The profile strip is embedded along an outer surface thereof in a foam cushion member forming the padding and is surrounded by a tightened cover.

Description

Die Erfindung betrifft ein Sitzmöbel mit an einer Tragschale angebrachter Polsterung, welche aus einem Schaumstoffpolsterkörper, einem Bezug und einem Keder zur Einspannung des Bezuges am Schalenrand besteht, wobei der Keder und der Schalenrand als zugehörige, den Bezug zwischen sich einspannende Teile einer Klemmverbindung ausgebildet sind.The invention relates to a piece of seating furniture with upholstery attached to a carrying shell, which consists of a foam cushion body, a cover and a piping for clamping the cover on the edge of the shell, the piping and the edge of the shell being designed as associated parts of a clamp connection which clamp the cover between them.

Bei den bekannten derartigen Tragschalen für das Sitz- und ggf. 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 upholstery, 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, i.e. generally clamped together using a U-shaped strip. However, the assembly work to be carried out here is 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.

Durch die CH-A-526 289 ist ein Sitzmöbel aus Tragschale, Schaumstoffpolsterkörper und Bezug bekannt, bei dem die Ränder des mit Kantenversteifungen versehenen Bezuges in Nuten der Tragschale eingesteckt werden. Diese Befestigungsart verlangt aber den Einsatz von Hilfsvorrichtungen, um den Bezug mit der erforderlichen Spannung aufziehen zu können, und es sind dort noch besondere Spannbügel vorgesehen, um die Spannung des Bezuges bis zur Endmontage des Sitzmöbels aufrecht zu erhalten.CH-A-526 289 discloses a piece of seating furniture comprising a carrier shell, foam cushion body and cover, in which the edges of the cover provided with edge reinforcements are inserted into grooves in the carrier shell. However, this type of fastening requires the use of auxiliary devices in order to be able to open the cover with the required tension, and special tensioning brackets are also provided there in order to maintain the tension of the cover until final assembly of the seating furniture.

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 with 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 und der Schaumstoffpolsterkörper eine vorgefertigte Baueinheit sind und dass der Keder an seinen Aussenflächen in den Schaumstoffpolsterkörper eingebettet und an seiner den Schaumstoffpolsterkörper abgewandten Seite vom Bezug umspannt ist.According to the invention, this is achieved in that the piping and the foam cushion body are a prefabricated structural unit and that the piping is embedded in the foam cushion body on its outer surfaces and is spanned by the cover on its side facing away from the foam cushion body.

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 aufeinandergesetzt werden können, wobei vorteilhafterweise nunmehr der Bezug mit einer gew sen Nachgiebigkeit um den Schaumstoffpolsterki per und Keder insgesamt herumgeschlagen werd kann. Beim nachfolgenden Aufdrücken des Kede auf den Schalenrand erfährt der Bezug allseitig eii 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 pad body now holds the integrated piping in the correct orientation on the shell edge during assembly, so that the parts to be plugged together along their entire plug edge can be placed on one another at a time, advantageously now the cover with a certain amount of flexibility around the foam pad and per piping as a whole can be beaten around. When the kede is subsequently pressed onto the edge of the shell, the cover is tensioned on all sides.

Die Erfindung erlaubt es somit dem Hersteller, B zug, Schaumstoffpolsterkörper und Keder als qua einstückiges Ersatzteil zu liefern, das beim Au wechseln lediglich auf die Tragschale aufzuklipsE ist.The invention thus allows the manufacturer to supply the train, foam cushion body and piping as a one-piece spare part which can only be clipped on to the carrier shell when changing.

In weiterer Ausgestaltung der Erfindung kann vo gesehen werden, dass der Schalenrand wulst-, : oder T-förmig profilliert ist und dass der Keder eir dem Schalenrandprofil eng angepasste Nut zur Eil spannung des Bezuges besitzt.In a further embodiment of the invention it can be seen that the shell edge is profiled in a bead, or T shape and that the piping has a groove which is closely matched to the shell edge profile for the rapid tensioning of the cover.

Zweckmässigerweise weist das Profil des Kede ein oder zwei zusätzliche, hinterschnittene Nute auf, welche mit Schaumstoff des Poisterkörpei ausgefüllt sind. Durch diese Profilierung wird eine be sonders feste Einbettung des Keders im Schaun stoffkörper gewährleistet. Der Keder kann hierbei ir Polsterkörper fest eingeschäumt sein, wobei der ir allgemeinen ebenfalls aus Kunststoff bestehend Keder vom frischen Schaum angelöst wird und sic mit diesem innig und fest verbindet. Alternativ kan der Schaumstoffpolsterkörper auch mit einem Aui nahmeprofil für den Keder hergestellt werden un der Keder durch Ankleben oder Anklammern in die sem Aufnahmeprofil fest untergebracht werden.The profile of the kede expediently has one or two additional, undercut grooves which are filled with foam of the poister body. This profiling ensures a particularly firm embedding of the piping in the fabric body. The piping can be firmly foamed into the upholstery body, the piping, which is generally also made of plastic, being detached from the fresh foam and connecting it intimately and firmly with it. Alternatively, the foam upholstery body can also be produced with an attachment profile for the piping and the piping can be firmly accommodated in this mounting profile by gluing or clipping.
