Abstract
A movable footboard for a door of a rail vehicle comprises a footboard extendable below a tread strip at least substantially transversely to the direction of travel. To minimize the level difference between the footboard and the tread strip a pivot shaft extends at least substantially parallel to the direction of travel on at least one longitudinal bar of the footboard at the end region of the footboard away from the vehicle, about which pivot shaft at least two pivoting bars are pivotably supported, which pivoting bars each bear a transverse profile element, each of the pivoting bars being rigidly connected to the transverse profile element associated with the pivot bar, while the other transverse profile elements lie freely on said pivot bar, and a lifting mechanism is fastened to the vehicle and lifts the transverse profile element located directly in front of the tread strip.
