Abstract
A lockable actuator includes: a body; a screw for pivoting relative to the body; a nut engaged on the screw so as to move along the screw between an over-retracted first position and a deployed second position on opposite sides of a retracted third position; a sleeve constrained to rotate with the screw and slidably mounted thereon in order to be moved by the nut; and an obstacle secured to the sleeve and a pawl capable of passing collectively between an active state and an inactive state, the pawl and the obstacle being arranged in such a manner that the pawl in its active state can co-operate with the obstacle only after the nut has been moved through a predetermined distance from its third position towards its second position.
