VEHICLE FOR TRANSPORTING PASSENGERS HAVING A VARIABLE NUMBER OF SEATS

A passenger transport vehicle includes a system configured to vary the number of available seating places in accordance with the level of passenger traffic to be transported. The system has a mechanical support structure having a fixed part and a movable part movable between a first position in which the mechanical support structure forms a seating place, and a second position in which the seating place is unavailable for seating. The mechanical support structure includes a covering surface connected to and disposed around a portion of the movable part. The covering surface includes two rigid portions and a deformable portion. One rigid portion forms a seating surface when the movable part is in the first position, while both rigid portions and the deformable portion form an ischiatic support surface when the movable part is in the second position.
