ABSTRACT:
An improved safety belt retractor comprising a ratchet means, a locking means which is engageable with the ratchet means, and an actuating means which is actuable in response to a predetermined acceleration for engaging the locking means with the ratchet means, wherein the improvement comprises a flexible means for spacing the locking means from the ratchet means and for allowing the locking means to engage the ratchet means upon actuation of the actuating means. The spacing means eliminates the rattling noise caused by the metal-to-metal contact between the locking means and the ratchet means, but the spacing means, being flexible, permits the locking means to engage the ratchet means upon actuation of the actuating means.
