Seating detector
First Claim
1. A seating detector, comprising:
- a plurality of load sensors provided at a seat for detecting partial loads applied to the seat;
a total load calculating means for calculating a total load by summing up the partial loads detected by the load sensors;
an occupant determining means for determining an occupant of the seat based on an comparison between the total load calculated by the total load calculating means and at least one of thresholds;
a detecting means for detecting fastened/unfastened conditions of the seat belt;
a judging means for judging whether or not the total load is in a predetermined range when it is detected by the detecting means that the unfastened condition of the seat belt is switched to the fastened condition, and a determination maintaining means for maintaining a determination of the occupant of the seat as a child restraint system when it is judged that the total load is in the predetermined range.

3. A seating detector, comprising:
-
a plurality of cells provided at a seating surface of a seat to be defined by a two-dimensional array including rows and columns for detecting partial loads applied to the seating surface of the seat;
a calculating means for calculating a number of the cells being “
on”
which indicating the number of the cells whose partial pressure exceeds a predetermined pressure;
an occupant determining means for determining an occupant of the seat based on an comparison between the number of the cells being “
on”
calculated by the calculating means and at least one of thresholds;
a detecting means for detecting fastened/unfastened conditions of the seat belt;
a judging means for judging whether or not the number of the cells being “
on”
is in a predetermined range when it is detected by the detecting means that the unfastened condition of the seat belt is switched to the fastened condition, anda determination maintaining means for maintaining a determination of the occupant of the seat as a child restraint system when it is judged that the number of the cells being “
on”
is in the predetermined range. - View Dependent Claims (6, 9, 13)
