Definitions
- the invention relates to an active-dynamic seat device with the features of the preamble of claims 1 and 7.
- Conventional seating furniture is in most cases designed in such a way that the body, in particular the back, is supported in an anatomically favorable position by appropriately designed seating surfaces and backrests.
- seating is often perceived as a T-equem, 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 which 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.
- Such an active dynamic seating device is described, for example, in DE 73 11 140. This seat device
- HE S ATZBL ⁇ TT consists essentially of a seat part which is connected via a first tilt joint 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 acted upon by a helical spring arranged in the hollow cylinder.
- the flat design of the underside of the spherical cap lies in the unloaded state on the bottom or on the cover of the hollow cylinder, so that the foot part can be properly aligned without load.
- Support shaft and seat is given.
- this seat device When this seat device is loaded, the two helical springs of the tilting joints are pressed together, the two calottes being pressed into the two hollow cylinders.
- the tilting movement of these two joints is achieved in that the bore in the cover of the lower or in the bottom of the upper hollow cylinder is slightly larger than the outer diameter of the support shaft.
- the object of the invention is therefore to create an active dynamic seating device which, on the one hand,
- REPLACEMENT LEAF sufficient active sitting position is guaranteed and on the other hand enables the safe use of the seat device even without a long training phase or getting used to it.
- the invention has for its object to provide an active dynamic seat device that is simple and inexpensive to manufacture.
- the special design of the intermediate piece as bogen ⁇ shaped in the vertical direction 'resilient member adjacent to the seating comfort and the active sitting position is further improved.
- the arcuate intermediate piece has a second arcuate part, which is arranged within the first arcuate part and whose lower arm is connected to the lower arm of the first arcuate part.
- This second arcuate part is designed in such a way that, at least in a certain area between the first and second arcuate parts, a gap that increases with increasing distance from the point of connection of the parts is formed, and that an essentially wedge-shaped part is formed in this gap is slidably arranged to set a desired spring hardness.
- the seat part is connected to the intermediate piece by means of several spring bands, which are arranged distributed over the circumference of the seat part and the intermediate piece.
- Fig. 1 shows a first embodiment of the seating device according to the invention
- Fig. 2 shows a second embodiment of the seating device according to the invention.
- the exemplary embodiment of the active-dynamic seat device according to the invention shown in FIG. 1 consists of a foot part 1, an intermediate piece 2 connected thereto and a seat part 3.
- the foot part 1 has, in a known manner, a plurality of feet arranged in a star shape, which are integrally connected at their inner ends.
- a first arc-shaped resilient part 4 of the intermediate piece 2 is connected to the central region of the foot part 1 formed in this way, which has an essentially U-shaped course.
- the arcuate part 4 can consist of an appropriately dimensioned steel or plastic spring band.
- T no restoring forces are generated, additional restoring devices acting on the cylindrical part 7 or on the underside of the plate 9 of the seat part 3 must be provided.
- These resetting devices can be designed, for example, as tension or compression springs acting in the bore 15 between the cylindrical part 7 and the inner wall of the bore 15.
- the intermediate piece 2 can be designed in any other way, but there must be a suspension in the vertical direction.
- the foot part 1 can also take any other shape that ensures the stability of the seat device.
- a plurality of rollers can be arranged on the foot part 1 in a known manner in order to enable the seat device to be moved easily.
- 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 to 1 cm from a flat surface
- contact surface - has a positive effect on the desired seating behavior.
- the exemplary embodiment of the invention shown in FIG. 2 also consists of a foot part 1, an intermediate piece 2 and a seat part 3.
- the U-shaped intermediate piece 2 is connected to the foot part 1 so as to be rotatable about a vertical axis.
- the upper leg of the part 4 has a bore 5 in its front region, the vertical axis of which passes through the center of the foot part 1.
- the bore 5 serves to receive a flexible membrane 6, for example a rubber membrane, which serves as a bearing for the seat part 3.
- the flexible membrane 6 has to be mounted in the bore 5 a widened edge portion 6a which is connected to the extension of the bore 5 mecanicwan ⁇ glued and / or fixed by means of not shown holding devices in the bore 5 - st -
- the central region of the flexible membrane 6 is designed as a hollow cylinder 6b which serves to receive a cylindrical part 7 arranged on the underside of the seat part.
- the cylindrical part 7, which is preferably pressed into the hollow cylinder 6b of the flexible membrane 6, has at its upper end an area 8 with an enlarged diameter, via which the cylindrical part 7 is connected to a preferably circular plate 9 of the seat part 3 is. .
- a seat cushion 10 is arranged on the top of the seat part 3.
- the seat cushion 10 can, for example, consist of foam material covered with fabric and, if necessary, be connected to the plate 12 in a fixed or detachable manner.
- the seat cushion 10 can be convex, concave, flat or wedge-shaped. With a wedge-shaped design, 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 essentially maintain the shape desired to improve the sitting posture, even under load.
- the seat part 3 of the seat device according to the invention can thus be tilted in any lateral direction by means of the flexible membrane 6 and is essentially rigidly supported in the vertical direction.
- the tilting movement is made possible in particular by the annular region 6c of the flexible membrane 6.
- suspension takes place through the first arcuate part 4 of the intermediate piece 2.
- the vertical suspension not only improves the seating comfort, but also improves the active sitting position by superimposing vertical movements and tilting movements.
- the characteristic of the unstable equilibrium of the seat part 3 is determined by the restoring moment of the flexible membrane 6, which, in the embodiment of the invention shown in FIG. 1, simultaneously takes on the function of a restoring device that resets the unloaded Seat part 3 serves in the neutral position.
- the intermediate piece 2 has a second arcuate, resilient part 11, which is connected with its lower arm to the lower arm of the first arcuate part 4.
- the second arcuate part 11 is arranged within the first arcuate part 4 in such a way that a gap with increasing width forms with increasing distance from the connection point of the arcuate parts.
- REPLACEMENT LEAF 1 slidably arranged so that the hardness of the vertical suspension can be adjusted by means of the arcuate parts 4 and 11 by moving the wedge 12.
- the second arcuate part 11 has an elongated hole in a certain area of the upper arm, through which a threaded pin 13 of the wedge 12 projects.
- the wedge 12 can be fixed in a predetermined position between the ants of the arcuate parts 4 and 11.
- the locking nut 14 can be designed, for example, as a wing nut, so that the wedge 12 can be adjusted without tools.
- a bore 15 is provided in the front region of the upper arm of the arcuate part 11, which runs centrally to the bore 5 in the first arcuate part 4.
- the cylindrical part 7 of the seat part 3, which is supported by means of the flexible membrane 6 in the first arcuate part 4 of the intermediate piece 2, is designed such that its lower end also projects through the bore 15 in the second arcuate part 11. In this way, the maximum tilt angle of the seat part 3 is limited depending on the relation of the
- the seat part 3 of the seat device according to the invention shown in FIG. 1 can also be connected to the intermediate piece 2 by any other desired bearing, which allows a tilting movement in any lateral direction. This can be done, for example, by using a gimbal suspension of the seat part 3 in the intermediate piece 5 2.
- any other desired bearing which allows a tilting movement in any lateral direction.
- the foot part 1 and the seat part 3 are essentially identical to the corresponding parts of the exemplary embodiment shown in FIG. 1. Due to the different type of mounting of the seat part 3 on the intermediate piece 2, however, the use of the cylindrical part 7 in FIG. 1 can be dispensed with.
- the intermediate piece 2 consists of a lower hollow cylinder 21, which is arranged on the foot part 1 and rigidly connected thereto, and of an upper hollow cylinder 22, the inner diameter of which is only slightly larger than the outer diameter of the lower hollow cylinder 21, see above that the upper Hohlzy ⁇ cylinder 22 is guided in the vertical direction on the lower hollow cylinder 21.
- a resilient element 23 which is preferably designed as a helical spring and on the one hand acts on the foot part 1 or the lower wall of the lower hollow cylinder 21 and on the other hand the upper wall of the upper hollow cylinder 22.
- the resilient element 23 can be connected on its upper and lower sides to the upper wall of the upper hollow cylinder 22 and the base part 1 or the lower wall of the lower hollow cylinder 21 .
- the object can also be achieved in that the lower hollow cylinder 21 has an elongated hole which extends in the vertical direction and into which a horizontally extending pin connected to the upper hollow cylinder 22 engages. In this way, with a corresponding arrangement of the pin, pretensioning of the resilient element 23 can be achieved at the same time.
- the seat part 3 is connected to the upper hollow cylinder 22 of the intermediate piece 2 by means of several spring bands 24, which are distributed over the circumference of the plate 9 of the seat part 3.
- the spring bands 24 are preferably distributed at equidistant intervals over the circumference of the plate 9 of the seat part 3 or the circumference of the upper hollow cylinder 22 of the intermediate piece 2.
- the spring straps 24 can be shaped before being connected to the corresponding parts of the seat device such that they have a desired pretension after the connection. In this way, a desired hardness of the suspension of the seat part 3 can be set together with a ring 25, which is connected to the spring bands 24 at a predetermined height in a horizontal position.
- the ring 25 can be connected to the spring bands 24 so as to be displaceable in the vertical direction, so that a subsequent change in the spring characteristic is also possible.
- connection of the seat part 3 to the intermediate piece 2 by means of the spring straps 24 not only enables a pure tilting movement ttm a fixed point, but also smaller transverse movements of the seat part 3 or superimpositions of tilting and transverse movements . In this way, sitting on a ball is excellently approximated, which is recognized to have health-promoting effects.
