차량 센서를 갖는 시트벨트 리트랙터에 관한 것으로, 차체에 연결되는 고정 프레임, 상기 고정 프레임에 설정된 방향으로 배치된 축을 기준으로 회전 가능하게 장착되고 시트벨트가 외감되는 스풀, 상기 스풀이 회전하는 축에 연결되어 함께 회전하며 외부 치형부를 갖는 제어 디스크, 관성체의 유동에 의해 자동차의 가속도 변화를 감지하여 상기 제어 디스크의 회전을 방지하는 차량 센서 유닛 및 상기 고정 프레임의 일측벽에 결합되는 하우징에 설치되는 설치부재를 포함하고, 상기 차량 센서 유닛은 상기 설치부재에 직접 회전 가능하게 결합되는 구성을 마련하여, 차량 센서 유닛을 설치하기 위한 부품 수를 줄여 조립 작업시 작업성을 향상시키고, 제조 비용을 절감할 수 있다.

    Disclosed is a seat belt retractor having a vehicle sensor. The seat belt retractor includes: a fixed frame connected to a vehicle body; a spool mounted on the fixed frame so as to be rotatable about a shaft arranged in a predetermined direction, in which a seat belt is wound around the spool; a control disc connected to the shaft about which the spool rotates to rotate together with the spool, and having external teeth; a vehicle sensor unit for detecting a change in acceleration of a vehicle by a fluctuation of an inertial member to prevent the control disc from rotating; and an installation member coupled to a housing which is coupled to one sidewall of the fixed frame, wherein the vehicle sensor unit is directly and rotatably coupled to the installation member. Accordingly, the number of components required for installing the vehicle sensor unit is reduced, so that workability is improved during an assembly work, and a manufacturing cost is reduced.
