Chapter 8 is about making the rollover structure and seat belt hard points.
The lower seat belt attachment points were installed in Chapter 7 prior to glassing the outside fuselage. This was to prevent from having to drill through the fiberglass and then have to patch it up later. See "seat belt hard points".
The upper seat belt attachment points are attached to the rollover structure (for the pilot) and to the center section spar (for the passenger).
::I have yet to purchase or pick out a seat belt type - I will update this section when I come around to it::
The original plans has you build a rollover structure out of composite material; however, the following was posted on Page 7 of CP#65:
"The FAA has requested that RAF make it clear to all VariEze and Long-EZ builders that the triangular shaped foam and fiberglass headrest on top of the front seat bulkhead is just that, a headrest. It is not a roll over structure. It will not support the loads that would be imposed on it in the event of an accident in which the aircraft might flip upside down. The construction of the headrest triangle is such that it is a lightweight, stiff "box" that makes an excellent storage area for maps, logbooks, etc. and, with a cushion attached to the forward face, it makes for a comfortable place to rest the back of your head when flying. The light weight foam and glass structure can not possibly support any turnover crash loads. As the builder/pilot of a VariEze or Long-EZ, you should be aware of this important information."
Oh.... ok... well thank you for that.
There is a floating document outlining the steps on how to build a legit rollover structure out of composite materials that can withstand the loads in the event of a rollover accident. In my opinion, this option is very labor intensive, very costly and looks pretty terrible (not to mention it might also obstruct the view of the passenger in the back).
On that note... most builders take matters into their own hands and build personalized rollover structures. It's not that hard to do out of tubular 4130 steel. My plan from the get-go was to purchase the materials and have a professional welder simply weld everything together.
Here is what we are trying to build - basically, its two 'L' angles attached by two tubular supports. Two other tubes make up the main triangular structure which attach to the forward support. Lastly, two braces run from the triangular structure to the aft support. This entire structure then gets bolted onto the top longerons.
