Description

Die Erfindung betrifft ein Sitzmöbel mit an einer Tragschale angebrachter Polsterung, welche aus einem Schaumstoffpolsterkörper, einem Bezug und einem Keder zur Einspannung des Be - zuges am Schalenrand besteht.The invention relates to a piece of seating furniture with padding attached to a carrier shell, which consists of a foam cushion body, a cover and a piping for clamping the cover on the edge of the shell.

Bei den bekannten derartigen Tragschalen für das Sitz- und ggfs. auch Lehnenpolster aufweisenden Sitzmöbeln wird der Schaumstoffpolsterkörper auf die Tragschale aufgelegt, danach der Bezug über den Polsterkörper und den Tragschalenrand herumgezogen, wonach der Bezug zusammen mit dem Schalenrand mittels eines umlaufenden Keders, d. h. im allgemeinen mittels eines U-Profilstreifens, zusammengeklemmt werden. Die dabei auszuführenden Montagearbeiten sind jedoch verhältnismäßig kompliziert und im allgemeinen nur von der Herstellfirma bzw. einem Polsterer ausführbar. Bei einer Beschädigung des Bezuges, des Schaumstoffkörpers oder auch nur des Keders ist der Kunde im allgemeinen nicht mehr in der Lage, die Polsterung auszuwechseln, selbst wenn ihm die Teile einer neuen Polsterung von der Herstellfirma zur Verfügung gestellt werden.In the known supporting shells of this type for the seating and possibly also backrest cushions, the foam cushion body is placed on the supporting shell, then the cover is pulled over the cushion body and the supporting shell edge, after which the covering together with the edge of the shell by means of a circumferential welt, ie in general can be clamped together using a U-profile strip. The assembly work to be carried out is ver relatively complicated and can generally only be carried out by the manufacturer or an upholsterer. If the cover, the foam body or even the welt is damaged, the customer is generally no longer able to replace the upholstery, even if the parts of a new upholstery are made available by the manufacturer.

Der Erfindung liegt die Aufgabe zugrunde, die Polsterung des gattungsgemäßen Sitzmöbels derart zu gestalten, daß diese mit wenigen einfachen Handgriffen montiert und später auch vom Käufer nach Beschaffung eines entsprechenden Ersatzteiles ausgewechselt werden kann.The invention has for its object to design the upholstery of the generic seating furniture in such a way that it can be assembled in a few simple steps and later replaced by the buyer after procuring a corresponding spare part.

Dies wird der Erfindung zufolge dadurch erreicht, daß der Keder an seinen Außenflächen im Schaumstoffpolsterkörper eingebettet und vom Bezug umspannt ist.This is achieved according to the invention in that the piping is embedded on its outer surfaces in the foam cushion body and is covered by the cover.

Gerade die Einbettung des Keders in den Schaumstoffpolsterkörper erbringt entscheidende Vorteile im Hinblick auf die Montage bzw. Auswechselbarkeit der Polsterung. Zunächst verringert sich durch diese Einbettung die Anzahl der miteinander noch montagemäßig zu verbindenden Teile von früher vier auf nunmehr drei, nämlich Bezug, Schaumstoffpolster-Keder-Körper und Schale. Weiterhin hält der Schaumstoffpolsterkörper bei der Montage den integrierten Keder nunmehr in korrekter Ausrichtung auf den Schalenrand, so daß die zusammenzusteckenden Teile längs ihres gesamten Steckrandes auf einmal aufeinander gesetzt werden können, wobei vorteilhafterweise nunmehr der Bezug mit einer gewissen Nachgiebigkeit um den Schaumstoffpolsterkörper und Keder insgesamt herumgeschlagen werden kann. Beim nachfolgenden Aufdrücken des Keders auf den Schalenrand erfährt der Bezug allseitig eine definierte Nachspannung.The embedding of the piping in the foam cushion body provides decisive advantages with regard to the assembly or interchangeability of the upholstery. First of all, this embedding reduces the number of parts still to be connected to one another in terms of assembly from the previous four to now three, namely the cover, the foam padded piping body and the shell. Furthermore, the foam cushion body now holds the integrated piping during assembly more in the correct orientation on the edge of the shell, so that the parts to be put together can be placed on one another along their entire plug-in edge, the cover now advantageously being able to be turned around with a certain flexibility around the foam cushion body and piping. When the piping is subsequently pressed onto the edge of the shell, the cover experiences a defined re-tension on all sides.

Die Erfindung erlaubt es somit dem Hersteller, Bezug, Schaumstoffpolsterkörper und Keder als quasi einstückiges Ersatzteil zu liefern, das beim Auswechseln lediglich auf die Tragschale aufzuklipsen ist.The invention thus allows the manufacturer to supply the cover, foam cushion body and piping as a quasi-one-piece spare part that can only be clipped onto the carrier shell when being replaced.

In weiterer Ausgestaltung der Erfindung kann vorgesehen werden, daß der Schalenrand wulst-, Z- oder T-förmig profiliert ist und daß der Keder eine dem Schalenrandprofil eng angepaßte Nut zur Einspannung des Bezuges besitzt.In a further embodiment of the invention it can be provided that the edge of the shell is profiled in a bead, Z or T shape and that the piping has a groove which is closely matched to the edge of the shell for clamping the cover.

Zweckmäßigerweise weist das Profil des Keders ein oder zwei zusätzliche, hinterschnittene Nuten auf, welche mit Schaumstoff des Polsterkörpers ausgefüllt sind. Durch diese Profilierung wird eine besonders feste Einbettung des Keders im Schaumstoffkörper gewährleistet. Der Keder kann hierbei im Polsterkörper fest eingeschäumt sein, wobei der im allgemeinen ebenfalls aus Kunststoff bestehende Keder vom frischen Schaum angelöst wird und sich mit diesem innig und fest verbindet. Alternativ kann der Schaumstoffpolsterkörper auch mit einem Aufnahmeprofil für den Keder hergestellt werden und der Keder durch Ankleben oder Anklammern in diesem Aufnahmeprofil fest untergebracht werden.The profile of the piping expediently has one or two additional, undercut grooves which are filled with foam of the upholstery body. This profiling ensures a particularly firm embedding of the welt in the foam body. The piping can be firmly foamed in the upholstery body, the piping generally also made of plastic fresh foam is dissolved and combines with it intimately and firmly. Alternatively, the foam cushion body can also be produced with a mounting profile for the piping and the piping can be firmly accommodated in this mounting profile by gluing or clipping.

Der Gegenstand der Erfindung wird im folgenden anhand der Zeichnung näher erläutert, in der zeigen :

  • Figur 1 einen Querschnitt durch den Sitzteil eines Sitzmöbels,
  • Fig. 2 in vergrößerter Darstellung den Randbereich der gepolsterten Sitzfläche,
  • Figur 3 im Querschnitt den Keder nach Fig. 2,
  • Figur 4 eine abgewandelte Ausführungsform des Keders und
  • Figur 5 eine für eine Auswechslung bestimmte Sitzflächenpolsterung nach der Erfindung.
The object of the invention is explained in more detail below with reference to the drawing, in which:
  • FIG. 1 shows a cross section through the seat part of a piece of seating furniture,
  • 2 is an enlarged view of the edge area of the padded seat,
  • FIG. 3 shows the piping according to FIG. 2 in cross section,
  • Figure 4 shows a modified embodiment of the welt and
  • Figure 5 is intended for a replacement seat padding according to the invention.

Das nur im Detail dargestellte Sitzmöbel besitzt eine von einem Standbein 1 gehaltene Sitzschale 2, deren Rand nach oben und dann nach außen hin Z-förmig abgekröpft ist. Der nach außen hin abgekröpfte Randschenkel 3 des umlaufenden,, Z-förmig profilierten Schalenrandes 4 ist nach außen hin keilförmig verdickt. Auf der Sitzschale 2 liegt ein Schaumstoffpolsterkörper 5, in welchen ein ringsum laufender Keder 6 eingebettet ist. Der Keder besitzt etwa C-Profil und ist unter Zwischeneinspannung eines Bezuges 7 ringsum auf den Schalenrand 4 aufgesteckt, wobei der Bezug mehrfach scharfkantig bzw. rechtwinklig zwischen den eng aneinander angepaßten C- und Z-Profilen der beiden Steckteile abgeknickt ist.The seating furniture shown only in detail has a seat shell 2 held by a supporting leg 1, the edge of which is bent in a Z-shape upwards and then outwards. The outwardly bent edge leg 3 of the circumferential ,, Z-shaped profiled shell edge 4 is thickened towards the outside in a wedge shape. On the seat shell 2 is a foam cushion body 5, in which an all-round welt 6 is embedded. The piping has about a C-profile and is placed around the shell edge 4 with the interposition of a cover 7, the cover being bent several times at right angles or at right angles between the closely matched C and Z profiles of the two plug-in parts.

Der Keder 6 ist beim Ausführungsbeispiel nach Fig. 2 an seiner gesamten Außenfläche, d. h. mit Ausnahme seiner Innennut, mit Schaumstoff umschäumt, wodurch ein fester Zusammenhalt zwischen Keder und Schaumstoffpolsterkörper 5 gewährleistet ist.The piping 6 is in the embodiment of FIG. 2 on its entire outer surface, ie. H. with the exception of its inner groove, foamed with foam, which ensures firm cohesion between the piping and foam pad body 5.

Beim Ausführungsbeispiel nach Fig. 4 ist ein etwa H-förmig profilierter Keder 8 vorgesehen, der außer der hinterschnittenen Aufnahmenut zur Aufnahme des Z-förmigen Schalenrandes 4 noch weitere hinterschnittene, mit Schaumstoff ausgefüllte Nuten 9, 10 aufweist.In the exemplary embodiment according to FIG. 4, an approximately H-shaped profiled piping 8 is provided which, in addition to the undercut receiving groove for receiving the Z-shaped shell edge 4, has further undercut grooves 9, 10 filled with foam.

Fig. 5 veranschaulicht die Auswechselbarkeit der Polsterung nach der Erfindung. Als Austauschteil ist hier fabrikmäßig der Schaumstoffpolsterkörper 5 mit eingebettetem Keder 6 integriert. Dieser Bauteil 5/6 kann ebenfalls bereits vom Hersteller mit dem gewünschten Bezug 7 überspannt sein, wobei einige elastische Schnüre 11, Kordeln od. dgl., den Bezug an der Unterseite provisorisch zusammenhalten. Dieses Ersatzteil wird längs des Keders 6 auf den Rand 4 der Schale aufgesetzt und dann schnappend aufgedrückt, wobei der Bezug 7 durch das Eindrücken in die Kedernut 12 eine definierte Nachspannung erfährt.Fig. 5 illustrates the interchangeability of the padding according to the invention. As a replacement part, the foam cushion body 5 with embedded piping 6 is integrated here in the factory. This component 5/6 can also be from Manufacturer with the desired cover 7 to be spanned, with some elastic cords 11, cords or the like, temporarily holding the cover together on the underside. This spare part is placed along the welt 6 on the edge 4 of the shell and then snapped open, the cover 7 being subjected to a defined retensioning by pressing into the welt groove 12.

Anstelle einer provisorischen Halterung durch die Schnüre 11 oder dgl. kann der Bezug auch schon endgültig am Bauteil 5/6 festgespannt sein, indem man beispielsweise einen Keder mit im Inneren angeordneter Fanglippe verwendet, die den hineingedrückten Bezug gegen ein Wiederherausrutschen sichert.Instead of a provisional mounting by means of the cords 11 or the like, the cover can also be permanently clamped to the component 5/6, for example by using a piping with a catch lip arranged on the inside, which secures the pressed-in cover against slipping out again.
