Description

Die Erfindung bezieht sich auf eine Verglasungsdichtung aus elastischem Kunststoff mit einem als Hohlprofil ausgebildeten Kopfbereich und einem sich anschließenden Fußbereich zum Verankern der Verglasungsdichtung in einer Haltenut eines Rahmens oder eines Flügels eines Fensters, einer Türe oder dgl., wobei Kopfbereich und Fußbereich über einen Profilrücken miteinander verbunden sind, der Kopfbereich auf seiner dem Profilrücken gegenüberliegenden Seite einen aus einem oberen und einem unteren Schenkel bestehenden Außensteg umfaßt, der an seinem oberen Ende über einen Verbindungssteg mit dem oberen Ende des Profilrückens verbunden ist und an seinem unteren Ende in einen Quersteg einmündet, der über einen in einem Abstand zum Profilrücken hin versetzt in ihn einlaufenden Stützsteg mit dem Profilrücken verbunden ist und über die Einmündestelle des unteren Schenkels des Außensteges hinaus weiterläuft, und wobei ferner die beiden Schenkel des Außensteges bei Dichteingriff zueinander verschwenkbar miteinander verbunden sind, wobei im unbelasteten Zustand der Verglasungsdichtung der vom Verbindungssteg aus laufende obere Schenkel des Außensteges zu dessen unterem Schenkel hin vom Profilrücken unter einem spitzen Winkel abspreizt.The invention relates to a glazing gasket made of elastic plastic with a trained as a hollow profile head portion and a subsequent foot area for anchoring the glazing gasket in a retaining groove of a frame or a wing of a window, a door or the like., The head and foot area via a profile back with each other are connected, the head region on its side opposite the profile back comprises an upper and a lower leg outer web which is connected at its upper end via a connecting web to the upper end of the profile back and opens at its lower end in a transverse web, the about an offset at a distance from the back of the profile in him incoming support web is connected to the profile back and continues beyond the Einmündestelle the lower leg of the outer web out, and further wherein the two legs of the outer web at density iff are mutually pivotally connected to each other, wherein in the unloaded state of the glazing gasket of running from the connecting web of the upper leg of the outer web to the lower leg from the profile back spreads at an acute angle.

Eine Verglasungsdichtung dieser Art wird in der DE 197 14 465 C1 beschrieben. Bei diesem bekannten Verglasungsprofil dient der obere Schenkel des Außensteges des Kopfbereiches als Dichtsteg, der bei Dichteingriff von der abzudichtenden Gegenfläche aus seiner im unbelasteten Zustand vom Dichtrücken abspreizenden Lage in Richtung auf den Dichtrücken verschwenkt wird. Führt diese Verschwenkung dazu, daß dieser obere Schenkel eine parallel zum Dichtrücken verlaufende Verschwenklage einnimmt, dann liegt er mit seiner ganzen planen Außenfläche gegen die abzudichtende Gegenfläche an, wodurch die maximale Dichtwirkung erreicht wird.A glazing gasket of this type is used in the DE 197 14 465 C1 described. In this known glazing profile, the upper leg of the outer web of the head portion serves as a sealing ridge, which is pivoted in sealing engagement of the counter surface to be sealed from its in the unloaded state from the sealing ridge spreading position in the direction of the sealing back. Leads to this pivoting that this upper leg assumes a parallel to the sealing ridge Verschwenklage, then he lies with his entire flat outer surface against the sealed counter surface, whereby the maximum sealing effect is achieved.

Solange dieser obere Schenkel des Außensteges jedoch noch nicht in die parallele Ausrichtung zum Profilrücken gebracht ist, findet an seiner Außenfläche ein Kontakt mit der abzudichtenden Gegenfläche nur über einen relativ kleinen Kontaktbereich hinweg statt, was gerade bei einer etwas größeren Toleranz des abzudichtenden Spaltes nicht immer zu einer voll zufriedenstellenden Dichtwirkung führt. Die Toleranzaufnahme, welche den Bereich zwischen dem unteren Ende des oberen Schenkels des Außensteges im unbelasteten Zustand der Dichtung und der Verkippung des unteren Schenkels parallel zum Profilrahmen umfaßt, ist bei in der Praxis auftretenden Toleranzen in der Spaltweite nicht immer ausreichend. Auch besteht dabei die Gefahr, daß bei einem nur relativ kleinen Berührungsbereich zwischen Dichtsteg und abzudichtender Gegenfläche und dem dabei vorliegenden spitzwinkeligen Anstellwinkel des Dichtsteges dieser gegenüber von außen Wasser oder auch Verschmutzung in den Dichtspalt, bei ungünstigen Bedingungen, eintreten kann.As long as this upper leg of the outer bar is not yet brought into the parallel alignment with the profile back, takes place on its outer surface contact with the sealed counter surface only over a relatively small contact area away, which is not always with a slightly larger tolerance of the gap to be sealed a fully satisfactory sealing effect leads. The tolerance recording, which the area between the lower end of the upper leg of the outer web in the unloaded state of the Includes seal and the tilting of the lower leg parallel to the profile frame is not always sufficient in practice occurring tolerances in the gap width. There is also the risk that with only a relatively small contact area between the sealing land and sealed counter surface and the present acute angle of attack of the sealing web of this opposite from the outside water or pollution in the sealing gap, under unfavorable conditions, can occur.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine solche Verglasungsdichtung vorzuschlagen, die über einen größeren Toleranzbereich hinweg, auch bei relativ großen Spalttoleranzen, eine sehr gute Abdichtwirkung zeigt und gleichzeitig das unerwünschte Eindringen von Feuchtigkeit besser verhindert. Außerdem soll die erfindungsgemäße Verglasungsdichtung auch mit relativ geringen Schließkräften einsetzbar sein.Proceeding from this, the object of the invention is to propose such a glazing gasket which exhibits a very good sealing effect over a larger tolerance range, even with relatively large gap tolerances, and at the same time better prevents the undesired penetration of moisture. In addition, the glazing gasket according to the invention should also be usable with relatively low closing forces.

Erfindungsgemäß wird dies bei einer Verglasungsdichtung der einleitend genannten Art dadurch erreicht, daß der Quersteg ein schräg zum Profilrücken verlaufender Dichtsteg ist, der mit seinem über die Einmündestelle des unteren Schenkels des Außensteges vorstehenden Stegabschnitt bei Dichteingriff zur Anlage gegen die dem Profilrücken abgewandte Außenseite des unteren Schenkels des Außensteges verschwenkbar ist, angenähert gleich lang wie der untere Schenkel des Außensteges ausgebildet ist und mit diesem einen spitzen Winkel einschließt, und daß der untere Schenkel des Außensteges mit dem Dichtsteg über einen bogenförmig gerundeten Zwischenabschnitt verbunden ist, der auf seiner dem Profilrücken abgewandten Seite tangential und auf seiner dem Profilrücken zugewandten Seite annähernd senkrecht in den Dichtsteg einläuft, daß ferner die beiden Schenkel des Außensteges über einen Zwischensteg miteinander verbunden sind, der angenähert rechtwinklig vom unteren Ende des oberen Schenkels in Richtung zum Profilrücken hin abläuft und eine Länge aufweist, die auf seiner dem Profilrücken abgewandten Außenseite angenähert der Dicke des vorstehenden Abschnitts des Dichtsteges entspricht, und daß ferner das freie Ende des Dichtsteges, im unbelasteten Zustand der Verglasungsdichtung, weiter vom Profilrücken absteht als das untere Ende des oberen Schenkels des Außensteges.According to the invention this is achieved in a glazing gasket of the aforementioned type, characterized in that the crosspiece is an obliquely to the profile backs sealing web, with its over the junction of the lower leg of the outer web projecting web portion in sealing engagement to rest against the back of the profile back outside of the lower leg the outer web is pivotable, approximately the same length as the lower leg of the outer web is formed and with this forms an acute angle, and that the lower leg of the outer web is connected to the sealing land via an arcuately rounded intermediate portion, the tangential on its side facing away from the profile back and approximately perpendicularly enters the sealing web on its side facing the profile back, that further the two legs of the outer web are connected to each other via a gutter, which approximately at right angles from the lower end of the upper leg runs in the direction of the profile back and has a length which corresponds approximately to the outer side facing away from the profile back of the thickness of the projecting portion of the sealing web, and further that the free end of the sealing web, in the unloaded state of the glazing gasket, further protrudes from the profile back as the lower end of the upper leg of the outer bridge.

Bei der erfindungsgemäßen Verglasungsdichtung wird zunächst unterhalb des unteren Schenkels des Außensteges ein schräg zum Profilrücken verlaufender Dichtsteg eingesetzt, in den der untere Schenkel des Außensteges einmündet, wobei der über die Einmündestelle des unteren Schenkels des Außensteges vorstehende Abschnitte dieses Dichtsteges bei Dichteingriff von der abzudichtenden Gegenfläche gegen die dem Profilrücken abgewandte Außenseite des unteren Schenkels des Außensteges verschwenkt wird, gegen die er schließlich zur Anlage kommt. Dieses Verklappen des vorstehenden Dichtsteges gegen die Außenseite des unteren Schenkels des Außensteges findet zu Beginn des Dichteingriffes statt, wobei sich bei diesem Verschwenken des Dichtsteges zunächst der Hohlquerschnitt des Kopfbereiches der Verglasungsdichtung noch so gut wie nicht mit deformiert. Erst wenn der Dichtsteg gegen die Außenseite des unteren Schenkels angelegt ist und der Schließvorgang weitergeführt wird, wird dann zunehmend auch noch das Hohlprofil des Kopfbereiches in Richtung auf den Profilrücken hin eingedrückt, wodurch die Außenseite des oberen Schenkels des Außensteges ebenfalls zunehmend in Anlagekontakt mit der Gegenfläche gebracht wird. Da aber bei diesem Vorgang die ganze Außenfläche des unteren Dichtsteges bereits vollständig in Anlage an der abzudichtenden Gegenfläche anliegt, wird bei der erfindungsgemäßen Verglasungsdichtung beim Schließvorgang schon sehr bald ein relativ großer Dichtbereich geschaffen, der dann noch zusätzlich durch einen weiteren, an der Außenseite des oberen Schenkels des Außensteges sich ausbildenden zusätzlichen Anlagebereich mit der abzudichtenden Gegenfläche verstärkt wird. Dadurch, daß bei der erfindungsgemäßen Verglasungsdichtung das freie Ende des Dichtsteges, im unbelasteten Zustand der Dichtung, weiter vom Profilrücken absteht als das ebenfalls von diesem schräg vorstehende untere Ende des oberen Schenkels, ist beim Schließvorgang sichergestellt, daß die abzudichtende Gegenfläche in jedem Fall zuerst mit der vorspreizenden Dichtlippe in Kontakt gelangt und auch diese zunächst einklappt, bevor sie gegen das untere Ende des oberen Schenkels anläuft und ab diesem Zeitpunkt dann nicht nur den letzteren ebenfalls in Richtung auf den Profilrücken hin verklappt, sondern dabei auch das ganze Hohlprofil des Kopfbereiches der Dichtung deformiert.In the case of the glazing gasket according to the invention, a sealing web extending obliquely to the profile back is first inserted below the lower leg of the outer web, into which the lower leg of the outer web opens, the sections of this sealing web projecting beyond the junction of the lower leg of the outer web against the counter surface to be sealed against the sealing surface the outer side facing away from the profile back of the lower leg of the outer web is pivoted against which he finally comes to the plant. This folding of the projecting sealing web against the outside of the lower leg of the outer web takes place at the beginning of the sealing engagement, wherein at this pivoting of the sealing web initially the hollow cross section of the head portion of the glazing gasket is not deformed as well. Only when the sealing ridge is applied against the outside of the lower leg and the closing process is continued, then also increasingly the hollow profile of the head portion is pressed in the direction of the profile back out, whereby the outside of the upper leg of the outer web also increasingly in abutting contact with the counter surface is brought. Since, however, in this process, the entire outer surface of the lower sealing ridge already fully rests in abutment against the counter surface to be sealed, a relatively large sealing area is created in the glazing gasket according to the invention during the closing very soon, then in addition by another, on the outside of the upper Leg of the outer web forming additional investment area is reinforced with the counter-surface to be sealed. Due to the fact that in the glazing gasket according to the invention, the free end of the sealing web, in the unloaded state of the seal, protrudes further from the profile back than also obliquely projecting from this lower end of the upper leg, during the closing process ensures that the sealed counter surface in each case first with the vorspreizenden sealing lip comes into contact and this folds first before it starts against the lower end of the upper leg and then from this point not only the latter also folded in the direction of the profile back out, but also the whole hollow profile of the head portion of the seal deformed.

Der unterhalb des unteren Schenkels des Außensteges schräg nach oben vorragende Dichtsteg stellt, auch bei Dichteingriff, sicher, daß unter ungünstigen Bedingungen von außen eintretende Feuchtigkeit nicht über diesen Dichtsteg weiter in das Innere des abzudichtenden Spaltes hineinlaufen kann, da es innerhalb des vom schräg nach oben vorspringenden Dichtsteg einerseits und der Außenseite des unteren Schenkels andererseits gebildeten Aufnahmeraum aufgenommen wird.The below the lower leg of the outer ridge obliquely upwardly projecting sealing ridge, even with sealing engagement, ensure that under unfavorable conditions from the outside entering moisture can not run through this sealing ridge further into the interior of the gap to be sealed, as it is within the obliquely upward projecting sealing ridge on the one hand and the outside of the lower leg on the other hand formed receiving space is added.

Beim Schließvorgang treten gerade in dessen anfänglichem Abschnitt, bei dem die abzudichtende Gegenfläche gegen den vorspringenden Dichtsteg anläuft und diesen zunächst allein gegen die Außenseite des unteren Schenkels verschwenkt, nur relativ geringe Schließkräfte auf, die erst dann etwas stärker werden, wenn bei einem noch fortgesetzten Schließen anschließend auch die beiden Schenkel des Außensteges und damit der gesamte Kopfbereich deformiert werden. Da bei dieser Deformation des Kopfbereiches jedoch keiner der beiden Schenkel des Außensteges bei deren Verschwenken in Richtung des Profilrückens gegenüber diesem abgestützt wird, sind die dabei auftretenden Schließkräfte noch immer geringer als bei der gattungsgemäßen Verglasungsdichtung.During the closing process occur only in the initial section, in which the sealed counter surface starts against the projecting sealing ridge and this initially pivoted alone against the outside of the lower leg, only relatively small closing forces, which only then become somewhat stronger, if in a still continued closing Subsequently, the two legs of the outer web and thus the entire head area are deformed. However, in this deformation of the head area, neither of the two legs of the outer web when pivoting in the direction of the profile back is supported against this, the closing forces are still lower than in the generic glazing gasket.

Die Ausbildung der Verbindung des unteren Schenkels des Außensteges mit dem Dichtsteg über einen bogenförmig gerundeten Zwischenabschnitt, der auf seiner Oberseite tangential in den Dichtsteg einläuft und auf seiner dem Profilrücken zugewandten Unterseite annähernd senkrecht in diesen Dichtsteg einmündet, schafft eine Gelenkstelle, die das Verschwenken des überstehenden Dichtabschnitts gegen die Außenfläche des unteren Schenkels des Außensteges begünstigt.The formation of the connection of the lower leg of the outer web with the sealing web over an arcuately rounded intermediate portion, which enters tangentially into the sealing web on its upper side and opens approximately vertically in this sealing web on its underside facing the profile back, creates a hinge point, the pivoting of the protruding Sealing section against the outer surface of the lower leg of the outer web favors.

Die angenähert gleiche Länge des überstehenden Bereiches des Dichtsteges und des unteren Schenkels des Außensteges führt auch dazu, daß im eingeklappten Zustand der Dichtsteg bei seiner Anlage gegen die Außenseite des unteren Schenkels nicht mit dem unteren Ende des oberen Schenkels des Außensteges kollidiert. Dabei ist durch die Ausgestaltung des Zwischensteges, der den oberen und den unteren Schenkel des Außensteges miteinander verbindet, derart, daß er an seiner Außenseite angenähert der Dicke des vorstehenden Abschnitts des Dichtsteges entspricht, zudem gewährleistet, daß der Dichtsteg im eingeklappten Zustand auch nicht nach außen hin über die Lage des unteren Endes des oberen Schenkels des Außensteges hinausragt, was im Interesse der Ausbildung guter Dichtverhältnisse günstig ist.The approximately same length of the projecting portion of the sealing web and the lower leg of the outer web also causes the sealing web in its folded against the outside of the lower leg does not collide with the lower end of the upper leg of the outer web in the folded state. In this case, by the configuration of the intermediate web, which connects the upper and the lower leg of the outer web with each other, such that it approximately corresponds to the outside of the thickness of the protruding portion of the sealing web on its outer side, also ensures that the sealing web in the folded state and not to the outside extends beyond the position of the lower end of the upper leg of the outer web, which is favorable in the interest of training good sealing conditions.

Die erfindungsgemäße Verglasungsdichtung verfügt bezüglich der Größe des abzudichtenden Spaltes über eine sehr große Toleranzaufnahme bei gleichzeitig sehr guter Abdichtwirkung, und dies in Verbindung mit geringen Schließkräften. Dabei wird in der Dicht-Endlage eine relativ großflächige Anlage am Rahmen des Fensters o. ä. erreicht.With regard to the size of the gap to be sealed, the glazing gasket according to the invention has a very large tolerance pickup and at the same time a very good sealing effect, and this in conjunction with low closing forces. In this case, a relatively large-scale system on the frame of the window o. Ä. Is achieved in the sealing end position.

Die Lage des an der Unterseite des Kopfbereiches schräg vorspringenden Dichtsteges gestattet in dieser Anordnung auch die Möglichkeit eines störungsfreien Eindrehens auf der Bandseite.The position of the obliquely projecting at the bottom of the head area sealing bar allows in this arrangement, the possibility of trouble-free screwing on the hinge side.

In einer vorteilhaften Ausgestaltung der erfindungsgemäßen Verglasungsdichtung läuft am oberen Ende des Profilrückens eine Dichtzunge schräg ab, welche auf die dem Hohlprofil des Kopfbereiches abgewandte Rückseite des Profilrückens hin geneigt vorspringt. Durch diese auf die Rückseite des Profilrückens geneigte Dichtzunge wird erreicht, daß beim Einbau der Verglasungsdichtung oben an deren Rückseite diese Dichtzunge elastisch gegen das abzudichtende Fenster angedrückt wird und damit ein Eindringen von Feuchtigkeit von dieser Oberseite her zwischen dem Profilrücken und der Fensterscheibe verhindert wird.In an advantageous embodiment of the glazing gasket according to the invention runs at the upper end of the profile back a sealing tongue from obliquely, which projects inclined towards the rear side of the profile back facing away from the hollow profile of the head region. By this inclined to the back of the profile back sealing tongue is achieved that when installing the glazing gasket at the top of the back of this sealing tongue is pressed elastically against the sealed window and thus penetration of moisture from this top between the profile back and the window is prevented.

Weiterhin ist es bei der Erfindung von besonderem Vorteil, wenn in Höhe des oberen Schenkels des Außensteges des Kopfbereiches auf der Rückseite des Profilrückens ein Klebestreifen zum Aufkleben des Profilrückens an der ebenen Fenster-Gegenfläche angebracht ist. Dabei wird dieser Klebestreifen untrennbar an der Rückseite des Profilrückens befestigt, z. B. verschweißt, wodurch eine dauerhafte, untrennbare Verbindung zwischen beiden entsteht.Furthermore, it is in the invention of particular advantage, when attached at the level of the upper leg of the outer web of the head portion on the back of the profile back an adhesive strip for adhering the profile back to the flat window mating surface. In this case, this tape is inseparably attached to the back of the profile back, z. B. welded, creating a permanent, inseparable connection between the two.

Eine weitere sehr vorteilhafte Ausgestaltung der erfindungsgemäßen Verglasungseinrichtung besteht auch darin, daß entlang der dem Profilrücken zugewandten Innenseite des oberen Schenkels des Außensteges ein von diesem vorspringender elastischer, im Querschnitt etwa rechteckförmiger Auflageblock angebracht ist, dessen Dicke so gewählt ist, daß bei Dichteingriff bei Vorliegen eines Dichtspaltes in Nenn-Größe, wenn nämlich der obere Schenkel des Außensteges parallel zum Profilrücken verkippt ist, zwischen den einander zugewandten Flächen von Auflageblock und Profilrücken noch kein Kontakt, sondern noch ein freier Spalt von 2/10 mm bis 3/10 mm gebildet wird. Besonders bevorzugt besteht dabei der Auflageblock aus einem geeigneten geschäumten Kunststoffmaterial, etwa einem geeigneten TPE (thermoplastisches Polyethylen). Wenn der Einbauspalt der Nenn-Spaltweite, z. B. 5,5 mm, entspricht, besteht somit noch ein sehr kleiner Restspalt zwischen den einander zugewandten Flächen von Auflageblock und Profilrücken. Dadurch besteht die Möglichkeit, falls der Spalt etwas kleiner als die Nennweite ist, also etwa nur 5,0 mm beträgt, daß beim Einbau der Verbindungssteg zwischen dem oberen Ende des Außensteges und dem oberen Ende des Profilrückens sich in seinem mittleren Erstreckungsbereich etwas nach außen hin auswölben kann, so daß die damit einhergehende kleine Kompression des Dichtungskopfes noch ermöglicht ist, bevor der Auflageblock mit seiner frei vom oberen Schenkel vorragenden Endfläche gegen die zugewandte Fläche des Profilrückens zur Anlage kommt. Läge hier schon vorher eine Anlage zwischen beiden Elementen vor, nämlich wenn die erfindungsgemäße Verglasungsdichtung in einem Nenn-Dichtspalt montiert wäre, würde bei einer Toleranz des Dichtspaltes im Sinne eines Untermaßes eine sehr hohe Andruckkraft erforderlich werden, um die dann nötige Kompression des Dichtungskopfes zu bewirken, weil dann auch der Auflageblock noch einmal in Gänze komprimiert werden müßte.Another very advantageous embodiment of the glazing device according to the invention also consists in that along the profile back facing inside of the upper leg of the outer web of this projecting elastic, in cross-section approximately rectangular support block is mounted, whose thickness is chosen so that in sealing engagement in the presence of a Sealing gap in nominal size, namely, when the upper leg of the outer web is tilted parallel to the profile back, between the facing surfaces of support block and profile back still no contact, but still a free gap of 2/10 mm to 3/10 mm is formed. Particularly preferably, the support block consists of a suitable foamed plastic material, such as a suitable TPE (thermoplastic polyethylene). If the mounting gap of the nominal gap width, z. B. 5.5 mm, corresponds, so there is still a very small residual gap between the facing surfaces of support block and profile back. This makes it possible, if the gap is slightly smaller than the nominal size, that is about 5.0 mm, that during installation of the connecting web between the upper end of the outer web and the upper end of the profile back slightly outwardly in its central extent range can bulge, so that the associated small compression of the sealing head is still possible before the support block comes with its free from the upper leg projecting end surface against the facing surface of the profile back to rest. If there were already an installation between the two elements, namely if the glazing gasket according to the invention were mounted in a nominal sealing gap, a very high pressure force would be required for a tolerance of the sealing gap in the sense of undersize in order to effect the then necessary compression of the sealing head because then also the support block would have to be compressed once again in total.

Dabei ist es besonders bevorzugt, wenn der Verbindungssteg zwischen dem oberen Ende des Außensteges und dem oberen Ende des Profilrückens in seinem mittleren Erstreckungsbereich, in dem er sich bei Untermaß des Einbauspaltes nach außen wölben kann, mit einer reduzierten Wanddicke versehen wird, so daß die dabei aufzubringenden Kräfte geringer werden.It is particularly preferred if the connecting web between the upper end of the outer web and the upper end of the profile back in its central extension region, in which he can bulge outwards at undersize of the mounting gap, is provided with a reduced wall thickness, so that the case be reduced forces.

Die Schräge des Dichtsteges im unbelasteten Zustand der Verglasungsdichtung kann in jedem geeigneten Winkel erfolgen, wird aber ganz besonders bevorzugt so ausgeführt, daß er im Bereich von 40° bis 50°, besonders bevorzugt bei 45°, schräg zum Profilrücken geneigt verläuft.The slope of the sealing web in the unloaded state of the glazing gasket can be done at any suitable angle, but is most preferably carried out so that it is inclined in the range of 40 ° to 50 °, more preferably at 45 °, inclined to the profile back.

Es ist ferner von Vorteil, wenn der Dichtsteg auf seiner dem Profilrücken abgewandten Außenseite plan ausgebildet ist, wodurch die Ausbildung einer relativ großen Kontaktfläche mit der abzudichtenden Gegenfläche erreicht wird.It is also advantageous if the sealing web is formed flat on its outer side facing away from the profile back, whereby the formation of a relatively large contact surface with the counter surface to be sealed is achieved.

The invention will now be explained in more detail by way of example with reference to the drawings in principle. Show it:

Fig. 3

Fig. 4

In Fig. 1 ist ein Querschnitt durch eine im vergrößerten Maßstab dargestellte Verglasungsdichtung 1 gezeigt, die in Form einer Strangdichtung aus einem geeigneten elastischen Kunststoff, etwa einem SEBS (Styrol-Ethylen-Butadien-Styrol-Elastomer) gefertigt ist.In Fig. 1 Fig. 3 is a cross-section through an enlarged scale glazing gasket 1 made in the form of a strand seal made of a suitable elastic plastic, such as a SEBS (styrene-ethylene-butadiene-styrene elastomer).

Diese Verglasungsdichtung 1 weist einen oberen Kopfbereich 2 und einen unteren Fußbereich 3 auf, die über einen Profilrücken 4 miteinander verbunden sind. Die Ausdrücke "oben" bzw. "oberer" bezeichnen im Rahmen der hier gegebenen Ausführungen eine kopfseitige Lage bzw. die Kopfseite der Verglasungsdichtung 1 und "unten" bzw. "unterer" eine fußseitige Lage bzw. die Fußseite der Verglasungsdichtung 1.This glazing gasket 1 has an upper head area 2 and a lower foot area 3, which are connected to one another via a profile back 4. The terms "upper" and "upper" designate in the context of the embodiments given here a head-side layer or the head side of the glazing gasket 1 and "bottom" or "lower" a foot-side layer or the foot side of the glazing gasket. 1

Der Kopfbereich 2 ist als Hohlprofil ausgebildet, und am Fußbereich 3 ist z. B. eine verdickte Halterippe 13 zum Verankern der Verglasungsdichtung 1 in einer Haltenut 14 eines Flügels 16 eines Fensters o. ä. angebracht (vgl. Darstellung der Fig. 2A).The head portion 2 is formed as a hollow profile, and at the foot region 3 is z. B. a thickened retaining rib 13 for anchoring the glazing gasket 1 in a retaining groove 14 of a wing 16 of a window o. Ä. Attached (see Fig. 2A ).

Der Kopfbereich 2 der Verglasungsdichtung 1 umfaßt zunächst einen Abschnitt des Profilrückens 4, dem im Kopfbereich 2 ein Außensteg 5 gegenüberliegt, der seinerseits einen oberen Schenkel 5A sowie unter diesem einen unteren Schenkel 5B aufweist.The head portion 2 of the glazing gasket 1 initially comprises a portion of the profile back 4, the head portion 2 opposite an outer web 5, which in turn has an upper leg 5A and below this a lower leg 5B.

Der Außensteg 5 ist an seinem oberen Ende, also am oberen Ende des oberen Steges 5A, über einen Verbindungssteg 6 mit dem vom Fußbereich 3 abgewandten oberen Ende des Profilrückens 4 verbunden.The outer web 5 is connected at its upper end, ie at the upper end of the upper web 5A, via a connecting web 6 with the upper end of the profile back 4 facing away from the foot region 3.

Der obere Schenkel 5A und der untere Schenkel 5B des Außensteges 5 sind über einen Zwischensteg 12 miteinander, verschwenkbar zueinander, verbunden, der, wie Fig. 1 zeigt, am unteren Ende des Schenkels 5A etwa rechtwinklig zu diesem in Richtung auf den Profilrücken 4 hin vorspringt. In diesen Zwischensteg 12 mündet, von unten kommend und dabei unter einem spitzen Winkel vom Profilrücken 4 abspreizend, der untere Schenkel 5B mit seinem oberen Ende ein, wobei der untere Schenkel 5B gleichzeitig an seinem anderen, dem Fußbereich 3 zugewandten unteren Ende über eine Gelenkstelle in einen Dichtsteg 7 an einer Einmündestelle 9 von oben her einläuft. Der Dichtsteg 7 verläuft unter einem spitzen Winkel y, der bevorzugt im Bereich von 45° bis 50° gewählt ist, gegenüber dem Profilrücken 4, wobei er in Richtung nach oben von diesem abspreizt.The upper leg 5A and the lower leg 5B of the outer web 5 are connected via an intermediate web 12 with each other, pivotally connected to each other, which, as Fig. 1 shows at the lower end of the leg 5A protrudes approximately at right angles to this in the direction of the profile back 4 out. In this gutter 12, coming from below and while spreading at an acute angle from the profile back 4, the lower leg 5B opens at its upper end, the lower leg 5B simultaneously at its other, the foot area 3 facing the lower end via a hinge point in enters a sealing ridge 7 at a junction 9 from above. The sealing ridge 7 extends at an acute angle y, which is preferably selected in the range of 45 ° to 50 °, relative to the profile back 4, wherein it spreads in the upward direction of this.

Dabei läuft der Dichtsteg 7, in einem Abstand zum Profilrücken 4 hin versetzt, in einen Stützsteg 8 ein, der seinerseits etwa rechtwinklig in den Profilrücken 4 einmündet.In this case, the sealing web 7, offset at a distance from the profile back 4, runs into a support web 8, which in turn opens approximately at right angles into the profile back 4.

Der Dichtsteg 7 erstreckt sich außerdem über die Einmündestelle 9 des unteren Schenkels 5B des Außensteges 5 hinaus, wie Fig. 1 zeigt, wobei der überstehende Abschnitt des Dichtsteges 7 mit 7A bezeichnet ist.The sealing ridge 7 also extends beyond the mouth 9 of the lower leg 5 B of the outer web 5 addition, as Fig. 1 shows, wherein the protruding portion of the sealing ridge 7 is denoted by 7A.

Auf seiner dem Profilrücken 4 abgewandten Unterseite ist der Dichtsteg 7 im gezeigten Ausführungsbeispiel plan ausgebildet.On its side facing away from the profile back 4, the sealing web 7 is formed flat in the illustrated embodiment.

Im unbelasteten Zustand der Verglasungsdichtung 1, wie er in Fig. 1 gezeigt ist, schließen der überstehende Abschnitt 7A des Dichtsteges 7 und der untere Schenkel 5B des Außensteges 5 zwischen sich einen spitzen Winkel β ein, der vorzugsweise eine Größe im Bereich von 30° bis 35° hat.In the unloaded state of the glazing gasket 1, as in Fig. 1 is shown, the projecting portion 7A of the sealing ridge 7 and the lower leg 5B of the outer web 5 between them at an acute angle β , which preferably has a size in the range of 30 ° to 35 °.

Der obere Schenkel 5A verläuft, ebenfalls im unbelasteten Zustand der Dichtung, unter einem spitzen Winkel α , bevorzugt mit einem Wert von 20° bis 25°, schräg zum Profilrücken 4, wobei er in Richtung auf den unter ihm angeordneten unteren Schenkel 5B hin, somit von oben her, vom Profilrücken 4 abspreizend geneigt ist, wie dies die Darstellung der Fig. 1 im einzelnen zeigt.The upper leg 5A extends, also in the unloaded state of the seal, at an acute angle α , preferably with a value of 20 ° to 25 °, obliquely to the profile back 4, wherein it towards the lower leg 5B arranged below it, thus From above, is spreadingly spread from the profile back 4, as shown in the illustration of Fig. 1 in detail shows.

Der Profilrücken 4 ist an seinem dem Fußbereich 3 abgewandten oberen Ende mit einer kurzen Dichtzunge 18 versehen, die in Richtung auf die dem Hohlprofil des Kopfbereiches 2 gegenüberliegende Seite des Profilrückens 4 geneigt verläuft und im eingebauten Zustand gegen die Außenfläche eines Fensters 15 anliegt, wie dies aus den Darstellungen der Fig. 2A bis Fig. 2D sowie der Fig. 3 und 4 ersichtlich ist.The profile back 4 is provided at its upper end facing away from the foot region 3 with a short sealing tongue 18 which is inclined in the direction of the hollow profile of the head portion 2 opposite side of the profile back 4 and rests against the outer surface of a window 15 in the installed state, like this from the representations of Fig. 2A to Fig. 2D as well as the 3 and 4 is apparent.

Der Verbindungssteg 6 zwischen dem oberen Ende des oberen Schenkels 5A und dem oberen Ende des Profilrückens 4 hat im Querschnitt einen Verlauf seiner Wanddicke derart, daß die Wanddicke d in einem mittleren Bereich der Stegerstreckung verjüngt ist, während sie sich zu den beiden Enden hin vergrößert. Damit kann erreicht werden, daß in einem Einbauzustand, bei dem die abzudichtende Spaltdicke zwischen dem Fenster 15 und der abzudichtenden Gegenfläche 17a des Fensterrahmens 17 etwas geringer als die Nennspaltdicke ist, im eingebauten Zustand, wie er in Fig. 3 gezeigt ist, der Verbindungssteg 6 sich nach oben auswölben, also durch Wölbung ausweichen kann. Damit wird erreicht, daß nicht ab einem ganz bestimmten Punkt sofort ein exponentiell anwachsender Gegendruck aufgebaut wird.The connecting web 6 between the upper end of the upper leg 5A and the upper end of the profile back 4 has in cross section a course of its wall thickness such that the wall thickness d is tapered in a central region of the web extension, while it increases towards the two ends. This can be achieved that in an installed state in which the gap thickness to be sealed between the window 15 and the sealed counter surface 17a of the window frame 17 is slightly less than the nominal gap thickness, in the installed state, as in Fig. 3 is shown, the connecting web 6 bulge upwards, so can dodge by curvature. This ensures that not from a specific point immediately an exponentially increasing back pressure is built up.

Wie aus dem Querschnitt der Fig. 1 weiter entnehmbar ist, ist an der im Hohlprofil des Kopfbereiches 2 innen liegenden Seite des oberen Schenkels 5A des Außensteges 5 ein von diesem in das Innere des Kopfbereiches 2 hineinragender Auflageblock 20 angebracht, der aus einem elastischen Material, bevorzugt einem geschäumten elastischen Kunststoff, besteht und im Querschnitt angenähert die Form eines Rechteckes aufweist. Er liegt an seiner unteren Abschlußseite gegen die Innenfläche des Zwischensteges 12 an, die er aber in Richtung auf den Hohlquerschnitt des Kopfbereiches 2 überragt.As seen from the cross section of Fig. 1 is further removed, is mounted on the inside of the hollow portion of the head portion 2 side of the upper leg 5A of the outer web 5 a protruding from this in the interior of the head portion 2 support block 20, which consists of an elastic material, preferably a foamed elastic plastic, and Has approximately the shape of a rectangle in cross section. He lies at its lower end side against the inner surface of the intermediate web 12, but it projects beyond in the direction of the hollow cross section of the head portion 2.

Auf dem Niveau dieses Auflageblockes 20 ist an der Rückseite des Profilrückens 4 ein Klebestreifen 19 dauerhaft untrennbar angebracht, der mit dem Profilrücken 4 z. B. geeignet verschweißt sein kann. Dieser Klebestreifen 19 dient dazu, beim Einbau der Verglasungsdichtung 1 deren Profilrücken 4 an der entsprechenden Stelle rückseitig an der vorderen Endfläche eines hier abzudichtenden Fensters 15 zu befestigen. Diese Verklebung am Fenster 15 sorgt ebenfalls dafür, daß überhaupt keine Feuchtigkeit oder keine Verschmutzung an der Außenseite der Fensterscheibe zwischen diese und den Profilrücken 4 gelangen kann.At the level of this support block 20, an adhesive strip 19 is permanently inseparably attached to the back of the profile back 4, which with the profile back 4 z. B. may be suitably welded. This adhesive strip 19 serves to secure the profile back 4 at the corresponding location at the front end surface of a window 15 to be sealed here when installing the glazing gasket 1. This adhesion to the window 15 also ensures that no moisture or dirt on the outside of the window can get between them and the profile back 4 at all.

Der Auflageblock 20 ist dabei so am oberen Schenkel 5A angeordnet, daß er in einem voll eingeklappten Zustand, also bei Kontakt zwischen seiner innen liegenden Endfläche und der zugewandten Fläche des Profilrückens 4, ziemlich genau am Profilrücken 4 der Anordnung des Klebestreifens 19 gegenüberliegt. Damit kann bei der Montage durch ein Eindrücken des Schenkels 5A und Andrücken des Auflageblockes 20 gegen den Profilrücken 4 eine entsprechende Kraft auf den Profilrücken 4 und von diesem auf den Klebestreifen 19 aufgebracht und dadurch das Ankleben des Dichtrückens 4 an der Außenfläche des Fensters 15 beim Einbau realisiert werden.The support block 20 is arranged on the upper leg 5A so that it is in a fully folded state, so in contact between its inner end surface and the facing surface of the profile back 4, pretty much opposite to the profile back 4 of the arrangement of the adhesive strip 19. This can during assembly by pressing the leg 5A and pressing the support block 20 against the profile back 4 a corresponding force applied to the profile back 4 and from this on the adhesive strip 19 and thereby the adhesion of the sealing back 4 are realized on the outer surface of the window 15 during installation.

Als Material für den Auflageblock 20 kann z. B. vorzugsweise ein geeignetes geschäumtes TPE mit 20° bis 25° ShA eingesetzt werden, während für das andere Material des Kopfbereiches 2 z. B. eine Härte von 60° ShA vorgesehen werden kann.As a material for the support block 20 z. B. preferably a suitable foamed TPE with 20 ° to 25 ° ShA be used, while for the other material of the head region 2 z. B. a hardness of 60 ° ShA can be provided.

Grundsätzlich ist anzumerken, daß der Auflageblock 20 statt an der Rückseite des oberen Schenkels 5A aber auch am Profilrücken 4 des Kopfbereiches 2 befestigt sein könnte, und zwar dort der Lage des Klebestreifens 19 gegenüberliegend, so daß in diesem Fall bei der Montage der Dichtung der obere Schenkel 5A frei eingeschwenkt und erst nach Anlage an der ihm zugewandten Seite des Auflageblockes 2 die für das Andrücken des Klebestreifens 19 an das Fenster 15 erforderliche Andruckkraft aufgebracht werden kann.Basically, it should be noted that the support block 20 could be attached instead of at the back of the upper leg 5A but also the profile back 4 of the head portion 2, there the position of the adhesive strip 19 opposite, so that in this case when mounting the seal of the upper Leg 5A pivoted freely and only after contact with the side facing him the support block 2 for pressing the adhesive strip 19 to the window 15 required pressure force can be applied.

In den Figuren 2A, 2B, 2C und 2D ist die Verglasungsdichtung aus Fig. 1 anhand eines Beispiels im eingebauten Zustand dargestellt, wobei die vier Figuren 2A bis 2D einen Schließvorgang eines Fensters 15 in einem Rahmen 17 darstellen, und zwar in unterschiedlichen Schließstellungen: Darin zeigt Fig. 2A den Augenblick, in welchem die Verglasungsdichtung 1 mit ihrem frei vorstehenden Dichtsteg 7 beim Einschwenken gerade in Kontakt mit der abzudichtenden Gegenfläche 17a des Rahmens 17 gelangt. In diesem Zustand ist der Kopfbereich 2 der Verglasungsdichtung 1 noch nicht deformiert, wie das aus Fig. 2A ersichtlich ist.In the FIGS. 2A, 2B, 2C and 2D is the glazing gasket off Fig. 1 illustrated by an example in the installed state, the four FIGS. 2A to 2D illustrate a closing operation of a window 15 in a frame 17, in different closed positions: Darin shows Fig. 2A the moment in which the glazing gasket 1 with its freely projecting sealing web 7 when swiveling just in contact with the sealed counter surface 17a of the frame 17 passes. In this state, the head portion 2 of the glazing gasket 1 is not yet deformed, like that Fig. 2A is apparent.

Fig. 2B zeigt einen etwas späteren Schließzustand, bei dem das Fenster 15 eine Schließstellung erreicht hat, in der der Dichtsteg 7 von der abzudichtenden Gegenfläche 17a so weit in Richtung auf den zweiten Schenkel 5B verschwenkt ist, daß er an dessen Außenfläche gerade noch nicht (oder vielleicht auch gerade schon) anliegt. Außer der Verschwenkung des Dichtsteges 7 hat jedoch noch keine oder fast keine Deformation des Kopfbereiches 2 der Verglasungsdichtung 1 stattgefunden. Fig. 2B shows a slightly later closed state, in which the window 15 has reached a closed position in which the sealing ridge 7 is pivoted so far from the sealed counter surface 17a in the direction of the second leg 5B, that he just on its outer surface not (or maybe already). However, apart from the pivoting of the sealing web 7, no or almost no deformation of the head region 2 of the glazing gasket 1 has taken place.

Fig. 2C illustriert einen wieder etwas späteren Schließzustand, bei dem durch eine weitere Annäherung des einschwenkenden Fensterflügels 16 mit dem Fenster 15 in Richtung auf den Fensterrahmen 17 hin der Dichtungssteg 7 mit dem an ihm anliegenden unteren Schenkel 5B und gleichzeitig auch der obere Schenkel 5A in Richtung auf den Profilrücken 4 hin noch weiter eingedrückt sind. Hier ist erkennbar, daß der Dichtsteg 7 mit seiner dem Fensterrahmen 17 zugewandten Außenseite schon über so gut wie seine ganze über den Einmündesteg des unteren Schenkels 5B hinausragende Länge 7A an der abzudichtenden Gegenfläche 17a anliegt. Fig. 2C illustrates a somewhat later closing state, in which by a further approximation of the pivoting window sash 16 with the window 15 in the direction of the window frame 17 toward the sealing web 7 with the voltage applied to it lower leg 5 B and at the same time the upper leg 5 A in the direction of the Profile back 4 are pushed even further. Here it can be seen that the sealing ridge 7 with its the window frame 17 facing outside already about as good as its whole on the Einmündesteg of the lower leg 5B projecting length 7A rests against the counter-surface 17a to be sealed.

Fig. 2D zeigt schließlich den Schließ-Endzustand, wobei hier für die Größe des abzudichtenden Spaltes dessen Nennweite, im gezeigten Ausführungsbeispiel z. B. 5,5 mm, angenommen ist. Fig. 2D shows finally the closing end state, in which case for the size of the gap to be sealed whose nominal diameter, in the embodiment shown z. B. 5.5 mm, is assumed.

In diesem Zustand liegt der Dichtsteg 7 an seiner gesamten Außenfläche an der abzudichtenden Gegenfläche 17a des Fensterrahmens 17 an, desgleichen hat sich aber auch der obere Schenkel 5A des Außensteges 5 ebenfalls an seiner ganzen Außenfläche gegen die abzudichtende Gegenfläche 17a angelegt. Hieraus ist ersichtlich, daß über eine sehr große Kontaktfläche, die von der Oberseite des Fensterrahmens 17 bis hin zur Unterseite des Kopfbereiches 2 der Verglasungsdichtung 1 reicht, eine Dichtanlage gewährleistet ist.In this state, the sealing ridge 7 rests on its entire outer surface on the sealed counter surface 17a of the window frame 17, but also the upper leg 5A of the outer web 5 has also applied to its entire outer surface against the counter-surface 17a to be sealed. It can be seen that over a very large contact surface, which extends from the top of the window frame 17 to the bottom of the head portion 2 of the glazing gasket 1, a sealing system is ensured.

Aus Fig. 2D kann aber auch entnommen werden, daß zwischen der nach innen ragenden Endfläche des am oberen Schenkel 5A befestigten Auflageblocks 20 und der ihm zugewandten Innenfläche des Profilrückens 4 ein noch sehr kleiner Restspalt (von z. B. 0,3 mm bis 0,5 mm) vorhanden ist.Out Fig. 2D but it can also be seen that between the inwardly projecting end surface of the support member 20 attached to the upper leg 5A and the inner surface of the profile back 4 facing it, a still very small residual gap (of, for example, 0.3 mm to 0.5 mm) is available.

In den Fig. 3 und 4 sind noch einmal zwei Einbauzustände für die erfindungsgemäße Verglasungsdichtung 1 gezeigt, wobei Fig. 3 den Schließ-Endzustand bei einer Spaltweite mit Untermaß (etwa 5,0 mm) und Fig. 4 den Schließ-Endzustand bei einer Spaltweite mit Übermaß (etwa 7 mm) zeigt.In the 3 and 4 Once again two installation states for the glazing gasket 1 according to the invention are shown, wherein Fig. 3 the closing final state at a gap width with undersize (about 5.0 mm) and Fig. 4 shows the closing final state with a gap width with oversize (about 7 mm).

Hier ist bei der Darstellung nach Fig. 3 der obere Verbindungssteg 6 leicht nach oben ausgewölbt und der Auflageblock 20 liegt rückseitig gegen den Profilrücken 4 an.Here is the presentation after Fig. 3 the upper connecting web 6 bulged slightly upwards and the support block 20 is against the back of the profile 4 at the back.

Der obere Schenkel 5A des Außensteges 5 und der Dichtsteg 7 liegen ebenfalls mit ihren Außenseiten gegen die abzudichtende Gegenfläche 17a in voller Länge an, so daß eine sehr große Abdichtfläche gegeben ist.The upper leg 5A of the outer web 5 and the sealing web 7 are also with their outer sides against the sealed counter surface 17a in full length, so that a very large sealing surface is given.

Bei der Einbausituation, wie sie aus Fig. 4 entnehmbar ist, ist die Verglasungsdichtung 1 in einen Dichtspalt eingebaut, der deutlich größer als der Nenn-Dichtspalt ist, im gezeigten Beispiel z. B. eine Weite von 7 mm hat.In the installation situation, how they look Fig. 4 can be removed, the glazing gasket 1 is installed in a sealing gap which is significantly larger than the nominal sealing gap, in the example shown z. B. has a width of 7 mm.

Bei dieser Einbausituation ist der obere Verbindungssteg 6 nicht ausgewölbt, sondern er ragt vom Fenster 15 nicht ganz bis zum zugewandten Ende des Fensterrahmens 17. Vom Ende des Verbindungssteges 6 läuft der obere Schenkel 5A des Außensteges 5 zunächst etwas geneigt bis hin zu der abzudichtenden Gegenfläche 17a, an der er dann anliegt und parallel zu ihr in Richtung auf den Dichtsteg 9 verläuft, der seinerseits über seine ganze Länge darunter an der abzudichtenden Gegenfläche 17a anliegt. Hier besteht zwar die Möglichkeit, daß oben über den kleinen Keilspalt, der zwischen dem oberen Bereich des oberen Schenkels 5A und der abzudichtenden Gegenfläche 17a verläuft, von außen her Flüssigkeit eindringen kann. Diese wird dann aber an der Stelle, an welcher der obere Schenkel 5A gegen die abzudichtende Gegenfläche 17a anliegt und angedrückt ist, von einem weiteren Eindringen in den Spalt abgehalten. Sollte doch noch ein Eindringen stattfinden, wird die entsprechende Flüssigkeit in den Bereich zwischen der Dichtlippe 7 und der dieser zugewandten Außenfläche des unteren Schenkels 5B eingeleitet und dort aufgenommen, so daß es nicht zu einem noch weiteren Eindringen von Flüssigkeit kommen kann.In this installation situation, the upper connecting web 6 is not bulged, but he does not quite project from the window 15 to the facing end of the window frame 17. From the end of the connecting web 6 of the upper leg 5A of the outer web 5 initially runs slightly inclined to the sealed counter surface 17a where he then rests and parallel to her in Direction to the sealing ridge 9 runs, which in turn rests over its entire length underneath against the counter-surface 17 a to be sealed. In this case, there is the possibility that liquid may penetrate from the outside via the small wedge gap which runs between the upper region of the upper leg 5A and the counter-surface 17a to be sealed. However, this is then held at the point at which the upper leg 5A bears against the counter-surface 17a to be sealed and is pressed, from further penetration into the gap. Should still take place penetration, the corresponding liquid is introduced into the region between the sealing lip 7 and the outer surface facing the lower leg 5B and received there, so that it can not come to an even further penetration of liquid.

Die in den Figuren gezeigte Ausgestaltung des Fußbereiches 3 der Verglasungsdichtung 1 und dessen Halterippe 13 zeigt nur eine beispielsweise Ausgestaltung. Selbstverständlich kann der Fußbereich 3 auch in anderer Form ausgestaltet sein, desgleichen die Halterippe 13, etwa in Form eines oder mehrerer schräg nach oben an einem Dichtungsfuß übereinander angeordneter Halterippen, die in eine Aufnahmenut eingreifen, welche nicht, wie in den gezeigten Ausführungsbeispielen, waagrecht, sondern senkrecht, also in Längsrichtung des Profilrückens 4, angebracht ist.The embodiment of the foot region 3 of the glazing gasket 1 and its retaining rib 13 shown in the figures shows only one example embodiment. Of course, the foot portion 3 may be configured in another form, as well as the retaining rib 13, approximately in the form of one or more obliquely upwardly on a sealing foot arranged holding ribs which engage in a receiving groove, which not, as in the embodiments shown, horizontal, but perpendicular, ie in the longitudinal direction of the profile back 4, is attached.
