Abstract
A device is provided for unfurling and refurling comprising at least one tape spring having an axis of unfurling and of refurling parallel to an axis X and a rotor capable of rotating about an axis Y perpendicular to the axis X, the tape spring being able, autonomously, to pass from a state in which it is wound around the rotor to an unwound state. The tape spring is mounted bent in two in the shape of a U and comprises a first end fixed rigidly to a first anchor point that may be secured to a stator or to the rotor and a second end wound around the rotor.
