摘要

The staircase (1) has steps (6) and side balustrades (7) connected to a mobile bearing structure (5). The bearing structure is mobile between a deployed position for utilization of the staircase and a folded position. The bearing structure with the steps and the balustrades protrudes from a guiding and supporting structure (8) and inclined towards bottom, when the staircase is in a deployed position. The bearing structure with the steps and the balustrades is reversed above the guiding and supporting structure and inclined towards top, when the staircase is in a folded position.
