VEHICLE SENSOR DEVICE AND SEAT BELT RETRACTOR EMPLOYING SAME

Disclosed are a vehicle sensor device and a seat belt retractor equipped with the same. The vehicle sensor device includes a body that forms an external appearance, a cover coupled to an opened one surface of the body, a sensor housing rotatably installed in the body according to an installation angle of the body and an inclination of a backrest, a ball installed inside the sensor housing to sense changes in the inclination and acceleration of the vehicle, and a sensor lever disposed on an upper portion of the ball and having one end rotatably coupled to the sensor housing. The sensor lever linearly reciprocates a pilot lever provided in a locking device by a rotation action according to movement of the ball. The sensor lever is installed in the sensor housing where the ball is installed, and the sensor lever is rotated about a rotating shaft coupled to the sensor housing by the movement of the ball according to the change in inclination and acceleration of the vehicle to linearly reciprocate the pilot lever connected to the sensor lever, thereby allowing the pilot lever to be engaged with or disengaged from the locking device. Thus, the normal control range of the pilot lever can be extended.
