Abstract
A vehicle seat belt retractor comprises a tension-relief mechanism in which a spring-biased hook pivotably mounted on a hook carrier that rotates with the belt reel selectively engages teeth on a stationary stop ring to lock the reel against rotation. The hook is in some states of operation latched by a latch spring so that it cannot engage the stop ring. Latching and unlatching of the hook is controlled by an abutment on an actuator ring that is coupled to the stop ring by a friction clutch. The actuator ring also has a peripheral wall that is engaged by the hook in certain states to prevent the hook from engaging the stop ring. A notch in the peripheral wall allows the hook to pivot out to engage the stop ring in the tension-relief mode.
