Abstract

The two ends of the seat belt webbing (2a) are locked together by hook arrangement (3, 3a). Web end (2a) is fitted to casing (1). Hook (3a) is fitted on the end of a rocker lever (13) pivoting around a fulcrum (5) seated in a slot (6) of the casing (1). The shorter arm of the rocker lever is kept in engagement with the hook (3) by a leaf spring (4) and the longer arm is fitted with a spiral spring (7) which tries to pull the arm towards the webbing end (2a). When the traction on the webbing ends is so large that the force of the spring is overcome, the casing (1) moves relatively away from the engaged hooks (3, 3a) sliding in the slot (6). By this movement locking arm (9) becomes ineffective. At the same time the spiral spring (10) is wound-up and screw gear fitted at its end turns the cam (12) which presses down longer arm of rocker hereby pushing hook (3a) out of engagement.

Description

Vorrichtung Zinn automatischen Öffnen von Sicherheitsgurten Die Erfindung betrifft eine Vorrichtung, welche bei Sicherheitsgurten zwischengeschaltet oder auch im Schloß desselben mit eingebaut ist und dienach extremer Belastung des Gurtes bei einem Unfall mit Zeitverzögerung den Gurt öffnet.Device tin automatic opening of seat belts The invention relates to a device which is interposed or in seat belts is also built into the lock and after extreme stress on the belt opens the seat belt with a time delay in the event of an accident.

Die bekannten Sicherheitsgurte sind so konstruiert, daß diese nur von Hand geöffnet werden können. Dies kann sich bei Unfällen, bei denen der Insasse des Bahrzeuges bewußtlos ist und schnelle Hilfe von außen notwendig ist, z.B. beim Ausbruch von Feuer, sehr nachteilig auswirken.The known seat belts are designed so that these only can be opened by hand. This can occur in accidents involving the occupant of the vehicle is unconscious and quick outside help is necessary, e.g. when Outbreak of fire, very detrimental.

Aufgabe der Erfindung ist, durch automatisches Öffnen des Gurtes nach Ablauf einer bestimmten Zeit nach einem Aufprall diese Nachteile der bekannten Sicherheitsgurte zu beseitigen.The object of the invention is to automatically open the belt after Lapse of a certain time after an impact these disadvantages of the known seat belts to eliminate.

Brtndungsgemäß wird dieses Ziel dadurch erreicht, daß durch die auftretenden Kräfte ab einer bestimmten Belastung des Gurtes eine Vorrichtung oder mehrere Vorrichtungen in Tätigkeit gesetzt wird oder werden, welche nach Ablauf einer bestimmten Zeit eine Verbindung oder Verbindungen des Gurtes entriegelt oder die Entriegelung veranlaßt bzw. veranlassen.According to the plan, this goal is achieved in that by the occurring Forces above a certain load on the belt one device or several devices is or will be put into action after a certain period of time unlocks a connection or connections of the belt or causes the unlocking or cause.

Eine vorteilhafte Konstruktion ist derart, daß durch die Belastung des Gurt es bei einem Unfall ein Pederwerk in Tätigkeit gesetzt wird, welches wiederum einen Exzenter in Drehbewegung versetzt und dieser das Schloß des Gurtes öffnet.An advantageous construction is such that by the load of the belt, a pedal mechanism is activated in the event of an accident, which in turn an eccentric set in rotation and this opens the buckle of the belt.

Es sind auch Konstruktionen möglich, bei denen die Entriegelung elektrisch bzw. elektromagnetisch oder aber durch einen kleinen Sprengsatz erfolgt.Constructions are also possible in which the unlocking is electrical or electromagnetically or by a small explosive device.

In den Zeichnungen ist ein Ausführungsbeispiel dargestellt: Es zeigt Fig. 1 Ein Sicherheitsgurtschloß in Seitenansicht im Schnitt und Fig. 2 davon die Draufsicht im Schnitt, In Fig. 1 und 2 ist das Schloß 1 eines Sicherheitsgurtes schematisch dargestellt, wobei die Vorrichtung zum automatischen Öffnen im Schloß mit eingebaut ist. Die an den beiden Enden des Gurtes 2 und 2a angebrachten Klauen 3 und 3a bilden den Verschluß, der natürlich auch von Hand dadurch zu öffnen ist, daß die Klaue 3a, welche durch die Plattfeder 4 nach unten gedrückt wird, angehoben wird, Der Drehpunkt 5 der Klaue 3a ist in Langlöchern 6 gelagert und wird durch die Zugfedern 7 an das hintere Ende der Langlöcher gepreßt. Diese Zugfedern 7 haben eine so große Zugkraft, daß diese nur bei hoher Belastung überwunden wird un-d die Klaue 3a beim Auftreten einer solchen Belastung etwas in Richtung des Pfeiles 8 bewegt wird, wodurch wiederum der Arretierungshebel 9 außer Wirkung gebracht wird und somit das Federwerk 10 in Xätigkeit gesetzt wird und in üblicher, nicht dargestellter Weise übersetzt, den Exzenter 11 in Richtung des Pfeiles 12 dreht. Dadurch, daß der Exzenter 11 auf den hinteren Hebelarm 13 der Klaue 3a drückt, wird diese angehoben und somit der Verschluß geöffnet.In the drawings, an embodiment is shown: It shows Fig. 1 A seat belt buckle in side view in section and Fig. 2 thereof Top view in section, In Fig. 1 and 2, the lock 1 is a seat belt shown schematically, the device for automatic opening in the lock is built in. The claws attached to the two ends of the belt 2 and 2a 3 and 3a form the lock, which can of course also be opened by hand that the claw 3a, which is pressed down by the flat spring 4, is raised is, the fulcrum 5 of the claw 3a is mounted in slots 6 and is through the tension springs 7 pressed against the rear end of the elongated holes. These tension springs 7 have such a large tensile force that it can only be overcome under high loads and the Claw 3a when such a load occurs somewhat in the direction of arrow 8 is moved, which in turn the locking lever 9 is disabled and thus the spring mechanism 10 is set in action and in the usual, not shown Way translated, the eccentric 11 rotates in the direction of arrow 12. As a result of that the eccentric 11 presses on the rear lever arm 13 of the claw 3a, this is raised and thus the shutter opened.
