Description

Title of the invention: Passenger transport vehicle with variable number of seats

[0001] The present invention relates in general to a passenger transport vehicle, and in particular to a passenger transport vehicle equipped with a space management system inside the vehicle which makes it possible to adapt the space available between seated passengers and standing passengers according to the actual service conditions, and especially the density or quantity of passengers transported during the different moments of the service.

[0002] It is well known that means of passenger transport, such as trains, subways and buses, are increasingly used throughout the world.

[0003] As a result, particularly in certain areas, such as in large urban centres, the vehicles or convoys used are very congested for at least some part of their service, and especially during peak hours.

[0004] Since the vehicles used today have a predetermined capacity and a generally predefined configuration of their interior space, the result is that comfort on board the vehicle is not optimal, neither during peak hours nor during off-peak hours.

[0005] Indeed, the number of seats available and their positioning is generally predefined and during peak hours most passengers must therefore remain standing; on the other hand, during off-peak hours, it is also possible for passengers to remain standing, even if there is plenty of space available inside the vehicle.

[0006] Therefore, a main object of the present invention is to provide a solution offering improvements over the known state of the art, and especially to realize passenger transport vehicles where the exploitation of the space inside the vehicle can be optimized according to the different conditions of use during the service schedule, in particular according to the passenger traffic.

[0067] In particular, the or each first connection means 3 comprises an articulation, a possible embodiment of which is illustrated in [Fig.4].

[0068] In particular, this articulation is positioned between and is connected to the second end 32 of the corresponding second longitudinal bar 12 and to the second end 23 of the corresponding third longitudinal bar 13, and allows rotation around the axis of the articulation of each third longitudinal bar 13 relative to each corresponding second longitudinal bar 12.

[0069] Furthermore, the mechanical support structure 100 comprises second connection means 2 configured to connect the second end 22 of the or each second longitudinal bar 12 to the first end 21 of the or each corresponding first longitudinal bar 11.

[0077] According to a possible embodiment, as illustrated in Figures 3 and 7 to 9, the mechanical support structure 100 further comprises at least one fifth longitudinal bar 16 and fourth connection means 6 which are configured to connect a first end 26 of the fifth longitudinal bar 6 to the first longitudinal bar 11, close to the second end 31 of this first longitudinal bar 11.

[0078] Preferably, the mechanical support structure 100 comprises a plurality of fifth longitudinal bars 16, i.e. at least two longitudinal bars 16, and a plurality of fourth connection means 6 which are configured to connect a first end 26 of each fifth longitudinal bar 6 to a corresponding first longitudinal bar 11, close to the second end 31 of this corresponding first longitudinal bar 11.

[0079] In particular, a free space 37 is formed between the or each fifth longitudinal bar 16 and the or each first longitudinal bar 11 to accommodate at least a portion of the movable part 105 when the movable part 105 is in the second position B.

[0080] According to a possible embodiment, the fourth connection means 6 are configured to allow rotation of each fifth longitudinal bar 16 around the transverse axis 10 relative to the corresponding first longitudinal bar 11.

[0081] In particular, each fourth connection means 6 comprises a joint connected to the first end 26 of the corresponding fifth longitudinal bar 16 and to the corresponding first longitudinal bar 11. An exemplary embodiment of each connection means is illustrated in [Fig.4].

[0082] According to the embodiment illustrated in [Fig. 3], each fifth longitudinal bar 16 is connected to a corresponding first longitudinal bar 11, its second end 36 being free and suspended in the air. Furthermore, at least one additional covering surface 155 is arranged on and is connected to at least two of the fifth longitudinal bars 16, and is configured to form at least one backrest for the passengers.

[0083] According to the embodiment illustrated in Figures 7 to 11, each fifth longitudinal bar 16 is arranged so that its second end 36 is provided to bear on a body of the corresponding third longitudinal bar 13 when the movable part 105 is in the first position A, and is provided to slide on the body of and relative to the corresponding third longitudinal bar 13 when the movable part 105 is moved between the first position A and the second position B, as illustrated by the positions illustrated in sequence in Figures 7 to 9.

[0084] In this embodiment, an additional covering surface 155 is also provided on and connected to at least two of the fifth longitudinal bars 16, and is configured to form at least one backrest for the passengers, as illustrated in [Fig. 10] where the movable part of the structure 100 is in the first position A forming seating places, and in [Fig. 11] where the structure 100 is in the second position B.

[0085] According to a possible embodiment of the vehicle 1 according to the invention, the space management system comprises at least one control device 200, shown schematically in Figures 1, 3 and 7 in the form of a box drawn in dotted lines, which is configured to generate at least one remote control signal Sc adapted to activate the modification of the number of seats available for the passengers, and in particular to activate, preferably substantially in real time, the movement of the mobile part 105 relative to the fixed part 106.

[0086] Preferably, the control device 200 is configured to generate the control signal Sc remotely relative to the position of the seats to be modified, i.e. far from the seats, and in particular where the passengers cannot activate it.

[0087] Preferably, the control device 200 is installed on board the vehicle 1, for example in the cockpit or cockpit of the vehicle 1, or in any position inaccessible to passengers, and is configured to activate the modification of the number of seats available for passengers, substantially in real time during the movement of the vehicle 1, in particular according to the actual conditions of passenger traffic.

[0088] For example, an operator on board the vehicle 1 can activate the modification of the number of seats available for passengers on the basis of his direct view or on the basis of images provided by video cameras. These video cameras can be mounted for example in the space intended to accommodate passengers and / or on the platforms of stations, and can monitor the actual density of passengers to be transported.

[0089] Furthermore, the management system used in the vehicle 1 according to the invention comprises actuating means shown schematically in FIGS. 1, 3 and 7 in the form of a dotted line box 5, which are configured to move the or each movable part 105 between the first position A and the second position B, as a function of the command signal Sc received and which has been emitted by the control device 200.

[0090] In particular, the actuation means 5 comprise at least one motor controlled remotely by the control device 200.

[0091] According to a possible embodiment, the or each remotely controlled motor is a linear motor which is mounted on a first longitudinal bar 11 and which slides, along the body of this first longitudinal bar 11, moving from substantially integral with the corresponding third longitudinal bar 13 and second longitudinal bar 12.

[0092] Preferably, the actuating means 5 comprise several remotely controlled motors, in particular two or more linear motors, each motor being mounted on a corresponding first longitudinal bar 11 and sliding, along the body of this corresponding first longitudinal bar 11, moving in a substantially integral manner with the third longitudinal bar 13 and the second longitudinal bar 12 associated with this first longitudinal bar 11.

[0093] It is clear from the foregoing description that the passenger transport vehicle 1 makes it possible to achieve the aim underlying the present invention because the space available inside the vehicle can be managed more efficiently compared to known solutions. Indeed, in the vehicle 1 according to the invention, the space inside the vehicle is used in an optimized manner either during off-peak hours or during peak hours of the service. In particular, the internal configuration of the vehicle can be adapted to the traffic in real time: when passenger traffic is flowing smoothly, the number of available seats is increased; on the contrary, when traffic is denser, these seats, individual or grouped for example in the form of benches, are retracted, freeing up all the space available so as to allow the greatest number of passengers to have standing space. In this configuration, the capacity gain is optimal..

[0094] These results are obtained with a solution that is relatively simple from a constructive point of view and very flexible to apply.

[0095] The vehicle 1 thus designed is susceptible to modifications and variations. For example, the movable covering surfaces which form the available seating places and / or the ischial support, may have the form of a sliding bench comprising a plurality of seating places or seats, placed side by side, as illustrated in Figures 5 to 6 and 10 to 11, or they may form individual seating places or ischial supports. It is possible to realize a combination with seats or seats in the form of benches or the like, and individual seating places or seats.Furthermore, the movable seating positions may be positioned along the central aisle of the vehicle 1 and / or along the sides; the control device 200 may be configured to selectively move a number of movable seating positions and not all at the same time; the bars used may have a different shape compared to the shapes illustrated in the figures; the connection position, for example of each second longitudinal bar 12 along the body of a corresponding first longitudinal bar 11, may be different; each fifth longitudinal bar 16 may be connected to a first longitudinal bar 11 in a fixed manner.

[0096] All fittings can also be replaced by technically equivalent elements.
