Abstract
An improved dual tension retractor mechanism for emergency locking safety belt retractors which allows application of main spring rewind bias without the necessity of an initial low tension belt rewinding. Application of the main spring rewind bias for belt retraction from low tension use mode is controlled independently of retractor reel winding or unwinding movements. The improvement includes a ratchet ring which is selectively rotatable relative said housing to allow reapplication of main spring rewind bias to the belt when the belt reel is in the low tension mode. Retractive rotation of the ratchet ring applies power rewind bias to the belt reel even though a bias blocking pawl remains engaged with the ratchet ring.
