ABSTRACT:
Disclosed is the anti-rattle restraint of an otherwise freely pivotable, unevenly counter balanced seat belt looking pawl subject to rattle with vehicle vibration. A light bias urging the pawl out of contact with the ratchets on the belt spool is maintained by an arm mounted on the spool shaft with a frictional fit sufficient to maintain the bias on the pawl and to effect instant removal of the arm upon withdrawal of the belt from the retractor, but inadequate to retard rotation of the shaft after the arm has moved through the limited arc of travel permitted to it.
