1. Method for occupant detection and classification for a vehicle seat, which seat has at least one displacement adjustment controlled by at least one displacement actuator, which includes the following steps:
- a) said actuator enabling the displacement of said seat is controlled by progressively increasing with time the power supplied to said actuator using a predetermined profile,b) the startup movement of the displacement actuator is detected, and the value of said power is recorded at that moment,c) said recorded power value is compared to a series of predetermined reference values in order to determine the presence of an occupant on the seat and classify him according to his weight.

Abstract
The seat has at least one displacement adjustment controlled by at least one actuator.
The method includes the following steps:
- a) said actuator enabling the displacement of said seat is controlled (400) by progressively increasing with time the power supplied (PA) to said actuator following a predetermined profile,
- b) the startup (DM) movement of the displacement actuator is detected, and the value of said power is recorded at that moment,
- c) said recorded power value is compared to a series of predetermined reference values in order to determine the presence of an occupant on the seat (1) and classify him according to his weight.

14. Device for occupant detection and classification for a vehicle seat, which seat has at least one displacement adjustment controlled by at least one displacement actuator, which includes:
-
a) means for applying a predefined power profile to said displacement actuator for said seat, with said power providing at least one characteristic representing the effort applied to the actuator. b) means for detecting the movement of said seat actuator, c) means for comparing said power value, defined at the moment said actuator moves, with a series of predetermined reference values for said power, in order to determine the presence of an occupant (or an object) on the seat and to classify it according to its weight. - View Dependent Claims (15, 16, 17, 18)
