Description
Rail vehicle for transporting passengers
The invention relates to a rail vehicle for passenger
transport, having a plurality of passenger seats which form a
seating arrangement and which are secured in the rail vehicle.
In rail traffic for passenger transport, in particular in
regional and local rail traffic, the use and type of use of the
rail vehicles, both over one day and over the seasons, is
subject to significant fluctuations.
On the one hand, the fluctuations are based on peak commuter
times in which a maximum number of passengers are intended to
be conveyed. An optimum inner space configuration of the rail
vehicle for these purposes are passenger compartments with
large standing space regions and, depending on the vehicle
contour, only few seats or none at all. A seasonal fluctuation
in use is based on the fact that, for example, in the summer,
or as a result of the weather, there is a demand for a
significantly increased carriage of bicycles in the vehicles.
An optimum inner space configuration for such purposes is a
mixture of bicycle storage regions which are free from seats
and seating regions.
Outside of these special instances of use, it is in the
interest of the passengers and consequently also the rail
operators to provide the greatest possible number of
comfortable seats.
For the purposes mentioned, it is known to provide so-called
multi-purpose regions in vehicles in which there are provided
passenger seats which can be folded away and which are
typically mounted on a side wall of the rail vehicle. It is

also possible to completely remove the seats but they then have
to be accommodated in storage spaces which have to be provided.

It is further known from DE 10 2009 004 987 Al for aircraft, in
the case of passenger seats, to fold the seat face thereof
against the rear face in order to then push the passenger seats
one into the other. During this procedure, the passenger seats
do not have to be disassembled, but can be pushed together in a
space-saving manner. However, it is perceived to be
disadvantageous that these seats still require a considerable
area which cannot be used in any other manner since it serves
to store the vehicle seats.
Based on this, an object of the invention is to develop a rail
vehicle of the type mentioned in the introduction in such a
manner that the seating arrangement of the vehicle inner space
can be changed rapidly based on fluctuations in use.
This object is achieved with the rail vehicle in that, for at
least one passenger seat, there are provided a guiding device
for moving the passenger seat in a vertical direction directly
below an inner ceiling of the rail vehicle and a securing
device for securing the passenger seat below the inner ceiling.
In this manner, it is possible to make completely available the
floor space which is occupied when the passenger seat is in use
for a different purpose. The free spatial region below the
inner ceiling is used as a "storage space" for the passenger
seat. In this instance, any relevant provisions relating to
required passageway heights of at least 1950 mm are intended to
be complied with.
The passenger seat may have a backrest and a seat face, the
backrest then being able to be folded onto the seat face of the
passenger seat. It is consequently possible to use complete
passenger seats which have a backrest for the seating

arrangement of the inner space of the rail vehicle. As a result
of the foldability of the passenger seat, space-saving storage
below the inner ceiling of the rail vehicle is possible.

In particular for passenger seats located in the central
portion of the inner space of the rail vehicle, the guiding
device can be constructed as a vertical retention rod. If
necessary, the passenger seat is pushed upward along the
retention rod below the ceiling. In this instance, the
retention rod may have at the upper end thereof catch means for
securing the passenger seat.
For passenger seats which are adjacent to the side wall of the
rail vehicle, it may be advantageous for the guiding device to
be constructed as a rail which is fitted vertically to a side
wall of the rail vehicle. The vehicle seat is pushed upward
vertically along the rail if necessary and secured directly
below the inner ceiling. This securing may preferably be
carried out in that the passenger seat can be clamped at the
upper end of the rail.
The passenger seat may be secured exclusively by means of the
guiding device. This would then apply both to the position of
use thereof over the floor of the rail vehicle and also to the
position thereof below the inner ceiling of the rail vehicle.
For both positions, suitable securing means are then intended
to be provided. However, it is not impossible for the vehicle
seat in the position for use thereof to be further fitted by
means of additional, releasable securing means which are
accessible from the inner space, for example, to the floor or
the side wall of the rail vehicle when an increased fixing
system appears to be required.
Embodiments of the invention are explained in greater detail
below with reference to the drawings. In this instance,

components which have the same action are indicated with the
same reference numerals. In the drawings:
Figure 1 is a view from above of a longitudinal portion of a
rail vehicle, which is provided with a seating arrangement,

Figure 2 is a side view of a portion of the longitudinal
portion of a rail vehicle of Figure 1 with vehicle seats in a
first position,
Figure 3 is a side view of a portion of the longitudinal
portion of Figure 1 with vehicle seats in a second position,
Figure 4 is a view in the longitudinal direction of the
longitudinal portion of Figure 1 with vehicle seats in a third
position, and
Figure 5 is a view in the longitudinal direction of the
longitudinal portion of Figure 1 with vehicle seats in a fourth
position.
In Figure 1, a portion of a seating arrangement of an inner
space of a rail vehicle is illustrated. A backrest 1 and a seat
face 2 form a vehicle seat 6. In the example of Figure 1, the
illustrated longitudinal portion of the rail vehicle shows a
total of 24 vehicle seats which are each arranged in pairs,
backrest 1 to backrest 1. External vehicle seats 6 adjoin a
side wall 7. At an inner side of the side wall 7, there are
provided vertically extending guide rails 4 on which the
external vehicle seats 6 are releasably secured in the position
for use thereof. Internal vehicle seats 6 are in contrast
releasably secured to vertically extending retention rods 5.
Both the guide rails 4 and the retention rods 5 serve to move
the vehicle seats 6 from a position for use over the floor of
the rail vehicle into a raised position below an inner ceiling
3 of the rail vehicle. In this context, it can be seen from
Figure 2 that the backrests 1, as indicated with arrows, can be
folded down in such a manner that they rest on the seat faces
2.

In Figure 3, centrally arranged vehicle seats 6 are already
arranged in the raised position below the inner ceiling 3. To
this end, they have been moved along the retention rod 5 or the
guide rail 4 vertically upward. In the case of use of one of
the retention rods 5, a catch means for securing the passenger
seat 6 is provided at the upper end thereof. If the guide rails
4 are used in order to move one of the passenger seats 6 into
the raised position, the passenger seat 6 may be able to be
clamped to the upper end of the guide rail 4 so that it
maintains its raised position. In Figure 3 at the right-hand
side, the folded-in position of the passenger seat 6 still in a
state close to the floor, an intermediate position and the
raised position are illustrated (the last two with dashed
lines).
Figures 4 and 5 show other possible arrangements of passenger
seats, some in the position for use, some in a raised position.
What they have in common is that provisions to be complied with
relating to a passageway height of at least 1950 mm are
intended to be complied with. Since each individual vehicle
seat 6 can be moved individually into the raised position, the
longitudinal portion of the rail vehicle as illustrated in
Figure 1 can be released in the manner required in order to
accommodate additional passengers or to accommodate bicycles by
an appropriate number and arrangement of passenger seats 6
being moved into the raised position.
