A blade (1) having an outer covering (2) defining a cavity (8). A carriage (20) is arranged in said cavity (8), the carriage (20) being provided with a torsion bar (21) and at least two arms (22) secured to the torsion bar (21). The blade has one connection per arm provided both with an upstream guide gallery and with a downstream guide gallery, each arm extending transversely from an upstream end that slides in an upstream guide gallery to a downstream end that slides in a downstream guide gallery. At least one connection is a helical connection (40) obtained with the help of an upstream guide gallery (33) and the downstream guide gallery (34) of the segment (101) presenting distinct orientations, giving rise to movement in rotation (ROT1) of the segment (101) under the effect of the carriage (20) moving in translation.
