Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Sicherheitsgurtsystem der gattungsgemäßen Art, eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, welche einen erhöhten konstruktiven Spielraum ermöglicht.The The present invention addresses the problem of for a safety belt system of the generic type Art, an improved or at least another embodiment specify which increased constructive margin allows.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, bei einem Sicherheitsgurtsystem in einem Kraftfahrzeug mit einem Gurtaufroller und einem Gurtstraffer, den Gurtstraffer als einzelne drehbare Rolle auszubilden, die ortsfest angeordnet ist und die von einem Gurtband derart durchdrungen ist, dass ein Drehen der Rolle ein Aufrollen und damit ein Straffen des Gurtbandes auf einer Mantelfläche der Rolle bewirkt. Gleichzeitig sind der Gurtaufroller und der Gurtstraffer an verschiedenen Orten in einer Sitzlehne eines Kraftfahrzeugsitzes angeordnet, wodurch dem Umstand Rechnung getragen werden kann, dass für eine aus Gurtaufroller und Gurtstraffer kombinierte Baueinheit üblicherweise mehr Bauraum erforderlich ist und dieser in modernen Kraftfahrzeugsitzen bzw. deren Lehnen normalerweise nicht zur Verfügung steht. Das Sicherheitsgurtsystem weist darüber hinaus ein Gurtband auf, welches mit einem Gurtendbeschlag an einem fahrzeugfesten bzw. einem sitzlehnenfesten Gurtanschlagpunkt befestigt und über ein oberes Umlenkelement, welches ebenfalls in der Sitzlehne integriert ist, umgelenkt ist. Zwischen dem Gurtendbeschlag und dem oberen Gurtumlenkelement, ist eine entlang des Gurtbandes verstellbare Gurtzunge vorgesehen, die in einem herkömmlichen Gurtschloss fixierbar ist. Der Gurtaufroller übernimmt die Aufgabe, das Gurtband im Nichtgebrauchsfall ordentlich zu verstauen, nämlich aufzurollen, während der Gurtstraffer die Aufgabe übernimmt, das Gurtband in Gefahrensituationen entgegen der Auszugsrichtung zu straffen. Durch die erfindungsgemäße Trennung des Gurtaufrollers und des Gurtstraffers sowie deren räumlich voneinander getrennte Anordnung in der Sitzlehne des Kraftfahrzeugsitzes, erfordert sowohl der Gurtaufroller als auch der Gurtstraffer für sich gesehen einen geringeren Bauraum, wodurch es möglich wird, den Gurtaufroller und insbesondere den Gurtstraffer an einem konstruktiv günstigen Punkt innerhalb der Sitzlehne anzuordnen. Im Vergleich zu aus dem Stand der Technik bekannten Lösungen, bei welchen der Gurtaufroller und der Gurtstraffer in einer kombinierten Baueinheit untergebracht waren, kann mit dem erfindungsgemäßen getrennt ausgebildeten Gurtaufroller und Gurtstraffer eine räumlich getrennte Anordnung dieser Aggregate erreicht werden, wodurch die ohnehin angespannte Bauraumsituation in der Sitzlehne eines Kraftfahrzeugsitzes deutlich entspannt werden kann.The The invention is based on the general idea of a safety belt system in a motor vehicle with a belt retractor and a belt tensioner, form the belt tensioner as a single rotatable roller, the stationary is arranged and which is so permeated by a webbing, that turning the reel will cause it to curl up and thereby tighten the reel Belt web causes on a lateral surface of the roller. simultaneously The belt retractor and the belt tensioner are in different locations arranged in a seat back of a motor vehicle seat, whereby account can be taken of the fact that for one From belt retractor and belt tensioner combined unit usually more space is required and this in modern motor vehicle seats or their backrests is not normally available. The seat belt system also has a webbing on, which with a Gurtendbeschlag to a vehicle-fixed or attached to a seat back belt stop point and over an upper deflector, which also integrated in the seat back is, is diverted. Between the belt end fitting and the upper belt deflection element, is provided along the webbing adjustable belt tongue, which is fixable in a conventional buckle. Of the Belt retractor takes over the task, the webbing when not in use neat to stow, namely to roll up while the belt tensioner takes over the task, the webbing in Tighten dangerous situations contrary to the direction of separation. By the separation of the belt retractor according to the invention and the belt tensioner and their spatially from each other separate arrangement in the seat back of the vehicle seat requires both the belt retractor and the belt tensioner for Seen a smaller space, making it possible is, the belt retractor and in particular the belt tensioner on a constructive to arrange favorable point within the seat back. in the Compared to solutions known from the prior art, in which the belt retractor and the belt tensioner in a combined unit were housed, can with the invention separately trained belt retractor and belt tensioner a spatially separate arrangement of these units can be achieved, whereby the already tense space situation in the seat back of a motor vehicle seat can be clearly relaxed.
Zweckmäßig ist die Rolle des Gurtstraffers als geschlitzte Rolle ausgebildet, durch deren Schlitz das Gurtband geführt ist. Selbstverständlich kann dabei die Rolle auch als Drehwalze ausgebildet sein, die einen quer durchgehenden Schlitz aufweist. Durch den Schlitz ist das Gurtband hindurch geführt. Sobald auf die Rolle ein Drehmoment einwirkt, wird das Gurtband in dem Schlitz gehalten und bei einer weiteren Verdrehung der Rolle, wickelt sich ein Teil des Gurtbandes auf den Mantel der Rolle auf, wodurch die Straffung des Gurtbandes erreicht wird. Die Rolle bewirkt dabei sowohl eine Sperrung als auch eine Straffung des Sicherheitsgurtes, wobei die Drehung entweder mittels eines mechanischen Antriebes oder durch einen elektromotorischen Antrieb erfolgen kann. Prinzipiell sind auch andere Antriebe, wie beispielsweise pneumatische oder hydraulische Antriebe einsetzbar. Alle Antriebe werden dabei vorzugsweise durch eine Sensoreinrichtung ausgelöst, die entweder ruckartige Belastungen auf das Gurtband überwacht oder eine Überwachung der Verzögerung des Kraftfahrzeuges vornimmt.Suitably, the role of the belt tensioner is designed as a slotted roller through the slot, the webbing is performed. Of course, the role may also be designed as a rotary roller having a transversely continuous slot. Through the slot, the webbing is passed. As soon as a torque acts on the roller, the belt is held in the slot and at a further rotation of the roll, a part of the webbing winds on the mantle of the roll, whereby the tightening of the webbing is achieved. The role causes both a blockage and a tightening of the seat belt, the rotation can be done either by means of a mechanical drive or by an electric motor drive. In principle, other drives, such as pneumatic or hydraulic drives can be used. All drives are preferably triggered by a sensor device which monitors either jerky loads on the webbing or makes a monitoring of the deceleration of the motor vehicle.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus der Zeichnung und aus der zugehörigen Figurenbeschreibung anhand der Zeichnung.Further important features and advantages of the invention will become apparent from the Subclaims, from the drawing and from the associated Description of the figures with reference to the drawing.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It it is understood that the above and the following yet to be explained features not only in each case specified combination, but also in other combinations or can be used in isolation, without the scope of the present To leave invention.
