Abstract
An inertia retractor may be provided with an automatic locking mode by the addition of an assembly mounted as an attachment to sidewall of the inertia retractor. The assembly allows the retractor to be used as an inertia retractor until the belt is pulled to a predetermined extent whereupon a belt coil sensor senses this predetermined belt extraction and operates an actuator to shift a pawl into locking engagement with the ratchet wheels and thereby into the automatic locking mode. When the belt rewinds, the belt coil sensor deactivates the ALR mechanism by latching the pawl actuator thereby allowing an inertia member to again operate the pawl to the locking position upon a deceleration of sufficient magnitude.
