Seat occupant determining apparatus
First Claim
1. A seat occupant determining apparatus of a seat adapted to a vehicle, comprising:
- a first load detecting sensor provided at a right portion of the seat in a seat width direction and at a lower portion of the seat in a seat height direction in order to detect a part of a load acting on the seat and a second load detecting sensor provided at a left portion of the seat in the seat width direction and at a lower portion of the seat in the seat height direction in order to detect a part of the load acting on the seat, where the seat has a seat back and the seat width direction corresponds to a width direction of the seat back;
a third load detecting sensor provided so as to be distant from the first and second load detecting sensors in a front or a rear direction of the seat in order to detect a part of the load acting on the seat;
a right-left sum value calculating portion calculating a right-left sum value by adding a first load value detected by the first load detecting sensor and a second load value detected by the second load detecting sensor;
a threshold changing portion for changing an occupant determining threshold on the basis of a third load value detected by the third load detecting sensor; and
an occupant determining portion determining an occupant of the seat to be an adult when the right-left sum value is equal to or more than the occupant determining threshold and determining an occupant of the seat to be a child placed in a child seat that is fixed to the seat when the right-left sum value is less than the occupant determining threshold.

Abstract
A seat occupant determining apparatus includes a first load detecting sensor at a right of a seat, a second load detecting sensor at a left of the seat, a third load detecting sensor at a front or a rear of the first and second load detecting sensors, in order to detect a part of the load, respectively, a right-left sum value calculating portion calculating a right-left sum value, a threshold changing portion for changing an occupant determining threshold on the basis of the load value of the third load detecting sensor, and an occupant determining portion determining an occupant of the seat to be an adult when the right-left sum value is equal to or more than the occupant determining threshold and determining an occupant of the seat to be a child in a child seat when the right-left sum value is less than the occupant determining threshold.
