Schloss mit modifizierter Federlippe für Kraftfahrzeugtüren Lock with modified spring lip for vehicle doors
Die Neuerung betrifft ein Schloss für ein Kraftfahrzeug oder ein Gebäude, das mit einer um einen Schließbolzen drehbar im Schlossgehäuse gelagerten Drehfalle ausgerüstet ist, wobei das Schlossgehäuse eine Führungskulisse für den Schließbolzen aufweist, die einführungsseitig über mindestens eine in sie hineinreichende und den Schließbolzen abfedernde Federlippe mit deren The innovation relates to a lock for a motor vehicle or a building, which is equipped with a lock bolt rotatably mounted in the lock housing, wherein the lock housing has a guide slot for the locking bolt, the introduction side via at least one reaching into it and the locking pin cushioned spring lip their
Oberfläche teilweise abdeckendem Knarzschutz verfügt. Bei insbesondere in bewegenden Bauteilen angebrachten oder Surface partially covering Knarzschutz features. When mounted in particular in moving components or
angeordneten Schlössern kann es bei derartigen Relativbewegungen zwischen einzelnen Bauteilen zu Geräuschen kommen, die unter Komfortgesichtpunkten an sich zu vermeiden sind. Aus dem Stand der Technik sind mehrere arranged locks may cause noise in such relative movements between individual components, which are to be avoided under comfort aspects in itself. From the prior art are several
Lösungsmöglichkeiten bekannt, wie solchen Geräuschbelästigungen Possible solutions known as such noise nuisance
entgegengewirkt werden kann. Dies ist insbesondere für Kraftfahrzeuge von Bedeutung, weil bei diesen vor allem zwischen Drehfalle und Schließbolzen während der Fahrt die besagten Knarzgeräusche auftreten können. Bei der DE 102 16 313 A1 , der DE 10 2004 031 266 A1 und der DE 10 2006 028 423 A1 sind die Kontaktstellen zwischen Drehfalle und Schließbolzen mit einer can be counteracted. This is particularly important for motor vehicles, because in these especially between the catch and latch bolt while driving said creaking noise can occur. In DE 102 16 313 A1, DE 10 2004 031 266 A1 and DE 10 2006 028 423 A1, the contact points between the rotary latch and the locking bolt are with one
Dämpfungsschicht versehen, die gleichzeitig Verschleiß mindernd wirken soll. Die DE 10 2004 031 266 A1 beschreibt die Ausbildung eines Federelementes oder einer Federlippe im Schloss, über die der Schließbolzen in der Schließposition zusätzlich belastet wird. Das Federelement bzw. die Federlippe wird beim Provided damping layer, which should simultaneously reduce wear. DE 10 2004 031 266 A1 describes the design of a spring element or a spring lip in the lock, via which the locking bolt is additionally loaded in the closed position. The spring element or the spring lip is the
Einführen des Schließbolzens vorgespannt. Auch die DE 103 20 457 A1 zeigt eine solche Federlippe, die an einen Halteschenkel für den besagten Schließbolzen angespritzt sein kann. Auch bei diesen bekannten Federlippen sind die besagten Knarzgeräusche in der Schließstellung nicht ganz zu vermeiden, was schließlich bei der noch nicht veröffentlichten DE 2009 032 894.7 dann dadurch erreicht wird, dass die Federlippe mit einem Knarzschutz versehen wird. Als Knarzschutz wird ein auf die Federlippe aufgeschobenes Platten- oder Profilelement aus Metall vorgeschlagen. Der Neuerung liegt nun die Aufgabe zugrunde, die Fertigung und Montage des als Deckelement der Federlippe ausgebildeten Knarzschutzes zu Insertion of the locking bolt biased. Also, DE 103 20 457 A1 shows such a spring lip which may be molded onto a holding leg for the said locking pin. Even with these known spring lips said creaking noises in the closed position are not completely avoid what finally in the unpublished DE 2009 032 894.7 is then achieved by the spring lip is provided with a Knarzschutz. As Knarzschutz a slid on the spring lip plate or profile element made of metal is proposed. The novelty is now based on the task of manufacturing and mounting of trained as a cover element of the spring lip Knarzschutzes
vereinfachen. simplify.
Die Aufgabe wird gemäß der Neuerung dadurch gelöst, dass die Federlippe am freien Ende eine Begrenzungswulst aufweist und dass der Knarzschutz als mit Vorspannung davor auf die Federlippe aufbringbare Blechklammer ausgebildet ist. The object is achieved according to the innovation in that the spring lip has a Begrenzungswulst at the free end and that the Knarzschutz is formed as a pre-stress on the spring lip coatable sheet metal clip.
Eine derartige den Einführungsschlitz in die Führungskulisse verengende Federlippe kann auf sehr zweckmäßige und einfache Weise mit dem Knarzschutz ausgerüstet werden. Die Blechklammer wird in deren Querachse auf die Such a the insertion slot in the guide slot narrowing spring lip can be equipped in a very convenient and simple way with the Knarzschutz. The sheet metal clamp is in the transverse axis on the
Federlippe aufgeschoben, wobei sie dann eine Position einnimmt, aus der sie nicht verschoben werden kann, weil dies die Begrenzungswulst der Federlippe verhindert. Die einmal aufgeschobene Blechklammer kann also auch durch mehrfache Einführung des Schließbolzens von diesem nicht versehentlich abgeschoben werden, sondern wird daran wirksam und bleibend durch die am freien Ende der Federlippe ausgebildete Begrenzungswulst gehindert. Nach einer zweckmäßigen Ausführungsform der Neuerung ist vorgesehen, dass die Federlippe einen Sitzbereich für die Blechklammer vorgebend und in diesem Sitzbereich einen entsprechend geringeren Querschnitt aufweisend ausgebildet ist. Durch eine solche Formgebung der Federlippe wird sichergestellt, dass die Blechklammer nach dem Aufschieben nicht über die Wandung der Federlippe vorsteht, sondern vielmehr eine durchgehende Wandung erreicht ist, die ein glattes Vorbeischieben bzw. Heranschieben des Schließbolzens beim Schließvorgang des Schlosses sicherstellt. Hat der Schließbolzen seine Suspended spring lip, wherein it then occupies a position from which it can not be moved, because this prevents the Begrenzungswulst the spring lip. The once deferred sheet metal bracket can therefore not be accidentally deported by multiple insertion of the locking bolt of this, but is effectively and permanently prevented by the trained at the free end of the spring lip Begrenzungswulst. According to an advantageous embodiment of the innovation, it is provided that the spring lip is designed to have a seating area for the sheet metal clamp and a correspondingly smaller cross section in this seating area. Such a shape of the spring lip ensures that the sheet metal clip does not protrude beyond the wall of the spring lip after pushing, but rather a continuous wall is reached, which ensures a smooth passing or pushing the lock pin during the closing process of the castle. Has the locking bolt his
Endposition in der Führungskulisse eingenommen, liegen die Metalloberfläche des Schließbolzens und die der Blechklammer aufeinander, sodass die besagten Knarzgeräusche nicht oder nur geringfügig auftreten können. End position taken in the guide slot, are the metal surface of the Lock bolt and the metal clip on each other, so that said creaking noises can occur or only slightly.
Das Aufschieben der Blechklammer auf die Federlippe wird gemäß einer Weiterbildung der Neuerung dadurch erleichtert, dass die Blechklammer zwei federnd ausgebildete Flanken aufweist. Dadurch kann die Blechklammer leicht und sicher auf die Federlippe aufgeschoben werden, wobei die federnd Postponement of the sheet metal clamp on the spring lip is facilitated in accordance with a development of the innovation in that the sheet metal clamp has two resilient flanks. As a result, the sheet metal clip can be easily and safely pushed onto the spring lip, wherein the springy
ausgebildeten Flanken der Blechklammer dann dafür Sorge tragen, dass sie die einmal eingenommene Position auch sicher behält, weil die entsprechenden Flanken sich an den Korpus der Federlippe anpressen. Der sichere Sitz der Blechklammer wird dadurch noch verbessert, dass dertrained flanks of the metal clip then ensure that it also retains the position once occupied, because the corresponding flanks press against the body of the spring lip. The secure fit of the metal clip is thereby further improved that the
Sitzbereich der Blechklammer einerseits von der endseitigen Begrenzungswulst und andererseits Richtung Anschlagpunkt am Schlossgehäuse angeordneter Kante begrenzt ist. Weiter vorne ist darauf hingewiesen worden, dass der geschaffene Sitzbereich für die Blechklammer dafür sorgt, dass die Blechklammer nicht über den Querschnitt der Federlippe übersteht. Die dabei erreichte Kante sorgt dann gleichzeitig auch dafür, dass die Blechklammer nach Einnahme bzw. nach dem Überschieben im Sitzbereich eine bleibend sichere Position einnimmt. Seating area of the sheet metal clamp is bounded on the one hand by the end Begrenzungswulst and on the other hand direction stop point on the lock housing edge. Earlier it has been pointed out that the created seat area for the sheet metal clamp ensures that the sheet metal clip does not protrude beyond the cross section of the spring lip. The edge thereby achieved at the same time ensures that the sheet metal clip takes a permanently secure position after taking or after sliding over in the seating area.
Während durch den entsprechend ausgebildeten Sitzbereich ein While passing through the appropriately designed seating area
Verschieben der Blechklammer in Längsrichtung der Federlippe ausgeschlossen ist, wird auch der Sitz in Richtung Querachse dadurch optimiert, dass die Moving the sheet metal clamp in the longitudinal direction of the spring lip is excluded, the seat is also optimized in the direction of the transverse axis, that the
Blechklammer am offenen Ende beidseitig abgebogene Rastkanten aufweist. Die Flanken mit diesen Rastkanten sorgen dann gleichzeitig dafür, dass das  Sheet metal clamp has on both sides bent locking edges at the open end. The flanks with these locking edges then ensure that at the same time
Aufschieben auf die Federlippe erleichtert wird, weil die Rastkanten dazu nach außen abgebogen sind. Das Einrasten der Rastkanten einerseits und auch einen konformen Sitz imSliding on the spring lip is facilitated because the locking edges are bent to the outside. The engagement of the locking edges on the one hand and also a conforming seat in the
Bereich des Rückens der Blechkammer erreicht die Neuerung dadurch, dass die Federlippe im Sitzbereich der Blechklammer beidseitig einen Rücksprung aufweist, der am Rücken der Blechklammer der Blechdicke und am offenen Ende den Abmessungen der Rastkanten entsprechend bemessen ist. Nach der Fertigmontage sitzt die Blechklammer also dann so, dass sie an keiner Stelle über die Abmessungen der Federlippe hinausreicht, sondern genau angepasst ihren Sitz wahrnehmen kann, sodass beim Einschieben des Schließbolzen oder bei anderen Beaufschlagungen kein Verkanten oder gar Ablösen der Blechklammer zu befürchten ist. Area of the back of the sheet metal chamber reaches the novelty in that the spring lip in the seating area of the sheet metal clamp has a return on both sides, which is dimensioned at the back of the sheet metal clamp thickness and at the open end of the dimensions of the locking edges. After Final assembly sits the metal clip so then that it does not reach beyond the dimensions of the spring lip at any point, but accurately adapted to perceive their seat, so that when inserting the locking pin or other exposures no tilting or even detachment of the sheet metal clamp is to be feared.
Die Federwirkung der Flanken der Blechklammer werden die Montage begünstigend wirksam, wenn eine Flanke der Blechklammer zum offenen Ende hin schmaler werdend ausgebildet ist. Dies erleichtert das Aufschieben ohne dass ein sicherer Sitz dadurch beeinträchtigt würde. Dieses Schlankerwerden der einen Flanken erreicht man The spring action of the flanks of the sheet metal clamp are the mounting favorably effective when a flank of the sheet metal clamp is formed narrowing towards the open end. This facilitates the postponement without a secure fit would be affected. This slimmering one flank is reached
zweckmäßigerweise dadurch, dass die eine unterschiedliche Breite aufweisende Flanke im vom Rücken ausgehenden oberen Drittel die volle Breite und in den beiden restlichen Dritteln eine auf vorzugsweise auf 66 reduzierte Breite aufweist und einen mittleren Steg ergebend ausgeführt ist. Bei optimierter expediently in that the flank having a different width has the full width in the upper third proceeding from the back and the width reduced to preferably 66 in the two remaining thirds, and a middle web is produced. At optimized
Federwirkung sind so das sichere Aufschieben und das genaue Einpassen der Blechklammer in die Form der Federlippe auf jeden Fall sichergestellt. Spring effect are thus ensured the safe sliding and the exact fitting of the sheet metal clamp in the shape of the spring lip in any case.
Das sichere Abstützen des aus Metall bestehenden Schließbolzens durch die Federlippe erreicht die vorliegende Neuerung dadurch, dass die Flanke der Blechklammer mit der unverändert bis zum offenen Ende reichenden Breite auf der dem Schließbolzen zugewandten Seite der Federlippe angeordnet ist. Der eine durchgehende Breite aufweisende Teil der Blechklammer ist also auf der Seite der Federlippe angebracht und angeordnet, wo der Schließbolzen vorbei geschoben wird und wo er in seiner Endposition Kontakt zur Blechklammer bekommt. Damit ist das Ziel, nämlich die lästigen Knarzgeräusche zu vermeiden, immer sicher zu erreichen. The secure supporting of the existing metal locking bolt by the spring lip achieved the present innovation in that the edge of the sheet metal clamp is arranged with the width reaching unchanged to the open end on the side facing the locking bolt side of the spring lip. The one continuous width having part of the sheet metal clamp is thus mounted and arranged on the side of the spring lip, where the locking pin is pushed past and where he gets in its final position contact with the sheet metal clamp. Thus, the goal, namely to avoid the annoying creaking noises, always safe to reach.
Eine weitere Sicherung der einmal eingenommen Sitzposition der Another backup of the once taken seating position of the
Blechklammer an bzw. um die Federlippe ist Ziel einer Weiterbildung, wobei dies dadurch erreicht wird, dass die Federlippe im Sitzbereich des Rückens der Blechklammer eine Längsnut und die Blechklammer eine korrespondierende Sicke aufweisen. Gleichzeitig wird durch die Sicke die Blechklammer zusätzlich stabilisiert, sodass insgesamt eine optimale Positionssicherung für die auf die Federlippe aufgeschobene Blechklammer gegeben ist. Sheet clamp on or around the spring lip is the goal of a further development, this being achieved in that the spring lip in the seat portion of the back of the sheet clamp a longitudinal groove and the sheet metal clamp a corresponding bead exhibit. At the same time, the sheet metal clamp is additionally stabilized by the bead, so that overall optimum position assurance for the pushed onto the spring lip sheet clamp is given.
Hohe Standzeiten derartiger Blechklammern und gleichzeitig die Long service life of such sheet metal clamps and at the same time
notwendige Federwirkung sind dann insbesondere gegeben, wenn die necessary spring action are given in particular when the
Blechklammer neuerungsgemäß aus dünnwandigem Nirosta-Stahl gefertigt ist.  Blechklammer is made of thin-walled stainless steel according to the innovation.
Die Neuerung zeichnet sich insbesondere dadurch aus, dass für den an sich bekannten Knarzschutz eine Lösung gefunden wurde, die sich durch einfache Montage und auch Fertigung auszeichnet. Als Knarzschutz wird eine The innovation is characterized in particular by the fact that a solution was found for the Knarzschutz known per se, which is characterized by simple assembly and manufacturing. As Knarzschutz is a
Blechklammer eingesetzt, die von oben her bzw. in Richtung der Querachse der Federlippe aufgeschoben werden kann. Sie rastet dabei durch ihre Formgebung und durch die Formgebung der Federlippe so ein, dass beim weiteren Betrieb insbesondere beim Vorbeiführen und Anlegen des Schließbolzens keinerlei Gefahr besteht, dass sich die Blechklammer aus ihrer einmal eingenommen Position herausbewegt oder herausbewegen lässt. Auch bei langen Standzeiten, wie sie in der Praxis zu erwarten sind, ist der Sitz und damit immer eine genaue Kontaktaufnahme von Federlippe und Schließbolzen gegeben. Inserted sheet clamp, which can be pushed from above or in the direction of the transverse axis of the spring lip. It locks by their shape and the shape of the spring lip so that during further operation, especially when passing and applying the locking bolt there is no danger that the sheet metal clip can be moved out of their once occupied position or moved out. Even with long service life, as expected in practice, the seat and thus always an accurate contact of spring lip and locking pin is given.

Zur Sicherung dieser Position ist die Sperrklinke 4 so verschwenkt worden, dass ihre Nase 11 an der Drehfalle 2 anliegt und im Bereich einer Ausnehmung ein gezielter und genau definiert Kontaktbereich entsteht, über den ein Rückschwenken der Drehfalle 2 unterbunden ist. All diese Bauteile des Schlosses sind im Schlossgehäuse 10 angeordnet, das über eine Closed position the locking pin 3, where it can be pivoted about the pivot axis 5. To secure this position, the pawl 4 has been pivoted so that its nose 11 rests against the rotary latch 2 and in the region of a recess, a targeted and precisely defined contact area is formed over which a pivoting back of the rotary latch 2 is prevented. All these components of the castle are arranged in the lock housing 10, which has a
Führungskulisse 8 für den Schließbolzen 3 verfügt, deren Eingangsseite mit 9 bezeichnet ist. Die Drehfalle 2 ist in der Regel mit einer aus Kunststoff bestehendenGuide slot 8 for the locking pin 3 has, whose input side is designated 9. The rotary latch 2 is usually made with a plastic

Ihr Sitz ist nur durch die Locking pin 3 is generally kept free of the sheath, so that here a metal-to-metal contact may occur when the pawl 4 has fallen. The pawl 4 may have such a sheath. Not exactly indicated in the illustration of Figure 1, the position of the below-discussed spring lip 15. Its seat is only by the
strichpunktierte Linie erkennbar. dash-dotted line recognizable.
Figur 2 gibt den Sitz der Federlippe 15 innerhalb der Führungskulisse 8 wieder. Erkennbar ist, dass der Endbereich der Führungskulisse 8 einen Halbkreis bildet und dass die Federlippe 15 in diesen Halbkreis hineinreicht. Diese Figure 2 shows the seat of the spring lip 15 within the guide slot 8 again. It can be seen that the end region of the guide slot 8 forms a semicircle and that the spring lip 15 extends into this semicircle. These
Federlippe ist endseitig am Schlossgehäuse 10 festgelegt und federnd Spring lip is fixed end to the lock housing 10 and resilient
ausgebildet. Am freien Ende 18 der Federlippe 15 ist eine Ausnehmung educated. At the free end 18 of the spring lip 15 is a recess
angedeutet, die weiter hinten noch erläutert ist und die zur Aufnahme eines so genannten Knarzschutzes 17 dient, der also in diesem Bereich die Oberfläche 16 der Federlippe 15 abdeckt. hinted at, which is explained further below and the inclusion of such a Knarzschutzes 17 is used, which thus covers the surface 16 of the spring lip 15 in this area.
Erkennbar ist am freien Ende eine Begrenzungswulst 20, die das absolute Endstück der Federlippe 15 darstellt. Es fehlt in Figur 2 allerdings der so genannte Knarzschutz 17, der aus Figur 3 entnehmenbar ist. Hier ist der als Visible is at the free end a Begrenzungswulst 20, which represents the absolute end of the spring lip 15. However, FIG. 2 lacks the so-called snap guard 17, which can be seen in FIG. Here is the as
Blechklammer 21 ausgebildete Knarzschutz 17 auf den aus Figur 2 auch erkennbaren Sitzbereich 22 aufgeschoben. Nähere Einzelheiten zu dieser Sheet metal clamp trained 21 Knarzschutz 17 on the from Figure 2 also recognizable seating area 22 postponed. More details about this
Blechklammer 21 sind den weiteren Figuren zu entnehmen. Mit 26 ist der Sheet metal clamp 21 are shown in the other figures. With 26 is the
Anschlagpunkt der Federlippe 15 am Schlossgehäuse 10 gekennzeichnet. Figur 4 zeigt die Federlippe 15 in Einzeldarstellung. Erkennbar ist auch hier, dass am freien Ende 18 der Federlippe 15 eine Begrenzungswulst 20 ausgebildet ist, die zusammen mit der Kante 27 nach dem Aufschieben der Blechklammer 21 dafür Sorge trägt, dass diese den einmal eingenommen Sitz auch bei Attachment point of the spring lip 15 marked on the lock housing 10. Figure 4 shows the spring lip 15 in an individual representation. It can be seen here that at the free end 18 of the spring lip 15 a Begrenzungswulst 20 is formed, which together with the edge 27 after pushing the sheet metal clamp 21 ensures that this once occupied the seat even at
entsprechender Belastung durch den Schließbolzen 3 beibehält. Zum leichteren Montieren also Aufschieben der Blechklammer 21 ist diese mit zwei federnd ausgebildeten Flanken 24, 25 ausgestattet, wobei am Ende dieser Flanken 24, 25, also am offenen Ende 28 der Blechklammer 21 corresponding load by the locking pin 3 maintains. To facilitate mounting so pushing on the sheet metal clamp 21, this is equipped with two resilient flanks 24, 25, wherein at the end of these flanks 24, 25, ie at the open end 28 of the sheet metal clamp 21st
Rastkanten 29, 30 ausgebildet sind. Deren genaue Ausbildung ist Figur 6 zu entnehmen, woraus deutlich zu entnehmen ist, dass diese nach außen so abgebogen sind, dass dadurch das Aufschieben der Blechklammer 21 auf die Federlippe 15 im Sitzbereich 22 erheblich erleichtert ist. Stop edges 29, 30 are formed. Their exact training is shown in Figure 6, from which it can be clearly seen that they are bent outwardly so that thereby the sliding of the sheet metal clamp 21 on the spring lip 15 in the seating area 22 is greatly facilitated.
Eine besondere Ausbildung der Blechklammer 21 ist den Figuren 6 und 7 zu entnehmen. Einmal ist eine Flanke 24 durchgehend breit ausgebildet, während die andere Flanke 25 im oberen Drittel 35 die gleiche Breite aufweist, in den beiden restlichen Dritteln 36 aber schmaler ausgebildet ist, wobei ein Steg 37 entsteht, der die Federkraft für das Aufschieben begünstigend wirkt. A special embodiment of the sheet metal clamp 21 is shown in FIGS. 6 and 7. Once a flank 24 is continuously wide, while the other edge 25 in the upper third 35 has the same width, but is narrower in the two remaining thirds 36, wherein a web 37 is formed, which acts favoring the spring force for pushing.
Schon erwähnt worden ist, dass Figur 4 die Federtippe 15 zeigt, bevor die Blechklammer 21 aufgeschoben worden ist. Erkennbar sind dabei ein oberer Rücksprung 32 und ein unterer Rücksprung 33. Erreicht wird dadurch eine g durchgehende Gleitfläche 31 für den Schließbolzen 3, wenn er während des Schließvorganges des Schlosses 1 an der Federlippe 15 entlang und durch diese geführt in die Führungskulisse 8 und dann das Einlaufmaul 7 der Drehfalle 2 eingeschoben wird. Durch die Rücksprünge 32, 33 sowie den reduzierten Querschnitt im Sitzbereich 22 wird erreicht, dass der Schließbolzen 3 ohne Beeinträchtigung an der Federlippe 15 entlang geschoben wird, wobei diese Federlippe 15 eng anliegt und dafür Sorge trägt, dass der Schließbolzen 3 an die Wandung der Drehfalle 2 herangeführt und an sie angelegt wird. It has already been mentioned that FIG. 4 shows the spring tippet 15 before the sheet metal clamp 21 has been pushed open. Recognizable are an upper recess 32 and a lower recess 33. This is achieved by a g continuous sliding surface 31 for the locking pin 3, when it is inserted during the closing operation of the lock 1 along the spring lip 15 and guided by this in the guide slot 8 and then the inlet mouth 7 of the rotary latch 2. By the recesses 32, 33 and the reduced cross-section in the seating area 22 it is achieved that the locking bolt 3 is slid along the spring lip 15 without interference, this spring lip 15 resting tightly and ensuring that the locking bolt 3 bears against the wall of the rotary latch 2 and applied to them.
Figur 7 schließlich zeigt einen Schnitt durch die Federlippe 15 im Finally, FIG. 7 shows a section through the spring lip 15 in FIG
Sitzbereich 22 der Blechklammer 21 , wobei erkennbar wird, dass im Rücken 34 der Federlippe 15 eine Längsnut 39 vorgesehen ist. Diese Längsnut 39 ist in die Oberkante 40 der Federlippe 15 eingeschnitten. Korrespondierend dazu ist eine Sicke 41 in der Blechklammer 21 ausgebildet. Ein genauer und vor allem genau bleibender Sitz der Blechklammer 21 ist durch diese besondere Ausbildung zusätzlich gewährleistet, wobei noch einmal abschließend darauf hingewiesen wird, dass die dem Schließbolzen 3 zugewandte Seite 38 der Blechklammer 21 diejenige mit der durchgehenden Flanke 24 ist. Seating area 22 of the sheet metal clamp 21, wherein it can be seen that in the back 34 of the spring lip 15, a longitudinal groove 39 is provided. This longitudinal groove 39 is cut into the upper edge 40 of the spring lip 15. Corresponding thereto, a bead 41 is formed in the sheet metal clamp 21. An accurate and above all, exactly permanent seat of the sheet metal clamp 21 is additionally ensured by this special training, being again pointed out that the locking pin 3 facing side 38 of the sheet metal clamp 21 is the one with the continuous edge 24.
