Abstract
Description
Die vorliegende Erfindung betrifft eine Rückenlehne eines Kraftfahrzeug-Sitzes gemäß dem Oberbegriff des Patentaspruchs 1.The The present invention relates to a backrest of a motor vehicle seat according to the generic term of patent claim 1.
Eine
derartige Rückenlehne
ist aus der
Die
beiden Lehnenteile sind auf ihren Außenseiten mit der Karosserie
des Fahrzeugs verriegelbar. Auf der Innenseite wird durch die die
Fuge zwischen den beiden Lehnenteilen überbrückende Kopfstütze eine
gewisse Verblockung der beiden Lehnenteile erreicht. Allerdings
ist die Kopfstütze
nicht so verwindungssteif, dass sie im Falle eines Unfalls eine Relativbewegung
der beiden Lehnenteile zueinander verhindern kann. Daher ist bei
der Lösung
gemäß der
Um eines der beiden Lehnenteile umklappen zu können, muss die mittlere Kopfstütze mit ihren Tragstangen aus den beiden Lehnenteilen herausgezogen werden. Dadurch kommt der Hebel frei und zieht aufgrund der auf ihn einwirkenden Vorspannung den Verriegelungsbolzen in seine Entriegelungsstellung.Around To fold one of the two backrest parts, the middle headrest must be with their support rods are pulled out of the two backrest parts. As a result, the lever is released and pulls due to the acting on him Preload the locking bolt in its unlocked position.

Der oben im Zusammenhang mit einer gattungsgemäßen Rückenlehne beschriebene Verriegelungsmechanismus im Fugenbereich der beiden Lehnenteile ist technisch relativ aufwändig. Es ist daher Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Rückenlehne zur Verfügung zu stellen, bei der bei in Gebrauchsstellung befindlicher Kopfstütze mit sehr einfachen Mitteln eine wirksame Verriegelung bzw. Verblockung der beiden Lehnenteile auf ihrer Innenseite gewährleistet ist.Of the above in connection with a generic backrest described locking mechanism in the joint area of the two backrest parts is technically relatively complex. It is therefore an object of the present invention, a generic backrest to disposal to put in when in befindlicher position headrest with very simple means an effective locking or blocking the two backrest parts is guaranteed on their inside.
Die oben gestellte Aufgab wird erfindungsgemäß mit einer Rückenlehne gelöst die die Merkmale de Patentanspruchs 1 aufweist.The Above asked task is inventively with a backrest solved having the features of claim 1.
Ein solches Verbindungselement kann im einfachsten Falle eine die beiden Tragstangen starr verbindende Verbindungsstange sein.One Such a connection element can in the simplest case one the two Be support rods rigidly connecting rod.
In vorteilhafter Ausgestaltung der Erfindung ist jedoch das Verbindungselement über hülsenartige, die Tragstangen umgreifende Endbereiche unter Schwerkraftwirkung an den Tragstangen verschiebbar geführt, d. h., bei einer Höhenverstellung der Kopfstütze schieben sich deren Tragstangen durch die Endbereiche des Verbindungselements hindurch ohne dieses mitzunehmen. Dadurch ist gewährleistet, dass sich das Verbindungselement bei jeder Höheneinstellung der Kopfstütze, bezogen auf diese, immer in der tiefstmöglichen Position befindet. Diese tiefstmögliche Position ist in optimaler Weise dann gegeben, wenn das Verbindungselement auf den Oberseiten der Lehnenteile aufliegt, da in dieser Position eine sehr effektive Verblockung zwischen den Lehnenteilen erreicht wird.In Advantageous embodiment of the invention, however, the connecting element via sleeve-like, the support rods encompassing end portions under gravity slidably guided on the support rods, d. h., at a height adjustment the headrest push their support rods through the end portions of the connecting element through without taking this. This ensures that that the connecting element at each height adjustment of the headrest, related on this, always in the lowest possible Position is located. This lowest possible Position is optimally given when the connecting element rests on the tops of the backrest parts, as in this position Achieved a very effective interlocking between the backrest parts becomes.
Diese Wirkung wird kaum verringert, wenn aus ästhetischen bzw. optischen Gründen das Verbindungselement in den Lehnenteilen, vorzugsweise bündig, versenkt ist. Das kann dadurch erreicht werden, dass in den Lehn nenteilen an entsprechender Stelle eine Vertiefung für das Verbindungselement vorgesehen ist.This effect is hardly reduced if, for aesthetic or optical reasons, the Ver binding element in the backrest parts, preferably flush, sunk. This can be achieved in that in the Lehn nenteilen at the appropriate place a recess for the connecting element is provided.
Um Klappergeräusche zwischen dem Verbindungselement und den Tragstangen zu verhindern, sind in weiterer Ausgestaltung der Erfindung zwischen den hülsenartigen Endbereichen des Verbindungselements und der zugeordneten Tragstange Federmittel angeordnet.Around rattling noises between the connecting element and the support rods to prevent are in a further embodiment of the invention between the sleeve-like End portions of the connecting element and the associated support rod spring means arranged.
In einer weiteren Ausführungsform der Erfindung weist mindestens eine der Tragstangen im Höhenverstellbereich der Kopfstütze eine Abflachung auf, wobei mit dieser Abflachung zusammenwirkende Rastmittel vorgesehen sind. Dadurch wird ein Abrutschen des Verbindungselements bei aus den Lehnenteilen herausgezogenen Tragstangen verhindert. Als Rastmittel können die zwischen den hülsenartigen Endbereichen des Verbindungselements und den Tragstangen vorgesehenen Federmittel dienen.In a further embodiment The invention comprises at least one of the support rods in the height adjustment the headrest a flattening on, cooperating with this flattening Locking means are provided. This will cause the connecting element to slip off prevented when pulled out of the backrest support rods. When Locking means can the between the sleeve-like End portions of the connecting element and the support rods provided Serve spring means.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. In der dazugehörigen Zeichnung zeigt in rein schematischer Weise:The Invention will be explained in more detail with reference to an embodiment. In the associated Drawing shows in a purely schematic way:
