This application claims priority to European Patent Application No. 19020716.7 filed Dec. 19, 2019, the disclosure of which is hereby incorporated by reference in its entirety.
The present invention generally relates to the field of interior arrangement of passenger railway vehicles. More specifically, the invention relates to a rail vehicle having an open passenger area equipped with an integrated arrangement of perch seat and table.
Perch seats are used in rail vehicles to provide additional temporary seating in a generally open space. Perch seats, typically installed along surrounding walls of the open passenger space, provide increased comfort and stability to passengers when compared to simply standing up. On rail vehicles travelling on long journeys, these open spaces are typically used as bars or rest areas which may be used by passengers to stretch legs and to engage in social conversations with fellow passengers.
European Patent no. 2851256 to Bombardier discloses a room divider for placing into the open space area of a rail vehicle and providing the convenience of perch seats. The room divider provides a small support surface for example for recharging a mobile phone. This support surface may be convenient for standing passengers, but it unfortunately cannot be easily reached by passengers seated in perch seats since the support surface is located behind them.
There is therefore a need for a passenger space in a rail vehicle which is convenient, comfortable and inviting for passengers to relax and/or engage in discussions with fellow passengers.
It is an object of the present invention to provide a passenger area of a rail vehicle equipped with a perch seat and table assembly that overcomes or mitigates one or more disadvantages of known passenger areas, or at least provides a useful alternative.
The invention provides the advantages of allowing passengers seated in perch seats to easily use a table and to conveniently engage in discussions with fellow passengers should they wish so. Moreover, a smooth transition between perch seats and a table minimizes risks for passengers of hurting themselves against the table in case of sudden acceleration or braking of the rail vehicle.
In accordance with an embodiment of the present invention, there is provided a rail vehicle comprising a passenger space having a wall, a first perch seat, a table and a first transition surface joining the table to the first perch seat. The first perch seat is installed within the passenger space along the wall. The first perch seat has a first seating surface. The table has a horizontal working surface which extends from the wall so that at least a portion, preferably a major portion, of the table extends in front of the first perch seat and of a passenger seated in the first perch seat. The first transition surface has a first seat edge coplanar with the first seating surface and a first table edge coplanar with the working surface of the table. The first transition surface provides a continuous surface between the first seat edge and the first table edge so as to provide a smooth transition between both edges, thereby creating such continuous surface from the first seating surface to the table working surface.
Optionally, the first transition surface may be tangent to the first seating surface at the first seat edge and tangent to the working surface at the first table edge.
Optionally, a back edge of the table may be substantially colinear with an upper edge of the first perch seat and a front edge of the table may be connected to a lower edge of the first perch seat by a first transition edge of the transition surface.
Preferably, the first seating surface is located predominantly below the working surface so that the table is at a convenient height for the seated passenger.
Typically, the first seating surface is installed at an angle from the wall comprised between 0 and 60 degrees. The working surface may adopt a trapezoidal shape.
Optionally, a second perch seat with a second seating surface may be provided on the opposite side of the table from the first perch seat with a second transition surface joining the table to the second perch seat. The second transition surface has a second seat edge coplanar with the second seating surface and a second table edge coplanar with the working surface. The second transition surface provides a continuous surface extending between the second seat edge and the second table edge, thereby creating such continuous surface from the second seating surface to the table working surface.
The second perch seat may be attached along the same wall and a second seating surface of the second perch seat is then coplanar with the first seating surface. Alternatively, the first perch seat may be installed on a longitudinal wall whereas the second perch seat may be installed along an inner wall.
The second transition surface may be tangent to the second seating surface at the second seat edge and tangent to the working surface at the second table edge.
Similarly to the first upper edge, the second upper edge may be substantially colinear with the back edge of the table. The front edge of the table may be connected to the second lower edge of the second perch seat by a second front transition edge of the second transition surface.
Similarly to the first seating surface, the second seating surface may be predominantly located below the working surface.
Typically, the second seating surface is also installed at an angle ranging between 0 and 60 degrees from the wall.
These and other features of the present invention will become more apparent from the following description in which reference is made to the appended drawings wherein:
The present invention relates to a passenger rail vehicle having an open space where passengers may stretch their legs and rest against perch seats while using conveniently placed tables.
To better accommodate passengers, the open passenger space 10 is provided with perch seat assembly 14 installed along at least one wall, be it a side wall 16 or an inner wall 18. The perch seat assembly 14 comprises at least one perch seat 20, at least one table 22 and at least one transition portion 24.
Each perch seat 20 provides a seating surface 26 that is typically at an angle between 0 and 60 degrees from the side wall 16, thereby providing mostly lateral, but also some vertical support to users. The perch seat 20 may be padded or not.
The table 22 is attached either to the side wall 16 or the inner wall 18. The table 22 is therefore adjacent to one or two perch seats 20. The table 22 is positioned above or substantially at the same height as an upper portion 28 of the perch seat 20 and extends away from the wall to which it is attached. So installed and designed, the table 22 is conveniently placed to be used by passengers leaning against the adjacent perch seats 20 since at least a portion of its horizontal working surface 29 extends in front of the adjacent perch seats 20. The table 22 may be shorter so as to extend mostly on the side of seated passengers, or it may be deeper so as to reach further in front of passengers. A back edge 30 of the table 22 is substantially aligned, or colinear, with an upper edge 32 of the perch seat 20. This is best shown in
The table 22 may adopt a trapezoidal shape where its front edge 34 is shorter than its back edge 30. The table 22 could also have a rounded front edge 34. The trapezoidal shape of the table 22 is best shown in
Considering that the rail vehicle 12 may move at high speed and that small or even larger jerking motions may occur during travelling, transition portions 24 join the table 22 to a respective one of the adjacent perch seats 20. If there are two perch seats 20, one on each side of the table 22, then there are two transition portions 24, one between each side of the table 22 and the adjacent perch seat 20 on the corresponding side of the table 22.
The transition portion 24 is designed so as to smooth out any sharp edge the table 22 could otherwise present. With its shape, the transition portion 24 presents a transition surface 35 that deflects passenger bodies so that they do not hurt themselves against the table 22. The transition portion 24 may be padded for further absorption capacity.
To provide this smooth transition between the table 22 and one adjacent perch seat 20, the transition portion 24 has a seat edge 36 coplanar with the seating surface 26 of one adjacent perch seat 20 as well as a table edge 38 coplanar with the working surface 29 of the table 22. The transition surface 35 provides a continuous surface between the seat edge 36 and the table edge 38 so as to provide a smooth transition between both edges. The seat edge 36 and the table edge 38 may be smoothed out by a fillet joining the adjacent surfaces. The transition surface 35 may be tangent to the seating surface 26 of the adjacent perch seat 20 at the seat edge 36 and may similarly be tangent to the working surface 29 of the adjacent table 22 at the table edge 38. This in fact allows extending such continuous smooth surface from the seating surface 26 to the table working surface 29 through the transition surface 35. With the transition portion 24, the front edge 34 of the table 22 may be connected to a lower edge 40 of the perch seat 20 by a transition edge 42 of the transition portion 24.
When two perch seats 20 are located one on each side of the table 22, the table 22 is typically symmetrical and so are the transition portions 24 with one another.
The present invention has been described with regard to preferred embodiments. The description as much as the drawings were intended to help the understanding of the invention, rather than to limit its scope. It will be apparent to one skilled in the art that various modifications may be made to the invention without departing from the scope of the invention as described herein, and such modifications are intended to be covered by the present description. The invention is defined by the claims that follow.
