Seat occupation judging apparatus for a vehicle
First Claim
1. A seat occupation judging apparatus for a vehicle comprising:
- load detection means arranged at a seat for detecting a load on said seat to output a load detection signal;
seat condition detection means arranged at said seat for detecting a seat condition to generate a seat condition detection signal indicative of discrimination in presence on said seat between an adult and a child seat on said seat; and
judging means responsive to said load detection means and said seat condition detection means for outputting a judging signal indicating that a child seat is set on said seat when said load detection signal indicates that an adult sits on said seat and said seat condition detection signal indicates that said child seat sits on said seat.

Abstract
A seat occupation is judged with a load detector arranged at a seat for detecting a load on the seat and a seat condition detection means arranged at the seat for providing discrimination between an adult and a child seat on the seat. A judging means judges that a child seat is set on the seat when the load detection means detects the load corresponding to that of adult and the seat condition detection means detects that the child seat on the seat. The seat condition detection means may comprise an electrostatistic sensor for detecting a capacitance that is increased by the body of the passenger or a pressure detection element array arranged on the sitting portion. The detected capacitance or the pressure distribution is different between a child seat and an adult or a passenger.
