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.

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 built one about 15 years ago for PCA club racing

I decided to punch a hole in the firewall and build a bracket that slid through the firewall to the seat. It was adjustable with a pin in the engine bay because we had 2 drivers and needed an adjustable seat.

my only thoughts about safety are:
if a wreck bad enough to deform the roll bar occurs... the seat could move forward or backwards with the bar and cause the belts to get tight or loose...

I know its not likely the roll bar would deflect, but you never know in a roll over situation.

by tying the seat brace to the firewall it was tied into the same place as the belt mounts... I figured if the firewall moved at least the seat would deflect with the belts instead of independant...
