<p>An inertia-responsive actuating device for emergency locking vehicle seat belt retractors comprises a ball which normally nests stably in an annular seat but which rolls out of the seat and pushes down on a detecting portion of a pivotable lever. A hole in the lever detecting portion defines a circular detecting edge which matches and engages a lower portion of the ball located above, but proximate to, the ball seat and substantially below the center of gravity of the ball.</p> |
