[0003] Passenger vehicles include carriages that include one or more compartments adapted to transport passengers. These compartments particularly include, for example, seats arranged in rows.

[0004] Traditionally, a compartment adapted to transport passengers includes a ventilation system that may include a system for heating and / or cooling air so as to enable the air to be diffused in the compartment at an appropriate temperature and, more generally, to ensure air circulation in the compartment, the air circulation including the movement, diffusion, and guidance of air in an air flow according to the air flow. Such a ventilation system particularly includes one or more ventilation duct casings (gaine de ventilation).

[0005] Various ventilation systems are known for passenger vehicles, in particular railway passenger vehicles.

[0006] The ventilation system should be maintained regularly, in particular cleaned to ensure the quality of the diffused air, and also maintained to ensure its operation (replacement of parts, etc.).

[0007] For example, there are trains equipped with a ventilation system located under the passenger seats, the ventilation system being adapted to diffuse air into the interior of the compartment according to an upward flowing air current. Such a system is not very practical for maintenance because the seats or parts of the seats must be disassembled to access the ventilation system.

DETAILED DESCRIPTION

[0023] The invention will be described more specifically with reference to Figures 1 to 3 its application in a passenger railway vehicle (such as a train or a subway).

[0024] Figure 1 Schematically shows a part of a compartment 2 for transporting passengers of a train (not shown).

[0025] Compartment 2 includes seats 4 for passengers 6, the seats being arranged, for example, in rows, and each row including at least two seats 4 arranged side by side.

[0026] Compartment 2 forms part of a carriage 8 of a rail vehicle, the carriage 8 including an outer wall 10.

[0027] At least one glazed window 12 is fixed to the outer wall 10 to allow daylight to penetrate and enable the passengers 6 to see the scenery outside the vehicle.

[0028] Compartment 2 includes, for each glazed window 12, for example, a blind 14 adapted to be wound up around a drum (or reel) 16, the drum 16 being placed near the headrest 18 of a seat 4 located on the side of the glazed window (traditionally, in a train, a glazed window is placed, called a "window").

[0029] Compartment 2 also includes a soffit wedge 20 located above the seats 4, which is fixed, for example, to the ceiling member 22 of the compartment 2.

[0030] The soffit wedge 20 serves as a fixed support for various components of the compartment 2, such as a "coat rack" shelf 24 located above the seats 4, especially above the seats on the "window" side.

[0031] In Figure 1 the embodiment, compartment 2 includes a ventilation system 25, the ventilation duct hood 26 of which is arranged between the ceiling 22 and the soffit wedge 20.

[0032] The ventilation system 25 includes other components, so as to, for example, enable air to be directed to the ventilation duct hood 26, heat and / or cool the air, which is known and will not be described in detail here.

[0033] The ventilation duct hood 26 enables air (such as outside air, heated or cooled if necessary) to be diffused towards the interior of the passenger compartment 2. For example, the air is diffused towards the glazed window 12 according to Figure 1 the arrows shown.

[0034] In addition, the ventilation duct hood 26 also enables the air flow entering the hood from the interior of the compartment 2 to circulate, thereby forming an air flow for renewing the air in the passenger compartment 2.

[0035] In Figure 1 the embodiment shown, the soffit wedge 20 includes a loudspeaker 28, which is preferably arranged near the headrest 18 of the seat 4, so as to enable announcements to be broadcast in the compartment 2.

[0036] The ventilation system 25 also includes one or more air diffusion grilles 30. A single air diffusion grille 30 will be described in more detail below with reference to Figure 2 and Figure 3 more specifically.

[0037] The air diffusion grille 30 is advantageously mounted on a pivotable hinge 32 so as to be movable between a closed position, an open position and a decoupled position, in which the grille 30 is decoupled (or unhinged) from the hinge 32.

[0038] In one embodiment, the rail vehicle is a double-decker vehicle, and each carriage 8 includes two passenger compartments 2 stacked on top of each other, a lower compartment and an upper compartment.

[0039] Reference Figure 2 and Figure 3 The air diffusion grille 30 mounted on the pivotable hinge 32 is described in more detail.

[0040] The air diffusion grille 30 includes a first part 34 and a second part 38 having vanes 36.

[0041] The vanes 36 enable the air from the air duct hood 26 of the ventilation system 25 to be diffused towards the glass window 12.

[0042] In one embodiment, the first part 34 and the second part 38 of the air diffusion grille 30 are connected by a flexible joint.

[0043] For example, the flexible joint is a sealed joint, preferably made of rubber, such as made of EPDM (ethylene-propylene-diene monomer) rubber.

[0044] Preferably, the first part 34 and the second part 38 of the air diffusion grille 30 are incorporated in an aluminum profile.

[0045] The air diffusion grille 30 is fixed to the pivotable hinge 32.

[0046] Preferably, the pivotable hinge 32 is of the piano hinge type.

[0047] In one embodiment, the ventilation system 25 further includes one or more extensions 42 of the air duct hood 26, so as to enable the air flow to be directed towards the air diffusion grille 30.

[0048] Figure 3 Several positions of the air diffusion grille 30 are shown.

[0049] In fact, the air diffusion grille 30 is adapted to pivot between a first closed position POS1, a second open position POS2 and a third decoupled position POS3 due to being mounted on the hinge 32.

[0050] The closed position POS1 is the position of the air diffusion grille 30 when the compartment 2 is used to transport passengers. POS1 is the position where the second part 38 of the air diffusion grille 30 is at an angle α1 with respect to the horizontal axis A. This closed position enables the air flow to circulate from the air intake duct cover 26 to the interior of the compartment 2 and from the interior of the compartment to the air intake duct cover 26, as described above. The angle α1 is, for example, less than 60°.

[0051] In the open position POS2, the second part 38 of the air diffusion grille 30 is placed substantially vertically (the angle α2 is between, for example, 80° and 100°), which leaves an opening space 44, enabling the parts of the ventilation system, in particular the air intake duct cover 26, to be cleaned. This opening space 44 also enables access to other components of the compartment 2, such as the reel 16 of the curtain, for maintenance if necessary.

[0052] Finally, when the air diffusion grille 30 rotates about the hinge 32 such that the angle α3 between the horizontal axis A and the second part 38 of the air diffusion grille 30 is greater than 100°, for example equal to 150°, the air diffusion grille 30 is unhinged. Advantageously, it facilitates access to other components of the compartment 2, such as another air diffusion duct cover 46, which is a subordinate air diffusion duct cover with respect to the air diffusion duct cover 26 (main duct cover).

[0053] Advantageously, it facilitates the cleaning and maintenance of the ventilation system and other components of the compartment.

[0054] Advantageously, according to the present invention, the air intake duct covers 26, 46 can be cleaned without removing the seats.
