VEHICLE SENSOR DEVICE AND SEAT BELT RETRACTOR TO WHICH SAME IS APPLIED

WIPO Patent Application WO/2024/076026

A1

Provided are a vehicle sensor device and a seat belt retractor to which same is applied, the retractor comprising: a steering disc which is disposed at one side of a spindle, and which rotates according to the insertion or withdrawal of seat belt webbing; a bearing plate in which the steering disc is accommodated; a sensor housing provided to be rotatable on the basis of changes in the provision angle of the bearing plate and in the inclination of an object to be mounted; a ball moving in the sensor housing according to changes in the inclination and acceleration of a vehicle; an upper cover disposed above the ball, and disposed to be rotatable according to the movement of the ball; a pilot lever, which rotates by means of the rotation of the upper cover while coming in contact with the upper cover so as to be coupled to or separated from the steering disc; and a lock canceller lever, which releases contact between the steering disc and the pilot lever so as to rotate the steering disc, thereby enabling the seat belt webbing to be inserted and withdrawn, and thus the structure of the vehicle sensor device is simplified such that workability is improved during manufacturing and manufacturing costs can be reduced.
