DRIVE
September 5, 2001
The method involves using capacitors (2,3) in a seat back part and in a sitting part whose capacitances are influenced by an object. The capacitors are subjected to an alternating voltage, the time variation of their capacitances is determined and a table derived for object assessment. If both assessments of the object agree regarding the type of object an occupant protection device associated with the seat is suitably activated as required.
