Die Erfindung betrifft eine Vorrichtung der im Oberbegriff des Hauptanspruchs angegebenen Art.The invention relates to a device in the preamble of Main claim specified type.
Automatische Aufroller von Sicherheitsgurten besitzen in der Regel ein fahrzeugsensitives Blockier sy stern, das auf die Beschleunigungen des Fahrzeuges anspricht.Automatic seat belt retractors usually own a vehicle-sensitive locking system that reacts to the accelerations of the vehicle responds.
Bei Beschleunigungen, die einen genau definierten Grenzwert überschreiten, verlagert sich der Trägheitskörper, der ein Pendel oder eine Kugel sein kann, aus seiner Ruhelage und verschwenkt dabei die Sperrklinke. Die Sperrklinken spitze greift daraufhin in die Verzahnung des Sperrades ein, um somit die weitere Auszugsbewegung des Gurtes zu verhindern.In the case of accelerations that exceed a precisely defined limit value, the inertia body, which can be a pendulum or a ball, moves from its rest position and swivels in the process the pawl. The pawl tip then engages in the teeth of the ratchet wheel, thus allowing the further extension movement to prevent the belt.
Bei der Bewegung des Trägheitskörpers aus seiner Ruhelage kommt es nun durch das Anstoßen an die festen und starren Teile des den Trägheitskörper aufnehmenden Trägergehäuses zu unerwünschten Geräuschen.When the inertial body moves out of its rest position, it comes into contact with the solid and rigid parts of the den Inertia body receiving support housing to undesired noises.
Aufgabe der Erfindung ist es nun, durch einfache Maßnahmen diese Geräuschentwicklung erheblich zu reduzieren.The object of the invention is to reduce this noise development considerably by means of simple measures.
Die erfindungsgemäße Lösung ist anhand der Zeichnung erläutert. Die in der Zeichnung dargestellte fahrzeugsensitive Blockiervorrichtung ist an einem Schenkel des U-förmigen Gehäuses 1 des automatischen Aufrollers von Sicherheitsgurten befestigt. Das oberhalb der fahrzeugsensitiven Blockiervorrichtung drehbar gelagerte Sperrad 2 steuert direkt oder über ein Zwischenglied den entsprechenden Blockiermechanismus.The solution according to the invention is explained with reference to the drawing. The vehicle-sensitive locking device shown in the drawing is attached to one leg of the U-shaped housing 1 of the seat belt automatic retractor. The ratchet wheel 2 rotatably mounted above the vehicle-sensitive locking device controls the directly or via an intermediate member corresponding blocking mechanism.
Das Trägergehäuse 3 der fahrzeugsensitiven Blockiervorrichtung ist fest mit dem Gehäuse 1 verbunden und besteht aus hartem formstabilem Material.The carrier housing 3 of the vehicle-sensitive locking device is firmly connected to the housing 1 and consists of hard, dimensionally stable Material.

In einem Schenkel 4 des in der Regel U-förmigen Trägergehäuse a 3 befindet sich ein Schwenklager 5 für die Sperrklinke 6, die auf dem in der Abbildung als Kugel dargestellten Trägkeitskörper 7 aufliegt. Durch die Form des Trägheitskörpers 7 bedingt,, sind die Kontaktflächen 8 der Sperrklinke 6 mit dem Trägheitskörper 7 dachartig ausgebildet.In a leg 4 of the generally U-shaped support housing a 3 there is a pivot bearing 5 for the pawl 6, which is on the In the figure shown as a ball inertia body 7 rests. Due to the shape of the inertia body 7, the contact surfaces 8 of the pawl 6 with the inertia body 7 are like a roof educated.
Bei Verwendung eines Pendels oder Kegels als Trägheitskörper sind diese Kontaktflächen entsprechend der geänderten Geometrie geformt. Wie anhand der dargestellten Ausführungsform gut zu sehen ist, liegt die Kugel auf einem kalottenförmigen Einsatz 9 auf. Dieser Einsatz besteht aus einem elastischen Material, z. B. einem Elastomere, und ist in das form stabile Trägergehäuse 3 eingepreßt oder eingeklipst. Eine Zentrierung des Einsatzes 9 kann dabei z. B. durch einen angeformten Zapfen 10 erfolgen. Durch diesen elastischen Einsatz 9 wird sicher verhindert, daß die Kugel 7 bei ihrer Bewegung aus der Ruhelage an die harten Bereiche des Trägergehäuses 3 anstößt und unerwünschte Geräusche verursacht.When using a pendulum or cone as an inertial body, these contact surfaces are shaped according to the changed geometry. As can be clearly seen from the illustrated embodiment, lies the ball on a dome-shaped insert 9. This insert consists of an elastic material, e.g. B. an elastomer, and is pressed or clipped into the stable carrier housing 3. A centering of the insert 9 can, for. B. by an integrally formed pin 10. Through this elastic insert 9 it is reliably prevented that the ball 7 hits the hard areas of the support housing 3 when it moves out of the rest position causing unwanted noise.
IJine weitere Geräuschreduzierung wird erreicht, indem der ringförmige Außenrand 11 der dachartigen Auflageflächen 8 der Sperrklinke 6, sowie die Sperrklinkenspitze 12 ebenfalls mit einem elasti- ' sehen Einsatz bzw. Überzug versehen wird.IJine further noise reduction is achieved by using the ring-shaped Outer edge 11 of the roof-like bearing surfaces 8 of the pawl 6, as well as the pawl tip 12 also with an elastic ' see insert or coating is provided.
