Abstract

The windscreen sealing strip for a vehicle has grooves (6) incorporated in the profile to act as damping layers for the edge of the glass (1). The damping layers depress any low frequency vibrations inside the vehicle and provide a quieter ride. No external damping is required for the glass and the glass fitting process is not changed. The layers are arranged around the edge of the glass groove, and can reach into the groove if required.

Description

"Profil zur Halterung fest eingebauter Scheiben""Profile for holding permanently installed panes"

Die Erfindung betrifft ein aus elastischem Naterial bestehemdes Profil zur Halterung fest eingebauter Scheiben, insbesondere von Front- oder Heckscheiben von Kraftwagen, mit einer umlaufenden Nut zur Aufnahme der Scheibenkante.The invention relates to a profile made of elastic material for holding permanently installed windows, especially front or rear windows of motor vehicles, with a circumferential groove to accommodate the window edge.

Mechanische und akustische Schwingungen am Kraftfahrzeug führen in den meisten Fällen zu schwingungen der Luft im Fatirgasraum. Die Einleitung der durch das Antriebsaggregat und das Fahrwerk erzeugten Schwingungen erfolgt iiber den Doden, das Dach, die Seitenwinde usw.. Handelt es sich um niederfrequente Schwingungen so werden diese noch durch die Geometrie des Fahrgastraumes begünstigt, d.h. Raumeigenfrequenzen werden angeregt und führen so zu akustischen Resonanzen mit hohem Schalldruck. Die aus akustischer Sicht nahezu steifen Paumbegrenzungen verhindern die Absorption der so entstehenden Schwingungen der Luft im Fahrgastraum. Durch Reflexion entstehen sogenannte stehende Wellen.Mechanical and acoustic vibrations on the motor vehicle lead to in most cases to vibrations of the air in the Fatirgasraum. The initiation of the The vibrations generated by the drive unit and the chassis take place via the dodes, the roof, the cross winds, etc. Is it a matter of low-frequency vibrations? so these are favored by the geometry of the passenger compartment, i.e. natural frequencies of the room are excited and thus lead to acoustic resonances with high sound pressure. the From the acoustic point of view, the paws are almost rigid and prevent absorption the resulting vibrations in the air in the passenger compartment. Arise through reflection so-called standing waves.

Sofern die Schwingungsanregung nicht beseitigt werden kann, behilft man sich z.n. mit Hohlraumresonatoren oder mit Absorptionsbelägen an den Wänden.If the vibration excitation cannot be eliminated, help one z.n. with cavity resonators or with absorption coverings on the walls.

Beide Maßnahmen sind, insbasondere bei tiefen Frequenzen, @@ Hraitfahrzeug oft unealistisch oder wirkungslos wegen des darär erforderlichen Flatzbedarfs bzw. wegen Fichtberächsich-@igang der den Fahrgastraum zum großen Teil amschließendes Scheiben.Both measures are, especially in the case of low frequencies, @@ Hraitfahrzeug Often unrealistic or ineffective because of the space required or Because of the Fichtberächsich- @ igang of the passenger compartment for the most part at the closing Discs.

@er @gfindung liegt din @ufgabe zugrande, mit einfachen Fitteln die fest eingeb@uten Scheiben des Fahrgastraunes in den Dämpfungsmechanismus der @aumbegrenzung mit einzubeziehen.@er @gfindung is the @ task zugrande, with simple tools that windows of the passenger compartment firmly embedded in the damping mechanism of the room delimitation to be included.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß beiderseitss der Nut in sich geschlossene @chlhammsern vorgesehen sind, deren der Nut augekehrte Vandteile bei montierter Scheibe als schall- und schwingungsdämpfende Membran wirken.This object is achieved according to the invention in that both sides the groove self-contained @chlhammsern are provided, which the groove obeyed Vand parts act as a sound and vibration dampening membrane when the disc is installed.

Aus der DE-A@ 21 19 617 ist zwar bereits eine Profilleiste zur Halterung von fest eingebauten Scheiben bekannt, die zur Montageerleichterung auf einer Seite einer der Aufnahme des Scheibenrandes dienenden umlaufenden Zut einen Rohlraum aufweist. Eine Varbesserung der Schwingungsdämpfung der fest eingebauten Scheiben ist dabei jedoch weder beabsichtigt noch erreichbar.From DE-A @ 21 19 617 there is already a profile strip for mounting of permanently installed panes known to facilitate assembly on one side one of the circumferential allotment serving to hold the edge of the pane has a hollow space. There is also an improvement in the vibration damping of the permanently installed panes however, neither intended nor achievable.

Vorteilhafte Ausführungsformen derd Erfindung sind den weiteren P a t e n t a n s p r ü c h e n zu entnehmen.Advantageous embodiments of the invention are the further P. a t e n t a n s p r u c h e n can be found.

Der Gegenstand der Erfindung soll im folgenden anhand von zwei in der Zeichnung jeweils im Schnitt dargestellten Ausführungsbeispielen näher erläutert werden.The subject matter of the invention will hereinafter be based on two in the drawing explained in more detail embodiments shown in section will.

Mit 1 ist dabei jeweils die Scheibe, mit 2 das Profil, mit 3 der Scheibenrahmen und mit 11 ein mit deni Rahmen 3 fest verbundener Steg bezeichnet. Die den Stand der Scheibe 1 aufnehmende Nut 5 ist erfindungsgemäß von als Luftpolster wirkenden, in sich geschlossenen llolllkammern 6 umgeben.1 is the window, 2 is the profile, 3 is the window frame and 11 denotes a web fixedly connected to the frame 3. The stand the disc 1 receiving groove 5 is according to the invention of acting as an air cushion, enclosed llolllkammern 6 in itself.

Das Cigens chwingverlialt en wird in Abhängigkeit von der Größe und Dicke der Scheibe 1 durch entsprechende Dimensionierung der lIohlkammern 6 sowie deren als Membran wirkenden Wandungen 7 abgestimmt. Die Dämpfung dieser Schwingungsgebilde kann durch die Härte des aus einem Elastomer bestehenden Profils 2 beeinflußt werden.The cigens is chwingverlialt depending on the size and Thickness of the disk 1 by appropriate dimensioning of the hollow chambers 6 as well whose walls 7 acting as a membrane are matched. The damping of these oscillations can be influenced by the hardness of the profile 2 made of an elastomer.
