List,



This isn't intended to prolong or enliven the aforementioned subject......however,

With all the talent present on this and related Lists surely there is somebody who knows something about automobiles and the designed-in "crumple zones".   Possibly some of that expertise might apply here.

Obviously there are two extremes; nearly nothing and too much.  We're all probably seeking something in between.  

I would speculate that none of us wishes to BE the crumple zone.....we'd rather walk away like Jon even if it did include some scratches.

A previous post mentioned the wise addition of a shoulder strap as an augmentation to the lap strap to preclude head-banging.

I'm going to stick my neck out on this one.....maybe if the belt attach brackets hold (don't jerk loose from whence they're fastened) then the remainder of the assembly (the airplane) will bend and distort while the aircraft decelerates.

This accordion feature might be one of the cat's nine lives.

If memory serves, a certain designer of ag aircraft intended that big parts (engine, hopper, wings, tail, etc) begin shedding themselves while the box containing the pilot stayed intact when the entire assembly unintentionally came into contact with the ground. 

Seems like a logical approach.

Okay, slide rule jockeys, jump in any time.



Maybe its the heat,



Regards,



Zed

We don't want to put this subject to bed yet do0 we?  

 I may install two additional brackets at the rear0 of the baggage compartment( 701), then link them to the forward brackets with0 belt material with 2"+/- of slack. One would have to pull out 20 brackets, sequentially. What do you think?

I think your best bet would be to eliminate the slack.  An airplane crash doesn't stop until all the aluminum is resting on the ground.  What I mean is the initial force that may pull the first bracket out will most likely still be present for some time during impact as the plane crumples (damn, now that jut doesn't sound like much fun!).  eliminate the slack and you double your resistance to breaking a single bracket.  The airplane is going to provide some amount of deceleration protection as it crumples so the brackets need only hold the pilot to the airframe as it does it's job.

    

    Let's call this my 1/2 penny's worth...
