Inertia reel lock?
I thought he whole idea of inertia reels was that they automatically lock on either the belt being pulled out quickly, or upon increased G forces acting upon them. This capability can very easily be observed or demonstrated even under normal operating conditions (unlike air bags where the G switch settings are so high that only a real accident should activate it).
None of the inertia reel seat belts I have ever seen in civilian aircraft or cars had a manual override lock.
