Abstract: A method for calibrating a device for actuating one or several elements to be actuated of a structure, with the actuating device comprising one or several actuators, characterised in that it comprises the following successive steps: (b1) placing the structure, in particular the element or elements to be actuated of the structure, in a predetermined reference position, (b2) activating a calculation unit to automatically calibrate the actuator or actuators of the actuating device, with the calculation unit able to determine, for the actuator or actuators, the minimum and maximum end stops that define its or their authorised range of movement using the predetermined reference position of the structure, taken as the origin position.

Abstract: A locking device for an actuator, characterized in that it comprises a stationary ring that has an inner wall, a movable wheel comprising a cavity formed on the outer wall of the wheel opposite the inner wall of the ring, an inertia locking member located in the cavity, a resilient drawback member exerting a force on the locking member, the latter able by the inertia thereof to overcome the force exerted by the resilient drawback member to allow for the locking of the wheel via a wedging effect of the locking member between the cavity and the inner wall of the ring.

Abstract: The invention relates to a control device for controlling an actuator for moving a mobile element of a seat in a vehicle. The control device comprises: a measuring device for determining a reference parameter relating to a passenger in the seat and/or to the state of the vehicle, and power-limiting means for defining a maximum limit for the power generated by the actuator in accordance with said parameter. The invention further relates to a seat or aircraft comprising the aforementioned device, and to a control method using said device.

Abstract: An electrical actuator for a seat with an inclinable back in which irreversibility (or blocking of the mechanism) and efficiency are independent of each other, efficiency being obtained by the use of a reduction gear with straight gear wheels (8), and irreversibility being obtained by a current release blocking device (7) mounted in parallel on an electric motor (5) and energized by the same control device (9) as the motor.
