1. A pivoting and sliding door device for arrangement in a door opening of a door frame of a rail vehicle, the device comprising:
at least one pivoting and sliding door, which has a door leaf which is movable relative to the door frame and is mounted on the door frame between a door leaf closed position and a door leaf open position such that the movement direction of the door leaf runs substantially horizontally during an opening process and during a closing process;
a door sill of the door frame having a tread which is inclined to the horizontal, for persons entering and alighting, and
a door seal device having a passive lower door seal which seals a gap between a lower edge of the door leaf and the tread,
wherein the lower door seal is fastened to the lower edge or in the region of the lower edge of the door leaf and seals by a sealing section against the inclined tread when the door leaf is in the closed position,
wherein the sealing section has at least one tubular first cavity which runs parallel to the lower edge of the door leaf and has a first undeformed cross-section when the door leaf is in the open position and a second cross-section, which is deformed in comparison with the first cross-section, when the door leaf is in the closed position,
wherein the movement of the door leaf during the closing process, the inclination of the tread relative to the horizontal, and the sealing section cooperate such that, starting from the door leaf open position in which the first undeformed cross-section of the at least one first cavity is present, at the end of a first section of the closing process of the door leaf the sealing section bears against the tread with a contact surface, and that during a second section of the closing process subsequent to the first section, then the sealing section remains substantially adhered to the tread with its contact surface and the door leaf moves further in the direction of the door closed position and, when the door leaf closed position is finally reached by the door leaf at the end of the second section of the closing process, the at least one first cavity adopts the second deformed cross-section.
