Description

The invention relates to a vehicle interior ceiling for delimiting an interior of a vehicle at the top according to the preamble of claim 1, and a lighting system for a vehicle comprising the vehicle interior ceiling.

Such a vehicle ceiling is, for example, from DE 10 2013 212454 B3 known. Further embodiments of vehicle interior covers result from the WO 2004/101342 A1 and the DE 10 2008 039122 A1 .

A vehicle interior ceiling is usually provided in a vehicle in order to delimit an interior space of the vehicle at the top. A lighting unit is often integrated into the ceiling of the vehicle interior in order to enable the interior to be illuminated.

In vehicles for passenger transport, in particular in rail vehicles, a vehicle interior ceiling is usually provided, which is made up of flat or curved ceiling panels. The vehicle interior ceiling in the rail vehicle also has lighting fields, which are often arranged in a row. The row of lighting fields usually runs in the longitudinal direction of the rail vehicle. The lighting fields can, for example, have fluorescent tubes as light sources.

However, such lighting creates little comfort for the passengers.

An object of the invention is therefore to provide a vehicle ceiling with lighting means by which a pleasant lighting for the passenger can be created.

The object is achieved by a vehicle interior ceiling for delimiting an interior of a vehicle at the top with a plurality of light strips for illuminating the interior of the vehicle and/or for displaying information for a passenger in the interior of the vehicle, a large number of webs running in the longitudinal direction of the vehicle interior ceiling, which are spaced apart from one another, with channel-shaped depressions running in the longitudinal direction of the vehicle interior ceiling being formed in the spaces between the webs, and the multiple light bands being arranged at least in several of the spaces and/or at least on several of the webs and running in the longitudinal direction of the vehicle interior ceiling, the vehicle ceiling has a plurality of profile elements, and wherein each of the profile elements has in each case at least a part of one of the webs and a connecting element for connecting adjacent webs, and the profile elements can be displaced in relation to one another in their transverse direction.

The vehicle ceiling is expediently set up for installation in a vehicle. In particular, the vehicle ceiling can be installed in a vehicle for passenger transport, in particular in a rail vehicle.

The vehicle ceiling according to the invention has the advantage that the light bands can be distributed over the vehicle interior ceiling. In this way, lighting that is pleasant, particularly for passengers, can be achieved. In particular, brightness can be kept constant and/or evenly distributed over a large spatial area.

Another advantage is that only part of the light strips can be switched on. In this way, brightness can be regulated. Preferably, there are no large differences in brightness within the illuminated space when only some of the light strips are switched on.

The vehicle ceiling also opens up a wide range of options for specifically controlling the lighting, especially the light strips here.

It is expedient if the light strips each comprise a plurality of luminous elements. The luminous bodies of the light strips can preferably be controlled individually. Furthermore, it is advantageous if the lighting elements of the light bands can be controlled in groups.

For example, the lighting elements of the light strips can be switched on and/or off individually and/or in groups.

If, for example, only part of the lighting elements are switched on at any given time, the service life of the lighting strips can increase significantly.

Furthermore, the light intensity of the luminous bodies of the light bands can be controllable individually and/or in groups.

In this way, the light intensity of the light strips can be adjusted to a particular time of day. Furthermore, the light intensity of at least some of the luminous elements can be increased and/or reduced, in particular in a spatially limited manner. In this way, the light intensity of the lamps can be adjusted to spatial conditions. For example, different zones in the interior can be illuminated with different brightness in this way. In particular, in this way a brightness perceptible by a passenger—particularly limited in space—can be controlled.

In addition, a light color of the illuminants of the light strips can be controlled individually and/or in groups. In this way, information can be conveyed to a viewer, in particular a passenger. In addition, the light color can be adjusted to the time of day.

The light color of a luminous body can be described by means of a wavelength range emitted by the luminous body. Furthermore, the light color of a luminous body can be described by means of a color temperature. The light color of a luminous element can preferably be controlled by controlling the wavelength range emitted by the luminous element and/or the color temperature.

For example, several lighting elements of a single light band can form a common group. In particular, all the luminous bodies of a single light band can form a common group. Furthermore, a light strip can be subdivided into several segments, with the luminous bodies of a respective segment forming a group. Furthermore, a number of luminous bodies from a number of light strips can form a common group. For example, several luminous bodies of several segments of several light bands can form a common group.

The luminous bodies of a group can be arranged adjacent to one another, for example. Furthermore, other luminous elements which do not belong to the group can be arranged between the luminous elements of a group. In addition, the luminous bodies of a group can be arranged in a predetermined pattern.

It is preferred if the luminous bodies are in the form of LEDs (light-emitting diodes, in particular inorganic). Furthermore, the luminous bodies can be in the form of OLEDs (organic light-emitting diodes).

The LEDs can be single color LEDs. Furthermore, the LEDs can be multicolor LEDs, for example RGB LEDs.

In principle, it is possible for other luminous bodies to be used. For example, a luminous element can also be a segment of a luminous foil.

According to the invention, the vehicle interior ceiling has a multiplicity of webs, in particular running in the longitudinal direction of the vehicle interior ceiling. The webs are spaced apart. Channel-shaped depressions running in particular in the longitudinal direction of the vehicle interior ceiling are formed in the intermediate spaces between the webs.

This means that the webs and the spaces are preferably arranged alternately.

The several light bands are arranged at least in several of the intermediate spaces and/or at least on several of the webs. It is also expedient if the light bands run in the longitudinal direction of the vehicle interior ceiling.

Direct and/or indirect lighting can be provided by means of the vehicle ceiling.

The depth of the deepening is expediently limited. In other words: it is expediently provided that the webs are not separated from one another solely by a recess. In contrast, it is expediently provided that the webs are each connected, for example, by one or more connecting element(s). The connecting elements preferably delimit the depth of the depressions. In other words, the depressions are preferably limited in depth by one or more connecting element(s). It makes sense for the vehicle ceiling to include the connecting elements.

The respective channel-shaped depression in a respective intermediate space is/is preferably delimited laterally in each case by respective adjacent webs. It is also advantageous if the depth of the respective channel-shaped depression in a respective intermediate space is limited by one or more respective connecting element(s) which connect(s) the adjacent webs to one another. The latter one or more connecting element(s) may be the aforementioned connector(s). Preferably, the respective channel-shaped depression in a respective intermediate space is limited in height by a respective opening of the respective intermediate space.

In particular, the opening of the intermediate space can be opposite the one or more connecting element(s). Furthermore, in particular the depth of the depression can be limited by the one or more connecting element(s) and on the opposite side by the opening of the intermediate space.

It is preferred if the light strips each have a plurality of luminous bodies with a respective light exit direction. The latter luminous elements can be the aforementioned luminous elements. The light exit direction can be a central light exit direction, for example. Furthermore, the light exit direction can include a range of directions.

The light exit directions of at least some of those light bands which are each arranged in one of the intermediate spaces preferably point in each case at least essentially to the opening of that intermediate space in which the respective light band is arranged.

In this way direct illumination can be provided.

In particular, when the vehicle ceiling is mounted in a vehicle, an interior of the vehicle can be directly illuminated in this way.

Furthermore, a reflector can be arranged in at least one intermediate space in which a light band is arranged. The light emission directions of the light band that is arranged in the latter intermediate space, preferably point at least substantially towards the reflector. The reflector is preferably set up to deflect the light exit direction. The deflected light exit direction preferably points at least essentially to the opening of that intermediate space in which the respective light strip is arranged.

Indirect lighting can be provided in this way.

In particular, when the vehicle ceiling is mounted in a vehicle, an interior of the vehicle can be indirectly illuminated in this way.

The vehicle interior ceiling can have at least one profile plate. It is advantageous if at least one profile plate has the aforementioned webs and the aforementioned intermediate spaces. The webs of the profile plate are expediently connected to one another firmly, in particular immovably, via the aforementioned connecting elements. In particular, the profile plate can be designed as a profile sheet. For example, the profile plate can be used as a web plate, a prismatic plate, a trapezoidal plate, in particular as a trapezoidal sheet metal, or the like. be trained. The profile plate is expediently designed in one piece.

A web preferably comprises two web sides and a web front connecting the web sides. The web sides can be at right angles to the web front. Furthermore, the web sides can be at an obtuse angle to the web front. In principle, the web sides can also be at an acute angle to the web front.

According to the invention, the vehicle interior cover comprises a number of profile elements.

It is provided that each of the profile elements has at least part of one of the webs. For example, each of the profile elements can comprise at least one web side and at least a part of the web front.

It is further provided that each of the profile elements has a connecting element for connecting adjacent webs. The connecting element can be the previously mentioned connecting element or one of the previously mentioned connecting elements. The respective connecting element preferably delimits a respective recess in terms of depth.

It is advantageous if the part of the web and the connecting element each run in the longitudinal direction of the respective profile element. The connecting element can be aligned parallel to the at least one part of the web front.

In addition, the profile elements are mutually displaceable in their transverse direction. For example, the profile elements can be displaced in relation to one another in their transverse direction between a pushed-together state and a pulled-apart state.

In particular, the profile elements can be brought from the pulled-apart state into the pushed-together state by moving them. Furthermore, the profile elements can be brought from the pushed-together state into the pulled-apart state by moving them.

For example, the profile elements can be slidably attached to a carrier of the vehicle ceiling.

Furthermore, the profile elements can be at least partially overlapped. It is advantageous if the profile elements at least partially overlap one another when pushed together.

The width of the vehicle interior ceiling can be adjusted by means of the displaceability of the profile elements relative to one another. For example, installation tolerances can be compensated for by means of the displaceability of the profile elements during assembly of the vehicle interior ceiling.

When the vehicle interior ceiling is mounted in a vehicle, the accessibility of components above the vehicle interior ceiling can be ensured by means of the displaceability of the profile elements relative to one another. In this way, separate ceiling flaps can be dispensed with.

The several profile elements of the vehicle interior cover are expediently similar to one another, in particular at least essentially identical. In this way, tool costs and thus also the manufacturing costs incurred can be reduced.

The vehicle ceiling can have a locking mechanism. The locking mechanism can, in particular in the locked state, prevent the profile elements from being pushed together. In this way, unauthorized pushing together of the profile elements can be prevented. Unauthorized access to components above the vehicle interior ceiling can thus be prevented.

At least one of the profile elements can have a web front which, when the profile elements are pushed together, at least partially, in particular completely, covers the depression of an adjacent profile element. Furthermore, the last-mentioned web front can release the recess of the adjacent profile element when the profile elements are in a pulled-apart state. Several of the profile elements, in particular all profile elements, can have such a web front.

If one of the light bands is arranged in the space which forms the depression of the adjacent profile element is covered and thus protected when the profile elements are pushed together. In this way, contamination and/or damage to the light strip during maintenance work above the vehicle interior ceiling can be avoided.

For example, each of the profile elements can have a U-profile and a tab. The channel may have two flanges each with a lower end and an upper end and a base connecting the lower ends of the flanges. In addition, the tab can be arranged at the upper end of one of the flanges of the U-profile.

The tab can form the web front mentioned above. Furthermore, the flanges of the U-profile can each form web sides of adjacent webs. In addition, the base of the U-profile can form the aforementioned connecting element.

In this way, the U-profile can have/form the indentation.

In particular, the tab can cover at least one of the profile elements in a pushed-together state of the profile elements, the depression of the U-profile of an adjacent profile element.

The vehicle ceiling can also have perforations. Air can flow through the perforations. In this way, the light strips can be cooled. This can increase the service life of the light strips. In addition, the air flowing through the perforation can be used for air conditioning, in particular for cooling, of a vehicle interior, in particular a passenger compartment.

Furthermore, the invention is aimed at a lighting system for a vehicle with the aforementioned vehicle interior ceiling and/or one of its developments and with a control unit, which is set up to control lighting elements of the light strips individually and/or in groups.

The luminous bodies are preferably the aforementioned luminous bodies.

In particular, the control unit can be set up to switch the luminous bodies on and/or off individually and/or in groups.

Furthermore, the control unit can be set up to set a light intensity of the luminous bodies individually and/or in groups. Furthermore, the control unit can be set up to set a light color of the luminous bodies individually and/or in groups.

The invention is also aimed at a vehicle for passenger transport with an interior, the aforementioned vehicle interior ceiling and/or the aforementioned lighting system and/or a respective development.

The vehicle for passenger transport, also referred to below as vehicle for short, can in particular be a rail vehicle.

The interior of the vehicle is expediently at least partially delimited at the top by the vehicle interior ceiling.

The longitudinal direction of the vehicle interior ceiling preferably corresponds to a longitudinal direction of the vehicle. In particular, the webs and the spaces in the vehicle interior ceiling can be aligned in the longitudinal direction of the rail vehicle.

The vehicle ceiling can also have perforations. Air can flow into the interior of the vehicle through the perforations in the vehicle interior ceiling. A relaxation space for conditioned air can be arranged in the vehicle above the vehicle interior ceiling. The conditioned air can pass from the relaxation space through the perforations into the interior of the vehicle. In this way, the conditioned air can gently trickle into the interior of the vehicle. A disturbing draft in the interior of the vehicle can be avoided in this way. Furthermore, cooling of the light bands can be achieved in this way. This can increase the service life of the light strips.

Furthermore, the invention is aimed at using the aforementioned vehicle interior ceiling and/or the aforementioned lighting system and/or a respective development for illuminating an interior of a vehicle, in particular a rail vehicle. The interior is expediently at least partially delimited at the top by the ceiling of the vehicle interior.

The vehicle is preferably the aforementioned vehicle, in particular the aforementioned vehicle for passenger transport.

Different zones in the interior are preferably illuminated with different levels of brightness using the light strips.

The invention is also aimed at using the aforementioned vehicle interior ceiling and/or the aforementioned lighting system and/or a respective development for displaying information for a passenger inside a vehicle, in particular inside a rail vehicle.

In this way, the information displayed can be visible to all passengers in particular, regardless of how many passengers are in the vehicle. This is an advantage over displays in the floor area, which can be covered by passengers.

The vehicle is preferably the aforementioned vehicle, in particular the aforementioned vehicle for passenger transport.

The light bands and/or their segments can indicate passenger seat occupancy in the interior of the vehicle, in particular in terms of color.

In other words: the light bands of the vehicle interior ceiling can be set up to indicate passenger space occupancy in an interior of a rail vehicle.

A seat and/or standing space for a passenger in the vehicle can preferably be understood as a passenger space.

The passenger seat occupancy can be displayed by car, by compartment and/or by seat.

Furthermore, the lighting elements of the light bands can generate an arrow-shaped light image as a direction indicator for guiding a passenger.

The photograph can be a still photograph. Furthermore, the light image can be a running light image. In the case of a running light image, the arrow-shaped light image can move in the direction of the arrow, for example. In this way, the running light image can draw increased attention from the passengers.

For example, the light image can indicate a direction that is advantageous for a passenger. For example, the light image may indicate a direction to an adjacent emptier carriage section.

In an emergency, for example, a vehicle control unit of the vehicle can initiate the arrow-shaped light image, which then preferably indicates the shortest route to the next exit.

The information displayed can affect a flow of passengers within the vehicle—in particular positively. In particular, the information displayed can be used to direct the flow of passengers within the vehicle. In this way, for example, passenger changeover times can be optimized or shortened.

In this way, the aforementioned vehicle interior ceiling and/or the aforementioned lighting system and/or a respective development can be used as a passenger guidance system.

The description given so far of advantageous configurations of the invention contains numerous features, some of which are combined into several in the individual subclaims. However, these features can expediently also be considered individually and combined to form further meaningful combinations. In particular, these features can each be combined individually and in any suitable combination with the vehicle interior ceiling according to the invention, the lighting system, the vehicle and/or the use according to the invention. Thus, method features are also to be seen formulated as a property of the corresponding device unit and vice versa.

FIG 1 shows schematically a first vehicle interior cover 2 with a multiplicity of webs 4 which are spaced apart from one another. The webs 4 run in the longitudinal direction 6 of the vehicle interior ceiling 2. In the spaces 8 between the webs 4, channel-shaped depressions 10 are formed. The channel-shaped depressions 10 each run in the longitudinal direction 6 of the vehicle interior ceiling 2.

FIG 2 shows the first vehicle interior ceiling 2 FIG 1 in cross section.

The vehicle ceiling 2 in FIG 1 and FIG 2 comprises a plurality of light strips 12. In this exemplary embodiment, the light strips 12 are arranged in a number of the intermediate spaces 8. In principle, a light strip 12 can also be arranged in each of the intermediate spaces 8 . Additionally or alternatively, light bands 12 could also be arranged on at least several of the webs 4 (cf. 6 ).

The multiple light bands 12 run in the longitudinal direction 6 of the vehicle interior ceiling 2.

Each of the light strips 12 comprises a plurality of luminous bodies 14 (cf. FIG 2 ). In FIG 2 some lamps 14 are switched on, for example, so that these lamps 14 generate a light cone 15 .

Each of the channel-shaped indentations 10 in a respective intermediate space 8 is laterally delimited by respective adjacent webs 4 . In addition, each of the depressions 10 is limited in depth by a respective connecting element 16 which connects the adjacent webs 4 to one another. In addition, each of the depressions 10 is limited in height by a respective opening 18 of the respective intermediate space 8 .

In this exemplary embodiment, the vehicle interior ceiling 2 includes a profile plate 20. The profile plate 20 is designed in particular as a profile sheet. The profile plate 20 has the webs 4 mentioned above and the intermediate spaces 8 mentioned above. For example, the profile plate 20 is designed as a trapezoidal plate, in particular as a trapezoidal sheet.

Each of the webs 4 comprises two web sides 22 and a web front 24 connecting the web sides. In this exemplary embodiment, the web sides 22 are at an obtuse angle 26 to the web front 24. However, a different angle could also be chosen.

Each of the luminous bodies 14 has a light exit direction 28 . In this example, the light exit direction 28 is a central light exit direction 28. The light exit directions 28 of the luminous bodies 14 point at least essentially to the opening 18 of that intermediate space 8 in which the respective light band 12 is arranged. To this way, direct lighting can be provided.

The light bands 12 of the vehicle interior ceiling 2 can be controlled individually and/or in groups. This means that each of the light strips 12 can be switched on and/or off individually.

For the sake of clarity, elements that occur several times are not always provided with reference symbols. Identical elements can be mentally supplemented with identical reference symbols.

3 shows a light band 12 of the vehicle interior ceiling 2 FIG 1 and FIG 2 . The light band 12 comprises a plurality of luminous bodies 14. The luminous bodies of the light bands can be controlled individually and/or in groups. In this exemplary embodiment, the luminous bodies are in the form of LEDs.

The light band 12 can be divided into several segments 30, for example. The luminous body 14 of a respective segment 30 can form a common group 32 . In addition, the luminous bodies of several segments 30 of several light bands 12 can also form a common group 32 (not shown).

In principle, the groups 32 do not have to be formed in segments. For example, every second luminous body 14 of a respective light band 12 could also form a common group 32 . Other design options are conceivable.

FIG 4 shows schematically a second vehicle ceiling 34 in cross section.

The following description is essentially limited to the differences from the exemplary embodiment 1 to 3 , to which reference is made for features and functions that remain the same. Elements that remain essentially the same are always denoted by the same reference numerals and features that are not mentioned are included in the following exemplary embodiment without being described again.

The vehicle interior ceiling 34 comprises a plurality of profile elements 36. Each of the profile elements 36 has at least one part 38 of a web 4 and a connecting element 40 for connecting adjacent webs 4. In this exemplary embodiment, each profile element 36 comprises part 42 of a web front 24, a web side 22 and a connecting element 40. Part 42 of a web front 24 of a profile element 36 forms a common web front 24 with part of a web front 24 of the adjacent profile element 36. In addition, adjacent Webs 4 are each connected by two connecting elements 40 of respectively adjacent profile elements 36 .

In this exemplary embodiment, part 42 of web front 24 runs parallel to connecting element 40 in each profile element 36. In addition, part 42 of web front 24 is at right angles 44 to the respective web side 22.

The profile elements 36 are mutually displaceable in their transverse direction. In FIG 4 the expanded state of the profile elements 36 is shown.

Adjacent connecting elements 40 partially overlap one another in order to ensure that the profile elements 36 can be displaced. Adjacent parts 42 of a respective web front 24 also partially overlap in order to ensure that the profile elements 36 can be displaced.

The light bands 14 are in FIG 4 arranged in the spaces 8 between the webs 4. In this example, the light bands are fastened to one of the connecting elements 40 delimiting the depth of the respective depression 10 . Preferably, the light bands are on those connecting elements 40 fixed, which the adjacent connecting element 40 partially overlaps.

Additionally or alternatively, (the same or additional) light bands 12 could be arranged on the web fronts 24 (cf. 6 and 7 ).

5 12 shows the second vehicle ceiling 34 FIG 4 with the profile elements 36 in the collapsed state. When pushed together, the profile elements 36 overlap each other completely or almost completely. In particular, when the profile elements 36 are pushed together, the connecting elements 40 of adjacent profile elements 36 overlap completely or almost completely. In addition, when the profile elements 36 are pushed together, the parts 42 of the web fronts 24 of adjacent profile elements 36 overlap completely or almost completely.

By pushing the profile elements 36 together, the gaps 8 between the webs 4 are reduced. In addition, by pushing the profile elements 36 together, the distances 46 between the web sides 22 of a respective web 4 are reduced.

Due to the displaceability of the profile elements 36 against each other, the width of the vehicle interior ceiling is variable.

6 shows schematically a third vehicle ceiling 48 in cross section.

The following description is essentially limited to the differences from the exemplary embodiment 4 and 5 , to which reference is made for consistent features and functions. Elements that remain essentially the same are generally denoted by the same reference symbols, and features that are not mentioned are included in the following exemplary embodiment without being described again.

The third vehicle interior cover 48 comprises a plurality of profile elements 50.

Each of the profile elements 50 comprises one of the webs 4 and a connecting element 52 for connecting adjacent webs 4. The profile elements 50 can be displaced relative to one another in their transverse direction. In addition, the profile elements 50 can be at least partially overlapped in the transverse direction. This ensures that the profile elements 50 can be displaced relative to one another.

In 6 the profile elements 50 of the third vehicle inner cover 48 are shown in their extended state.

In this exemplary embodiment, the light bands 12 of the vehicle interior ceiling 48 are arranged on the webs 4 . In particular, the light bands 12 are arranged on the web fronts 24 .

In this embodiment, the web sides 22 are at an obtuse angle 26 to the web front 24.

FIG 7 12 shows the third vehicle ceiling 48 6 , wherein the profile elements 50 are in their collapsed state.

When pushed together, the adjacent profile elements 50 overlap one another. In particular, a connecting element 52 is covered by the web 4 of the adjacent profile element 50 . In this way, the depressions 10 are at least partially covered. In particular, the gaps 8 between the webs 4 are reduced by pushing the profile elements 50 together. The distances 46 between the web sides 22 of a respective web 4 remain constant when the profile elements 50 are pushed together.

8 shows a fourth vehicle ceiling 54 in cross section.

The following description is essentially limited to the differences from the exemplary embodiment 4 and 5 , to which reference is made for consistent features and functions. Elements that remain essentially the same are generally denoted by the same reference symbols, and features that are not mentioned are included in the following exemplary embodiment without being described again.

The fourth vehicle interior cover 54 comprises profile elements 56, each of the profile elements 56 having at least one part 58 of a web 4 and a connecting element 60 for connecting adjacent webs 4.

In 8 the profile elements 56 are shown in their extended state. All wells 10 are released.

In this exemplary embodiment, each of the profile elements 56 comprises a web front 24 and a connecting element 60 , the web front 24 being connected to the connecting element 60 via a web side 22 of the same web 4 . In addition, each profile element 56 comprises a further web side 22 which is connected to the first-mentioned web side 22 via the connecting element 60 .

In this exemplary embodiment, each of the profile elements 56 has a U-profile 62 and a tab 64 . The U-profile 62 includes two flanges 66. Each of the flanges 66 has a lower end 68 and an upper end 70, respectively. Channel 62 also includes a base 72 that connects flanges 66 together at lower ends 68 thereof. The tab 64 is arranged at the upper end 70 of one of the flanges 66 of the U-profile 62 . In this case, the tab 64 is aligned parallel to the base 72 of the U-profile 62 .

The tab 64 forms the web front 24 mentioned above. In addition, the flanges 66 of the U-profile 62 each form web sides 22 of adjacent webs 4 . Furthermore, the base 72 of the U-profile 62 forms the aforementioned connecting element 60 .

The light bands 12 are arranged in the intermediate spaces 8 of the vehicle interior ceiling 54 . In this example, the light bands 12 are attached to the respective base 72 of the U-profile 62.

9 12 shows the fourth vehicle ceiling 54 8 , wherein the profile elements 56 are in their collapsed state. The distances 46 between the web sides 22 of a respective web 4 are reduced when pushed together.

When the profile elements 56 are pushed together, the web fronts 24 of the profile elements 56 each cover the depression 10 of the adjacent profile element 56. When the profile elements 56 are pushed together, the web fronts 24 of the profile elements 56 close in particular the openings 18 of the intermediate spaces 8.

In this way, the skylights are protected when the profile elements are pushed together.

10 shows a fifth vehicle ceiling 74 in cross section.

The following description is essentially limited to the differences from the exemplary embodiment 8 and 9 , to which reference is made for consistent features and functions.

14 shows schematically a rail vehicle 80 with at least one carriage 82 in cross section. The rail vehicle 80 includes a lighting system 84. The lighting system 84 has one of the vehicle interior ceilings 2, 34, 48, 54, 74, 78 mentioned above. The vehicle interior ceiling 54 is shown here as an example 8 shown.

In principle, the rail vehicle 80 could also have a different vehicle interior cover with the features of claim 1 .

In addition, the lighting system 84 has a control unit 86 which is set up to control the lighting elements 14 of the light strips 12 of the vehicle interior ceiling 54 individually and/or in groups. The vehicle ceiling 54 is connected to the control unit 86 via a data connection 88 .

The vehicle interior ceiling 54 delimits an interior space 90 of the rail vehicle 80 at the top. Uniform illumination of the interior 90 of the rail vehicle 80 can be ensured with the vehicle interior ceiling 54 .

The luminous bodies 14 can be switched on and/or off individually and/or in groups by means of the control unit 86 (not shown).

For example, only some of the luminous bodies 14 of the multiple light strips 12 can be switched on at a given point in time. In this way, the service life of the light bands 12 can be increased. For example, at one point in time, every second lamp 14 can be switched on and the other lamps 14 are switched off. You can switch after a certain amount of time. For example, the luminous element 14 can be changed after the average service life.

Furthermore, the light intensity of the luminous bodies 14 can be controlled individually and/or in groups by means of the control unit 86 . In this way, the light intensity of the luminous element 14 can be adjusted to a time of day. In addition, different areas of the interior 90 can be illuminated with different brightness.

The light color of the luminous bodies 14 can also be controlled individually and/or in groups by means of the control unit 86 . For example, the color temperature of the luminous elements 14 can be adapted to a time of day.

In addition, the vehicle interior ceiling 54 can be used to display information for a passenger inside the rail vehicle 80 (cf. 15 and 16 ).

15 FIG. 12 shows the use of the vehicle ceiling 54. FIG 14 to display a passenger seat occupancy.

In this example, the lighting elements 14 form those light bands 12 which are above a central aisle of the rail vehicle 80 14 are arranged, a first group 92. The filaments 14 of the first group 92 glow white. In this way, the center aisle of the rail vehicle 80 is well illuminated.

The light bands, which are located above the passenger seats of the rail vehicle 80, indicate passenger seat occupancy in terms of color.

In this example, those lighting elements 14 which are above a respective passenger seat of the rail vehicle 80 form 14 are arranged, a respective second group 94. In this way, it can be displayed above each passenger seat whether the respective passenger seat is occupied or not.

For example, an occupied passenger space can be symbolized by a red light, whereas a free space can be indicated by a green light.

The luminous body 14 of that group 94 which is located above an occupied passenger seat glows red (not shown). The lighting elements 14 of that group 94 which is located above a free passenger space light up green (not shown).

The rail vehicle can have various sensors in order to determine the occupancy of passenger seats.

In addition, the passenger seat occupancy for several seat groups could also be displayed. For example, a seat group that is completely free could be indicated by a green light over this seat group. A partially occupied group of seats, on the other hand, could be symbolized by a yellow light. A fully occupied group of seats, on the other hand, could be symbolized by a red light.

In principle, it would also be possible to display the passenger seat occupancy by car.

The passenger flow within the rail vehicle 80 can be influenced by using the vehicle interior ceiling 54 to display a passenger space occupancy. In particular, passengers can be directed to free seats. In this way, passengers can be guided more quickly to free seats. In particular, passenger changeover times can be reduced in this way.

16 shows a use of the vehicle ceiling 54 from 14 for direction indication.

For example, the lighting elements 14 of the light bands 12 can produce an arrow-shaped light image 96 as a direction indicator for guiding a passenger. The light image 96 can be a still light image or a running light image.

For example, shortly before the rail vehicle 80 stops 14 or in an emergency situation, the arrow-shaped light image 96 can show the shortest route to the next exit of the rail vehicle 80 . The light image 96 is visible at all times, regardless of how many passengers are in the aisle.

In this example, those filaments 14 that are intended to display the arrow-shaped light image 96 form a first group 98. The filaments of the first group 98 light up in color, for example green (not shown).

Other luminous bodies 14 which are in the immediate vicinity of the arrow-shaped light image 96 can form a second group 100 . The luminous bodies 14 can glow white (not shown).

Further light bodies 14, which are arranged, for example, on the sides of the rail vehicle 80, can form a third group 102. The light bodies 14 of the third groups 102 may be turned off (not shown).

Although the invention has been illustrated and described in detail by the preferred embodiments, the invention is not limited by the disclosed examples and other variations can be derived therefrom by a person skilled in the art without departing from the protective scope of the claims.
