Abstract
A retractor and method for preventing premature movement of a lock pawl or bar toward locking engagement with a ratchet driven by the drum of the retractor structure and achieved by a torsion spring connected to and driven by the drum. The drum movement in both a retracting and protracting direction applies opposite biases to a pawl blocking element and the preselection of each bias zone being achieved on assembly of the spring to the retractor drum at a selected point in retraction and protraction.
