Description

Die Erfindung bezieht sich auf einen Sitz zur Lockerung und Entspannung des Stützapparates des menschlichen Benutzers entlang der gesamten Wirbelsäule speziell aber im Lendenwirbelsäulen Beckenbereich durch einfaches Sitzen, umfassend eine Sitzfläche (2), eine nocke (8) und mindestens eine lage von Schaumstoff, wobei die Sitzfläche um die Sitzfläche um einen ungefähr in der Mitte der Sitzfläche befindlichen Drehpunkt gekippt werden kann wobei die Kippung der Sitzfläche um einen auf dem Scheitelpunkt der Nocke befindlichen Drehpunkt erfolgt.The invention relates to a seat for loosening and relaxation of the human user's support apparatus along the entire spine, but especially in the lumbar spine of the pelvic region by simple sitting, comprising a seat (2), a cam (8) and at least one layer of foam Seat can be tilted about the seat around a pivot point located approximately in the center of the seat, wherein the tilting of the seat is carried about a pivot point located on the vertex of the cam.

Durch die Erfindung soll es dem Benutzer ermöglicht werden, im Sitzen die tragenden Strukturen der Bereiche der unteren Wirbelsäule und des Beckens zu bewegen und zu lockern, aber diese auch endlagig durch feste Stützung zu entlasten und auszuruhen.By the invention it should be possible for the user to move while sitting the supporting structures of the areas of the lower spine and the pelvis and relax, but also relieve them endlagig by solid support and rest.

Es ist ein Faktum, daß viele Arbeitstätigkeiten in industrialisierten Nationen durch monotone Bewegungen vollbracht werden, wobei dabei zumeist eine sitzende Position eingenommen wird. Dies hat zur Folge, daß viele Menschen an den Auswirkungen von Haltungsschäden leiden.It is a fact that many work activities in industrialized nations are accomplished by monotonous movements, usually taking a seated position. As a result, many people suffer from the effects of postural disorders.

Das Zusammenwirken des passiven und des aktiven Haltungsapparates (Knochen, Bänder, Muskeltonus) sowie der Stoffwechsel des Gewebes (Übersäuerung, Verquellungen etc.) variiert je nach Alter, Kräftezustand, seelischer Verfassung und Veranlagung des Betroffenen. Lockernde Bewegung sowie Steck- und Dehnübungen sind geeignet, diese schmerzhaften Auswirkungen von Haltungsschäden zumindest zu lindern und wirken auch sonst gesundheitsfördernd. Zu beachten ist, daß die meisten der bisher bekannten lockernden Übungen nicht während der Arbeitstätigkeit durchgeführt werden können, sondern Freizeit für diese zusätzlichen Übungen "geopfert" werden muß.The interaction of the passive and the active attitude apparatus (bones, ligaments, muscle tone) as well as the metabolism of the tissue (hyperacidity, swelling, etc.) varies depending on the age, state of strength, emotional state and disposition of the affected person. Relaxing movement as well as stretching and stretching exercises are suitable to alleviate these painful effects of postural damage or at least have a health-promoting effect. It should be noted that most of the loosening exercises known so far can not be performed during the work activity, but leisure must be "sacrificed" for these additional exercises.

Nach der JP 55108323 A ist ein Sitz zur Lockerung und Entspannung des Stützapparates bekannt, welcher eine Kippbewegung der Sitzfläche durch die Aufnahme eines schüsselförmigen Wippelementes erreicht.According to JP 55108323 A a seat for loosening and relaxation of the support apparatus is known, which achieves a tilting movement of the seat by receiving a bowl-shaped rocker element.

Es ist ein Ziel der vorliegenden Erfindung, einen Sitz zu schaffen, der sowohl im betrieblichen als auch im privaten Bereich Verwendung finden kann und der neben seinem primären Zweck -dem Sitzen- auch die wichtige Lockerung zur Verbesserung der Perfusion und somit der Versorgung und Entsäuerung des entsprechenden Gewebes ermöglicht, wobei sich die Entdeckung der Arbeitsmedizin zu Nutze gemacht wird, daß weder eine ständige Ruhigstellung noch ständige Bewegung prinzipiell gesund, sondern nur das dem momentanen Bedürfnis adäquate Verhalten wohltuend ist.It is an object of the present invention to provide a seat which can be used both in the workplace and in the private sector and which, in addition to its primary purpose of sitting, also the important relaxation to improve the perfusion and thus the supply and deacidification of the appropriate tissue is made, whereby the discovery of occupational medicine is made use of, that neither a constant immobilization nor constant movement in principle healthy, but only the current need adequate behavior is beneficial.

Erreicht wird dies dadurch, daß der Drehpunkt in der Höhe veränderbar ausgebildet ist und das Kippen der Sitzfläche durch eine Lage von weichem und nachgiebigem Schaumstoff sowie durch eine zweite Lage von festerem Schaumstoff gedämpft wird. Die erfindungsgemäße Anordnung hat zur Folge, daß die Sitzfläche um einen individuell wählbare Mittellage zur Lockerung und Entspannung des Halteapparates mäßig beweglich, aber auch durch den Sitz so von einem fixen, begrenzenden Rahmen umgeben ist, daß auch ein entspanntes Hineinlehnen in den Sitz möglich ist. Dadurch können die lockernden Übungen durch vor-, rück- und seitwärtiges Kippen sowie durch kombiniertes Kreisen des Beckens mehr oder weniger unbewußt während des Arbeitsvorganges stattfinden und sogar neben der Verhinderung der Belastung durch relativ zwingende Haltungskonstanz sogar eine Erleichterung haltungsbedingter Beschwerden bewirken. Adäquate Wirkungen könnten sonst nur durch gymnastische Übungen außerhalb der Arbeitstätigkeit erreicht werden.This is achieved in that the pivot point is designed to be variable in height and the tilting of the seat is damped by a layer of soft and resilient foam and by a second layer of firmer foam. The arrangement according to the invention has the consequence that the seat to an individually selectable center position for loosening and relaxation of the holding apparatus is moderately movable, but also surrounded by the seat of a fixed, limiting frame that even a relaxed leaning back into the seat is possible. As a result, the loosening exercises by forward, backward and sideways tilting and combined circles of the pelvis more or less unconsciously take place during the work process and even cause in addition to preventing the burden of relatively compelling attitude constancy even a relief attitude-related complaints. Otherwise, adequate effects could only be achieved through gymnastic exercises outside of work.

Das Vorsehen von unterschiedlichen Lagen von Schaumstoff fördert ein entspanntes Hineinlehnen in den Sitz. Es können aber auch noch andere Polsterungs- oder Federungsmöglichkeiten, wie z.B. Stahlfedem oder Plastikbällchen hohl oder flussigkeitsgefüllt etc. für weitere Einsatzmöglichkeiten vorgesehen werden.The provision of different layers of foam promotes relaxed leaning back into the seat. However, other padding or suspension options may also be used such as cushioning. Stahlfedem or plastic balls hollow or liquid filled etc. are provided for other uses.

Um den Sitz individuell an den Benützer anpassen zu können und um ein bequemes und immer wieder veränderbares Sitzen zu ermöglichen, ist es zweckmäßig, daß der Drehpunkt der Sitzfläche in der Ebene der Sitzfläche verschoben werden kann.In order to customize the seat individually to the user and to allow a comfortable and repeatedly changing seats, it is appropriate that the pivot point of the seat in the plane of the seat can be moved.

Um ein bequemes Anlehnen des Oberkörpers zu ermöglichen, kann bei der gegenständlichen Erfindung eine Sitzlehne mit zwei an ihrer Rückseite verschiebbaren Lordosenstützen vorgesehen werden, die ihre Kippachse nicht wie üblich in der Sitzhöhe hat, sondern im Vergleich zu dem allgemein üblichen Modus wesentlich nach oben versetzt -in der Höhe etwa des Überganges von der Brust zur Lendenwirbelsäule bei einem normal großen, sitzenden Erwachsenen- hat. Dadurch kann sich die Rückenlehne -durch Schaumstoff oder, wie oben schon bei der Sitzfläche besprochen, anders gefedert- immer abhängig von der jeweiligen Stellung des Beckens an die Lendenwirbelsäule stützend anlehnen. Damit wird das "dynamische" Sitzen und das "statische" Ausruhen des Benutzers noch besser ermöglicht. Üblicherweise werden bei der gegenständlichen Erfindung auch höhenverstellbare Armlehnen vorgesehen sein, die zusätzlich noch mit Achselstücken versehen sein können, um ein "Hineinhängen" des Benutzers zu ermöglichen.In order to allow a comfortable leaning of the upper body, in the subject invention, a seat back with two slidable on its back lumbar supports are provided, which does not have its tilt axis as usual in the seat height, but in comparison to the usual mode substantially upwards - at the level of about the transition from the chest to the lumbar spine in a normally large, seated adult has. As a result, the backrest-by foam or, as already discussed above in the seat, sprung differently- always support depending on the respective position of the pelvis to the lumbar spine supporting. This allows even more "dynamic" sitting and "static" rest of the user. Usually height-adjustable armrests will be provided in the subject invention, which may additionally be provided with shoulder pieces to allow a "Hineinhängen" of the user.

Nachstehend ist die Erfindung anhand eines Ausführungsbeispieles beschrieben, welches in den Zeichnungen dargestellt ist, wobei die Erfindung keinesfalls auf dieses Beispiel beschränkt ist.

  • Dabei zeigt die Fig. 1 einen erfindungsgemäßen Sitz in einer Totalen;
  • weiters stellt Fig. 2 einen Kippmechanismus eines erfindungsgemäßen Sitzes in Ansicht dar;
  • Fig. 3 zeigt in schaubildlicher Ansicht einen Teil des Kippmechanismus der Erfindung und
  • Fig. 4 zeigt einen Teil des bereits in Fig. 3 gezeigten Teiles des Kippmechanismus in Seitenansicht.
The invention will now be described by means of an embodiment shown in the drawings, the invention being by no means limited to this example.
  • 1 shows a seat according to the invention in a long shot;
  • 2 further illustrates a tilting mechanism of a seat according to the invention in view;
  • Fig. 3 shows a perspective view of a part of the tilting mechanism of the invention and
  • Fig. 4 shows a part of the already shown in Fig. 3 part of the tilting mechanism in side view.

Gemäß der Fig. 1 besteht ein Sitz 1 aus einer Sitzfläche 2, einer Lehne 3, einem Kippmechanismus 4 und einer Gasdruckfeder 5. Der Kippmechanismus 4 befindet sich auf einer Halteplatte 6, wobei sich oberhalb dieses Kippmechanismus 4 eine Widerlagerplatte 18 samt Sitzfläche 2 befindet.1, a seat 1 consists of a seat 2, a backrest 3, a tilting mechanism 4 and a gas spring 5. The tilting mechanism 4 is located on a holding plate 6, wherein above this tilting mechanism 4 is an abutment plate 18 including seat 2.

In der gegenständlichen Figur nicht gezeigt sind mögliche Armlehnen am Rande der Sitzfläche 2; am unteren Ende der Gasdruckfeder 5 befinden sich die (nicht gezeigten) Füße des Sitzes 1, in der Regel wird wohl ein Fünf-Sterne-Fußkreuz angelenkt sein.Not shown in the figure, possible armrests on the edge of the seat 2; at the lower end of the gas spring 5 are the (not shown) feet of the seat 1, usually a five-star base will probably be articulated.

Die nicht gezeigten Armlehnen können höhenverstellbar angeordnet werden, wobei es auch möglich ist die Armlehnen mittels (in der Figur nicht gezeigten) Achselstücken zu versehen, in die sich der Benutzer zur Entlastung seines Stützapparates (Wirbelsäule etc.) einhängen kann. Möglich ist auch, daß die Lehne 3 in an und für sich bekannter Weise höhenverstellbar, respektive neigbar angeordnet ist.The armrests, not shown, can be arranged adjustable in height, wherein it is also possible to provide the armrests by means (not shown in the figure) Achselstücken, in which the user can hang to relieve his spine (spine, etc.). It is also possible that the backrest 3 is arranged in a manner known per se height adjustable, respectively inclinable.

Die Fig. 2 zeigt die Halteplatte 6 in einer Draufsicht, die oberhalb der Halteplatte 6 befindliche Sitzfläche 2 samt Widertagerplatte 18 ist nicht gezeigt.2 shows the holding plate 6 in a plan view, the seating surface 2 located above the holding plate 6 together with the counter bearing plate 18 is not shown.

Die Kippung der Sitzfläche 2 und der damit verbundenen Widerlagerplatte 18 wird dadurch erreicht, daß eine auf einer Flügelstange 7 angelenkte Nocke 8 die Widerlagerplatte 18 ungefähr mittig anhebt, sodaß die Widerlagerplatte 18 (samt der oberhalb befindlichen Sitzfläche 2) um den auf dem Scheitelpunkt der Nocke 8 befindlichen Drehpunkt gekippt werden kann.The tilting of the seat 2 and the associated abutment plate 18 is achieved in that a hinged on a wing rod 7 cam 8 raises the abutment plate 18 approximately centrally, so that the abutment plate 18 (including the above seat surface 2) to that on the vertex of the cam 8 located pivot point can be tilted.

Durch Verdrehen der Flügelstange 7 (samt Nocke 8) verändert sich der Drehpunkt in der Höhe, wobei dadurch einmal ein größerer und einmal ein kleinerer möglicher Neigungswinkel der Sitzfläche 2 erreicht wird. Durch ein Vor- oder Zurückschieben in pfeilrichtung p' der Flügelstange 7 samt der Nocke 8 kann der Drehpunkt etwas vom Mittelpunkt der Halteplatte 6 weg verlagert werden.By turning the wing rod 7 (including cam 8), the pivot point changes in height, thereby once a larger and even a smaller possible angle of inclination of the seat 2 is achieved. By a forward or backward sliding in the arrow direction p 'of the wing rod 7 together with the cam 8, the pivot point can be shifted slightly away from the center of the retaining plate 6.

Die Halteplatte 6 ist aus mehreren Schichten Material aufgebaut, die das Kippen der Sitzfläche 2 dämpfen. Eine Grundplatte 9 (vorzugsweise aus Holz ausgebildet) ist mit einer Lage aus festem Schaumstoff 10 und einer Lage aus weichem Schaumstoff 11 verbunden. Dies hat zur Folge, daß trotz einer Höhenverstellung durch ein Verdrehen der Nocke 8 mit Hilfe der Flügelstange 7 sowohl eine leichte wie auch eine kräftige Komponente des Kippens erhalten bleibt. Ein derartiges Sitzgefühl wird vom Benutzer als angenehm empfunden.The holding plate 6 is constructed of several layers of material that dampens the tilting of the seat 2. A base plate 9 (preferably made of wood) is provided with a Layer of solid foam 10 and a layer of soft foam 11 connected. This has the consequence that despite a height adjustment by turning the cam 8 by means of the wing rod 7 both a light and a strong component of tilting is maintained. Such a seat feeling is perceived by the user as pleasant.

Nicht gezeigt sind weitere aber bekannte Federungsmöglichkeiten (Federn etc.), welche anstatt der Lage aus festem Schaumstoff 10 und der Lage aus weichem Schaumstoff 11 eingesetzt werden können.Not shown are other but known suspension options (springs, etc.), which instead of the layer of solid foam 10 and the position of soft foam 11 can be used.

Zwei kleine Tramportschienen 12 an den Positionen P' und P", die in Folge ihrer zweifachen Kröpfung 13 in die im rechten Winkel an der Flügelslange 7 entsprechend angesetzten Tramportflügel 14 einrasten, laufen in ihren beiden queren Rillen 15' und 15" und bewegen beim drehenden Verstellen der Nocke 8 die Fixierblöcke 16. Diese Fixierblöcke 16 sind an den Enden der Transportschiene 12 mit dieser verbunden. Die Fixierblöcke 16 kommen in der Feststellposition direkt unter Fixierblöcken 17 zu liegen, die auf der Widerlagerplatte 18 angebracht sind (sichtbar in Fig. 1).Two small Tramportschienen 12 at the positions P 'and P ", which engage as a result of their double crank 13 in the at right angles to the wing length 7 appropriately scheduled Tramportflügel 14, run in their two transverse grooves 15' and 15" and move the rotating Adjusting the cam 8, the fixing blocks 16. These fixing blocks 16 are connected at the ends of the transport rail 12 with this. The fixing blocks 16 come to lie in the locking position directly under fixing blocks 17 which are mounted on the abutment plate 18 (visible in Fig. 1).

Durch die in der Zeichnung gezeigte besondere Form der Halteplatte 6 wird eine stäkere Kippung des Sitzes 1 nach vorne, eine schwächere Kippung nach hinten und ein wesentlich geringeres Auslenken zu den Seiten hin erlaubt. Diese Anordnung kommt den physiologischen Bedürfnissen der Mobilitäten normaler Wirbelsäulen entgegen und ist daher medizinisch von Vorteil.Due to the particular shape of the holding plate 6 shown in the drawing, a stäkere tilting of the seat 1 to the front, a weaker tilt to the rear and a much lower deflection is allowed to the sides. This arrangement accommodates the physiological needs of the mobilities of normal spine and is therefore medically beneficial.

Zugfedern 19 auf beiden Seiten der zentralen Ausnehsnung 20 der Nocke 8 in der Halteplatte 6 sorgen für den nötigen ständigen Anpreßdruck der Halteplatte 6 samt der Sitzfläche 2 an die Nocke 8. Bohrungen 21 erlauben ein Anlenken der Halteplatte 6 an die Gasfeder 5.Tension springs 19 on both sides of the central Ausnehsnung 20 of the cam 8 in the support plate 6 provide the necessary constant contact pressure of the support plate 6 together with the seat 2 to the cam 8. Holes 21 allow a hinging of the support plate 6 to the gas spring. 5

Gemäß der Fig. 3 ist auf der Flügelstange 7 eine Nocke 8 angelenkt. Auf beiden Seiten der Nocke 8 befinden sich die Transportflügel 14.According to FIG. 3, a cam 8 is articulated on the wing rod 7. On both sides of the cam 8 are the transport wings 14th

Fig. 4 zeigt die Nocke 8. Auf drei Vierteln ihres Umfanges weist die Nocke 8 im Mittel den gleichen Abstand von ihrem Zentrum und nur in einem Viertel einen größeren Abstand von ihrem Zentrum auf. An der Basisseite und an der der exzentrischen Seite gegenüberliegenden Seite ist die Nocke 8 tangential eine kurze Strecke gerade (an der Stelle P"') und nicht bombiert, also flach, und nur mit gerundeten Übergängen versehen. Dies gewährleistet ein Fixieren der gewählten Einstellung. Für den Benutzer wird subjektiv ein "Einrasten" erfolgen.Fig. 4 shows the cam 8. On three quarters of its circumference, the cam 8 has on average the same distance from its center and only in one quarter a greater distance from its center. On the base side and on the side opposite the eccentric side, the cam 8 is tangential for a short distance straight (at the point P "') and not cambered, ie flat, and provided only with rounded transitions, ensuring a fixation of the selected setting. Subjectively, the user will be "snapped".
