Abstract
A seat belt retractor has a frame, a spool rotatably mounted to the frame, a spool locking device for preventing rotation of the spool. An actuator actuates the spool locking device and has a support carrying an inertia mass and a pawl. The inertia mass is designed to move from an initial position to an actuating position to bring the pawl into engagement with a ratchet on the spool. Engagement of the pawl with the ratchet actuates the spool locking device. The support is arranged to pivot so as to adjust the distance between the pawl and the ratchet. In that way the position of the pawl can be adjusted to provide an optimum gap between the pawl tip and the ratchet on the spool.
