Abstract

본 발명은 자동차용 시트 벨트의 에너지 흡수 장치에 관한 것으로, 차량의 센터필러(미도시)의 하단부에 고정된 브라켓느(30)에 시트벨트의 벨트(31)를 감고 있는 리트렉트(23)가 보울트(13)를 통해 정착되어 있고, 상기 브라켓느(30)에는 상기 보울트(13)가 통과될수 있도록 체결공(31)이 형성되어 있되, 이 체결공(31)은 장공형상으로 되어 있고, 상기 체결공(31)의 양측면에는 소정거리를 두고 다수 개의 충격흡수공(32)이 형성되어, 차량충돌시 벨트(31)에 의한 구속력을 완화하여 가슴상해치를 효과적으로 줄일 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy absorbing device for a seat belt for a vehicle, and includes a retract (23) wound around a belt (31) of a seat belt on a bracket (30) fixed to a lower end of a center pillar (not shown) of a vehicle. Is fixed through the bolt 13, the bracket 30 has a fastening hole 31 is formed so that the bolt 13 can pass through, the fastening hole 31 is in the shape of a long hole, A plurality of shock absorbing holes 32 are formed at both sides of the fastening hole 31 at a predetermined distance, so as to effectively reduce the chest injury by alleviating the restraining force by the belt 31 when the vehicle crashes.
