Abstract

The Parent Patent described a filter for the passenger compartment of motor cars in which filter pads are coated with a washable elastic layer. The new filter has pref. on the contaminated air inlet side several shapes of contact chambers of triangular, rectangular or semicircular section which are filled with a catalyst contact mass and bounded by filtering surfaces. The rest of the filter pad is filled with chemisorption and catalyst materials which respond to other toxic substances. The whole is enclosed in a washable skin which also acts as a filter and is attached to the dashboard. Vibrations can thus not displace the filling and the filter responds to more than one contaminant.

Description

Beschreibung und Erläuterung zur Zusatz-Description and explanation of the additional

patent- und Hilfsgebrauchsmusteranmeldung 'Flexibler, verformbarer Mehrkammer-Autofilter'.patent and utility model registration 'More flexible, more malleable Multi-chamber auto filter '.

Zusatz zu P 28 43 012.8 In der Hauptpatentanmeldung wird eine Filtervorrichtung für den Personenschutz in Kraftfahrzeugen beschrieben, die erfindungsgemäß hinter den Luftaustrittsschlitzen im Wageninneren angeordnet ist und selber aus atmungsaktiven, verformbaren Filterkissen besteht, die mit chemisorbierenden Massen gefüllt sind und gegen Aufprall eine weich abpolsternde Masse und Kissenform besitzen, die mit einem vorzugsweise elastischen, abwaschbaren, atmungsaktiven Überzug versehen ist und mit leicht lösbaren Verbindungen abdichtend um die Luftschlitze angeordnet ist.Addition to P 28 43 012.8 In the main patent application a filter device for personal protection in motor vehicles described, according to the invention behind the air outlet slots inside the car and made of breathable, deformable filter pads, which are filled with chemisorbent masses and have a soft cushioning mass and cushion shape against impact, which with a preferably elastic, washable, breathable cover is provided and is arranged sealingly around the air slots with easily detachable connections.

Nachstehend wird diese erfindungsgemäße Vorrichtung durch weitere erfindungsgemäße Merkmale wesentlich verbessert.This device according to the invention is described below by further features according to the invention significantly improved.

Zur Abscheidung von Schadstaffen, die bei stark befahrener Autobahn oder im Stadtverkehr z. B. entstehen, wie N0x, Benzpiren, Kohlenwasserstoffe, CO usw., ist es erforderlich, chemisorbierende Massen in das kissenartige, verformbare Filter einzulegeñ, die auf die unterschiedlichen Schadstoffe ansprechen.For the separation of harmful substances that occur on busy motorways or in city traffic z. B. arise, such as N0x, Benzpiren, hydrocarbons, CO etc., it is necessary to convert chemisorbent masses into the pillow-like, deformable Insert filters that respond to the various pollutants.

Das-Vermischeh von Massen mit unterschiedlicher Chemisörptionsfähigkeit bringt nicht den gewünschten Erfolg, da die chemisorbierenden Massen nicht gleichartig wirkend über die gesamte Palette des Schadstoffangebots reagieren.The mixing of masses with different chemisorption capacity does not bring the desired success, since the chemisorbent masses are not homogeneous react effectively across the entire range of pollutants.

Das Übereinanderlegen von mehreren unterschiedlichen Chemisorptionsmassen ist möglich und wurde auch bereits mit Erfolg praktiziert. Jedoch ist die Austauschfläche der Berührungslagen bei einer normalen aufeinanderfolgenden schichtweisen Aufstockung nicht optimal, bezogen auf die Berührungskontaktflächen von einer chemisorbierenden Masse zur Nächstanl iegenden.The superposition of several different chemisorption materials is possible and has already been practiced with success. However, the exchange area is of the contact positions in the case of a normal, successive build-up in layers not optimal, based on the touch contact surfaces of a chemisorbent Ground to the next adjoining.

Um diese Kontaktberührungsflächen der unterschiedlichen Chemisorptionsmassen größtmöglich zu gestalten und gleichzeitig ein Verrutschen der Massen gegeneinander weitgehendst beim ständig durch Rüttelbewegung im Fahrzeug eingebauten Autofilter bestmöglich zu verhindern, wird erfindungsgemäß vorgeschlagen, einen flexibel verformbaren Mehrkammerautofilter zu verwenden, der erfindungsgemäß vorzugsweise der beiliegenden Zeichnung ähnelt.Around these contact surfaces of the different chemisorption masses to make it as large as possible and at the same time the masses slipping against each other largely with the car filter installed in the vehicle by constantly shaking To prevent it as best as possible, the invention proposes a flexibly deformable one To use multi-chamber car filter, according to the invention preferably the enclosed Drawing resembles.

In der beiliegenden Zeichnung ist dargestellt: mit 1) das ankommende Rohgas z. B. aus dem Belüftungsschlitz oberhalb des Armaturenbretts; mit 2) das austretende Reingas in die Kraftfahrzeugkabine, z. B. im Bereich des Frontfensters; mit 3, 4 u. 5) die ersten Kontaktkammern, die z. B. mit Katalysatorkontaktmasse gefüllt sind; Diese Kammern zeigen profilierte Formen, z. B. Kästen in runder oder spitzwinkeliger Ausführung und haben dadurch erfindungsgemäß mit 6) größtmögliche Berührungsflächen, die als Filtertrennflächen ausgebildet sind und in der zweiten Kammer 7) als Bodenbewehrung dienen, wobei in der zweiten Kammer z. B.The attached drawing shows: with 1) the incoming Raw gas z. B. from the ventilation slot above the dashboard; with 2) that escaping clean gas into the vehicle cabin, e.g. B. in the area of the front window; with 3, 4 and 5) the first contact chambers, the z. B. with catalyst contact mass are filled; These chambers show profiled shapes, e.g. B. Boxes in a round or acute-angled design and thus have according to the invention 6) largest possible contact surfaces, which are designed as filter separation surfaces and in the second chamber 7) serve as soil reinforcement, in the second chamber z. B.

Chemisorptions- und Katalysatormassen eingelagert sind, die auf andere Schadstoffe ansprechen als die Massen, die in der ersten Kammer eingelagert sind. Chemisorption and catalyst masses are incorporated, which on other Pollutants respond as the masses that are stored in the first chamber.

Die Begrenzungsflächen 8) sind ebenfalls als Filtertrennflåchen ausgebildet und z. B. entsprechend dem Hauptpatent mit einer elastischen, abwaschbaren Überhaut versehen, die ebenfalls wie das flexible, verformbare Mehrkammerautofilterpaket mit gut abdichtenden, leicht aufzubringenden und lösbaren Klebe- oder Klettenschlußverbindungen mit dem Armaturenbrett befestigt ist.The boundary surfaces 8) are also designed as filter separating surfaces and Z. B. according to the main patent with an elastic, washable outer skin which also like the flexible, deformable multi-chamber car filter package with well-sealing, easy-to-apply and detachable adhesive or Velcro connections attached to the dashboard.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Autofilter nach den Merkmalen des Hauptpatents, Aktenzeichen P 28 43 012.8, so auszubilden, daß er als flexibler, verformbarer Mehrkammerautofilter ausgebildet ist, wobei die Kammern rechtwinkelige, spitze oder gewellte Formen aufweisen und somit größtmögliche Berührungsflächen der übereinander~ und nebeneinanderliegenden Kammern, die mit unterschiedlichen Chemisorptionsmassen gefüllt sind, garantiert werden.Of course, the invention is not limited to the above in detail The forms of training described are limited, but there are numerous changes possible, but without deviating from the basic idea, an auto filter according to the Features of the main patent, file number P 28 43 012.8, so that it can be used as flexible, deformable multi-chamber car filter is formed, wherein the chambers have right-angled, pointed or wavy shapes and thus the largest possible contact surfaces of the superimposed and adjacent chambers with different Chemisorptionsmassen are filled, can be guaranteed.
