International ClassB60R 021/32Foreign Application Priority Data1997-01-13 JPAbstractA seating sensor is provided on a seat back part and/or a seat cushion part of a seat in use for a vehicle such as an automobile, and calculates physical conditions, such as a height and weight of an occupant, to judge whether the subject on the seat is a human or an object. On the basis of the results of such calculation and judgement, the operation of an air bag is controlled. The seating sensor includes a sensing element which is variable in its electric resistance in response to the pressure variation, and the pressing force is detected on the basis of the variation of the electric resistance value. | |
