Description

Lochabdeckende DärnpfungsfolieHole-covering damping film
Die vorliegende Erfindung betrifft eine lochabdeckende Dämpfungsfolie für Fahrzeugböden gemäss Oberbegriff des Anspruchs 1.The present invention relates to a hole-covering damping film for vehicle floors according to the preamble of claim 1.
Die Bodenbleche von Fahrzeugen sind in vielfältiger Weise geformt, um eine Vielzahl mechanischer Erfordernisse zu erfüllen. Insbesondere weisen diese Bodenbleche versteifende Sicken oder Ausnehmungen auf, welche, unter anderem, der Befestigung vcn weiteren Fahrzeugteilen dienen. Lochsicken weisen m der Regel ein Loch auf, durch welches ein Befestigungsmittel , insbesondere eine Schraube, hindurchgeführt werden kann. Darüber hinaus werden aus ökonomischen Gründen die Fahrzeugbodenbleche derart gestaltet, dass diese für verschiedene Fahrzeugtypen verwendet werden können. Es versteht sich deshalb, dass im montierten Zustand nicht alle im Bodenblech eingebrachten Öffnungen respektive Löcher für ihren vorgesehenen Zweck verwendet werden. Es ergibt sich deshalb die Notwendigkeit, diese Öffnungen nachträglich wieder abzudichten.Vehicle floor panels are shaped in a variety of ways to meet a variety of mechanical requirements. In particular, these floor panels have stiffening beads or recesses which, among other things, serve to fasten other vehicle parts. Hole beads generally have a hole through which a fastening means, in particular a screw, can be passed. In addition, for economic reasons, the vehicle floor panels are designed in such a way that they can be used for different types of vehicles. It is therefore understood that not all openings or holes made in the floor panel are used for their intended purpose in the assembled state. There is therefore a need to subsequently seal these openings again.
Elemente zum Abdichten von ungenutzten Löchern in derartigen Bodenblechen sind dem Fachmann hinlänglich bekannt und können in Form von Verschluss -Stopfen aus Kunststoff und/oder Gummi ausgebildet sein. Diese Verschluss-Stopfen beispielsweise werden mit Hilfe von Klebern wasserdicht am Bodenblech befestigt.Elements for sealing unused holes in such floor panels are well known to the person skilled in the art and can be designed in the form of sealing plugs made of plastic and / or rubber. These plugs, for example, are attached to the floor panel in a watertight manner using adhesives.
Es sind auch folienartige Abdeckungen bekannt, welche über die Löcher geklebt werden. Diese Folien neigen dazu, im Lochbereich stark durchzuhängen. Es sind deshalb auch Folien bekannt:, die vollflächig mit einer versteifenden Schicht, z.B. aus Karton, Papier oder Aluminium abgedecktFoil-like covers are also known, which are glued over the holes. These foils tend to sag heavily in the hole area. Films are therefore also known: which cover the entire surface with a stiffening layer, e.g. covered from cardboard, paper or aluminum
BFS1ÄTIGLJNCSK0PIF sind. Diese versteiften Folien lassen sich jedoch im Bereich von Sicken, insbesondere Lochsicken, nur schlecht am Bodenblech befestigen, insbesondere verkleben.BFS1ÄTIGLJNCSK0PIF are. These stiffened foils, however, are difficult to attach, in particular glue, to the floor panel in the area of beads, in particular perforated beads.
Das Anbringen dieser Lochabdeckungen erfordert einen separaten Fertigungsschritt. Insbesondere müssen ausgewählte Verschluss-Stopfen in die jeweils unterschiedlich geformten Bodenblechöffnungen eingesetzt werden oder müssen verschieden dimensionierte Folienstücke korrekt auf den Öffnungen positioniert werden, was sich als zeit- und arbeitsintensiv erweist.Attaching these hole covers requires a separate manufacturing step. In particular, selected sealing plugs must be inserted into the differently shaped floor panel openings or differently sized pieces of film must be correctly positioned on the openings, which proves to be time-consuming and labor-intensive.
Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Lochabdeckung zu schaffen, die m einfacher Weise montiert respektive eingesetzt werden kann und die Nachteile der bekannten Lochabdeckungen nicht aufweist. Insbesondere soll eine Lochabdeckung geschaffen werden, die sich für die Verwendung bei Lochsicken eignet und im Lochbereich bei grösseren Öffnungen nicht wesentlich durchhängt.It is therefore an object of the present invention to provide a perforated cover which can be assembled or used in a simple manner and does not have the disadvantages of the known perforated covers. In particular, a hole cover is to be created which is suitable for use with hole beads and which does not sag significantly in the hole area in the case of larger openings.
Diese Aufgabe wird er mdungsgemass mit einer Dampfungsfolie mit den Merkmalen des Anspruchs 1 gelöst, und insbesondere mit einer Dämpfungsfolie, welche m vorbestimmten Bereichen partiell nit einer Verstärkungsschicht versehen ist. In einer ersten Anwendung liegen die vorbestimmten Bereiche über einem Loch des Bodenblechs und insbesondere über einer Lochsicke. Dies führt dazu, dass die relativ weicne Dampfungsfolie von der Verstarkungsschicht daran gehindert wird, durch das Loch durchzuhangen , was auf der Fahrzeuginnenseite zu einer unerwünschten Vertiefung führen wurde . Es versteht sich, dass diese Verstarkungsschicht auf jeder oder auf beiden Seiten der Dämpfungsfolie angebracht sein kann. In einer anderen Anwendung liegt der zu verstärkender Bereich über einem Schwingungsbereich des Bodenblechs. Es ist dem Fachmann bekannt, dass sich bei Vibrationen resp. Schwincungen von grösseren flächigen Bauteilen verschiedene Schwingungsbereiche ausbilden zwischen denen sogenannte Knotenlinien verlaufen. Im Bereich der Knotenlinien vibrieren diese flächigen Bauteile nur minimal, während diese Bauteile m den Schwingungsbereichen unerwünschte Schwingungsbauche erzeugen. Es sind diese Schwingungsbereiche, die mit der vorliegenden Erfindung zusätzlich gedampft werden können, ohne die Masse der Dampfungsfolie m diesen Bereichen nennenswert erhöhen zu müssen.This object is achieved in accordance with the invention with a damping film having the features of claim 1, and in particular with a damping film which is partially provided with a reinforcing layer in predetermined areas. In a first application, the predetermined areas lie over a hole in the floor panel and in particular over a hole bead. This leads to the relatively white damping film being prevented from sagging through the hole by the reinforcing layer, which would lead to an undesired depression on the inside of the vehicle. It goes without saying that this reinforcing layer can be applied on either or on both sides of the damping film. In another application, the area to be reinforced lies above a vibration area of the floor panel. It is known to the person skilled in the art that vibrations or. Vibrations of larger flat components form different vibration areas between which so-called node lines run. In the area of the node lines, these flat components vibrate only minimally, while these components generate undesired antinodes in the vibration areas. It is these vibration areas that can be additionally dampened with the present invention without having to increase the mass of the damping film significantly in these areas.
Mit der vorliegenden Erfindung wird also nicht nur der aufwendige Arbeitsgarg zum Abdecken der Locher vereinfacht resp. kann auf diesen Arbeitsgang verzichtet werden, sondern kann gleichzeitig das Dampf ngsverhalten der Dampfungsfolie in gewünschter Weise lokal beemflusst respektive kontrolliert werden.With the present invention, not only is the complex work yard for covering the holes simplified or simplified. this step can be dispensed with, but at the same time the steaming behavior of the steaming film can be locally influenced or controlled in the desired manner.
Im folgenden soll die Erfindung anhand der Figuren und eines Ausf hrungsbeispiels naher erläutert werden.The invention will be explained in more detail below with reference to the figures and an exemplary embodiment.

Fig .1 zeigt ein Bodenblech 1 m welches eine Lochsicke 2 eingeformt ist und welche Lochsicke ein zentrales Loch 3 aufweist. Über diesem Bodenblech ist eine er indungsgemässe Dämpfungsfolie 4 angebracht. Diese Dämpfungsfolie ist mindestens im Bereich β der Lochsicke 2 mit einer zusätzlichen Verstarkungsschicht 5 versehen. Diese Verstarkungsschicht 5 kann aus Papier, Karten, Kunststoff, Filz, Aluminium, usw. bestehen und kann voll flächig oder gitterförmig ausgebildet sein. Diese Verstärkungsschicht kann aufkaschiert , kalandriert und/oder aufgeklebt werden. Damit wird erreicht, dass sich die vollflächig ausgelegte Dämpfungsfolie 4 dem Sickenverlauf ungehindert anschmiegen kann und damit ihre schalldämpfende Funktion noch besser erfüllen kann. Andererseits wird durch die1 shows a base plate 1 m which has a hole bead 2 formed in it and which hole bead a central hole 3 having. A damping film 4 according to the invention is attached to this floor panel. This damping film is provided with an additional reinforcing layer 5 at least in the area β of the bead 2. This reinforcing layer 5 can consist of paper, cards, plastic, felt, aluminum, etc. and can be designed to be completely flat or lattice-shaped. This reinforcement layer can be laminated on, calendered and / or glued on. It is thereby achieved that the full-area damping film 4 can nestle unhindered along the course of the beads and thus can perform its sound-absorbing function even better. On the other hand, the
Verstärkungsschicht 5 verhindert, dass die Dampfungsfolie 4 im Lochbereich 3 durchhäng . Darüber hinaus kann mit dem gezielten Aufbringen von weiteren partiellenReinforcement layer 5 prevents the damping film 4 from sagging in the hole area 3. In addition, with the targeted application of further partial

Insbesondere können Bereiche 6a, in denen sich m voraussehbarer Weise Schwingungsbäuche ausbilden, im folgenden Schvmgungsbereiche genannt, gezielt gedämpft werden . Die erf indungsgemässe Dämpfungsfolie 4 erfüllt damit mehrere Funktionen gleichzeitig .Reinforcement layers 5a influence and control the damping behavior of the damping film 4 in the desired manner. In particular, areas 6a in which vibration antinodes are to be formed in a predictable manner, hereinafter referred to as vibration areas, can be specifically damped. The damping film 4 according to the invention thus fulfills several functions simultaneously.
Fig. 2 zeigt eine weitere Ausführungsform der erfindungsgemässen Dämpfungsfolie 4 im montierten Zustand. Diese Dampfungsfolie 4 ist wiederum vollflächig auf einem Bodenblech 1 aufgebracht und schmiegt sich den Konturen desselben an, insbesondere im Bereich stärkerer Verformungen, beispielsweise einer Lochsicke 2.2 shows a further embodiment of the damping film 4 according to the invention in the assembled state. This damping film 4 is in turn applied to the entire surface of a floor panel 1 and conforms to the contours thereof, in particular in the area of severe deformations, for example a bead 2.
Erfindungsgemäss ist diese Dämpfungsfolie 4 im Bereich 6 der Lochsicke 2 mit einer Verstärkungsschicht 5 versehen, welche verhindert, dass die weiche Dämpfungsfolie 4 durch die Öffnung 3 durchhängt. Darüber hinaus schützt diese Verstarkungsschicht 5 die Dampfungsfolie 4 vor mechanischen Verletzungen im Lochbereich. Geeignete Dampfungsfolien sind dem Fachmann hinlänglich bekannt. Insbesondere bietet es sich an, eine unter dem Namen „IFF" bekannte Dampfungsfolie zu verv,enden. Es versteht sich, dass die partiellen Verstarkungsscmchten 5, 5a auf beiden Seiten der Dampfungsfolie 4 angebracht werden können und der Fachmann in Abhängigkeit der zu erfüllenden Funktion diese Verstarkungsscmchten in geeigneter Weise anordnen und dimensionieren ,/ιrd.According to the invention, this damping film 4 is provided in the region 6 of the bead 2 with a reinforcing layer 5, which prevents the soft damping film 4 from sagging through the opening 3. It also protects Reinforcement layer 5 the damping film 4 against mechanical injuries in the hole area. Suitable damping foils are well known to the person skilled in the art. In particular, it makes sense to use a damping film known under the name "IFF". It goes without saying that the partial reinforcement layers 5, 5a can be attached to both sides of the damping film 4 and the person skilled in the art can do so depending on the function to be performed Arrange and dimension reinforcement in a suitable manner, / ιrd.
Die Vorteile αer erfmdungsgemässen Dampfungsfolie sind dem Fachmann unmittelbar ersichtlich Insbesondere kann das aufwendige Abdichten der Offnungen des Bodenbleches durch das einfache und vollflachige Aufbringen der erfmdungsgem ssen Dampfungsfolie ersetzt werden. Darüber hinaus erlaubt die erfindungsgemässe Dampfungsfolie dem Fachmann, das Dampfungsverhalten der Dampfungsfolie gezielter Weise zu beeinflussen und ermöglicht die bloss partielle Anordrung der Verstarkungsschichten 5, 5a eine gute, insbesondere wasserundurchlässige Abdichtung der Fahrzeugbodenlccher durch die Dampfungsfolie , ohne dass diese im Bereich dei Locher 3 durchhangt. Es versteht sich, dass diese Verstarkungsschichten 5, 5a auch Bereichen angeordnet wercen können, in welchen ein erhöhte mechanische Beanspruchung der Dampfungsfolie zu erwarten ist . The advantages of the damping foil according to the invention are immediately apparent to the person skilled in the art. In particular, the complex sealing of the openings in the floor panel can be replaced by the simple and full-surface application of the damping foil according to the invention. In addition, the damping film according to the invention allows the person skilled in the art to influence the damping behavior of the damping film in a targeted manner and the mere partial arrangement of the reinforcing layers 5, 5a allows the vehicle floor gaps to be sealed well, in particular water-impermeably, by the damping film without sagging in the area of the perforation 3. It goes without saying that these reinforcing layers 5, 5a can also be arranged in areas in which increased mechanical stress on the damping film can be expected.
