Description

[0022] The invention allows numerous embodiments. It is explained in greater detail with the help of the following FIGURE, in which an exemplary embodiment is depicted.

[0023] A rail vehicle for passenger transport is schematically depicted in partial cross section in the FIGURE. The rail vehicle comprises an entry door 1 for opening and closing an interior 11 of the rail vehicle which is arranged in a boarding area of the rail vehicle. Furthermore, it comprises a sealing web 3. The door 1 is movably configured between a closed and an open state. The sealing web 3 is likewise movably configured between a sealing and an open state.

[0024] Both the closed state of the door 1 and also the sealing state of the sealing web 3 are depicted with continuous lines, while the open state of the door 1 and the open state of the sealing web 3 are depicted with dotted lines.

[0025] In the sealing state, the sealing web 3 forms a sealing surface 12 for a seal 8 of the door 1, said sealing web sealing the closed door 1 in respect of the interior 11 of the vehicle. The seal 8 in this case is configured as a double-lip seal.

[0026] In order to seal the closed door 1 in respect of the interior 11 of the vehicle, the seal 8 is prestressed between the sealing surface 12 of the sealing web 3 and the door 1. The seal acts in a horizontal direction.

[0027] The sealing web 3 is arranged pivotably about the horizontal shaft 6 on the floor 2. In the open state, the sealing web 3 is folded in and recessed in the floor 2. In the sealing state, on the other hand, the sealing web 3 is folded out and projects from the floor 2. The same surface of the sealing web, which acts as a sealing surface 12 in the sealing state, in this case acts as the stepping surface 13 of the floor 2 in the open state. In accordance with this embodiment, the sealing web 3 is completely recessed in the floor 2 and ends flush therewith, so that the floor is barrier-free in the boarding area, at least in the area of the sealing web 3.

[0028] Apart from the seal 8 between the door 1 and the sealing web 3, a further seal 10 is provided in this case which acts in the sealing state of the sealing web 3 between the sealing web 3 and the floor 2 and is correspondingly arranged between the sealing web 3 and the floor 2 and prestressed. The seal 10 is arranged on the floor 2 in a positionally fixed manner. It is located, both in the sealing and also in the open state of the sealing web 3, at the same point viewed relatively to said sealing web.

[0029] The vehicle may comprise a door frame, against which the door is otherwise sealed, in particular against which the door is leaned and is prestressed where necessary with further seals inserted in between.

[0030] Furthermore, the rail vehicle in this exemplary embodiment comprises a stepping platform 4 for bridging a gap in a horizontal direction between the boarding area of the vehicle and a platform 9 that can be displaced linearly in a horizontal direction. In order to receive the stepping platform 4 in the body of the vehicle, the rail vehicle comprises a recess 14 which is arranged below the floor 2 in the boarding area of the rail vehicle. Moreover, a flap 5 is provided which is mounted pivotably about a horizontal shaft 7 on the floor 2 of the rail vehicle in such a manner that, in an inserted state of the stepping platform 4, the flap 5 closes the recess 14 for receiving the stepping platform 4 and that, in an extended state of the stepping platform 4, the flap 5 acts as a ramp between the floor 2 and the stepping platform 4.

[0031] In the inserted state, which is depicted by a dotted line, the flap 5 ends the body of the vehicle flush with the outer skin of the vehicle directly surrounding the flap 5.

[0032] The extended state is drawn with continuous lines. The flap 5 acts as a ramp for balancing the floor level of the floor of the vehicle and the stepping surface level of the stepping platform 4. In this case, the stepping platform 4 has, in addition, a wedge-shaped area on its front end facing the platform 9, in order to align the stepping surface level of the stepping platform 4 with the platform level. Again, everything is step-free.
