Definitions

  • the invention relates to an active dynamic seating device with the features of the preamble of patent claim 1.
  • conventional seating is designed in such a way that the body, in particular the back, is supported in an anatomically favorable position by appropriately designed seats and backrests.
  • seating is often perceived as comfortable, it has the decisive disadvantage that the body only sits passively on such seating, i.e. the back muscles are hardly stressed and the intervertebral discs are only subjected to static "pressure".
  • the prolonged use of such seat devices leads to degeneration of the back muscles and to wear of the intervertebral discs.
  • Health damage and pain in the back and hip area e.g. sciatica are the frequent consequence of such static and passive sitting.
  • seat devices have been developed that enable so-called active dynamic sitting, in which the back muscles and the intervertebral discs are always slightly in action.
  • This active dynamic sitting posture is achieved in practically all cases in that the actual seat of the seat device is held in an unstable position and, if necessary, also springs in the vertical direction.
  • This seat device consists essentially of a seat part, which has a the first tilt joint is connected to a support shaft, which in turn is articulated on the foot part of the seat device by means of a second tilt joint.
  • Each tilt joint preferably consists of a spherical cap formed at the end of the support shaft, which is guided in a hollow cylinder and is acted upon by a helical spring arranged in the hollow cylinder.
  • the object of the invention is therefore to create an active dynamic seating device which on the one hand ensures a sufficiently active sitting position and on the other hand
  • SPARE2BLADE allows the safe use of the seat device even without a long training phase or getting used to.
  • the invention has for its object to provide an active dynamic seating device that is simple and inexpensive to manufacture.
  • the foot section ensures active dynamic sitting.
  • the use of a single tilt joint in connection with a device for returning the intermediate piece and the seat part to the neutral position ensures that the seat device can also be used by practically inexperienced persons without a long period of familiarization, since the balance of the seat device according to the invention is not unstable to a high degree, as in previously known active dynamic seat devices.
  • Tilt joint designed as a ball bearing or double cardan bearing.
  • the resetting device is designed as an elastic membrane which is used for
  • ERS A TZBLATT one is connected to the intermediate piece below the bearing point and the other to the foot part. Moreover, this membrane can behavior have recesses for setting a desired elasticity ⁇ .
  • the restoring devices can be pretensioned, a stop being provided for the vertical upward movement of the intermediate piece at the same time.
  • FIG. 1 shows a first exemplary embodiment of the device according to the invention
  • Fig. 2 shows a second embodiment of the seat device according to the invention.
  • 25 seating device consists of a foot part 1, an intermediate piece 2 and a seat part 3rd
  • the foot part 1 consists essentially of a base part 4 in the form of a hollow cone section.
  • the base part 4 is double-walled and thus hollow on the inside.
  • the upper ends of the inner and outer walls of the hollow cone portion are a ⁇ lumps connected to a frame part. 5
  • a plurality of arms 6 extend radially inwards.
  • the intermediate piece 2 in its central, cylindrical region can be displaced in the vertical direction and can be tilted in the foot part 1 in any lateral direction.
  • the balls or rollers 7 are preferably resiliently mounted in the corresponding cages 8 in the radial direction.
  • the necessary spring travel for the balls or rollers 7 is, however, comparatively short, since the seat devices of this type have the
  • the cylindrical intermediate piece 2 is firmly connected to a plate 9 of the seat part 3, for example of circular design, on which a seat cushion 10 is attached.
  • the seat cushion 10 can for example be made of
  • the seat cushion 10 can be convex, concave, flat or wedge-shaped. With a wedge
  • the higher end of the wedge should be in the back of the seated person.
  • the seat cushion can have a dimensionally stable core in order to improve it
  • REPLACEMENT LEAF gen 11 consist stigten BEFE from the periphery of the intermediate piece 2 ⁇ flexible pulling elements 12 which are guided through corresponding openings in the inner wall of the base part 4 in the interior of the base part.
  • the tension elements are deflected by means of deflection elements 12 13, which are formed as a play roles in ⁇ so that they extend substantially parallel to the inner or outer wall of the Ba ⁇ sisteils.
  • the ends of the tension elements 12 are each connected to coil springs 14 which are likewise arranged in the interior of the base part 4. The coil springs 14 are biased with the weight of the seat part 3 and the intermediate piece 2 even when the seat part 3 is not loaded.
  • the coil springs can be subjected to an additional preload in order to generate higher restoring forces both for the tilting movement and for the vertical movement of the intermediate piece 2.
  • the upward movement of the intermediate piece 2 must be limited in order to bfcw the desired pretension when the seat part 3 is not loaded. maintain the intermediate piece 2.
  • the at ⁇ is impact ring 15 displaceable and lockable on the intermediate piece 2 adapted to the adjustment of the prestressing of the restoring devices 11 to a predetermined value to he ⁇ possible.
  • the stop ring can have locking screws 16 which act directly on the intermediate piece 2 or be designed as a clamping ring with corresponding devices for releasing and clamping.
  • the base 1 also assume any other beechi ⁇ ge form, which ensures the stability of the Wegvorrich ⁇ processing and enables the storage of the intermediate piece 2 in the manner described above.
  • the foot part can have a plurality of feet arranged in a star shape, which are pulled up towards the intermediate piece and at the upper end of which the bearing for the intermediate piece 2 is formed.
  • rollers can be arranged on the foot part 1 in a known manner in order to make it easier to move the seat device.
  • the foot part 1 can have a slightly convex downward bearing surface, which also facilitates the displacement of the seat device due to the smaller contact surface.
  • the edge region of the foot part should be a distance of approximately 0.5 cm - 1 cm from a flat support surface exhibit - has a positive effect on the desired seating behavior.
  • the mode of operation of the exemplary embodiment of the invention shown in FIG. 2 essentially corresponds to that of the exemplary embodiment described above. However, there are differences: on the one hand in the design of the mounting of the intermediate piece 2 in the foot part 1 and on the other hand in the design of the reset devices 11.
  • the intermediate piece 2 is stored in the foot part 1 by means of a bearing part 20, which has the shape of a Kv ⁇ ⁇ al or one
  • Kugelrumpfes ie the shape of a top and bottom in horizontal len planes cut off sphere.
  • the diameter of the sphere is to be chosen greater than the diameter of the interim ⁇ rule piece 2.
  • the ball or the ball body has a bore, whose diameter substantially corresponds to the outer diameter of the intermediate piece 2, so that the bearing part 20 is pushed onto the intermediate piece 2 can be and is performed on this essentially without play. If the bearing part 20 has the shape of a spherical body, the bore is preferably to be arranged centrally with the axis of rotation of the bearing part.
  • the bearing part 20 interacts with a bearing part 21 which is held in a horizontal plane by the arms 6.
  • the bearing ring 21 can be formed in two parts and releasably connected to the arms 6.
  • the storage of the intermediate piece 2 in the foot part 1 can also take place by means of any other bearing which allows both the tilting movement and a vertical displacement of the intermediate piece 2, such as. B. by means of a double-cardanically mounted part in the foot part, which receives the intermediate piece 2 in a bore vertically displaceable.
  • the resetting device 11 consists of an essentially circular elastic membrane 22 which, on the one hand, is connected to the lower area of the intermediate piece 2 in the region of its center point and, on the other hand, by means of suitably designed elements Holding devices is held in the interior of the base part 4.
