Abstract: Seat belt web retractors having web locking mechanisms are described herein. In some embodiments, a seat belt web retractor includes an inertial locking mechanism operably coupled to a spool about which a seat belt web is wound. The web retractor further includes a web locking mechanism operably coupled to the inertial locking mechanism. The web locking mechanism can include a driving member that is actuated by engagement of the inertial locking mechanism with the web spool in response to rapid extraction of the web from the retractor. Actuation of the driving member drives first and second clamping portions toward each other, thereby clamping the web in between the clamping members and restraining the web from further movement out of the retractor.
