Abstract

본 발명은 안전벨트의 장력조절기에 관한 것으로서, 보다 상세하게는 차량 충돌시 승객의 신체가 앞으로 이동하기 전에 안전벨트에 장력을 가해 주도록 안전벨트가 감겨지는 축의 일단부에 피니언기어를 설치하고 상기 피니언기어를 차량충돌 감지신호에 따라 작동되는 가스발생장치에 의해 직선 운동하는 랙기어로 회전시킴으로써 차량충돌시 승객의 신체와 안전벨트 사이의 틈을 없애주는 안전벨트의 장력조절기에 관한 것이다.The present invention relates to a tension controller of a seat belt, and more particularly, the pinion gear is installed at one end of an axis on which the seat belt is wound so as to apply tension to the seat belt before the body of the passenger moves forward in a vehicle crash. The present invention relates to a tension controller of a seat belt that eliminates a gap between a passenger's body and a seat belt when the vehicle is crashed by rotating the gear by a linear gear moving by a gas generator operated according to a vehicle collision detection signal.
