  • Pretensioner structure for a safety belt of an automobile
    Patent number: 6732968
    Abstract: Disclosed is a seat belt pretensioner for a vehicle wherein a spool is mounted in such a way that it cannot be further released at the onset of a car accident but can push itself downwardly in a fixed state along the length-wise direction of a retractor and thus can effectively rewind a seat belt with ease. To serve this purpose the seat belt pretensioner of the present invention comprises a retractor cover wherein sliding guides are mounted both on right and left sides, a spool mounted in such a manner that a seat belt is wound up with an elastic support and is able to slide along the sliding guide, and a piston structure, being mounted on the upper part of said cover, pushes said spool downwardly by the explosion force of explosives.
