Abstract
A reel-type retractor for a vehicle safety belt designed for halting rotation of the reel in response to an inertial device, and having the added feature that the belt can be withdrawn from the retractor for buckling up without interference from the locking pawl. A clutch, rotating with the reel, is shaped to restrain a biased webbing follower, and to block the pawl from engaging a ratchet wheel serving as a flange for the reel, thus permitting any rate of withdrawal of the belt without locking the reel. When the user buckles up and the safety belt is retracted slightly as occurs in buckling, the clutch rotates to release the webbing follower which then moves toward the diminished roll of webbing and prevents the clutch from regaining its blocking position, thus allowing the pawl to engage the ratchet wheel in response to the inertial device.
