Delayed locking retractor

摘要

A pre-emergency delayed locking retractor. A pawl is movably mounted to a retractor frame and is lockingly engagable with spool ratchet teeth with a web wound on the spool. A cam wheel mounted to the retractor frame or a web follower mounted to the pawl are operable to keep the pawl apart from the ratchet teeth until a predetermined amount of web is withdrawn. An inertial device engaged with an end of the pawl forces the pawl away from the ratchet teeth until the retractor frame is moved. The inertial device includes a mass mounted in an unstable fashion to the frame with an upstanding finger contactable by an arm fixedly mounted to an end of the pawl.
