Abstract

In order, in the case of a locking device for the belt of an automatic belt retraction device which is assigned to a reclining seat part in a motor vehicle and has a locking lever which is actuated by means of a weight which can be extended, to prevent displacement of the locking lever during the restoring movement which is necessary when the inclination of the seat part is changed, the locking lever is mounted in a known fashion so as to be fixed on the roller side and a supporting body which has at least one spherical section is arranged between the locking lever and a control element which has a conical control path. The pivot axis of the rolling surface assigned to the said supporting body and the pivot axis of the control element coincide during a restoring movement caused by a change in the inclination of the seat part.

Description

Die Erfindung betrifft eine Sperreinrichtung für das Gurtband eines einem neigungsveränderbaren Sitzteil in einem Kraftwagen zugeordneten Gurtrollautomaten mit einem durch eine auslenkbare Masse betätigbaren Rast­ hebel, wobei eine die auslenkbare Masse abstützende Aufnahme am Gehäuse des Gurtrollautomaten gelagert ist und entsprechend der durchgeführten Neigungsänderung rückgestellt wird.The invention relates to a locking device for the Webbing of an inclinable seat part in a belt reel assigned to a motor vehicle a latch that can be actuated by a deflectable mass lever, one supporting the deflectable mass Mounted on the housing of the automatic belt reel and according to the change in inclination performed is reset.

Eine derartige Sperreinrichtung ist durch die DE-OS 34 10 297 bekannt, wobei durch eine aufwendige, einen großen Bauraum beanspruchende Hebelanordnung erreicht wird, daß bei der Durchführung einer Schwenkbewegung zur Ausrichtung der Sperreinrichtung bei einem einher­ gehenden Verschwenken des Gurtrollautomaten die Sperr­ klinke am freien Ende des Rasthebels nahezu ortsfest bleibt, damit im Ansprechfall ein sicheres Einrasten in die zugeordnete Zahnlücke des Klinkenrades erfolgt.Such a locking device is through the DE-OS 34 10 297 known, with a complex, a large space requirement lever arrangement reached will that when performing a swivel motion to align the locking device with one hand pivotal movement of the automatic belt reel the locking device jack at the free end of the locking lever almost stationary remains so that it engages securely when activated into the assigned tooth space of the ratchet wheel.

Aufgabe der Erfindung ist es, die Sperreinrichtung so auszubilden, daß selbst bei großen Ausrichtbewegungen keine Lageveränderung des Rasthebels und somit der Sperr­ klinke auftritt.The object of the invention is the locking device so train that even with large alignment movements no change in position of the locking lever and thus the lock jack occurs.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.This task is characterized by the characteristics of the Claim 1 solved.

Ein besonders einfacher Aufbau ergibt sich, wenn der Stütz­ körper aus einer die auslenkbare Masse bildenden Kugel be­ steht, die ihrerseits auf der gleichzeitig als Steuerglied fungierenden Aufnahme ruht.A particularly simple structure results when the support body from a ball forming the deflectable mass stands, which in turn is on the same as a control link acting recording rests.

Es ist aber auch möglich, daß das Steuerglied die auslenk­ bare Masse bildet und diese randseitig kippbar in der Auf­ nahme ruht.But it is also possible for the control element to deflect the forms a clear mass and the edge can be tilted in the opening name rests.

Drei Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung näher erläutert. Es zeigtThree embodiments of the invention are as follows explained in more detail with reference to the drawing. It shows

Fig. 1 eine erste, ohne das rollerseitige Klinken­ rad dargestellte Sperreinrichtung mit einer Kugel als auslenkbare Masse, Fig. 1 shows a first, without the roller-side latches wheel blocking device shown with a ball as a deflectable mass,

Fig. 2 eine Anordnung gemäß Fig. 1, bei der die auslenkbare Masse die Form einer Tonne auf­ weist, und Fig. 2 shows an arrangement according to FIG. 1, in which the deflectable mass has the shape of a ton, and

Fig. 3 eine weitere Anordnung gemäß den vorstehenden Figuren mit pendelartig auslenkbarer Masse. Fig. 3 shows a further arrangement according to the preceding figures with a pendulum-like deflectable mass.

Gehäuseseitig eines nicht dargestellten Gurtrollautomaten ist ein Rasthebel 1 mit einer an seinem freien Ende ge­ legenen Sperrklinke 2 sowie ein Steuerglied 3 schwenkbar gelagert. Mit letzterem ist ein Stellhebel 4 gelenkig verbunden, über den - hervorgerufen durch eine nicht gezeigte Stelleinrichtung - eine Kompensation der beim Verschwenken des dem Gurtrollautomaten zugeordneten Sitzteiles, z.B. der Rückenlehne, eintretenden Aus­ lenklage einer ab bestimmten Fahrzeugverzögerungen und Fahrzeugschräglagen auslenkbaren, einem Gurtauszug durch Einrasten der Sperrklinke 2 in ein rollenseitig zugeordnetes, nicht dargestelltes Klinkenrad verhin­ dernden Masse erfolgt, die als Kugel 5 (Fig. 1), als Tonne 6 (Fig. 2) oder als Pendel 7 (Fig. 3) ausgebildet ist.On the housing side of a belt retractor, not shown, a locking lever 1 with a ge at its free end pawl 2 and a control member 3 is pivotally mounted. With the latter, an adjusting lever 4 is articulated, via which - caused by an adjusting device ( not shown) - compensation of the swiveling of the seat part assigned to the automatic belt reel, for example the backrest, from the steering position of a deflectable position from certain vehicle decelerations and vehicle inclinations, a belt pull-out by engaging the Pawl 2 in a roller-side associated, not shown ratchet-preventing mass takes place, which is designed as a ball 5 ( Fig. 1), as a barrel 6 ( Fig. 2) or as a pendulum 7 ( Fig. 3).

Zwischen dem Rasthebel 1 und dem Steuerglied 3, das gemäß den Fig. 2 und 3 von der auslenkbaren Masse selbst ge­ bildet wird und das eine trichterförmige Steuerbahn 8 auf­ weist, ist ein Stützkörper 9 angeordnet, der zumindest in seinem der Steuerbahn 8 zugekehrten Bereich mit einem Kugelabschnitt 10 versehen ist. Der Stützkörper 9 wird beim Ausführungsbeispiel nach Fig. 1 von der Kugel 5 gebildet, während er bei den Ausgestaltungsvarianten nach den Fig. 2 und 3 fest am Rasthebel 1 angeordnet ist.Between the locking lever 1 and the control member 3 , which forms itself according to FIGS . 2 and 3 of the deflectable mass itself and which has a funnel-shaped control track 8 , a support body 9 is arranged, at least in its area facing the control track 8 with a spherical section 10 is provided. The support body 9 is formed in the embodiment according to FIG. 1 by the ball 5 , while in the embodiment variants according to FIGS . 2 and 3 it is fixedly arranged on the locking lever 1 .

Um bei einer über den Stellhebel 4 eingeleiteten Schwenk­ bewegung eine Lageveränderung des Rasthebels 1 und damit eine Positionsveränderung der Sperrklinke 2 zu verhindern, fällt jeweils die der wirksamen Gleitbahn des Kugelab­ schnittes 10 zugeordnete Schwenkachse mit der Schwenk­ achse des Steuergliedes 3, bzw. mit einer dieses ab­ stützenden Aufnahme 11 (Fig. 2 und 3), wie durch die gemeinsame Positionsbezeichnung 12 hervorgehoben, zu­ sammen.In order to prevent a change in position of the locking lever 1 and thus a change in position of the pawl 2 in a pivoting movement initiated via the adjusting lever 4 , the effective slideway of the Kugelab section 10 associated with the pivot axis of the pivot member of the control member 3 , or with one of these from supportive recording 11 ( Fig. 2 and 3), as highlighted by the common position designation 12 together.

Erfolgt eine starke Fahrzeugverzögerung oder kommt das Fahrzeug in eine ungewöhnliche Schräglage, so erfolgt beim Ausführungsbeispiel nach Fig. 1 eine Auslenkung der Kugel 5, die dabei auf der Steuerbahn 8 nach oben läuft, während bei den Ausgestaltungsvarianten nach den Fig. 2 und 3 eine Kippbewegung der Tonne 6 und des Pendels 7 einsetzt. Jede dieser Bewegungen führt zu einer Aufwärtsbewegung des Rasthebels 1, so daß es in nicht dargestellter Weise zu einem sperrenden Ein­ griff der jeweiligen Sperrklinke 2 kommt.If there is a strong deceleration of the vehicle or if the vehicle comes into an unusual inclined position, in the exemplary embodiment according to FIG. 1 the ball 5 is deflected , which runs upwards on the control track 8 , while in the variant embodiments according to FIGS. 2 and 3 there is a tilting movement the barrel 6 and the pendulum 7 begins. Each of these movements leads to an upward movement of the locking lever 1 , so that it comes to a locking A handle of the respective pawl 2 in a manner not shown.
