Description
Die Erfindung betrifft einen Fahrzeugsitz gemäß dem Oberbegriff des Anspruchs 1. Weiter betrifft die Erfindung ein Vliesformteil und ein Polsterelement zur Herstellung von Fahrzeugsitzen.The The invention relates to a vehicle seat according to the preamble of the claim 1. The invention further relates to a nonwoven molded part and a cushion element for the production of vehicle seats.

Weiterhin ist es bekannt, Abheftdrähte in ein das Polsterelement bildenden Schaumkörper einzuschäumen. Beim Beziehen des Polsterelements werden dann am Bezug befestigte Abheftelemente, beispielsweise Abheftklammern, in dafür vorgesehenen Abheftpunkten am eingeschäumten Abheftdraht eingehängt.Farther it is known, filing wires into a foam body forming the cushioning element. At the Obtaining the upholstery element then attached to the cover Abheftelemente, For example, staples, in designated Abheftpunkten on the foamed Filing wire hooked.
Nachteilig an der Lösung mit eingeschäumten Abheftdrähten ist es, dass die Ausreißkräfte der Drähte im Wesentlichen von der Schaumdicke abhängt, so dass die Wandstärke des Schaumkörpers nach unten begrenzt ist. Denn bei einer zu geringen Schaumüberdeckung werden keine ausreichend hohen Ausreißkräfte mehr gewährleistet.adversely at the solution with foamed Abheftdrähten it is that the pull-out forces of the wires in essence depends on the foam thickness, so the wall thickness the foam body after is limited below. Because with too little foam coverage no sufficiently high pull-out forces are guaranteed.
Ausgehend von diesem Stand der Technik ist es deshalb Aufgabe der vorliegenden Erfindung einen neuen Fahrzeugsitz vorzuschlagen, der die Nachteile des vorbekannten Stands der Technik vermeidet. Weiter ist es Aufgabe der vorliegenden Erfindung Vliesformteile und Polsterelemente zur Herstellung dieser neuartigen Fahrzeugsitze vorzuschlagen.outgoing From this prior art, it is therefore an object of the present Invention to propose a new vehicle seat, the disadvantages of the prior art avoids. It's up to you to continue the present invention nonwoven moldings and upholstery elements for To propose production of this novel vehicle seats.
Diese Aufgabe wird durch Gegenstände nach der Lehre der unabhängigen Hauptansprüche gelöst.These Task is by objects after the doctrine of the independent Main claims solved.
Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.advantageous embodiments The invention are the subject of the dependent claims.
Der erfindungsgemäße Fahrzeugsitz beruht auf dem Grundgedanken, dass am oder im Polsterelement ein aus einem Vliesmaterial hergestelltes Formteil vorgesehen ist, an dem seinerseits die Befestigungselemente zur Fixierung der Abheftelemente befestigt sind. Dies bedeutet mit anderen Worten, dass die Haltekräfte zur Befestigung des Bezuges am Polsterelement von den Abheftelementen über die daran befestigten Befestigungselemente in das Vliesformteil eingeleitet und von dort großflächig auf das Polsterelement verteilt werden. Durch diese großflächige Verteilung der Haltekräfte ist es möglich auch bei sehr dünnwandigen Polsterelementen ausreichend hohe Ausreißkräfte zu realisieren.Of the Vehicle seat according to the invention is based on the idea that on or in the upholstery element a is provided from a nonwoven material molded part, at in turn, the fasteners for fixing the Abheftelemente are attached. This means in other words that the holding forces for Fixing the cover to the upholstery element of the Abheftelementen over the fastened fasteners introduced into the nonwoven molding and from there on the large area Upholstered element to be distributed. By this large-scale distribution of holding forces it is possible too in very thin-walled Padding elements sufficiently high tear-out to realize.
An welcher Stelle des Polsterelements das Vliesformteil angeordnet ist, ist grundsätzlich beliebig. Besonders hohe Ausreißkräfte ergeben sich, wenn das Vliesformteil auf der vom Bezug abgewandten Innenseite des Polsterelements insbesondere formschlüssig angeordnet ist. Auf diese Weise durchgreifen die Abheftelemente das Polsterelement nicht, wie bei anderen Ausführungsformen, nur ein stückweit, sondern über die volle Wandstärke, so dass zur Einleitung der Haltekräfte die gesamte Bauteilwandung des Polsterelements, beispielsweise eines Schaumkörpers, zur Verfügung steht.At which point of the cushioning element arranged the nonwoven molding is, is basically any. Particularly high pull-out results when the nonwoven molding on the inside facing away from the cover the cushion element is arranged in particular form-fitting manner. To this Way, the filing elements do not penetrate the padding element, as in other embodiments, just a bit, but about the full wall thickness, so that the introduction of the holding forces the entire component wall the cushioning element, for example a foam body, for disposal stands.
Eine Befestigung des Vliesformteils am Polsterelement vor der Anbringung des Bezuges ist nicht unbedingt erforderlich. Jedoch wird das Handling der beiden Bauteile erheblich dadurch vereinfacht, dass Vliesformteil und Polsterelement zu einem Bauteil miteinander verbunden sind. Dies kann besonders einfach und kostengünstig dadurch geschehen, dass das Vliesformteil bei der Herstellung des Polsterelements mit einem geeigneten Polymer, beispielsweise Polyurethan eingeschäumt oder angeschäumt wird. Nach der Entformung des Posterelements aus der Schäumform ist das Vliesformteil dann integraler Bestandteil des Schaumkörpers.A Attachment of the nonwoven molding to the padding element before attachment the cover is not essential. However, the handling is the two components significantly simplified by that nonwoven molding and upholstery element are connected together to form a component. This can be done particularly simply and inexpensively by the fact that the Nonwoven molded part in the manufacture of the cushion element with a suitable polymer, such as polyurethane foamed or foamed becomes. After the demolding of the poster element from the foaming mold is the nonwoven molding then integral part of the foam body.
Eine weitere Erhöhung der Ausreißkräfte bzw. eine weitere Verbesserung des Bauteilhandlings wird erreicht, wenn das Vliesformteil soweit verfestigt ist, dass es eine gewisse Formstabilität bietet. Diese Verfestigung des Vliesformteils kann insbesondere dadurch in einfacher Weise erreicht werden, dass thermisch verfestigbare Vliesmaterialien zur Herstellung des Vliesformteils eingesetzt werden. Diese thermisch verfestigbaren Vliesmaterialien können in beheizten Prägeformen durch Wärmezufuhr in der gewünschten Form verfestigt werden. Insbesondere haben sich Polyethylenvliesmaterialien als besonders geeignet zur Herstellung der erforderlichen Vliesformteile erwiesen.A further increase the break-out forces or a further improvement of the component handling is achieved, if the nonwoven molded part is solidified so far that it offers a certain dimensional stability. These Solidification of the nonwoven molded part can thereby in particular easier Be achieved, that thermally solidifiable nonwoven materials be used for the production of the nonwoven molding. This thermally solidifiable nonwoven materials can be heated in embossing forms by heat in the desired Form solidified. In particular, polyethylene nonwoven materials have as particularly suitable for producing the required nonwoven moldings proved.
In welcher Weise die Befestigungselemente zur Befestigung der Abheftelemente am Vliesformteil befestigt sind, ist grundsätzlich beliebig. Nach einer Ausführungsform ist es vorgesehen, dass die Befestigungselemente in die Wandung des Vliesformteils eingebettet werden. Dazu können die Befestigungselemente bei Verwendung von thermisch verfestigbaren Vliesmaterialien während des Heißprägeprozesses in die Prägeform eingelegt und zusammen mit dem zunächst flauschigen Vliesmaterial unter Wärmeeinwirkung verpresst werden.In which way the fasteners for fastening the Abheftelemente are attached to the nonwoven molding, is basically arbitrary. According to one embodiment It is envisaged that the fasteners in the wall embedded of the nonwoven molding. These can be the fasteners when using thermally solidifiable nonwoven materials during the Hot stamping process in the stamping mold inserted and together with the initially fluffy nonwoven material under heat be pressed.
Alternativ bzw. additiv zum Einbetten der Befestigungselemente können diese auch dadurch am Vliesformteil fixiert werden, dass sie zwischen zwei Schichten aus Vliesmaterial angeordnet werden. Durch Verpressen der beiden Schichten aus Vliesmaterial unter Wärmeeinwirkung können die beiden Schichten unter Einschluss des Befestigungselements miteinander verbunden werden.alternative or additively for embedding the fasteners they can Also be fixed by the nonwoven molding that between two layers of nonwoven material are arranged. By pressing The two layers of nonwoven material under heat, the two layers including the fastener together get connected.
Welche Art von Befestigungselemente zur Befestigung der Abheftelemente am Vliesformteil Verwendung finden, ist grundsätzlich beliebig. Nach einer ersten bevorzugten Ausführungsform werden dazu Abheftdrähte verwendet, die am Vliesformteil befestigt sind. Die Abheftdrähte können dabei sehr preisgünstig als gradlinige Drahtabschnitte ausgebildet sein, da aufgrund der Einbettung der Abheftdrähte im Vlies die ansonsten zur Verankerung der Abheftdrähte notwendigen Ösen an den Drahtenden entfallen können.Which Type of fasteners for attaching the Abheftelemente On nonwoven molded part use, is basically arbitrary. After a first preferred embodiment to be filing wires used, which are attached to the nonwoven molding. The filing wires can do this very reasonably priced be designed as straight wire sections, since due to the Embedding the filing wires in fleece the otherwise necessary for anchoring the Abheftdrähte eyelets to the Wire ends can be omitted.
Besonders hohe Ausreißkräfte werden erzielt, wenn die Abheftdrähte auf der vom Polsterelement abgewandten Seite des Vliesformteils angeordnet sind und somit im Belastungsfall auf ihrer gesamten Länge gegen das Vliesformteil gezogen werden.Especially high pull-out forces are scored when the filing wires on the side facing away from the pad element side of the nonwoven molding are arranged and thus in the load case over its entire length against the nonwoven molding to be pulled.
Zur Befestigung der Abheftelemente am Abheftdraht ist es besonders vorteilhaft, wenn die Abheftelemente das Vliesformteil durchgreifen und den Abheftdraht umgreifend am Abheftdraht eingehängt werden.to Fixing the filing elements on the filing wire it is particularly advantageous when the Abheftelemente pass through the nonwoven molding and the Abheftdraht be hanged around the filing wire.
Insbesondere das Einhängen von umgreifenden Abheftelementen wird erheblich erleichtert, wenn das Vliesformteil im Bereich der Abheftpunkte Ausnehmungen aufweist.Especially the hanging of embracing Abheftelementen is greatly facilitated when the nonwoven molded part has recesses in the region of the Abheftpunkte.
Alternativ bzw. additiv zur Verwendung von Abheftdrähten können am Vliesformteil auch Clipselemente befestigt sein, um funktionskomple mentäre Clipsbefestiger bei Befestigung des Bezuges an den Clipselementen einclipsen zu können.alternative or additive to the use of filing wires can also on the nonwoven molding Clip elements to be attached to functionally complementary clip fasteners when attaching the cover clips on to the clip elements can.
Eine Ausführungsform der Erfindung ist in den Zeichnungen schematisch dargestellt und wird nachfolgend beispielhaft erläutert.A embodiment the invention is shown schematically in the drawings and is explained below by way of example.
