1. A method for determining the morphology of the occupant of an automotive car, characterized in that it comprises the steps of collecting ( 200 ) the outputs of a plurality of capacitive sensors ( 100 ) provided on a seat, determining for each capacitive sensors ( 100 ) a first value representative of the distance (di) separating a target ( 10 ) from the sensor ( 100 ) and a second value (Sdi) representative of the surface of the sensor ( 100 ) covered by the target ( 10 ), applying ( 210 ) to the second values (Sdi) representative of the surface of the sensor ( 100 ) covered by the target ( 10 ) a respective weighting (Wi) based on the corresponding first value (di) representative of the distance separating the target ( 10 ) from the same sensor ( 100 ), and determining ( 240 ) the morphology of the target ( 10 ) on the basis of the collection of weighted second values (SdixWi).
