Description

Die Erfindung betrifft ein Sitzkissen mit den Merkmalen des einleitenden Teils von Anspruch 1.The invention relates to a seat cushion with the features of the introductory part of claim 1.

Ein derartiges Sitzkissen ist aus der DE-U-296 22 187 bekannt.Such a seat cushion is from the DE-U-296 22 187 known.

Ähnliche Sitzkissen sind aus der US-A-5 634 223 oder der EP-B-0 705 549 bekannt.Similar seat cushions are from the US-A-5,634,223 or the EP-B-0 705 549 known.

Nachteilig bei den bekannten, im wesentlichen kreisrunden Sitzkissen ist es, daß diese für einen Benützer des Sitzkissens beim Sitzen auf diesem eine nur ungenügende Auflage insbesondere für die Oberschenkel des Benützers haben, wenn sie nicht einen entsprechend großen Durchmesser haben und bis in den Bereich der Oberschenkel eines Benützers ragen.A disadvantage of the known, substantially circular seat cushion is that they have for a user of the seat cushion when sitting on this one insufficient support especially for the thighs of the user, if they do not have a correspondingly large diameter and into the region of the thigh of a user protrude.

Der Erfindung liegt die Aufgabe zugrunde, ein Sitzkissen vorzusehen, das diesen Nachteil nicht besitzt.The invention has for its object to provide a seat cushion that does not have this disadvantage.

Gelöst wird diese Aufgabe erfindungsgemäß mit einem Sitzkissen, das die Merkmale des Anspruches 1 aufweist.This object is achieved according to the invention with a seat cushion, which has the features of claim 1.

Bevorzugte und vorteilhafte Ausgestaltungen des erfindungsgemäßen Sitzkissens sind Gegenstand der Unteransprüche.Preferred and advantageous embodiments of the seat cushion according to the invention are the subject of the dependent claims.

Durch die Maßnahme, den Übergangswandbereich in zwei Bereichen mit größerem Abstand von der Mitte des Sitzkissens auszubilden, werden "ohrartige" Vorsprünge des Sitzkissens gebildet, die als Auflagen für Oberschenkel einer Person, die auf dem Sitzkissen sitzt, dienen können. Das erfindungsgemäße Sitzkissen bietet demnach auch dann Auflagebereiche für Oberschenkel eines Benutzers, wenn das Sitzkissen im übrigen mit einem Durchmesser ausgebildet ist, der für das Gesäß eines Benutzers eine gerade ausreichend große Sitzfläche bietet.By the measure of forming the transitional wall area in two areas with a greater distance from the center of the seat cushion, "ear-like" protrusions of the seat cushion are formed, which can serve as supports for thighs of a person sitting on the seat cushion. The seat cushion according to the invention therefore also provides support areas for thighs of a user, when the seat cushion is otherwise formed with a diameter that provides a just enough large seat for the buttocks of a user.

Weitere Einzelheiten, Merkmale und Vorteile des erfindungsgemäßen Sitzkissens ergeben sich aus der nachstehenden Beschreibung bevorzugter Ausführungsbeispiele anhand der Zeichnungen.Further details, features and advantages of the seat cushion according to the invention will become apparent from the following description of preferred embodiments with reference to the drawings.

Es zeigt:

  • Fig. 2a das Sitzkissen in Draufsicht;
  • Fig. 2b das Sitzkissen in Seitenansicht und von unten der Fig. 2a aus gesehen;
  • Fig. 3a das Sitzkissen in Draufsicht; und
  • Fig. 3b das Sitzkissen in Seitenansicht von unten der Fig. 3a aus gesehen; und
  • Fig. 4 das Sitzkissen von der Seite gesehen mit einer auf diesem sitzenden Person, wobei die Ausrichtung des Sitzkissens durch die in Fig. 4 eingezeichnete Draufsicht dargestellt ist.
It shows:
  • Fig. 1 an inventive seat cushion in side view;
  • Fig. 2a the seat cushion in plan view;
  • Fig. 2b the seat cushion in side view and from below the Fig. 2a seen from;
  • Fig. 3a the seat cushion in plan view; and
  • Fig. 3b the seat cushion in side view from below the Fig. 3a seen from; and
  • Fig. 4 the seat cushion seen from the side with a person sitting on this, the orientation of the seat cushion by the in Fig. 4 drawn top view is shown.

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.A seat cushion 1 according to the invention, as shown in the exemplary embodiment, preferably consists of a flexible material, in particular a flexible plastic film, which is e.g. has rubber-elastic 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 seat surface wall portion 3 which is substantially circular, a substantially equal, also circular bottom surface wall portion 5 and a transition wall portion 7. The transition wall portion 7 connects the seat surface wall portion 3 with the bottom surface wall portion 5 to form a bead, the preferably 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 may be formed on its outside with wavy ornamental and / or reinforcing lines 9, for example in the form of projecting ribs.

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.Also, it is shown that when the seat cushion 1 is unloaded, the seat surface wall portion 3 and the bottom surface wall portion 5 are convex, and the convexity of the seat surface wall portion 3 is larger than that of the bottom surface wall portion 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 in den Auflagen bildenden Bereichen 11 für Oberschenkel 13 einer auf dem Sitzkissen 1 sitzenden Person 17 weitestgehend kreisbogenförmig (symbolisiert durch eingezeichnete Kreise).As in particular the Fig. 2a and 3a can be seen, has the Seat cushion according to the invention two areas 11, which serve as supports for thighs 13, in particular in their adjacent to the buttocks 15 of a user 17 sections. The regions 11 are formed primarily by the transition wall region 7, which has a greater distance there from the center 19 of the seat cushion 1. As the Fig. 2b and 3b show, the outer shape 21 of the transition wall portion 7 in the pads forming portions 11 for thighs 13 of a seated on the seat cushion 1 person 17 largely circular arc-shaped (symbolized by drawn circles).

Dabei ist es so, daß die beiden Auflagen bildenden 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 pads forming areas 11 have a distance. The distance of the transition wall portion 7 from the center 19 of the seat cushion 1 increases in the region of the pads forming areas 11 to the center plane 23 of each area 11, this increase in the distance may be continuous.

Der Bodenflächenwandbereich 5 des erfindungsgemäßen Sitzkissens 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 portion 5 of the seat cushion 1 according to the invention is arranged at unloaded seat cushion 1, so if no person 17 sits on this, compared to the deepest portion of the bead formed by the transition wall portion 7 inside, so offset from the horizontal center plane of the seat cushion 1 out. This is shown in particular by the Fig. 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 oriented so that the ear-shaped pad forming portions 11 are disposed below the thighs 13 of a user 17, as shown in Figs Fig. 4 is shown symbolically.

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 portion 25 and the edge bead, which is formed by the transition wall portion 7 are formed in the areas 11 substantially (moon) sickle-shaped and with unloaded seat cushion 1 is substantially flat. As a result, good conditions for the thighs 13 of a person 17 seated on the seat cushion 17 are formed, in particular following the seat surface wall region 3.

Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt dargestellt werden:

  • 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 bildenden Bereiche 11 abgestützt sind, wie dies sonst nur bei einem Sitzkissen mit insgesamt größerem Durchmesser gegeben wäre.
In summary, an embodiment of the invention can be represented as follows:
  • A seat cushion 1 having a seat surface wall portion 3 and a bottom surface wall portion 5 has a bead-shaped transition wall portion 7 connecting the seat surface wall portion 3 with the bottom surface wall portion 5. Thus, there is a fluid-tight pad 1, which can be filled with air via a closable filling opening. In two spaced-apart regions 11, the distance of the transition wall portion 7 from the center 19 of the seat cushion 1 is increased, whereby in plan view lenticular, on the otherwise determined by the transition wall portion 7, substantially circular contour shape of the seat cushion 1 laterally projecting portions 11 are formed. These protruding areas 11 are supports for thighs 17 of a person sitting on the seat cushion 1 person 17. This results in a good seating comfort even with a small diameter of the generally circular seat cushion 1, since the thighs 13 at least in the adjoining the buttocks 15 area by the projecting, Supports forming areas 11 are supported, as would otherwise be given only in a seat cushion with a larger overall diameter.
