Actuator and family of actuators for a seat and method of manufacturing such an actuator

Method of manufacturing an actuator intended for mounting on a seat, the actuator comprising, on the one hand, a body and a control element which can be moved relative to the body under the control of an actuating motor, and, on the other hand, a transducer disposed between the body and the control element, said transducer being suitable for providing a raw measurement value (Plue) representative of the current position of the control element relative to the body, wherein means for correcting said raw measurement value are integrated in the actuator, said correction means being suitable for defining a correction algorithm which is specific to said actuator and which is suitable for providing a corrected value (Pcorr) for the current position of the actuator on the basis of said raw measurement value (Plue), and in that it includes a phase during which the correction algorithm defined by said correction means is customised for the specific actuator before the actuator is mounted on the seat.
