Description
Die Erfindung betrifft ein Fahrzeugsitzelement für einen Fahrzeugsitz, insbesondere eine Rückenlehne, umfassend mindestens einen Polsterkern aus einem Weichschaum und ein rückseitig des Polsterkerns angeordnetes, mit dem Polsterkern verbundenes formstabiles Stützelement aus einem Hartschaum zum Stützen zumindest eines Teilbereiches des Polsterkernes.The The invention relates to a vehicle seat element for a vehicle seat, in particular a backrest comprising at least one Cushion core made of a soft foam and a back of the Padded core arranged, connected to the cushion core dimensionally stable Support element made of rigid foam for supporting at least a portion of the cushion core.
Die
Die getrennte Anordnung von Polsterkern und Stützelement am Rückenlehnenrahmen bedingt, dass Polsterkern und Stützelement als separate Teile vorliegen müssen. Es sind mindestens zwei Arbeitsschritte für die Anordnung von Polsterkern und Stützelement notwendig.The separate arrangement of cushion core and support element on Backrest frame requires that cushion core and support element must be present as separate parts. It is at least two steps for the arrangement of cushion core and support element necessary.
Aufgabe der vorliegenden Erfindung ist es, ein Fahrzeugsitzelement für einen Fahrzeugsitz in oben genannter Art zu schaffen, welches einfach und kostengünsig an einem Rahmen, beispielsweise einen Rückenlehnenrah men, montierbar ist. Eine weitere Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, das die Herstellung eines derartigen Fahrzeugsitzelementes ermöglicht.task The present invention is a vehicle seat element for to provide a vehicle seat in the above-mentioned way, which is easy and cost-effective on a frame, such as a Rückenlehnenrah men, is mountable. Another task The invention is to provide a method that the production allows such a vehicle seat element.
Diese Aufgaben werden durch ein Fahrzeugsitzelement und ein Verfahren zur Herstellung eines Fahrzeugsitzelementes nach den unabhängigen Ansprüchen gelöst.These Tasks are performed by a vehicle seat element and a method for producing a vehicle seat element according to the independent Claims solved.
Vorteilhafte Weiterbildungen sind Gegenstände der abhängigen Ansprüche.advantageous Developments are objects of the dependent Claims.
Das erfindungsgemäße Fahrzeugsitzelement umfasst mindestens einen Polsterkern aus einem Weichschaum und ein rückseitig des Polsterkerns angeordnetes mit dem Polsterkern verbundenes formstabiles Stützelement aus einem Hartschaum zum Stützen zumindest eines Teilbereiches des Polsterkerns, wobei Polsterkern und/oder Stützelement eine rückseitige Aussparung ausbilden, die ein rückseitiges Einsetzen eines Rahmens bei verbundenem Polsterkern und Stützelement ermöglicht.The The vehicle seat element according to the invention comprises at least a cushion core made of a soft foam and a back of the cushion core arranged with the cushion core dimensionally stable Support element made of rigid foam for supporting at least a portion of the cushion core, wherein cushion core and / or support member has a back recess train, which is a rear insertion of a frame allows for connected cushion core and support element.
Damit ist es möglich, Polsterkern und Stützelement mit dem Rahmen ohne großen Montageaufwand zu verbinden. Insbesondere ist es möglich, Stützelement und Polsterkern separat als ein diese beiden Elemente umfassendes Einzelteil herzustellen.In order to it is possible to use upholstery core and support element connect to the frame without much installation effort. Especially it is possible to support element and upholstery core separately as an item comprising these two elements.
Die Verbindung eines Polsterkerns aus einem Weichschaum und einem Stützelement aus einem Hartschaum ermöglicht es, andere Elemente zur Stützung des Polsterkerns, wie Metall- oder Kunststoffteile, gewichtssparend zu ersetzen. Des Weiteren kann durch das Stützelement aus Hartschaum eine gewisse Elastizität bei einem unüblich hohen Druck auf den Polsterkern gewährleistet werden, was zum Schutz eines Fahrzeuginsassen genutzt werden kann, insbesondere in dem der Körper des Fahrzeugsinsassen tiefer in den Lehnenrahmen eintauchen und sich damit einer Kopfstütze nähern kann.The Connection of a cushion core made of a soft foam and a support element made of a rigid foam allows other elements to Supporting the cushion core, such as metal or plastic parts, to save weight. Furthermore, by the support element made of hard foam a certain elasticity at an unusually high Pressure on the cushion core to be ensured, leading to Protection of a vehicle occupant can be used, in particular in which the body of the vehicle occupant dive deeper into the backrest frame and thus be able to approach a headrest.
Der Polsterkern kann einteilig, was erfindungsgemäß bevorzugt ist, oder mehrteilig sein. Ebenso kann das Stützelement einteilig oder mehrteilig ausgebildet sein. Die Aussparung wird vorzugsweise gemeinsam von Polsterkern und Stützelement ausgebildet. Insbesondere ist bevorzugt, dass das Stützelement in einem Teilbereich einen Teil eines in die Aussparung eingesetzten Rahmens hintergreift, wodurch eine Abstützung des Stützelementes direkt am Lehnenrahmen hergestellt werden kann.Of the Upholstery core can be one piece, which is preferred according to the invention is, or be multi-part. Likewise, the support element be formed in one piece or multiple parts. The recess will preferably formed together by cushion core and support element. In particular, it is preferred that the support element in a Part of a part of a frame inserted into the recess engages behind, creating a support of the support element can be produced directly on the backrest frame.
Der Hartschaum, aus dem das Stützelement besteht, hat vorzugsweise eine Rohdichte von mindestens 140 kg/m3 besonders bevorzugt eine Rohdichte im Bereich von 160–350 kg/m3. Für den Polsterkern können übliche, für die Polsterung von Fahrzeugsitzelementen verwendete Schaumstoffmaterialien vorgesehen sein. Besonders bevorzugt hat das Schaumstoffmaterial für den Polsterkern eine Rohdichte im Bereich von 50–80 kg/m3.The rigid foam of which the support element is made preferably has a bulk density of at least 140 kg / m 3, more preferably a bulk density in the range of 160-350 kg / m 3 . For the cushion core may be provided conventional, used for the upholstery of vehicle seat elements foam materials. Particularly preferably, the foam material for the cushion core has a bulk density in the range of 50-80 kg / m 3 .
Vorzugsweise ist das Fahrzeugsitzelement als Rückenlehne eines Fahrzeugsitzes ausgebildet. Eine Alternative wäre die Ausbildung des Fahrzeugsitzelementes als Sitzteil eines Fahrzeugsitzes.Preferably is the vehicle seat element as the backrest of a vehicle seat educated. An alternative would be the formation of the vehicle seat element as a seat part of a vehicle seat.
Gemäß dem erfindungsgemäßen Verfahren zur Herstellung eines solchen Fahrzeugsitzelementes wird mit einem weichen Schaummaterial ein Polsterkern geschäumt, und der Polsterkern mit einem ein Stützelement bildenden harten Schaummaterial hinterschäumt, oder mit einem harten Schaummaterial ein Stützelement geschäumt, und das Stützelement mit einem einen Polsternkern bildenden weichen Schaummaterial hinterschäumt, wobei beim Schäumen des Polsterkerns und/oder des Stützelementes ein Freiraum belassen wird, der eine rückseitige Aussparung ausbildet, die ein rückseitiges Einsetzen eines Rahmens bei verbundenen Polsterkern und Stützelement ermöglicht.According to the inventive method for producing such a vehicle seat member is foamed with a soft foam material, a cushion core, and the cushion core with a backing member forming a foam backing foam, or foamed with a hard foam material, a support element, and the support element with a cushion core forming soft foam material behind , wherein during the foaming of the cushion core and / or the support element, a free space is left, the one back tiger recess is formed, which allows a rear insertion of a frame with connected upholstery core and support element.
