Device for actuating a seat element

An assembly of seats comprising:

• at least two similar seats disposed side by side, each said seat comprising at least one movable element;
• and
• at least one actuation device mechanically associated with the at least one movable element of each said seat, each said actuation device including
• an actuator fitted with a transducer adapted so as to deliver a state information representative of a current position of the actuator as the actuator moves, and
• a control unit for controlling said actuator, said control unit being linked to said transducer so as to receive the state information representative of the current position of the actuator, the control unit including
• means for registering (a) a first reference state information delivered by the transducer of the actuator and representative of a position of the actuator for an identified reference position of the movable element, and (b) at least one additional reference state information representative of a position of the actuator for at least one predetermined target position of the movable element, the at least one additional reference state information being delivered by the transducer of the actuator,
• means for storing said first reference state information and the at least one additional reference state information, and
• means for driving the actuator so as to move the movable element towards the at least one predetermined target position of the movable element,
• whereby said control unit is adapted so as, when a movement of the movable element towards the at least one predetermined target position or the identified reference position is commanded, to activate the actuator until the current reference state information delivered by said transducer is equal to the selected one of said first or the at least one additional reference state information stored for the associated said movable element position selected.
