Definitions

  • the invention relates to a laminated glass pane and a use of the laminated glass pane in a vehicle.
  • windows In an emergency, windows often serve as an escape or rescue route. In order to prevent injuries when exiting or entering through a window in an emergency, windows can be designed as single-pane safety glass.
  • the toughened safety glass crumbles after breakage and falls to the ground in small glass splinters with few or no sharp edges.
  • Laminated glass panes are used for windows with an increased need for load-bearing capacity or stability.
  • the composite glass panes are characterized in that they continue to have a load-bearing capacity or stability in the event of a break.
  • the glass panes of the laminated glass panes are held in the composite by means of an intermediate layer, in particular also in a broken state.
  • the glass panes must be destroyed and the intermediate layer must be severed. Since the intermediate layer is designed to maintain load-bearing capacity or stability even if the glass panes break, severing the intermediate layer requires a great deal of force. Normally, this severing can only be done with a suitable tool. Particularly in an emergency, this harbors a high risk of injury and safety risks for the people or rescue workers endangered by the emergency.
  • the invention is based on the object of providing a laminated glass pane with improved properties for use as an escape route.
  • the invention provides that at least two pane parts can be separated from a remaining part of the laminated glass pane along at least one open fracture track.
  • breaking trace should be understood to mean a trace of one or more predetermined breaking points which is / are formed from a continuous reduction or a series of reductions in the tear strength of the at least one intermediate layer.
  • An "open fracture track” is to be understood as a fracture track that is not closed. Such a fracture track has at least two ends the at least two disc parts are prevented.
  • the laminated glass pane must be mechanically broken.
  • the composite glass pane has a marked predetermined breaking point for this case.
  • the predetermined breaking point can be struck in a manner known per se by means of an initiator hammer.
  • a continuous split break of the laminated glass pane can thus be brought about with little effort.
  • at least 85% of all glass splinters in the laminated glass pane are preferably materially bonded to the intermediate layer. Here- this can minimize the risk of injury from loose glass splinters.
  • the glass panes of the laminated glass pane are designed as float glass or partially toughened glass.
  • the glass panes of the laminated glass pane are particularly preferably designed as single-pane safety glass panes. The risk of injury can be minimized by designing the glass panes as single-pane safety glass panes. Sharp edges can be avoided if the glass panes break.
  • the laminated glass pane can be designed to be flat or curved.
  • the laminated glass pane can have any external geometry or circumferential geometry. It can therefore advantageously be used in a variety of ways.
  • the laminated glass pane can be produced as required.

  • the airbag system or the tube system is preferably provided in each case to automatically separate at least one pane from the remaining part of the laminated glass pane. In this case, there is no need for a person to apply force to separate one part of the disc of the at least two parts of the disc.
  • the reduction in tear strength is preferably embodied as a mechanical weakening of the intermediate layer.
  • the mechanical weakening is particularly preferably designed as a recess in the intermediate layer. It is also conceivable that the tear strength is reduced by means of an optical or chemical process.
  • a material of the intermediate layer is replaced by a material with, compared to the intermediate layer, reduced tear strength along the at least one breakage track.
  • This can lovable tear resistance can be realized.
  • a weakening of the intermediate layer can be kept ring in a simple manner and thus the stability of the composite glass pane can be increased.
  • An undesirable impairment of the tear strength along the at least one breakage track during a process step of the manufacturing process can be prevented. For example, a melting together of constituents of the intermediate layer can be prevented.
  • the intermediate layer preferably has a reduction in tear strength compared to surrounding areas of the intermediate layer of at least 60%, particularly preferably at least 80% and very particularly preferably 100%.
  • the disc part can easily be separated even by people with little strength, small stature or smaller injuries.

  • the at least two pane parts can be separated off independently of one another.
  • Each of the at least two pane parts can be separated as escape and rescue routes without being influenced by a state of another of the at least two pane parts. If access to one of the at least two pane parts is difficult, the remaining pane parts of the at least two pane parts can be separated by themselves.
  • the at least one breakage track has a breakage track section along which the at least two pane parts border one another.
  • the breakage track section has a length of at least 10%, preferably at least 15% and particularly preferably at least 20% of a total length of the breakage track. The larger the common section, the lower the force required to separate a white direct disk part of the at least two disk parts.

  • "Can be separated without tools” means that the at least two pane parts can each be separated by an operator with a force that can typically be applied by hand, so that no additional means are required to separate out the respective pane part a reliable possibility of self-rescue can be created for individuals in an emergency situation.After the pane has been destroyed by means of the initiator hammer, no further means for separating the at least two pane parts are therefore required.
  • At least two of the at least two disk parts have surfaces of different sizes. This enables an asymmetrical embodiment, which can be advantageous in a particular application.
  • a “surface” is to be understood as an upper surface of a disk part of the at least two disk parts in an undamaged state of the disk part.
  • an area ratio between an upper surface of a smaller pane part of the at least two pane parts in a separated state and a surface Area of a larger disc part of the at least two disc parts in a separated state is greater than 0.2 and particularly preferably greater than 0.4.

Description

Beschreibung description
Verbundglasscheibe für ein Fahrzeug Laminated glass for a vehicle
Die Erfindung betrifft eine Verbundglasscheibe und eine Ver wendung der Verbundglasscheibe in einem Fahrzeug. The invention relates to a laminated glass pane and a use of the laminated glass pane in a vehicle.
In einem Notfall dienen Fenster oftmals als ein Flucht- oder Rettungsweg. Um Verletzungen bei einem Aus- oder Einstieg durch ein Fenster in einem Notfall zu verhindern, können Fenster als Einscheibensicherheitsglas ausgebildet sein. Das Einscheibensicherheitsglas zerbröselt nach dem Bruch und fällt in kleinen Glassplittern, welche wenig bis keine schar fen Kanten aufweisen, zu Boden. Bei Fenstern mit einem erhöh ten Bedarf an Tragfähigkeit oder Stabilität werden Verbund glasscheiben eingesetzt. Die Verbundglasscheiben zeichnen sich dadurch aus, dass diese bei einem Bruch weiterhin eine Tragfähigkeit bzw. eine Stabilität aufweisen. Die Glasschei ben der Verbundglasscheiben werden, insbesondere auch in ei nem gebrochenen Zustand, mittels einer Zwischenschicht im Verbund gehalten. Damit eine Verbundglasscheibe in einem Not fall geöffnet werden kann, ist eine Zerstörung der Glasschei ben und eine Durchtrennung der Zwischenschicht erforderlich. Da die Zwischenschicht dahingehend ausgelegt ist, auch bei einem Bruch der Glasscheiben eine Tragfähigkeit oder Stabili tät zu wahren, erfordert eine Durchtrennung der Zwischen schicht einen hohen Kraftaufwand. Im Normalfall ist diese Durchtrennung nur mit geeignetem Werkzeug zu bewerkstelligen. Dies birgt, insbesondere in einem Notfall, hohe Verletzungs gefahren und Sicherheitsrisiken für die durch den Notfall ge fährdeten Personen oder Rettungskräfte. In an emergency, windows often serve as an escape or rescue route. In order to prevent injuries when exiting or entering through a window in an emergency, windows can be designed as single-pane safety glass. The toughened safety glass crumbles after breakage and falls to the ground in small glass splinters with few or no sharp edges. Laminated glass panes are used for windows with an increased need for load-bearing capacity or stability. The composite glass panes are characterized in that they continue to have a load-bearing capacity or stability in the event of a break. The glass panes of the laminated glass panes are held in the composite by means of an intermediate layer, in particular also in a broken state. So that a laminated glass pane can be opened in an emergency, the glass panes must be destroyed and the intermediate layer must be severed. Since the intermediate layer is designed to maintain load-bearing capacity or stability even if the glass panes break, severing the intermediate layer requires a great deal of force. Normally, this severing can only be done with a suitable tool. Particularly in an emergency, this harbors a high risk of injury and safety risks for the people or rescue workers endangered by the emergency.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbundglas scheibe mit verbesserten Eigenschaften für den Einsatz als Flucht- und Rettungsweg bereitzustellen. The invention is based on the object of providing a laminated glass pane with improved properties for use as an escape route.
Diese Aufgabe wird gelöst durch eine Verbundglasscheibe mit den Merkmalen des Anspruchs 1. Des Weiteren liegt der Erfindung die Aufgabe zugrunde,This object is achieved by a laminated glass pane with the features of claim 1. Furthermore, the invention is based on the object
Flucht- und Rettungswege in einem Fahrzeug mit verbesserten Eigenschaften im Hinblick auf eine Sicherheit für Fahrzeugin sassen bereit zu stellen. To provide escape and rescue routes in a vehicle with improved properties in terms of safety for vehicle occupants.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des ne bengeordneten Verwendungsanspruchs gelöst. According to the invention, this object is achieved by the features of the neighboring use claim.
Vorteilhafte Weiterbildungen der vorliegenden Erfindung kön nen jeweils abhängigen Unteransprüchen entnommen werden. Advantageous developments of the present invention can be found in the dependent subclaims.
Die Erfindung sieht vor, dass entlang wenigstens einer offe nen Bruchspur zumindest zwei Scheibenteile von einem übrigen Teil der Verbundglasscheibe abtrennbar sind. The invention provides that at least two pane parts can be separated from a remaining part of the laminated glass pane along at least one open fracture track.
Unter einer „Bruchspur" soll eine Spur von einer oder mehre ren Sollbruchstellen verstanden werden, die aus einer durch gehenden Reduzierung oder einer Aneinanderreihung von Redu zierungen in der Reißfestigkeit der zumindest einen Zwischen schicht ausgebildet ist/sind. A “breaking trace” should be understood to mean a trace of one or more predetermined breaking points which is / are formed from a continuous reduction or a series of reductions in the tear strength of the at least one intermediate layer.
Unter einer „offenen Bruchspur" soll eine Bruchspur verstan den werden, die nicht geschlossen ist. Solch eine Bruchspur weist wenigstens zwei Enden auf. Mittels der derart ausge stalteten Bruchspur ist ein geringerer Kraftaufwand zur Austrennung der Scheibenteile erforderlich. Des Weiteren kann hierdurch ein Herausfallen eines der zumindest zwei Scheiben teile verhindert werden. An "open fracture track" is to be understood as a fracture track that is not closed. Such a fracture track has at least two ends the at least two disc parts are prevented.
Damit ein Scheibenteil der zumindest zwei Scheibenteile ent lang der Bruchspur abtrennbar ist, muss die Verbundglasschei be mechanisch gebrochen werden. Insbesondere weist die Ver bundglasscheibe für diesen Fall eine markierte Sollbruchstel le auf. Die Sollbruchstelle kann auf eine an sich bekannte Weise mittels eines Initiatorhammers eingeschlagen werden. Somit kann mit geringem Kraftaufwand ein durchgängiger Split terbruch der Verbundglasscheibe herbeigeführt werden. In ei nem gebrochenen Zustand der Verbundglasscheibe sind vorzugs weise zumindest 85 % aller Glassplitter der Verbundglasschei be stoffschlüssig mit der Zwischenschicht verbunden. Hier- durch kann eine Verletzungsgefahr durch lose Glassplitter mi nimiert werden. So that a pane of the at least two pane parts can be separated along the breakage track, the laminated glass pane must be mechanically broken. In particular, the composite glass pane has a marked predetermined breaking point for this case. The predetermined breaking point can be struck in a manner known per se by means of an initiator hammer. A continuous split break of the laminated glass pane can thus be brought about with little effort. In a broken state of the laminated glass pane, at least 85% of all glass splinters in the laminated glass pane are preferably materially bonded to the intermediate layer. Here- this can minimize the risk of injury from loose glass splinters.
Insbesondere sind die Glasscheiben der Verbundglasscheibe als Floatglas oder teilvorgespanntes Glas ausgebildet. Besonders bevorzugt sind die Glasscheiben der Verbundglasscheibe als Einscheibensicherheitsglasscheiben ausgebildet. Ein Verlet zungsrisiko kann mittels der Ausbildung der Glasscheiben als Einscheibensicherheitsglasscheiben minimiert werden. Scharfe Kanten können beim Bruch der Glasscheiben vermieden werden.In particular, the glass panes of the laminated glass pane are designed as float glass or partially toughened glass. The glass panes of the laminated glass pane are particularly preferably designed as single-pane safety glass panes. The risk of injury can be minimized by designing the glass panes as single-pane safety glass panes. Sharp edges can be avoided if the glass panes break.
Des Weiteren kann die Verbundglasscheibe eben oder gekrümmt ausgeführt sein. Grundsätzlich kann die Verbundglasscheibe eine beliebige Außengeometrie oder Umfangsgeometrie aufwei sen. Sie ist daher in vorteilhafter Weise vielfältig einsetz- bar. Die Verbundglasscheibe kann bedarfsgerecht hergestellt werden. Furthermore, the laminated glass pane can be designed to be flat or curved. In principle, the laminated glass pane can have any external geometry or circumferential geometry. It can therefore advantageously be used in a variety of ways. The laminated glass pane can be produced as required.
Alternativ oder zusätzlich ist denkbar, dass ein Airbagsystem oder ein Schlauchsystem entlang der wenigstens einen Bruch spur zwischen den wenigstens zwei Glasscheiben angeordnet ist. Das Airbagsystem oder das Schlauchsystem ist vorzugswei se jeweils dazu vorgesehen, zumindest ein Scheibenteil auto matisiert von dem übrigen Teil der Verbundglasscheibe zu trennen. Auf eine Kraftaufwendung zur Abtrennung eines Schei benteils der zumindest zwei Scheibenteile durch eine Person kann in diesem Fall verzichtet werden. Alternatively or additionally, it is conceivable that an airbag system or a hose system is arranged along the at least one break line between the at least two glass panes. The airbag system or the tube system is preferably provided in each case to automatically separate at least one pane from the remaining part of the laminated glass pane. In this case, there is no need for a person to apply force to separate one part of the disc of the at least two parts of the disc.
Die Reduzierung der Reißfestigkeit ist vorzugsweise als eine mechanische Schwächung der Zwischenschicht ausgebildet. Be sonders bevorzugt ist die mechanische Schwächung als eine Ausnehmung in der Zwischenschicht ausgebildet. Ebenfalls ist denkbar, dass die Reißfestigkeit mittels eines optischen oder chemischen Prozesses reduziert ist. The reduction in tear strength is preferably embodied as a mechanical weakening of the intermediate layer. The mechanical weakening is particularly preferably designed as a recess in the intermediate layer. It is also conceivable that the tear strength is reduced by means of an optical or chemical process.
In einer vorteilhaften Ausgestaltungsvariante ist entlang der wenigstens einen Bruchspur ein Material der Zwischenschicht durch ein Material mit, verglichen mit der Zwischenschicht, reduzierter Reißfestigkeit ersetzt. Hierdurch kann eine be- liebige Reißfestigkeit realisiert werden. Es kann auf eine einfach Art und Weise eine Schwächung der Zwischenschicht ge ring gehalten werden und somit eine Stabilität der Verbund glasscheibe erhöht werden. Eine unerwünschte Beeinträchtigung der Reißfestigkeit entlang der wenigstens einen Bruchspur während eines Prozessschritts des Herstellungsprozesses kann verhindert werden. Beispielsweise kann ein Zusammenschmelzen von Bestandteilen der Zwischenschicht verhindert werden. In an advantageous embodiment variant, a material of the intermediate layer is replaced by a material with, compared to the intermediate layer, reduced tear strength along the at least one breakage track. This can lovable tear resistance can be realized. A weakening of the intermediate layer can be kept ring in a simple manner and thus the stability of the composite glass pane can be increased. An undesirable impairment of the tear strength along the at least one breakage track during a process step of the manufacturing process can be prevented. For example, a melting together of constituents of the intermediate layer can be prevented.
Entlang der Bruchspur weist die Zwischenschicht vorzugsweise eine Reduzierung der Reißfestigkeit gegenüber umliegenden Be reichen der Zwischenschicht von zumindest 60 %, besonders be vorzugt zumindest 80 % und ganz besonders bevorzugt 100 % auf. Hierdurch kann eine Abtrennung des Scheibenteils leicht auch von Personen mit wenig Kraft, kleiner Statur oder klei neren Verletzungen erfolgen. Along the rupture track, the intermediate layer preferably has a reduction in tear strength compared to surrounding areas of the intermediate layer of at least 60%, particularly preferably at least 80% and very particularly preferably 100%. As a result, the disc part can easily be separated even by people with little strength, small stature or smaller injuries.
Unter einem „gebrochenen Zustand der Verbundglasscheibe" ist in diesem Zusammenhang ein Zustand der Verbundglasscheibe zu verstehen, in welchem die wenigstens zwei Glasscheiben einen Splitterbruch aufweisen, der sich wenigstens über die gesamte Bruchspur erstreckt. A “broken state of the laminated glass pane” is to be understood in this context as a state of the laminated glass pane in which the at least two glass panes have a splinter break that extends at least over the entire breakage track.
Des Weiteren wird als eine vorteilhafte Weiterbildung vorge schlagen, dass die zumindest zwei Scheibenteile unabhängig voneinander abtrennbar sind. Jedes der zumindest zwei Schei benteile kann unbeeinflusst von einem Zustand eines anderen der zumindest zwei Scheibenteile als Flucht- und Rettungswege abgetrennt werden. Bei einem erschwerten Zugang zu einem der zumindest zwei Scheibenteile sind die übrigen Scheibenteile der zumindest zwei Scheibenteile für sich allein abtrennbar.Furthermore, it is proposed as an advantageous further development that the at least two pane parts can be separated off independently of one another. Each of the at least two pane parts can be separated as escape and rescue routes without being influenced by a state of another of the at least two pane parts. If access to one of the at least two pane parts is difficult, the remaining pane parts of the at least two pane parts can be separated by themselves.
In einer anderen Weiterbildung wird vorgeschlagen, dass die wenigstens eine Bruchspur einen Bruchspurabschnitt aufweist, entlang dem die zumindest zwei Scheibenteile aneinandergren zen. Auf diese Weise kann eine große zusammenhängende Öffnung geschaffen werden. Des Weiteren kann auf diese Weise eine von der wenigstens einen Bruchspur hervorgerufene Verringerung der Stabilität minimiert werden. In einer vorteilhaften Aus- gestaltungform weist der Bruchspurabschnitt eine Länge von zumindest 10 %, vorzugsweise zumindest 15 % und besonders be vorzugt zumindest 20 % von einer Gesamtlänge der Bruchspur auf. Je größer der gemeinsame Abschnitt, desto geringer ist der erforderliche Kraftaufwand zu einer Abtrennung eines wei teren Scheibenteils der zumindest zwei Scheibenteile. Des Weiteren kann eine Stabilität der Verbundglasscheibe erhöht werden. In einer besonders vorteilhaften Ausgestaltungsform ist die wenigstens eine Bruchspur H-förmig ausgebildet. Dies bietet die Vorteile einer aufwandsgünstigen Herstellung und/oder einer platzsparenden Anordnung der Verbundglasschei be. In another refinement, it is proposed that the at least one breakage track has a breakage track section along which the at least two pane parts border one another. In this way, a large, coherent opening can be created. Furthermore, a reduction in stability caused by the at least one breakage track can be minimized in this way. In an advantageous In the form of a design, the breakage track section has a length of at least 10%, preferably at least 15% and particularly preferably at least 20% of a total length of the breakage track. The larger the common section, the lower the force required to separate a white direct disk part of the at least two disk parts. Furthermore, the stability of the laminated glass pane can be increased. In a particularly advantageous embodiment, the at least one break line is H-shaped. This offers the advantages of an inexpensive production and / or a space-saving arrangement of the laminated glass pane.
In einer vorteilhaften Weiterbildung wird vorgeschlagen, dass die zumindest zwei Scheibenteile in einem gebrochenen Zustand der Verbundglasscheibe werkzeuglos entlang der zumindest ei nen Bruchspur abtrennbar sind. Unter „werkzeuglos abtrennbar" ist zu verstehen, dass die zumindest zwei Scheibenteile je weils von einem Bediener mit einer typischerweise von Hand aufbringbaren Kraft abtrennbar sind, so dass keine zusätzli chen Mittel nötig sind, um das jeweilige Scheibenteil heraus zutrennen. Durch die beschriebene Ausgestaltung kann eine zu verlässige Selbstrettungsmöglichkeit für Einzelpersonen in einer Notsituation geschaffen werden. Nach einer Zerstörung der Scheibe mittels des Initiatorhammers sind somit keine weiteren Mittel zur Abtrennung der zumindest zwei Scheiben teile erforderlich. In an advantageous further development, it is proposed that the at least two pane parts can be separated along the at least one breakage track without tools in a broken state of the laminated glass pane. "Can be separated without tools" means that the at least two pane parts can each be separated by an operator with a force that can typically be applied by hand, so that no additional means are required to separate out the respective pane part a reliable possibility of self-rescue can be created for individuals in an emergency situation.After the pane has been destroyed by means of the initiator hammer, no further means for separating the at least two pane parts are therefore required.
Eine weitere vorteilhafte Weiterbildung schlägt vor, dass we nigstens zwei der zumindest zwei Scheibenteile ungleich große Oberflächen aufweisen. Dies ermöglicht eine asymmetrische Ausführungsform, was in einer jeweiligen Anwendung vorteil haft sein kann. Unter einer „Oberfläche" ist dabei eine Ober fläche eines Scheibenteils der zumindest zwei Scheibenteile in einem unversehrten Zustand des Scheibenteils zu verstehen.A further advantageous development suggests that at least two of the at least two disk parts have surfaces of different sizes. This enables an asymmetrical embodiment, which can be advantageous in a particular application. A “surface” is to be understood as an upper surface of a disk part of the at least two disk parts in an undamaged state of the disk part.
Vorzugsweise ist ein Flächenverhältnis zwischen einer Ober fläche eines kleineren Scheibenteils der zumindest zwei Scheibenteile in einem abgetrennten Zustand und einer Ober- fläche eines größeren Scheibenteils der zumindest zwei Schei benteile in einem abgetrennten Zustand größer als 0,2 und besonders bevorzugt größer als 0,4. Preferably, an area ratio between an upper surface of a smaller pane part of the at least two pane parts in a separated state and a surface Area of a larger disc part of the at least two disc parts in a separated state is greater than 0.2 and particularly preferably greater than 0.4.
In einer vorteilhaften Weiterbildung wird vorgeschlagen, dass jeder der zumindest zwei Scheibenteile derart aus der Ver bundglasscheibe abtrennbar ist, dass dieser mit dem übrigen Teil der Verbundglasscheibe verbunden ist. Durch die be schriebene Weiterbildung kann ein Herunterfallen von Schei benteilen vermieden werden. Es können Verletzungen, insbeson dere in einer Paniksituation, verhindert werden. In an advantageous development it is proposed that each of the at least two pane parts can be separated from the composite glass pane in such a way that it is connected to the remaining part of the composite glass pane. Through the described training, falling of disc parts can be avoided. Injuries, especially in a panic situation, can be prevented.
Ferner wird in einer vorteilhaften Weiterbildung vorgeschla gen, dass jeder der zumindest zwei Scheibenteile beweglich zu dem übrigen Teil der Verbundglasscheibe ist. Durch die be schriebene Weiterbildung kann ein freier Zugang und/oder eine unbehinderte Flucht ermöglicht werden. Es kann ein Gefähr dungspotential und/oder eine Verletzungsgefahr anderer Perso nen verringert werden. Furthermore, it is proposed in an advantageous development that each of the at least two pane parts is movable with respect to the remaining part of the laminated glass pane. The further training described can enable free access and / or unhindered escape. A hazard potential and / or the risk of injury to other people can be reduced.
Vorzugsweise ist ein mit dem übrigen Teil der Verbundglas scheibe verbundenes Scheibenteil der zumindest zwei Scheiben teile werkzeuglos untrennbar mit dem übrigen Teil der Ver bundglasscheibe verbunden. Das mit dem übrigen Teil der Ver bundglasscheibe verbundene Scheibenteil der zumindest zwei Scheibenteile kann demnach nicht ohne Werkzeug vollständig von dem übrigen Teil der Verbundglasscheibe getrennt werden. Hierdurch kann eine Unfallgefahr minimiert werden. Eine Ge fährdung durch ein Herunterfallen oder ein sich lösendes Scheibenteil kann zuverlässig verhindert werden. Des Weiteren sind die zumindest zwei Scheibenteile jeweils relativ zu dem übrigen Teil der Verbundglasscheibe bei gleichzeitiger zuver lässiger Verbindung mit dem übrigen Teil beweglich. Preferably, a pane connected to the remaining part of the laminated glass pane of the at least two panes is inseparably connected to the rest of the composite glass pane without tools. The pane part of the at least two pane parts connected to the remaining part of the laminated glass pane cannot therefore be completely separated from the remaining part of the laminated glass pane without a tool. This can minimize the risk of an accident. A risk of falling down or a part of the pane becoming detached can be reliably prevented. Furthermore, the at least two pane parts are each movable relative to the remaining part of the laminated glass pane with a simultaneous reliable connection to the remaining part.
Als eine weitere vorteilhafte Weiterbildung wird vorgeschla gen, dass die wenigstens eine Bruchspur derart ausgebildet ist, dass eine Überlappung eines jeden Scheibenteils der zu mindest zwei Scheibenteile in einem abgetrennten Zustand mit einem Öffnungsbereich aller übrigen Scheibenteile der zumin- dest zwei Scheibenteile ausgeschlossen ist. Unter einem „Öff nungsbereich eines Scheibenteils" soll dabei ein Bereich der Verbundglasscheibe verstanden werden, durch welchen bei einer Abtrennung des einen Scheibenteils der zumindest zwei Schei benteile eine Öffnung in der Verbundglasscheibe geschaffen werden kann. Demzufolge entspricht der Öffnungsbereich des Scheibenteils einer von dem Scheibenteil hinterlassenen Aus nehmung in der Verbundglasscheibe in einem abgetrennten Zu stand des genannten Scheibenteils. Ein Verschluss oder eine teilweise Verdeckung eines Öffnungsbereichs eines Scheiben teils durch ein anderes Scheibenteil der zumindest zwei Scheibenteile kann auf diese Weise verhindert werden. Es kann ein sicherer Aus- oder Einstieg mittels des Öffnungsbereichs geschaffen werden. Verletzungen einer sich im Öffnungsbereich befindlichen Person durch ein anderes Scheibenteil der zumin dest zwei Scheibenteile kann vermieden werden. As a further advantageous development, it is proposed that the at least one breakage track is designed in such a way that an overlap of each disc part of the at least two disc parts in a separated state with an opening area of all other disc parts of the at least at least two disc parts are excluded. An "opening area of a pane" is to be understood as an area of the laminated glass pane through which an opening can be created in the laminated glass pane when the one pane of the at least two pane parts is separated Recess in the laminated glass pane in a separated state of said pane part. A closure or partial covering of an opening area of a pane part by another pane part of the at least two pane parts can be prevented in this way Injuries to a person located in the opening area by another pane of the at least two pane parts can be avoided.
Vorzugsweise weist ein Scheibenteil der zumindest zwei Schei benteile in einem abgetrennten Zustand einen Abstand zu den Öffnungsbereichen aller übrigen Scheibenteile der zumindest zwei Scheibenteile auf. Eine Verletzungsgefahr durch andere Scheibenteile der zumindest zwei Scheibenteile kann somit weiter verringert werden. A disk part of the at least two disk parts is preferably at a distance from the opening areas of all the other disk parts of the at least two disk parts in a separated state. The risk of injury from other pane parts of the at least two pane parts can thus be further reduced.
Des Weiteren wird vorgeschlagen, dass die erfindungsgemäße Verbundglasscheibe in einem Fenster eines Fahrzeugs verwendet wird. Hierdurch können mit einem Fenster eines Fahrzeugs meh rere Flucht- und Rettungswege bereitgestellt werden. Die Flucht- und Rettungswege können nach Bedarf an eine Innen raumgestaltung des Fahrzeugs angepasst werden. It is also proposed that the laminated glass pane according to the invention be used in a window of a vehicle. As a result, several escape and rescue routes can be provided with one window of a vehicle. The escape and rescue routes can be adapted to the interior of the vehicle as required.
Vorzugsweise ist das Fenster als Isolierglasfenster ausgebil det. Besonders bevorzugt ist wenigstens eine erfindungsgemäße Verbundglasscheibe in Kombination mit einer Einscheibensi cherheitsglasscheibe, einer thermisch vorgespannten Glas scheibe oder zumindest einer weiteren erfindungsgemäßen Ver bundglasscheibe zu einem Isolierglasfenster ausgebildet. Eine thermische Isolation eines Fahrzeuginnenraums kann mit Flucht- und Rettungswegen kombiniert werden. Eine Energieef- fizienz einer Kühlung oder einer Heizung eines Fahrzeuginnen- raums kann mit einer gleichzeitigen Bereitstellung von Flucht- und Rettungswegen erhöht werden. Preferably, the window is designed as an insulating glass window. Particularly preferably, at least one laminated glass pane according to the invention is formed into an insulating glass window in combination with a single pane safety glass pane, a thermally toughened glass pane or at least one further laminated glass pane according to the invention. Thermal insulation of a vehicle interior can be combined with escape and rescue routes. An energy e The efficiency of cooling or heating a vehicle interior can be increased by providing escape and rescue routes at the same time.
In einer vorteilhaften Ausführungsvariante werden die Ver bundglasscheibe auf einer Außenseite und eine Einscheibensi cherheitsglasscheibe auf einer Innenseite des Fensters ver wendet. Durch diese Ausführungsvariante kann eine Wider standsfähigkeit des Fensters gegenüber mechanischen Einflüs sen während eines Fährbetriebs des Fahrzeugs erhöht werden. Eine Bruchgefahr des Fensters im normalen Fährbetrieb kann somit verringert werden. In an advantageous embodiment, the composite glass pane on an outside and a single pane safety glass pane on an inside of the window are used ver. With this variant, a resistance of the window to mechanical influences can be increased during a ferry operation of the vehicle. The risk of the window breaking during normal ferry operations can thus be reduced.
Des Weiteren wird als eine vorteilhafte Weiterbildung vorge schlagen, dass die erfindungsgemäße Verbundglasscheibe in ei nem Fenster eines schienengebundenen Fahrzeugs mit voneinan der abtrennbaren Schlafkapseln verwendet wird. Das Fenster wird hierbei derart angeordnet, dass sich dieses über zumin dest zwei der voneinander abtrennbaren Schlafkapseln er streckt. Das sich über die zumindest zwei voneinander ab trennbaren Schlafkapseln erstreckende Fenster wird vorzugs weise als ein Flucht- und Rettungsweg für die zumindest zwei voneinander abtrennbaren Schlafkapseln verwendet. Das Fahr zeug kann alternativ auch als ein Wasserfahrzeug, ein Luft fahrzeug oder ein anderes Landfahrzeug ausgebildet sein. Un ter einer „Schlafkapsel" soll ein von mehreren, gemeinsam an geordneten Arbeits-, Liege- oder Ruhebereichen abtrennbarer Liege- oder Ruhebereich verstanden werden. Auf die beschrie bene Weise kann für mehrere Schlafkapseln ein gemeinsames Fenster verwendet werden. Hierdurch wird eine Fahrzeugkon struktion vereinfacht. Des Weiteren können Herstellungskosten des Fahrzeugs reduziert werden. Furthermore, it is proposed as an advantageous further development that the laminated glass pane according to the invention is used in a window of a rail-bound vehicle with sleeping capsules which can be separated from one another. The window is arranged in such a way that it extends over at least two of the sleeping capsules that can be separated from one another. The window extending over the at least two separable sleeping capsules is preferably used as an escape and rescue route for the at least two separable sleeping capsules. The vehicle can alternatively be designed as a watercraft, an aircraft or another land vehicle. A "sleeping capsule" should be understood to mean a lying or resting area that can be separated from several working, lying or resting areas arranged together. In the manner described, a common window can be used for several sleeping capsules. This simplifies a vehicle design Furthermore, the manufacturing cost of the vehicle can be reduced.
Vorzugsweise kann die Schlafkapsel von einem Zugabteil oder einem Schlafwagenabteil abgetrennt werden. Besonders bevor zugt sind die Schlafkapseln voneinander separierbar und/oder visuell abtrennbar. Dies erhöht einen Komfort und einen Erho lungswert für Fahrgäste. Ebenfalls kann somit eine Fahrgast zahl erhöht werden. In einer weiteren bevorzugten Ausführungsform werden die we nigstens zwei Schlafkapseln räumlich direkt nebeneinander an geordnet. Über die gemeinsame Fensterscheibe können Fahrgäste unabhängig voneinander aus der jeweiligen Schlafkapsel flie hen oder gerettet werden. The sleeping capsule can preferably be separated from a train compartment or a sleeping car compartment. Particularly before given, the sleeping capsules can be separated from one another and / or visually separated. This increases comfort and relaxation value for passengers. Likewise, a number of passengers can thus be increased. In a further preferred embodiment, the at least two sleeping capsules are spatially arranged directly next to one another. Passengers can escape or be rescued independently of one another via the common window pane.
Eine vorteilhafte Weiterbildung schlägt vor, dass eine erfin dungsgemäße Verbundglasscheibe, welche in der Art weiterge bildet ist, dass diese einen Bruchspurabschnitt aufweist, an welchem die zumindest zwei Scheibenteile aneinandergrenzen, in dem Fahrzeug verwendet wird. Bei dieser Weiterbildung wird der Bruchspurabschnitt im Wesentlichen parallel oder im We sentlichen senkrecht zu einer vorgesehenen Fahrtrichtung des Fahrzeugs ausgerichtet. An advantageous further development proposes that a laminated glass pane according to the invention, which is further developed in such a way that it has a breakage section at which the at least two pane parts adjoin one another, is used in the vehicle. In this development, the broken track section is aligned essentially parallel or essentially perpendicular to an intended direction of travel of the vehicle.
Unter „im Wesentlichen parallel" soll eine Ausrichtung einer Richtung oder Achse relativ zu einer Bezugsrichtung oder Be zugsache verstanden werden, wobei die Richtung oder die Achse gegenüber der Bezugsrichtung oder der Bezugsachse eine Abwei chung von weniger als 8°, vorzugsweise weniger als 5° und be sonders bevorzugt weniger als 2° aufweist. "Essentially parallel" should be understood to mean an alignment of a direction or axis relative to a reference direction or reference matter, the direction or the axis deviating from the reference direction or the reference axis by less than 8 °, preferably less than 5 ° and be particularly preferably less than 2 °.
Unter „im Wesentlichen senkrecht" soll eine Ausrichtung einer Richtung oder Achse relativ zu einer Bezugsrichtung oder Be zugsachse verstanden werden, wobei die Richtung oder die Ach se gegenüber der Bezugsrichtung oder der Bezugsachse einen Winkel einschließt, welcher von 90° eine Abweichung von weni ger als 8°, vorzugsweise weniger als 5° und besonders bevor zugt weniger als 2° aufweist. “Essentially perpendicular” should be understood to mean an alignment of a direction or axis relative to a reference direction or reference axis, the direction or axis enclosing an angle with respect to the reference direction or the reference axis which deviates from 90 ° by less than 8 °, preferably less than 5 ° and particularly preferably less than 2 °.
Durch die beschriebene vorteilhafte Weiterbildung kann die Verbundglasscheibe und somit das Fenster bedarfsgerecht an eine Innenraumgestaltung des Fahrzeugs angepasst werden. Des Weiteren kann durch die beschriebene vorteilhafte Weiterbil dung eine Überlappung eines abgetrennten Scheibenteils der zumindest zwei Scheibenteile in einen Öffnungsbereich anderer Scheibenteile der zumindest zwei Scheibenteile vorteilhaft vermieden werden. Des Weiteren wird ein Fahrzeug vorgeschlagen, welches wenigs tens ein Fenster mit einer erfindungsgemäßen Verbundglas scheibe aufweist. Das Fenster ist hierbei in einer Außenwan dung des Fahrzeugs angeordnet. Das Fenster bietet in einer Notsituation die Möglichkeit an eine raumsparende Innenraum gestaltung angepasste Flucht- und Rettungswege bereit zu stellen. Durch das Fenster kann eine Unfallgefahr bei der Be nutzung des Fensters als Flucht- und Rettungsweg verringert werden. Es können des Weiteren Flucht- und Rettungswege aus voneinander räumlich abgetrennten Innenraumbereichen des Fahrzeugs geschaffen werden. Through the advantageous development described, the laminated glass pane and thus the window can be adapted to an interior design of the vehicle as required. Furthermore, the advantageous development described can advantageously avoid an overlap of a severed pane part of the at least two pane parts in an opening area of other pane parts of the at least two pane parts. Furthermore, a vehicle is proposed which has at least one window with a laminated glass pane according to the invention. The window is arranged in an external wall of the vehicle. In an emergency, the window offers the possibility of providing escape and rescue routes that are adapted to a space-saving interior design. The window can reduce the risk of accidents when using the window as an escape and rescue route. Escape and rescue routes can also be created from interior areas of the vehicle that are spatially separated from one another.
Eine vorteilhafte Weiterbildung schlägt vor, dass das Fahr zeug zumindest zwei Fenster mit einer besonderen Verbundglas scheibe aufweist. Die besondere Verbundglasscheibe ist je weils als erfindungsgemäße Verbundglasscheibe ausgebildet, welche in der Art weitergebildet ist, dass jeder der zumin dest zwei Scheibenteile derart aus der Verbundglasscheibe ab trennbar ist, dass dieser mit dem übrigen Teil der Verbund glasscheibe verbunden ist. Infolge dessen ist jeder der zu mindest zwei Scheibenteile beweglich zu dem übrigen Teil der Verbundglasscheibe. Des Weiteren sind die wenigstens zwei Fenster nebeneinander auf derselben Fahrzeugseite angeordnet. Ferner sind die zumindest zwei Scheibenteile von jeder der besonderen Verbundglasscheiben jeweils mittels einer Halte strecke mit dem übrigen Teil der jeweiligen besonderen Ver bundglasscheibe verbunden. Dabei sind die Haltestrecken der art angeordnet, dass eine Überlappung eines jeden abgetrenn ten Scheibenteils der zumindest zwei Scheibenteile jeder der besonderen Verbundglasscheiben mit einem Öffnungsbereich al ler übrigen Scheibenteile der zumindest zwei Scheibenteile jeder der besonderen Verbundglasscheiben ausgeschlossen ist.An advantageous development suggests that the vehicle has at least two windows with a special laminated glass pane. The special laminated glass pane is designed as a laminated glass pane according to the invention, which is further developed in such a way that each of the at least two pane parts can be separated from the laminated glass pane in such a way that it is connected to the remaining part of the laminated glass pane. As a result, each of the at least two pane parts is movable with respect to the remaining part of the laminated glass pane. Furthermore, the at least two windows are arranged next to one another on the same side of the vehicle. Furthermore, the at least two pane parts of each of the special laminated glass panes are each connected to the remaining part of the respective special laminated glass pane by means of a holding path. The holding sections are arranged in such a way that an overlap of each separated pane part of the at least two pane parts of each of the special laminated glass panes with an opening area of all other pane parts of the at least two pane parts of each of the special laminated glass panes is excluded.
Darunter, dass Fenster nebeneinander angeordnet sind, soll in diesem Zusammenhang verstanden werden, dass zwischen zwei Fenstern kein drittes Fenster angeordnet ist. Unter einer „Haltestrecke" ist eine kürzeste Verbindungslinie in einerThe fact that windows are arranged next to one another should be understood in this context to mean that no third window is arranged between two windows. Under a "stopping line" is a shortest connection line in a
Zwischenschicht der zumindest einen Zwischenschicht zwischen zwei Enden einer ein Scheibenteil der zumindest zwei Schei benteile begrenzenden wenigstens einen Bruchspur zu verste hen. Intermediate layer of the at least one intermediate layer between two ends of a disc part of the at least two disc parts delimiting at least one breakage to understand hen.
Durch die beschriebene vorteilhafte Weiterbildung kann ver mieden werden, dass ein Öffnungsbereich eines Scheibenteils der zumindest zwei Scheibenteile einer Verbundglasscheibe ei nes Fensters von einem Scheibenteil der zumindest zwei Schei benteile einer Verbundglasscheibe eines daneben angeordneten Fensters verdeckt wird. Eine Beschränkung oder Blockierung eines Öffnungsbereichs als Flucht- und Rettungsweg kann ver hindert werden. Des Weiteren kann ein Verletzungsrisiko einer sich im Öffnungsbereich befindlichen Person durch Scheiben teile anderer Fenster minimiert werden. The advantageous development described avoids that an opening area of a pane of the at least two pane parts of a laminated glass pane of a window is covered by a pane of the at least two panes of a laminated glass pane of a window arranged next to it. A restriction or blocking of an opening area as an escape and rescue route can be prevented. Furthermore, the risk of injury to a person in the opening area due to pane parts from other windows can be minimized.
Bevorzugt bilden die Haltestrecke und die wenigstens eine Bruchspur eine geschlossene Strecke, welche einen Umfang ei nes Scheibenteils der zumindest zwei Scheibenteile begrenzt. Besonders bevorzugt grenzt die aus der Haltestrecke und der Bruchspur gebildete geschlossene Strecke ein Scheibenteil der zumindest zwei Scheibenteile gegenüber dem übrigen Teil der Verbundglasscheibe ab. Hierdurch kann sichergestellt werden, dass jedes Scheibenteil der zumindest zwei Scheibenteile die für einen Flucht- und Rettungsweg erforderlichen Mindestmaße erfüllen kann. The holding section and the at least one breakage track preferably form a closed section which delimits a circumference of a disk part of the at least two disk parts. Particularly preferably, the closed section formed from the holding section and the break line delimits a pane part of the at least two pane parts from the remaining part of the laminated glass pane. This can ensure that each pane of the at least two pane parts can meet the minimum dimensions required for an escape and rescue route.
Des Weiteren schlägt eine vorteilhafte Weiterbildung vor, dass zumindest eine der Haltestrecken quer zu einer vorgese henen Fahrtrichtung des Fahrzeugs angeordnet ist. In anderen Worten ist die zumindest eine Haltestrecke entlang einer Richtung, welche relativ zu einer Fahrtrichtung einen Winkel von ungleich 0° aufweist, ausgerichtet. Auf diese Weise kann ein einfacher Zugang von außen zu einem schwer zugänglichen oder höher gelegenen Bereich des Fahrzeugs, wie beispielswei se ein zweites Obergeschoss des Fahrzeugs, durch seitliches herausklappen der Scheibenteile geschaffen werden. Bevorzugt ist die zumindest eine Haltestrecke in einer Richtung im We sentlichen senkrecht zu einer vorgesehenen Fahrtrichtung aus gerichtet. In einer bewährten Ausführungsform ist das Fahrzeug als ein Schlafwaggon mit Schlafabteilen ausgebildet. Es können ein zelne Flucht- und Rettungswege bei einer raumsparenden Innen raumgestaltung bereitgestellt werden. Bei nebeneinander ange ordneten Schlafkapseln mit einer gemeinsamen Fensterscheibe können eine Vielzahl an Flucht- und Rettungsmöglichkeiten aus einem Schlafabteil geschaffen werden. Auf diese Weise steht aus jeder Schlafkapsel ein eigener Flucht- und Rettungsweg zur Verfügung, welcher unabhängig von einem Zugang zu anderen Schlafkapseln genutzt werden kann. Ist beispielsweise ein Zu gang zu einer Schlafkapsel verschlossen oder blockiert sind die anderen Flucht- und Rettungswege unabhängig davon nutz bar. Furthermore, an advantageous development suggests that at least one of the stopping sections is arranged transversely to a predetermined direction of travel of the vehicle. In other words, the at least one stopping section is aligned along a direction which, relative to a direction of travel, has an angle not equal to 0 °. In this way, easy access from the outside to an area of the vehicle that is difficult to access or located higher up, such as a second upper floor of the vehicle, can be created by folding out the window parts to the side. The at least one stopping section is preferably directed in a direction essentially perpendicular to an intended direction of travel. In a proven embodiment, the vehicle is designed as a sleeping car with sleeping compartments. Individual escape and rescue routes can be provided with a space-saving interior design. When sleeping capsules are arranged side by side with a common window pane, a variety of escape and rescue options can be created from a sleeping compartment. In this way, each sleeping capsule has its own escape and rescue route, which can be used independently of access to other sleeping capsules. If, for example, access to a sleeping capsule is closed or blocked, the other escape and rescue routes can be used regardless of this.

In an assembled state of the window 12 in the outer wall 14 of the vehicle 10, the single pane safety glass pane 22 is arranged in the direction of the sleeping compartment. The laminated glass pane 24 is arranged in the direction of an outer environment of the vehicle 10 starting from the sleeping compartment. The laminated glass pane 24 has two glass panes 26, 28 which are connected to the miteinan by means of an intermediate layer 30. Furthermore, the laminated glass pane 24 has a breakage track 32, along which a tear strength of the intermediate layer 30 is reduced in relation to the surrounding areas of the intermediate layer 30. The breaking trace 32 is designed as a recess in the intermediate layer 30.
FIG 4 zeigt eine flächige Ansicht der Verbundglasscheibe 24 mit der Bruchspur 32, entlang derer zwei Scheibenteile 34, 36 von einem übrigen Teil 38 der Verbundglasscheibe 24 abtrenn bar sind. In einem gebrochenen Zustand der Verbundglasscheibe 24 sind die zwei Scheibenteile 34, 36 werkzeuglos entlang der Bruchspur 32 abtrennbar. Die Bruchspur 32 ist offen ausgebil det. Des Weiteren weist die Bruchspur 32 einen Bruchspurab schnitt 40 auf, entlang dem die zwei Scheibenteile 34, 36 an einander grenzen. Die zwei Scheibenteile 34, 36 sind jeweils unabhängig voneinander entlang der Bruchspur 32 von dem übri gen Teil 38 der Verbundglasscheibe 24 abtrennbar. Die Bruch spur 32 ist H-förmig ausgebildet. Die Bruchspur 32 weist vier Enden 42, 44 auf. In einem abgetrennten Zustand der zwei Scheibenteile 34, 36 ist jedes der zwei Scheibenteile mittels jeweils einer Haltestrecke 46 mit dem übrigen Teil 38 der Verbundglasscheibe 24 verbunden. Die jeweilige Haltestrecke 46 erstreckt sich als eine kürzeste Verbindungslinie zwischen jeweils zwei der Enden 42, 44 der Bruchspur 32. Die Bruchspur 32 bildet mit jeweils einer Haltestrecke 46 jeweils eine ge schlossene Strecke um jeweils eines der zwei Scheibenteile 34, 36. Jeweils eine der geschlossenen Strecken grenzt je weils eines der zwei Scheibenteile 34, 36 von dem übrigen Teil 38 der Verbundglasscheibe 24 ab. Die zwei Scheibenteile 34, 36 sind gegenüber dem übrigen Teil 38 der Verbundglas- scheibe 24 um die Haltestrecke 46 beweglich. Des Weiteren sind die jeweiligen Haltestrecken 46 parallel zueinander und zu dem gemeinsamen Bruchspurabschnitt 40 angeordnet. Eine Überlappung eines jeden abgetrennten Scheibenteils 34, 36 mit einem Öffnungsbereich 48 des übrigen Scheibenteils 36, 34 ist somit ausgeschlossen. FIG. 4 shows a planar view of the laminated glass pane 24 with the break trace 32, along which two pane parts 34, 36 can be separated from a remaining part 38 of the laminated glass pane 24. In a broken state of the laminated glass pane 24, the two pane parts 34, 36 can be separated along the breakage track 32 without tools. The breaking trace 32 is open ausgebil det. Furthermore, the breakage track 32 has a breakage track section 40, along which the two disc parts 34, 36 adjoin one another. The two pane parts 34, 36 can each be separated from the rest of the part 38 of the laminated glass pane 24 independently of one another along the break line 32. The break lane 32 is H-shaped. The breaking trace 32 has four ends 42, 44. In a separated state of the two pane parts 34, 36, each of the two pane parts is connected to the remaining part 38 of the laminated glass pane 24 by means of a respective holding section 46. The respective holding section 46 extends as a shortest connecting line between each two of the ends 42, 44 of the breakage track 32. The breakage track 32 forms with a holding track 46 in each case a closed track around one of the two disc parts 34, 36 Stretch delimits one of the two pane parts 34, 36 from the remaining part 38 of the laminated glass pane 24. The two pane parts 34, 36 are opposite the remaining part 38 of the laminated glass disk 24 to the holding distance 46 movable. Furthermore, the respective holding sections 46 are arranged parallel to one another and to the common fracture track section 40. An overlap of each separated disk part 34, 36 with an opening area 48 of the remaining disk part 36, 34 is therefore ruled out.
Die eben beschriebene Verbundglasscheibe 24 wird in den meh reren als Isolierglasfenster ausgebildeten Fenstern 12 des Fahrzeugs 10, wie in FIG 1 dargestellt, verwendet. Zum Teil ist der gemeinsame Bruchspurabschnitt 40 der jeweiligen Ver bundglasscheibe 24 eines der mehreren Fenster 12 parallel o- der senkrecht zu einer vorgesehenen Fahrtrichtung 50 des Fahrzeugs 10 ausgerichtet. Ebenso sind je nach Ausrichtung eines Fensters 12 der mehreren Fenster 12 in der Außenwand die Haltestrecken 46 der jeweiligen Verbundglasscheiben 24 parallel oder senkrecht zu der Fahrtrichtung 50 ausgerichtet.The laminated glass pane 24 just described is used in the several windows 12 of the vehicle 10, which are designed as insulating glass windows, as shown in FIG. In part, the common fracture track section 40 of the respective composite glass pane 24 of one of the multiple windows 12 is aligned parallel or perpendicular to an intended direction of travel 50 of the vehicle 10. Likewise, depending on the orientation of a window 12 of the plurality of windows 12 in the outer wall, the holding sections 46 of the respective laminated glass panes 24 are oriented parallel or perpendicular to the direction of travel 50.
Im folgenden Abschnitt wird der Übersichtlichkeit halber ein Fenster 12 mit der erfindungsgemäßen Verbundglasscheibe 24 der mehreren in der Außenwand angeordneten Fenster 12 und de ren Anordnung, beispielhaft für die übrigen Fenster 12 mit der erfindungsgemäßen Verbundglasscheibe 24, näher beschrie ben. Das Fenster 12 erstreckt sich über die zwei voneinander abtrennbaren Schlafkapseln 16, 18. Des Weiteren kann dasIn the following section, for the sake of clarity, a window 12 with the laminated glass pane 24 according to the invention of the multiple windows 12 arranged in the outer wall and de ren arrangement, for example for the remaining windows 12 with the laminated glass pane 24 according to the invention, are described in more detail. The window 12 extends over the two sleeping capsules 16, 18 which can be separated from one another
Fenster 12 als ein Flucht- und Rettungsweg für die zwei von einander abtrennbaren Schlafkapseln 16, 18 verwendet werden.Window 12 can be used as an escape and rescue route for the two sleeping capsules 16, 18 which can be separated from one another.
In einem Notfall kann das Fenster 12 aus dem Fahrzeuginnen- raum heraus geöffnet werden. Damit zumindest ein Scheibenteil der zwei Scheibenteile 34, 36 aus der Verbundglasscheibe 24 abtrennbar ist, muss die Verbundglasscheibe 24 gebrochen wer den. Hierzu kann aus einem Fahrzeuginnenraum beispielsweise mittels eines nicht näher dargestellten Initiatorhammers zu erst die Einscheibensicherheitsglasscheibe 22 zerstört wer den. In einem nächsten Schritt kann dann, beispielsweise mit tels des Initiatorhammers, die Verbundglasscheibe 24 einge schlagen werden. In einem gebrochenen Zustand der Verbund glasscheibe können die zwei Scheibenteile 34, 36 unabhängig voneinander von dem übrigen Teil 38 der Verbundglasscheibe 24 werkzeuglos abgetrennt werden. Beispielsweise kann eine Per son von Hand zumindest ein Scheibenteil der zwei Scheibentei le 34, 36 von dem übrigen Teil 38 der Verbundglasscheibe 24 abtrennen. Hierdurch kann jeweils ein Fluchtweg von innen aus den einzelnen Schlafkapseln 16, 18 geschaffen werden. Alter nativ können die zwei Scheibenteile 34, 36 unabhängig vonei nander von außen von dem übrigen Teil 38 der Verbundglas scheibe 24 abgetrennt werden. Hierdurch kann ein Rettungsweg jeweils zu den einzelnen Schlafkapseln 16, 18 von außen ge schaffen werden. In an emergency, the window 12 can be opened from inside the vehicle. So that at least one pane of the two pane parts 34, 36 can be separated from the laminated glass pane 24, the laminated glass pane 24 must be broken. For this purpose, the single-pane safety glass pane 22 can first be destroyed from a vehicle interior, for example by means of an initiator hammer (not shown in detail). In a next step, the laminated glass pane 24 can then be hit, for example by means of the initiator hammer. In a broken state of the laminated glass pane, the two pane parts 34, 36 can be independent are separated from each other from the remaining part 38 of the laminated glass pane 24 without tools. For example, a person can manually separate at least one pane of the two Scheibentei le 34, 36 from the remaining part 38 of the laminated glass pane 24. In this way, an escape route can be created from the inside of the individual sleeping capsules 16, 18. Alternatively, the two pane parts 34, 36 can be separated from the remaining part 38 of the laminated glass pane 24 independently of one another. In this way, an escape route to the individual sleeping capsules 16, 18 can be created from the outside.
Bei zwei nebeneinander auf derselben Fahrzeugseite angeordne ten Fenstern 12 sind die jeweils zwei Haltestrecken 46 der zwei Verbundglasscheiben 24 derart angeordnet, dass eine Überlappung eines jeden von den zwei Verbundglasscheiben 24 abgetrennten Scheibenteils 34, 36 mit einem Öffnungsbereich 48 aller übriger Scheibenteile 34, 36 der zwei Verbundglas scheiben 24 ausgeschlossen ist. Dies wird realisiert, indem ein jedes Scheibenteil 34, 36 in dem abgetrennten Zustand im mer einen Abstand zu einem Öffnungsbereich 48 aller anderen Scheibenteile 34, 36 der Verbundglasscheiben 24 aller neben einander auf derselben Fahrzeugseite angeordneten Fenstern 12 aufweist. In the case of two windows 12 arranged next to one another on the same side of the vehicle, the two holding sections 46 of the two laminated glass panes 24 are arranged in such a way that an overlap of each pane 34, 36 separated from the two laminated glass panes 24 with an opening area 48 of all other pane parts 34, 36 of the two Laminated glass panes 24 is excluded. This is realized in that each pane 34, 36 in the separated state is always at a distance from an opening area 48 of all other pane parts 34, 36 of the laminated glass panes 24 of all windows 12 arranged next to one another on the same side of the vehicle.
Obwohl die Erfindung im Detail durch das bevorzugte Ausfüh rungsbeispiel näher illustriert und beschrieben wurde, so ist die Erfindung nicht durch das offenbarte Beispiel einge schränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den Schutzumfang der Erfindung zu verlassen. Although the invention has been illustrated and described in more detail by the preferred exemplary embodiment, the invention is not restricted by the disclosed example and other variations can be derived therefrom by the person skilled in the art without departing from the scope of protection of the invention.
