First Claim
Patent Images
1. Method for occupant position detection for a vehicle seat, which includes the following steps:
- a) the forces applied to the seat by the occupant are measured at several measurement locations in the seat,b) the measured values of said forces are correlated, andc) the measured and correlated values are compared to reference values, which are obtained by measuring the forces applied at said measurement locations when the occupant is in a nominal position on the vehicle seat.d) and the “
empty seat”
measurements are calibrated in order to monitor variations due to influential parameters.

Abstract
The method includes the following steps:
- a) the forces applied to the seat by the occupant are measured at several measurement locations (D, R, S, G) in the seat (1),
- b) the measured values of said forces are correlated, and
- c) the measured values are compared to reference values, which are obtained by measuring the forces applied at said measurement locations (D, R, S, G) when the occupant is in a nominal position on the vehicle seat (1),
- d) the “empty seat” measurements are calibrated in order to monitor variations due to influential parameters.
