Hi Fergus!
An inertial reel locks on rapid deployment.
I don't have answers for the seat pan (yet).
A Mechanical Engineering consult would be
very useful here. I will be looking into it, but the
outline of the vision is perhaps an inch of "soft"
honycomb crush zone with a thin aluminum plate
to prevent crushing by stepping on the seat.

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?
