Description
Die vorliegende Erfindung betrifft ein Sicherheitssystem in einem Fahrzeug, mit einem Umlenksystem, das einen Umlenkbeschlag zur Führung eines Sicherheitsgurtes aufweist.The The present invention relates to a safety system in a vehicle, with a deflection system that has a deflection fitting for guiding a Seat belt has.
Es ist aus dem Stand der Technik bekannt, Sensoren zur Gurtkraftmessung am Endbeschlag vorzusehen. Die im angegurteten Zustand eines Fahrzeuginsassen im Gurtband wirkende Kraft kann Aufschluß über den jeweiligen Fahrzustand geben. Es kann beispielsweise anhand der ermittelten Gurtbandkraft eine Notfallsituation erkannt werden und daraufhin ein elektronisch ansteuerbarer Gurtaufroller so angesteuert werden, daß das Gurtband gestrafft wird. Auch die Aktivierung eines Gassacks zum Schutz des Fahrzeuginsassen kann in Abhängigkeit der ermittelten Gurtbandkraft gesteuert werden.It is known from the prior art, sensors for belt force measurement to provide at the end fitting. The belted state of a vehicle occupant The force acting in the webbing can provide information about the respective driving condition give. It can, for example, based on the determined Gurtbandkraft an emergency situation are detected and then an electronic controllable belt retractor are controlled so that the webbing is streamlined. Also, the activation of a gas bag to protect the Vehicle occupants may depend on the determined Gurtbandkraft be controlled.
Die vorliegende Erfindung stellt ein Sicherheitssystem in einem Fahrzeug bereit, durch das auf einfache Weise die im Gurtband wirkende Zugkraft ermittelt werden kann.The The present invention provides a safety system in a vehicle ready, determined by the simple acting on the webbing tension can be.
Gemäß der vorliegenden Erfindung weist das Umlenksystem einen Kraftsensor und ein Widerlager für den Kraftsensor auf, wobei der Umlenkbeschlag auf einem mit einem fahrzeugfesten Bauteil verbundenen Befestigungsbolzen drehbar befestigt ist und so mit dem Kraftsensor gekoppelt ist, daß eine am Umlenkbeschlag in Richtung der Mittelachse des Befestigungsbolzens wirkende Kraftkomponente auf den Kraftsensor übertragen werden kann. Durch die auf den Kraftsensor übertragene Kraftkomponente kann unmittelbar auf die im Gurtband wirkende Zugkraft geschlossen werden. Die Gurtkraftmessung mittels des Umlenksystems gemäß der vorliegenden Erfindung beeinträchtigt in keinster Weise den Gebrauch und/oder die Rückhaltefunktion des Gurtbands und läßt sich mit wenigen zusätzlichen Bauteilen realisieren. Aufwendige Vorrichtungen am Gurtband zur Messung der Gurtkraft, wie beispielsweise aus der WO 99/29539 bekannt ist, sind überflüssig geworden.According to the present Invention, the deflection system includes a force sensor and an abutment for the Force sensor, wherein the deflection fitting on a vehicle with a fixed Component connected fastening bolt is rotatably mounted and is coupled to the force sensor, that at the deflection fitting in Direction of the central axis of the fastening bolt acting force component transferred to the force sensor can be. By transmitted to the force sensor force component can be closed directly to the tensile force acting in the webbing. The belt force measurement by means of the deflection system according to the present Invention impaired in no way the use and / or the retention function of the webbing and lets himself go with a few extra Realize components. Elaborate devices on the webbing for Measurement of the belt force, as known for example from WO 99/29539 is become redundant.
Gemäß einer bevorzugten Variante ist der Kraftsensor so ausgebildet, daß ein mit einer Drehung des Umlenkbeschlags variierendes Signal erzeugt wird. Dadurch ist es möglich, zusätzlich zu dem Betrag der in dem Gurtband wirkenden Zugkraft die Richtung der im Gurtband wirkenden Zugkraft bzw. den Abzugswinkel des Gurtbandes zu bestimmen.According to one preferred variant, the force sensor is designed so that a with a rotation of the deflection fitting varying signal is generated. This makes it possible additionally to the amount of tensile force acting in the webbing the direction the tensile force acting in the webbing or the deduction angle of the webbing to determine.
Gemäß einer besonders bevorzugten Variante umfaßt dazu der Kraftsensor mehrere Sensorelemente, die rotationssymmetrisch bezüglich der Mittelachse des Befestigungsbolzens angeordnet sind. Der Kraftsensor ist fahrzeugfest angeordnet. Bei einer solchen Anordnung ändern sich mit einer Drehung des Umlenkbeschlags um die Mittelachse des Befestigungsbolzens die an den einzelnen drucksensitiven Sensorelementen erzeugten Signale relativ zueinander. Da sich bei einer Änderung des Gurtbandabzugswinkels der Umlenkbeschlag um die Mittelachse des Befestigungsbolzens dreht, kann eine bestimmte Druckverteilung an den einzelnen Sensorelementen einem bestimmten Gurtbandabzugswinkel zugeordnet werden.According to one Particularly preferred variant, the force sensor comprises several Sensor elements which are rotationally symmetrical with respect to the central axis of the fastening bolt are arranged. The force sensor is arranged fixed to the vehicle. at change such an arrangement with a rotation of the deflection fitting about the central axis of the fastening bolt the signals generated at the individual pressure-sensitive sensor elements relative to each other. As with a change in the webbing withdrawal angle the deflection fitting rotates about the center axis of the fastening bolt, can be a certain pressure distribution on the individual sensor elements be assigned to a specific Gurtbandabzugswinkel.
Bevorzugterweise ist eine elektronische Steuereinheit vorgesehen, die eine Eingangsschnittstelle für am Kraftsensor erzeugte Signale aufweist. Die elektronische Steuereinheit kann dazu vorgesehen sein, eine Gurtband-Höhenverstellvorrichtung anzusteuern, um das Umlenksystem in Richtung der Fahrzeughöhe zu verschieben, so daß das Gurtband im Schulterbereich des Fahrzeuginsassen unter einem vorgegebenen Winkel verläuft, der einen optimalen Rückhalt des Fahrzeuginsassen gewährleistet. Durch die Höhenverstellung kann das Umlenksystem an individuelle Parameter wie die Körpergröße des Fahrzeuginsassen bzw. die Sitzposition des Fahrzeuginsassen angepaßt werden.preferably, an electronic control unit is provided which has an input interface for am Force sensor has generated signals. The electronic control unit may be intended to control a webbing height adjustment device, to move the deflection system in the direction of the vehicle height, so that the webbing in the Shoulder area of the vehicle occupant at a predetermined angle runs, the optimal support ensured by the vehicle occupant. By the height adjustment The deflection system can adapt to individual parameters such as the height of the vehicle occupant or the seating position of the vehicle occupant to be adjusted.
Zusätzlich oder alternativ dazu kann die elektronische Steuereinheit in Abhängigkeit von am Kraftsensor erzeugten Signalen einen Gurtaufroller ansteuern, um die Gurtbandkraft an den jeweiligen Betriebszustand des Fahrzeugs anzupassen. Im Notfall kann die Steuereinheit den Gurtaufroller so ansteuern, daß die Gurtspule in Gurtbandaufwickelrichtung angetrieben wird. So kann ein Notfall durch einen plötzlichen Anstieg der im Gurtband wirkenden Zugkraft, aber auch durch eine plötzliche Änderung des Gurtbandabzugswinkels, bedingt durch die Vorverlagerung des Fahrzeuginsassen, erkannt werden.Additionally or alternatively, the electronic control unit may be dependent triggering a belt retractor from signals generated by the force sensor, to the Gurtbandkraft to the respective operating condition of the vehicle adapt. In an emergency, the control unit can the belt retractor so drive that the Belt spool is driven in Gurtbandaufwickelrichtung. So can an emergency by a sudden Increase in the tension acting in the webbing, but also by a sudden change the webbing withdrawal angle, due to the forward displacement of the Vehicle occupants are recognized.
