ABSTRACT:
Disclosed is a seat belt retractor in which first and second locking members 14, 16 are engaged with a ratchet wheel 13 independently of each other via a link member 18 when sudden acceleration is sensed. Owing to this engagement between the first and second locking members 14, 16 and the ratchet wheel 13, first emergency locking means 15 locks a reel shaft 11 against rotation while second emergency locking means 17 locks a seat belt 12. Accordingly, the first emergency locking means 15 and second emergency locking means 17 operate independently of each other, and it is possible to readily adjust the timing at which the reel shaft is locked against rotation and the timing at which the seat belt is locked by being clamped.
