Abstract:
A seat occupant sensor device for detecting whether or not an occupant is seated on a seat, comprising:a pressure sensitive switch that includes a pair of sensor portions and a connecting portion, each of the sensor portions being formed as an integration of a pair of opposed films and a spacer, one of films being provided with a plurality of spaced first electrodes which are electrically connected to each other by way of a first conductive path, the other film being provided with a plurality of spaced second electrodes which are electrically connected to each other by way of a second conductive path, the spacer being disposed between the pair of opposed films in such a manner that each of the first electrodes is maintained separate from the second electrodes when the seat is unoccupied, the first conductive path and the second conductive path extending into the connecting portion, the connecting portion being positioned, when in its free state, between the pair of sensor portions; a connector provided at a distal end of the connecting portion for connecting the first conductive path and the second conductive path to an external control device; and a block member positioned at a connecting region of the pressure sensitive switch at which a proximate end of the connecting portion is connected to each of the sensor portions to guide the connecting portion in a reversely extending manner.
