Bei solchen bekannten Bauteilen (deutsches Gebrauchsmuster 6 805 255) dient die Schicht aus Kunststoff dazu, dem Bodenbelag eine gewisse Formsteifigkeit zu verleihen, wenn dieser zur Anpas-Bung an Unebenheiten des Fahrzeugbodens verformt werden muß. Um zu verhindern, daß die noch vorgesehene, offen an der LInterseite des Bodenbelages angebrachte Filzschicht sich mit Wasser vollsaugt, das in das Wageninnere z. B. in Form von Schnee eingebracht wird, und um den Zusammenhalt aller Einzelteile zu sichern, ist die Filzunterlage an ihrer Unterseite durch eine Folie aus thermoplastischem Kunststoff abgedeckt, die an den Rändern des Bodenbelages mit der aus thermoplastischem Kunststoff bestehenden Unterseite der textlien Oberschicht verschweißt ist. Die Aufgabe dieses Bauteiles besteht also darin, daß ein Vollsaugen der Filzschicht mit Wasser verhindert wird. Die Schalldämmung ist verhältnismäßig gering.In such known components (German utility model 6 805 255) the layer is used Plastic is used to give the flooring a certain degree of stiffness when it is used for adaptation must be deformed on unevenness in the vehicle floor. To prevent the planned, The felt layer, which is openly attached to the inside of the floor covering, soaks up water, which in the car interior z. B. is introduced in the form of snow, and the cohesion of all items To secure the felt pad on its underside with a film made of thermoplastic material covered the edges of the flooring with the thermoplastic material The underside of the textile top layer is welded. The task of this component exists that is, the fact that the felt layer is prevented from being soaked with water. The sound insulation is proportionate small amount.
Es ist auch bekannt, derartige Vorsatzschalen als Resonanzabsorber (Glasers Annalen, Nr. 12, S. 449, rechte Spalte, vorletzter Absatz und S. 448, Bild 3) aus einer Schwerschicht auf einer elastischen Zwischenschicht vor starrer Trennwand herzustellen. Ein solcher Resonanzabsorber besteht aus sechs zu beiden Seiten eines Stahlbleches angeordneten Schichten und ist damit verhältnismäßig aufwendig und teuer. Weiter erfordert ein solcher bekannter Resonanzabsorber zusätzliche Teile zu seiner Befestigung.It is also known to use such facing shells as resonance absorbers (Glaser's Annalen, No. 12, p. 449, right column, penultimate paragraph and p. 448, Fig. 3) from a heavy layer on an elastic intermediate layer in front of a rigid partition. Such a resonance absorber consists of six to both Sides of a steel sheet arranged layers and is therefore relatively expensive and expensive. Furthermore, such a known resonance absorber requires additional parts for its attachment.
Aufgabe der Erfindung ist es, ein mehrschichtiges schalldämmendes Bauteil gemäß der eingangs genannten Gattung so auszubilden, daß mit einfachen Mitteln eine gute Schalldämmung und eine einfache und sichere Montage erzielt wird.The object of the invention is to provide a multilayer sound-absorbing component in accordance with the aforementioned To train genus so that with simple means a good sound insulation and a simple and secure assembly is achieved.
Die erfindungsgemäße Lösung besteht darin, daß die Kunststoffschicht — wie bekannt — als Schwerschicht ausgebildet ist und mit der textlien Oberschicht eine vorgeformte Schale bildet, die schwimmend auf der Schicht aus biegeweichem Werkstoff von mindestens 10 mm Dicke angeordnet ist.The solution according to the invention consists in that the plastic layer - as is known - as a heavy layer is formed and forms a preformed shell with the textile top layer, which is floating is arranged on the layer of flexible material with a thickness of at least 10 mm.
So gelingt es, das Bauteil ohne besondere Befestigungsvorrichtungen örtlich festzulegen und auf der Schicht aus biegeweichem Werkstoff schwimmen zu lassen. Diese Schicht hat eine erhebliche Dicke und kann so auch im Zusammenwirken mit der starken, tragenden Schwerschicht Fertigungstoleranzen ausgleichen. This is how the component succeeds without special fastening devices to be fixed locally and to float on the layer of flexible material. This layer has a considerable thickness and can compensate for manufacturing tolerances in cooperation with the strong, load-bearing heavy layer.
Schließlich hat dieses einfache aus nur drei Schichten bestehende Bauteil dadurch, daß die Schicht aus biegeweichem Werkstoff unmittelbar zwischen dem Blech der Karosserie und der Schwerschicht angeordnet ist, eine hervorragende schalldämmende Wirkung.After all, this simple component consisting of only three layers has the effect that the layer is made of Pliable material arranged directly between the sheet metal of the body and the heavy layer is, an excellent sound-absorbing effect.

Der Wagenkastenboden 1 besteht aus den Bodenblechen 2. Auf den Bodenblechen 2 ist eine Schicht 3 aus dynamisch weichem Werkstoff angeordnet. Für die Schicht 3 kann eine Glaswollmatte oder eine Matte aus synthetischen oder natürlichen Fasern verwendet werden. Auf der Schicht 3 schwimmt die Schale 4, die aus einem eine textile Oberschicht bildenden Teppich 5 und einer Schwerschicht 6 besteht, für deren Herstellung ein Thermoplast oder eine bitumenhaltige Masse geeignet ist, deren Flächengewicht größer als 4 kg/m2 ist. Die Schale 4 wird durch Tiefziehen oder Pressen des beschichteten Teppichs 5 oder durch Verkleben der vorgeformten Schwerschicht 6 mit dem ebenfalls vorgeformten Teppich 5 hergestellt.The car body floor 1 consists of the floor panels 2. A layer 3 of dynamically soft material is arranged on the floor panels 2. A glass wool mat or a mat made of synthetic or natural fibers can be used for the layer 3. On the layer 3, the shell 4 floats, which consists of a carpet 5 forming a textile top layer and a heavy layer 6, for the production of which a thermoplastic or a bituminous mass is suitable, the surface weight of which is greater than 4 kg / m 2 . The shell 4 is produced by deep-drawing or pressing the coated carpet 5 or by gluing the preformed heavy layer 6 to the likewise preformed carpet 5.
Die mit dem Teppich 5 verbundene Schwerschicht 6 überdeckt auch andere Blechpreßteile, z. B. die Spritzwand 7. Der Abstand zwischen der Schale 4 und den Blechteilen, z. B. 2 und 7, soll mindestensThe heavy layer 6 connected to the carpet 5 also covers other pressed sheet metal parts, e.g. B. the bulkhead 7. The distance between the shell 4 and the sheet metal parts, for. B. 2 and 7, should at least
10 τπττι betragen und kann aber örtlich unterschritten werden, jedoch nicht mehr als 20 0Zo der zur Schalldämpfung herangezogenen Fläche.10 τπττι amount and can be undercut locally, but not more than 20 0 Zo of the area used for sound absorption.
Die Fläche des Teppichs 5 kann auch, wie in F i g. 4 dargestellt, nur örtlich beschichtet sein. Die Schwerschicht 6 und dementsprechend die dynamisch weiche Schicht 3 ist dann beispielsweise nur im Bereich der Spritzwand? und im Bereich der Radkästen 9 und im Abstellbereich 10 der Füße vor den Vordersitzen 11 angebracht An den übrigen, für die Schalldämmung weniger wichtigen Stellen, liegt der TeppichS unmittelbar auf den Bodenblechen 2 auf.The surface of the carpet 5 can also, as in FIG. 4 shown, be coated only locally. the Heavy layer 6 and accordingly the dynamically soft layer 3 is then only in the area, for example the bulkhead? and in the area of the wheel arches 9 and in the storage area 10 of the feet in front of the Front seats 11 attached Carpet S rests directly on the floor panels 2.
