Fabrication, Bracket for seat Options

[Randal]

I've got to install a seat bracket before Cascade Lakes, otherwise I might not pass tech inspection.

Been looking at a number of different options.

First of all here are a couple of pictures so you'll see how much space (and angles) I have to work with.

Front view:




From the back at the top:




From the back looking down:




Was thinking about making an L bracket that I can bolt to the seat (the 2.5" section between the holes for the seat belts. I'll use something like a carriage bolt with a rounded head on the drivers side of the seat.

Found a couple of brackets for the roll bar that will work:




Or use a couple of these with the same L bracket




Coleman also makes a parallel one that might be easier to bolt up to the L bracket on the roll bar side.




Good way or is there a better way. All ideas appreciated!

I'm not sure who adopted it first... probably SCCA, but there is a chance it could of been PCA.

I know why PCA requires it though
a gentleman driving a 911 in a club race about 15 years ago
he had a carbon fiber seat
he spun the 911 and wend into a concrete wall backwards at a high rate of speed

the seat broke in half from his body's G-forces going backwards at impact.

when the seat back failed and fell backwards it killed him instantly snapped his spine.

PCA very quickly began requiring seat back braces....
so that the seat could not collapse in that manner
I personally don't believe its necessary with an aluminum type seat (kirkey, ultrashield)

but rules are rules, even if they are blanket rules and don't apply to a particular person's situation.

so that is how the PCA began requiring it for club racing
I honestly don't know at what cronological point the scca began, and whether it was due to the PCA incident or an incident of their own.
