Abstract

The filter includes a flexible and permeable support (a) contg. or a adjacent to chemical sorption agents (b). The support (a) is pref. a fabric or cloth, either of which may be quilted, and esp. contg. waterproof materials, e.g. fibres or similar elements made of ceramics, glass, plastics or metals, and quilted like a mattress to form layers between which agents (b) are located. Different agents (b) may be used in the various layers. Agents (b) are pref. active carbon; and/or active coke; and/or CaCl2; and/or soda lime; and/or a catalyst for CO. The agents may be fixed in or on support (a) as a liq., e.g. NaOH soln.; or as powders; or on expanded granules of Ca-Al-silicate. The catalyst for CO is pref. 60% MnO2, 40% CuO; or 50% MnO2, 30% CuO, 15% cobalt oxide and 5% Ag2O. Air breathed by the driver and passengers is purified from noxious substances even in very dense traffic, etc.

Description

Beschreibung und Erläuterung zur Zusatzpatent-Description and explanation of the additional patent

anmeldung 'Filtervorrichtung für Personenschutz in Kraftfahrzeugen mit nicht feuchtigkeitsaufnehmendem Filtermaterial'.registration 'filter device for personal protection in motor vehicles with non-moisture absorbing filter material '.

Zusatz zu P 28 43 012.8 In der Hauptanmeldung 'Filtervorrichtung für Personenschutz in Kraftfahrzeugen' wird eine Filtervorrichtung beschrieben, die nicht in dem Frischluft-Ansaugkanalsystem angeordnet ist, sondern hinter den Luftaustrittsschlitzen im Wageninneren, und der Filter aus verformbaren, gut atmungsaktiven Filterkissen besteht, die mit chemisorbierenden Massen gefüllt sind und eine gegen Aufprall weich abpolsternde Masse und Kissenform besitzen.Addition to P 28 43 012.8 In the main application 'Filter device for Personal protection in motor vehicles' a filter device is described which is not arranged in the fresh air intake duct system, but behind the air outlet slots inside the car, and the filter made of deformable, well-breathable filter pads consists, which are filled with chemisorbent masses and one soft against impact Have cushioning mass and pillow shape.

Um die Feuchtigkeitsaufnahme im Filter auf ein Minimum zu reduzieren, wird erfindungsgemäß vorgeschlagen, daß das die chemisorbierenden Massen umlagernde Filtermaterial nicht aus Stoffen besteht, die Feuchtigkeit aufnehmen, sondern feuchtigkeitsabstoßend wirken, und somit ein Aufspeichern von Feuchtigkeit im chemisorbierenden Filter durch die Umhüllung vermieden wird, so daß wie bisher bei Übersättigung des Filtermaterials eintieschlagen---der Scheiben nicht mehr möglichüqemacht wird.To reduce moisture absorption in the filter to a minimum, it is proposed according to the invention that the rearrangement of the chemisorbent masses Filter material does not consist of substances that absorb moisture, but rather moisture-repellent act, and thus a storage of moisture in the chemisorbing filter avoided by the envelope so that as before with oversaturation knock in the filter material --- the panes are no longer possible.

Der Sicherheitsnotwendigkeit, plötzlich sich bildende Wasserdämpfe an der Sichtscheibe zu vermeiden, wird durch die erfindungsgemäße Einführung von wasserabstoßendem Material nachgekommen.The need for safety, suddenly forming water vapors to avoid at the viewing window is made possible by the introduction of complied with water-repellent material.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebene Ausbildungsform beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, ein die Chemisorptions massen umhüllendes, luftdurchlässiges, filterndes Material zu verwenden, das aus nicht feuchtigkeits aufnahmefähigen Materialien, wie Keramikfasern oder Kunststoffasern bzw. Glasfasern, besteht.Of course, the invention is not limited to the above in detail Form of training described is limited, but there are numerous changes possible, however, without deviating from the basic idea, a mass of chemisorption to use enveloping, air-permeable, filtering material that is not moisture-absorbing materials, such as ceramic fibers or synthetic fibers or glass fibers.
