Ramp comprising a lateral barrier

A sliding step of a door entry of a passenger transportation vehicle, comprising:

• a planar element, a front side, two side edges, and a rear side, the planar element being movable along said two side edges between a retracted position and an extended position;
• wherein the planar element, on its side edges, encompasses barriers, movable from a first upright position, in which they extend upwards in relation to a stepping surface of the planar element, into a second lowered position and vice versa, wherein the movement of the barriers is effected by further extending the planar element in a direction parallel to the side edges after the planar element is in the extended position;
• wherein each of the barriers encompass a barrier bar and at least one barrier arm, the barrier arm being supported on the planar element and on the barrier bar so as to be capable of being pivoted, so that the barrier can be erected and lowered;
• the barrier further encompassing a barrier rod, which at least in the first upright position, is in contact with a stationary component of the vehicle, the stationary component being arranged such that the barrier rod is already held on the stationary component in response to the extension of the planar element prior to reaching the end position of the planar element and that further extension movement of the planar element effects a movement of the barrier;
• and
• wherein the free end of the barrier rod encompasses a caster, which is guided in a barrier guide roll and that the stationary component is formed by means of an end stop of the barrier guide roll in an extension direction of the planar element, the stationary component being arranged below the bather guide roll and in contact with the bather rod from a side view of the sliding step.
