Abstract

The sitting surface of a seat for motor vehicles consists of the basic seat (1a) side bulges (1b) and side ends (1c). The parts (1) laid in the foaming mould for backfilling with PU foam (4) can be made of cloth, plastics or leather. A perspiration mat (2) and a PU foil (3) cover the (1a) area, and a lining (8) the (1b) area. Textile strips (6a,6b,6c) through which the PU foam can penetrate, are sewn in by quilted seams (5a,5b,7) to add to the stability of the foam structure. ADVANTAGE - This creates a vehicle seat with a functionally better design.

Description

Die Erfindung betrifft einen Sitz, insbesondere einen Fahrzeugsitz, mit einem hinterschäumten Bezug, sowie zumindest einem an diesen angreifenden Halteelement. Ein derartiger Sitz ist aus der gattungsbildenden DE-OS 23 57 491 bekannt.The invention relates to a seat, in particular a Vehicle seat, with a foam-backed cover, as well at least one holding element engaging on this. A such seat is from the generic DE-OS 23 57 491 known.

Zur Herstellung von Fahrzeugsitzen wird ein entsprechend vorgefertigter Sitzbezug in ein Hinterschäumwerkzeug eingelegt, wonach die Bezughülle mit einem geeigneten Kunststoff-Schaummaterial, zumeist einem Polyurethan­ schaum, ausgefüllt wird. Oftmals wird die Schaumstruktur dabei durch eingelegte Metalldrähte verstärkt. Bekannt sind darüber hinaus auch Sitzausführungen - so bei­ spielsweise aus der oben genannten Schrift -, bei denen der Bezug durch geeignete Halteelemente bezüglich der Schaumstruktur fixiert ist. Eine andere Ausführungsform für ein derartiges Sitzkissen zeigt beispielsweise die DE-PS 29 21 740.A corresponding is used to manufacture vehicle seats prefabricated seat cover in a rear foam tool inserted, after which the cover with a suitable Plastic foam material, mostly a polyurethane foam that is filled. Often the foam structure reinforced by inserted metal wires. Known are also seat designs - so at for example from the above-mentioned script - in which the reference by means of suitable holding elements with respect to the Foam structure is fixed. Another embodiment for such a seat cushion shows, for example DE-PS 29 21 740.

Da die bislang bekannten Halteelemente entweder äußerst aufwendig gestaltet sind oder den Sitzkomfort bzw. die Haltbarkeit des Sitzbezuges herabsetzen, hat sich die Erfindung zur Aufgabe gestellt, einen hinsichtlich seiner Funktionalität verbesserten Sitz aufzuzeigen. Since the previously known holding elements are either extremely are elaborately designed or the seating comfort or The durability of the seat cover has decreased Invention set for a task to show its functionality improved fit.  

Zur Lösung dieser Aufgabe ist vorgesehen, daß das Halteelement als ein durch das Hinterschäumen in die Schaumstruktur eingebundener Textilstreifen ausgebildet ist. Unter den Begriff des Textilstreifens fallen dabei sämtliche Strukturen, die in der Lage sind, während des Hinterschäumvorganges Anteile des sie umgebenden Schaum­ materiales aufzusaugen. Anstelle von Textilgeweben können auch Vliese, Gaze- oder Lederstreifen oder dgl. zum Einsatz kommen. Unter Beibehaltung einer gewünschten Elastizität wird unter Schonung des Sitzbezuges dessen Lage bezüglich des Schaumkernes festgelegt, da der sog. Textilstreifen unter Wahrung einer ausreichenden Flexi­ bilität in die Schaumstruktur eingebunden ist. Vorteil­ hafterweise verleiht ein derartiger, in seiner Länge den jeweiligen Anforderungen entsprechend gestalteter Textilstreifen der Schaumstruktur auch eine zusätzliche Steifigkeit, so daß die bislang üblichen Drahteinlagen in der Schaumstruktur ersatzlos entfallen können.To solve this problem it is provided that Holding element as one by foaming into the back Foam structure integrated textile strips is. The term textile stripes is used here all structures that are able to Back-foaming process proportions of the foam surrounding them absorb material. Instead of textile fabrics can also fleece, gauze or leather strips or the like. are used. While maintaining a desired one Elasticity is preserved while protecting the seat cover Position determined with respect to the foam core, since the so-called. Textile strips while maintaining sufficient flexi is integrated into the foam structure. Advantage such a lends, in its length, the designed according to the respective requirements Textile strips of the foam structure also an additional Stiffness, so that the usual wire inlays can be omitted without replacement in the foam structure.

Vorteilhafte Aus- und Weiterbildungen der Erfindung beschreiben die Unteransprüche. So kann in Analogie zur gattungsbildenden Schrift der Textilstreifen in ein­ facher Weise in eine zwei Bezugsteile miteinander verbindende Naht eingebunden, so beispielsweise einge­ näht oder eingeschweißt sein. Insbesondere für Bezugs­ teile aus Leder übernimmt hier der in die Naht einge­ bundene Textilstreifen eine zusätzliche Dichtfunktion. Eine andere einfache Möglichkeit, den Textilstreifen festzulegen bzw. zu positionieren besteht darin, ihn gemäß Anspruch 3 in ohnehin vorhandene Stepp- oder Ziernähte einzuhängen bzw. einzubinden.Advantageous developments and further developments of the invention describe the subclaims. In analogy to generic writing of the textile strips in one in two ways with each other connecting seam integrated, such as inserted sewn or welded. Especially for reference Leather parts are incorporated into the seam here tied textile strips an additional sealing function. Another easy way to use the textile strip To define or position it is to set it according to claim 3 in any existing quilting or Hook in or tie in decorative seams.

Insbesondere in Fällen, in denen der in die Schaum­ struktur eingebundene Textilstreifen auch dazu dient, Drahteinlagen in der Schaumstruktur ersatzlos entfallen zu lassen, kann es sich empfehlen, insbesondere ein Bezugs-Seitenteil des Sitzes auf der dem Schaum zuge­ wandten Seite nicht zu kaschieren. Alternativ kann eine schaumaufnahmefähige Kaschierung vorgesehen sein. Hierdurch dringen Schaumpartikel in dieses Bezugs-Sei­ tenteil ein, erhöhen dessen Steifigkeit und verbinden dieses in gewisser Weise mit der Schaumstruktur.Especially in cases where the in the foam structure-integrated textile strips also serves No wire inserts in the foam structure are required it may be advisable to leave, especially one  Cover side part of the seat on the foam facing side not to hide. Alternatively, one Foam-absorbent lamination may be provided. As a result, foam particles penetrate this reference screen part, increase its rigidity and connect this in a way with the foam structure.

Der in einer Prinzipskizze gezeigte partielle Schnitt durch ein Sitzkissen dient als bevorzugtes Ausführungs­ beispiel der näheren Erläuterung der Erfindung.The partial section shown in a schematic diagram by a seat cushion serves as the preferred version example of a more detailed explanation of the invention.

Ein Fahrzeugsitz weist mehrere den einzelnen Sitzbe­ reichen zugeordnete Bezugsteile 1a, 1b, 1c auf. Das Bezugsteil 1a findet sich im Sitz-Hauptbereich und bildet die eigentliche Sitzfläche, das Bezugsteil 1b verkleidet einen seitlichen Sitzwulst und das Bezugsteil 1c schließlich schließt ein Sitz-Seitenteil ab. Unter dem Bezugsteil 1a befindet sich eine Schweißmatte 2, die mit einer TPU-Folie 3 abgeschlossen ist. Der Bereich unterhalb der einzelnen Bezugsteile 1 bzw. der Schweiß­ matte 2 ist mit PU-Schaum 4 hinterschäumt.A vehicle seat has a plurality of reference parts 1 a, 1 b, 1 c assigned to the individual seat areas. The cover part 1 a is found in the main seat area and forms the actual seat, the cover part 1 b covers a side seat bead and the cover part 1 c finally closes a seat side part. Under the cover part 1 a there is a welding mat 2 , which is finished with a TPU film 3 . The area below the individual reference parts 1 or the welding mat 2 is back-foamed with PU foam 4 .

Das Bezugsteil 1a ist mit dem Bezugsteil 1b in einer Naht 5a und letztgenanntes Bezugsteil mit dem Bezugsteil 1c in einer Naht 5b verbunden. In diese Nähte sind wie gezeigt Textilstreifen 6a, 6b eingebunden. Ein ähnlicher Textilstreifen 6c ist in einer die Schweißmatte 2 bezüglich des Bezugsteiles la fixierenden Steppnaht 7 eingehängt. Während des Hinterschäumvorganges dringen dabei Teile des PU-Schaumes 4 in die Textilstreifen 6 ein, so daß zum einen die einzelnen Bezugsteile in Relation zur PU-Schaumstruktur 4 fixiert sind, sowie zum anderen der Schaumstruktur 4 eine zusätzliche Stabilität verliehen wird. The reference part 1 a is connected to the reference part 1 b in a seam 5 a and the latter reference part to the reference part 1 c in a seam 5 b. As shown, textile strips 6 a, 6 b are integrated into these seams. A similar textile strip 6 c is suspended in a stitching 7 which fixes the welding mat 2 with respect to the reference part 1 a. During the back-foaming process, parts of the PU foam 4 penetrate into the textile strips 6 , so that on the one hand the individual reference parts are fixed in relation to the PU foam structure 4 , and on the other hand the foam structure 4 is given additional stability.

Während das Bezugsteil 1b auf seiner der Schaumstruktur 4 zugewandten Seite mit einer Kaschierschicht 8 versehen ist, fehlt eine derartige Kaschierung am Seiten-Bezugs­ teil 1c. Da hierdurch Teile des PU-Schaumes 4 auch in das Bezugsteil 1c eindringen können, gewinnt der ge­ zeigte Sitz weiter an Seitenstabilität.While the reference part 1 b is provided on its side facing the foam structure 4 with a lamination layer 8 , such a lamination is missing on the side reference part 1 c. Since this allows parts of the PU foam 4 to penetrate into the reference part 1 c, the seat shown continues to gain lateral stability.

Die Bezugsteile 1 selbst können in unterschiedlichsten Materialien ausgebildet sein, so beispielsweise in Stoff, Kunststoff oder Leder. Für den sog. Textilstrei­ fen hingegen sollte ein Material zum Einsatz kommen, das zu durchdringen der PU-Schaum in der Lage ist.The reference parts 1 themselves can be formed in a wide variety of materials, for example in fabric, plastic or leather. For the so-called textile strip, however, a material should be used that is able to penetrate the PU foam.
