Abstract
An electrical lock-out mechanism for a door mounted, vehicle-sensitive, seat belt retractor to prevent the retractor from locking up in response to the normal opening of the vehicle's door. The lock-out mechanism has a lock-out finger attached to either the retractor's lock-bar or top to the pawl of a piloted pawl type retractor. A solenoid is positioned adjacent to the free end of the lock-out finger and has a plunger which is displaceable between a retracted and an extended position. An electrical switch responsive to the unlatching of the door's locking mechanism energizes the solenoid to displace the plunger to its extended position to inhibit the displacement of the lock-out finger and the lock-up of the retractor with acceleration below two G's experienced by the retractor's crash sensor when the vehicle's door is normally opened. The lock-out finger is a formed leaf spring permitting the crash sensor to override the lock-out at higher levels of acceleration or decelerations, greater than two G's, indicative of actual vehicle crash conditions.
