Abstract

A vehicle safety window pane fastening, quickly separable by pyrotechnic means, has an adhesive layer 3 which fixes the window pane 2 in an associated aperture of the motor vehicle and which is connected operatively to a pyrotechnic means 5, in such a way that the holding function of the said adhesive layer 3 is cancelled as a result of ignition of the pyrotechnic means 5.

Description

Die Erfindung betrifft ein mit pyrotechnischen Mitteln schnell trennbares Befestigungselement einer Kraftfahrzeug- Fensterscheibe.The invention relates to a pyrotechnic agent fast separable fastener of a motor vehicle Window pane.

Bei Fahrzeugen mit einer Sicherheitsverglasung soll zumindest eine Fensterscheibe in einem unfallbedingten Notfall gewollt nach außen aus ihrer Befestigung lösbar sein. Der Trennvor­ gang soll beispielsweise von in Not geratenen Fahrzeugin­ sassen bewußt und in kurzer Zeit und gezielt bewirkt werden können.In vehicles with safety glazing at least wanted a window in an accident related to an accident be detachable from the outside of their attachment. The separator For example, the gang should drive from a vehicle in need sat consciously and in a short time and be brought about in a targeted manner can.

Ein im vorgenannten Sinne betätigbares aufsprengbares Befe­ stigungselement ist aus DE 37 35 133 A1 bekannt. Dieses be­ kannte Befestigungselement ist eine aufsprengbare Rahmenan­ ordnung, in der die Sicherheits-Fensterscheibe durch Klemm­ wirkung gedichtet gehalten ist. Diese Rahmenkonstruktion be­ sitzt einen komplizierten Aufbau und benötigt einen relativ großen Platzbedarf.A detachable device that can be operated in the aforementioned sense Stigungselement is known from DE 37 35 133 A1. This be Known fastener is a snap-open frame order in which the safety window pane by clamping effect is kept sealed. This frame construction be sits a complicated structure and needs one relatively large space requirement.

Hier eine Verbesserung zu schaffen, ist das Problem, mit dem sich die Erfindung beschäftigt und das sie durch ein gat­ tungsgemäßes Befestigungselement mit den kennzeichnenden Merkmalen des Patentanspruchs 1 löst.Creating an improvement here is the problem with the invention is concerned and that it through a gat Fixing element with the characteristic Features of claim 1 solves.

Die Erfindung beruht auf dem Gedanken, die Fensterscheibe praktisch allein durch eine an ihrem Umfang umlaufende Klebe­ schicht an einem die Scheibe aufnehmenden Öffnungsrand zu fi­ xieren und diese Fixierung im Notfall mit pyrotechnischen Mitteln schnellstmöglich zu lösen. Hierzu ist es lediglich erforderlich, die Klebeschicht derart direkt mit einem pyro­ technischen Mittel in Wirkverbindung zu bringen, daß durch ein Zünden dieses Mittels die fixierende Funktion der Klebe­ schicht aufgehoben wird. Das pyrotechnische Mittel wirkt der­ art, daß in erster Linie durch eine hohe Gas- und Hitzeent­ wicklung die Struktur der Klebeschicht zerstört wird.The invention is based on the idea of the window pane practically solely by a circumferential adhesive layer on an opening edge receiving the pane xieren and this fixation in an emergency with pyrotechnic To solve means as quickly as possible. For this it is only required, the adhesive layer directly with a pyro technical means to bring that into effect igniting this agent the fixing function of the adhesive layer is lifted. The pyrotechnic agent works art that primarily due to high gas and heat ent the structure of the adhesive layer is destroyed.

Bei einer zweckmäßigen Ausgestaltung der Erfindung ist das pyrotechnische Mittel direkt in das Innere der Klebeschicht eingebettet und läuft mit dieser um. Das pyrotechnische Mit­ tel ist dabei jeweils mit einer Zündeinrichtung verbunden, die bewußt betätigt oder automatisch ausgelöst werden kann.In an expedient embodiment of the invention that is pyrotechnic agents directly into the interior of the adhesive layer embedded and running around with it. The pyrotechnic with tel is connected to an ignition device, which can be consciously activated or triggered automatically.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is in the drawing shown.

Diese zeigt einen Schnitt durch eine Klebebefestigung einer Sicherheitsscheibe an dem Rahmen einer Fahrzeugöffnung. This shows a section through an adhesive fastener Safety window on the frame of a vehicle opening.  

An dem Rahmen 1 einer Öffnung eines Kraftfahrzeuges ist eine Sicherheits-Fensterscheibe 2 über eine Klebeschicht 3 befe­ stigt.On the frame 1 of an opening of a motor vehicle is Stigt a security window plate 2 via an adhesive layer 3 BEFE.

Die Fensterscheibe 2 weist mit ihrer Oberfläche 4 nach außen, das heißt zur Atmosphäre. Innerhalb der Klebeschicht 3 ver­ läuft entlang des Umfanges der Fensterscheibe 2 ein pyrotech­ nisches Mittel 5 in der Form einer Schnur um. Diese Sprengschnur ist im Fahrzeuginneren mit einer Zündeinrichtung ver­ bunden.The surface of the window pane 2 faces 4 , that is to say towards the atmosphere. Within the adhesive layer 3 ver runs along the circumference of the window pane 2, a pyrotechnic agent 5 in the form of a cord. This detonating cord is connected to an ignition device in the interior of the vehicle.

Bei einem Zünden des pyrotechnischen Mittels 5 wird die Kle­ beschicht 3 derart zerstört und in ihrer Funktion aufgehoben, daß die Fensterscheibe entweder nur noch getrennt in der Öff­ nung des Rahmens 1 liegt oder - jeweils bedingt durch die Fahrzeuglage - von selber nach außen aus dem Rahmen 1 heraus­ fällt. Ein zwischen dem Rahmen 1 und der Fensterscheibe 2 liegender Spalt, in dem sich die Klebeschicht 3 befindet, ist nach außen durch eine in der Zeichnung lediglich angedeutete Profilleiste 6 abgedeckt.When the pyrotechnic agent 5 is ignited, the adhesive coating 3 is destroyed and its function is canceled in such a way that the window pane is either only separated in the opening of the frame 1 or - in each case due to the vehicle position - from the outside itself from the frame 1 falls out. A gap between the frame 1 and the window pane 2 , in which the adhesive layer 3 is located, is covered to the outside by a profile strip 6, which is only indicated in the drawing.

Die Erfindung ermöglicht eine denkbar einfache in einem Not­ fall leicht und wirksam aufsprengbare Befestigung einer Si­ cherheits-Fensterscheibe.The invention enables a very simple in an emergency case easy and effective detachable attachment of a Si security window.
