Nutloose, I don't disagree with anything you say, but I'm expecting a definitive yes or no from a FJ pilot. This is after all, a deadly piece of kit.
But seeing as you took the trouble:-
If you were on a backseat trip and your strap caused the seat pan handle to come out of it's housing
Would you push it back, knowing without doubt that the mechanism was reset?
Would you tell anyone?
