[0002] For example, there may be specific requirements for fixing window panes in door panels of rail vehicles. Traditionally, a window pane is fixed in a rail vehicle window using adhesive or simply a rubber profile. However, the use of a different adhesive, perhaps one with a shorter curing time, would also be conceivable.

[0003] DE 10 2013 204 992 A1 relates to a fixing device for fixing a window pane of a window in a door leaf for a vehicle, wherein the fixing device comprises a profile element, a window profile element and a fastening device, wherein the fastening device is designed to fasten the profile element and the window profile element to each other by positive locking and / or force locking, wherein the profile element is formed from an elastic material, wherein the profile element has a recessed section for gripping an edge area of ​​the window pane, an attachment section for attaching a part of the fastening device to the profile element by positive locking and a cover section for covering the fastening device.

[0004] Against this background, the object of the present invention is to provide an improved fixing device for fixing a window pane of a window in a door leaf for a rail vehicle, an improved window for a rail vehicle and an improved method for fixing a window pane of a window in a door leaf for a rail vehicle by means of such a fixing device.

[0005] This problem is solved by a fixing device for fixing a window pane of a window in a door leaf for a rail vehicle, by a window for a rail vehicle and by a method for fixing a window pane of a window in a door leaf for a rail vehicle by means of such a fixing device according to the main claims.

[0006] According to embodiments, a window pane can be fixed in a door leaf for a rail vehicle within a profile element, for example, a rubber profile, by a fastening device, such as at least one screw. In other words, window pane mounting or fixing can be implemented, in particular, by applying common processes to replace special processes, such as gluing, or to replace disadvantageous methods. Such mounting or fixing of window panes in door leaves for rail vehicles can also enable implementation in series production. Thus, according to embodiments, fixing a window pane in a door leaf for a rail vehicle can, for example, eliminate the need for adhesives or other bonding agents, and therefore for material-bonded connections.In this case, the fastening device, such as at least one fixing screw, can be covered by a profile element, in particular a fixing rubber profile, of the fixing device itself and thus be invisible to passengers of the rail vehicle.

[0007] Advantageously, according to embodiments, assembly time can be reduced, vandalism protection improved, and the window pane can be quickly replaced directly in the rail vehicle. Compared to fixing by fabric bonding, such adhesive-free fixing of the window pane, or fixing without fabric bonding according to embodiments, can, for example, also advantageously eliminate the need for certification of the bonding process for rail transport and the curing time for the adhesive, thus enabling quick and easy replacement of the window pane directly in the rail vehicle. Compared to fixing solely by a rubber profile, a combined fixing according to embodiments can, in particular, result in a flat or...A level surface is obtained, avoiding the protrusion of a rubber profile from the mounting surface, and enabling the window pane to be replaced directly in the rail vehicle.

[0008] A fixing device for fixing a window pane of a window in a door leaf for a rail vehicle is presented, wherein the fixing device comprises a profile element, a window profile element and a fastening device, wherein the fastening device is designed to fasten the profile element and the window profile element to each other by positive locking and additionally or alternatively by frictional locking, wherein the profile element is formed from an elastic material, wherein the profile element has a recessed section for gripping an edge region of the window pane, an attachment section for attaching a part of the fastening device to the profile element by positive locking, a cover section for covering the fastening device and a connecting section for connecting the cover section to the window profile element by positive locking.wherein the cover section is arranged between the mounting section and the connecting section, wherein the window profile element has an arrangement section for arranging a further part of the fastening device and a receiving section for receiving the connecting section of the profile element.

[0009] The profile element can also be referred to as a fixing profile or fixing rubber profile. The window profile element can also be referred to as a window profile. The gripping can represent a connection by positive locking. The arranging can represent a connection by positive locking. The cover section and the connecting section of the profile element can be bent relative to the recess section and the mounting section of the profile element to allow access to the fastening device. The recess section, the mounting section, and the cover section of the profile element can extend along and additionally or alternatively parallel to a principal extension plane of the window pane.

Such an embodiment offers the advantage that the profile element and the window profile element can be fastened to each other in a robust, reliable, and easily detachable manner by positive locking and, additionally or alternatively, by frictional locking.

[0012] Furthermore, when the profile element and the window profile element are joined together, the cover section of the profile element can be aligned flush with a cover section of the window profile element. The cover section can be located adjacent to the receiving section. The receiving section can also be positioned between the cover section and the mounting section. Advantageously, when the profile element and the window profile element are joined together, the cover section and a cover section of the window profile element can form a plane or flush surface if the connecting section is received within the receiving section.

[0013] Furthermore, the window profile element can have an outer contact section for abutting an outer sheet of a wall of the door leaf surrounding the window for the rail vehicle, and an inner contact section for abutting an inner sheet of the wall of the door leaf surrounding the window for the rail vehicle. The contact sections can be arranged on opposite sides of the window profile element. The outer sheet can face the surroundings of the rail vehicle. The inner sheet can face an interior or passenger area of ​​the rail vehicle.
