Abstract
An inertial locking device for blocking the rotation of a shaft. The device comprises a pivoting ratchet which is brought into contact with a gear means to prevent further rotation of the shaft by virtue of the displacement of an inertial mass within the device. The device may be used in conjunction with a seat belt retractor so as to prevent further extraction of the belt in the event the retractor is subjected to a destabilizing force.
