Abstract

The ventilation opening (3) in the bellows for the brake booster is covered by one or more filters (2, 4) in a three-dimensional or flat shape. A cylindrical damping element (2) can be fixedly mounted in the upper region of the shaped part and the remaining ventilation openings are covered by a fixed flat surface filter (4). The damping element and filter can be made from open-pore air-permeable foam.

Description

Die Erfindung betrifft ein flexibles Formteil aus einem kompakten Material zur Ab­ deckung längenveränderlicher Systeme, insbesondere Faltenbalg mit mindestens einer Lüftungsöffnung für Bremskraftverstärker.The invention relates to a flexible molded part made from a compact material Covering variable-length systems, especially bellows with at least a ventilation opening for brake booster.

Flexible Formteile der aufgezeigten Gattung sind bekannt. Hierbei werden im allge­ meinen nachträglich die Lüftungsöffnungen mit dafür geeigneten Filterelementen abgedeckt. Neben dieser Zusatzarbeit vor dem Einbau der flexiblen Formteile ist es nachteilig, daß ein paßgenauer Sitz der Formteile nicht gewährleistet ist.Flexible moldings of the type shown are known. Here, in general mean afterwards the ventilation openings with suitable filter elements covered. In addition to this additional work before installing the flexible molded parts, it is disadvantageous that a precise fit of the molded parts is not guaranteed.

Es ist bereits bekannt, flexible Formteile in der Gesamtheit aus Schaum herzustellen. Diese Formteile sind kostenintensiv und besitzen keine ausreichende Schallisolie­ rung, da keine Verdichtung des Schaum-Materials gegeben ist. It is already known to produce flexible molded parts in their entirety from foam. These molded parts are expensive and do not have sufficient sound insulation tion because there is no compression of the foam material.  

Der Erfindung liegt die Aufgabe zugrunde, ein flexibles Formteil nach dem Oberbe­ griff des Hauptanspruchs so auszubilden, daß nachträgliche Montagearbeiten für die Abdeckung der Lüftungsöffnungen entfallen bei Gewährleistung einer paßgenauen Anordnung der Abdeckungen.The invention has for its object a flexible molded part according to the Oberbe handle the main claim so that subsequent assembly work for the Covering the ventilation openings is not required if a precise fit is guaranteed Arrangement of the covers.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lüftungsöffnung bzw. die Lüftungsöffnungen durch einen bzw. mehrere Filter in räumlicher oder flächiger Form abgedeckt sind. In Ausgestaltung der Erfindung ist im oberen Bereich des fle­ xiblen Formteils ein zylinderförmiges Dämpfungselement fest angeordnet. Die übri­ gen Lüftungsöffnungen können durch einen fest angeordneten Filter abgedeckt sein, wobei das Dämpfungselement und der Filter in definiert festgelegter Lage fixiert sind. In Ausgestaltung der Erfindung sind das zylinderförmige Dämpfungselement und der Filter aus offenporigem luftdurchlässigen Schaum gebildet, wobei der Schaum vorteilhafterweise verdichtet ist und dadurch eine verbesserte Schallisolie­ rung erreichbar ist.This object is achieved in that the ventilation opening or the ventilation openings through one or more filters in spatial or area Form are covered. In an embodiment of the invention is in the upper region of the fle xiblen molded part, a cylindrical damping element fixed. The rest ventilation openings can be covered by a fixed filter, the damping element and the filter being fixed in a defined position are. In an embodiment of the invention, the cylindrical damping element and the filter is formed from open-pore air-permeable foam, the Foam is advantageously compressed and thereby improved sound insulation tion is available.

Es besteht die Möglichkeit, zur Herstellung der festen Verbindung Befestigungsstifte anzuordnen oder die Halterung durch einen Hinterschnitt bzw. durch Kleben herzu­ stellen. Bei einer bevorzugten Ausbildung sind die Schaumteile eingespritzt.There is the possibility of using fixing pins to make the fixed connection to arrange or the bracket by an undercut or by gluing put. In a preferred embodiment, the foam parts are injected.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben. Die einzige Figur zeigt einen Vertikalschnitt durch einen Faltenbalg.An embodiment of the invention is shown in the drawing and will described in more detail below. The only figure shows a vertical section through a bellows.

Das flexible Formteil ist durch einen Faltenbalg 1 gebildet. Im oberen Bereich des Faltenbalgs 1 ist zur Schallisolierung ein Dämpfungselement 2 fest angeordnet. Zur Fixierung in der festgelegten Lage dienen Befestigungsstifte 5. Die Lüftungsöff­ nungen 3 sind durch einen Filter 4 abgedeckt, der durch einen Hinterschnitt 6 gehal­ tert ist. The flexible molded part is formed by a bellows 1 . In the upper area of the bellows 1 , a damping element 2 is fixedly arranged for sound insulation. Fastening pins 5 are used for fixing in the specified position. The ventilation openings 3 are covered by a filter 4 which is held by an undercut 6 .
