Abstract
Description
Die Erfindung betrifft einen selbstsperrenden Gurtaufroller nach dem Oberbegriff des Anspruchs 1.The The invention relates to a self-locking belt retractor after Preamble of claim 1.
Selbstsperrende Gurtaufroller sind in Sicherheitsgurtsystemen moderner Kraftfahrzeuge Standard. Solche selbstsperrenden Gurtaufroller weisen ein Gehäuse auf, in welchem die Spule, auf welchem das Gurtband aufgewickelt ist, gelagert ist. Die Spule ist mittels einer Spiralfeder gegen das Gehäuse vorgespannt, so dass nach Lösen des Sicherheitsgurtes die Gurtspule angetrieben wird und das Gurtband aufwickelt.Self locking Belt retractors are in safety belt systems of modern motor vehicles Default. Such self-locking belt retractors have a housing on which the spool on which the webbing is wound up is stored. The coil is by means of a coil spring against pretensioned the housing so that after loosening the Seat belt, the belt spool is driven and the webbing is wound up.
Da das Sicherheitsgurtsystem nur dann wirksam sein kann, wenn ein weiterer Auszug des Gurtes im Falle eines Unfalls unterbunden wird, müssen Maßnahmen getroffen werden, um dies zu erreichen. Bei den meisten Sicherheitsgurtsystemen wird dies dadurch erreicht, dass im Falle eines Unfalls die Gurtspule gegen das Gehäuse blockiert wird. Hierzu kann der selbstsperrende Gurtaufroller ein oder zwei Sensoren, nämlich einen sogenannten fahrzeugsensitiven Sensor und/oder einen sogenannten gurtsensitiven Sensor aufweisen. Der gurtsensitive Sensor wird dann aktiv, wenn das Gurtband mit einer Geschwindigkeit ausgezogen wird, die eine definierte Grenzgeschwindigkeit überschreitet. Der fahrzeugsensitive Sensor wird dann aktiv, wenn die Beschleunigung oder die Neigung des Kraftfahrzeugs einen vorbestimmten Wert übersteigt.There the seat belt system can only be effective if another Extraction of the belt in the event of an accident is prohibited, measures must be taken be taken to achieve this. For most safety belt systems This is achieved in that in the event of an accident, the belt reel is blocked against the housing. For this purpose, the self-locking Belt retractor one or two sensors, namely a so-called vehicle-sensitive sensor and / or a so-called belt-sensitive Have sensor. The belt-sensitive sensor becomes active when the webbing is pulled out at a speed that is a exceeds defined limit speed. The vehicle-sensitive Sensor then becomes active when the acceleration or the inclination of the motor vehicle exceeds a predetermined value.
Ein solcher fahrzeugsensitiver Sensor ist in der Regel mechanisch ausgebildet und kann beispielsweise eine in einer Kalotte gelagerte Kugel umfassen. Wird das Fahrzeug positiv oder negativ beschleunigt oder geneigt, so steigt die Kugel an der Wandung der Kalotte empor. Erreicht sie hierbei eine gewisse Höhe, so betätigt sie einen Hebelarm, welcher wiederum den Blockiermechanismus in Gang setzt Der Blockiermechanismus umfasst hierbei beispielsweise eine Steuerscheibe und eine Sperrklinke, welche in einen Profilkopf der Gurtspule eingreift und somit die Gurtspule gegen das Gehäuse blockiert.One Such vehicle-sensitive sensor is usually mechanically formed and may, for example, comprise a ball mounted in a dome. If the vehicle is accelerated positively or negatively or inclined, so the ball rises on the wall of the calotte. Achieve it Here a certain height, so she presses one Lever arm, which in turn sets the locking mechanism in motion The blocking mechanism here comprises, for example, a control disk and a pawl which engages in a profile head of the belt reel and thus blocking the belt reel against the housing.
Ein
solcher gattungsgemäßer selbstsperrender Gurtaufroller
ist beispielsweise in der
Die Sensor- und Blockiereinrichtung eines solchen selbstsperrenden Gurtaufrollers beinhaltet relativ viele bewegliche Teile. Da der selbstsperrende Gurtaufroller im fahrenden Kraftfahrzeug natürlich ständig Erschütterungen, Vibrationen und dergleichen ausgesetzt ist, sind diese beweglichen Teile Geräuschquellen, deren Geräuschemission von den Insassen, insbesondere vom Fahrer, zumindest als störend, häufig jedoch sogar als irritierend empfunden werden.The Sensor and blocking device of such a self-locking belt retractor includes relatively many moving parts. As the self-locking belt retractor in the moving motor vehicle, of course, constantly shaking, Vibrations and the like is exposed, these are mobile Parts of noise sources, their noise emission from the occupants, especially the driver, at least disturbing, However, they are often perceived as irritating.
Die
Hiervon ausgehend stellt sich die vorliegende Erfindung die Aufgabe, einen selbstsperrenden Gurtaufroller dahingehend zu verbessern, dass seine Geräuschemission minimiert ist.Of these, Based on the present invention, the task, a self-locking belt retractor to improve its noise emission is minimized.
Diese Aufgabe wird durch einen selbstsperrenden Gurtaufroller mit den Merkmalen des Anspruchs 1 gelöst.These Task is by a self-locking belt retractor with the Characteristics of claim 1 solved.
Die Grundidee der Erfindung besteht darin, für die Akustik des Systems wesentliche Bestandteile, so weit dies möglich ist, schwimmend bezüglich des Gehäuses zu befestigen. Hierdurch wird erreicht, dass die Schallübertragung von einem Bauteil auf ein anderes extrem reduziert wird. Für eine schwimmende Lagerung eignen sich insbesondere der fahrzeugsensitive Sensor und das Abdeckelement. Die Blockiermittel sind, da sie einerseits bezüglich des Profilkopfes sehr exakt positioniert sein müssen, und andererseits im Bedarfsfall sehr hohe Kräfte aufnehmen müssen, für eine schwimmende Befestigung in der Regel ungeeignet. Es werden deshalb vorzugsweise weitere Maßnahmen zur Geräuschunterdrückung ergriffen. Diese Maßnahmen beinhalten insbesondere die Unterdrückung von Resonanzen.The The basic idea of the invention is, for the acoustics of the system essential components, as far as possible is to fix floating with respect to the housing. This ensures that the sound transmission of one component to another is extremely reduced. For a floating storage are particularly suitable vehicle-sensitive Sensor and the cover. The blocking agents are, as they are on the one hand be positioned very accurately with respect to the profile head on the other hand, if necessary, very high forces for a floating attachment usually unsuitable. It will therefore be preferable Measures taken to suppress noise. These measures include in particular the suppression of resonances.
