Abstract

본 발명은 자동차용 시트 벨트의 에너지 흡수 장치에 관한 것으로, 차량의 센터필러하부 도어 패널(미도시)의 하단부에 시트벨트의 벨트(31)선단부에 결합된 앵커 플레이트(32)가 로워 앵커 보울트(20)를 통해 고정되어 있되, 상기 앵커 플레이트(32)에는 상기 로워 앵커 보울트(20)가 통과되는 장공형상의 체결공(32a)이 형성되어 있고, 이 체결공(32a)의 양측면에는 캠부(32b)가 형성되어, 차량충돌시 벨트(31)에 의한 구속력을 완화하여 가슴상해치를 효과적으로 줄일 수 있도록 한 것이다.The present invention relates to an energy absorbing device for a seat belt for an automobile, wherein an anchor plate (32) coupled to a front end of a belt (31) of a seat belt is provided at a lower end of a vehicle door (not shown) of a center pillar lower door anchor bolt ( It is fixed through 20, the anchor plate 32 is formed with a long hole-shaped fastening hole 32a through which the lower anchor bolt 20 passes, and cam portions 32b on both sides of the fastening hole 32a. ) Is formed to reduce the restraint force by the belt 31 when the vehicle crashes to effectively reduce the upper chest hatch.
