[origin: FR2862679A1] The ladder has three parts (2-4) with longitudinal posts (6) and stairs, and foldable on each other via an articulation unit, where the widths of the stairs are equal to or greater than the widths of the posts. The stairs pass partly from same side (C1) of the posts in upper part end and pass partly from a side (C2) or side (C1) of the posts in a lower end part. The stairs are intercalated in a folded position. An independent claim is also included for an installation including foldable stairs.
