Abstract
An emergency locking safety belt retractor having a safety belt storage spool, a locking ratchet turnable with the spool, a locking pawl for preventing spool rotation when engaged with the locking ratchet, a programming ratchet turnable with the spool and a locking pawl actuating means operable in response to a change in vehicle inertia sensed by a vehicle inertial sensor has an improvement in such locking pawl actuating means including the provision of a flexible member having a programming ratchet engageable tooth provided thereon, a connection between such member and the locking pawl for moving the locking pawl into a lockup with the spool mounted ratchet when the member is moved in response to a change in vehicle inertia sensed by the associated sensor and a closed loop cam way is associated with a follower on the member which causes the flexible member to store energy while being moved by the programming ratchet to cause the locking pawl lockup which is released after such lockup and then moved in a manner to cause the flexible member to return to a position of rest in a reset mode without being dependent upon a spool retractive movement or a release of the locking pawl to accomplish the reset movement.
