In re: inertia (or inertial, but not interial) reels
The term derives from Newton's concept of inertia, and here refers to the
means by which the mechanism "locks" when subjected to rapid deceleration.
Many aircraft and all late model automotive three point seatbelts employ
this technique to allow freedom of movement unless and until the vehicle
decelerates suddenly.
For a brief description of the product, and how not to install the things go
FAA's guidance on the subject go to

Ira,
"He is no fan of interial reels either."
Can I ask what 'interial' is? Is that the site of its
base(inside) or a reference to the reel function?
"Also, he thought 3 inches of tempurfoam is not adequate for safely passing
the 19g vertical acceleration test."
I haven't been around to the back to check contours, but I
suspect my posterior would be content with the quality of 1 to 1-1/2 inches
of that expensive cushioning - on top of stiffer underlayers of course. I
wonder what the good perfesser would think of Graham Singleton's
consideration that a fair depth of foam 'worms' a la beanbag principle had
saved his 'bacon' on pranging?
Nervously,
Ferg A064
