Description
Die Erfindung betrifft eine Quertraverse für eine Sitzstruktur in einem Kraftfahrzeug, nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a crossbeam for a seat structure in a motor vehicle, according to the closer defined in the preamble of
Für eine elektrische Sitzverstellung in einem Kraftfahrzeug sind sogenannte Quertraversen vorgesehen, die in der Sitzstruktur unter dem Sitz quer verlaufend angeordnet sind und mit den seitlichen Sitzschienen über Befestigungsglieder verbunden sind. Dabei wird an einer Halteplatte, die im Allgemeinen bauraumbedingt über ein Rohr mit seitlichen Anschraubwinkeln verschweißt ist, der Antriebsmotor verschraubt. In bzw. an dem Querträger ist auch die Antriebswelle für den Motor zu einem Schneckentrieb in der Sitzschiene angeordnet. Der Querträger ist aus einem Stahlteil gebildet. An dem Querträger sind weiterhin Zusatzbauteile angeordnet, wie z. B. Befestigungsglieder für einen Kabelbaum.For an electric seat adjustment in a motor vehicle so-called crossbeams are provided, which are arranged transversely in the seat structure under the seat and are connected to the side seat rails via fastening members. In this case, the drive motor is bolted to a holding plate, which is generally welded space-related via a pipe with lateral Anschraubwinkeln. In or on the cross member and the drive shaft for the motor is arranged to a worm drive in the seat rail. The cross member is made of a steel part. On the cross member additional components are arranged such. B. fasteners for a wiring harness.

Die
Der Antriebsmotor und die Antriebswelle befinden sich jedoch im Fußraum des Kraftfahrzeugs und dies bedeutet, es besteht die Gefahr einer Beschädigung, wenn z. B. der vordere Sitz ganz nach hinten gefahren wird und der hintere Passagier die Füße in dem Verfahrbereich platziert hat. Ebenso besteht eine Gefährdung, wenn im Fußraum Teile abgelegt sind, die bei einer Sitzverstellung nach hinten ebenfalls den Antriebsmotor und die Antriebswelle beschädigen können.However, the drive motor and the drive shaft are located in the footwell of the motor vehicle and this means there is a risk of damage when z. B. the front seat is moved all the way to the rear and the rear passenger has placed the feet in the travel area. Likewise, there is a risk if parts are stored in the footwell, which can also damage the drive motor and the drive shaft in a seat adjustment to the rear.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Quertraverse zu schaffen, die weniger Bauteile aufweist und damit eine Montageerleichterung bringt und die den Antriebsmotor und die Antriebswelle vor Beschädigungen schützt.The present invention has for its object to provide a cross-beam, which has fewer components and thus brings a mounting relief and protects the drive motor and the drive shaft from damage.
Die vorstehend genannte Aufgabe wird erfindungsgemäß durch eine Quertraverse mit den in Anspruch 1 genannten Merkmalen gelöst.The above object is achieved by a cross-beam with the features mentioned in
Durch die Ausbildung aus einem endlosfaserverstärktem Thermoplast, z. B. aus einem Organoblech, ergibt sich zum einen eine deutliche Gewichtserleichterung und zum anderen auch eine drastische Reduzierung von Bauteilen. So kann z. B. die gesamte Quertraverse als Umform- und Spritzgussteil in einem Arbeitsgang mit allen Anbau- und Zusatzteilen hergestellt werden.By training from a continuous fiber reinforced thermoplastic, z. B. from an organic sheet, on the one hand results in a significant weight reduction and on the other hand, a drastic reduction of components. So z. B. the entire cross-beam as forming and injection molding in one operation with all attachments and accessories are made.
Eine Herstellung des erfindungsgemäßen Querträgers aus dem endlosfaserverstärkten Thermoplast bedeutet auch, dass die Formgebung variabel ist und damit jeweils optimal an die Raumsituation angepasst werden kann. Gleiches gilt für Versteifungs- und Verstärkungsabschnitte, sowie für Anbauteile.A production of the cross member according to the invention from the continuous fiber reinforced thermoplastic also means that the shape is variable and thus each can be optimally adapted to the room situation. The same applies to stiffening and reinforcement sections, as well as attachments.
Durch eine Umhüllung von Motor und Antriebswelle in Form einer Halbschale wird gleichzeitig eine Schutzfunktion gegen Beschädigungen und eine Geräuschreduzierung erreicht.By a cladding of motor and drive shaft in the form of a half-shell, a protective function against damage and noise reduction is achieved at the same time.
Aus Stabilitätsgründen ist der Querträger mit seitlichen Versteifungsschienen versehen, wobei im Bedarfsfalle auch noch zusätzliche Versteifungsrippen zwischen der Halbschale und den Versteifungsschienen vorgesehen werden können.For stability reasons, the cross member is provided with lateral stiffening rails, wherein in case of need also additional stiffening ribs between the half shell and the stiffening rails can be provided.
Vorteilhafte Weiterbildungen und Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen und aus den nachfolgenden, anhand der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispielen.Advantageous developments and refinements emerge from the further subclaims and from the following exemplary embodiments described in principle with reference to the drawing.
