Abstract

A belt buckle (1) for belt-band restraining systems is described, the shoulder-belt bands (8, 9) of these systems merging into the pelvic belt during their passage through the buckle. The buckle (1) consists of a buckle housing (2) having a locking mechanism and of two belt-band holding pieces (19, 20) insertable into the mechanism, separable from this at the press of a button and each provided with an inclined slot (21, 22) for the passage of the respective belt band. The holding pieces intended to bear against one another form an essentially closed bearing surface. According to the invention, the buckle (1) is characterised in that the two belt-band holding pieces (4, 5) extend, without clearance relative to the buckle housing (2), first along the insertion side (15) and then at least partially along the two longitudinal sides (17, 18) of the buckle housing, and in that the slots (21, 22) of the holding pieces are arranged at an angle of essentially 45 DEG to the central longitudinal axis (16) of the buckle and in such a way that, as seen in lateral projection, they are partially set back relative to the insertion side (15) of the buckle housing (2). <IMAGE>

Description

DieErfindung geht aus von einem Gurtschloß für Gurtband­rückhaltesysteme, bei denen die Schultergurtbänder bei ihrem Durchlauf durch das Schloß in den Beckengurt über­gehen, insbesondere für Kinderschalensitze, bestehend aus einem Schloßgehäuse mit einem Schließmechanismus und aus zwei in den Mechanismus einsteckbaren, davon auf Tasten­druck trennbaren, je mit einem geneigten Schlitz für den Durchlauf des jeweiligen Gurtbandes versehenen Gurtband-­Haltestücken, wobei die bestimmungsgemäß aneinander­liegenden Haltestücke eine im wesentlichen geschlossene Anlagefläche bilden.The invention is based on a belt buckle for webbing restraint systems in which the shoulder webbings pass into the lap belt as they pass through the buckle, in particular for child bucket seats, consisting of a buckle housing with a locking mechanism and two insertable into the mechanism, of which can be separated at the push of a button, each with an inclined slot for the passage of the respective webbing webbing holding pieces, wherein the intended abutting holding pieces form a substantially closed contact surface.

Bei den in der Praxis benutzten Gurtschlössern der vor­erwähnten Art sind die beiden Gurtband-Haltestücke so ausgebildet und in bezug auf das Schloßgehäuse angeordnet, daß sie aneinerandergelegt eine relativ kleine Körper­anlagefläche bilden und daß ihre Schlitze zur Führung der Gurtbänder ungünstig plaziert sind. Desweiteren ragen die mit dem Schloßgehäuse verbundenen Gurtband-Haltestücke von dem Schloßgehäuse sehr weit vor, so daß das Schloß insgesamt eine unbequeme Anlage am Körper der durch das Gurtbandrückhaltesystem gesicherten Person ausübt und da­bei einen unerwünschten Druck auf den Körper bewirkt. Die ungünstige Schlitzlage verhindert einen unter allen Um­ständen einwandfreien Durchlauf der Gurtbänder durch die Haltestücke.In the belt buckles of the aforementioned type used in practice, the two webbing holding pieces are designed and arranged with respect to the lock housing in such a way that they form a relatively small body contact surface when placed against one another, and that their slots for guiding the webbings are unfavorably placed. Furthermore, the webbing holding pieces connected to the lock housing protrude very far from the lock housing, so that the lock as a whole exerts an uncomfortable contact with the body of the person secured by the belt restraint system and thereby causes undesirable pressure on the body. The unfavorable slot position prevents the straps from running smoothly through the holding pieces under all circumstances.

Die Aufgabe der Erfindung besteht in der Verbesserung eines Gurtschlosses der einleitend angeführten Art dahingehend, daß das Gurtschloß bei kompaktem Aufbau im Benutzungszu­stand kein störendes Druckempfinden bewirkt und immer einen einwandfreien Durchlauf der Gurtbänder gewährleistet.The object of the invention is to improve a buckle of the type mentioned above in such a way that the buckle does not cause a disturbing sensation of pressure with a compact structure in the use state and always ensures a perfect passage of the straps.

Die Lösung dieser Aufgabe geht von dem einleitend ange­führten Gurtschloß aus und kennzeichnet sich weiter da­durch, daß sich die beiden Gurtband-Haltestücke abstands­frei zum Schloßgehäuse zunächst entlang der Steckseite und dann wenigstens teilweise entlang der beiden Längs­seiten des Schloßgehäuses erstrecken und daß die Schlitze der Haltestücke im Winkel von im wesentlichen 45° zur mittigen Schloßlängsachse und derart angeordnet sind, daß sie - in seitlicher Projektion gesehen - , gegenüber der Steckseite des Schloßgehäuses teilweise zurückversetzt sind.The solution to this problem is based on the belt buckle mentioned at the outset and is further characterized in that the two webbing holding pieces extend without clearance to the lock housing first along the plug-in side and then at least partially along the two long sides of the lock housing and in that the slots in the holding pieces are at an angle are arranged from essentially 45 ° to the central longitudinal axis of the lock and such that they - as seen in a lateral projection - are partially set back from the plug side of the lock housing.

In bevorzugter Ausbildung des erfindungsgemäßen Gurt­schlosses erstrecken sich die Gurtband-Haltestücke ent­lang den Längsseiten zwischen der halben bis zu drei Viertel der Länge der Längsseiten des Gurtschlosses. Die Schlitze der Gurtband-Haltestücke sind mit einem Drittel bis zur Hälfte ihrer Länge gegenüber der Gehäusesteckseite zurückver­ setzt angeordnet.In a preferred embodiment of the belt buckle according to the invention, the belt strap holding pieces extend along the long sides between half to three quarters of the length of the long sides of the belt buckle. The slots of the webbing holding pieces are one third to one half their length back compared to the housing plug side sets arranged.

Ein derartiges Gurtschloß hat, in Aufsicht betrachtet, ein etwa schmetterlingsförmiges Aussehen und ist somit kompakt im Aufbau, wobei trotzdem eine vergrößerte An­lagefläche durch die Gurtband-Haltestücke erzielt ist, weil diese großflächiger gestaltet sind, ohne jedoch des­wegen nach auswärts größere Abmessungen aufzuweisen. Die sich nun im wesentlichen von der mittigen Schloßlängs­achse wegerstreckenden sowie angrenzend an das und ent­lang des Schloßgehäuses erstreckenden Gurtband-Halte­stücke sind besonders für breite Gurtbänder geeignet. Durch die somit schmetterlingsförmige Umrißform des Ge­samtschlosses ergibt sich ein verringerter Anlagedruck desselben am Körper einer mit diesem Schloß gesicherten Person.Such a buckle has, when viewed from above, an approximately butterfly-like appearance and is therefore compact in construction, although an enlarged contact surface is achieved by means of the strap holding pieces, because these are designed to be larger, but without having larger dimensions outwards. The straps now extending essentially from the central longitudinal axis of the lock and extending adjacent to and along the lock housing are particularly suitable for wide straps. The butterfly-shaped outline of the entire lock thus results in a reduced contact pressure on the body of a person secured with this lock.

Weiterhin bewirkt die besondere Winkellage der Schlitze in den Gurtband-Haltestücken einen unter allen Umständen einwandfreien Durchlauf des Gurtbandes durch die Schlitze. Ein Einklemmen oder Festklemmen des Gurtbandes in den Endbereichen der Schlitze ist nun sicher vermieden. Die vorgeschlagene Schlitzlage relativ zum Schloßgehäuse und die dadurch bedingte Höheranordnung des Schloßgehäuses in bezug auf die Haltestücke ermöglicht es ferner, daß für das Schloßgehäuse mehr Spielraum für seine Montage gegeben ist, das heißt der Abstand des Schloßgehäuses zu seinem unteren Befestigungspunkt am Rückhaltesystem ist vergrößert. Somit kann die Lage des gesamten Schlosses im Rückhaltesystem und in bezug auf die zu sichernde Per­son optimiert werden.Furthermore, the special angular position of the slots in the webbing holding pieces ensures that the webbing runs smoothly through the slots under all circumstances. Pinching or clamping the belt in the end areas of the slots is now safely avoided. The proposed slot position relative to the lock housing and the resulting higher arrangement of the lock housing with respect to the holding pieces also enables the lock housing to have more scope for its assembly, that is to say the distance between the lock housing and its lower attachment point on the restraint system is increased. The position of the entire lock in the restraint system and in relation to the person to be secured can thus be optimized.

Die Erfindung ist nachstehend anhand eines in der an­liegenden, einzigen Zeichnung dargestellten Ausführungs­beispieles näher erläutert.The invention is explained below with reference to an embodiment shown in the accompanying single drawing.

Das allgemein mit 1 bezeichnete Gurtschloß besteht aus einem Schloßgehäuse 2, das den üblichen, nicht gezeigten Schloßmechanismus enthält, der mittels einer Auslöse­taste 3 entriegelt wird, und aus zwei Gurtband-Halte­stücken 4 und 5 für die Halterung und Führung eines Gurt­bandes bzw. von zwei Gurtbandabschnitten 6 und 7.The belt buckle, generally designated 1, consists of a lock housing 2, which contains the usual lock mechanism, not shown, which is unlocked by means of a release button 3, and of two belt strap holding pieces 4 and 5 for holding and guiding a belt strap or two belt strap sections 6 and 7.

Das dargestellte Gurtschloß wird in Verbindung mit solchen Gurtbandrückhaltesystemen verwendet, bei denen die Schul­tergurtbänder 8,9 bei ihrem Durchlauf durch die mit dem Schloßgehäuse 2 verriegelten Haltestücke in den Becken­gurt 10 übergehen, wie es in der Zeichnung gezeigt ist. Solche Gurtsysteme werden in der Regel in Verbindung mit Kinderschalensitzen verwendet, die in Kraftfahrzeugen benutzt werden. Der Beckengurt ist dabei durch Schlitze in dem Schalensitz geführt und verläuft dann um die Außen­seite des Schalensitzes. Alternativ können die Becken­gurtabschnitte 10 auch seitlich an dem Schalensitz be­festigt sein. Die Gurtbandabschnitte 8 und 9 verlaufen in üblicherweise weiter nach oben und bilden die Schultergurte, während das Schloßgehäuse 2 eine untere Öse 11 für die Anbringung eines gesonderten, im allge­meinen kurzen Gurtbandstückes aufweist.The belt buckle shown is used in connection with belt webbing restraint systems in which the shoulder belt straps 8, 9 pass into the lap belt 10 as they pass through the holding pieces locked with the lock housing 2, as shown in the drawing. Such belt systems are generally used in connection with child bucket seats that are used in motor vehicles. The lap belt is guided through slots in the bucket seat and then runs around the outside of the bucket seat. Alternatively, the lap belt sections 10 can also be attached laterally to the bucket seat. The webbing sections 8 and 9 usually extend further upward and form the shoulder straps, while the lock housing 2 has a lower eyelet 11 for the attachment of a separate, generally short piece of webbing.

Im gezeigten Fall hat das eine aus Kunststoff bestehende Gurtband-Haltestück 4 eine übliche, eingelassene Metall­zunge 12, die mit dem erwähnten Schließmechanismus zu­sammenwirkt, während das andere, vollständig aus Kunst­stoff bestehende Gurtband-Haltestück 5 einen Fortsatz 13 mit einem Durchgang 14 aufweist und mit dem Fortsatz auf der Zunge 12 mit Stecksitz angeordnet ist. Alternativ können aber auch beide Haltestücke 4,5 eine Zunge auf­weisen, wobei dann beide Zungen in den Schließmechanismus eingreifen.In the case shown, the one belt strap holding piece 4 made of plastic has a customary, recessed metal tongue 12 which interacts with the mentioned locking mechanism, while the other belt strap holding piece 5 made entirely of plastic has an extension 13 has a passage 14 and is arranged with the extension on the tongue 12 with a plug seat. Alternatively, however, both holding pieces 4, 5 can also have a tongue, in which case both tongues engage in the locking mechanism.

Die Gurtband-Haltestücke 4,5 sind in ihrem Umriß so gestal­tet, daß sie sich bei bestimmungsgemäßer Stecklage ab­standsfrei zum Schloßgehäuse 2 zunächst entlang der Ge­häusesteckseite 15 bzw. von der mittigen Längsachse 16 des Schlosses 1 seitlich wegerstrecken und sich dann entlang der Längsseiten 17 und 18 des Schloßgehäuses erstrecken. Im gezeigten Fall grenzt nur das Haltestück 5 steckseitig an das Gehäuse an, jedoch kann auch das andere Haltestück 4 bei entsprechender Konstruktion an die Steckseite 15 des Gehäuses 2 angrenzen, beispielsweise wenn es eine eigene Zunge aufweist.The belt strap holding pieces 4, 5 are designed in such a way that, in the intended plug-in position, they laterally extend away from the lock housing 2 along the housing plug side 15 or from the central longitudinal axis 16 of the lock 1 and then along the long sides 17 and 18 extend the lock housing. In the case shown, only the holding piece 5 adjoins the housing on the plug side, but the other holding piece 4 can also adjoin the plug side 15 of the housing 2, for example if it has its own tongue.

Vorzugsweise erstrecken sich die Haltestücke 4,5 über einen Teil der Längsseiten 17,18, und zwar über einen Abschnitt, der etwa der halben bis zu drei Viertel der Länge der Längsseiten des Schloßgehäuses 2 entspricht. Hierdurch werden Bereiche 19, 20 an den Haltestücken ausgebildet, die zusätzliche Anlageflächen zur Abstützung des ge­samten Schlosses am Körper einer Person darstellen und sich druckmindernd auswirken.The holding pieces 4, 5 preferably extend over a part of the long sides 17, 18, specifically over a section which corresponds to approximately half to three quarters of the length of the long sides of the lock housing 2. As a result, areas 19, 20 are formed on the holding pieces, which represent additional contact surfaces for supporting the entire lock on the body of a person and have a pressure-reducing effect.

Die Haltestücke 4, 5 weisen je einen üblichen Schlitz 21 bzw. 22 für den Durchlauf der Gurtbandabschnitte 6,7 auf. Diese Schlitze schließen mit der mittigen Schloß­längsachse 16 einen Winkel von im wesentlichen 45° ein, wie es in der Zeichnung gezeigt ist. Die Schlitze sind ferner so angeordnet, daß sie in bezug auf die Steckseite 15 des Gehäuses 2 zurückversetzt sind, derart, daß sie sich - in seitlicher Projektion gesehen - teilweise mit dem Schloßgehäuse decken. Diese Überdeckung beträgt vorzugs­weise ein Drittel bis zur Hälfte der Länge der Schlitze.The holding pieces 4, 5 each have a customary slot 21 or 22 for the passage of the webbing sections 6, 7. These slots form an angle of essentially 45 ° with the central longitudinal axis 16 of the lock, as shown in the drawing. The slots are further arranged so that they are set back with respect to the plug-in side 15 of the housing 2, such that - as seen in a lateral projection - they partially overlap with the lock housing. This coverage is preferably one third to half the length of the slots.

An die Schlitze 21, 22 schließen sich beidseitig nach auswärts gerichtete, vertiefte Gurtband-Führungen 23 bzw. 24 an, deren Endflächen 25 bzw. 26 in Richtung der je­weiligen Laufrichtung der betreffenden Gurtbandabschnitte 8,9; 10 verlaufen, um die Führung der Gurtbandabschnitte zu unterstützen.The slots 21, 22 are adjoined on both sides by recessed webbing guides 23 and 24, the end faces 25 and 26 of which in the direction of the respective running direction of the relevant webbing sections 8, 9; 10 run to support the guidance of the webbing sections.
