ABSTRACT:
A seat belt retractor has a rotatable spindle from which a seat belt is unwound. During rotation of the spindle, a cam member is rotated by a gear assembly at a speed which is less than the speed of rotation of the spindle. After a predetermined amount of the seat belt has been unwound from the spindle, the cam member moves an actuator member from an unactuated position to an actuated position to effect movement of a locking pawl into engagement with a ratchet wheel. The locking pawl engages the ratchet wheel to block rotation of the spindle in a belt unwinding direction. A detent engages the actuator member to releasably hold the actuator member in its unactuated and actuated positions. The actuator member has a cam follower section which is received in a cam track on the cam member. The cam track has cam surfaces which engage the cam follower section of the actuator member to move the actuator member between its unactuated and actuated positions. Movement of the actuator member to its actuated position moves a spring member to effect movement of the locking pawl into engagement with the ratchet wheel.
