Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Aufnehmen von Energie für Rückhallceinrichiungen für Fahrzeuginsassen, insbesondere für Sicherheilsgurte mit einem Aufvsickelorgan für das kraftführende Teil, das gegenüber einem 1 laller verdrehbar isi und einem zwischen dem Halter und dem Aufwickelorgan angeordneten Drehstab nach Palen! 20 26 277.The invention relates to a device for absorbing energy for Rückhallceinrichiungen for Vehicle occupants, in particular for safety belts with a winding element for the force-carrying part, the compared to a 1 laller rotatable isi and a between the holder and the winding member arranged torsion bar according to Palen! 20 26 277.
Das llauptpatent befaßt sich mit tleni Problem, daß Rückhalteeinrichlungen für Fahrzeuginsasse-n wie Gurte oder Sitze beim Unfallstoß erhebliche Energiebeiriige aufnehmen müssen. Dabei dürfen die auf den Körper des Insassen einwirkenden Kriifte bestimmte Werte nicht überschreiten, wenn eine Verletzung ausgeschlossen werden soll.The main patent deals with the problem that Restraint devices for vehicle occupants such as belts or seats absorb considerable amounts of energy in the event of an accident have to. The forces acting on the occupant's body must not have certain values exceed if an injury is to be excluded.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so weiterzubilden, daß sie in konstruktiv einfacher Weise in einem selbstsperrenden Gurtaufroller verwendbar ist.The invention is based on the object of a device of the type mentioned in such a way that it can be used in a structurally simple manner in a self-locking manner Belt retractor can be used.
Diese Aufgabe wird gemiiß der vorliegenden Erfindung dadurch gelöst, daß das dem Halter zugeordnete Ende des Drehslabes mit einem drehbar gelagerten Sperrad drehfest verbunden ist, dem eine Sperrklinke zugeordnei ist, die bei einer vorbestimmten Verzögerung des Fahrzeuges das Sperrad starr mit dem Halter kuppelt. Auf diese Weise wird bei einer vorbestimmten Verzögerung des Fahrzeuges selbsttätig der mit dem Gurt verbundene Drehstab gesperrt und das Rückhaltesystem in Aktion gebracht, wobei ein Abziehen des Gurtes aus dieser Sperrstellung heraus nur durch Verdrehen d;s Drehslabes bei einer vorbestimmten Grenzkraft möglich ist.According to the present invention, this object is achieved in that the end of the rotary rod associated with the holder is connected in a rotationally fixed manner to a rotatably mounted ratchet wheel to which a ratchet pawl is assigned which rigidly couples the ratchet wheel to the holder when the vehicle is decelerated in a predetermined manner. In this way, the vehicle is automatically at a predetermined delay associated with the belt D r ehstab frozen and brought the restraint system in action, wherein a peeling of the belt d from this locking position out only by twisting; s Drehslabes at a predetermined boundary force is possible.
Gemäß einer Weiterbilduni; der Erfindung wird in vorteilhafter Weise eine automatische Sperrung dadurch bewirkt, daß zur Sperrung des Sperrades die trägheitsbedingte Relativbewegung einer Kugel vorgesehen ist. Diese Maßnahme ist an sich aus der US 32 37 729 bekannt.According to a training university; the invention becomes more advantageous Way an automatic locking caused by the fact that to lock the ratchet wheel the inertia Relative movement of a ball is provided. This measure is per se from US 32 37 729 known.
Eine konstruktive einfache Bauweise wird dadurch erreicht, daß die Sperrklinke gegen die Wirkung einer Feder verschwenkbur am Halter gelagert ist.A simple design is achieved in that the pawl against the action of a Spring is pivoted on the holder.
Die Erfindung wird anhand eines in der Zeichnung dargestellten Auslührungsbeispieles nachstehend erlaiilen. The invention is explained below on the basis of an exemplary embodiment shown in the drawing.
Fig. 1 und 2 zeigt eine sogenannte Gurtautomatik, an die ein Schuliergurtteil über einen Umlenkbeschlag in der bekannten An geführt wird. Eine Achse IS ist in diesem Fall links auf einem Vierkant eines Drehstabes 19. rechts in einem als Zahnrad ausgebildeten Sperrad 20 gelagert. Der Drehstab 19 seinerseits ist außen leicht drehbar im Halter 21 gelagert. Eine Spiralfeder 22 ist in einem Schiit/ der Achse 18 bzw. außen im Loch 23 der Hinicrwand des Halters 21 befestigt. Sie sorgt dafür, daß das Gurtband dauernd mit einer Krall von etwa 300 ρ auf die Achse 18 aufgewickelt wird Eine Scheibe 24 sorgt für eine Trennung /wischen der Spiralfeder 22 und dem Gurtband.Fig. 1 and 2 shows a so-called belt automatic a Schuliergurtteil is guided over a deflection fitting in the known to. An axis IS is in this Case on the left on a square of a torsion bar 19 on the right in a ratchet wheel 20 designed as a gear stored. The torsion bar 19, for its part, is mounted in the holder 21 so that it can easily be rotated on the outside. A coil spring 22 is in a Schiit / the axis 18 or outside in the hole 23 of the Hinicrwand of the holder 21 attached. She makes sure that the belt strap continuously with a claw of about 300 ρ the axle 18 is wound up. A disc 24 ensures a separation / wiping of the coil spring 22 and the webbing.
Unter tier Achse 18 liegt eine Sperrklinke 25, die rechts in Ausnehmungen des Halters 21. links auf einer Kugel 26 gelagert und durch eine Feder 27 in dieser Lage gehalten ist. Die Feder 27 ist auf die Masse der Kugel 26 so abgestimmt, daß eine bestimmte Ilorizontalbeschlcunigung (etwa 5 ni/sec"1) oder die Drehung des Erdbeschleunigungsveklors um mehr als 30" eine Relativbewegung der Kugel 26 /um Halter 21 hervorruft, was wiederum infolge der gewölbten Form der Sperrklinke 25 diese soweit anhebt, daß das Sperrad 20 durch ein- oder mehrere Nasen an der Sperrklinke 25 blockiert wird. Ein Herausziehen des Gurtes in diesem Zustand ist nur durch eine Verdrehung des Drchslabcs 19 möglich.Below tier axis 18 is a pawl 25 which is mounted on the right in recesses of the holder 21 on a ball 26 and held by a spring 27 in this position. The spring 27 is matched to the mass of the ball 26 so that a certain Ilorizontalbeschlcunigung (about 5 ni / sec " 1 ) or the rotation of the gravitational acceleration veklors by more than 30" causes a relative movement of the ball 26 / around the holder 21, which in turn results the arched shape of the pawl 25 raises it to such an extent that the ratchet wheel 20 is blocked by one or more lugs on the pawl 25. The belt can only be pulled out in this state by rotating the rotary tab 19.
