Patent ID: 7991530

Claim:
A system for classifying a vehicle occupant comprising: a base installed in each of leg frames of a seat of a vehicle; a cover installed above the base to be spaced apart from the base with a predetermined distance; a first weight sensor and a second weight sensor installed between the base and the cover to support the cover, and configured to measure a load transmitted to the cover by a weight of a vehicle occupant sitting in the seat; and a control unit configured to receive load values measured by the first and second weight sensors, and determine whether the vehicle occupant sitting in the seat is an adult or a child based on the received load values; wherein the control unit calculates the weight of the vehicle occupant by multiplying a two-sensor measurement load value set with an optimal independent variable set (X1.sub.k, X2.sub.k) where the optimal independent variable set (X1.sub.k, X2.sub.k) is a variable set that for various types of adult and child dummies, belongs to variable set within a range of a predetermined rational value, by which the two-sensor measurement load value set is multiplied, and maximizes a difference between a minimum weight value of the adult dummies and a maximum weight value of the child dummies.
