Definitions

  • the invention relates to an active dynamic seat device the features of the preamble of claim 1.
  • seat devices have been developed that a enable so-called active dynamic sitting, in which the Back muscles and intervertebral discs always in action are.
  • This active dynamic sitting posture becomes practical achieved in all cases that the actual seat of the Seat device is held in an unstable position and possibly additionally springs in the vertical direction.
  • Such an active dynamic seating device is for example described in DE 73 11 140.
  • This seat device consists essentially of a seat part, which over a first tilt joint is connected to a support shaft, which in turn by means of a second tilt joint on Foot part of the seat device is articulated.

Disadvantageous the fact that the suspension is relative by a gas pressure spring is expensive.
  • the invention is therefore based on the object of an active dynamic To create a seat device, the one hand Sufficiently active sitting position guaranteed and on the other hand, the safe use of the seat device even without a longer training phase or getting used to it and moreover without a gas pressure spring.
  • the firm connection of the seat part of the invention Seat device with the intermediate piece and in every direction deflectable connection of the intermediate piece with the foot part on the one hand ensures active dynamic sitting.
  • by using a single tilt joint in connection with a device for resetting the intermediate piece and the seat part in the neutral Location ensures that the seat device is also practical inexperienced people without long acclimatization period can be because the balance of the invention Seat device is not as unstable as high in previously known active dynamic seat devices.
  • This reset device can, for example, as a at the same time serving as a rocker joint or as additional spring elements acting on the intermediate piece be trained.

  • To promote the seat cushion 10 can have an anatomically favorable sitting position be convex, concave, flat or wedge-shaped. At a wedge-shaped formation should be the higher end of the wedge in the back of the seated person.
  • the seat cushion in a preferred embodiment have a dimensionally stable core in order to improve the shape of the seating posture desired, even under load maintain.
  • Coil spring 11 arranged, which with its upper end Plate 9 of the seat part 3 or a horizontally in the upper hollow cylinder 8 arranged intermediate floor acted upon and with its lower end on the flexible element 6 or one in lower hollow cylinder 7 horizontally arranged intermediate floor lies on.
  • the seat height can be easily inserted of spacers 15 between the flexible element 6 and the washer 13 are changed.
  • the spacers 15 by means of a no closer shown holding device releasably with the flexible element 6 or the lower hollow cylinder 7 connected.
  • the upper hollow cylinder 8 at least one in vertical Direction elongated hole in which an am engages lower hollow cylinder 7 arranged pin or pin.
  • the upper or lower stop can be used for the vertical movement of the seat part 3 or the upper hollow cylinder 8 by appropriate training of the elongated hole as well as by a suitable positioning of the pin relative to the slot.
  • the foot part 1 can also be any other Take shape, which is the stability of the seat device guaranteed and the maximum tilt angle of the intermediate piece 2 limited in the manner described above.
  • the foot part can be arranged in a star shape Have feet that are pulled up to the intermediate piece and at its upper end with one that limits the tilting movement Frames are connected.
  • rollers can be arranged to easily move the seat device to enable.
  • the foot part 1 can easily which have a convexly curved bearing surface, which likewise the displacement of the seat device by the smaller one Support surface made easier. It has also been shown that such a very slight curvature of the contact surface - with a diameter of the foot part of approx. 50 cm - 60 cm should the edge area of the foot part a distance of approx. 0.5 cm - 1 cm from a flat support surface - positive for that desired seating behavior affects.
  • Fig. 2 shows a further embodiment of the embodiment 1, in the additional devices 16 for Provision of the unloaded intermediate piece 2 or the unloaded Seat part 3 are provided in the neutral position.
  • These reset devices 16 consist of the circumference of the lower hollow cylinder 7 attached flexible tension elements 17, which through corresponding openings in the inner wall of the base part 4 are guided into the interior of the base part.
  • the tension elements are created by means of deflection elements 18 which e.g. are designed as roles, so redirected, that they are essentially parallel to the inner or outer wall of the base part.
  • the ends of the tension elements 17th are each also arranged in the interior of the base part 4
  • Coil springs 19 connected.
  • the coil springs 19 are preferably also in the neutral position of the intermediate piece 2 biased.
  • the reset devices 16 can of course also be used in formed in a different way and not inside the base part 4 be arranged.
  • FIG. 3 corresponds essentially in its function to the embodiment 1.
  • foot part 1 consists of a Base part 20, which has several - preferably five - feet, to ensure the stability of the seat device and an outer hollow cylinder 21, which is the intermediate piece 2 surrounds.

  • the coil springs 22 are in the radial direction between the lower Hollow cylinder 7 and the outer hollow cylinder 21 of the base part 20 arranged and by means of not shown holding or fasteners connected to them.
  • the coil springs 22 can act as compression or tension springs and ensure that the spring constant is selected accordingly on the one hand, the provision of the unloaded intermediate piece or seat part in the neutral position.
  • the tilting movement of the intermediate piece is caused by the Coil springs 22 limited to a maximum allowable angle.
  • the dimensioning of the coil springs 22 and possibly by dimensioning the flexible element 6, i.e. by dimensioning the reset devices also the characteristic of the unstable balance of the seat part 3 and thus the characteristics of the active dynamic sitting position fixed.
  • the reset also take place through a rubber membrane designed as a circular ring, the outer hollow cylinder 21 and the lower hollow cylinder 7 connects.
  • the embodiment of the invention shown in Fig. 4 has an intermediate piece 2, the upper region of which is essentially with the intermediate pieces of those described above Embodiments is identical. Because in this by the two Hollow cylinder formed area of the upper intermediate piece neither Reset devices attack another stop provided is, the lower hollow cylinder 7 can also within the upper Hollow cylinder 8 are performed.
  • the intermediate piece 2 In its lower, adjoining the lower hollow cylinder 7 Area, the intermediate piece 2 has a bearing part 30, which has the shape of a spherical body, i.e. the shape of a top and ball cut off in horizontal planes below.
  • the diameter of the ball is preferably chosen to be larger than the outer diameter of the lower hollow cylinder 7.
  • the bearing part 30 On its underside, the bearing part 30 is cylindrical Part 31 connected, preferably on the underside circular plate 32 is arranged.
