Description

Die vorliegende Erfindung betrifft einen Hohlkörper für die Benutzung als Sitzunterlage gemaß dem Oberbegriff des Anspruchs 1. Ein derartiger Hohlkörper ist bereits aus der DE-U-8806782 bekannt.The present invention relates to a hollow body for use as Seat pad according to the preamble of claim 1. Such Hollow body is already known from DE-U-8806782.

Der aus der DE-U-8806782 bekannte Gegenstand ist jedoch gewölbt und für langanhaltende Meditationsstellungen vorgesehen. Durch die Wölbung soll das Meditationskissen in unterschiedlichen Positionen am Boden fixierbar sein, beispielsweise auch in geneigter Position. Ausgleichsbewegungen in Form eines dynamischen Sitzens ermöglicht das vorbekannte Meditationskissen nicht. Vielmehr ermöglicht die ballig abgeschrägte bzw. keilförmige Sitzfläche eine besondere Meditationshaltung. Schließlich ist das vorbekannte Kissen aufgrund seiner relativen Höhe nur bedingt als Sitzunterlage geeignet. The object known from DE-U-8806782, however, is curved and for long-lasting meditation positions provided. Due to the curvature Meditation cushions can be fixed in different positions on the floor, for example in an inclined position. Compensatory movements in the form of a The known meditation cushion does not allow dynamic sitting. Rather, the spherically bevelled or wedge-shaped seat enables special meditation posture. After all, the known pillow is due its relative height is only partially suitable as a seat pad.

Es sind allgemein Sitzunterlagen bekannt, welche kissenförmig (Sitzkissen) ausgestaltet sind. Diese Sitzunterlagen sind einerseits mit elastischem bzw. federndem Füllmaterial gefüllt, z.B. mit Federn, Schaumstoff oder dgl., und andererseits als Luftkissen ausgestaltet, wobei die Steifigkeit der Sitzunterlage durch ein in der Sitzunterlage eingeschlossenes Gasvolumen erreicht wird.Seat pads are generally known which are cushion-shaped (seat cushions) are designed. These seat pads are on the one hand with elastic or resilient filling material, e.g. with feathers, foam or the like, and on the other hand designed as an air cushion, the rigidity of the seat pad is achieved by a gas volume enclosed in the seat pad.

Diese bekannten Sitzunterlagen führen jedoch zu einer Sitzstellung, welche ergonomisch inkorrekt ist und zu Dauerfehlbelastungen des Körpers führt. Verkrampfungen, Verspannungen oder gar bleibende gesundheitliche Schäden (z.B. Verkrümmungen der Wirbelsäule) können dadurch verursacht werden.However, these known seat pads lead to a seating position, which is ergonomically incorrect and leads to permanent incorrect strain on the body. Cramping, tension or even permanent health damage (e.g. curvature of the spine) can be caused.

Es ist andererseits bekannt, daß Sitzbälle eine ergonomisch vorteilhafte Sitz-Stellung herbeiführen, indem der Körper zu andauernden Ausgleichbewegungen (dem sogenannten "dynamischen Sitzen") angeregt wird.On the other hand, it is known that seat balls have an ergonomically advantageous sitting position induce the body to constant balancing movements (the so-called "dynamic sitting") is stimulated.

Wegen ihrer Form brauchen solche Sitzbälle eine Unterlage bzw. Haltekonstruktion, damit sie nicht wegrollen. Staatliche Institutionen, z.B. Schulen, haben insbesondere wegen der Wegrollgefahr solcher Sitzbälle deren Einsatz in öffentlich zugänglichen Bereichen untersagt. Falls eine Rückenlehne für den Sitz erwünscht ist, ist die Haltekonstruktion aufwendiger und somit teurer.Because of their shape, such seat balls need a support or support structure, so that they don't roll away. State institutions, e.g. Schools, have especially because of the risk of such balls rolling away, their use in public accessible areas prohibited. If a backrest for the seat is desired, the support structure is more complex and therefore more expensive.

Aufgabe der vorliegenden Erfindung ist es, eine Sitzunterlage mit einer einfachen Ausgestaltung und Handhabung bereitzustellen, welche beim Gebrauch eine ergonomisch vorteilhafte Sitzstellung bzw. -haltung, insbesondere ein dynamisches Sitzen, der darauf sitzenden Person herbeiführt.The object of the present invention is to provide a seat pad with a simple To provide design and handling, which in use a ergonomically advantageous sitting position or posture, especially a dynamic one Sitting, which brings about the person sitting on it.

Diese und weitere Aufgaben werden durch einen Hohlkörper gemäß Anspruch 1 gelöst.These and other tasks are achieved by a hollow body according to claim 1 solved.

Ein Hohlkörper gemäß der vorliegenden Erfindung führt zu einem dynamischen Sitzen der auf dem Hohlkörper sitzenden Person, wodurch Verspannungen, Dauerfehlbelastungen, Nervenreizungen und Schmerzzustände im Lenden- und Wirbelsäulenbereich vermieden oder z.T. gemindert oder geheilt werden.A hollow body according to the present invention leads to a dynamic one Sitting of the person sitting on the hollow body, causing tension, Permanent maltreatment, nerve irritation and pain in the lumbar and Spine area avoided or partially be diminished or cured.

Zusätzlich zu diesen orthopädischen Vorteilen kann der erfindungsgemäße Hohlkörper wegen seiner Formgestaltung auch in öffentlich zugänglichen Bereichen eingesetzt werden, da durch die ebene Auflagefläche keine Wegrollgefahr besteht.In addition to these orthopedic advantages, the invention Hollow body because of its shape also in publicly accessible areas be used, since there is no risk of rolling away due to the flat contact surface consists.

Der erfindungsgemäße Hohlkörper kann wegen seiner Ausgestaltung weiterhin als Auflage für bekannte Stühle mit Rückenlehne dienen, wodurch z.B. eine für die Sitzbälle unabdingbare teure Unterkonstruktion bzw. Tragestruktur nicht mehr notwendig ist und der Hohlkörper wird somit umproblematisch eingesetzt. Es wird außerdem insbesondere ein "Nachrüsten" der schon vorhandenen Sitzmöglichkeiten bzw. Stühle möglich, da insbesondere die maximale Abmessung des Hohlkörpers bevorzugt an die Größe der Sitzfläche gängiger Stühle angepaßt ist.The hollow body according to the invention can continue because of its design serve as a support for known chairs with a backrest, which means e.g. one for the seat balls do not have an expensive substructure or support structure is more necessary and the hollow body is thus used without problems. It will also be a "retrofitting" of the existing ones Seating or chairs possible, especially because of the maximum dimensions of the hollow body preferred to the size of the seat of common chairs is adjusted.

Die in Fig. 1 und 2 dargestellte Ausführungsform der vorliegenden Erfindung in Form eines Hohlkörpers bzw. Sitzscheibe bzw. Hohlscheibe umfaßt einen flachen Sitzbereich 10, einen flachen Auflagebereich 20 und einen dazwischen angeordneten, den Übergang zwischen dem Sitzbereich 10 und dem Auflagebereich 20 bildenden wulstförmigen Übergangsbereich 30. Wenn der Hohlkörper mit seinem Auflagebereich 20 z.B. auf einem (nicht dargestellten) Stuhl aufliegt, paßt sich die Form des Auflagebereiches 20 wegen der Elastizität der Hohlkörperhaut 42 an die Form des Stuhles an, welche im allgemeinen flach ist. Der Übergangsbereich 30 gleicht z.T. eventuell auftretende Unregelmäßigkeiten aus.The embodiment of the present invention shown in Figs. 1 and 2 in The shape of a hollow body or seat disc or hollow disc comprises a flat one Seat area 10, a flat support area 20 and an intermediate one, the transition between the seating area 10 and the support area 20 forming bead-shaped transition region 30. When the hollow body with its support area 20 e.g. lies on a chair (not shown), fits the shape of the support area 20 because of the elasticity of the hollow skin 42 to the shape of the chair, which is generally flat. Of the Transition area 30 is partially irregularities that may occur.

Sobald eine Person auf dem Hohlkörper sitzt, paßt sich der Sitzbereich 10 an die Anatomie der Person an. Der wulstförmige bzw. abgerundete Übergangsbereich 30 überträgt die Belastung auf den Auflagebereich 20, welcher auf dem Stuhl aufliegt und sich darauf abstützt. Der wulstförmige Übergangsbereich kann insbesondere einen halbrunden oder halb-elliptischen Querschnitt aufweisen oder spitz zulaufen.As soon as a person sits on the hollow body, the seating area 10 adapts to the Anatomy of the person. The beaded or rounded transition area 30 transfers the load to the support area 20, which is on the chair rests and is supported on it. The bead-shaped transition area can in particular have a semicircular or semi-elliptical cross section or taper to a point.

Die Hohlkörperhaut 40, welche insbesondere aus zwei miteinander verbundenen, bevorzugt identischen Formteilen 40' und 40'' (Fig. 2), insbesondere aus weichgemachtem Polyvinylchlorid (PVC), gebildet ist, weist vorspringende Anformungen 42, 42', 42'' auf dem Sitzbereich 10 und/oder vorspringende Anformungen 44, 44', 44'' auf dem Auflagebereich 20 auf. Diese Anformungen dienen einerseits zur Versteifung des Hohlkörpers, und andererseits zur Erhöhung der Rutschfestigkeit des Sitz- und/oder des Auflagebereiches sowie auch zur ästhetischen Ausgestaltung des Hohlkörpers an sich.The hollow body skin 40, which in particular consists of two interconnected, preferably identical molded parts 40 'and 40' '(Fig. 2), in particular made of plastic Polyvinyl chloride (PVC) is formed, has protruding formations 42, 42 ', 42' 'on the seating area 10 and / or protruding formations 44, 44 ', 44' 'on the support area 20. These formations serve on the one hand to stiffen the hollow body, and on the other hand to increase the Slip resistance of the seat and / or the support area as well as the aesthetic Design of the hollow body itself.

Der Hohlkörper umfaßt weiterhin ein Ventil 50, durch welches der Druck im Innenraum bzw. das Innenvolumen des Hohlkörpers eingestellt werden kann. Der Hohlkörper weist insbesondere wegen des niedrigen Innendrucks bzw. einer geringen Dehnung der Hohlkörperhaut eine gute Reißfestigkeit auf.The hollow body further comprises a valve 50 through which the pressure in Interior or the internal volume of the hollow body can be adjusted. Of the Hollow body has in particular because of the low internal pressure or low elongation of the hollow skin has good tear resistance.

In einer nicht dargestellten Ausführungsform der vorliegenden Erfindung weist die Hohlkörperhaut auch in dem Übergangsbereich vorspringende Anformungen auf.In an embodiment of the present invention, not shown the hollow body skin also protrudes in the transition area on.

Der Hohlkörper weist eine maximale Abmessung, insbesondere eine Breite D, auf, welche der Sitzfläche eines Stuhls angepaßt ist und etwa 35 cm beträgt. Bevorzugt ist der Hohlkörper ein in der Draufsicht rundes oder ovales Gebilde, wodurch ein vorteilhaft gutes "dynamisches Sitzverhalten" der auf dem Hohlkörper sitzenden Person erreicht wird.The hollow body has a maximum dimension, in particular a width D, on which is adapted to the seat of a chair and is about 35 cm. The hollow body is preferably a round or oval structure in plan view, whereby an advantageously good "dynamic seating behavior" of the on the hollow body seated person is reached.

Die Höhe H des Hohlkörpers beträgt insbesondere etwa 8 bis 10 cm und ist insbesondere derart, daß wenn der Hohlkörper auf einem Stuhl mit Rückenlehne benutzt wird, die darauf sitzende Person sich bequem an die Rückenlehne des Stuhles lehnen kann. Dieses Erfordernis erlaubt vorteilhaft den Einsatz z.B. in Schulen, in denen es zur Herabsetzung der Verletzungsgefahr der Kinder vorgeschrieben ist, daß die Stühle hinreichende Rückenlehnen haben sollen. The height H of the hollow body is in particular about 8 to 10 cm and is in particular such that when the hollow body on a chair with a backrest is used, the person sitting on it comfortably on the backrest of the Chair can lean. This requirement advantageously allows use e.g. in Schools where it is prescribed to reduce the risk of injury to children is that the chairs should have adequate backrests.

Fig. 3 stellt schematisch die durch eine auf dem Hohlkörper 100, 100' sitzende Person 110, 110' erzeugten Bewegungen dar. Die Bewegungen sind zur Veranschaulichung übertrieben dargestellt.Fig. 3 shows schematically the one sitting on the hollow body 100, 100 ' Person 110, 110 'generated movements. The movements are illustrative exaggerated.

Die elastische Ausgestaltung der Haut des Hohlkörpers 100, 100', welche insbesondere aus weichgemachtem Polyvinylchlorid gebildet ist, bewirkt, wie auch bei den bekannten Sitzbällen, daß ein Teil der durch die Belastung der Person erzeugten Kräfte in Scherkräfte bzw. zu der Fläche 120 des Stuhls im wesentlichen parallele Kräfte umgesetzt werden. Diese Scherkräfte bewirken leichte Kipp- bzw. Wipp-Bewegungen (in Fig. 3 durch den Doppelpfeil B angedeutet) der auf dem Hohlkörpersitzenden Person 110, 110'. Der Hohlkörper 100 kann sich unter dieser verschiedenartigen Belastung verformen (vgl. unter 100') und folgt den Bewegungen der Person.The elastic configuration of the skin of the hollow body 100, 100 ', which is formed in particular from plasticized polyvinyl chloride, causes how also in the known seat balls that part of the stress caused by the Person generated forces in shear forces or to the surface 120 of the chair in the essential parallel forces are implemented. These shear forces cause slight tilting or rocking movements (indicated by the double arrow B in FIG. 3) the person sitting on the hollow body 110, 110 '. The hollow body 100 can deform under this diverse load (see under 100 ') and follows the movements of the person.

Dieses als "dynamische Sitzen" bekannte Verhalten führt zu den obengenannten orthopädischen und ergonomischen Vorteilen und erzeugt somit ein Wohlbehagen der auf dem Hohlkörper sitzenden Person.This behavior known as "dynamic sitting" leads to the above orthopedic and ergonomic advantages and thus creates a sense of well-being the person sitting on the hollow body.
