Abstract
Description
Die Erfindung betrifft einen Fahrzeugsitz mit einem Sitzteil und einer mit diesem drehverbundenen Rückenlehne, welche an der Fahrzeugstruktur gelagert ist und deren Neigung bei einer Längsverlagerung des Sitzteils veränderbar ist, weiterhin mit zwischen Rückenlehne und Fahrzeugstruktur wirkenden Mitteln, welche alternativ eine Neigungsveränderung ohne Längsverlagerung des Sitzteils ermöglichen.The The invention relates to a vehicle seat with a seat part and a with this rotary-connected backrest, which is mounted on the vehicle structure and their inclination at a longitudinal displacement of the seat part changeable is, continue with between backrest and vehicle structure acting means, which alternatively a slope change without longitudinal displacement allow the seat part.
Ein
gattungsgemäßer Fahrzeugsitz
ist aus der Patentschrift
Darüber hinaus kann sich die Neigung der Rückenlehne infolge unfallbedingter Überlast auch unanhängig von einer Längsverstellung des Sitzteils dadurch verändern, dass die Kulisse gegenüber der Fahrzeugstruktur unter Torsion eines Querrohres nach vorne schwenkt. Die hierdurch ermöglichte, nach vorne gerichtete Drehbewegung der Rückenlehne wird dabei durch ein Fangband begrenzt. Durch diese Ausbildung soll die Verletzungsgefahr für den Sitzinsassen verringert werden.Furthermore may be the inclination of the backrest as a result of accidental overload also independent from a longitudinal adjustment of the seat part thereby changing, that the backdrop opposite the vehicle structure pivots forward under torsion of a cross tube. The thereby made possible, after Front-directed rotational movement of the backrest is doing through a tether limited. This training is intended to reduce the risk of injury to the seat occupant be reduced.
Ein
anderer Fahrzeugsitz mit Schlepplehne wird in der Offenlegungsschrift
Der Erfindung liegt die Aufgabe zugrunde, den Komfort vorbekannter Fahrzeugsitze zu verbessern.Of the Invention is based on the object, the comfort of previously known vehicle seats to improve.
Lösungsolution
Die Aufgabe wird bei einem gattungsgemäßen Fahrzeugsitz dadurch gelöst, dass die eingangs genannten Mittel zur Einstellung der Neigung der Rückenlehne geeignet sind. Der Sitzinsasse kann somit, ohne den Zwang einer Veränderung der Längsposition des Fahrzeugsitzes, verschiedene Neigungspositionen der Rückenlehne wählen. Die Vorteile, die eine Schlepplehne bietet, bleiben dennoch erhalten.The Task is solved in a generic vehicle seat in that the aforementioned means for adjusting the inclination of the backrest are suitable. The seat occupant can thus, without the compulsion of a change the longitudinal position of the vehicle seat, various inclination positions of the backrest choose. The advantages of a towing hitch are still preserved.
Die genannten Mittel zur unabhängigen Neigungsverstellung umfassen vorzugsweise einen an der Fahrzeugstruktur oder insbesondere im mittleren bis oberen Bereich der Rückenlehne angeordneten Drehantrieb oder eine Verriegelungseinrichtung mit einem gegenüber dieser schwenkbaren Hebel, welcher mit der Rückenlehne oder vorzugsweise mit der Fahrzeugstruktur wirkverbunden ist. Die bei einem Unfall auf die Mittel zur Neigungsverstellung wirkenden Belastungen sind dabei gegenüber einer unmittelbar im Gelenk zwischen Rückenlehne und Sitzteil angeordneten Einstelleinrichtung (Recliner) relativ gering.The referred to independent funds Tilt adjustment preferably includes one on the vehicle structure or in particular in the middle to upper region of the backrest arranged rotary drive or a locking device with a across from this pivotable lever, which with the backrest or preferably is operatively connected to the vehicle structure. The one in an accident are on the means for tilt adjustment loads acting opposite a arranged directly in the joint between the backrest and seat part Recliner relatively low.
Dieser Hebel kann beispielsweise an seinem freien Ende mit einem Gelenkarm drehbar verbunden werden, der seinerseits schwenkbar an der Rückenlehne oder insbesondere an der Fahrzeugstruktur angelenkt ist. Das nicht sperrbare Gelenk zwischen Rückenlehne und Sitzteil, die Drehachse des Drehantriebs oder der Verrieglungseinrichtung sowie die beiden Gelenke des Gelenkarms bilden somit einen Viergelenkmechanismus aus, wobei eine Verstellung des Drehantriebs oder der Verriegelungseinrichtung den Winkel zwischen Gelenkarm und Hebel verändert und damit die Rückenlehne nach vorne oder hinten verlagert.This Lever can, for example, at its free end with an articulated arm be rotatably connected, in turn pivotally mounted on the backrest or in particular is articulated to the vehicle structure. Not that one lockable joint between backrest and seat part, the axis of rotation of the rotary drive or the Verrieglungseinrichtung as well as the two joints of the articulated arm thus form a four-bar linkage mechanism from, wherein an adjustment of the rotary drive or the locking device the Angle between articulated arm and lever changed and thus the backrest shifted to the front or back.
Alternativ kann der Hebel an seinem freien Ende in einer an der Rückenlehne oder insbesondere an der Fahrzeugstruktur angeordneten, beispielsweise vertikalen Kulisse geführt werden.alternative The lever can be at its free end in one on the backrest or in particular arranged on the vehicle structure, for example vertical backdrop led become.
Der
Drehantrieb umfasst mit Vorteil ein Exzentergetriebe (Taumelgetriebe).
Ein geeignetes Getriebe ist zum Beispiel aus der Druckschrift
Eine zur Durchführung der Erfindung brauchbare Verriegelungseinrichtung wird beispielsweise in der deutschen Patentanmeldung 10 2004 047 420.6 beschrieben. Um die Betätigung der Neigungseinstellung zu erleichtern, sind bei der Verwendung einer Verriegelungseinrichtung mit Vorteil die Rückenlehne um das Gelenk in Richtung des Sitzinsassen vorspannende Federmittel vorgesehen.A to carry out For example, the locking device useful in the invention in German Patent Application 10 2004 047 420.6. To the actuation to facilitate the tilt adjustment are in use a locking device with advantage the backrest around the hinge in Direction of the seat occupant biasing spring means provided.
Alternativ können die Mittel einen zwischen Fahrzeugstruktur und Rückenlehne wirkenden Linearantrieb umfassen, der beispielsweise als Spindelgetriebe ausgebildet ist.Alternatively, the means may be an acting between vehicle structure and backrest linea include drive, which is formed for example as a spindle gear.
Dreh- oder Linearantrieb können grundsätzlich auch manuell betätigt werden, die Verstellung erfolgt jedoch vorzugsweise elektrisch. Ebenso wird die Längsverstellung des Sitzteils mit Vorteil durch einen elektrischen Antrieb bewirkt.rotary or linear drive can in principle also manually operated However, the adjustment is preferably carried out electrically. Likewise, the longitudinal adjustment the seat part is advantageously effected by an electric drive.
