Zusammenfassung:	A variable-pitch vane for a stator stage includes an active part of the vane either side of which are positioned a radially inner platform and a radially outer platform, where the active part of the vane, which has a surface forming a convex surface, and a surface forming a concave surface, separate the platform into a part positioned on the convex side and a part positioned on the concave side. Seen along the direction of the vane's axis of rotation, the part has an outer outline superimposed on a circle, at the distance of which, and inside which, is at least a part of the outer outline of the part of the platform.
