Abstract
Description
Die vorliegende Erfindung betrifft eine Rückenlehne für einen Fahrzeugsitz gemäß der Patentanmeldung 10 2005 013 020.The The present invention relates to a backrest for a vehicle seat according to the patent application 10 2005 013 020.
Die Hauptanmeldung 10 2005 013 020 betrifft eine Rückenlehne für einen Fahrzeugsitz mit einem ersten Lehnenteil, welches eine in Querrichtung abstehende untere Verlängerung aufweist. Neben dem ersten Lehnenteil ist ein zweites Lehnenteil angeordnet, welches an der unteren Verlängerung des ersten Lehnenteils klappbar angelenkt ist. Die beiden Lehnenteile sind in ihrem oberen Bereich aneinander verriegelbar. Nach dem Lösen dieser oberen Verriegelung kann das zweite Lehnenteil separat vom ersten Lehnenteil um eine Schwenkachse nach vorne geklappt werden, um eine Durchlademöglichkeit zu schaffen.The Main application 10 2005 013 020 relates to a backrest for a vehicle seat with a first backrest part, which has a transversely projecting lower renewal having. In addition to the first backrest part is a second backrest part arranged, which at the lower extension of the first backrest part hinged hinged. The two backrest parts are in their upper Lockable area. After loosening this upper lock can the second backrest part separately from the first backrest part to a Swivel axis can be folded forward to a through-loading possibility to accomplish.
Aufgabe der Hauptanmeldung ist es, eine Rückenlehne zur Verfügung zu stellen, die ein von einem Benutzer mit geringem Aufwand vom ersten Lehnenteil zu entriegelndes und nach Entriegelung vorklappbares zweites Lehnenteil aufweist, welches eine hohe Sicherheit, insbesondere auch bei einem Front-Crash, gewährleistet.task The main application is to have a backrest available Make one by a user with little effort from the first set of backs To unlock and after unlocking hinged second backrest part having a high security, especially in a front crash, guaranteed.
Die Lösung dieser Aufgabe besteht nach der Hauptanmeldung darin, dass zwischen einem unteren Bereich des zweiten Lehnenteils und der unteren Verlängerung des ersten Lehnenteils eine Crash-Verriegelungseinrichtung vorgesehen ist, die bei langsamem Vorklappen des zweiten Lehnenteils, also im normalen Gebrauch, nicht aktiviert und bei schnellem Vorklappen oder nach vorne Verwinden des zweiten Lehnenteils bei einem Front-Crash aktiviert ist.The solution This object is according to the parent application that between a lower portion of the second backrest part and the lower extension provided the first backrest part a crash locking device is, when slowly folding the second backrest part, so in normal use, not activated and with fast folding or forward twisting of the second backrest part in a front crash is activated.
Aufgabe der vorliegenden Erfindung ist es, eine weitere Ausführungsform einer Rückenlehne gemäß der Hauptanmeldung zur Verfügung zu stellen.task The present invention is another embodiment a backrest according to the parent application to disposal to deliver.
Diese Aufgabe wird erfindungsgemäß mit einer Rückenlehne gelöst, die die Merkmale des Anspruchs 1 aufweist.These Task is according to the invention with a backrest solved, having the features of claim 1.
Es soll hier vorausgeschickt werden, dass nachfolgend, auch in den Patentansprüchen, unter den Begriffen „Innenseite" und „Außenseite" die einander benachbarten bzw. die nicht benachbarten Seiten des ersten und zweiten Lehnenteils zu verstehen sind.It should be sent here in advance, that below, also in the Claims, under the terms "inside" and "outside" the adjacent ones or the non-adjacent sides of the first and second backrest part to be understood.
Im Falle eines Front-Crashs bleibt die relative Lage der Innenseite des zweiten Lehnenteils zur Innenseite des ersten Lehnenteils aufgrund der oberen Verriegelung zwischen diesen beiden Lehnenteilen bestehen, während sich die Außenseite des zweiten Lehnenteils nach vorn verwindet. Diese Verwindung kann durch aus dem Gepäckraum auf die Rückseite des zweiten Lehnenteils auftreffende Ladung noch verstärkt werden und letztlich dazu führen, dass das zweite Lehnenteil aus der Verriegelung mit dem ersten Lehnenteil ausreißt und sich dann um die Schwenkachse frei nach vorn bewegen kann. Um dies zu vermeiden, ist die erfindungsgemäße Crash-Verriegelungseinrichtung vorgesehen. Da sich – wie oben schon dargelegt – die relative Lage der Innenseite des zweiten Lehnenteils zum ersten Lehnenteil bei einem Front-Crash zumindest nicht wesentlich ändert, bleibt auch das Halteelement in Anlage an das erste Ende des Crashbolzens, so dass dieser gegen die Kraft der ihn in Entriegelungsrichtung beaufschlagenden Druckfeder in Verriegelungsstellung gehalten bleibt, in der er mit seinem zweiten Ende in die Eingriffsöffnung des Fangelements eingreift. Die Verwindung des zweiten Lehnenteils wird gestoppt, wenn der Crashbolzen an die hintere Wandung der länglichen Eingriffsöffnung anschlägt.in the In case of a front crash, the relative position of the inside remains of the second backrest part to the inside of the first backrest part due the upper interlock between these two backrest parts, while the outside of the second backrest part twisted forward. This twist can through from the luggage compartment on the back The second part of the backrest incident charge be reinforced and ultimately cause that the second backrest part of the lock with the first backrest part uproots and then can move freely forward about the pivot axis. To this to avoid the crash locking device according to the invention is provided. Because - like already explained above - the relative position of the inside of the second backrest part to the first Backrest part in a front crash, at least not substantially changes remains also the holding element in abutment with the first end of the crash pin, so that this against the force of him acting in the unlocking direction Compression spring held in the locked position remains, in which he with engages its second end in the engagement opening of the Fangelements. The twist of the second backrest part is stopped when the crash bolt to the rear wall of the elongated engagement opening strikes.
Wenn das zweite Lehnenteil im normalen Gebrauch nach vorn geklappt werden soll, um eine Durchlademöglichkeit aus dem Gepäckraum zu schaffen, wird zunächst die Verriegelung mit dem ersten Lehnenteil gelöst. Das zweite Lehnenteil kann nun um seine an der unteren Verlängerung des ersten Lehnenteils ausgebildeten Schwenkachse nach vorn geklappt werden. Durch dieses Vorklappen des zweiten Lehnenteils kommt das auf seiner Innenseite angeordnete Halteelement vom ersten Ende des Crashbolzens frei, so dass dieser durch die Kraft der Druckfeder in seine Entriegelungsstellung verschoben wird. Da für das Erreichen dieser Entriegelungsstellung des Crashbolzens zumindest ein geringfügiges nach vorn Klappen des zweiten Lehnenteils erforderlich ist, muss die Eingriffsöffnung des Fangelements eine diesem erforderlichen Klappweg entsprechende Länge aufweisen.If the second backrest part can be folded forward in normal use is supposed to be a through-loading opportunity from the luggage compartment to create, first the lock with the first backrest part solved. The second backrest part can now around his at the lower extension the first backrest part formed pivot axis folded forward become. By this folding the second backrest part that comes arranged on its inside retaining element from the first end of the crash pin free, so that this by the force of the compression spring in its unlocked position is moved. Therefore the achievement of this unlocking position of the crash bolt at least a slight one front flaps of the second backrest part is required, must the intervention opening the Fangelements this required folding path Have length.
Die erfindungsgemäße Crash-Verriegelungseinrichtung verhindert also bei einem Frontcrash ein übermäßiges Verwinden des zweiten Lehnenteils auf seiner Außenseite nach vorn, behindert aber gleichzeitig ein Vor- und Zurückklappen des zweiten Lehnenteils im normalen Gebrauch nicht.The Crash-locking device according to the invention Prevents excessive twisting of the second during a frontal crash Lehnenteils on its outside forward, but hinders at the same time a forward and backward folding of the second backrest part in normal use.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the Dependent claims.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. In der dazugehörigen Zeichnung zeigt:The Invention will be explained in more detail with reference to an embodiment. In the associated Drawing shows:
