Definitions

  • the patent US2002158492A1 proposes a torso support at the front and the patent WO2007115418 proposes a torso support in combination with a back support.
  • the adaptation of those supports is fixed to one position and that for any different position an adaptation is needed, also the support at the heigth of the breast is hindering the freedom of movement of the user. This is especially a problem where complex and precision work is needed in the treatment such as for example is the case at dental surgery or dentists.
  • This aim is being reached by providing the work chair in combination with a tilting construction for the forward tilting of the seating part together with a support construction, to support the front side of the ilium in a limited forward bended seating position.
  • a support construction to support the front side of the ilium in a limited forward bended seating position.
  • the weight of the body is partly carried by the front of the ilium and the legs are deloaded significantly.
  • the ilium is forced into a fixed position, which decreases uncontrolled torsal movements of the two parts of the ilium and more support is offered for the movement from out of the spinal column.
  • Such a support device can for instance exist of a support surface that is placed in a fixed position in relation to the seating surface, that supports the ilium at the front side whilest bending forward.
  • a further version of the invention provides in a support device for support of the ilium in which the ilium of the one seated is clamped by a configuration of a for this purpose fixed and in relation to each other adjustable seating part, a front support and a back support.
  • the invention makes use of a spring device with an adjustable force in relation to the weight of the user, that is working against the tilting movement of the seating part and by doing so is working against the whole configuration. The user can hereby bend forward against the spring force and supported by the configuration, through which the legs are disloaded proportionally.
  • the invention makes use of a position of the tilting point around an axis behind the centre of gravity, so that a decreased pressure on the legs can easily start the tilting movement around this axis without any further effort.
  • This enables a dynamic seating posture, in which every seating position between being bended forward and sitting upright can be reached by relocating the feet or by lowering or increasing the tension of the leg muslcles thus changing the counter pressure, which enables the configuration to tilt upto an aimed position and than again slightly changing the counter pressure to remain the balance or to slightly increase the counter pressure by using the leg muscles until the next aimed position is reached and then changing the counter pressure again to remain in balance.
  • the support device of the ilium is existing of a configuration of seating part (22) that is supporting the seating bones and a back part (21) that is supporting the back part (A) of the ilium and two both anatomically to the body shaped cushion supports (19 and 19') to support the two front parts (V) of the ilium, for the aim of which those cushions (19 and 19') are mounted to an arm (20) respectively (20') that is mounted to or near a side of the chair under or beneath the seating part and that can be turned away sideways by a hinge that is mounted more or less parallel to the seating direction in such a way that every arm (20 and 20') can also be adapted in an axial direction and thus can be fastened in both directions without any steps.
  • the cushion supports (19 and 19') can be mounted turnable in an axial way in or around the arms (20 and 20'), so that the corner adjustment of the cushions is self-seeking.
  • a column On a star foot (1) with wheels a column is mounted (2) in which a second in height adjustable column (3) is mounted conform the known technical solutions used by office chairs.
  • a horizontal profiled plate (4) is mounted, with at the back side of the column (3), parallel to the front and back side of the chair behind the centre of gravity of the seating position a combination of a horizontal rotation and torsion axis (5) is mounted and around which a assembly of profiled mounting panels (4) and (6) for the tilting movement of the configuration of the seating part and other ilium supports limitedly rotable is hung up with the counter pressure of the torsion axis (5) connected to a lever (9) provided with a adjustment bolt (18) for varying the pressure.
  • the assembly of mounting panels (4) and (6) and the components mounted to those, existing of support arms (20), back support (21) and seating part (22), enables adjustification of diverse positions of diverse components because the profiled mounting plate (4) that is mounted turnable to the column is provided on both sides with a crossed to the torsion- and rotation axis (5) standing axis (11) that is mounted between vertical flanges (12) and along which the second mounting panel (6) can move axial by use of bearing cilinders that are positioned between folded flanges (6') and to which support arm (20)(20') for the ilium support (19) (19') by use of a bearing cilinder (23) is mounted axial movable along the axis (11), whereby the support arm (20) can also rotate freely around this axis (11).
  • both arms (20 and 20') are being pushed away sideways, one to the left and one to the right thus enabling the one seated to stand up unhindered.
  • the axial movement can be blocked by a lever (24) that is hooking into the holes in the mounting panel (4) or for example in a technical known clamping device that grips around the bearing axis (11) and is mounted to the mounting plate (6) with which the arm is connected.
  • the invention forsees in a seat that also supports a part of the upper legs with the characteristic that after the part to which the ilium is leaning, the seat can bend back, against a light spring pressure and that in the posture of sitting upright the seat is being pushed down by the legs in such a way that in the posture of being bended forward the legs are noticably slightly supported.
