    • Ein erfindungsgemäßes Sitzkissen 1, wie es im Ausführungsbeispiel gezeigt wird, besteht bevorzugt aus weichelastischem Werkstoff, insbesondere weichelastischer Kunststoff-Folie, die z.B. gummielastische Eigenschaften besitzt.An inventive seat cushion 1, as in the embodiment is shown, preferably consists of soft elastic material, in particular soft elastic plastic film, e.g. rubbery Owns properties.

    Im gezeigten Ausführungsbeispiel besteht das Sitzkissen 1 aus einem Sitzflächenwandbereich 3, der im wesentlichen kreisrund ist, einem im wesentlichen gleich großen, ebenfalls kreisrunden Bodenflächenwandbereich 5 und einem Übergangswandbereich 7. Der Übergangswandbereich 7 verbindet den Sitzflächenwandbereich 3 mit dem Bodenflächenwandbereich 5 unter Ausbilden eines Wulstes, der bevorzugt eine halbrunde Querschnittsform aufweist.In the illustrated embodiment, the seat cushion 1 consists of a Sitzflächenwandbereich 3, which is substantially circular, a essentially the same size, also circular floor surface wall area 5 and a transition wall area 7. The transition wall area 7 connects the seat surface wall portion 3 with the bottom surface wall portion 5, forming a bead which is preferred has a semicircular cross-sectional shape.

    Wie im Ausführungsbeispiel gezeigt, kann der Übergangswandbereich 7 an seiner Außenseite mit wellenförmigen Zier- und/oder Verstärkungslinien 9, beispielsweise in Form vorspringender Rippen ausgebildet sein.As shown in the embodiment, the transition wall portion 7 on its outside with undulating ornamental and / or reinforcement lines 9, formed for example in the form of projecting ribs be.

    Auch ist gezeigt, daß bei unbelastetem Sitzkissen 1 der Sitzflächenwandbereich 3 und der Bodenflächenwandbereich 5 konvex sind, wobei die Konvexität des Sitzflächenwandbereiches 3 größer ist als jener des Bodenflächenwandbereiches 5.It is also shown that with unloaded seat cushion 1 of the seat area wall area 3 and the bottom surface wall portion 5 are convex, wherein the convexity of the seat surface wall portion 3 is larger than that the bottom surface wall region 5.

    Wie insbesondere den Fig. 2a und 3a zu entnehmen ist, besitzt das erfindungsgemäße Sitzkissen zwei Bereiche 11, die als Auflagen für Oberschenkel 13, insbesondere in deren an das Gesäß 15 eines Benutzers 17 angrenzenden Abschnitten dienen. Die Bereiche 11 werden in erster Linie vom Übergangswandbereich 7, der dort von der Mitte 19 des Sitzkissens 1 einen größeren Abstand aufweist, gebildet. Wie die Fig. 2b und 3b zeigen, ist die Außenform 21 des Übergangswandbereiches 7 im Bereich der Auflagen 11 für Oberschenkel 13 einer auf dem Sitzkissen 1 sitzenden Person 17 weitestgehend kreisbogenförmig (symbolisiert durch eingezeichnete Kreise).As can be seen in particular Figs. 2a and 3a, has the Seat cushion according to the invention two areas 11, which as supports for Thigh 13, in particular in the buttocks 15 of a user 17 adjoining sections serve. The areas 11 are in first line from the transition wall area 7, which is there from the middle 19 the seat cushion 1 has a greater distance formed. As the Figs. 2b and 3b show the outer mold 21 of the transition wall area 7 in the area of the pads 11 for thighs 13 one on the Seat cushion 1 seated person 17 largely circular arc (symbolized by drawn circles).

    Dabei ist es so, daß die beiden Auflagen bildenen Bereiche 11 voneinander Abstand besitzen. Der Abstand des Übergangswandbereiches 7 von der Mitte 19 des Sitzkissens 1 nimmt im Bereich der Auflagen bildende Bereiche 11 bis zur Mittelebene 23 jedes Bereiches 11 zu, wobei diese Zunahme des Abstandes stetig sein kann.It is so that the two editions forming areas 11 from each other Own distance. The distance of the transition wall area 7 from the center 19 of the seat cushion 1 takes in the area of the pads forming areas 11 to the center plane 23 of each area 11, this increase in the distance can be steady.

    Der Bodenflächenwandbereich 5 des erfindungsgemäßen Sitzkissen 1 ist bei unbelastetem Sitzkissen 1, also wenn keine Person 17 auf diesem sitzt, gegenüber dem tiefsten Bereich des vom Übergangswandbereich 7 gebildeten Randwulstes nach innen, also zur horizontalen Mittelebene des Sitzkissens 1 hin versetzt angeordnet. Dies zeigen insbesondere die Fig. 1, 2a und 3a.The bottom surface wall region 5 of the seat cushion 1 according to the invention is when unloaded seat cushion 1, so if no person 17 on this sits opposite the deepest area of the transition wall area 7 formed edge bead inward, so the horizontal center plane arranged offset of the seat cushion 1. This is shown in particular Figs. 1, 2a and 3a.

    Wenn das Sitzkissen 1 zum Sitzen benützt wird, wird es so ausgerichtet, daß die ohrförmigen, Auflagen bildenden Bereiche 11 unterhalb der Oberschenkel 13 eines Benützers 17 angeordnet sind, wie dies in Fig. 4 symbolisch dargestellt ist.When the seat cushion 1 is used for sitting, it is aligned that the ear-shaped, pads forming areas 11 below the thighs 13 of a user 17 are arranged, such as this is shown symbolically in FIG. 4.

    Die Wandbereiche 25 zwischen dem Sitzflächenwandbereich 3 und zwischen dem Bodenflächenwandbereich 25 und dem Randwulst, der vom Übergangswandbereich 7 gebildet wird, sind in den Bereichen 11 im wesentlichen (mond-) sichelförmig ausgebildet und bei unbelastetem Sitzkissen 1 im wesentlichen eben. Dadurch werden insbesondere im Anschluss an den Sitzflächenwandbereich 3 gute Auflagen für die Oberschenkel 13 einer auf dem Sitzkissen 1 sitzenden Person 17 gebildet.The wall portions 25 between the seat surface wall portion 3 and between the bottom surface wall region 25 and the edge bead of the Transition wall region 7 is formed in the areas 11 in essentially (moon-) crescent-shaped and in unloaded Seat cushion 1 essentially flat. This will be especially in the Connection to the seat wall area 3 good conditions for the Thigh 13 of a person sitting on the seat cushion 1 17 educated.

    Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt dargestellt werden: In summary, an embodiment of the invention as follows:

    Ein Sitzkissen 1 mit einem Sitzflächenwandbereich 3 und einem Bodenflächenwandbereich 5 weist einen wulstförmigen Übergangswandbereich 7 auf, der den Sitzflächenwandbereich 3 mit dem Bodenflächenwandbereich 5 verbindet. So liegt ein fluiddichtes Kissen 1 vor, das über eine verschließbare Füllöffnung mit Luft gefüllt werden kann. In zwei mit Abstand voneinander benachbarten Bereichen 11 ist der Abstand des Übergangswandbereiches 7 von der Mitte 19 des Sitzkissens 1 vergrößert, wodurch in Draufsicht linsenförmige, über die vom Übergangswandbereich 7 sonst bestimmte, im wesentlichen kreisförmige Umrißform des Sitzkissens 1 seitlich vorstehende Bereiche 11 gebildet sind. Diese vorspringenden Bereiche 11 sind Auflagen für Oberschenkel 17 einer auf dem Sitzkissen 1 sitzenden Person 17. Dies ergibt auch bei kleinem Durchmesser des im allgemeinen kreisflächenförmigen Sitzkissens 1 einen guten Sitzkomfort, da die Oberschenkel 13 wenigstens im an das Gesäß 15 anschließenden Bereich durch die vorspringenden Auflagen 11 abgestützt sind, wie dies sonst nur bei einem Sitzkissen mit insgesamt größerem Durchmesser gegeben wäre.A seat cushion 1 having a seat surface wall portion 3 and a bottom surface wall portion 5 has a bead-shaped transition wall area 7, showing the seat surface wall portion 3 with the bottom surface wall portion 5 connects. So there is a fluid-tight pad 1, the can be filled with air via a closable filling opening. In two spaced apart adjacent areas 11 of the Distance of the transition wall portion 7 of the center 19 of the seat cushion 1 enlarged, whereby lenticular in plan view, on the Transition wall portion 7 otherwise certain, substantially circular Outline shape of the seat cushion 1 laterally projecting portions 11 formed are. These projecting portions 11 are requirements for Thigh 17 of a person sitting on the seat cushion 1 17. This even with a small diameter of the generally circular-shaped Seat cushion 1 a good sitting comfort, as the thighs 13 at least in the adjoining the buttocks 15 area by the projecting pads 11 are supported, as otherwise only in a seat cushion with an overall larger diameter would be given.
