Description

The present invention relates to an arrangement for fastening and making accessible technical components in the roof area of a rail vehicle, a rail vehicle with the arrangement according to the invention and a method for equipping a rail vehicle or a car body with an arrangement according to the invention.

In today's rail vehicles, in particular high-speed trains, for example, technical components, in particular electrical components for example, are positioned at various points within the car body. For example, it is known to use cabinets that house various components, such as relays and contactors. Such cabinets are often located in the longitudinal direction in the outer areas of the rail vehicles. Arrangements of the technical components in the roof area of rail vehicles are also known.

Accommodating the technical components in the roof area makes it possible, in particular, to gain more space in the passenger compartment compared to using cabinets or other devices in the passenger compartment.

It is necessary to service the technical components and replace them if necessary. In particular, such technical components, in particular electrical components, which are connected by plugging them into a fastening means that carries them and enables electrical contact, must be accessible from several sides if possible. Both maintenance, which requires access from one side, for example, and replacement, which requires access in the opposite direction to the insertion direction, are possible.

In particular, since access from two different sides is required, installation space remains unused in known solutions, which is disadvantageous in particular. For example, rows of technical components can be arranged in the roof area of a rail vehicle, but space must remain free in the opposite direction to a possible insertion direction if the technical components have to be replaced.

WO 2005/068256 A1 discloses a device for storage and maintenance of electrical equipment on board a vehicle, comprising a volume and at least one carrier, wherein the carrier includes terminals for providing an electrical connection for the electrical equipment and the carrier allows the electrical equipment between a stowed position and an unstowed position. The volume may include a space between the interior ceiling of the vehicle, the roof of the vehicle, and an upper portion of the walls of the vehicle.

It is an object of the present invention to improve the use of space and the accessibility of the technical components in the roof area of a rail vehicle. A further aim of the present invention is to simplify the assembly of technical components in the roof area of a rail vehicle.

According to a basic idea of the present invention, a space is used between technical components arranged on two sides, in particular electrical components, which are arranged in the roof area of a rail vehicle. This can in particular be a space between two stationary fastening devices in the roof area, to which technical components can be fastened.

The stationary fastening devices can be stationary, that is to say immobile, in particular relative to the roof area of the rail vehicle. The roof area can characterize the area between ceiling elements, in particular interior linings, and the roof of the car body. The concept of the roof area can generally be understood in such a way that transition areas between a ceiling and a side wall of the rail vehicle are also included. Such transition areas can also be referred to as haunch areas. The roof area can be understood as an area that is delimited on the one hand by the car body (in particular a roof of the car body) and on the other hand—in the case of a rail vehicle for passenger transport—by the interior paneling of a passenger compartment.

In terms of their design, the stationary fastening devices do not necessarily have to be specifically and explicitly provided for fastening technical components. In particular, they do not have to have any explicit fastening means. A basic suitability for attaching technical components to the stationary Fastening devices is sufficient. For example, it cannot be ruled out that a printed circuit board with plug-in attachments can also serve as a stationary fastening device.

An additional movable mounting device is provided in the space. This moveable mounting device may be in a first position in which other engineering components attached to it are located between engineering components attached to the stationary mounting devices. The moveable mounting device may be in the first position within the space. The movable fastening device can in particular be movable relative to the roof area.

The moveable attachment device may be in a second position in which it is pivoted away, for example folded away, relative to the first position. Pivoting or folding away can be realized, for example, by a joint. It can be a joint that allows pivoting movement about one or more axes of rotation. Alternatively or additionally, it can be, for example, a slotted guide or a linkage that enables a pivoting movement.

When the moveable mounting device is in the second position, the space between the stationary mounting devices is accessible, for example, to a fitter or service technician. In this way, the technical components attached to the stationary attachment devices can be serviced and/or replaced. The other technical components that are attached to the movable attachment device can also be serviced and/or replaced.

In terms of its configuration, the movable fastening device does not necessarily have to be specifically and explicitly provided for fastening the further technical components. In particular, it does not have to have any explicit fastening means. A basic suitability for fastening the other technical components is sufficient. For example, it cannot be ruled out that a printed circuit board with plug-in attachments can also serve as a movable fastening device.

The technical and other technical components can be the same or similar and/or can be electrical and/or electronic components. Alternatively or additionally, it can be hydraulic and/or pneumatic components. The stationary fasteners
and the movable fastening device can be designed in such a way that they can accommodate the technical components in the same way. For example, the stationary fastening device and the movable fastening device can enable similar mechanical fastenings, for example using similar fastening means and/or have similar mechanical, electrical, hydraulic or pneumatic connections for the technical components or the further technical components.

In particular, an arrangement is proposed for fastening and making accessible technical components in the roof area of a rail vehicle,
having

• two fastening devices that are stationary relative to the roof area for fastening technical components,
• a moveable attachment device for attaching further technical components,

wherein the movable fastening device is mounted pivotably about at least one axis of rotation relative to the stationary fastening devices in such a way that a pivoting movement of the movable fastening device from a first position into a second position is possible,

• there being a space between the stationary fixtures,
• wherein in the first position the moveable mounting device is within the space,
• wherein in the second position the moveable mounting device is at least partially outside the space.

The rail vehicle can in particular be a railcar or a non-powered car of a high-speed train. However, it can also be any other variant or type of rail vehicle, for example a railcar or a non-powered car of a long-distance train and/or a regional train and/or a local public transport train (e.g. subway, suburban railway, tram ). In particular, the rail vehicle can have a passenger compartment.

The roof area can in particular be the area from the roof of a car body to the upper ceiling of a passenger compartment of the rail vehicle or can include this area.

The space may be limited by a cover. In particular, the space can be limited at the top by the roof of the car body and/or at the bottom by the cover. The cover can be a ceiling element. The space may be above the passenger compartment.

The cover can be designed to be movable, detachable, removable and/or pivotable. Pivoting movement of the movable mounting device may be enabled by the cover being in a moved away, detached, removed and/or pivoted away condition such that the cover does not interfere with the pivoting movement of the movable mounting device.

The cover can be arranged in particular between the space and the passenger compartment of the rail vehicle. The cover can therefore be located in a field of vision for the passengers, in particular on its side facing away from the room. The coverage may range from one of the two stationary mounting devices to the other of the two stationary mounting devices. In particular, the cover can extend from an underside of one of the two stationary fastening devices to an underside of the other of the two stationary fastening devices when the arrangement is considered to be integrated in the roof area of the rail vehicle. The cover may be located near the bottom of each of the two stationary mounts.

For example, the cover may particularly delimit the space in a direction orthogonal to an imaginary connection or to an imaginary plane between the stationary fastening devices. If the arrangement is considered to be integrated in the roof area of the rail vehicle, the imaginary connection can extend in particular in a transverse direction or in a longitudinal direction of the rail vehicle between the stationary fastening devices. The imaginary plane can be horizontal between the stationary mounting devices. A direction orthogonal to the imaginary connection or to the imaginary plane, in which the cover can delimit the space, can in particular, for example, be the height direction or vertical with respect to the rail vehicle. In particular, the cover can be arranged below the stationary fastening devices.

The cover may delimit and/or define the space in its closed position. That is, the shape and size of the space can remain the same in definition as the cover is moved from the closed position. In particular, the cover can have a joint. For example, it may be hinged to one of the two stationary attachment devices. The cover can be connectable to another of the two movable fastening devices, for example by a locking mechanism. The cover does not necessarily have to be directly mechanically connected to the stationary fastening devices. It can also be attached, for example, close to the stationary fastening devices, held, for example, by other ceiling elements or other holding devices.

As already mentioned, the stationary attachment devices can be understood as stationary, i.e. immovable, in the roof (or immovable in relation to the roof). It is also possible to understand the stationary fastening devices as stationary, i.e. immobile, in relation to the car body. The stationary fasteners may be located opposite each other or on opposite sides (although the orientation of the two stationary fasteners need not necessarily face each other exactly). There may be more than two stationary fixtures. In particular, one stationary fastening device can be arranged in an area further to the left in the roof area (e.g. viewed in the transverse direction of the rail vehicle) and the other stationary fastening device can be arranged in an area further to the right in the roof area. One stationary fastening device can also be arranged in an area further forward in the roof area (eg viewed in the longitudinal direction of the rail vehicle) and the other stationary fastening device can be arranged in an area further back in the roof area. An arrangement in the cove area is also possible.

The stationary fastening devices can have, for example, walls, webs, scaffolding, beams and/or other suspensions. When installed, the stationary fastening devices can extend horizontally, for example in a longitudinal direction or in a transverse direction of the rail vehicle. The stationary fastening devices can in particular be fastened to the roof of the car body or be connected to it. The stationary fasteners can also extend downwards in the direction of the passenger compartment, in particular in a cross section. Fastening means can be provided on the stationary fastening devices. For example, one or more rows of fasteners can be located on the stationary fasteners, which can be aligned horizontally in the rail vehicle. Several rows of fasteners can also be arranged vertically above/below one another or next to one another. Fastening means can be or have, for example, hooks, screw holes, recesses, projections and/or mounting rails, in particular top-hat rails. The stationary fastening devices can themselves be mounting rails, in particular top-hat rails, or consist of mounting rails to a significant extent.

In a longitudinal direction, the movable fastening device can have a length of, for example, at most 1.5 m, preferably at most 1.2 m or 1.0 m. The length can in particular correspond to a swivel length (which extends radially with respect to the at least one axis of rotation). The movable fastening device can in particular have a web, a framework, a frame, a support or a wall element or the cover or any other part with a covering function. There may be more than one moveable attachment device. The moveable attachment device can be pivotally mounted, for example by means of a joint and/or a hinge. It can be pivoted around an instantaneous center and/or around a virtual (non-material) axis of rotation. It can be pivotable about more than one axis of rotation. This aspect can be implemented structurally, for example, with the help of a linkage and/or a link guide. Independent of this, the movable fastening device can also be mounted with the aid of a linkage and/or a link guide. As a simple embodiment, the movable fastening device can also be foldable.

The cover can be present as a separate part. The cover can also be pivoted about the at least one axis of rotation and/or another axis of rotation. The cover can therefore be pivotable in such a way that it can complete the pivoting movement from the first position to the second position with the movable fastening device. Alternatively, it can be pivoted in such a way that it can perform its own pivoting movement. The pivoting movement of its own may be necessary, for example, when access to the room is required.

Fastening means, which are referred to below as further fastening means, can be provided on the movable fastening device. Further Fastening means can in particular be or have hooks, screw holes, recesses, projections and/or support rails, in particular top-hat rails. The other fastening means can be configured similarly or identically or identically to the fastening means.

The moveable attachment device can be attached to an auxiliary structure. The auxiliary structure can be arranged in the room and/or outside the room. The auxiliary frame can in particular have supports which are arranged, for example, along the direction of the axis of rotation (in the case of one axis of rotation) or one of the plurality of axes of rotation (in the case of several axes of rotation). The auxiliary frame can have a joint or a hinge, with the aid of which the movable fastening device can carry out the pivoting movement. The auxiliary scaffold can also have a locking mechanism, for example designed to lock a part of the movable fastening device which is located radially on the outside during the pivoting movement.

Alternatively or additionally, the movable fastening device can be mounted differently or on other parts, for example on ceiling panels of the passenger compartment and/or on holding elements located thereon or underneath, for example using a joint or hinge to implement the pivoting movement and/or a locking mechanism for locking .

In the first position, the moveable mounting device may be located within the space such that the further engineering components attached to the movable mounting device are located between the stationary mounting devices and/or between engineering components attached to the stationary mounting devices. In the first position, fastening means, which can be provided on the movable fastening device, can also be located partly or entirely within the space.

If the other technical components fixed to the movable fixing device are located between the technical components fixed to the stationary fixing devices, this means that the space between the technical components is used in an advantageous manner.

When the moveable attachment device is in the second position, this means that the space between the technical components is at least partly not more is occupied by the other technical components. The room is therefore accessible for fitters or maintenance technicians, for example, without the other technical components getting in the way. The other technical components are located on the pivoted movable attachment device.

In the second position, the further technical components fastened to the movable fastening device can be located at least partially outside the room. In the second position, further fastening means, which can be provided on the movable fastening device, can also be located at least partially outside the space.

The movable fastening device and a joint or a hinge (or another mechanism such as a slotted guide or a linkage) for realizing the pivoting movement can be designed such that they can be arranged in the rail vehicle in such a way that the second position is an angled or vertical hanging of the movable fastening device, in particular into a passenger compartment of the rail vehicle. The axis of rotation can be arranged, for example, in the transverse direction or in the longitudinal direction in relation to the rail vehicle, for example realized by means of a joint or hinge or another mechanism such as a link guide or a linkage.

The moveable fastening device can have connections, for example mechanical, electrical, pneumatic and/or hydraulic connections, for the further technical components. It can also have a (combining) electrical interface, for example in the form of a plug and/or clamp connection, for connecting the other technical components to the rail vehicle. The moveable fastening device can also have connections for data transmission for the other technical components. It can also have a (combining) connection for data transmission to connect the other technical components to the rail vehicle, for example in the form of a corresponding data technology interface, which can be designed as a plug, for example. The moveable fastening device can also have a (summary) pneumatic and/or hydraulic interface for connecting the other technical components to the rail vehicle.

The interfaces mentioned can be understood in the sense that a summarizing connection of the attached to the movable attachment device further technical components are created with the rail vehicle. This makes it possible to equip the movable fastening device (equipped with appropriate connections) with further technical components before the movable fastening device is installed in a rail vehicle. The connection to the rail vehicle can then take place in a simple manner via a summarizing interface. The equipped movable fastening device is then to be understood as a module that can be prefabricated, for example.

The arrangement according to the invention enables improved utilization of installation space by using the space between the stationary fastening devices and the technical components fastened to them. Nevertheless, both the technical components and the other technical components are easily accessible. In addition, the movable fastening device can already be equipped or equipped with further technical components before it is installed in the rail vehicle or a car body. This results in a ready-to-install module that can be used in a rail vehicle in a simple and time-saving manner, for example either during manufacture or when retrofitting. This also generally simplifies the installation of the other technical components in the roof area, since each additional technical component does not have to be maneuvered individually into the roof area and fastened there.

It is a basic idea of the present invention that the technical components and the further technical components can be of a similar, identical and/or identical nature. It can be the same components. It is therefore fundamentally possible to attach components both to the stationary attachment devices and to the movable attachment device. Any arrangement may be possible. The movable fastening device therefore advantageously provides an additional fastening option in a confined space, which enables a large number of technical components or other technical components to be made accessible at the same time. This facilitates the maintenance and replacement and, if necessary, the adjustment of the technical components or the further technical components.

The arrangement according to the invention is also advantageous because it makes it possible to easily maintain specified distances between the technical components and/or the other technical components, so that, for example, cooling or fire safety of the components is required, for example depending on the climatic conditions or legal regulations in the area of use of the rail vehicle - is made possible. It is possible for a cooling device to be provided inside the rail vehicle, which, for example, conveys a flow of cooling air through the space.

In one embodiment of the arrangement according to the invention, the movable fastening device is designed with a cover as a common part.

In particular, this may mean that the cover is of suitable construction and has a suitable load-bearing capacity, that it can function as a movable attachment device. In particular, it can have a cross section that provides the required load-bearing capacity. Alternatively or additionally, a web and/or a carrier can be mounted on the cover, for example. The web and/or the carrier can/can serve for reinforcement. Alternatively or additionally, the further technical components can be attached to the web and/or the carrier and/or further fastening means. The cover can generally be made of plastic. A web and/or a carrier can in particular be made of a metallic material. The cover can be in the field of vision of the passengers. The cover can in particular be a ceiling element.

This configuration is advantageous because it is particularly easy to carry out the pivoting movement of the movable fastening device from the first position into the second position, since additional removal, detachment and/or pivoting away of the cover is not required in this case.

In general and without being restricted to the configuration presented, the cover can alternatively be configured as a separate part.

In such an embodiment, the cover can be designed to be particularly light, because it hardly has a load-bearing function. It serves in particular to protect against unauthorized access, for example by passengers. Furthermore, it can be integrated optically into the paneling in the ceiling area inside the passenger compartment. In particular, it can be a ceiling element.

In one embodiment of the arrangement according to the invention, the two stationary fastening devices are arranged opposite one another.

"Oppositely arranged" here means that the space is between the stationary fastening devices and that the stationary fastening devices are arranged on opposite sides of the space. Exact juxtaposition, so that, for example, flat areas of the stationary fastening devices have normal directions that lie in a straight line, can but does not have to be the case.

The stationary fastening devices can, for example, be aligned in such a way that fastening means and/or technical components located on them are aligned towards one another or away from one another. Alternatively, the fasteners of one stationary fastener may face the other stationary fastener and the fasteners of the other stationary fastener may face away from the one stationary fastener. Engineering components attached to one stationary attachment device may face the other stationary attachment device and engineering components attached to the other stationary attachment device may face away from the one stationary attachment device.

This configuration is particularly advantageous because it is structurally particularly easy to implement and offers particularly good use of space.

In one embodiment of the arrangement according to the invention, the movable fastening device has a frame, a carrier, a web or a scaffold.

The structural variants mentioned are particularly easy to construct and manufacture. They can be designed with simple means in such a way that they have a high load-bearing capacity, high stability, a low tendency to vibrate and/or low deflection.

For example, the movable fastening device can have a web whose long cross-sectional side is designed orthogonally to the axis of rotation or to at least one of the axes of rotation, resulting in a high area moment of inertia in the direction of movement. A similar procedure can be used with regard to a frame, a beam or a scaffold. For example, the moveable mounting device may comprise an I-beam or U-beam or T-beam or Z-beam.

In one embodiment of the arrangement according to the invention, the movable fastening device and/or the stationary fastening devices each have at least one support rail, in particular a top-hat rail.

A support rail represents a particularly simple and inexpensive means of attachment for attaching technical components or other technical components. In addition, a support rail can increase the load-bearing capacity and/or the stability of the movable attachment device and/or the stationary attachment devices and reduce the deflection and/or the tendency to vibrate.

Attaching and removing technical components or other technical components is also made easier.

In one embodiment of the arrangement according to the invention, the movable fastening device has a locking mechanism for locking in the first position, in particular a locking mechanism (22; 49) comprising a cam.

A locking mechanism prevents unauthorized access. The locking mechanism can in particular be arranged on an edge of the movable fastening device which is remote from the at least one axis of rotation. A cam is a particularly simple, easy-to-use and inexpensive, yet effective and stable component. The locking mechanism may have a mating part for locking to, for example, one of the stationary attachment devices or another part.

In one embodiment of the arrangement according to the invention, the movable fastening device has at least one electrical connection for the electrical connection of the further technical components and/or an interface for data transmission.

In this configuration, the additional technical components can be at least partially electrical or electronic components and/or components that require an energy supply and/or are designed to transmit, send and/or receive data.

The electrical connection can have, for example, an electrical connector, a plug connector, a terminal point and/or pre-wiring. The electric Port can have multiple physical interfaces. The interface for data transmission can in particular have data plugs, for example connections for data cables. It is not excluded that the interface is designed to be wireless.

The configuration presented enables a particularly simple energy supply for the further technical components and/or a particularly simple data exchange with the further technical components. The moveable fastening device can be prefabricated with the other technical components, in particular as a module, and can be connected to the rail vehicle in a simple manner for the purpose of power supply and/or for the purpose of data exchange.

In one embodiment of the arrangement according to the invention, the arrangement is designed such that at least one technical component and/or at least one further technical component is a contactor, a relay, a data memory, a video recorder, a circuit breaker, a motor protection switch, a zero-crossing switch, a zero-voltage switch and/or an electronic component, in particular an integrated circuit. In particular, at least one of the stationary fastening devices and/or the movable fastening device can have a corresponding electrical connection for the respective type of technical component.

The components mentioned are generally used as standard in rail vehicles. They always require maintenance, repairs and, if necessary, replacement in the event of a defect. Such work can be carried out particularly easily when using the arrangement according to the invention due to the advantageous accessibility. Simple, needs-based cooling can also be implemented. The arrangement according to the invention allows in particular an individual adjustment of the distances between the technical components or the further technical components, so that a cooling air flow that meets the requirements can surround them.

In one embodiment of the arrangement according to the invention, the movable fastening device is mounted so that it can be disassembled and reassembled along the axis of rotation or one axis of rotation of the plurality of axes of rotation.

A possibility of assembly or disassembly along the axis of rotation or, in the case of several axes of rotation, one of the axes of rotation can mean in particular that a lateral displacement of the movable fastening device causes a release from a rotary mechanism, which, for example, establishes the axis of rotation or one of the axes of rotation . For example, the rotating mechanism may include a hinge or joint, longitudinal displacement along the axis of rotation results in loosening of the hinge or hinge components - similar to a room door being lifted. In particular, a displacement of the movable fastening device can cause a bearing journal to disengage from a bearing surrounding it, so that the movable fastening device detaches from the hinge.

The configuration described enables a particularly simple disassembly and assembly of the movable fastening device. This is particularly advantageous for maintenance work or work to replace other technical components. This also provides a particularly simple way of installing or removing a movable fastening device equipped with additional technical components in the rail vehicle.

In one configuration of the arrangement according to the invention, the at least one axis of rotation or one axis of rotation of the plurality of axes of rotation runs along a longitudinal direction or along a transverse direction of the rail vehicle when the arrangement is considered to be integrated in the roof area of a rail vehicle.

The axis of rotation or one axis of rotation of the plurality of axes of rotation about which the movable fastening device moves during the pivoting movement can in particular define the manner in which the movable fastening device moves during the pivoting movement, for example in a passenger compartment.

A course of the axis of rotation or one axis of rotation of the plurality of axes of rotation in the longitudinal direction in the rail vehicle enables an opening in transverse movement. In a rail vehicle, a plurality of movable fastening devices with axes of rotation in the longitudinal direction can thus be positioned next to one another in the longitudinal direction in a simple manner. Several movable fastening devices, which are arranged next to one another in the longitudinal direction, can in particular be opened and easily accessible at the same time. This is advantageous in terms of accessibility.

A course of the axis of rotation or one axis of rotation of the plurality of axes of rotation in the transverse direction in the rail vehicle enables an opening in longitudinal movement. This embodiment is particularly advantageous because relatively long movable fasteners can be used. For example, you can lie in the second position, for example, vertically or at an angle in a corridor that is between the rows of seats is arranged within a passenger compartment of the rail vehicle.

In one embodiment of the arrangement according to the invention, the movable fastening device (13; 43) is connected to a safety cable or a damper which prevents an uncontrolled movement from the first position to the second position.

The safety cable can also be connected to a stationary part of the arrangement or of the rail vehicle. In particular, the catch cable can be arranged in such a way that a small pivoting movement, starting from the first position, is made possible until the catch cable is tensioned and prevents a further pivoting movement. The safety cable can then be removable, in particular at least at one end. A further pivoting movement up to the second position is only then possible in a controlled manner.

In particular, the damper can be configured to slow down the pivoting movement from the first position to the second position.

The catch cable and/or the damper increases/increases the operational safety of the arrangement, for example during maintenance work, and avoids/avoids damage to the arrangement due to uncontrolled movements.

Furthermore, a rail vehicle that has the arrangement according to the invention is proposed. The rail vehicle can in particular be a railcar or a non-powered car of a high-speed train. However, it can also be any other variant or type of rail vehicle, for example a railcar or a non-powered car of a long-distance train and/or a regional train and/or a local public transport train (e.g. subway, suburban railway, tram ).

The mentioned advantages of the arrangement according to the invention apply accordingly to the rail vehicle. This relates in particular to the improved use of space, the easy accessibility of the technical components and other technical components, the possibility of equipping the movable fastening device with other technical components before installation and thus prefabricating it as a module, the facilitation of maintenance, replacement and coordination work as well as the possibility of customized cooling.

Furthermore, a method is presented for equipping a rail vehicle or a car body with an arrangement according to the invention, having:

• Provision of the rail vehicle or the car body;
• Fastening other technical components to a movable fastening device;
• Installation of the moveable fastening device in the roof area of the rail vehicle or the car body.

The method can in particular be a method for retrofitting a rail vehicle with an arrangement according to the invention. Alternatively, the method can represent a partial step in the manufacture of the rail vehicle.

The order of the steps is arbitrary, as far as technically possible. The step of preparing the rail vehicle or the car body can take place before or after the step of fastening the further technical components to the movable fastening device. This means that the movable fastening device can be in the form of a prefabricated module with other technical components that have already been preassembled.

The further technical components can be attached to the movable fastening device before or after the assembly of the movable fastening device in the roof area of the rail vehicle or the car body. This means that further technical components can also be fastened when the movable fastening device is already installed.

An additional step of establishing an electrical and/or data-related and/or hydraulic and/or pneumatic connection between the other technical components and the rail vehicle and/or other technical equipment on the car body is generally carried out after the movable fastening device has been installed in the roof area of the rail vehicle and/or the car body and after the attachment of the other technical components to the movable attachment device. However, exceptions cannot be ruled out.

With regard to possible configurations of the method, reference is made in full to the configurations presented of the arrangement according to the invention and the rail vehicle according to the invention and to the advantages mentioned in each case.

The movable fastening device presented in relation to the method can be the movable fastening device presented in relation to the arrangement. Stationary fastening devices can already be present in the rail vehicle or the car body. It may be the stationary attachment devices that have been presented in relation to the arrangement.
