[0012] The invention will be better understood by reading the description that follows, given

Only by way of example and made in reference to the attached drawings, in which:

- Figure 1 is a schematic side view, taken in section according to a vertical and longitudinal plane of the railway vehicle, of the arrangement of the passenger compartment and access platforms according to the invention, and

40 - Figure 2 is a schematic view, taken in section in view from above according to a horizontal and transverse plane of the railway vehicle according to Figure 1.

[0013] Hereinafter, the term "longitudinal" is defined according to a direction that extends between the rear and the front of a railway vehicle. The term "transversal" is defined according to an address

45 perpendicular to the longitudinal direction. The cross direction corresponds to the direction of access to the railway vehicle.

[0014] With reference to Figures 1 and 2, a rail vehicle 1 is described on two floors, called lower and upper floor.

fifty

[0015] The rail vehicle 1 comprises a box 4, which delimits a lower passenger compartment 6 on the lower floor and an upper passenger compartment 8 on the upper floor, arranged one above the other.

[0016] On the lower floor, the rail vehicle 1 comprises a first level 10, which delimits the

lower passenger compartment and a second level 12 displaced in height with respect to said first level 10, which defines an access zone 20 for the users of the lower 6 and upper 8 passenger compartments.

[0017] The rail vehicle 1 comprises a first 22 and a second access door 24, arranged

respectively of a first side 26 and a second side 28 of the rail vehicle, opposite each other in the transverse direction. Preferably, the access doors 22, 24 are almost opposite each other. As a variant, the access doors 22, 24 are displaced in the longitudinal direction. The access doors 22, 24 each delimit an opening corresponding to the second level 12, towards the access zone 20.

5

[0018] The rail vehicle 1 also consists of a ladder 30 for access to the compartment of

upper passengers 8, which extends between the access area 20 of the lower floor and the upper passenger compartment 8 of the upper floor.

[0019] As illustrated in Figure 2, the rail vehicle 1 comprises a fixed ramp 32 that joins the area

of access 20 to the lower passenger compartment 6. Ramp 32 allows users in a wheelchair to circulate autonomously between the lower passenger compartment 6 and access area 20. Thus, ramp 32 is the preferred route of travel of wheelchair users.

[0020] On the other hand, the rail vehicle 1 comprises a bath module 38, preferably of

universal conception, arranged at the same level as the first level 10.

[0021] A bath module 38 from a universal conception is a standard module that can be equipped with a railway vehicle without modification. As a variant, the bathroom module 38 is the result of a version

20 customized.

[0022] In the example shown, the bath module 38 extends adjacent to the access zone 20, opposite the lower passenger compartment 6. As a variant, the bath module 38 is arranged anywhere else at the first level of the lower passenger compartment 6.

25

[0023] The bath module 38 comprises an appropriate presence sensor 42 to detect any user present in the bath module 38.

[0024] The lower passenger compartment 6 comprises, on the first level, a lower floor 44 and a removable track 30 for access to the bathroom module 38.

[0025] On the other hand, as illustrated in Figure 2, the access zone 20 extends between the first 22 and the second access door 24.

[0026] The access zone 20 comprises a first fixed access platform 48 located in front of the

first door 22 and on which this first door 22 ends, a second fixed access platform 50 located in front of the second door 24 and on which this second door 24 flows and a mobile access platform 52 interposed, in the transverse direction, between the first 48 and the second 50 fixed platform and intended to move vertically with respect to the fixed platforms 48, 50.

40

[0027] The first fixed platform 48 extends transversely from the first access door 22

up to the mobile platform 52 and has a dimension, in the transverse direction, sufficient to allow a wheelchair user to maneuver freely and autonomously.

[0028] The second fixed platform 50 extends transversely from the second access door 24

to the mobile platform 52.

[0029] Thus, the mobile platform 52 extends transversely between the first 48 and the second 50 fixed platform.

fifty

[0030] The dimensions of the mobile platform 52 are greater than those of a user's wheelchair. Advantageously, the transverse dimension of the mobile platform 52 is greater than 80 cm, preferably between 80 cm and 120 cm.

55 [0031] According to a variant not shown, in which the vehicle consists of a single fixed platform

on which the first access door 22 ends, the mobile platform 52 extends between this single fixed platform and the second access door 24.

[0032] The mobile platform 52 comprises a plateau 54 and a displacement mechanism 56 of this

plateau 54 with respect to box 4 of the railway vehicle.

[0033] The travel mechanism 56 moves the plateau 54 between a high position that reaches the first fixed platform 48 and a low position that reaches the lower floor 44 of the passenger compartment

5 lower 6.

[0034] The displacement mechanism 56 consists of a motorized organ 58 that moves the plateau 54 with respect to the box 4 and a manual maneuvering organ 60 independent of the motorized organ 58. The manual maneuvering organ 60 is capable of vertically displacing the Plateau 54 of the mobile platform without electricity. Be

10 uses for example in case of failure of the motorized organ 58.

[0035] The manual maneuvering organ 60 is a jack-type lifting apparatus. The lifting device is advantageously a hydraulic jack, a jack with pin and zipper, a jack with pin and worm, etc.

[0036] As a variant, the manual maneuvering organ 60 comprises any type of apparatus that allows

move the plateau 54 vertically with respect to the lower floor 44 manually.

[0037] The displacement mechanism 56 optionally comprises at least one position sensor 62 of the plateau 54 with respect to the box 4. The or each position sensor 62 is capable of detecting the plateau

20 54 of mobile platform 52 in low position and high position. The or each position sensor 62 is advantageously an electric sensor type sensor, mechanical limit switch sensor or any other type of detection sensor with or without contact.

[0038] In high position, the plateau 54 completes a spacing between the first 48 and the second 50 fixed platform 25. The plateau 54 then forms a path between the first 22 and second 24 access doors. Also, the plateau

54 in high shutter position in part the access to the bathroom module 38.

[0039] In low position, the plateau 54 releases a spacing between the first 48 and the second 50 fixed platform and defines an access road 46 between the lower floor 44 of the lower passenger compartment and the bathroom module

30 38. The second fixed platform 50 is then inaccessible to wheelchair users.

[0040] As a variant, the displacement mechanism 56 of the mobile platform ensures the function of a wheelchair user lift between the first level 10 and the second level 12.

[0041] According to the invention, the ramp 32 extends between the first fixed platform 48 of the second level

12 and the lower floor 44 of the first level 10.

[0042] Ramp 32 comprises, for example, an intermediate landing 63 and two inclined planes 64, 66 connecting for one, the first fixed platform 48 to the intermediate landing 63 and for the other, the intermediate landing

40 63 to the lower floor 44.

[0043] The transverse dimension of ramp 32 is advantageously greater than the volume of a wheelchair, preferably greater than 80 cm and advantageously between 80 and 120 cm.

[0044] Each inclined plane 64, 66 has an access slope sufficiently reduced to allow

access between the first and second level 10, 12 to wheelchair users autonomously. The inclination of the inclined planes is advantageously between 3 ° and 9 °.

[0045] As illustrated in Figure 2, at least one step 34 is disposed between the second fixed platform 50 50 and the lower floor 44. The step (s) 34 defines a circulation route attached to the pedestrian users who

They want to move between the first level 10 and the second level 12 during the use of the platform 52.

[0046] Thus, thanks to or to the steps 34, the passageway formed by the ramp 32 may be reserved for wheelchair users, the pedestrian users preferentially walking along the road annexed by the

55 steps 34. In other terms, the movement of wheelchair users does not hinder the movement of pedestrian users and vice versa.

[0047] As illustrated in Figure 2, the rail vehicle 1 consists of a mobile anti-tilt system 67, arranged between the first 10 and the second level 12 of the first floor. This anti-tilt system 67

It is intended to guarantee the safety of users, preventing the risks of broth between the first 10 and the second 12 level.

[0048] The anti-tilt system 67 comprises for example two portholes 68, 70, one interposed between the mobile platform 52 and the first fixed platform 48 and the other interposed between the mobile platform 52 and the second

fixed platform 50.

[0049] The anti-tilt system 67 also comprises a motorized articulation 72 that provides mobility to the two portholes 68, 70 between a first and a second configuration and a system of

10 mechanical coupling 74, which synchronizes the first and second configuration in the position of the mobile platform 52. More particularly, the coupling system 74 synchronizes the first configuration with the low position of the mobile platform 52 and the second configuration with the high position of the mobile platform 52.

[0050] Thus, the first configuration corresponds to the low position of the mobile platform 52. In this first configuration, the two portholes 68, 70 are interposed, one between the mobile platform 52 and the first fixed platform

48 and the other between the mobile platform 52 and the second fixed platform 50. The anti-tilt system 67 then prohibits access to the mobile platform 52 in a low position from the first 48 or second fixed platform 50.

[0051] The second configuration corresponds to the high position of the mobile platform 52. In this second configuration, the two portholes 68, 70 are interposed between the mobile platform 52 and the lower floor 44. The system

anti-tilt 67 then prevents a broth of a user from the mobile platform 52 in a high position towards the lower floor 44 of the first level.

[0052] The motorized articulation 72 that displaces the portholes 68, 70 is advantageously an electric gearmotor 25.

[0053] As a variant, the motorized joint 72 consists of any other type of mechanism that can rotate a gate.

[0054] The coupling system 74 is advantageously a belt pulley type transmission system. The

Pulleys are connected on the one hand to the displacement mechanism 56 of the plateau 54 of the mobile platform and on the other hand to the articulation 72 of the portholes 68, 70.

[0055] As a variant, the coupling system 74 consists of any other type of transmission chain 35 that synchronizes the displacements of the plateau 54 of the mobile platform with the articulation 72 of the gate.

[0056] The railway vehicle 1, on the other hand, comprises a control unit 76, which controls the position of the plateau 54 of the mobile platform and the use of the bath module 38.

[0057] The control unit 76 is connected on the one hand to the mobile platform position sensor 62 and

on the other hand to the user detection sensor 42 to the bathroom module.

[0058] The control unit 76 controls the position of the mobile platform 52 according to the travel conditions of the rail vehicle 1.

Four. Five

[0059] When the rail vehicle 1 arrives at the station stop, the control unit 76 drives the movement of the mobile platform 52 in the high position. On the other hand, during the journey, the control unit 76 drives the movement of the mobile platform 52 in a low position.

[0060] The control unit 76 simultaneously verifies the presence of the user in the bath module 38. The

Bathroom module 38 not occupied remains inaccessible to users during a stop at the station. In the presence of a user in the bath module 38, the control unit 76 waits for the user to exit to move the mobile platform 52 in a high position and to close the access to the bath module 38.

[0061] A first embodiment applied in a rail vehicle 1 will now be described.

[0062] Initially the railway vehicle 1 is in the station and authorizes the access to the users to the

lower 6 and upper 8 passenger compartments, through the access zone 20. The mobile platform 52 is in a high position. The anti-tilt system 62 is in the second configuration. Access to the bathroom module 38

is closed.

[0063] Users access rail vehicle 1 through the first 22 or second 24 access door of rail vehicle 1.

5

[0064] In the case of an access through the first door 22, the users arrive at the first fixed platform 48. The wheelchair users walk down the ramp 32 to reach the lower passenger compartment 6 to the first level.

10 [0065] In the case of an access through the second door 24, the users arrive at the second fixed platform 50.

Wheelchair users cross the mobile platform 52 in a high position, reach the first fixed platform 48 and walk along the ramp 32 to reach the lower passenger compartment 6.

[0066] Pedestrian users access the lower passenger compartment 6 by respectively walking 15 along the ramp 32 from the door 22 and the steps 34 from the door 24 between the first and second level 10, 12

from the first floor.

[0067] To reach the upper passenger compartment 8, pedestrian users walk down the stairs 30.

twenty

[0068] At the beginning of the route of the rail vehicle 1, the mobile platform 52 passes in a low position, in a synchronized manner the portholes 68, 70 of the anti-tilt system that pass in the first configuration.

[0069] The access road 46 for the bathroom module 38 is open. Users have access to the 25 bathroom module 38 by walking along the passage defined by the mobile platform 52 in the low position.

[0070] Before a stop at the station, the control unit 76 verifies the presence of users to the bath module 38 thanks to the presence sensor. When the bath module 38 is not occupied, the control unit 76 controls the closing of the bath module 38 and drives the movement of the mobile platform 52 in a high position. From

In a synchronized manner, the portholes 68, 70 of the anti-tilt system pass to the second configuration.

[0071] At the station, wheelchair users walk the reverse path. They reach the access zone 20 via the ramp 32. When the mobile platform 52 is in a high position, the wheelchair users indifferently access the first 22 or the second 24 access door.

35

[0072] Pedestrian and wheelchair user flows are distributed on each side 26, 28 of the rail vehicle. Wheelchair users walk along ramp 32. Pedestrian users walk indifferently along ramp 32 or steps 34 to reach access zone 20. Pedestrian users are distributed between the two vlas according to the influx.

40

[0073] In addition, when the displacement mechanism 56 of the mobile platform is defective, an operator piloting the railway vehicle 1 drives the manual maneuvering organ 60 which allows the plateau 54 of the mobile platform to be positioned in the desired position.

45 [0074] Railroad vehicle 1 on two floors guarantees access to wheelchair users until their

reserved location in the lower passenger compartment 6 autonomously and has a universal bath module 38 arranged at the same level of the first level 10 without modification of the upper compartment 8.

[0075] The fixed ramp 32 guarantees access to the lower passenger compartment 6 to users in a 50-wheelchair between the first level 10 and the second level 12 of the first floor, via the ramp 32. The ramp 32 returns

Directly accessible the first and second access doors 22, 24 thanks to the mobile platform 52 interposed.

[0076] The mobile platform 52 in a high position guarantees an interconnection between the first and second 55 access doors 22, 24 and adapts in a low position, an access road 46 to the bathroom module 38.

[0077] The railway vehicle 1 guarantees an optimized circulation of the users between the access doors 22, 24 and the lower passenger compartment 6. The railway vehicle 1 presents a first preferential route in the movement of the users in wheelchairs of autonomous way and a second route attached

for pedestrian users who can walk on steps 34. The arrangement of access roads allows the possibility of separating flows of pedestrian and wheelchair users to optimize access to the rail vehicle 1.

5 [0078] The rail vehicle 1 guarantees reliability in use by the fixed ramp 32 and on the other hand

by the maneuvering organ 60 of the mobile platform 52 manually in case of failure of the motorized organ 58.

[0079] It will be noted that the invention is not limited to the mode of embodiment just described, but could present several variants.

[0080] In particular, the railway vehicle could consist of only one floor.
