Definitions

  • the present invention relates to an active dynamic chair according to claim 1.
  • the invention particularly relates to an active dynamic seating device with a seat part for swinging and moving from a rest position to a deflected position, wherein also movement forms of a combination and / or superposition of elliptical movements and pendulum movements are performed can.
  • the relative change in inclination of the seat part is influenced by the specific formation of a spatial joint system.
  • Movable or active-dynamic chairs differ from static chairs in that the chair user sitting on the chair can thereby perform movements of the trunk and the body together with the seat part, which is not possible with static chairs.
  • Seating furniture is equipped in most cases with appropriately designed seating surfaces and backrests in an anatomically most favorable position, so that the body, in particular the back, is supported.
  • Such seating furniture is often perceived as comfortable, but has the significant disadvantage that the body is only passive, i. E. the back muscles are hardly stressed and the discs experience a permanent pressure load. With prolonged use of these seating devices, this can lead to degeneration of the back muscles and wear of the intervertebral discs. Health damage and pain in the back and hip area are a frequent consequence of static or passive sitting.
  • active-dynamic seating devices have been developed that allow for so-called active dynamic sitting in which the back muscles and discs are always in easy action.
  • This active dynamic sitting position is achieved in virtually all cases in that the actual seat of the seat device is held in an unstable position and can be reciprocated by the seat occupant from a rest position to a laterally deflected position.
  • Such an active dynamic pendulum chair is for example from the DE 42 44 657 02 known.
  • a generic seat device which consists of a foot part, an intermediate piece connected to the foot part and a rigidly connected to the spacer seat part, wherein the intermediate piece is held by means of an elastically deformable connecting element in an opening of the foot part in each lateral direction tilted and in unloaded state is returned to its neutral position (rest position).
  • the pendulum bearing is designed as a vibrating metal and consists of a substantially tubular upper part, the upper end of which serves for the spline connection, a lower part which is fixedly secured to an arm of the foot part and an upper part and lower part arranged elastic material.
  • the self-aligning bearing allows a swinging of the seat part.
  • Such pendulum chairs allow the back and forth of the seat from the non-deflected starting position in different deflected positions, whereby the seat tilts from its horizontal position in an inclined inclination.
  • the tilt angle depends on the direction of the deflection and the degree of deflection.
  • the seat tilts in a pendulum chair in which the horizontally mounted seat is firmly connected to a reciprocating pendulum column, with increasing deflection of the column from its horizontal position to a significant angle.
  • the degree of inclination of the seat follows exclusively as a function of the deflection angle during the pendulum movement.
  • the seat In the rest position, the seat usually has no inclination, but the (idealized) seat is aligned parallel to the floor surface. If the seat is now deflected from its rest position into any inclined position, so the seat tilts accordingly, since the seat is rigidly connected to the pendulum support. The greater the angle of the pendulum movement, the stronger the inclination of the seat. In this case, the seat tilts when moving back and forth from its rest position to its deflected position, so that when moving in relation to the rest position each further outward area of the seat is lowered relative to the more inward area.
  • the seat occupant comes in a supine position with pendulum movements backwards, which is not pleasant for every seat occupant. If the pendulum movements are too large, it could also happen that the seat occupant loses his balance.
  • pendulum chairs with different, preferably adjustable inclination change.
  • the present invention therefore has the object to overcome the aforementioned disadvantages and to provide an active dynamic chair, in which the seat user can perform safe and varied movements of the seat part throughout the movement space.
  • the seat user can perform safe and varied movements of the seat part throughout the movement space.
  • it should also horizontal translational movements of the seating area be made possible by the chair user and the change of the seat tilt according to the ergonomic needs of the seat occupant done.
  • the basic idea of the present invention lies in the suitable attachment and arrangement of a spatial (flexible) joint system, preferably formed from articulated quadrilateral corners.
  • a spatial joint system of at least three legs is provided with foot parts at its lower end, wherein the legs each mounted at its upper end to seat part side connecting joints on the seat part movable are such that pendulum and circular movements (and preferably also torsional movements) of the seat part with respect to its non-deflected rest position are executable.
  • At least three four-bar linkages are formed, wherein each four-bar linkage of two immediately adjacent legs, the seat part and the bottom surface is formed and its "coupling length" by the distance between the legs on the seat part and the frame length by the distance of the legs the floor surface is defined.
  • the realization of the joint systems can therefore be described equivalently according to the principle of the four-bar linkages.
  • the realization of the spatial joint system either by means of several movable chair legs, especially pendulum legs (hereinafter referred to briefly: legs) take place on the seat part.
  • the legs are in this embodiment at their (upper) connecting ends not rigid, but movably connected by means of a movable (preferably elastic) connecting joint with the seat part, so that spatial pendulum and circular movements and preferably also torsional movements of each leg connected to the seat part possible are.
  • a movable (preferably elastic) connecting joint with the seat part, so that spatial pendulum and circular movements and preferably also torsional movements of each leg connected to the seat part possible are.
  • three or four legs are each connected to the seat part of the chair with the same or similar connection joints. But it can also be used more than four legs.
  • the spatial (flexible) joint system can also be realized by means of flexible, elastically deformable legs, which are fastened to rigid fastening elements on the seat part.
  • an actively dynamic chair in its most general form, comprising: a seat part and a spatial articulation system of at least three legs with foot parts on its lower part End, wherein the legs are each movably mounted at its upper end to the seat part side connecting joints on the seat part, such that pendulum and circular movements of the seat part with respect to its non-deflected rest position are executable.
  • the positions of the connecting joints span a common seat part plane, whereby the relative inclination of the seat part can be defined.
  • the legs are arranged symmetrically and the relative inclination of the seat part extends in a parallel plane to the floor surface (on which the chair stands).
  • the relative inclination of the seat surface is defined by the two polar angles ( ⁇ 1 , ⁇ 2 ) of the normal offset by the azimuth angle of 90 ° on the seat part plane explained above. If the seat part plane is oriented parallel to the floor surface, both angles are 0 °.
  • the active-dynamic chair is designed such that each of the connecting joints is designed as a joint, which enables pendulum and circular movements of the leg connected thereto. In other words, movements can be executed by a polar angle ⁇ at different azimuth angles ⁇ with respect to the seat part plane.
  • each of the connecting joints is designed as such a joint, which allows a pendulum and circular movement of the connected to the respective connecting joint leg relative to the seat part plane and preferably such that the seat part can be deflected in a variety of different positions that through describe a bevy of movement curves.
  • the inclination of the seat part plane of the seat part changes with movements of the seat part from the rest position into a deflected position such that the area of the seat lying further out when movements are carried out is raised or lowered relative to the area lying further inside becomes.
  • the inclination change of the seat can be adjusted by the leg length of the legs and their relative orientation is formed accordingly.
  • a sequence of movements with a seat part plane "erecting" when it is deflected backwards can be realized by, for example, the legs not being aligned parallel to one another, but the foot points of two legs being further spaced from one another, compared to the upper connection points at the joints.
  • a four-bar linkage is formed from two legs with the seat part and the bottom surface, the coupling (seat part) is shorter than the frame (bottom surface). It is preferred that in each case adjacent legs, the distance between their upper connecting ends in the seat part level is less than the ground-level distance of the respective leg ends between their foot parts.
  • the foot parts can also be connected on a common foot plate or a common ring element by means of connecting joints whose movement degrees of freedom are identical to the connecting joints on the seat part.
  • a common foot plate or a common ring element by means of connecting joints whose movement degrees of freedom are identical to the connecting joints on the seat part.
  • the inclination of the legs on the base plate and / or on the seat part is changeable. This can be done by providing position adjustable joints.
  • the foot parts can also be directly on the bottom surface in an alternative embodiment, where they are optionally additionally equipped with a non-slip end piece (to prevent slipping) or the like.
  • a parallel preferably vertical alignment of equal legs also a movement can be achieved, in which the inclination of the seat part level does not change when moving the seat part, but the seat part plane is aligned parallel to the bottom surface and only lowered.
  • a symmetrical four-bar linkage of two legs each with the seat part and the bottom surface is formed.
  • a well-known from the transmission gearing four-bar linkage usually consists of a coupling, a frame and two links. That is, transferred to the articulated spatial quadrilaterals according to the present invention, the seat part of the chair can be regarded as a "paddock" and the floor surface as a "frame", while the legs are to be considered as connecting links.
  • the joint system is further equipped with a resilient return mechanism, so that the deflected seat part is automatically returned to its rest position.
  • the return mechanism is integrated in the connecting joints. It is therefore particularly advantageous to form the joints as elastic (elastically deformable) joints, which generate a restoring force during a deflection, when the chair leg is guided from its rest position into a deflected position.
  • the joints can be formed as elastic rubber joints, which are elastically deformed when moving the legs and thus generate a restoring force.
