a pivot bearing or as a bridge bearing, so that the seat plate 11 pivots in this bearing 13.
  • the seat plate 11 can be configured in several parts and for example it might comprise a form-stable plate-like lower part and an upper part made from foam, so that the seat plate 11 can be pivoted as a single unit by the cushion 12.
  • the seat plate 11 may be coated with a cover of fabric, which on the side surfaces at least in certain areas may be a more elastic material compared to on the upper side of the seat face 10. Thereby, a compensation through the fabric cover takes place when the seat plate 11 is pivoted.
  • the seat plate 11 is essentially horizontal, while in Fig. 3B the seat plate 11 has been pivoted over an angle ⁇ of for example 5°, which is accomplished by inflating the cushion 12 which can be filled with a fluid.
  • the cushion 12 can thereby be designed as a hose and might extend over more than 70 % of the width of the seat face.
  • the cushion 12 may have a cover made from an elastic material, in particular a gum, plastic or silicone.
  • a pneumatic or hydraulic adjustment mechanism is shown in Fig. 4 , in which two cushions are used, being mutually connected via a hose 18.
  • a first cushion 12 is thereby connected to a pump 15 via a conduit 14, which is designed as a manual pump, e.g. a bellows, which is arranged within the area of the bracket 6 underneath the seat face 10.
  • the second cushion 12 is connected with a valve 17 via a conduit 16, with which the pressure in the two cushions 12 can be reduced, for example by pressing by hand a corresponding discharge button.
  • the valve 17 may be arranged in the area of the bracket 6 underneath the seat face 10 as well. It is also possible to provide the pump 15 and valve 17 adjacent to each other, or to provide the pump 15 with a corresponding valve 17.
  • the cushions 12 are preferably inflated with surrounding air, since this can be drawn into the pump 15 without any problems.
  • FIGs. 5A and 5B a further embodiment of the chair according to the invention, wherein the like parts have been provided with the same reference numbers as in the previous Figs.
  • the chair comprises a stand 2 with a foot element 3, which is supported on rolls 4 on the side facing the floor.
  • a support 5 is held at the stand 2, on the upper side of which a seat plate 11 with a seat face 10 is arranged.
  • two cushions 12' are arranged underneath the seat plate 11, which cushions are formed as bellows, and they are extended/retracted substantially in the vertical direction when inflated/deflated with a fluid. Thereby the seat plate 11 can be pivoted.
  • the seat plate 11 is thereby mounted on a pivotable plate 20, which has an angled protrusion 21, which is pivoted in a retension or a bearing 22 at the support 5.
  • a pneumatic means for the adjustment of the seat plate 11 which comprises two cushions 12', being inflatable through a pump 15'.
  • the pneumatic means is thereby arranged on a shell formed retension 23 of the support 5.
  • a valve 17' for discharge of air from the cushions 12'.
  • the seat plate 11 is covered with a covering, which has a flexible material 24 at the side areas, which material is stretchable and thus can cover the side areas also during inclination adjustment of the seat plate 11. The covering is thereby fastened so that it surrounds the support.
  • the chair is shown without seat plate 11, illustrating that the two cushions 12' are mutually connected through a hose 18' and that a conduit 14' opens in the hose 18'.
  • the conduit 14' will be supplied with a fluid through the pump 15', in particular ambient air.
  • the cushions 12' By constructing the cushions 12' as bellows an adjustment can be obtained with a smaller air volume, since the bellows are not stretched uniformly in all directions, but instead an extension takes place essentially only in a vertical direction. With the bellows annular wall parts can be folded in meander form onto each other, when the air is discharged from the bellows. Instead of the circular cushions 12', cushions having other designs can be used as bellows.
