Abstract
Description
Die Erfindung betrifft einen Fahrzeugsitz, insbesondere für einen Kraftwagen, der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The The invention relates to a vehicle seat, in particular for a vehicle Motor vehicle specified in the preamble of claim 1 Art.
Ein
solcher Fahrzeugsitz ist beispielsweise bereits aus der
Als nachteilig bei diesem bekannten Fahrzeugsitz ist der Umstand anzusehen, dass das infolge einer unfallbedingten Rückbewegung des Sitzinsassen erfolgende Absenken des Sitzkissens mit seinem vorderen Ende zu einer unerwünschten Position des Sitzinsassen führt, welche beispielsweise den so genannten Submarining-Effekt begünstigt, bei welchem der Sitzinsasse im weiteren Verlauf des Unfallszenarios bei einer Vorwärtsbewegung unter dem Sicherheitsgurt hindurchrutschen kann.When disadvantageous in this known vehicle seat is the circumstance, that due to an accidental return movement of the seat occupant Successful lowering of the seat cushion with its front end to an undesirable Position of the seat occupant leads, which favors, for example, the so-called submarining effect, at which the seat occupant in the further course of the accident scenario during a forward movement can slip under the seat belt.
Aufgabe der vorliegenden Erfindung ist es daher, einen Fahrzeugsitz der eingangs genannten Art zu schaffen, mit welchem der Sitzinsasse bei einer unfallbedingten Rückbewegung auf verbesserte Weise vor Verletzungen geschützt ist.task The present invention is therefore a vehicle seat of to create the aforementioned type, with which the seat occupant in an accidental return movement is protected from injury in an improved way.
Diese Aufgabe wird erfindungsgemäß durch einen Fahrzeugsitz mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Patentansprüchen angegeben.These The object is achieved by a Vehicle seat solved with the features of claim 1. advantageous Embodiments with appropriate and Non-trivial developments of the invention are specified in the remaining claims.
Um bei einer unfallbedingten Rückbewegung des Sitzinsassen dessen Verletzungsrisiko weiter reduzieren zu können, ist es erfindungsgemäß vorgesehen, dass die Rückenlehne über eine Mehrgelenk-Anordnung am Sitzgestell gehalten und bei einer unfallbedingten Rückbewegung des Sitzinsassen relativ zu dem Sitzgestell bewegbar ist. Mit anderen Worten ist es mit dem erfindungsgemäßen Fahrzeugsitz möglich, insbesondere bei einem Heckaufprall auf den Kraftwagen und einer damit einhergehenden Rückbewegung des Sitzinsassen in Fahrzeuglängsrichtung nach hinten dessen Verletzungsrisiko dadurch zu minimieren, dass das obere Ende der Rückenlehne mittels der Mehrgelenk-Anordnung in eine vorverlagerte Position bewegt wird. Hierdurch wird eine bessere Abstützung des Kopfes durch eine am oberen Ende der Rückenlehne angeordnete Kopfstütze sowie eine bessere Abstützung des Oberkörpers des Insassen erreicht, indem das obere Ende der Rückenlehne entsprechend nach vorne bewegt wird, um den Abstand zum oberen Bereich des Rückens bzw. des Kopfes des Sitzinsassen zu verringern. Bei der unfallbedingten Rückbewegung des Sitzinsassen trifft dieser somit frühzeitig auf die Kopfstütze bzw. den oberen Bereich der Rückenlehne auf, so dass sich infolge der unfallbedingten Rückbewegung für den Sitzinsassen weitaus geringere Beschleunigungswerte ergeben, als dies der Fall wäre, wenn der obere Bereich der Rückenlehne nicht nach vorne verlagert werden würde. Im Ergebnis können somit insbesondere Verletzungen im Bereich des Rückens, der Halswirbelsäule oder des Kopfes des Sitzinsassen, wie beispielsweise so genannte Peitschenverletzungen oder Schleudertraumata, verhindert werden.Around in an accidental return movement of the Seat occupants whose injury risk can be further reduced, is it is provided according to the invention that the backrest over a Multi-joint arrangement held on the seat frame and in an accidental return movement the seat occupant is movable relative to the seat frame. In other words it is with the vehicle seat according to the invention possible, especially in a rear impact on the car and a associated return movement of the seat occupant in the vehicle longitudinal direction back to minimize its risk of injury by that the upper end of the backrest by means of the multi-joint arrangement in a vorverlagerte position is moved. As a result, a better support of the head by a at the upper end of the backrest arranged headrest as well as a better support of the upper body of the occupant reached by the upper end of the backrest is moved forward accordingly to the distance to the upper area of the back or the head of the seat occupant. In the case of accident return movement of the seat occupant thus meets early on the headrest or the upper part of the backrest on, so that as a result of the accidental return movement for the seat occupant much lower acceleration values than is the case would be if the upper part of the backrest would not be moved forward. As a result, can thus in particular injuries in the area of the back, the cervical spine or the head of the seat occupant, such as so-called whiplash injuries or whiplash, to be prevented.
Da
die Rückenlehne über die
Mehrgelenk-Anordnung relativ zu dem Sitzgestell bewegbar ist, wird
diese bei einer unfallbedingten Rückbewegung des Sitzinsassen
mit ihrem unteren Ende in eine rückverlagerte
und mit ihrem oberen Ende in eine vorverlagerte Position relativ
zu dem Sitzuntergestell gebracht. Das Sitzuntergestell selbst muss dabei
im Unterschied zum Stand der Technik gemäß
In weiterer Ausgestaltung der Erfindung hat es sich darüber hinaus als vorteilhaft gezeigt, wenn die Mehrgelenk-Anordnung wenigstens eine Viergelenk-Anordnung umfasst. Dabei wäre es natürlich auch denkbar, auf beiden Seiten des Fahrzeugsitzes jeweils eine separate Viergelenk-Anordnung vorzusehen.In further embodiment of the invention, it has moreover shown as advantageous when the multi-joint arrangement at least a four-joint arrangement comprises. It would of course be conceivable on both Pages of the vehicle seat each have a separate four-bar arrangement provided.
Eine besonders einfache Halterung der Rückenlehne an dem Sitzgestell kann geschaffen werden, wenn ein Gelenkstab der Mehrgelenk-Anordnung fest mit der Rückenlehne verbunden ist. Dieser wenigstens eine Gelenkstab ist vorzugsweise am unteren Ende der Rückenlehne angeordnet und steht in Richtung des Sitzgestells von der Rückenlehne nach vorne hin ab. Hierdurch kann auf einfache Weise eine Mehrgelenk-Anordnung geschaffen werden, welche im Wesentlichen bauraumsparend unterhalb des Sitzgestells angeordnet ist.A particularly simple mounting of the backrest on the seat frame can be created when a joint rod of the multi-joint arrangement is firmly connected to the backrest. This at least one joint rod is preferably arranged at the lower end of the backrest and projects in the direction of the seat frame from the backrest towards the front. In this way, a multi-joint arrangement can be created in a simple manner, which substantially saves space below the Seat frame is arranged.
Eine besonders einfach ausgebildete Mehrgelenk- bzw. Viergelenk-Anordnung ist geschaffen, wenn der am unteren Ende der Rückenlehne vorgesehene Gelenkstab über zwei Koppelstäbe gelenkig mit dem Sitzgestell verbunden ist. Um die erwünschte Bewegung der Rückenlehne im Falle einer unfallbedingten Rückbewegung des Sitzinsassen zu erreichen, sind die beiden Koppelstäbe dabei in einer besonders bevorzugten Ausführungsform in unterschiedlichen Längen ausgebildet.A Particularly simple trained Mehrgelenk- or four-joint arrangement is created when provided at the lower end of the backrest joint rod over two coupling rods hinged to the seat frame is connected. To the desired movement the backrest in the event of an accidental return To reach the seat occupant, the two coupling rods are there in a particularly preferred embodiment in different lengths educated.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung. Diese zeigt eine schematische Seitenansicht auf einen Fahrzeugsitz eines Personenkraftwagens, dessen Rückenlehne über eine Mehrgelenk-Anordnung am Sitzgestell festgelegt ist.Further Advantages, features and details of the invention will become apparent the following description of a preferred embodiment as well as the drawing. This shows a schematic side view on a vehicle seat of a passenger car whose backrest over a Multi-joint arrangement is fixed to the seat frame.
