Description

Die Erfindung betrifft einen Streifen zur Durchführung des Verfahrens zur Befestigung einer Glasscheibe an einer Fahrzeugkarosserie, der aus weichen, härtbaren Werkstoffen besteht und einen in Längsrichtung verlaufenden elektrischen Leiter aufweist, wobei der Streifen parallel zum Rand der Scheibe bzw. der Fensteröffnung in der Karosserie angeheftet wird, die Scheibe in die Öffnung so eingesetzt wird, daß der Streifen den Schlitz zwischen beiden abdichtet, die Enden des Leiters an eine elektrische Stromquelle angeschlossen werden und durch diese zur Erzeugung von Wärme Strom geleitet wird, durch die der Streifen infolge Aushärtung in einen zähen, nachgiebigen Zustand übergeführt und die Scheibe mit der Karosserie verbunden wird, nach Patentanmeldung B 76403 VIb /32 b (deutsche Auslegeschrift 1 253 083).
Bei diesem Verfahren kann unter bestimmten Bedingungen, z. B. wenn der Kunststoff zumindest vor dem Gebrauch sehr weich ist und der Streifen einer rauhen Behandlung unterzogen wird, der elektrische Leiter beim Befestigen der Scheibe freigelegt werden und dadurch mit der Karosserie einen Kurzschluß bilden.
Diese Gefahr wird bei dem Streifen gemäß der Erfindung dadurch vermieden, daß der Leiter von einer flexiblen Schutzhülle aus elektrisch isolierendem Material umgeben ist.
Um eine gute Wärmeleitung von dem elektrischen Leiter auf den weichen, härtbaren Werkstoff des Streifens zu gewährleisten, wird die flexible Schutzhülle möglichst so dünn bemessen, wie es die mechanische Festigkeit zuläßt.
Die Schutzhülle kann beispielsweise als Lacküberzug oder als Gewebemantel des Leiters ausgebildet sein. Vorzugsweise ist die Schutzhülle ein kunstharzgebundener Glasfasermantel.
Zweckmäßigerweise ist der Streifen in der nötigen sich um eine vorgegebene Scheibe erstreckenden Länge vorgefertigt, wobei der weiche, härtbare Werkstoff an den Enden des Streifens entfernt ist, um die Leiterenden freizugeben.
Die Erfindung soll an Hand der Zeichnung in Verbindung mit der Befestigung einer Glasscheibe in Form einer Windschutzscheibe an einer Fahrzeugkarosserie näher erläutert werden. Es zeigt
F i g. 1 die Frontansicht der Windschutzscheibe,
F i g. 2 einen Querschnitt der Windschutzscheibe in gegenüber F i g. 1 größerem Maßstab,
F i g. 3 einen Längsschnitt durch einen Teil des Streifens gemäß der Erfindung und
F i g. 4 einen Querschnitt durch den Streifen gemäß der Erfindung.
Ein wärmehärtbares Kunststoffmaterial, das z. B. die in Hauptpatentanmeldung beschriebene Zusammensetzung haben kann, wird zunächst in einem gekühlten Hochleistungsmischer gemischt und dann auf einen von einer Schutzhülle 11 α umgebenen Leiter in Form eines Drahts 11 zur Bildung eines Streifens 10 von etwa 8 mm Durchmesser umhüllend aufgespritzt, wobei die Schutzhüllella aus kunstharzgebundenem Glasfasermaterial besteht und der von der Schutzhülle umgebene Draht 11 den Streifen 10 als Seele durchzieht. Der Draht kann beispielsweise aus einer Legierung von 90%Kupfer und 10 °/o Nickel hergestellt sein sowie einen Durchmesser von 0,6 mm, ein spezifisches Gewicht von 8,95, einen spezifischen Widerstand von 14,1 μΩ ■ cm, einen Widerstand von 0,48 Ω/m und einen Schmelzpunkt von 1100° C aufweisen. Der Streifen 10 ist in der nötigen Lage entsprechend dem Umfang der vorgegebenen Windschutzscheibe vorgefertigt, wobei der Kunststoff und die Schutzhülle 11 α an den Enden des Streifens entfernt sind, so daß die Drahtenden freiliegen.
Nachdem der Rand der Windschutzscheibe 12 und der für die Windschutzscheibe vorgesehenen Öffnung 13 in der Fahrzeugkarosserie 14 gesäubert worden sind, wird der Streifen 10 auf den Rand der Windschutzscheibe 12 aufgesetzt, an der er haften bleibt, weil er mit einer selbstklebenden Oberfläche versehen ist. Der Streifen 10 wird so angeordnet, daß der Rand der Windschutzscheibe 12 vollständig umgeben ist und die Streifenenden sich überkreuzen. Anschließend wird die Windschutzscheibe 12 in die Öffnung 13 eingesetzt. In diesem Zustand wird die Windschutzscheibe 12 durch Anlegen an eine Umrandung 15 der Öffnung 13 oder gewünschtenfalls durch Abstandsstücke 17, beispielsweise aus Gummi, gehalten, die die Windschutzscheibe 12 zentriert halten. Die beiden Enden des Drahts selbst werden dann an eine elektrische Niederspannungsquelle bei einem Spannungsabfall von gewöhnlich 6,7 V/m Streifenlänge angeschlossen, so daß sich der Streifen 10 schnell erwärmt und damit erweicht. Nach dem Erweichen wird die Windschutzscheibe 12 einfach von Hand gegen die Öffnung 13 gedrückt, so daß sich der Streifen 10 zwischen dem Rand der Winschutzscheibe 12 und der Umrandung 15 der Öffnung 13 abflacht, so daß sich eine anhaftende Verbindung ergibt. Nach einer weiteren Erwärmung wird der Leiter 11 α von der Niederspannungsquelle getrennt, da die Wärme den Kunststoff des Streifens 10 ausgehärtet hat und die Haftverbindung stark genug ist, um die Fahrzeugstöße während des Verkehrs auszuhalten. Der Rand der Windschutzscheibe 12, der den Streifen 10 trägt, wird dann mit einem äußeren Formteil 16 abgedeckt.
Gewünschtenf alls kann für den Streifen 10 an Stelle eines wärmehärtbaren Kunststoffs auch ein thermoplastisches Material wie Butylgummi verwendet werden.
