APPARATUS AND METHOD FOR DETERMINING SEAT OCCUPANCY
First Claim
1. An apparatus for determining a seat occupancy comprising:
- a load detecting portion attached to a seat portion of a seat for a vehicle and detecting a seat occupancy load, applied to the seat portion;
a seatbelt buckling detecting portion detecting an engagement of a buckle of a seatbelt, provided for the seat for the vehicle; and
a seat occupancy determining portion determining the seat occupancy of the seat for the vehicle on the basis of detection signals from the seatbelt buckling detecting portion and the load detecting portion,the seat occupancy determining portion determining a mounted state of a child seat, in which the child seat is placed on the seat for the vehicle and is fixed thereto by means of the seatbelt, in a case where the seat occupancy load changes so as to be increased at a predetermined speed or faster and subsequently so as to be decreased at a predetermined speed or faster, within a time period proximate to a time point when the buckle is engaged.

Abstract
An apparatus for determining a seat occupancy includes a load detecting portion attached to a seat portion of a seat for a vehicle and detecting a seat occupancy load, a seatbelt buckling detecting portion detecting an engagement of a buckle of a seatbelt, and a seat occupancy determining portion determining the seat occupancy on the basis of detection signals from the seatbelt buckling detecting portion and the load detecting portion. The seat occupancy determining portion determines a mounted state of a child seat, in which the child seat is placed on the seat and is fixed thereto by means of the seatbelt, in a case where the seat occupancy load changes so as to be increased at a predetermined speed or faster and subsequently so as to be decreased at a predetermined speed or faster, within a time period proximate to a time point when the buckle is engaged.

19. A method for determining a seat occupancy comprising:
-
detecting a load, applied to a seat portion of a seat for a vehicle; detecting an engagement state or a disengaged state of a buckle of a seatbelt, provided at the seat for the vehicle; and determining a mounted state of a child seat, in which the child seat is placed on the seat for the vehicle and is fixed thereto by means of the seatbelt, in a case where the load changes so as to be increased at a predetermined speed or faster and subsequently so as to be decreased at a predetermined speed or faster within a time period proximate to a time point where the engagement state of the buckle is detected.
