VEHICLE SENSOR DEVICE AND SEAT BELT RETRACTOR EMPLOYING SAME

A vehicle sensor device comprising a weight body housing installed in a body so as to be rotatable around a shaft coupled to the body, a weight body being installed in the weight body housing ball assembly for sensing a change in inclination of a vehicle, a sensor housing in which the ball assembly is movably installed, and a sensor lever installed in the sensor housing and rotated by the movement of the ball assembly. The sensor lever is configured to linearly reciprocate, by rotation, a pilot lever provided in a locking device. The sensor lever is installed in the sensor housing to which the ball assembly is coupled. The sensor lever is rotated around a hinge shaft by the movement of the ball assembly according to a change in inclination of the vehicle to linearly reciprocate the pilot lever connected to the sensor lever.
