Abstract
Abstract A SPRING-LOADED REEL OF A VEHICLE SAFETY BELT INCORPORATES AN INERTIA MEMBER WHICH IS SENSITIVE TO A LATERAL TILT ON LATERAL ACCELERATION OF THE VEHICLE AND ACTIVATES A PAWL AND RATCHET MECHANISM FOR TEMPORARILY LOCKING THE REEL. A PIVOTED BLOCK PERMANENTLY JAMS THE INERTIA MEMBER IN THE LOCKED POSITION WHEN THE VEHICLE TILT EXCEEDS A PREDETERMINED VALUE.
