Definitions

  • the present invention relates to an active dynamic chair according to claim 1.
  • the invention relates in particular to an active dynamic seating device with a seat part for commuting and moving from a rest position to a deflected position, wherein also movement forms of a combination and / or superimposition of elliptical movements and pendulum movements can be executed.
  • 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 seated on the chair can perform movements of the trunk and the body together with the seat part, which is not possible with static chairs.
  • 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 active dynamic pendulum chair is known for example from DE 42 44 657 02.
  • a generic seat device which consists of a foot part, an intermediate part connected to the foot part and a seat part rigidly connected to the intermediate piece, wherein the intermediate piece is held tiltable in each side direction by means of an elastically deformable connecting element in an opening of the foot part and is returned to its neutral position (rest position) in the unloaded state.
  • EP 0 808 1 16 B1 a pendulum bearing is described, which is arranged between the column and the foot part.
  • 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.
  • US 5921926 shows an active-dynamic pendulum chair, which is also based on the principle of an inverted pendulum. Such chairs have a defined path of movement and a structural return mechanism, which at the same time have a protective device to prevent the chair from tipping over. However, the seat tilts during a pendulum movement to the rearward of the horizontal position in a direction away from the body center inclined position.
  • 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 moved from its rest position to any desired angle, steers, so the seat inclines 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 the 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.
  • horizontal translational movements of the seating area should also be Ches are made possible by the chair user and the change of the seat tilt according to the ergonomic needs of the seat user done.
  • German Patent Application No. DE102013102034.8 is incorporated by reference into the present application.
  • 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 comprising at least three legs with foot parts is provided at its lower end, wherein the legs are each movable at their upper end on seat part-side connecting joints on the seat part. are stored, so that pendulum and circular movements (and preferably also torsional movements) of the seat part with respect to its non-deflected rest position are executable.
  • 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 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 can take place either by means of several movable chair legs, in particular pendulum legs (hereafter referred to as legs) on the seat part in this embodiment, at its (upper) connecting ends not rigid, but by means of a movable (preferably elastic) connecting joint movably connected to the seat part, so that spatial pendulum and circular movements and preferably also torsional movements of each associated leg opposite the seat part are possible.
  • three or four legs are each connected to the seat part of the chair with identical or identical connecting joints. But it can also be used more than four legs.
  • the spatial (yielding) 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 comprising at least three legs with foot parts at the bottom thereof 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 is defined by the two offset by the azimuth angle of 90 ° polar angle ( ⁇ - ⁇ , ⁇ 2 ) of the normal on the previously explained seat part level. 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.
  • movements can be executed by a polar angle ⁇ at different azimuth angles ⁇ with respect to the seat part plane.
  • Each two pairs of legs can then be considered via the coupling with the seat as a four-bar linkage, wherein the feet of the legs are supported at defined points on the ground. It is preferred if each of the connecting joints is designed as such a joint, which allows a pendulum and circular motion of the leg connected to the respective connecting joint with respect to the seat part plane and ygc such that the seat part can be deflected into a plurality of different positions can be described by a bevy of motion curves.
  • the inclination of the seat part plane of the seat part changes during movement of the seat part from the rest position into a deflected position such that the area of the seat which is in each case further out when movements are carried out is raised relative to the area lying further inside or lowered.
  • 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 which "positions itself" when 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
  • an articulated quadrilateral of two legs is formed with the seat part and the bottom surface, whose coupling (seat part) is shorter than the frame (bottom surface)
  • the distance between their upper connecting ends in The foot parts may also be connected on a common foot plate or a common ring element by means of connecting joints, the degrees of freedom of movement of which are identical to the connection joints on the seat part is an embodiment in which 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 stand directly on the bottom surface, where they are optionally additionally provided with a non-slip end piece (to prevent slippage) or the like.
  • a movement sequence 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 remains 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.
  • the "flexible" joint system can also be realized by means of elastic legs.
