Abstract
Description
Die Erfindung betrifft eine elektromotorische Sitzverstelleinrichtung für ein Fahrzeug, insbesondere für ein Kraftfahrzeug gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an electromotive seat adjustment for a Vehicle, especially for a motor vehicle according to the preamble of claim 1
Eine
derartige Sitzverstelleinrichtung mit einer in einem Motorgehäuse aus
Metall aufgenommenen Antriebseinheit ist z. B. in der
Die
Der zusätzliche Fertigungs- und Kostenaufwand für derartige Kunststoffaufnahmen ist jedoch relativ hoch. Hierbei zeigt sich, dass im Verhältnis zum Aufwand die bei Einsatz des Motorgehäuses in derartige Kunststoffaufnahmen erreichte Geräuschminimierung nur gering ist.Of the additional Production and costs for However, such plastic recordings is relatively high. This shows itself, that in relation to Effort when using the motor housing in such plastic receptacles reached noise minimization only small.
Vor diesem Hintergrund ist es die Aufgabe der Erfindung, eine elektromotorische Sitzverstelleinrichtung der eingangs genannten Art zu schaffen, die mit geringen Fertigungskosten eine hohe Schallisolation gewährleistet.In front In this background, it is the object of the invention, an electromotive Seat adjustment of the aforementioned type to create which ensures a high sound insulation with low production costs.
Diese Aufgabe wird durch eine elektromotorische Sitzverstelleinrichtung nach Patentanspruch 1 gelöst. Die Unteransprüche beschreiben bevorzugte Weiterbildungen.These Task is by an electromotive seat adjustment solved according to claim 1. The dependent claims describe preferred developments.
Der
Erfindung liegt die überraschende
Entdeckung zu Grunde, dass durch eine Beschichtung des metallischen
Motorgehäuses
mit einer organischen Substanz auf seiner Außenseite, bei der die organische
Substanz auf der Außenseite
haftet, eine deutliche Verringerung der Schallemission erreicht werden
kann. Gründe
hierfür
können
z.B. in der Schwingungsunterdrückung
durch die Haftung bzw. den Stoffschluss der organischen Substanz
liegen. Hierbei wurde entdeckt, dass für eine Geräuschverringerung eine Beschichtung
der Außenseite
des metallischen Motorgehäuses
deutlich relevanter ist als die Anbringung von aufwändigen stirnseitigen
Dämpfungen,
wie sie z. B. in der
Es ergaben sich insbesondere deutliche Verringerungen der Geräuschemission bei Verwendung von Bitumen als organischer Beschichtung. Eine derartige Beschichtung mit Bitumen kann durch einfaches Eintauchen des Motors in ein Bitumenbad bei verkapselten Motorstirnseiten oder Aufbringen einer Bitumenschicht durch Wickeln oder als Hülse und nachfolgendes stoffschlüssiges Verbinden durch z. B. Druck und Wärme ausgebildet werden.It In particular, significant reductions in noise emission resulted when using bitumen as an organic coating. Such Coating with bitumen can be achieved by simply submerging the motor in a bitumen bath with encapsulated motor end faces or application a bitumen layer by winding or as a sleeve and subsequent cohesive bonding by z. B. pressure and heat be formed.
Weiterhin ist erfindungsgemäß auch die Verwendung eines Sandwich-Blechs aus Blech-organischem Material-Blech mit haftender bzw. stoffschlüssiger Verbindung zwischen dem Blech und dem organischen Material möglich.Farther is according to the invention also the Use of a sandwich sheet of sheet-organic material sheet with adhesive or cohesive Connection between the sheet and the organic material possible.
Erfindungsgemäß konnte bereits mit einer durch Eintauchen ausgebildeten, einfachen Bitumenbeschichtung eine Reduzierung der Schallemission einer Sitzverstelleinrichtung um 6 dBA erreicht werden.According to the invention could already with a simple bitumen coating formed by dipping a reduction of the sound emission of a seat adjuster be achieved by 6 dBA.
Die erfindungsgemäße Sitzverstelleinrichtung ist vorteilhafterweise in dem Frequenzbereich von 5 bis 10 KHz betreibbar.The Seat adjustment according to the invention is advantageously operable in the frequency range of 5 to 10 KHz.
Die Erfindung wird im Folgenden anhand der beiliegenden Zeichnungen an einer Ausführungsform erläutert. Es zeigen: The Invention will be described below with reference to the accompanying drawings explained on an embodiment. It demonstrate:
