SEAT CONDITION DETECTING DEVICE, IRRADIATING DIRECTION CONDITIONER OF HEAD LAMP ON VEHICLE AND SEATING DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a seat condition detecting device, a head lamp irradiation direction conditioner adjusting device on vehicle, and a seating detection device capable of detecting suitably short circuit anomaly of the power line feeding to a sensor body.

SOLUTION: The seating detection device 10 is equipped with the sensor body 10a deploying dispersively a plurality of parallel-connected pressure switch sections 11 with on-off switching in answer to the pressure on sitting sheets and identifies passenger's seating from at least one on-state of a plurality of the pressure switch section 11. The sensor body 10a is equipped with a shunt detecting resistor 12 connected in series with a plurality of pressure switch sections 11 connected in parallel.
