Abstract
The safety belt retractor of this invention has a belt-sensitive mechanism and a vehicle-sensitive mechanism, both mounted on an actuating mechanism. The actuating mechanism includes a mounting plate slidably mounted on the reel shaft for limited rotation and a flywheel having ratchet teeth. The vehicle-sensitive mechanism includes a pendulum assembly and an actuating pawl. When the pendulum assembly oscillates, it lifts the actuating pawl which engages the ratchet flywheel, causing the mounting plate to rotate and actuate a locking pawl. The belt-sensitive mechanism includes a pinion gear and a spur gear which is driven by the reel shaft. When withdrawal of the safety belt exceeds a predetermined level of acceleration, the flywheel lags in rotation and causes the pinion gear to move along an arc of the spur gear, causing the mounting plate to rotate and actuate the locking pawl. Rotation of the ratchet flywheel may be synchronized with rotation of a ratchet locking wheel to facilitate immediate engagement of the locking pawl with the ratchet locking wheel.
