Abstract

The cpd. glass, esp. for vehicle windows, has an inner glass pane (3) with a thickness which is a multiple of the thickness of the outer glass pane (1). The adhesive layer (4), to bond the glass panes (1, 3) together, is of PVB.

Description

Die Erfindung betrifft eine Verbundglasscheibe, insbeson­ dere für Fahrzeuge, mit den im Oberbegriff des Pa­ tentanspruches 1 angegebenen Merkmalen.The invention relates to a laminated glass pane, in particular for vehicles with which in the preamble of Pa Tent Claim 1 specified features.

Eine derartige, durch die DE-OS 19 54 920 bekannte Ver­ bundglasscheibe weist zwei Glasscheiben auf, die über eine durchsichtige Schicht aus Kunststoff miteinander verbunden sind. Die Glasscheiben können eine Dicke zwi­ schen 0,5 und 3 mm aufweisen und sind nach den Ausfüh­ rungsbeispielen mit gleicher Dicke gefertigt. Ist die Verbundglasscheibe an einem Kraftfahrzeug vorgesehen, so kann beispielsweise vom Fahrtwind vorausfahrender Fahr­ zeuge aufgewirbelter Sand oder Staub hart gegen die äußere Glasscheibe schlagen und zumindest nach einiger Zeit die Oberfläche beschädigen. Derartige Schäden an der äußeren Glasscheibe der Verbundglasscheibe können bei einfallenden Lichtstrahlen unerwünschtes Streulicht ver­ ursachen. Außerdem wird die Festigkeit der Verbundglas­ scheibe beeinträchtigt, die beispielsweise bei Verwendung an einem Kraftfahrzeug ein tragendes Bauteil ist.Such Ver, known from DE-OS 19 54 920 Bundglasglas has two glass panes that over a transparent layer of plastic with each other are connected. The glass panes can have a thickness between have 0.5 and 3 mm and are according to the execution Example with the same thickness. Is the Laminated glass pane provided on a motor vehicle, so can drive ahead of the wind, for example test sand or dust hard against the hit outer glass pane and at least after some Time damage the surface. Such damage to the outer glass pane of the laminated glass pane can incident light rays unwanted stray light ver causes. It also strengthens the laminated glass disc impaired, for example, when using is a load-bearing component on a motor vehicle.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbund­ glasscheibe mit den im Oberbegriff des Patentanspruches 1 angegebenen Merkmalen zu schaffen, die eine höhere mecha­ nische Beständigkeit gegenüber aufprallenden Teilchen aufweist.The invention has for its object a composite Glass pane with the in the preamble of claim 1  to provide specified features that a higher mecha nical resistance to impacting particles having.

Diese Aufgabe ist durch die im Patentanspruch 1 angegebe­ nen Merkmale gelöst.This object is indicated by the in claim 1 Features resolved.

Der mit der Erfindung erreichbare Vorteil ist im wesent­ lichen darin zu sehen, daß die verhältnismäßig dünne äußere Glasscheibe durch ihre geringe Dicke bei auf­ prallenden Teilchen wie Sand, Staub oder kleinen Steinen ausweichen und sich durch die Kunststoffschicht elastisch verformen kann, die ihrerseits von der verhältnismäßig dicken inneren Glasscheibe gestützt ist. Die äußere Glas­ scheibe wird somit weniger im mikroskopischen Bereich be­ schädigt, wodurch bei einfallendem Licht kaum oder kein Streulicht an der Verbundglasscheibe entsteht. Die Ab­ stützung der äußeren Glasscheibe erfolgt über eine ela­ stische, durchsichtige Kunststoffschicht, die beispiels­ weise durch eine Kunststoffolie aus Polyvinylbutyral (PVB) mit einer Dicke von beispielsweise 0,76 mm gebildet sein kann, die für den Schichtaufbau üblicher Verbund­ glasscheiben verwendet wird. Ein elastisches Ausweichen der äußeren Glasscheibe bei aufprallenden Teilchen wird erreicht, wenn die innere Glasscheibe eine wenigstens doppelte Dicke gegenüber der äußeren Glasscheibe aufweist und die Kunststoffschicht eine für die geforderte Nach­ giebigkeit der äußeren Glasscheibe ausreichende Dicke und Elastizität aufweist.The advantage achievable with the invention is essential lichen to see that the relatively thin outer glass pane due to its small thickness bouncing particles such as sand, dust or small stones dodge and become elastic through the plastic layer can deform, which in turn from the proportionately thick inner glass pane is supported. The outer glass disc is thus less in the microscopic range damage, which means little or no light Stray light is generated on the laminated glass pane. The Ab the outer glass pane is supported by an ela tical, transparent plastic layer, for example wise through a plastic film made of polyvinyl butyral (PVB) with a thickness of, for example, 0.76 mm can be the usual composite for the layer structure glass panes is used. An elastic dodge the outer glass pane in the case of impacting particles reached when the inner glass pane at least one has twice the thickness of the outer glass pane and the plastic layer one for the required night flexibility of the outer glass pane sufficient thickness and Has elasticity.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegen­ stand von Unteransprüchen.Advantageous embodiments of the invention are counter stood by subclaims.

Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung mit einer einzigen Figur näher erläutert. An embodiment of the invention is based on a Drawing explained with a single figure.  

In der einzigen Figur ist ein Querschnitt durch eine Windschutzscheibe eines Kraftfahrzeugs dargestellt, die zwischen einer äußeren Glasscheibe 1 und einer dem Fahr­ gastraum 2 des Fahrzeugs zugewandten inneren Glasscheibe 3 eine elastische, durchsichtige Kunststoffschicht 4 auf­ weist. Die äußere Glasscheibe 1 und die innere Glas­ scheibe 3 bilden Außenflächen der Verbundglasscheibe, wo­ bei die dazwischen vorgesehene Kunststoffschicht 4 unmit­ telbar an den Glasscheiben 1, 3 anliegt. Bei der vorlie­ genden Ausführung weist die äußere Glasscheibe 1 eine Dicke von 0,2 mm auf. Die innere Glasscheibe 3 ist mit einer Dicke von 2,1 mm gefertigt und weist somit gegen­ über der äußeren Glasscheibe 1 eine mehrfache Dicke auf. Durch die verhältnismäßig dünne äußere Glasscheibe 1 ist im vorliegenden Fall das Gewicht der Verbundglasscheibe gegenüber üblichen Ausführungen vermindert und dennoch die Festigkeit der Verbundglasscheibe erhöht.In the single figure is a cross-section through a windscreen of a motor vehicle, the facing between an outer glass pane 1 and the running guest room 2 of the vehicle inner glass sheet 3 is a flexible, transparent plastic layer 4 has. The outer glass pane 1 and the inner glass pane 3 form outer surfaces of the laminated glass pane, where the plastic layer 4 provided therebetween directly abuts the glass panes 1 , 3 . In the vorlie version, the outer glass sheet 1 has a thickness of 0.2 mm. The inner glass pane 3 is made with a thickness of 2.1 mm and thus has a multiple thickness compared to the outer glass pane 1 . Due to the relatively thin outer glass pane 1 , the weight of the laminated glass pane is reduced in the present case compared to conventional designs, and yet the strength of the laminated glass pane is increased.

Die Erfindung ist auch in anderen Ausführungen realisier­ bar, bei denen die äußere Glasscheibe eine Dicke zwischen etwa 0,1 bis 1,0 mm aufweist und die innere Glasscheibe mit einer aus Gewichtsgründen geringen, jedoch größeren Dicke als etwa 2 mm gefertigt ist. Die Dicke der elasti­ schen Kunststoffschicht ist von dem verwendeten Werkstoff abhängig. Ist die Kunststoffschicht beispielsweise eine Folie aus Polyvinylbutyral (PVB), so kann diese Schicht eine übliche Dicke von etwa 0,76 mm aufweisen. Es ist nicht erforderlich, daß die Verbundglasscheibe lediglich drei Schichten aufweist. Selbstverständlich können auch mehr als drei Schichten vorgesehen sein, von denen eine innere Glasscheibe, die keine Außenfläche der Verbund­ glasscheibe bilden muß, eine mehrfache, wenigstens dop­ pelte Dicke gegenüber der äußeren Glasscheibe aufweist.The invention is also realizable in other versions bar, in which the outer glass pane has a thickness between has about 0.1 to 1.0 mm and the inner glass pane with a small but larger for weight reasons Thickness than about 2 mm is made. The thickness of the elasti The plastic layer is of the material used dependent. For example, if the plastic layer is one Polyvinyl butyral (PVB) film, so this layer have a usual thickness of about 0.76 mm. It is not required that the laminated glass pane only has three layers. Of course you can too more than three layers may be provided, one of which inner glass pane that has no outer surface of the composite glass pane must form a multiple, at least dop pelte thickness compared to the outer glass pane.
