Description

The invention relates to a device and a method for positioning an auxiliary device in the door region of a rail vehicle and a rail vehicle.

Rail vehicles may have auxiliary equipment, e.g. Lighting devices, which are e.g. assist or facilitate the entry and exit of passengers. Rail vehicles often have so-called sliding doors, in particular sliding sliding doors. When opening such a vehicle door, at least one of the door wings may impair a function of the auxiliary device, for example by the door panel covering a lighting area of a lighting device.

The US Pat. No. 7,175,320 B1 discloses an adjustable, raised and externally mounted lighting device for vehicles such as school buses. The lighting device provides a lighting area for an entry and exit area in order to provide better visibility for passengers, drivers and other vehicle operators in the vehicle environment. However, the disclosed lighting device is only once, in particular before operation, positioned and arranged stationary after positioning. In particular, no actuator-supported positioning of the illumination device is taught.

The US 5,669,704 A discloses a security system for a vehicle comprising an external mirror assembly and a light module removably disposed within a housing.

The GB 2488862 A discloses an illumination assembly for a vehicle or trailer, wherein an adjustable illumination support means is fitted into an outer housing. The assembly adjusts various vertical angles for an outward light projection covering a surface in the surrounding area below and adjacent to the vehicle.

The US 5,209,559 A discloses a vehicle lighting system for use with trucks or trailers which assists a vehicle operator in observing a vehicle environment in the rear area. The lighting system comprises a lighting unit that is mounted below a vehicle body but above and in front of and / or behind rear wheels.

The technical problem arises of providing a device and a method for positioning an auxiliary device in the door region of a rail vehicle and a rail vehicle, which enable increased reliability of the rail vehicle.

The solution of the technical problem results from the objects with the features of claims 1, 8 and 10. Further advantageous embodiments of the invention will become apparent from the dependent claims.

It is a basic idea of the invention that an auxiliary device, e.g. a lighting device, by a positioning relative to the rail vehicle and can be extended.

A device for positioning an auxiliary device in the door region of a rail vehicle is proposed. A positioning here refers to a change of position. However, as will be explained in more detail below, positioning may also denote or include a change in an orientation of the auxiliary device.

An auxiliary device can in particular be a lighting device, an image capture device or an information device, for example a vehicle information device. Also, the auxiliary device may comprise several of the aforementioned devices.

A door region of the rail vehicle here refers to a region of an outer wall of the rail vehicle, which comprises at least one door opening, wherein the door opening denotes an opening in the outer wall, in which a door is arranged in the closed state. Preferably, the door region also comprises subregions of the outer wall, which are arranged adjacent to the door opening, in particular areas the outer wall extending along a vertical axis of the rail vehicle above and / or below the door opening and / or along a longitudinal axis of the rail vehicle in front of and / or behind the door opening and / or along a lateral axis of the rail vehicle to the right of and / or to the left of the door opening Door opening are arranged. The door area and / or a partial area may in this case have predetermined dimensions.

Furthermore, the device comprises at least one stationary relative to the rail vehicle can be arranged part. This part can also be called a stationary part. The stationary part has at least one fastening means for fastening the stationary part to the rail vehicle, in particular in the door region of the rail vehicle, or comprises or forms such a fastening means. Here, the rail vehicle may have at least one corresponding fastening means, wherein the fastening means of the fixed part and the rail vehicle can interact with each other to produce a solid, in particular rigid, mechanical connection between the stationary part and the rail vehicle. Thus, the stationary part can be arranged relative to the rail vehicle, in particular relative to a coordinate system of the rail vehicle, stationary on the rail vehicle. A coordinate system of the rail vehicle may hereby be formed by a vehicle longitudinal axis, which may be referred to as a longitudinal axis, a vehicle transverse axis, which may be referred to as a lateral axis, and a vehicle vertical axis, which may also be referred to as a vertical axis. The vertical axis may be oriented from bottom to top when oriented from a vehicle floor toward a vehicle roof. The longitudinal axis may be oriented from back to front when oriented from a rear area to a front area. The lateral axis may be oriented from right to left when oriented from a right side wall of the vehicle to a left side wall of the vehicle with a viewer looking forward in the direction of the longitudinal axis.

Furthermore, the auxiliary device is a lighting device. The illumination device may in this case comprise at least one illumination source, for example an LED. In this case, the illumination device can be fastened or arranged on the movable part in such a way that a lighting area comprises at least partially, preferably completely, an entry and exit area assigned to the vehicle door. The one and exit area may in this case be arranged along the vehicle transverse axis next to the vehicle, so include areas of a platform, a sidewalk or a road, but also areas in the passenger compartment. An illumination of the entry and exit area can be done during a stay of the vehicle at a stop, but also in the evacuation case. The illumination device can generate light with a predetermined light intensity.

The rail vehicle may further include an extendable and extendable or retractable entry and exit ramp, for example for wheelchairs. In this case, this entry and exit ramp can be illuminated even in an extended or unfolded state in a desired manner, in particular completely, with a predetermined light intensity. Furthermore, the device and / or the illumination device can be arranged in such a way that, when the entry and exit ramps are extended or unfolded, an area lying along the vehicle longitudinal axis in front of the entry and exit ramps is illuminated by the illumination device. This advantageously illuminates reflective elements of the entry and exit ramps, which makes them e.g. For subsequent road users improved becomes visible.

Alternatively, the auxiliary device may be an image capture device. As previously explained, a detection area of the image capture device may comprise at least one part, but preferably the complete entry and exit area associated with the door. Thereby, e.g. for a driver to provide improved visual coverage of people getting in and out. For this purpose, the image data generated by the image capture device can e.g. be transmitted to a display device in the cab of the rail vehicle. Of course, the image data can also be transmitted to other receiving devices, for example vehicle-external receiving devices.

Alternatively, the auxiliary device is an information device. This can, for example, generate information for passengers entering and exiting visually, acoustically or in another way. For example, the auxiliary device may be a projection device. This can, for example, project information for passengers boarding and / or exiting to a floor area in front of the vehicle door. Of course, the auxiliary device may also comprise several of the previously explained devices.

The proposed device, in particular the auxiliary device, may also comprise a communication device, in particular a transmitting and / or receiving device, which permits signal and / or data transmission between the device and further in-vehicle and / or vehicle-external devices. The transmission can be done wirelessly or by wire. Thus, for example, control signals for the operation of the device, in particular for the control of the positioning and the operation of the auxiliary device, can be transmitted to the device. Also, signals generated by the auxiliary device can be transmitted to further devices.

According to the invention, the device comprises at least one part movable relative to the stationary part, the auxiliary device being arranged on the movable part, in particular on a free end or in the region of the free end of the movable part. The movable part is actuator-supported between a retracted and extended state movable.

Thus, by a movement of the movable part at least one position of the auxiliary device relative to the stationary part can be changed. In a fixed state of the stationary part is thus a position of the auxiliary device relative to the rail vehicle changeable. The attached state here describes a state in which the stationary part is attached to the rail vehicle.

The retracted and extended states may here designate two end states of the movement of the movable part. Thus, in the retracted state, a distance between a reference point of the auxiliary device, for example, an attachment point of the auxiliary device to the movable part, and a reference point of the stationary part, for example, an attachment point of the stationary part on the rail vehicle, be smaller than the distance between the reference point of the auxiliary device and the reference point of the stationary part in the extended state.

Actuator-assisted may mean that the device comprises at least one device for generating drive energy, wherein the drive energy is generated and / or used to move the movable part. This device may be formed, for example, as an electrical machine. Of course, however, other means for generating drive energy, e.g. Pressure generating devices for a hydraulic or pneumatic drive or internal combustion engine devices, can be used. Furthermore, the device may comprise means for transmitting the drive energy to the moving part. These agents may e.g. allow a mechanical and / or pneumatic and / or hydraulic and / or electrical and / or magnetic transmission of drive energy.

Furthermore, the device may comprise at least one guide means for guiding the movement of the movable part. The guide means may be formed in particular as a bearing device. The at least one guide means may in particular allow a linear guide of the movable part.

Furthermore, in the extended state of the movable part and in the fixed state of the stationary part, the auxiliary device can project from the outer wall over the door of the rail vehicle in the opened state.

Further, the auxiliary device is in the extended state of the movable member spaced or disposable at a distance from the outer wall of the rail vehicle, which is larger, in particular by more than a predetermined amount is greater than a maximum distance of the open (vehicle) door of the exterior wall. In particular, the device may be designed such that in the mounted state, the auxiliary device is arranged in the extended state of the movable part at a distance from the outer wall of the rail vehicle spaced greater than a maximum distance of the open (vehicle) door from the outer wall ,

The outer wall of the rail vehicle here refers to a wall through which an inner region of the rail vehicle, which e.g. a passenger compartment, is separated from an outdoor area.

In particular, the auxiliary device in the extended state of the movable part along the above-described vehicle transverse axis, ie the lateral axis, be arranged further away from the outer wall than the door in the open state, for example as a wing of the sliding door in the open state.

In particular, an adjustment path between the retracted and extended states can be greater than a maximum adjustment path of the vehicle door along the vehicle transverse axis. The maximum displacement of the movable part may be, for example, 0.3 m or 0.5 m. This results in an advantageous manner that the auxiliary device is not impaired in functionality by the open door.

The adjustment can be an adjustment of the proposed device.

Thus, the feature that the auxiliary device in the extended state of the movable member is spaced apart from the outer wall of the rail vehicle, which is greater than a maximum distance of the open door from the outer wall, mean that a displacement of the device between the one - and extended state is greater than a maximum displacement of the vehicle door along the vehicle transverse axis.

It is conceivable that an adjustment path between the retracted state and the extended state is position-dependent (vehicle position-dependent) is set. For this purpose, the device can determine a position of the rail vehicle and an adjustment path associated with the position. The position can be a position in a global reference coordinate system. For example, the device may comprise at least one device for position determination, in particular a GNSS device, or be connected to such a device, for example a device of the rail vehicle, in terms of data and / or signaling.

For example, each position or predetermined position ranges can each be associated with travel ranges. In particular, positions or position areas that are assigned to a stop or station of the rail vehicle may be assigned stop or station-specific travel paths. In this way, the movable part can be positioned in the extended state stop or station specific. Thus, the movement can be adapted advantageously to the nature of a stop or station, for example, to different distances between platform and rail vehicle.

Also, a stop or station side arranged communication device can transmit position information to the device. For this purpose, the device may have a corresponding communication device. Of course, a stop or station side arranged communication device can also transmit a stop or station-specific adjustment to the device.

This results in an advantageous manner, a device that allows an actuator-based positioning of the auxiliary device relative to the rail vehicle.

In particular, by means of the device, the position of the auxiliary device relative to the rail vehicle can be changed quickly in time and without manual operation. As will be explained in more detail below, for example, the device allows the auxiliary device to be moved away from a side wall of the vehicle so that the auxiliary device in the extended state can be moved e.g. protrudes beyond an entry and exit area of the door. As a result, a restriction of the functionality of the auxiliary device by further vehicle parts, such as an open door of the vehicle can be avoided in an advantageous manner. In addition, the movable part can also be moved manually. For example, it is possible that the device comprises a Notentriegelungsmechanismus, wherein the movable part can be set by operation or activation of the emergency release mechanism in a powerless state, wherein the movable part can be moved in the powerless state by manual operation. For example, the movable part may be disconnected from the means for generating drive energy by actuation or activation of the emergency release mechanism. In this way, the movable part can be moved in case of damage in the retracted state in an advantageous manner, whereby a further travel of the rail vehicle is enabled without Envelope.

In a further embodiment, in a fixed state of the stationary part, the movable part is movable away from the outer wall, in particular from a side wall, of the rail vehicle during a movement from the retracted to the extended state.

This may mean that a distance, in particular a minimum distance, between the auxiliary device and the outer wall of the rail vehicle during the movement the retracted in the extended state increases at least in sections. Accordingly, the distance can decrease at least in sections during a movement from the extended to the retracted state.

During the movement from the retracted to the extended state, a movement direction along the entire trajectory or at least along a part of this trajectory can comprise at least one component which is oriented parallel to the vehicle transverse axis explained above. It is also conceivable that the direction of movement along the entire trajectory or at least along part of this trajectory is oriented completely parallel to the vehicle transverse axis. However, the direction of movement along the entire trajectory or at least along part of this trajectory may also include portions which are oriented parallel to the vehicle vertical axis and / or parallel to the vehicle longitudinal axis. The previously explained distance can also be detected, for example, along the direction of movement.

In a preferred embodiment, the auxiliary device is arranged in the retracted state completely behind the outer wall of the rail vehicle in a fixed state of the stationary part.

In particular, but not necessarily exclusively, in this embodiment, the outer wall can have a recess or opening into which the movable part can move from the extended to the retracted state upon movement. The fact that the auxiliary device is arranged completely behind the outer wall may mean that the auxiliary device is completely arranged in an inner volume enclosed by an envelope or envelope surface of the rail vehicle.

Furthermore, the device or the rail vehicle may comprise at least one cover element, which, in particular in the retracted state, covers the recess or opening explained above. The cover element, for example a cover plate, can also be arranged at the free end or in the region of a free end of the movable part. In particular, the cover in the retracted state can cover the recess or opening and be arranged flush with adjacent areas of the outer wall.

Also, the cover, in particular a cover element arranged on the rail vehicle, release the recess or opening during the movement from the retracted to the extended state. In this case, the cover can be suitably mechanically coupled to the movable part, for example.

In a further embodiment, the movement between the retracted state and the extended state is a linear movement or a pivoting movement.

In particular, but not necessarily exclusively, in this embodiment the device may comprise a linear drive system or a linear drive device. For example, such a linear drive system may comprise a ball screw, a roller screw, a hydraulic cylinder or a pneumatic cylinder or be designed as an electromechanical linear drive. As previously explained, the linear movement can only take place parallel to the vehicle transverse axis. Alternatively, however, the linear movement may include portions that are oriented parallel to the vehicle transverse axis, to the vehicle vertical axis and / or to the vehicle longitudinal axis.

Alternatively, the movement between the retracted state and the extended state may be a linear motion or a pivotal movement. The pivoting movement can be carried out here about a rotation axis whose orientation in the vehicle coordinate system has at least one component which is oriented parallel to the vertical axis. Also, the axis of rotation can be oriented completely parallel to the vertical axis. In this case, a maximum pivoting angle can be predetermined, which lies between the retracted state and the extended state, for example a pivoting angle of 90 °.

This results in an advantageous manner as simple as possible movement away from the outer wall of the rail vehicle.

In a further embodiment, before or during or after opening at least one door of the rail vehicle associated with the door region, a movement into the extended state is carried out.

For example, a control device for controlling the vehicle door, which controls the opening and closing of the door, data and / or signaling technology with a control device that controls the movement of the movable part of the proposed device, be connected.

Furthermore, the control device for controlling the movement of the movable part can detect the opening of the vehicle door. For example, the control device for controlling the vehicle door can transmit an opening signal to the control device for controlling the movement of the movable part.

If the opening of the vehicle door is detected, the control device for controlling the movement of the movable part can control the proposed device such that the movable part is moved from the retracted to the extended state.

Accordingly, before or during or after a closing of the door region of the associated door of the rail vehicle, a movement into the retracted state can be performed.

This results in an advantageous manner that the auxiliary device is automatically, but in particular only in the extended state is moved when the vehicle door is opened or is.

The proposed device may in this case comprise the previously explained control device for controlling the movement of the movable part.

In a further embodiment, a drive energy for moving the movable part, or at least part of it, is generated by a device for generating drive energy for a movement of the door. In particular, the movable part may be mechanically coupled to the means for generating drive energy for the movement of the door. It is conceivable, for example, that the movable part is mechanically coupled to a movable part for actuating the vehicle door.

In particular, the movable part may be mechanically coupled to the device for generating drive energy for the movement of the door such that the moving part is moved in the operation of the means for generating drive energy for opening the door in the extended state and is moved in the operation of the means for generating drive energy for closing the door in the retracted state.

In a further embodiment, an orientation of the auxiliary device relative to the stationary part is additionally variable by the device. In this way, for example, an orientation of the auxiliary device can be changed in the extended state. To change the orientation, the device may comprise a further device for generating drive energy and / or further means for transmitting drive energy and / or further guidance means.

Further proposed is a rail vehicle. The rail vehicle comprises at least one vehicle door. The at least one vehicle door is arranged in a door region of the rail vehicle. As explained above, the door area can comprise, in addition to the door opening, further subregions of an outer wall, in particular a side wall, in particular areas which are arranged adjacent to the door opening.

Furthermore, the rail vehicle comprises at least one device according to one of the previously explained embodiments. The fixed part of the device is attached to the rail vehicle. In particular, the stationary part may be fastened to a wall section of the rail vehicle, in particular a wall section, for example a side wall section, in the door region of the rail vehicle. For example, the fixed part may be attached to a part of the vehicle structure, for example to a side wall frame or a roof frame, or to a vehicle part in the door area, e.g. be attached to a door drive module, a Voutenfixteil, a door protection box or a Außenverblechung.

In particular, the device, more particularly the fixed part of the device, can be fastened to the rail vehicle and arranged such that the moving part can be moved away from an outer wall of the rail vehicle when moving from the retracted to the extended state, in particular with one linear motion. This has been explained previously.

Further, the auxiliary device in the retracted state can be arranged completely behind an outer wall of the rail vehicle.

This results in an advantageous manner a rail vehicle with increased reliability.

In this case, the rail vehicle may in particular also include the previously explained device for generating drive energy for a movement of the door. The door of the rail vehicle may in particular be an actuator-supported movable door, more particularly a pivot sliding door.

In a further embodiment, the device is arranged off-center in the door area with respect to a vehicle longitudinal axis. This advantageously results in that further devices, for example sensors, can be arranged in the region, in particular in a central region of the door region, without being disturbed by the proposed device. However, the device may also be arranged centrally in the door region with respect to the vehicle longitudinal axis.

Further proposed is a method for operating a device according to one of the previously explained embodiments. In this case, the movable part is moved after receiving an exit signal from the retracted state to the extended state. Further, the movable part is moved to the retracted state upon receipt of an entrance signal from the extended state. The extension signal and the entry signal can in this case be transmitted, for example, to the previously explained control device for controlling the movement of the movable part.

This results in an advantageous manner a simple operation of the proposed device in a rail vehicle.

In a further embodiment, a door opening signal is or generates the exit signal. Further, a door closing signal is or generates the entry signal.

This advantageously results in a preferably simultaneous opening of the door and a movement in the extended state, wherein also preferably a simultaneous closing of the door and a movement takes place in the retracted state.

Hereinafter, like reference numerals designate elements having the same or similar technical features.

In Fig. 1 is a schematic cross section through a rail vehicle 1 shown with a device 2 according to the invention in the retracted state. Shown is a roof area 3 of the rail vehicle, which comprises a roof 4 of the rail vehicle and a ceiling 5 of a passenger compartment 6 of the rail vehicle 1. Also shown is a bottom 7 of the passenger compartment 6. Further shown is a side wall 8 in a door region of the rail vehicle 1 and a door 9, which may be formed in particular as a sliding sliding door. Here, the door 9 is shown in a closed state. The side wall 8 has a door opening 18 (see Fig. 2 ), in which the door 9 is arranged in the closed state. When closed, an outer surface of the door 9 is flush with the outer surface of the side wall 8.

Also shown is a vehicle coordinate system having a vertical axis z which is oriented parallel to a vehicle vertical axis and points from the floor 7 to the roof 4. Also shown is a lateral axis y, which is oriented parallel to a vehicle transverse axis and points in the illustrated embodiment from right to left. Not shown is a longitudinal axis, which is oriented parallel to a vehicle longitudinal axis and in Fig. 1 pointing into the drawing plane.

In the vertical direction, which is represented by an arrow of the vertical axis z, above the door opening 18, the device 2 is arranged. Here, the device 2 is arranged in a space between the ceiling 5 of the passenger compartment 6 and the roof 4. However, it is also conceivable that the device 2 is arranged in the region of the side wall 8 above the door opening 18 of the rail vehicle 1.

The device 2 comprises a stationary part 10, which is fastened to the rail vehicle 1. The stationary part 10 is thus fixed in position relative to the vehicle coordinate system on the rail vehicle 1. Furthermore, the device 2 comprises a movable part. The movable part comprises a carriage 11, or is designed as such, which is movable by an actuator 12. The carriage 11 can in this case be moved in or against a direction which is oriented parallel to the lateral axis y. At a free end of the carriage 11, a lighting device 13 is arranged, with respect to Fig. 2 will be explained in more detail. At the illumination device 13, a cover 14 is arranged.

The side wall 8 has an opening 15 (see Fig. 2 ), by which the carriage 11, the illumination device 13 and the cover 14 can be moved. When retracted, an outer surface of the cover member 14 is flush with an outer surface of the side wall 8. The lighting device 13 is in the retracted state completely behind the side wall 8, that is arranged in an inner volume of the rail vehicle 1.

By operation of the actuator 12, the carriage 11 and thus also the illumination device 13 can be moved to an extended state, which in Fig. 2 is shown.

In Fig. 2 is a schematic cross section through the in Fig. 1 illustrated rail vehicle 1 shown. Here, the device 2, in particular the carriage 11, shown in an extended state. Also, the door 9 is shown in an open state. Also shown is a distance D9 between the position of the outer surface of the door 9 in the open state and in the closed state. Also shown is a distance D11 of the illumination device 13 between a position in the extended state and in the retracted state, this distance D11 being equal to the distance between the position of the outer surface of the cover 14 in the open state and in the closed state.

The distance D11 may correspond to a travel of the device 2 or of the movable part. Thus, the travel of the device 2 is greater than a travel of the door movement parallel to the lateral axis y.

Next is out Fig. 2 It can be seen that the illumination device 13 is arranged along the lateral axis y behind the door 9 in the opened state. Schematically illustrated is an illumination area 16 of the illumination device 13, wherein this illumination area 16 is only minimally restricted by the opened door 9. In particular, the illumination area 16 comprises at least part of an entry and exit area, which is associated with the door 9.

In Fig. 3 a side view of a door area in a side wall 8 of a rail vehicle 1 is shown. Also shown is a longitudinal axis x which is in the in Fig. 3 illustrated embodiment is oriented from a vehicle rear to a vehicle front.

Also shown is a door 9 formed by two door leaves, which is designed as a sliding sliding door. The door 9 is shown in an open state. Also shown is a cover member 14 and a lighting device 13, which at a free end of an example in Fig. 5 are shown movable part 11 are arranged. Here it is shown that the illumination device 13 is arranged both in the retracted and in the extended state along the vehicle longitudinal direction, which is symbolized by an arrow of the longitudinal axis x, in front of a central region of a door opening 18 and thus with respect to the vehicle longitudinal direction off-center in the door area , The central region can in this case in particular an area with a predetermined Width in the longitudinal direction, the contact surfaces of the door in the closed state of the door 9 includes.

Next is in Fig. 3 illustrated that the rail vehicle comprises a further auxiliary device 17, which may be formed, for example, as an image capture device. Persons and / or objects in the previously explained entry and exit area, which is associated with the door 9, can be detected by means of the image capture device 17. In this case, a lighting area 16 (see, for example, FIG. Fig. 4 ) and a detection range of the image capture device 17 overlap. The image capture device 17 is hereby arranged with respect to the vehicle longitudinal axis in the central region, in particular in the center, in the door region.

In Fig. 4 is a perspective view of the in Fig. 3 illustrated door area shown. Here, the device 2 (see, eg Fig. 1 ) in the extended state. In turn, a lighting area 16 of the lighting device 13, which is arranged at the free end of the carriage 11 of the movable part, is shown schematically. Also visible is an opening 15 in the door area of the side wall 8.

Out Fig. 4 and Fig. 5 it can be seen that the lighting device 13 in the extended state of the side wall 8 through the door 9, in particular over a door leaf of the door 9, in the open state protrudes. This results in the smallest possible occlusion of the illumination area 16.

In Fig. 5 is a schematic cross section through the in Fig. 3 and Fig. 4 illustrated door area with the illumination device 13 and the image capture device 17 shown. Here it is shown that along the carriage 11 towards the free end of the carriage 11 first the cover 14 and then the illumination device 13 is arranged. When retracted, the cover 14 conceals the in Fig. 4 illustrated opening 15 in the side wall 8 of the rail vehicle 1. In this retracted state, however, the illumination device 13 is further outside of the rail vehicle 1, in particular in front of the side wall 8, respectively. However, the illumination device 13 can alternatively be arranged completely in or behind the side wall 8.

Fig. 6 shows a schematic side view of a rail vehicle 1 with a pivotable movable part 19 of a device 2 according to the invention in the retracted state. Here, the pivotable movable member 19 is disposed in the vertical direction above the vehicle door 9, wherein a rotation axis RA (see Fig. 7 ) of the pivoting movement is oriented parallel to the vertical axis z. At the free end of the pivotable movable part 19, a lighting device 13 is arranged. Not shown is a stationary part of the device 2, which may be mounted in a roof area 3 of the rail vehicle 1.

In Fig. 7 is a schematic plan view of the in Fig. 6 shown rail vehicle 1 shown with the pivotable movable part 19 in the extended state. The door 9 is shown in the open state. In particular, the axis of rotation RA of the pivoting movement and a maximum pivot angle SW, which is 90 ° in the exemplary embodiment shown, are shown. The swivel angle SW is measured here about the rotation axis RA. In the retracted state, a central longitudinal axis of the pivotable movable part 19 is arranged parallel to the longitudinal axis x. In this case, the axis of rotation RA can be arranged such that in the retracted state, an outer surface of the pivotable movable part 19 is arranged flush with the outer wall 8 of the rail vehicle 1.
