Description
Die
Erfindung bezieht sich auf einen Fahrzeugsitz der im Oberbegriff
des Patentanspruchs 1 genannten und aus der
Die aus dieser Druckschrift bekannte Kopfstütze hat an ihrer dem Fahrzeuginsassen zugewandten Frontseite eine nach oben offene Ausnehmung, in der sich ein Polsterteil in seiner Ruhelage befindet. Dieses wird über eine aus einem Zylinder mit federbelasteten Kolben und einem Stützhebel bestehenden Verstelleinrichtung zwischen der Ruhelage und der nahe am Kopf des Fahrzeuginsassen liegenden Wirklage verlagert. Dabei wird das Polsterteil in Ruhelage an der Kopfstütze arretiert, während bei einem Fahrzeugcrash durch einen Sensor ein Signal ausgelöst und hierdurch über die Verstelleinrichtung das Polsterteil in die Wirklage verschwenkt wird. Da sich hierbei das Polsterteil auf der gleichen Höhenlage wie die Kopfstütze befindet und es vom Fahrzeuginsassen oftmals versäumt wird, diese auf eine an seine Körpergröße angepasste Höhenlage einzustellen, bietet das Polsterteil bei einem Fahrzeugcrash nicht immer eine optimale Sicherheit.The From this document known headrest has on her the vehicle occupants facing front an upwardly open recess in the a cushion is in its rest position. This one is about one from a cylinder with spring-loaded pistons and a support lever existing adjustment between the rest position and the near shifted at the head of the vehicle occupant Wirklage. there the upholstery is locked at rest on the headrest, while at a Vehicle crash triggered by a sensor a signal and thereby over the Adjusting pivoted the cushion part in the effective position becomes. As this is the upholstery at the same altitude like the headrest and is often missed by the vehicle occupant, this one adapted to his height altitude does not provide the cushion part in a vehicle crash always optimal safety.
Aufgabe der Erfindung ist es daher, eine Kopfstütze der im Oberbegriff des Patentanspruchs 1 genannten Art derart auszubilden, dass das Polsterteil sowohl bei ma nueller Betätigung als auch bei einer Verlagerung bei einem Fahrzeugcrash sich in einer solchen Position befindet, dass der Kopf des Fahrzeuginsassen optimal gegen Verletzungen geschützt ist.task The invention is therefore a headrest in the preamble of Claim 1 mentioned type in such a way that the cushion part both with manual operation as in a shift in a vehicle crash in a located in such a position that the head of the vehicle occupant optimally protected against injury is.
Zur Lösung der Aufgabe sind die im Patentanspruch 1 dargelegten Merkmale vorgesehen.to solution the object provided in claim 1 features are provided.
Da die zur Anlenkung des Polsterteils dienenden Schwenkhebel erfindungsgemäß derart an der Kopfstütze angelenkt sind, dass in Wirklage des Polsterteils dessen Oberkante oberhalb der Oberkante der Kopfstütze liegt, wird für eine manuelle oder crashbedingte Verlagerung des Polsterteils dieses zuverlässig nach oben verlagert und damit dem Fahrzeuginsassen ein optimaler Schutz geboten.There the pivoting lever serving for articulation of the cushion part according to the invention such on the headrest are hinged, that in Wirklage the upholstery part whose upper edge is located above the top edge of the head restraint, for a manual or Crash-induced displacement of the upholstery part this reliably after shifted up and thus the vehicle occupant optimum protection offered.
Die Schwenkhebel des Polsterteils verlaufen in dessen Ruhelage zwischen diesem und der Kopfstütze etwa gleich gerichtet schräg nach unten, während sie sich in der Wirklage des Polsterteils etwa waagrecht erstrecken (Merkmale des Patentanspruchs 2).The Pivoting lever of the upholstery part run in its rest position between this and the headrest about the same direction oblique down while they extend approximately horizontally in the Wirklage the upholstery (Features of claim 2).
Unabhängig von der manuellen Verlagerung des Polsterteils über die beiden Schwenkhebel kann das Polsterteil auch manuell über eine am oberen Rand der Kopfstütze vorgesehene, in Fahrzeugquerrichtung verlaufende Schwenkachse zum Kopf des Fahrzeuginsassen hin ausgeschwenkt werden. Hierbei werden jedoch die Schwenkhebel nicht zur manuellen Verlagerung des Polsterteils benutzt, sondern lediglich nach Entriegelung federbelastet in Wirklage gebracht.Independent of the manual displacement of the upholstery part via the two pivot levers The upholstery can also be done manually via one at the top of the headrest provided, extending in the vehicle transverse direction pivot axis for Be swung head of the vehicle occupant back. Here are However, the pivot lever not for manual displacement of the cushion part used, but only spring-loaded after unlocking brought into the original position.
Im Crashfall wird ein in der Rückenlehne angeordnetes Auslöselement betätigt, das aus einem Beaufschlagungselement, einem Bowdenzug und einer im Hohlraum der Tragstangen vorgesehenen Schubstange besteht, wobei die Hülle des Bowdenzugs an einem Schieber befestigt ist. Hierbei wird bei einem Fahrzeugcrash durch Krafteinwirkung des Beaufschlagungselements durch den Rücken des Fahrzeuginsassen das Polsterteil in die Wirklage selbsttätig verlagert (Merkmale des Patentanspruchs 4).in the Crash case becomes one in the backrest arranged trigger element actuated, that of a loading element, a Bowden cable and a in the cavity of the support rods provided push rod, wherein the case of the Bowden cable is attached to a slider. This is at a Vehicle crash due to the action of force of the loading element through the back of the vehicle occupant automatically displaced the padded part into the operative position (Features of claim 4).
Gemäß den Merkmalen der Patentansprüche 5 und 6 steht vom oberen Rahmenquerteil der Rückenlehne oder auch – beispielsweise bei einer Rücksitzbank – vom Fahrzeugaufbau ein Aufnahmeteil nach unten ab, an dem ein Schieber höhenverlagerbar vorgesehen ist, wobei in diesen die rohrförmigen Tragstangen durch eine bloße Schnappwirkung einrastbar sind.According to the characteristics of the claims 5 and 6 is the upper frame cross member of the backrest or even - for example at a rear seat - from the vehicle body a receiving part down from where a slider höhenverlagerbar is provided, in which the tubular support rods by a nakedness Snap effect can be latched.
Das Polsterteil kann nach seiner Entriegelung über ein sensorgesteuertes Auslöseelement oder dergleichen durch eine längsverlagerbare Einrichtung wie Hubzylinder, Zahnstange oder dergleichen, zum Fahrzeuginsassen hin verlagert werden. Darüber hinaus besteht auch eine Ausgestaltung der Erfindung darin, dass das Polsterteil nach Entriegelung durch die Beaufschlagung eines Schwenkteils durch eine vorgespannte Torsionsfeder von der Ruhelage in die Wirklage verlagert wird, wobei hierbei von der Rückseite des Polsterteils ein Nocken absteht, der von einem Fortsatz des Schwenkteils beaufschlagt wird. Das Schwenkteil weist hierbei eine Schenkelfeder auf, welche einen Lagerbolzen umgibt, wobei an diesem eine den Fortsatz aufweisende Schwenkplatte drehfest angebracht ist, an der sich die Schenkelfeder mit Vorspannung abstützt. In der Schwenkplatte ist dabei eine bogenförmig um den Lagerbolzen verlaufende Formausnehmung mit mehreren im Abstand voneinander liegenden Rastvertiefungen ausgebildet, in die in unterschiedlichen Schwenklagen der Schwenkplatte ein an der Kopfstütze vorgesehener Arretierstift federbelastet einrastet (Merkmale der Patentansprüche 7 bis 10).The Padded part can after its unlocking via a sensor-controlled release element or The like by a longitudinally displaceable Device such as lifting cylinder, rack or the like, to the vehicle occupants be relocated. About that In addition, an embodiment of the invention is that the upholstery after unlocking by the application of a Swivel part by a prestressed torsion spring from the rest position is shifted to the original position, in this case from the back of the cushion part, a cam protrudes from an extension of the Pivoting part is acted upon. The pivoting part in this case has a leg spring on, which surrounds a bearing pin, wherein at this one the extension having rotating pivot plate is attached rotatably, at which the Leg spring with preload supported. In the swing plate is while an arcuate around the bearing pin extending mold recess with several at a distance formed locking depressions lying in the different pivoting positions the pivot plate provided on the headrest locking pin spring-loaded snaps (features of claims 7 to 10).
