Seat occupant sensor device

A seat occupant sensor device for detecting whether or not an occupant is seated on a seat, comprising:

• a pressure sensitive switch comprised of a pair of films and a spacer positioned between the films, one of the films being provided with a first electrode connected to a first conductive path and the other film being provided with a second electrode connected to a second conductive path, the spacer being disposed between the pair of films in such a manner that the first electrode is separate from the second electrode when the seat is unoccupied, the pressure switch possessing a configuration defining spaced part sensor portions and a connecting portion, the first conductive path and the second conductive path extending into the connecting portion of the pressure sensitive switch, the sensor portions being connected to the connecting portion at a connecting region;
• a connector connected to 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 the connecting region of the pressure sensitive switch with at least a part of the connecting portion extending along the block member in a direction generally opposite the sensor portions.

A seat occupant sensor device for detecting whether or not an occupant is seated on a seat, comprising:

• a pressure sensitive switch comprised of a pair of sensor portions, a connecting portion and a connecting region at which the connecting portion is integrated with the sensor portions, each of the sensor portions being provided with at least one first electrode and at least one second electrode that are separated from one another when the seat is unoccupied and that contact one another when the seat is occupied, the first electrode of at least one sensor portion being connected to a first conductive path and the second electrode of at least one sensor portion being connected to a second conductive path, the first and second conductive paths extending into the connecting portion;
• and
• a connector connected to the first conductive path and the second conductive path for connecting the first and second conductive paths to an external control device;
• the connecting portion being bent back upon the connecting region and extending in a direction generally opposite the direction of extent of the sensor portions.
