Abstract

본 발명은 시트벨트 어셈블리의 하단에 형성된 리트렉터의 일측에 고정되는 유성기어 어셈블리를 형성하고 그 외측으로 수풀과 연동되는 피니언을 고정하기 위한 몸체와 랙과 점화수단으로 이루어진 프리텐셔너를 장착한 것으로 급제동이나 충, 추돌시 발생하는 충격에 의한 벨트가 풀리는 것을 방지하여 운전자 및 탑승자를 안전하게 보호함과 동시에 제품의 소형화로 인한 공간 활용율을 극대화시킬 수 있도록 한 것으로서, 리트렉터(1)의 일측에 복수개의 구멍(1a)(1b)(1c)을 형성하여 고정 수단으로 유성기어 어셈블리(2)를 고정하고 그 외측으로 리트렉터(1)의 수풀(3)과 연동되는 피니언(4)을 고정하기 위한 몸체(5)를 형성하되, 상기, 몸체(5)의 일측에 랙(6)을 삽입하기 위한 가이드홈(5a)을 형성하며, 상기, 가이드홈(5a)의 하부로 랙(6)을 작동하기 위한 점화부(7)와 점화부(7)를 점화하기 위한 센서(8)로 형성되며, 상기, 유성기어 어셈블리(2)는 외측 고정기어(20)와 내측 유성기어(30)와 상기, 스풀(3)과 연동되는 선기어(40)를 형성하며, 내측의 유성기어(50)를 고정하는 캐리어(60)로 형성되고, 상기 캐리어(60)는 축이음 수단으로 상기, 피니언(4)고정되어 구성된 것을 특징으로 하는 시트벨트 어셈블리의 프리텐셔너이다.The present invention forms a planetary gear assembly that is fixed to one side of the retractor formed at the bottom of the seat belt assembly and is mounted with a pretensioner consisting of a body, a rack and an ignition means for fixing a pinion interlocking with the bush to the outside thereof. It prevents the belt from loosening due to the impact generated during collision and collision to protect the driver and passengers and to maximize the space utilization rate due to the miniaturization of the product.A plurality of holes on one side of the retractor 1 (1a) (1b) (1c) forms a body for fixing the planetary gear assembly (2) by the fixing means and fixing the pinion (4) interlocked with the bush (3) of the retractor (1) outside thereof ( 5) to form a guide groove (5a) for inserting the rack (6) on one side of the body (5), and for operating the rack (6) to the lower portion of the guide groove (5a) point It is formed of a sensor (7) and a sensor (8) for igniting the ignition unit (7), the planetary gear assembly (2) is the outer fixed gear 20, the inner planetary gear (30) and the spool (3) ) And a sun gear 40 interlocked with each other, and formed with a carrier 60 for fixing the planetary gear 50 therein, and the carrier 60 is configured to be fixed to the pinion 4 by means of shaft joints. Characterized in the pretensioner of the seat belt assembly.
