Description

2 AT 502 178 B12 AT 502 178 B1

Die Erfindung betrifft ein System zur automatischen Verstellung der Kontur eines Fahrzeugsitzes, wobei zumindest eine fluidbefüllbare und damit volumsveränderbare Blase vorgesehen und an einem der Sitzkontur angepassten oder anpassbaren, aus einem Gewebe, Gelege oder Gewirke hergestellten Träger für Zusatzbauteile unterhalb der Oberfläche des Sitzes befestigt 5 ist, sowie ein Verfahren zur Herstellung eines System zur automatischen Verstellung der Kontur eines Fahrzeugsitzes, umfassend die Anbringung einer fluidbefüllbaren und damit volumsveränderbaren Blase auf einem der Sitzkontur angepassten oder anpassbaren, aus einem Gewebe, Gelege oder Gewirke hergestellten Träger für Zusatzbauteile. io Blasen oder Luftkissen für Systeme zur Sitzverstellung oder für Komfortfunktionen wie Lordosestützen oder Massagesysteme sind oftmals nicht unmittelbar an der Sitzstruktur angebracht, sondern auf separaten Trägern. Diese Träger sind meist Matten oder Zuschnitte aus Filz oder ähnlichen Geweben, Gelegen oder Gewirken. Auf diese Träger können die Blase oder auch andere für die gewünschte Funktionalität des Sitzes notwendige Zusatzbauteile mit Hilfe von 15 Klipsen oder Dornprofilen befestigt werden. Die Montage gestaltet sich dabei jedoch sehr aufwendig und muß meist sogar manuell durchgeführt werden. Nachteilig ist auch, daß zusätzliche Bauteile neben Luftkissen und Trägern erforderlich sind.The invention relates to a system for automatic adjustment of the contour of a vehicle seat, wherein at least one fluidbefüllbare and thus volume changeable bubble provided and attached to a seat contour adapted or customizable, made of a fabric, scrim or knitted support for additional components below the surface of the seat 5 is attached , and a method for producing a system for automatic adjustment of the contour of a vehicle seat, comprising the attachment of a fluid-fillable and thus variable-volume bladder on a seat contour adapted or customizable, made of a fabric, scrim or knitted support for additional components. Bubbles or airbags for seat adjustment systems or for comfort functions such as lumbar support or massage systems are often not directly attached to the seat structure, but rather on separate supports. These carriers are usually mats or blanks of felt or similar woven, laid or knitted fabrics. On this carrier, the bladder or other necessary for the desired functionality of the seat additional components with the aid of 15 clips or mandrel profiles can be attached. However, the assembly is very expensive and usually has to be done manually. Another disadvantage is that additional components in addition to air cushions and carriers are required.

Bei einer zweiten Variante für die Befestigung wird eine Lasche des Filzträgers durch die Folien 20 geschoben. Anschließend werden die zwei Folien so miteinander verschweißt, dass ein Formschluß zwischen Folie und Filz entsteht. Auch hier ist die Anfertigung mit Handarbeit verbunden und eine Automatisierung nur bedingt möglich.In a second variant for fastening a tab of the felt carrier is pushed through the films 20. Subsequently, the two films are welded together so that a positive connection between the film and felt is formed. Again, the production is associated with manual work and automation only partially possible.

Es war daher die Aufgabe der vorliegenden Erfindung, ein System der eingangs angegebenen 25 Art derart zu gestalten, daß es sowohl einfach und in möglichst wenigen Schritten zu fertigen ist, auch keine weiteren Bauteile benötigt werden und dennoch große Flexibilität in der Gestaltung sowie gute mechanische Eigenschaften gegeben sind. Weiters soll ein einfaches Verfahren zur Herstellung eines derartigen Systems mit größtmöglichem Automatisierungsgrad angegeben werden. 30It was therefore an object of the present invention to design a system of the type described above such that it is both simple and can be manufactured in as few steps as possible, no further components are needed and yet great flexibility in the design and good mechanical properties given are. Furthermore, a simple method for producing such a system with the greatest possible degree of automation should be specified. 30

Zur Lösung der ersten Aufgabe ist das System erfindungsgemäß dadurch gekennzeichnet, daß die Blase mit einem überstehenden verschweißbaren Materialabschnitt versehen ist, daß der Träger aus einem verschweißbaren Material angefertigt ist, und daß der überstehende Materialabschnitt der Blase mit dem Träger verschweißt ist. Damit ergibt sich ein sehr stabiles System 35 mit geringstmöglicher Anzahl an Bauteilen, welches für die einfache automatische Fertigung geeignet ist.To achieve the first object, the system according to the invention is characterized in that the bladder is provided with a protruding weldable material portion, that the carrier is made of a weldable material, and that the protruding material portion of the bladder is welded to the carrier. This results in a very stable system 35 with the lowest possible number of components, which is suitable for easy automatic production.

Gemäß einer ersten Ausführungsform des erfindungsgemäßen Systems ist vorgesehen, daß der überstehende Materialabschnitt der Blase zumindest teilweise durch den verschweißten 40 Bereich von die Blase bildenden Kunststoff-Folien gebildet ist. Damit ist mit geringem Mehraufwand für das Material zur Herstellung der Blasen, jedoch ohne Zusatzbauteile für deren Befestigung, ein sehr stabiles und für die einfache automatische Fertigung geeignetes System realisiert. 45 Um auch für beispielsweise Faltblasen die zuvor genannten Vorteile zu erreichen, ist die Erfindung gemäß einem weiteren Ausführungsbeispiel dadurch gekennzeichnet, daß für zwei durch zumindest einen verschweißten Verbindungsbereich verbundene Blasen bzw. kommunizierende Blasenvolumina der überstehende Materialabschnitt durch den Verbindungsbereich gebildet ist. Eine der Blasen muß dann lediglich über die andere Blase gefaltet werden, was ebenfalls so automatisch und mit geringem Aufwand erfolgen kann.According to a first embodiment of the system according to the invention it is provided that the protruding material portion of the bubble is at least partially formed by the welded portion 40 of the plastic sheets forming the bubble. This is realized with little additional effort for the material for the production of bubbles, but without additional components for their attachment, a very stable and suitable for easy automatic production system. In order to achieve the aforementioned advantages also for, for example, folding bladders, the invention according to a further embodiment is characterized in that, for two bladders or communicating bladder volumes connected by at least one welded connection area, the protruding material section is formed by the connection area. One of the bubbles must then be folded only over the other bubble, which can also be done so automatically and with little effort.

Vorteilhafterweise ist vorgesehen, daß der Träger aus Kunststoff-Fasern hergestellt ist, wobei ohne wesentliche Nachteile die Eigenschaften einfache Verschweißbarkeit, mechanische Festigkeit und lange Haltbarkeit verbunden sind. 55 3 AT 502 178 B1Advantageously, it is provided that the carrier is made of plastic fibers, which are connected without significant disadvantages, the properties of easy weldability, mechanical strength and durability. 55 3 AT 502 178 B1

Gemäß einer weiteren vorteilhaften Ausführungsform und unter Erzielung der oben genannten Vorteile können natürlich auch zusätzlich zur Blase weitere Bauteile mit dem Träger verschweißt sein. 5 Das eingangs beschriebene Verfahren zur Herstellung eines System zur automatischen Verstellung der Kontur eines Fahrzeugsitzes ist zur Lösung der gestellten Aufgabe erfindungsgemäß dadurch gekennzeichnet, daß die Blase mit einem überstehenden verschweißbaren Materialabschnitt versehen und dieser Materialabschnitt der Blase mit dem aus einem verschweißbaren Material angefertigten Träger verschweißt wird. 10 Für Blasenkonstruktionen, bei welchen die Blase durch Verschweißen zumindest zweier übereinanderliegender Kunststoff-Folien hergestellt wird, ist gemäß einer vorteilhaften Ausführungsform der Erfindung vorgesehen, daß das Verschweißen mit dem Träger in einem nachfolgenden Schritt durchgeführt wird. 15According to a further advantageous embodiment and while achieving the advantages mentioned above, of course, in addition to the bladder further components may be welded to the carrier. 5 The method described above for producing a system for automatic adjustment of the contour of a vehicle seat according to the invention to solve the problem is characterized in that the bladder provided with a protruding weldable material portion and this material portion of the bladder is welded to the made of a weldable material carrier , 10 For bladder designs in which the bladder is made by welding at least two superimposed plastic films, it is provided according to an advantageous embodiment of the invention that the welding is carried out with the carrier in a subsequent step. 15

Eine besonders rasche Herstellung ist bei einer Ausführungsform des Verfahrens zu erzielen, bei welcher gleichzeitig mit dem Verschweißen zumindest zweier übereinanderliegender Kunststoff-Folien zur Herstellung der Blase auch das Verschweißen mit dem Träger durchgeführt wird. 20A particularly rapid production is to be achieved in one embodiment of the method, in which simultaneously with the welding of at least two superimposed plastic films for the production of the bubble and the welding is carried out with the carrier. 20

Unter Vermeidung von zusätzlich notwendigen Bauteilen für die Befestigung der Blasen am Träger kann das Verfahren dadurch vereinfacht und optimal automatisiert werden, daß der überstehende Materialabschnitt aus zumindest einem Teil des verschweißten Randbereiches der Kunststoff-Folien ausgeformt wird. 25By avoiding additionally necessary components for the attachment of the bubbles to the carrier, the method can be simplified and optimally automated in that the projecting material portion is formed from at least part of the welded edge region of the plastic films. 25

Vorteilhafterweise können gemäß einer weiteren erfindungsgemäßen Ausführungsform der Verfahrens auch weitere Zusatzbauteile mit dem Träger verschweißt werden.Advantageously, according to a further embodiment of the method according to the invention, additional components can also be welded to the carrier.

In der nachstehenden Beschreibung soll die Erfindung anhand der beigefügten Zeichnungen an 30 einigen Ausführungsbeispielen erläutert werden.In the following description, the invention will be explained with reference to the accompanying drawings in some embodiments.

Dabei zeigt die Fig. 1 in Seitenansicht ein erfindungsgemäßes System zur Verstellung von Fahrzeugsitzen mittels luftbefüllbarer Blasen, Fig. 2 ist eine andere Ausführungsform eines derartigen Systems mit einer Doppelblase, Fig. 3a und 3b zeigen verschiedene Ausführungs-35 formen für die Verschweißung von Blasen und Trägermatte, Fig. 4a bis 4c zeigen Schnitte bzw. Seitenansichten von vorteilhaften Gestaltungen von Schweißwerkzeugen, und Fig. 5a und 5b ist eine Seitenansicht zweier unterschiedlicher Anordnungen bei der Herstellung des erfindungsgemäßen Systems. 40 Wie in Fig. 1 dargestellt ist, umfasst ein erfindungsgemäßes System zur automatischen Verstellung der Kontur eines Fahrzeugsitzes zumindest eine fluidbefüllbare und damit volumsveränderbare Blase 1, welche auf einem der Sitzkontur anpassbaren Träger 2 befestigt ist. Dieser Träger 2 besteht meist aus einem Kunststofffilz oder einem anderen Gewebe, Gelege oder Gewirke, und wird unterhalb der Oberfläche des Sitzes, d.h. des Sitzbezuges und allenfalls 45 auch unterhalb der Polsterung, befestigt. Weitere Zusatzbauteile wie etwa Federmatten 3, d.h. ein Drahtgeflecht unter dem Sitz, welches die Rückenpartie des Sitzes federnd unterstützt, eventuell ein Lüfter 4 für aktiv belüftete Sitze, oder auch Zusatzfilze 5, für eine optimale Befestigung des Filzträgers 2 auf der Federmatte 3, können vorgesehen sein. so Die Folienblase 1 wird mit zumindest einer überstehenden Lasche oder einem überstehendem Randbereich 1b mit dem Träger 2 verschweißt. Vorteilhafterweise ist diese Lasche 1b überstehendes Material der die Blase 1 bildenden Folien und kein separater Bauteil, der erst mit der Blase 1 verbunden werden müsste. Diese Lasche 1b aus überstehendem Folienmaterial wird direkt über vorzugsweise seine gesamte Breite bzw. Erstreckung, allenfalls auch nur in Teilbe-55 reichen davon, mit dem Träger 2 verschweißt. Auch alle Zusatzbauteile, wie etwa FedermattenFig. 2 is another embodiment of such a system with a double bubble, Fig. 3a and 3b show various embodiments for the welding of bubbles and Support mat, Figs. 4a to 4c show sections and side views of advantageous designs of welding tools, and Fig. 5a and 5b is a side view of two different arrangements in the manufacture of the system according to the invention. As shown in FIG. 1, a system according to the invention for the automatic adjustment of the contour of a vehicle seat comprises at least one bladder 1 which can be filled with fluid and thus variable in volume, which is fastened to a carrier 2 that can be adapted to the seat contour.

Claims (10)

4 AT 502 178 B1 3, Lüfter 4, Zusatzfilze 5 od. dgl. können in gleicher Weise und sogar gleichzeitig mit der Blase 1 in einem Verfahrensschritt am Träger 2 befestigt werden. Dabei können neben punkt- oder linienförmigen Schweißverbindungen auch wie in Fig. 3a dargestellt ringförmige Schweißverbindungen oder sich länglich erstreckende geschlossene Schweißverbindungen wie in Fig. 3b 5 vorgesehen sein, die je nach Bedarf für den zu befestigenden Bauteil bzw. entsprechend der Festigkeitsanforderungen gewählt werden können. In Fig. 2 ist die Verbindung einer zusammenhängenden Blase 1a auf dem Träger 1 dargestellt, wobei vorzugsweise die Verschweißung am Verbindungsbereich 1 b der beiden Blasenvolumina io vorgenommen wird. Um weiter dann beispielsweise eine Faltblase herzustellen, müssen die beiden Blasenvolumina lediglich übereinandergefaltet werden. Damit kann gegebenenfalls ein Arbeitsgang entfallen. Zum Einsatz kommen können verschiedene Arten von Schweißverfahren, beispielsweise Reib-15 schweißen, Ultraschallschweißverfahren oder bevorzugterweise Hochfrequenzschweißen. Letzteres Verfahren wird auch bei der Verschweißung von PU-Materialien verwendet. Somit können bei einer verketteten Anlage gleiche Verfahren Verwendung finden. Für aus miteinander entlang eines umlaufenden Randes verschweißten Kunststofffolien herge-20 stellte Blasen 1 werden meist diese Blasen 1 vor der Verbindung mit dem Träger 2 hergestellt. Erst in einem zweiten Arbeitsschritt wird dann der Träger 2 - oder werden auch Zusatzbauteile 3, 4, 5 mit den fertigen Blasen 1 verbunden. Jedoch ist auch die Herstellung der Blase 1 durch Verschweißung der Folien gleichzeitig mit der Verbindung mit dem Träger 2 in einem gemeinsamen Arbeitsgang möglich. 25 Um die Dauerfestigkeit des Systems zu verbessern, sind vorteilhafterweise die in den Fig. 4a bis 4c dargestellten Merkmale vorgesehen. Beim Schweißprozeß werden der Randbereich 1b der Blase 1 als auch das Material des Trägers 2 erwärmt. Das Werkzeug 7 verpreßt nach dem Aufschmelzprozeß beide Materialien miteinander. Um dabei an den Werkzeugkanten ausge-30 prägte Kanten der Schweißpunkte oder -linien zu vermeiden, welche die Dauerfestigkeit negativ beeinflussen können, sind vorteilhafterweise Abrundungen der Werkzeugkanten vorgesehen, wie für das gerade Werkzeug 7 der Fig. 4a oder das ringförmige Werkzeug 7b der Fig. 4c dargestellt. Auch eine Strukturierung der Werkzeugfläche des Werkzeuges 7a durch einfache, sich quer oder längs durch das Werkzeug ziehende Wellen, wie in Fig. 4b, wäre möglich. 35 In den Fig. 5a und 5b sind zwei verschiedene Anordnungen von Blase 1 und Trägermaterial 2 bei der Verschweißung in Seitenansicht dargestellt, wie sie speziell bei Verwendung von HF -Verfahren gewählt werden. Auf einem Schweißtisch 8 werden Träger 2, speziell aus Filz, und die Blase 1, speziell aus Kunststofffolie, aufgelegt. Eine oberes Werkzeug 7 in der Form der 40 zukünftigen Schweißnaht übernimmt dann die Verbindung der Bauteile 1, 2. Liegt die Blase 1 auf dem Träger 2 auf, dringt das obere Werkzeug 7 stark in das Folienmaterial der Blase 1 ein. Liegt hingegen der Filz des Trägers 2 auf der Blase 2, wird der Filz zur Blasenseite hin abgesenkt. Je nach Einsatzfall können durch diese Anordnungen unterschiedliche Eigenschaften erzielt werden. 45 Patentansprüche: 1. System zur automatischen Verstellung der Kontur eines Fahrzeugsitzes, wobei zumindest so eine fluidbefüllbare und damit volumsveränderbare Blase vorgesehen und an einem der Sitzkontur angepassten oder anpassbaren, aus einem Gewebe, Gelege oder Gewirke hergestellten Träger für Zusatzbauteile unterhalb der Oberfläche des Sitzes befestigt ist, dadurch gekennzeichnet, daß die Blase (1) mit einem überstehenden verschweißbaren Materialabschnitt (1b) versehen ist, daß der Träger (2) aus einem verschweißbaren Materi-55 al angefertigt ist, und daß der überstehende Materialabschnitt (1b) der Blase (1) mit dem 5 AT 502 178 B1 Träger (2) verschweißt ist.4 AT 502 178 B1 3, fan 4, additional felts 5 or the like can be attached to the support 2 in the same way and even simultaneously with the bladder 1 in one process step. In this case, in addition to point or line-shaped welded joints as shown in Fig. 3a annular welds or longitudinally extending closed welds as shown in Fig. 3b 5 may be provided, which can be selected as needed for the component to be fastened or according to the strength requirements. In Fig. 2, the connection of a contiguous bubble 1a is shown on the support 1, wherein preferably the welding at the connection portion 1 b of the two bladder volumes io is made. In order to further produce, for example, a folding bladder, the two bladder volumes merely have to be folded over one another. This may possibly account for one operation. Various types of welding processes can be used, for example friction welding, ultrasonic welding or, preferably, high-frequency welding. The latter method is also used in the welding of PU materials. Thus, the same method can be used in a linked system. For blisters 1 made of plastic foils welded together along a circumferential edge, these blisters 1 are usually produced prior to connection to the carrier 2. Only in a second step then the carrier 2 - or are additional components 3, 4, 5 connected to the finished bubbles 1. However, the production of the bubble 1 by welding the films simultaneously with the connection with the carrier 2 in a single operation is possible. In order to improve the fatigue strength of the system, the features illustrated in FIGS. 4a to 4c are advantageously provided. During the welding process, the edge region 1b of the bladder 1 as well as the material of the carrier 2 are heated. The tool 7 presses both materials together after the reflow process. In order to avoid edges of the welding points or lines embossed on the edges of the tool, which can negatively influence the fatigue strength, it is advantageous to provide rounded edges of the tool edges, as for the straight tool 7 of FIG. 4 a or the annular tool 7 b of FIG. 4c shown. A structuring of the tool surface of the tool 7a by simple, transverse or longitudinal pulling through the tool waves, as in Fig. 4b, would be possible. In FIGS. 5a and 5b, two different arrangements of bladder 1 and carrier material 2 are shown in side view during welding, as selected especially when using HF methods. On a welding table 8 carrier 2, especially made of felt, and the bladder 1, especially made of plastic film, placed. An upper tool 7 in the form of the future weld 40 then takes over the connection of the components 1, 2. If the bubble 1 on the support 2, penetrates the upper tool 7 strong in the film material of the bladder 1 a. If, on the other hand, the felt of the carrier 2 lies on the bladder 2, the felt is lowered toward the blister side. Depending on the application, different properties can be achieved by these arrangements. Claims 1.
