<p>The invention primarily relates to a locking device (1) for an actuator (13a, 13b, 13c), characterized in that it comprises a stationary crown (2) having an inner wall (2a), a wheel (8) rotatable relative to the crown (2), a bearing part (7) rigidly connected to the wheel (8), a hub (3) comprising at least one housing (10) formed on the outer wall (3b) of the hub (3) across from the inner wall (2a) of the crown (2), at least one locking member (5a, 5b) situated in said at least one housing (10) of the hub (3) and at least one elastic return member (6a, 6b) supported by the hub (3) and rigidly connected to said at least one locking member (5a, 5b), said at least one locking member (5a, 5b) being situated between the bearing part (7) and said at least one elastic return member (6a, 6b), said at least one elastic return member (6a, 6b) being able, in the absence of rotation of the wheel (8), to relax to allow locking of the hub (3) through jamming effect of said at least one locking member (5a, 5b) between said at least one housing (10) and the inner wall (2a) of the crown (2) and able, during the rotation of the wheel (8), to compress under the effect of the pressure exerted by the bearing part (7) on said at least one locking member (5a, 5b) so as to overcome the jamming effect and allow rotational driving of the hub (3).</p> |
