Abstract

The friction to be overcome during fastening an unfastening the safety belt fastener is reduced by adding rollers (6) to the spring loaded blocking piece (10) so that when the tongue (2) is inserted the front roller rolls over the inclined edge (9) of the tongue, thus reducing the force required to fasten the belt. When the belt is being unfastened, the initial pull is assisted by a spring (11) which pushes the tongue out. The tongue is a T-section head which has tapered corners to assist passage into the fastener and overt he rollers.

Description

SCHLOSS, INSBESONDERE FÜR SICHERHEITSGURTE Die Erfindung betrifft ein Schloss, insbesondere für Sicherheitsgurte, bei dem zur Reduzierung der Öffnungskr@fte dns Sperrglied aus einem oder mehreren rollenförmigen @örpern besteht.LOCK, IN PARTICULAR FOR SEAT BELTS The invention relates to a lock, especially for seat belts, in which to reduce the opening force The locking member consists of one or more roller-shaped bodies.

Die Sperrglieder in den bekannteu Schlössern sind so geformt, das diese im Zusammenwirken mit der Schlosszunge seinerseits tind mit dem Widerlager iia Schloss andererseits beim Offn(n die doppelte Gleitreibung erzeugen, was zu hohen Öffnungskräften führt.The locking links in the well-known locks are shaped so that this, in cooperation with the lock tongue, is in turn with the abutment iia lock on the other hand when opening (n generate double the sliding friction, which leads to high opening forces.

Das Wesen der Erfindung ist, durch Verwendung von rollenförmigen Sperrgliedern die bekannte doppelte Gleitreibung auf eine Rollreibung zu reduzieren. In der Zeich-Iiung ist die Erfindung beispielsweise dargestellt. Die Zeichnung zeigt das Schloss im Querschnitt in der Verschlußstellung.The essence of the invention is through the use of roller-shaped locking members to reduce the known double sliding friction to rolling friction. In the drawing the invention is illustrated by way of example. The drawing shows the lock in Cross-section in the closed position.

Das Schloss dient zur lösbaren Verbindung der am Gurtband 1 angeordneten Schloßzunge 2 mit den im Schloßgehäuse 3 befindlichen Sperrelementen, die in bekannter Weise über Beschlagteile 4 mit dem Fahrzeug fest verbunden sind. Im Schloßgehäuse 3 ist die mit dem Beschlagteil 4 zusammen-Sefügte Grundplatte 5 angeordnet. Zweckmässigerweise besteht die Grundplatte aus 2 Platten, damit die Schloßzunge zwischen den Platten geführt werden kann. In der Grundplatte sind die rollenförmigen Sperrglieder 6 angeordnet, welche mittels Drucktaste 7 über die Auslösefläche i4 aus der dargestellten Verschlubstellung gegen die Kraft der Drucktastenfeder 8 herausbewegt werden können. Wirde das Schloss belastet, so iibertrgt sich die Kraft über die Sperrkante 9 der Schloßzunge auf die rollenfömigen Sperrglieder 6, die sich ihrerseits an der Sperrfläche 10 der Grundplatte 5 abstützen.The lock is used for the detachable connection of those arranged on the belt strap 1 Lock tongue 2 with the locking elements located in the lock housing 3, which in known Way are firmly connected to the vehicle via fittings 4. In the lock case 3, the base plate 5, which is joined together with the fitting part 4, is arranged. Appropriately the base plate consists of 2 plates, so that the lock tongue between the plates can be performed. The roller-shaped locking members 6 are arranged in the base plate, which by means of push button 7 via the trigger surface i4 from the illustrated Locking position can be moved out against the force of the push button spring 8. Will the castle loaded, the force is transmitted via the locking edge 9 of the lock tongue the rollenfömigen locking members 6, which in turn on the locking surface 10 of the Support base plate 5.

Durch die symmetrische Ausbildung der Schloßzunge kann diese auch um 180° gedreht in das Schloßgehäuse eingeführt werden.Due to the symmetrical design of the lock tongue, this can also rotated by 180 ° are inserted into the lock housing.

Sind die Sperrglieder 6 mit der Schloßzunge ausser Eingriff, so wirft die Schloßzungenfeder 11 die SchloLzunge aus. Die Drucktastenfeder 8 drückt die Drucktaste in die Ausgangslage zurück, oei die an der Drucktaste vorgesehene Fläche 12 die Sperrglieder in die Sperrlage zurückbewegt. Die Einlaufschräge 23 erlaubt ein leichtes Einführen der Schloßzunge.If the locking members 6 are disengaged from the lock tongue, it throws the lock tongue spring 11, the lock tongue. The push button spring 8 pushes the Push button back to the starting position, oei the area provided on the push button 12 moved the locking members back into the locking position. The run-in slope 23 allows easy insertion of the lock tongue.

Selbstverständlich können die Schlollteile auch anders ausgeführt werden. So ist es nicht erforderlich, daß die Sperrgiieder durch die Drucktaste direkt betätigt werden.Of course, the Schloll parts can also be designed differently will. So it is not necessary that the locking member by the push button can be operated directly.

Die Betätigung kann auch über an der Drucktaste vorgesehene Schrägflächen oder über Hebelübersetzungen erfolgen.It can also be actuated via inclined surfaces provided on the pushbutton or via leverage.
