Abstract

The clasp (10) of the safety belt is retained in the catch housing by a hinged retaining catch (16) whose inner end is held in the locked position by a spring-loaded slider catch (20). The coil spring (30) for the retaining catch has one end located over a short tag (35) on the hinged catch. The spring is aligned inside a guide duct formed by flanges attached to the inside of the catch housing (14). The catch is released via a release tab (24) on the side of the catch housing. The slider end of the spring has a wider-diameter section (40) which aligns centrally between the guide tags. The widened end has close spaced windings shaped into a flattened end flange.

Description

Die Erfindung bezieht sich auf einen Verschluß für Sicherheitsgurte, mit einem Schwenkriegel, der in einem lasttragenden Rahmen gelagert ist und in seiner Sperrstellung an einer Rastkante einer Steckzunge angreift, einem Sperrglied, das am Rahmen quer zur Schwenkrichtung des Schwenkriegels zwischen einer Öffnungsstellung, in der es den Schwenkriegel freigibt, und einer Sperrstellung, in der es den Schwenkriegel in seiner Eingriffsstellung blockiert, verschiebbar gelagert ist, einer gleichfalls am Rahmen gelagerten Lösetaste, durch deren Betätigung das Sperrglied in die Öffnungsstellung verschiebbar ist, und einer schraubenförmigen Druckfeder, die sich mit ihrem einen Ende an dem Schwenkriegel und mit ihrem anderen Ende an dem Sperrglied abstützt sowie in einer Federaufnahme gehalten ist, die von Zwei Stegen des Rahmens begrenzt ist und einen Zapfen am Sperrglied umfaßt.The invention relates to a buckle for seat belts, with a pivot bolt which is mounted in a load-bearing frame and engages in its locking position on a locking edge of a tongue, a locking member which is on the frame transversely to the pivoting direction of the pivot bolt between an open position in which it releases the swivel bolt, and a locking position in which it blocks the swivel bolt in its engaged position, is mounted displaceably, a release button also mounted on the frame, the actuation of which moves the locking member into the open position, and a helical compression spring, which is in contact with one of them End is supported on the swivel bolt and with its other end on the locking member and is held in a spring receptacle which is delimited by two webs of the frame and comprises a pin on the locking member.

Verschlüsse dieser Art für Sicherheitsgurte sind wegen ihrer robusten und einfachen Mechanik, ihrer hohen Zuverlässigkeit und der geringen Betätigungskräfte auch unter Belastung schon seit vielen Jahren in Gebrauch.Buckles of this type for seat belts have been in use for many years because of their robust and simple mechanics, their high reliability and the low actuation forces, even under load.

Bei der weitgehend automatisierten Montage dieser Verschlüsse kann es zu einem Montagefehler kommen, der darin besteht, daß die zwischen den Schwenkriegel und das Sperrglied eingesetzte Druckfeder so eingebaut ist, daß sie sich zwar an dem Sperrglied abstützt, jedoch nicht in der vorgesehenen Weise in ihrer Aufnahme zu liegen kommt. Dieser Montagefehler äußert sich nur in einer von dem vorgeschriebenen Wert geringfügig abweichenden Federkraft und kann daher unbemerkt bleiben.In the largely automated assembly of these closures, an assembly error can occur, which consists in the fact that the compression spring inserted between the pivot bolt and the locking member is installed in such a way that it is supported on the locking member, but not in the intended manner in its receptacle comes to rest. This assembly error manifests itself only in a spring force that deviates slightly from the prescribed value and can therefore remain unnoticed.

In diesem Zusammenhang ist es Aufgabe der Erfindung, einen Verschluß der eingangs genannten Art für Sicherheitsgurte dahingehend weiterzubilden, daß eine Fehlmontage der Feder ausgeschlossen ist.In this context, it is an object of the invention to further develop a fastener of the type mentioned at the beginning for seat belts in such a way that incorrect assembly of the spring is excluded.

Diese Aufgabe wird bei einem Verschluß der eingangs angegebenen Art dadurch gelöst, daß das sperrgliedseitige Ende der Druckfeder und die Federaufnahme mit Formgestaltungen versehen sind, durch die das sperrgliedseitige Federende auf dem Zapfen zwangszentriert ist.This object is achieved in a closure of the type specified in the introduction in that the locking member-side end of the compression spring and the spring receptacle are provided with shapes by means of which the locking member-side spring end is positively centered on the pin.

In der nachfolgenden Beschreibung und den beigefügten Zeichnungen ist die bevorzugte Ausführungsform der Erfindung dargestellt. In den Zeichnungen zeigen:

  • Fig. 1 einen Querschnitt durch einen erfindungsgemäßen Verschluß;
  • Fig. 2 einen teilweise geöffneten, erfindungsgemäßen Verschluß;
  • Fig. 3 einen Teil eines Verschlusses nach dem Stand der Technik mit fehlerhaft montierter Feder;
  • Fig. 4 einen Querschnitt durch eine Feder gemäß einer Ausführungsform der Erfindung.
The preferred embodiment of the invention is illustrated in the following description and the accompanying drawings. The drawings show:
  • 1 shows a cross section through a closure according to the invention.
  • 2 shows a partially opened closure according to the invention;
  • 3 shows a part of a closure according to the prior art with an incorrectly fitted spring;
  • Fig. 4 shows a cross section through a spring according to an embodiment of the invention.

In den Figuren 1 und 2 ist ein Verschluß für Sicherheitsgurte gezeigt, bei welchem in einem lasttragenden Rahmen 14 ein Schwenkriegel 16 gelagert ist, der in seiner Sperrstellung an einer Rastkante einer Steckzunge 10 angreift. Im Rahmen 14 ist ein Sperrglied 20 quer zur Schwenkrichtung des Schwenkriegels 16 zwischen einer Öffnungsstellung, in der es den Schwenkriegel freigibt, und einer Sperrstellung verschiebbar gelagert, in der es den Schwenkriegel in seiner Eingriffsstellung blockiert. Im Rahmen 14 ist auch eine Lösetaste 24 gelagert, durch deren Betätigung das Sperrglied 20 in seine Öffnungsstellung verschiebbar ist. Eine zwischen dem Schwenkriegel 16 und dem Sperrglied 20 angeordnete schraubenförmige Druckfeder 30 stützt sich mit ihrem einen Ende an dem Schwenkriegel 16 und mit ihrem anderen Ende 40 an dem Sperrglied 20 ab und ist in einer Federaufnahme gehalten, die von zwei Stegen 50 des Rahmens 14 begrenzt ist und einen Zapfen 35 am Sperrglied 20 umfaßt. Die Druckfeder 30 beaufschlagt sowohl den Schwenkriegel 16 in seine Öffnungsstellung als auch das Sperrglied 20 in seine Sperrstellung.In Figures 1 and 2, a fastener for seat belts is shown, in which a pivot bolt 16 is mounted in a load-bearing frame 14, which engages in its locked position on a locking edge of a tongue 10. In the frame 14, a locking member 20 is slidably mounted transversely to the pivoting direction of the pivot bolt 16 between an open position in which it releases the pivot bolt and a blocking position in which it blocks the pivot bolt in its engaged position. A release button 24 is also mounted in the frame 14, the actuation of which allows the locking member 20 to be displaced into its open position. A helical compression spring 30 arranged between the swivel bar 16 and the locking member 20 is supported at one end on the swivel bar 16 and at the other end 40 on the locking member 20 and is held in a spring receptacle which is delimited by two webs 50 of the frame 14 is and comprises a pin 35 on the locking member 20. The compression spring 30 acts on both the pivot bolt 16 in its open position and the locking member 20 in its locking position.

Wie am besten in Fig. 3 gesehen werden kann, die einen gattungsgemäßen Verschluß nach dem Stand der Technik darstellt, weist die Aufnahme für die Druckfeder 30 an dem Sperrglied 20 einen Zapfen 35 zur Zentrierung der Druckfeder 30 auf. Bei dieser Gestaltung der Bauteile des Verschlusses kann, wie in der Figur dargestellt, die Druckfeder 30 fehlerhaft montiert werden, so daß sie nicht von dem Zapfen 35 zentriert wird. Sie stützt sich dann auf einem neben dem Zapfen 35 liegenden Abschnitt der der Druckfeder zugewandten Seite des Sperrglieds 20 ab. Eine Fehlmontage dieser Art ist bei der Herstellung dieser Verschlüsse offensichtlich unerwünscht, da durch sie die tatsächliche Federkraft von dem vorgeschriebenen Wert abweichen kann.As can best be seen in FIG. 3, which represents a generic closure according to the prior art, the receptacle for the compression spring 30 on the locking member 20 has a pin 35 for centering the compression spring 30. With this design of the components of the closure, as shown in the figure, the compression spring 30 can be mounted incorrectly so that it is not centered by the pin 35. It is then supported on a section lying next to the pin 35 on that side of the locking member 20 which faces the compression spring. Incorrect assembly of this type is obviously undesirable in the manufacture of these closures, since the actual spring force can deviate from the prescribed value.

Um nun eine Fehlmontage der oben beschriebenen Art zu verhindern, sind erfindungsgemäß das sperrgliedseitige Ende der Druckfeder und die Federaufnahme mit Formgestaltungen versehen, durch die das sperrgliedseitige Federende auf dem Zapfen zwangszentriert ist.In order to prevent incorrect assembly of the type described above, according to the invention the end of the compression spring on the locking member side and the spring receptacle are provided with shapes by means of which the locking member end of the spring is positively centered on the pin.

In der bevorzugten und in den Figuren 1, 2 und 4 dargestellten Ausführungsform der Erfindung ist das sperrgliedseitige Ende 40 der Druckfeder 30 flanschartig mit einem größeren Durchmesser als ihre Arbeitswindungen ausgebildet. Dieser größere Durchmesser des Federendes 40 wird durch wenigstens eine weitere, hinsichtlich der Arbeitswindungen der Druckfeder 30 im Durchmesser vergrößerte Windung nach Art einer Führungswindung gebildet, die, wie am besten in Fig. 4 zu sehen ist, im Anschluß an die die Arbeitswindungen abschließende, beigedrückte Windung in der Ebene dieser Windung gebildet ist. Diese im Durchmesser vergrößerte, spiralförmige Windung ist mit nahezu aneinanderliegenden Windungsgängen bis zu einem solchen Außendurchmesser des Federendes 40 ausgeführt, daß im Zusammenwirken mit den Stegen 50 des Rahmens 14 eine Zwangszentrierung des Federendes 40 in der Federaufnahme eintritt. Durch diese Zwangszentrierung wird die in Fig. 3 gezeigte, fehlerhafte Montage des Federendes 40 in der Federaufnahme verhindert.In the preferred embodiment of the invention shown in FIGS. 1, 2 and 4, the end 40 of the compression spring 30 on the locking member side is flange-shaped with a larger diameter than its working windings. This larger diameter of the spring end 40 is formed by at least one further turn, enlarged in diameter with regard to the working turns of the compression spring 30, in the manner of a guide turn, which, as can best be seen in FIG. 4, is squeezed after the work turns which terminate Winding is formed in the plane of this winding. This enlarged spiral-shaped turn is designed with almost adjacent turns up to such an outer diameter of the spring end 40 that in cooperation with the webs 50 of the frame 14, a forced centering of the spring end 40 occurs in the spring receptacle. This forced centering prevents the incorrect assembly of the spring end 40 in the spring receptacle shown in FIG. 3.
