Insassenrückhaltevorrichtung für ein Fahrzeug, insbesondere für ein Kraftfahrzeug, mit einem Sicherheitsgurt (4), einer Aufwickelvorrichtung (2) zum Aufwickeln des Sicherheitsgurtes (4), sowie einem Gurtstraffer mit einem mit der Aufwickelvorrichtung (2) koppelbaren elektromotorischen Antrieb (10, 16), wobei der Gurtstraffer einen pyrotechnischen Antrieb (32) umfasst, und die beiden Antriebe (32; 10, 16) wahlweise mit der Aufwickelvorrichtung (2) koppelbar sind, dadurch gekennzeichnet, dass der pyrotechnische Antrieb (32) über ein reversibles Stellglied (22) auf eine Aufwickelwelle (6) der Aufwickelvorrichtung (2) einwirkt, und dass zwischen der Aufwickelwelle (6) und dem Stellglied (22) eine Kupplung (40, 42, 44) angeordnet ist, die durch Druckgas aus dem pyrotechnischen Antrieb (32) einrückbar ist, wobei das Stellglied (22) pyrotechnisch oder elektromotorisch in die Ausgangsposition zurück bewegbar ist.Occupant restraint device for a vehicle, in particular for a motor vehicle, with a safety belt (4), a take-up device (2) for winding the seat belt (4), and a belt tensioner with an electromotive drive (10, 16) which can be coupled to the take-up device (2), wherein the belt tensioner comprises a pyrotechnic drive (32), and the two drives (32; 10, 16) can be selectively coupled to the take-up device (2), characterized in that the pyrotechnic drive (32) via a reversible actuator (22) a take-up shaft (6) of the take-up device (2) acts, and that between the take-up shaft (6) and the actuator (22) a clutch (40, 42, 44) is arranged, which by compressed gas from the pyrotechnic drive (32) is engageable , wherein the actuator (22) is pyrotechnic or electric motor movable back to the starting position.
Description
Die Erfindung betrifft eine Insassenrückhaltevorrichtung für ein Fahrzeug, insbesondere für ein Kraftfahrzeug, mit einem Sicherheitsgurt, einer Aufwickeleinrichtung zum Aufwickeln des Sicherheitsgurtes, sowie einem Gurtstraffer mit einem mit der Aufwickelelnrichtung koppelbaren elektromotorischen Antrieb.The invention relates to an occupant restraint device for a vehicle, in particular for a motor vehicle, with a safety belt, a winding device for winding the seat belt, and a belt tensioner with an electromotive drive which can be coupled to the take-up direction.
Zur Straffung von Sicherheitsgurten sind im Stand der Technik vor allem zwei Typen von Gurtstraffern bekannt, nämlich solche mit einem elektromotorischen Antrieb und solche mit einem pyrotechnischen Antrieb. Während der Vorteil von Gurtstraffern mit einem pyrotechnischen Antrieb vor allem in einer geringeren Ansprechzeit und einer auch für schwere. Fahrzeuginsassen ausreichenden größeren Rückhaltekraft besteht, ist die Gurtzugkraft von Gurtstraffern mit elektromotorischem Antrieb reversibel veränderbar und besser steuerbar, so dass es möglich ist, den Gurtstraffer nicht nur zum Straffen des Gurtes im Crashfall sondern auch zur Vorstraffung bei einer Vollbremsung sowie ggf. zur Einstellung einer nutzerdefinierten Gurtkraft zur Verbesserung des Tragekomforts im Fahrbetrieb zu benutzen.To streamline safety belts, two types of belt tensioners are known in the prior art, namely those with an electric motor drive and those with a pyrotechnic drive. While the advantage of belt tensioners with a pyrotechnic drive especially in a lower response time and also for heavy. Vehicle occupant sufficient greater retention force, the belt tension of belt tensioners with electric motor drive is reversibly changeable and better controllable, so that it is possible, the belt tensioner not only to tighten the belt in the event of a crash but also for pre-tightening in a full braking and possibly to set a user-defined Use belt force to improve wearing comfort while driving.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Insassenrückhaltevorrichtung der eingangsgenannten Art dahingehend zu verbessern, dass, sich die oben genannten Nachteile von Gurtstraffern mit pyrotechnischem bzw. elektromotorischem Antrieb vermeiden lassen.Proceeding from this, the present invention seeks to improve an occupant restraint device of the type mentioned in that, can avoid the above-mentioned disadvantages of belt tensioners with pyrotechnic or electric motor drive.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart. The object is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims.
Der erfindungsgemäße Gurtstraffer weist außer dem elektromotorischen Antrieb auch noch einen pyrotechnischen Antrieb auf, wobei die beiden Antriebe wahlweise mit der Aufwickelvorrichtung und vorzugsweise mit deren Aufwickelwelle koppelbar sind.The belt tensioner according to the invention, in addition to the electric motor drive on a pyrotechnic drive, wherein the two drives are selectively coupled to the take-up device and preferably with the take-up shaft.
Durch die erfindungsgemäße Merkmalskombination können die jeweiligen Vorteile eines elektromotorischen bzw. eines pyrotechnischen Antriebs ausgenutzt werden, indem der zuerst genannte Antrieb immer dann mit der Aufwickelwelle gekoppelt wird, wenn der Gurt mit einer verhältnismäßig geringen Zugkraft reversibel gestrafft werden soll, vor allem dann, wenn der Gurt in einer Pre-Crash-Situation, zum Beispiel bei einer Vollbremsung vorgestrafft werden soll, oder bei einem Crash nach einem ersten Aufprall zur Vorbeugung gegen einen nachfolgenden weiteren Aufprall eine beim ersten Aufprall ausgezogene Gurtlänge wieder aufgewickelt werden soll, um die Gurtlose aus dem System zu nehmen. Weiter kann der elektromotorische Antrieb ggf. verwendet werden, um während des Fahrbetriebs durch Einstellung einer steuerbaren Gurtzugkraft den Tragekomfort des Gurtes zu verbessern. Demgegenüber wird der zuletzt genannte pyrotechnische Antrieb nur im Fall einer tatsächlichen Crash-Situation mit der Aufwickelwelle gekoppelt, wenn eine große Rückhaltekraft mit geringer Zeitverzögerung bereitgestellt werden soll.By the combination of features according to the invention, the respective advantages of an electromotive or a pyrotechnic drive can be exploited by the first-mentioned drive is always coupled to the take-up shaft when the belt with a relatively low tensile force is to be tightened reversible, especially if the Belt in a pre-crash situation, for example, should be pre-tightened in a full braking, or in a crash after a first impact to prevent a subsequent further impact, a pulled out during the first impact belt length to be rewound to the belt slack from the system to take. Further, the electric motor drive may optionally be used to improve the comfort of the belt during driving by setting a controllable Gurtzugkraft. In contrast, the latter pyrotechnic drive is coupled only in the event of an actual crash situation with the take-up shaft, if a large retention force to be provided with a small time delay.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt eine Sicherheitsgurt-Aufwickeleinrichtung einer erfindungsgemäßen Insassenruckhaltevorrichtung mit einem Gurtstraffer, der einen pyrotechnischen und einen elektromotorischen Antrieb aufweist.In the following the invention will be explained in more detail with reference to an embodiment shown in the drawing.
