Abstract

Simple shockproofing is to be provided in a safety belt buckle receiving and retaining a tongue in a casing with an insertion path for the tongue containing a spring-loaded ejector, and having a locking element guided in the buckle cooperating with the tongue recess when locked to lock the tongue in the insertion path, and a spring-loaded push-button guided in the lock housing to unlock the buckle. To this end, the push-button (20) is formed in two parts with a button (26) movable in relation to the push-button body (25) against the action of a sensor spring (28) and the push-button body (25) can be pushed into the buckle casing without actuating the locking element (18, 22) and the relative movement between the push-button (26) and the push-button body (25) can be converted into the actuation of the locking element (18, 22).

Description

Die Erfindung betrifft einen Sicherheitsgurtverschluß zur Aufnahme und Verriegelung einer Einsteckzunge mit einem Gehäuse und einem darin, einen unter Federwirkung stehenden Auswerfer enthaltenden Einschubweg für die Einsteckzunge, mit einer mit der Zungenausnehmung im Verriegelungsfall zusammenwirkenden Verriegelung, welche die Einsteckzunge in dem Einschubweg verriegelt, und mit einer im Verschlußgehäuse geführten, federbelasteten und zweiteilig mit einem Schiebetastenkörper und einem darin einschiebbaren Tastenfeld ausgebildeten Schiebetaste zur Aufhebung der Verriegelung, wobei eine zwischen Schiebetastenkörper und Tastenfeld angeordnete Feder als Sensorfeder bei auftretenden Beschleunigungen das Tastenfeld im wesentlichen in der ausgeschobenen Stellung hält und bei manueller Betätigung der Schiebetaste eine Relativbewegung zwischen Tastenfeld und Schiebetastenkörper in die Betätigung der Verriegelung umsetzbar ist.The invention relates to a seat belt buckle for receiving and locking an insertion tongue with a housing and an insertion path for the insertion tongue containing an ejector under spring action, with a locking device which interacts with the tongue recess in the event of locking and which locks the insertion tongue in the insertion path, and with a guided in the breech housing, spring-loaded and designed in two parts with a sliding key body and a push-in push-button designed sliding key for releasing the locking, whereby a spring arranged between the push-button body and push-button field as sensor spring holds the push-button panel essentially in the extended position when accelerations occur and when the push-button is operated manually a relative movement between the keypad and sliding key body can be implemented in the actuation of the lock.

Ein gattungsgemäßer Sicherheitsgurtverschluß ist in der DE-A-38 11 429 beschrieben; danach ist vorgesehen, daß der Schiebetastenkörper gegen das Verschlußgehäuse verriegelt ist, so daß bei einwirkenden Beschleunigungskräften der Verschlußkörper in seiner Ruhestellung verbleibt, wobei das beschleunigungsbedingte Einschieben des Tastenfeldes in den Schiebetastenkörper diese Verriegelung des Schiebetastenkörpers im Verschlußgehäuse nicht aufhebt. Erst die manuelle Betätigung des Tastenfeldes läßt dieses die Verriegelung des Schiebetastenkörpers im Verschlußgehäuse aufheben, so daß mit fortschreitendem Öffnungshub der Schiebetastenkörper die Entriegelung des Verschlußmechanismus herbeiführt.A generic seat belt buckle is described in DE-A-38 11 429; then it is provided that the sliding button body is locked against the closure housing, so that the accelerating forces acting on the closure body in its rest position remains, the acceleration-related insertion of the keypad into the sliding key body does not cancel this locking of the sliding key body in the lock housing. Only the manual actuation of the keypad can release the locking of the sliding key body in the lock housing, so that the sliding key body brings about the unlocking of the locking mechanism as the opening stroke progresses.

Mit dem bekannten Verschluß ist der Nachteil verbunden, daß die aufzuhebende Verriegelung des Schiebetastenkörpers im Verschlußgehäuse der normalen, von der Benutzerperson ausgehenden Öffnungsbewegung des Verschlusses einen Widerstand entgegensetzt, der den Bedienungskomfort des Verschlusses mindert. Weiterhin müssen die Verriegelungskräfte einerseits und die von dem zugelassenen Einschieben des Tastenfeldes in den Schiebetastenkörper ausgehenden Öffnungskräfte andererseits exakt aufeinander abgestimmt sein, um mit der gebotenen Sicherheit eine Entriegelung des Schiebetastenkörpers im Verschlußgehäuse zu vermeiden. Schließlich weist der bekannte Verschluß einen komplizierten Aufbau auf, weil die Mittel zur Verriegelung des Schiebetastenkörpers einerseits und zur Aufhebung der Verriegelung andererseits entsprechend vorgehalten werden müssen.The known lock has the disadvantage that the unlocking of the sliding button body in the lock housing opposes the normal opening movement of the lock which starts from the user, which reduces the ease of use of the lock. Furthermore, the locking forces on the one hand and the opening forces emanating from the approved insertion of the keypad into the sliding key body on the other hand must be exactly coordinated with one another in order to avoid unlocking the sliding key body in the lock housing with the required security. Finally, the known closure has a complicated structure because the means for locking the sliding button body on the one hand and for releasing the locking on the other hand must be appropriately provided.

Der Erfindung liegt daher die Aufgabe zugrunde, einen gattungsgemäßen Sicherheitsgurtverschluß derart zu verbessern, daß bei hohem Bedienungskomfort der Verschluß gegen in der Wirkungsrichtung der Schiebetaste wirkende Beschleunigungskräfte schockgesichert ist, wobei der Aufbau des Verschlusses einfach sein soll.The invention is therefore based on the object of improving a generic seat belt buckle in such a way that, with a high degree of operating comfort, the buckle is shock-protected against acceleration forces acting in the direction of action of the sliding button, the structure of the buckle should be simple.

Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.This object is achieved, including advantageous refinements and developments, from the content of the patent claims, which follow this description.

Die Erfindung sieht hierzu in ihrem Grundgedanken vor, daß der Schiebetastenkörper mit Tastenfeld im Beschleunigungsfall bei Nicht-Betätigung des Tastenfeldes ohne Aufhebung der Verriegelung des Verschlusses in Öffnungsrichtung der Schiebetaste in das Verschlußgehäuse einschiebbar ist.The basic idea of the invention provides that the sliding key body with keypad can be pushed into the closure housing in the acceleration direction when the keypad is not actuated without releasing the lock of the lock in the opening direction of the sliding key.

Mit der erfindungsgemäßen Ausgestaltung ist der Vorteil verbunden, daß eine Betätigung der Verriegelung des Verschlusses nur dann erfolgt, wenn das Tastenfeld in den Schiebetastenkörper eingedrückt und dann gemeinsam mit dem Schiebetastenkörper im Sinne einer Entriegelungsbewegung für die Verriegelung des Verschlusses bewegt wird. Erst der Einschub des Tastenfeldes in den Schiebetastenkörper führt zur Ausbildung einer äußeren Gestalt des Schiebetastenkörpers durch entsprechend vorspringende Teile, mit welcher der Schiebetastenkörper auf die Verriegelung einwirkt. Solange das Tastenfeld in den Schiebetastenkörper nicht eingeschoben ist, ist der Schiebetastenkörper in dem Verschlußgehäuse zum Beispiel durch Beschleunigungskräfte ohne Betätigung der Verriegelung frei verschiebbar. Bei dieser Ausgestaltung ist durch eine entsprechende Auslegung der Sensorfeder zwischen Schiebetastenkörper und Tastenfeld lediglich dafür Sorge zu tragen, daß bei schockartiger Beanspruchung sich das Tastenfeld für eine Betätigung der Verriegelung nicht beziehungsweise nicht zu weit in den Schiebetastenkörper einschiebt. Der in der Praxis übliche Leerweg zur Abdeckung von Fertigungstoleranzen ist in der Zeichnung dargestellt. Bei Auftreten eines Schocks kann sich dann der Schiebetastenkörper einschließlich des Tastenfeldes ohne Beeinflussung der Verriegelung im Verschlußgehäuse bewegen, so daß in vorteilhafter Weise die Sensorfeder nur die Masse des Tastenfeldes abfangen muß und nicht die gesamte Schiebetaste mit Schiebetastenkörper und Tastenfeld gegen eine Schockbeanspruchung zu sichern ist.The embodiment of the invention has the advantage that the locking of the lock is actuated only when the keypad is pressed into the sliding button body and then moved together with the sliding button body in the sense of an unlocking movement for locking the lock. Only the insertion of the keypad into the sliding key body leads to the formation of an outer shape of the sliding key body by correspondingly projecting parts with which the sliding key body acts on the locking. As long as the keypad is not inserted into the sliding key body, the sliding key body can be moved freely in the lock housing, for example by acceleration forces, without actuating the lock. In this embodiment, it is only necessary to ensure that the sensor spring between the sliding key body and the keypad is designed in such a way that the keypad is suitable for actuating the lock in the event of a shock-like load does not or does not insert too far into the sliding key body. The usual free travel to cover manufacturing tolerances is shown in the drawing. In the event of a shock, the sliding key body, including the keypad, can then move without influencing the locking in the lock housing, so that the sensor spring advantageously has to intercept only the mass of the keypad and the entire sliding key with the sliding key body and keypad cannot be secured against a shock load.

Nach einem Ausführungsbeispiel ist vorgesehen, daß in dem Schiebetastenkörper ein von dem Tastenfeld bei dessen Einschub in den Schiebetastenkörper betätigter Kipphebel angeordnet ist, der aus der Kontur des Schiebetastenkörpers herausschwenkbar ist und dabei einen Anschlag zur Betätigung der Verriegelung ausbildet. Hierbei wirkt der Kipphebel als ein Übertragungselement, mit welchem die Einschubbewegung des Tastenfeldes in den Schiebetastenkörper bei der normalen Betätigung des Verschlusses zum Herausschwenken eines Anschlages für die Betätigung der Verriegelung aus dem Schiebetastenkörper sorgt. Da gleichzeitig vorgesehen ist, daß der Kipphebel über eine sich am Schiebetastenkörper abstützende Rückstellfeder in seiner in die Kontur des Schiebetastenkörpers eingeschwenkten Stellung gehalten ist, ist bei nicht eingeschobenem Tastenfeld der Schiebetastenkörper im Sinne der Erfindung in dem Verschlußgehäuse frei verschieblich, ohne daß damit eine Betätigung der Verriegelung verbunden ist. Erst das Einschieben des Tastenfeldes in den Schiebetastenkörper mit der damit verbundenen Relativbewegung führt zur Betätigung des Kipphebels und dem Herausschwenken eines entsprechenden Anschlages zur Betätigung der Verriegelung. Auf den Kipphebel wirken dabei ebenfalls Beschleunigungskräfte, und daher sollte der Hebel entweder im Masseschwerpunkt gelagert sein beziehungsweise durch entsprechende Masseverteilung ein die Feder zur Abstützung des Kipphebels unterstützendes Verhalten aufweisen.According to one embodiment, it is provided that a rocker arm actuated by the keypad when it is inserted into the sliding key body is arranged in the sliding key body and can be pivoted out of the contour of the sliding key body and thereby forms a stop for actuating the lock. Here, the rocker arm acts as a transmission element, with which the pushing-in movement of the keypad into the sliding key body, during the normal actuation of the closure for pivoting out a stop, ensures the actuation of the lock from the sliding key body. Since at the same time it is provided that the rocker arm is held in its position pivoted into the contour of the sliding key body via a return spring which is supported on the sliding key body, the sliding key body can be moved freely in the lock housing within the meaning of the invention when the keypad is not inserted, without actuating the Interlock is connected. It is only when the keypad is pushed into the sliding key body with the relative movement associated with it that the rocker arm is actuated and a corresponding stop is pivoted out to actuate the lock. Acceleration forces also act on the rocker arm, and therefore the lever should either be at the center of gravity be stored or have a behavior supporting the spring for supporting the rocker arm by appropriate mass distribution.

Nach einem anderen Ausführungsbeispiel ist eine das Tastenfeld tragende Betätigungsstange in dem Schiebetastenkörper derart verschiebbar, daß bei Relativbewegung des Tastenfeldes gegenüber dem Schiebetastenkörper das Ende der Betätigungsstange aus der Kontur des Schiebetastenkörpers heraustritt und somit die Verriegelung des Verschlusses beaufschlagt. Bei diesem Ausführungsbeispiel ist auf die Anordnung eines gesonderten Übertragungselementes verzichtet, vielmehr wird die auch zur Führung des Tastenfeldes dienende Betätigungsstange sogleich als Übertragungselement für die Betätigung der Verriegelung benutzt. Vorzugsweise ist diese Betätigungsstange dabei in einem den Schiebetastenkörper schräg durchsetzenden Kanal geführt, woraus sich aber auch ergibt, daß bei Betätigung des Tastenfeldes es zu einem Versatz des Tastenfeldes gegenüber dem Schiebetastenkörper kommt.According to another exemplary embodiment, an actuating rod carrying the keypad is displaceable in the sliding key body such that when the keypad moves relative to the sliding key body, the end of the actuating rod emerges from the contour of the sliding key body and thus acts on the locking of the closure. In this embodiment, the arrangement of a separate transmission element is dispensed with; rather, the actuating rod, which is also used to guide the keypad, is immediately used as a transmission element for actuating the lock. Preferably, this actuating rod is guided in a channel which penetrates the sliding key body at an angle, but this also means that when the key field is actuated, the key field is offset relative to the sliding key body.

Soll dieser Nachteil vermieden sein, so kann nach der Erfindung auch vorgesehen sein, die Betätigungsstange aus mehreren gelenkig aneinander angreifenden Abschnitten auszubilden, so daß ein geradlinig verlaufender Kanal mit einer geradlinigen Bewegung des Tastenfeldes angeordnet sein kann, der erst in seinem Endbereich derart umgelenkt ist, daß das Ende der Betätigungsstange aus der Kontur des Schiebetastenkörpers heraustritt.If this disadvantage is to be avoided, it can also be provided according to the invention that the actuating rod is formed from a plurality of articulated sections, so that a rectilinear channel with a rectilinear movement of the keypad can be arranged, which is only deflected in its end region in this way, that the end of the operating rod emerges from the contour of the sliding key body.

Bei den Ausführungsbeispielen mit einer in einem Kanal geführten Betätigungsstange ist es zweckmäßig, an der Betätigungsstange einen in eine den Verschiebeweg festlegenden Ausnehmung im Schiebetastenkörper eingreifenden Vorsprung vorzusehen.In the exemplary embodiments with an actuating rod guided in a channel, it is expedient to provide on the actuating rod a projection which engages in a recess in the sliding key body which defines the displacement path.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, das Tastenfeld mit Betätigungsstange, die Sensorfeder und den Schiebetastenkörper aus einem einzigen, aus Kunststoff bestehenden Teil auszubilden, wobei die an das Tastenfeld und an den Schiebetastenkörper jeweils anschließende Sensorfeder jeweils über Filmscharniere mit den Bauteilen verbunden ist. Derartige Teile lassen sich insbesondere im Spritzgußverfahren leicht herstellen und in den Mechanismus des Verschlusses einfügen.A preferred embodiment of the invention provides that the keypad with actuating rod, the sensor spring and the sliding key body from a single, Form part made of plastic, wherein the sensor spring adjoining the keypad and the sliding key body is each connected to the components via film hinges. Parts of this type can be easily produced, in particular by injection molding, and inserted into the mechanism of the closure.

Die Erfindung ist nicht auf gattungsgemäße Verschlüsse beschränkt, bei denen die Schiebetastenbewegung unmittelbar auf einen Riegel des Verschlusses wirkt, sondern sie ist auch anwendbar auf Verschlußbauarten, bei denen ein unter Selbstöffnungstendenz im Verschlußgehäuse gelagerter Riegel von einem Sicherungselement in seiner verriegelten Stellung gesichert ist; eine derartige Bauform des Verschlusses ergibt sich beispielsweise aus der DE-A-27 19 325. Für solche Verschlüsse ist die Erfindung ebenfalls anwendbar, wobei der Schiebetastenkörper mit seinem aus seiner Kontur bei Betätigung des Tastenfeldes heraustretenden Anschlag dann auf das Sicherungselement wirkt, dieses bei der weiteren Bewegung der Schiebetaste in dessen Freigabestellung verschiebt, so daß sich der unter Selbstöffnungstendenz stehende Riegel in seine Freigabestellung für die Einsteckzunge bewegt.The invention is not limited to generic closures, in which the slide button movement acts directly on a bolt of the closure, but it is also applicable to closure types in which a latch stored in the closure housing under self-opening tendency is secured by a securing element in its locked position; Such a design of the closure results, for example, from DE-A-27 19 325. The invention can also be used for such closures, the sliding key body then acting on the securing element with its stop emerging from its contour when the keypad is actuated, this element in the further movement of the slide button in its release position, so that the self-opening latch moves into its release position for the tongue.

Das in den Figuren dargestellte Ausführungsbeispiel zeigt einen Sicherheitsgurtverschluß, bei welchem der Riegel einer Verschluß-Verriegelung über ein im Verschlußgehäuse geführtes Sicherungselement festgelegt ist, welches von der Schiebetaste bei deren Entriegelungsbewegung beaufschlagt wird. Da der Verriegelungsmechanismus nicht Gegenstand der vorliegenden Erfindung ist, kann der Verschluß auch ohne weiteres so ausgebildet sein, daß die Schiebetaste bei ihrer Entriegelungsbewegung unmittelbar mit dem Riegel zusammenwirkt.The embodiment shown in the figures shows a seat belt buckle, in which the bolt of a buckle lock is fixed via a locking element guided in the buckle housing, which is acted upon by the slide button during its unlocking movement. Since the locking mechanism is not the subject of the present invention, the lock can also be designed so that the slide button interacts directly with the bolt when it is unlocked.

Gemäß Figur 1 besteht ein Sicherheitsgurtverschluß 10 aus einer einteiligen Schloßplatte 11, welche im Bereich ihrer Befestigung an einem Verankerungsteil 12 zu zwei gleich langen Schenkeln 13, 14 umgebogen ist, zwischen denen eine Einsteckzunge 15 gegen die Wirkung eines Auswerfers 16 einführbar ist. Der Verschluß weist zwei Seitenwände 17 auf, die dem Verschluß eine U-förmige Gestaltung geben; in den Seitenwänden 17 ist in dem hinteren Bereich ein Riegel 18 senkrecht zur Einsteckebene für die Einsteckzunge 15 drehbar in einem Gelenk 19 gelagert. Der Riegel 18 ist durch ein gleichsinnig mit der Schiebetaste 20 in den Seitenwänden 17 des Verschlusses 10 verschiebbar angeordnetes Sicherungselement 22 gesichert, welches in Langlöchern 21 in den Seitenwänden 17 verschiebbar geführt ist. In seiner auf die Schiebetaste 20 zu angeordneten Sicherungsstellung liegt das Sicherungselement 22 auf einem Vorsprung des Riegels 18 auf und sichert diesen gegen eine Öffnung. Bei der Entriegelungsbewegung wirkt die Schiebetaste 20 mit der erfindungsgemäßen und noch zu beschreibenden Ausgestaltung auf das Sicherungselement 22 ein und verschiebt dieses in eine Freigabestellung für den Riegel 18. Somit bilden Riegel 18 und Sicherungselement 22 die Verriegelung des Verschlusses.According to Figure 1, a seat belt buckle 10 consists of a one-piece lock plate 11, which is bent in the area of its attachment to an anchoring part 12 to two legs 13, 14 of equal length, between which an insertion tongue 15 can be inserted against the action of an ejector 16. The closure has two side walls 17 which give the closure a U-shaped configuration; in the side walls 17, a bolt 18 is rotatably mounted in a joint 19 in the rear region perpendicular to the insertion plane for the insertion tongue 15. The bolt 18 is in the same direction with the sliding button 20 in the side walls 17 of the closure 10 secured locking element 22 secured, which is slidably guided in elongated holes 21 in the side walls 17. In its securing position to be arranged on the sliding button 20, the securing element 22 rests on a projection of the latch 18 and secures it against an opening. During the unlocking movement, the sliding button 20 with the configuration according to the invention and still to be described acts on the securing element 22 and moves it into a release position for the latch 18. Thus latch 18 and securing element 22 form the locking of the closure.

Die Schiebetaste 20 im einzelnen besteht aus einem Schiebetastenkörper 25 und einem Tastenfeld 26, welches mittels einer Betätigungsstange 27 in dem Schiebetastenkörper 25 geführt ist. Zwischen Schiebetastenkörper 25 und Tastenfeld 26 ist eine Sensorfeder 28 angeordnet, welche das Tastenfeld 26 in dessen ausgeschobene Ruhelage vorspannt. Die Sensorfeder 28 ist dabei so stark zu bemessen, daß sie bei in der Bewegungsrichtung der Schiebetaste auftretenden Beschleunigungen das Tastenfeld in der ausgeschobenen Stellung zu halten in der Lage ist. Der Schiebetastenkörper 25 ist in seiner Kontur so abgestimmt, daß er gegenüber dem Sicherungselement 22 frei verschiebbar ist.The sliding key 20 in detail consists of a sliding key body 25 and a keypad 26 which is guided in the sliding key body 25 by means of an actuating rod 27. A sensor spring 28 is arranged between the sliding key body 25 and the keypad 26, which prestresses the keypad 26 in its extended position. The sensor spring 28 is dimensioned so strong that it is able to hold the keypad in the extended position when accelerations occur in the direction of movement of the sliding key. The contour of the slide button body 25 is adjusted in such a way that it can be freely moved relative to the securing element 22.

In dem Schiebetastenkörper 25 ist ein Kipphebel 29 derart gelagert, daß dessen einer Schenkel 30 mit der Betätigungsstange 27 des Tastenfeldes 26 zusammenwirkt und daß sein anderer Schenkel 31 bei Verschwenkung des Kipphebels 29 aus der Kontur des Schiebetastenkörpers 25 heraustritt. Der Kipphebel 29 ist durch eine sich zwischen dem Schenkel 30 und dem Schiebetastenkörper 25 abstützende Rückstellfeder 32 in seine in die Kontur des Schiebetastenkörpers 25 eingeschwenkte Stellung belastet, in welcher auch das Tastenfeld 26 sich in seiner vorderen Stellung befindet.In the sliding key body 25, a rocker arm 29 is mounted such that one leg 30 cooperates with the actuating rod 27 of the keypad 26 and that its other leg 31 emerges from the contour of the sliding key body 25 when the rocker arm 29 is pivoted. The rocker arm 29 is in its contour by a restoring spring 32 which is supported between the leg 30 and the sliding button body 25 of the sliding key body 25 loaded position, in which the keypad 26 is in its forward position.

Die Figur 2a zeigt in schematischer Darstellung die Schiebetaste in ihrer Ausgangslage. In Figur 2b ist das Verhalten der Schiebetaste bei Auftreten einer schockartigen Beschleunigung dargestellt, die ohne die erfindungsgemäße Ausbildung zu einer Entriegelung des Verschlusses führen würde. Nachdem nämlich zunächst der Verschluß in Richtung des Pfeiles 37 gestrammt worden ist, kommt es am Ende des Strammvorganges zu einer starken Abbremsung des Verschlußkörpers, so daß die Schiebetaste 20 danach trachtet, ihre Bewegung in Strammrichtung 37 fortzusetzen und dabei eine Einschubbewegung in den Verschluß auszuführen. Da durch die Sensorfeder 28 ein Einschieben des Tastenfeldes 26 in den Schiebetastenkörper 25 in Richtung des Pfeiles 37 ausgeschlossen ist, kann ein Einschieben der Schiebetaste 20 in den Verschluß unter der Wirkung der aufgetretenen Beschleunigungskräfte in Kauf genommen werden, weil, wie aus Figur 2b ersichtlich, die Schiebetaste 20 gegenüber dem Sicherungselement 22 frei verschiebbar ist, so daß das Einschieben der Schiebetaste 20 in den Verschlußkörper 10 nicht zu einer Entriegelung des Verschlusses führt.Figure 2a shows a schematic representation of the slide button in its initial position. FIG. 2b shows the behavior of the slide button when a shock-like acceleration occurs, which would lead to the lock being unlocked without the inventive design. After the closure has first been tightened in the direction of arrow 37, there is a strong braking of the closure body at the end of the tightening process, so that the slide button 20 seeks to continue its movement in the tightening direction 37 and thereby to insert a movement into the closure. Since the sensor spring 28 prevents the keypad 26 from being pushed into the sliding button body 25 in the direction of the arrow 37, pushing the sliding button 20 into the lock under the effect of the acceleration forces that occur can be accepted because, as can be seen from FIG. 2b, the slide button 20 is freely displaceable relative to the securing element 22, so that the insertion of the slide button 20 into the closure body 10 does not lead to the lock being unlocked.

Aus Figur 2c ergibt sich dagegen der Bewegungsablauf, wenn die Schiebetaste 20 im Sinne einer gewollten Entriegelung des Verschlusses betätigt wird. Dabei erfolgt ein Druck auf das Tastenfeld 26, und unter Überwindung der Kraft der Feder 28 wird das Tastenfeld in den Schiebetastenkörper 25 eingeschoben, wobei die Betätigungsstange 27 den Kipphebel 29 verschwenkt, so daß der Schenkel 31 aus der Kontur des Schiebetastenkörpers 25 herausschwenkt und bei der weiteren Einschubbewegung des Schiebetastenkörpers 25 gegen die Wirkung der Schiebetastenfeder 23 in das Verschlußgehäuse das Sicherungselement 22 beaufschlagt und in dessen Freigabestellung verschiebt. Somit ist also bei gewollter Entriegelung ein Bewegungsablauf zur Entriegelung des Verschlusses sichergestellt.In contrast, FIG. 2c shows the sequence of movements when the slide button 20 is actuated in the sense of an intentional unlocking of the closure. In this case, pressure is exerted on the keypad 26 and, overcoming the force of the spring 28, the keypad is inserted into the sliding key body 25, the actuating rod 27 pivoting the rocker arm 29, so that the leg 31 pivots out of the contour of the sliding key body 25 and, during the further insertion movement of the sliding key body 25 against the action of the sliding key spring 23 in the closure housing, acts on the securing element 22 and moves it into its release position. Thus, a movement sequence for unlocking the lock is ensured when unlocking is desired.

Bei dem in den Figuren 3a, b und 4 gezeigten Ausführungsbeispiel ist die das Tastenfeld 26 tragende Betätigungsstange 27 in einem schräg den Schiebetastenkörper 25 durchsetzenden Kanal 33 derart längsverschiebbar gelagert, daß bei Eindrücken des Tastenfeldes 26 in den Schiebetastenkörper 25 das freie Ende der Betätigungsstange 27 aus der Kontur des Schiebetastenkörpers 25 heraustritt und so den Anschlag für die Betätigung des Sicherungselementes 22 bildet. Zur Sicherung der Betätigungsstange 27 in dem Schiebetastenkörper 25 und zur Festlegung des Verschiebeweges weist die Betätigungsstange 27 einen Vorsprung 34 auf, der in einer zugeordneten Ausnehmung 35 des Schiebetastenkörpers 25 geführt ist. Die zwischen dem Schiebetastenkörper 25 und dem Tastenfeld 26 angeordnete Sensorfeder 28 ist wie das Tastenfeld und der Schiebetastenkörper auch aus Kunststoff gefertigt und einstückig mit den beiden vorgenannten Teilen über Filmscharniere 39 verbunden, so daß Schiebetastenkörper 25, Tastenfeld 26 mit Betätigungsstange 27 und Sensorfeder 28 jeweils als ein Kunststoff-Spritzgußteil herstellbar sind. Bei dem Einschub des Tastenfeldes 26 in den Schiebetastenkörper 25 ergibt sich aufgrund der schrägen Anordnung des Kanals 33 ein seitlicher Versatz des Tastenfeldes gegenüber dem Schiebetastenkörper.In the exemplary embodiment shown in FIGS. 3a, b and 4, the actuating rod 27 carrying the keypad 26 is mounted so as to be longitudinally displaceable in a channel 33 passing obliquely through the sliding key body 25 such that when the keypad 26 is pressed into the sliding key body 25, the free end of the actuating rod 27 is out the contour of the sliding button body 25 emerges and thus forms the stop for the actuation of the securing element 22. To secure the actuating rod 27 in the sliding key body 25 and to determine the displacement path, the actuating rod 27 has a projection 34 which is guided in an associated recess 35 in the sliding key body 25. The arranged between the sliding key body 25 and the keypad 26 sensor spring 28 is like the keypad and the sliding key body also made of plastic and integrally connected to the two aforementioned parts via film hinges 39, so that the sliding key body 25, keypad 26 with actuating rod 27 and sensor spring 28 each as a plastic injection molded part can be produced. When the keypad 26 is inserted into the sliding key body 25, the oblique arrangement of the channel 33 results in a lateral offset of the keypad relative to the sliding key body.

Soll dieser Versatz vermieden werden, so kann gemäß dem in den Figuren 5a, b vorgesehenen Ausführungsbeispiel die Betätigungsstange 27 auch in einem geradlinig im Schiebetastenkörper 25 angeordneten Kanal 36 geführt sein, welcher erst in seinem Endbereich derart umgebogen ist, daß die in diesem Bereich aus mehreren, über Filmscharniere 39 gelenkig aneinander angebundenen Abschnitten 36 bestehende Betätigungsstange 27 mit ihrem freien Ende aus der Kontur des Schiebetastenkörpers 25 heraustritt.If this offset is to be avoided, then according to the exemplary embodiment provided in FIGS. 5a, b, the actuating rod 27 can also be guided in a channel 36 arranged in a straight line in the sliding button body 25, which is bent only in its end region in such a way that the region consists of several , Existing actuating rod 27 emerges with its free end from the contour of the sliding key body 25 via film hinges 39 articulated sections 36.
