Abstract

Railway vehicle car (12), comprising a floor (18), the floor (18) comprising: - at least one low platform (22) extending in a main plane, the low platform (22) being arranged opposite at least one door (16) of the car, and - two inclined floors (24) relative to the main plane each arranged on either side of the low platform (22). At least one passenger seat (20) is fixed on at least one of said inclined floors (24).

Description

Railway vehicle car, comprising seats fixed on inclined floors

The present invention relates to a railway vehicle car, comprising a floor, the floor comprising:

- at least one low platform extending in a main plane, the low platform being arranged facing at least one door of the car, and

- two floors inclined to the main plane, each arranged on either side of the low platform.

The floors of the railway vehicle car are generally flat. However, due to the presence of bogies below the floors, it is often necessary to provide flat floors at a high height to leave enough space under the car to accommodate the bogies.

This high floor height has several drawbacks. Indeed, because of the high height of the floor, it is often necessary to provide steps to access and / or circulate in the car, which has in particular disadvantages for travelers with reduced mobility. To compensate for this drawback, provision is generally made to lower the floor height of the zone located opposite a vehicle door in order to approach it as close as possible to the height of the platform and thus avoid the presence of high steps making difficult access to the rail vehicle, especially for a wheelchair.

However, the zone of reduced floor height is connected by steps or ramps to the other zones of the car, of standard height which is adapted to accommodate the bogies. In these areas, several seats are provided at the same height to accommodate passengers. Even in the case of an inclined ramp, however, access to certain seats must always be via a step. Document FR 2 928 601 describes for example such a type of floor arrangement.

These steps complicate movement inside the car and / or access to seats, especially for people with reduced mobility.

In addition, the vision of passengers seated near the center of the car is often blocked by the seats near the ends of the car, which prevents them from observing movements in the car. In addition, this can create an impression of discomfort or even a feeling of claustrophobia in some passengers.

One of the aims of the invention is to overcome these drawbacks by proposing a railway vehicle car allowing circulation in the car and easier access to the seats and ensuring increased comfort for the passengers of the car.

To this end, the invention relates to a railway vehicle car of the aforementioned type, in which at least one passenger seat is fixed on at least one of said inclined floors.

By fixing the seat directly on the inclined floor, the movement of a passenger in the car and its access to the seat is significantly facilitated. Indeed, it is no longer necessary to plan to walk in the car to allow access to the seats located on the different levels of the car, which simplifies the movement of passengers with reduced mobility in the car.

According to particular embodiments of the invention, the car also has one or more of the following characteristics, taken in isolation or according to any possible combination (s):

- the floor has no steps for the movement of passengers in the car and for access to the seat;

- the height of the low platform is less than 900 mm, advantageously less than 700 mm, relative to the rails on which said car is arranged;

- inclined floors have a slope less than or equal to 9%;

- the inclined floors each have a lower end connected to the lower platform, and an upper end extending substantially in line with a bogie;

- the car has a plurality of seats;

- each seat comprising a seat and a backrest, the seat height of the seats measured relative to the low platform progressively decreasing from the upper end to the lower end of the inclined floors;

- the seats fixed on one of the inclined floors are substantially symmetrical with the seats fixed on the other inclined floor relative to the low platform; and

- the seat is fixed by an inclined foot on the inclined floor, the inclined foot being parallel to the inclined floor and forms an angle with the seat of the seat so that the seat extends substantially parallel to the low platform.

The invention also relates to a rail vehicle comprising at least one car as described above.

Other characteristics and advantages of the invention will appear on reading the description which follows, given solely by way of example and made with reference to the appended drawings, in which:

- Figure 1 is a side view of a railway vehicle car according to the invention; and

- Figure 2 is a top view of the car of Figure 1.

In the following, the terms of orientation are understood to refer to the usual orientation frame of railway vehicles, represented in FIGS. 1 and 2, and in which there are:

- a longitudinal axis X, oriented from rear to front, according to the direction of travel of the car,

- a transverse axis Y, perpendicular to the longitudinal axis, oriented from right to left and forming with the X axis a longitudinal plane, which is substantially horizontal when the car is placed on rails extending horizontally, and

- an elevation axis Z, perpendicular to the longitudinal plane, oriented from bottom to top.

In the description, the height is measured relative to the rails on which a rail vehicle is intended to run in a direction extending along the elevation axis Z when the vehicle is placed on the rails.

Referring to Figure 1, a rail vehicle 10 comprises at least one car 12. According to an embodiment shown in Figure 1, the car 12 comprises at least two bogies 14, two transverse walls 15, at least one door 16 provided in a central area of the car 12, a floor 18 extending above the bogies 12, and at least one passenger seat 20 arranged inside the car 12.

The bogies 14 are specific to each car 12, and are not shared between two neighboring cars 12, that is to say that each car 12 rests on two bogies which are distinct from the bogies on which the other cars of the rail vehicle rest. .

According to the configuration shown in Figures 1 and 2, the car 12 has four doors 16, each transverse wall 15 being provided with two doors 16 symmetrical with respect to a longitudinal axis extending in the center of the car 12. As a variant, the car 12 has two doors 16, each transverse wall 15 being provided with a door 16.

The floor 18 closes the bottom of the car 12 and thus delimits part of the interior volume of the car 12, this volume also being closed by the transverse walls 15 and by a ceiling 21.

The floor 18 comprises a low platform 22, and two inclined floors 24. Each inclined floor 24 has a lower end 26 and an upper end 28 opposite the lower end 26, as will be described below.

The low platform 22 is substantially flat and extends in a main longitudinal plane. As can be seen in FIG. 1, the low platform 22 extends between the two bogies 14.

The low platform 22 is disposed opposite the doors 16. It has a height of less than 900 mm, advantageously less than 700 mm in order to facilitate access by travelers with reduced mobility to the car 12.

The presence of the low platform 22 eliminates the presence of access steps between door 16 and the platform to access the car 12. This configuration facilitates access to the interior volume of the car 12 for passengers with reduced mobility or for bulky objects, such as a cart or the like. Indeed, in the prior art, it is often necessary to deploy a ramp extending beforehand between a door and the platform in order to facilitate their access to the car 12.

According to another embodiment not shown in the figures, the rail vehicle comprises a plurality of bogies, the front and rear ends of two adjacent cars being carried by one of the bogies. This type of railway vehicle is said to be “articulated”.

The inclined floors 24 are arranged on either side of the low platform 22, as visible in FIG. 1.

The inclined floors 24 are inclined relative to the main longitudinal plane, that is to say that they form a non-zero angle with the main longitudinal plane. They have a constant slope less than or equal to 9%, advantageously less than 6% in order to facilitate in particular the movement of travelers with reduced mobility in the car 12 while avoiding having to provide significant efforts to travel on the slope.

Thanks to the presence of the inclined floors 24, the car 12 has no steps inside the car. This facilitates the movement of travelers with reduced mobility or of crew members moving a cart in the car 12. Indeed, for cars of the state of the art which have a low platform and the high platforms, it is necessary to have the steps between the low platform and the high platforms or steps between the inclined ramps and some of the seats located near the low platform or bogies.

The lower end 26 has a lower height than the upper end 28 of the inclined floors 24. The lower end 26 is connected to the low platform 22 so that each of the inclined floors 24 is connected to the low platform 22 in order to form the integral floor 18.

The bogies 14 are arranged opposite the upper end 28 of the inclined floors 24, as visible in FIG. 1, that is to say that the upper end 28 of each inclined floor 24 extends above d a bogie 14. The height of the upper end 28 is configured to leave sufficient space for the bogies 14, and to connect to the usual level of intercirculations placed above the couplings, while limiting the slope of the inclined floors 24 The height of the upper end 28 is greater than 1000 mm, and is for example substantially equal to 1150 mm.

The bogies 14 being arranged at the upper end 28 of the inclined floors 24, the low platform 22 can be lowered, as described above, and can accommodate the doors 16 in the center of the car 12 without being limited by the presence of the bogies 14. Thus, it is possible to lower the height of the doors 16 and to increase its width, compared to a positioning between the end 28 and the bogie 14.

Each seat 20 comprises a seat 29, a backrest 30, and an inclined leg 31 adapted to fix the seat 20 on the inclined floor 24.

As can be seen in FIG. 1, the seat of the seat 29 is substantially parallel to the main longitudinal plane and is not parallel to the inclined floors 24. This configuration makes it possible to avoid the inclination of the seat of the seat 29 relative to the main longitudinal plane, and therefore provides better comfort when the passenger is seated in seat 20.

The inclined leg 31 is parallel to the inclined floor 24 and forms an angle with the seat 29 of the seat 20 so that the seat 29 extends substantially parallel to the low platform 22, as described above.

According to the preferred embodiment shown in FIGS. 1 and 2, the car 12 has a plurality of seats 20.

The seats 20 being fixed on the inclined floors 24, the height of the seats 20 therefore follows the slope of the inclined floors 24, and gradually decreases from the upper end 28 to the lower end 26. This configuration allows a better view of the seated passengers near the upper end 28 towards the middle of the car 12 without being blocked by the seats near the lower end 26.

According to an advantageous embodiment shown in FIGS. 1 and 2, the seats 20 fixed on one of the inclined floors 24 are substantially symmetrical with the seats 20 fixed on the other inclined floor 24 relative to the low platform 22. The distance between two seats 20 is substantially equal to 860 mm.

As a variant, all the seats 20 fixed on the two inclined floors 24 have a single direction, and the distance between two seats 20 in this configuration is substantially equal to 1000 mm.

The seats 20 are arranged in transverse rows 32. The seats 20 in each transverse row 32 are for example four in number. Each transverse row 32 comprises two groups 34 of seats arranged on either side of an inclined longitudinal passage 36. Each group 34 comprises two seats 20 arranged side by side with respect to each other.

The direct fixing of the seats 20 on the inclined floors 24 eliminates the steps between the inclined longitudinal passage 36 and the seats 20, unlike the prior art where a step is present due to the different levels of the car 12 on which the seats 20 are fixed. This facilitates the movement of passengers with reduced mobility in the car 12.

Thanks to the invention described above, access for travelers with reduced mobility to car 12 and their movements inside car 12 are facilitated. In addition, the views of the passengers seated in the car 12, in particular those seated near the end of the car 12 are improved, and are no longer blocked by the seats near the middle of the car 12. Indeed, the passengers are now able to observe movement in most of the car 12, eliminating their impressions of being confined to a small space.
