Abstract

A seat belt retractor has an adjusting clip attached on the lock bar. The adjusting clip is generally U-shaped with spaced apart legs defining a slot by which the clip is engaged over the lock bar. One leg of the adjusting clip is disposed on the side of the lock bar adjacent the reel and has an integral depressed portion which is engaged within a mating aperture of the lock bar to retain the adjusting clip on the lock bar. The other leg of the adjusting clip is disposed on the side of the lock bar adjacent the pendulum and has an integral protuberance extending therefrom into engagement with the control head of the pendulum. The dimensional projection of the protuberance controls the gap between the ratchet teeth of a belt reel and the unlocked position of the lock bar. A plurality of adjusting clips are provided having the protuberances thereof projecting at various dimensions. After assembly of a selected adjusting clip on the lock bar, the at-rest position of the lock bar is gauged to determine if the gap is within a specified tolerance. The gap may be adjusted if necessary by replacing the adjusting clip with another having a protuberance of greater or lesser projection.
