<p>A vehicle seat belt retractor has a belt-sensitive latch mechanism inhibited during belt retraction. A pawl (12) pivoted on the retractor spool (1) by a pivot pin (15) has a pawl pin (17) engaged in a slot in an inertia mass (10), which normally rotates with the spool but which lags when a predetermined belt acceleration is exceeded to pivot the pawl, by acting on the pin (17), to thereby effect locking. The inhibitor mechanism comprises a disc (25) driven by the pin (15) to rotate with the spool in different angular relationships depending on the direction of spool rotation and engaging the pawl pin (17) to prevent latching movement of the pawl when the spool rotates to retreat the belt.</p> |
