A door system (1) includes a door leaf (3) for closing off an entrance opening (4) and a suspension rod (10) having two opposite ends (11, 12) supported by a support structure (13). A suspension member (14) connects the door leaf (3) to the suspension rod (10) and can slide together with the door leaf (3) along the suspension rod (10) from an initial position corresponding to a closed position of the door leaf (3), to a final position corresponding to an open position of the door leaf (3). The two opposite ends (11, 12) of the suspension rod (10) are slidable in a horizontal direction transverse to the entrance opening (4). The suspension member (14) is slidably coupled to and guided by a non-linear upper guide (17) positioned above the suspension rod (10).

The handrail for getting on and off includes a rail portion for slidably holding one end portion of the link arm which expands and contracts with the movement of the slide door, and a handrail body configured to rotate integrally with the rail portion. When the slide door closes the entrance, the entrance handrail takes a retracted posture in which one end portion of the link arm is located at the other end portion of the rail part and the handrail body is arranged along the slide door. When the slide door opens the entrance, the entrance handrail takes a deployed posture in which one end portion of the link arm is positioned on one end portion side of the rail portion so that the rail portion and the handrail body protrude toward the outside of the vehicle.
