A vehicle seat belt retractor comprises an emergency locking mechanism that responds to either rapid acceleration of the vehicle or rapid acceleration of the belt reel and a belt clamp that is actuated by a small rotation of the belt reel via a link that engages a ratchet wheel affixed to the belt reel. The link is moved into engagement with the ratchet wheel by camming action by a reel-locking pawl, which, in turn, is moved in response to activation of the emergency locking mechanism.
