Description
Die Erfindung betrifft ein Drehfallenschloß nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a rotary latch lock according to the preamble of Patent claim 1.
Derartige
Drehfallenschlösser,
wie sie z.B. aus
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Drehfallenschloß der als bekannt vorausgesetzten Art so auszubilden, daß ein Abrutschen von Sperrklinke und Drehfalle erschwert oder unmöglich gemacht wird.outgoing From this prior art, the invention is based on the object a rotary latch lock the as a known presumed kind in such a way that slipping is made difficult or impossible by pawl and rotary latch.
Die Lösung dieser Aufgabe erfolgt alternativ mit den Merkmalen des Patentanspruchs 1 oder des Patentanspruchs 2.The solution This object is alternatively with the features of the claim 1 or claim 2.
Die Erfindung lehrt ein bei hoher Belastung im Crashfall erfolgendes Blockieren von Sperrklinke und Drehfalle gegen wechselseitiges seitliches Ausweichen. Hierzu genügt es, einen an einem der beiden zusammenwirkenden Elemente seitlich angeordneten Verstärkungsbereich, der im Verriegelungszustand einen Teilbereich des komplementären Elements seitlich übergreift, durch eine Platte auszubilden. Diese Platte übergreift vorteilhaft eine Stirnkante der Sperrklinke bzw. der Drehfalle und ist auf der dem Plattenbereich gegenüberliegenden Seite in Gegenrichtung abgebogen.The Invention teaches at high load in the event of a crash Blocking pawl and rotary latch against reciprocal lateral Dodge. This is enough it, one on one of the two interacting elements laterally arranged reinforcement area, in the locked state, a portion of the complementary element overlaps laterally, to form through a plate. This plate advantageously overlaps one Front edge of the pawl or the catch and is on the Plate area opposite Side bent in the opposite direction.
Die erfindungsgemäße Lösung erzielt mit geringem Aufwand eine wesentliche Verbesserung der Crashsicherheit von üblichen Drehfallenschlössern.The achieved inventive solution With little effort, a significant improvement in crash safety from usual Rotary latch locks.
Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung im einzelnen beschrieben. Es zeigen:below becomes a preferred embodiment the invention described in detail with reference to the drawing. It demonstrate:

neben dem Klinkenmaul
In
der dargestellten Ausführungsform
ist der das seitliche Ausweichen verhindernde Verstärkungsbereich
