SYSTEM AND METHOD FOR CLASSIFYING VEHICLE OCCUPANT
First Claim
1. 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.

Abstract
A system and method for classifying a vehicle occupant is disclosed. A base is installed in each of leg frames of a seat of a vehicle. A cover is installed above the base to be spaced apart from the base. Two weight sensors are installed between the base and the cover to support the cover, and configured to measure a load transmitted to the cover by the weight of a vehicle occupant sitting in the seat. A control unit receives load values measured by the weight sensors, and determines whether the vehicle occupant sitting in the seat is an adult or a child based on the received load values. A shock absorption member is interposed between the weight sensors and the base. A stopper is interposed between the base and the cover in order to limit a downward movement range of the cover in a case of overload.

9. A method of classifying a vehicle occupant sitting in a seat using a system for classifying a vehicle occupant using two weight sensors, the method comprising;
-
determining a weight of a vehicle occupant by multiplying two-sensor measurement load value set with an optimal independent variable set (X1k , X2k) and calculating the sum thereof; comparing the calculated weight value of the vehicle occupant with a preset threshold value; and determining whether the vehicle occupant is an adult or a child. - View Dependent Claims (10, 11, 12, 13, 14)
