Abstract
A seat-occupant sensing device for a car seat is provided, such that a heater can be installed in the seat without deterioration of sitting comfort. A load sensor is mounted to a cushion frame of a car seat. The end of a flexible cushion support is linked with the load sensor. Because the flexible cushion support flexes when a person sits on the seat, the load sensor detects the moment when the person sits on the seat.
