Description

Die Erfindung betrifft ein Gurtschloß für einen Sicherheitsgurt gemäß dem Oberbegrift des Anspruchs 1.The invention relates to a belt buckle for a seat belt according to the preamble of claim 1.

Der lasttragende Rahmen von bekannten Gurtschlössern besteht üblicherweise aus einem gestanzten Blech, das um eine Mittelachse soweit gebogen wird, bis ein Ober- und ein Unterteil entstehen, die in etwa parallel zueinander, jedoch voneinander beabstandet sind. Üblicherweise sind ferner Abstandshalter am Ober- und Unterteil vorgesehen, durch die verhindert werden soll, daß die Teile einen zu geringen Abstand voneinander haben. Das gebogene Stanzteil wird anschließend vergütet. Bei der Vergütung spreizt sich der Rahmen wieder auf, und der Abstand zwischen Ober- und Unterteil vergrößert sich an deren freien Enden. Der Abstand kann so groß werden, daß der Rahmen nicht mehr zum Einbau in ein Gurtschloß geeignet ist und ein Ausschußteil darstellt. Derartige Ausschußteile müssen bei der vollautomatischen Zuführung der Einzelteile zur Montage rechtzeitig ausgesondert werden. The load-bearing frame of known buckles is made usually from a stamped sheet metal, which is about a central axis is bent until an upper and a lower part are formed, which in approximately parallel to each other, but spaced apart. Spacers are usually also on the top and bottom provided to prevent the parts from becoming too have a small distance from each other. The bent stamped part will subsequently paid. When it comes to remuneration, the framework spreads again, and the distance between the upper and lower part increases themselves at their free ends. The distance can become so large that the Frame is no longer suitable for installation in a buckle and a Represents committee part. Such committee parts must at fully automatic feeding of the individual parts for assembly on time be discarded.

Aus der gattungsgemäßen US-A-5 377 393 sind lasttragende Rahmen von Gurtschlössern bekannt, bei denen das Ober- und das Unterteil aneinander durch Niete befestigt sind, um ein Auseinanderspreizen des Rahmens zu verhindern. Das Vorsehen von Nieten zur Befestigung ist jedoch kostenintensiv.From the generic US-A-5 377 393 load-bearing frames of buckles are known, where the upper and lower parts are riveted together are attached to prevent the frame from spreading apart. However, the provision of rivets for fastening is expensive.

Die Erfindung schafft ein Gurtschloß mit einem Rahmen, bei dessen Herstellung die Gefahr der Erzeugung von zu weit auseinanderklaffenden Rahmen nahezu ausgeschlossen werden kann und der insgesamt kostengünstig herstellbar ist. Dies wird bei einem Gurtschloß der eingangs genannten Art erfindungsgemäß durch die Merkmale des Anspruchs 1 erreicht. Bei dem erfindungsgemäßen Gurtschloß geschlossen, daß sich durch eine Wärmebehandlung der Abstand zwischen dem Ober- und dem Unterteil vergrößert.The invention provides a buckle with a frame in which Manufacturing the risk of generating too wide a gap Frame can be almost excluded and the overall cost can be produced. This is at the beginning of a belt buckle mentioned type achieved according to the invention by the features of claim 1. In the belt buckle according to the invention concluded that the distance between the upper and lower part enlarged.

Der seitlich abstehende, erste Fortsatz dient zur Verbindung des Oberteils mit dem Unterteil. Der erste Fortsatz ist dabei U-förmig um einen seitlich geringfügig abstehenden, zweiten Fortsatz am anderen Teil gebogen Dieser zweite Fortsatz dient bei der bevorzugten Ausführungsform zugleich als Abstandhalter zwischen dem Ober- und Unterteil, indem er in Richtung zu dem gegenüberliegenden Teil abgewinkelt ist.The side protruding, first extension serves to connect the upper part with the Base. The first extension is U-shaped around one side slightly protruding, second extension bent on the other part This second extension serves in the preferred embodiment at the same time as a spacer between the upper and lower part by is angled towards the opposite part.

Die Fixierung des Ober- und des Unterteils aneinander kann dadurch erfolgen, daß an einem Seitenrand das Oberteil einen ersten Fortsatz und am entgegengesetzten Seitenrand das Unterteil einen ersten Fortsatz aufweist. Das entsprechende Stanzteil umfaßt bei dieser Ausführungsform vorzugsweise die gestanzten Rohlinge von mehreren Rahmen, die über die als Brückenglieder dienenden Fortsätze miteinander verbunden sind. Ein Fortsatz zwischen benachbarten Rohlingen wird nahe des einen Rohlings und ein anderer Fortsatz nahe des anderen Rohling getrennt, so daß der erste und der zweite Fortsatz an einem Seitenrand gebildet werden können. Der Abstand zwischen den benachbarten Rohlingen kann bei einem derart ausgebildeten Stanzteil sehr gering gehalten werden, was die Herstellung eines Rahmens kostengünstiger macht.This allows the upper and lower parts to be fixed to each other done that the upper part has a first extension on one side edge and on the opposite side edge the lower part a first Has extension. The corresponding stamped part includes this Embodiment preferably the punched blanks of several Frame that over the extensions serving as bridge members are interconnected. A continuation between neighboring ones Blanks become close to one blank and another extension close of the other blank separated so that the first and the second extension can be formed on one side edge. The distance between the neighboring blanks can be formed in such a stamped part be kept very low, what the manufacture of a frame makes it cheaper.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung und aus den nachfolgenden Zeichnungen, auf die Bezug genommen wird. In den Zeichnungen zeigen:

  • Figur 1 eine Draufsicht auf einen Ausschnitt eines Stanzteils, bei der zwei zusammenhängende Rohlinge für Rahmen dargestellt sind, die in einem Gurtschloß nach einer ersten Ausführungsform eingebaut werden können;

In Figur 1 ist ein Abschnitt eines Stanzteils 1 mit zwei aneinanderhängenden, gestanzten Rohlingen für lasttragende Rahmen 3, 3' gezeigt, von denen eines in das in Figur 2 dargestellte Gurtschloß 5 eingebaut ist. Jeder Rohling hat eine längliche, plattenförmige Gestalt mit einigen ausgenommenen und einigen vertieften und erhabenen Bereichen, auf die im folgenden jedoch nicht näher eingegangen wird. Die Rohlinge der Rahmen 3 sind an ihren oberen und unteren Enden durch Brückenglieder 7, 9 miteinander verbunden. Zum Trennen der Rohlinge wird das Brückenglied 7 in der Mitte in dem mit 11 gekennzeichneten Bereich getrennt, so daß an jedem Rahmen 3, 3' ein erster Fortsatz 13, 13' gebildet ist. Aus dem Brückenglied 9 wird in dessen Mitte ein Zwischenstück 15 herausgestanzt, so daß die Rahmen 3, 3' jeweils einen zweiten, im Vergleich zum ersten Fortsatz 13, 13' geringfügig, seitlich abstehenden Fortsatz 17, 17' aufweisen. Die Fortsätze 13, 13' und 17, 17' sind von einer Mittelachse 19 gleich beabstandet, so daß die Fortsätze 13, 17 und 13', 17' nach dem Biegen des Rohlings um die Mittelachse 19 übereinander angeordnet sind. Die durch das Biegen entstehenden Hälften des Rohlings bilden ein Oberteil 21 und ein Unterteil 23, die in etwa parallel zueinander, jedoch voneinander beabstandet und durch einen mittig ausgesparten Steg 25 verbunden sind. Durch die Aussparung ergibt sich eine Einführöffnung 31 für die Steckzunge eines Beschlagteils, die zwischen dem Ober- und dem Unterteil 21 bzw. 23 aufgenommen werden kann.In Figure 1 is a portion of a stamped part 1 with two contiguous, punched blanks for load-bearing frames 3, 3 'shown, one of which in the belt buckle shown in Figure 2 5 is installed. Each blank has an elongated, plate-like shape Shape with some recessed and some deepened and sublime Areas that are not discussed in more detail below. The blanks of the frame 3 are through at their upper and lower ends Bridge members 7, 9 connected to each other. For separating the blanks the bridge member 7 in the middle in the 11 marked Area separated so that on each frame 3, 3 'a first extension 13, 13 'is formed. From the bridge member 9 in the middle The intermediate piece 15 is punched out, so that the frames 3, 3 'each have one second, in comparison to the first extension 13, 13 'slightly, have laterally projecting extension 17, 17 '. The extensions 13, 13 ' and 17, 17 'are equally spaced from a central axis 19 so that the extensions 13, 17 and 13 ', 17' after bending the blank around the Center axis 19 are arranged one above the other. By bending resulting halves of the blank form an upper part 21 and Lower part 23, which are approximately parallel to each other, but from each other spaced and connected by a centrally recessed web 25 are. Through the recess there is an insertion opening 31 for the Tongue of a fitting part between the upper and the Lower part 21 or 23 can be added.

Im Bereich des dem Steg 25 gegenüberliegenden Endes des Rahmens 3 sind die zweiten Fortsätze 17 zur Festlegung des Abstands zwischen dem Ober- und Unterteil 21, 23 in Richtung zum Unterteil 23 und die ersten Fortsätze 13 in Richtung zum Oberteil 21 abgewinkelt, so daß sie aufeinander aufliegen. Die seitlich weiter nach außen abstehenden ersten Fortsätze 13 sind ferner über die zweiten Fortsätze 17 herum gebogen (vgl. Figur 2), so daß sie die zweiten Fortsätze 17 formschlüssig erfassen. Der Abstand zwischen dem Ober- und Unterteil 21 bzw. 23 ist damit stets konstant. Selbst eine Wärmebehandlung nach dem Biegen des Stanzteils 3, z.B. in Form einer Vergütung, verändert diesen Abstand nicht, so daß die Anzahl der nicht maßgenauen, da einen zu großen Abstand zwischen dem Ober- und Unterteil 21 bzw. 23 aufweisenden Rahmen sehr gering gehalten werden kann.In the region of the end of the frame 3 opposite the web 25 are the second extensions 17 for determining the distance between the Upper and lower part 21, 23 towards the lower part 23 and the first Extensions 13 angled towards the upper part 21 so that they rest on each other. The protruding laterally outwards first extensions 13 are also around over the second extensions 17 bent (see FIG. 2), so that the second extensions 17th capture positively. The distance between the top and bottom 21 or 23 is therefore always constant. Even a heat treatment after bending the stamped part 3, e.g. in the form of remuneration not this distance, so that the number of not exactly as one excessive distance between the upper and lower parts 21 and 23 having frame can be kept very low.

Der Rahmen 3 wird nach dem Biegen und dem entsprechenden Umbiegen der Fortsätze 13, 17 sowie der anschließenden Wärmebehandlung in ein Gurtschloßgehäuse 33 montiert. Übereinander angeordnete Ausnehmungen 31 (vgl. auch Figur 5) im Ober- und Unterteil 21, 23 dienen zum Vernieten des Gurtschlosses 5 an einem nicht gezeigten Befestigungsbeschlag.The frame 3 is after the bending and the corresponding bending the extensions 13, 17 and the subsequent heat treatment in one Belt buckle housing 33 mounted. Recesses arranged one above the other 31 (see also FIG. 5) in the upper and lower part 21, 23 serve for Riveting the belt buckle 5 on a not shown Attachment fitting.

Die in Figur 3 gezeigte zweite Ausführungsform eines Stanzteils 1' unterscheidet sich von der in Figur 1 gezeigten dadurch, daß die Brückenglieder 7, 9 nicht halbiert werden, sondern daß das Brückenglied 7 nahe des Rahmens 3' und das Brückenglied 9 nahe des Rahmens 3 getrennt wird, wie durch die Schneid- oder Stanzwerkzeuge symbolisierenden, schraffierten Kreise 35 angedeutet ist. Im Bereich des Seitenrandes 27 weist das Oberteil 21 den seitlich weiter abstehenden Fortsatz 13 und das Unterteil 23 den geringfügig seitlich abstehenden Fortsatz 17 auf. Dadurch wird am Seitenrand 27 der Fortsatz 13 des Oberteils 21 um den Fortsatz 17 des Unterteils 23 und im Bereich des Seitenrandes 29 der Fortsatz 13 am Unterteil 23 um den Fortsatz 17 am Oberteil 21 gebogen, wie Figur 4 zu entnehmen ist. Diese Ausgestaltung hat den Vorteil, daß im Vergleich zu der in Figur 1 gezeigten Ausführungsform kein Zwischenstück 15 aus dem Rückenteil 9 ausgestanzt werden muß. Bei gleich langen Fortsätzen 13 sind die Abstände zwischen zwei benachbarten Rahmen 3, 3' bei dem in Figur 3 gezeigten Stanzteil 1' kleiner als bei dem in Figur 1 gezeigten. Damit läßt sich insgesamt Material sparen, indem pro Stanzteil mehr Rahmen 3, 3' produziert werden können.The second embodiment of a stamped part 1 'shown in FIG. 3 differs from that shown in Figure 1 in that the Bridge members 7, 9 are not halved, but that the Bridge member 7 near the frame 3 'and the bridge member 9 near the Frame 3 is separated, as by the cutting or punching tools symbolizing, hatched circles 35 is indicated. In the area of the side edge 27, the upper part 21 has the laterally protruding extension 13 and the lower part 23 the slightly laterally projecting extension 17 on. As a result, on the side edge 27 Extension 13 of the upper part 21 around the extension 17 of the lower part 23 and in the area of the side edge 29 of the extension 13 on the lower part 23 around the Extension 17 bent on the upper part 21, as can be seen in Figure 4. This configuration has the advantage that compared to that in FIG 1 shown embodiment no intermediate piece 15 from the back part 9 must be punched out. With extensions 13 of the same length, they are Distances between two adjacent frames 3, 3 'in the in Figure 3 Stamped part 1 'shown smaller than that shown in Figure 1. In order to overall material can be saved by using more frames per stamped part 3, 3 'can be produced.

Die in Figur 6 gezeigte Ausführungsform weist anstatt der bei der in Figur 1 gezeigten Ausführungsform vorgesehenen Ausnehmungen 31 jeweils eine große, langlochartige Öffnung 31' am Ober- und am Unterteil 21, 23 auf, die bei gebogenem Stanzteil übereinander angeordnet sind. Durch die Öffnungen 31' kann das Gurtschloß über ein Gurtband oder über ein oder mehrere Seile mit dem Fahrzeug befestigt werden.The embodiment shown in Figure 6 has instead of the Recesses 31 provided in the embodiment shown in FIG. 1 each have a large, slot-like opening 31 'on the top and on Lower part 21, 23 on top of each other when the stamped part is bent are arranged. Through the openings 31 ', the belt buckle can Belt strap or attached to the vehicle via one or more ropes become.

Die in den Figuren 7 bis 9 gezeigten Ausführungsformen entsprechen weitgehend der in den Figuren 3 bis 5 in entsprechenden Ansichten gezeigten Ausführungsform. Anstatt der vier Öffnungen 31 zur Befestigung des Gurschlosses an einem Beschlag sind nur zwei langlochartige Öffnungen 31' vorgesehen, durch die auch bei diesem Gurtschloß ein Gurtband oder ein Seil gezogen werden kann, um es mit dem Fahrzeug zu verbinden. The embodiments shown in FIGS. 7 to 9 correspond largely that in Figures 3 to 5 in corresponding views shown embodiment. Instead of the four openings 31 for Fastening the buckle on a fitting is only two slot-like openings 31 'are provided through which also in this Buckle a webbing or rope can be pulled around it with to connect the vehicle.

Die zum Befestigen des Oberteils 21 mit dem Unterteil 23 vorgesehenen seitlich vorstehenden Fortsätze 13, 13', 17, 17' können bei sämtlichen Ausführungsformen unabhängig davon, mittels welcher Einrichtungen das Gurtschloß mit dem Fahrzeug verbunden ist, stets an der gleichen Position angeordnet sein, ebenso wie die als Abstandhalter dienenden Fortsätze. Dadurch können die Ober- und Unterteile von allen gezeigten Stanzteilen mit denselben Montagevorrichtungen verbunden und in das gleiche Schloßgehäuse eingebaut werden, so daß ein Modul-System entsteht, bei dem weitgehend standardisierte Einzelteile unterschiedlich miteinander kombiniert werden können.Those for fastening the upper part 21 to the lower part 23 provided laterally projecting extensions 13, 13 ', 17, 17' in all embodiments regardless of which The belt buckle is always connected to the vehicle the same position, as well as the Spacers serving extensions. This allows the top and Lower parts of all stamped parts shown with the same Assembly devices connected and in the same lock housing be installed so that a module system is created, in which largely standardized individual parts combined differently can be.
