Legal seats for stock eliminator

[HandOverFist]

Can't say I really understand the safety aspect of the aftermarket seats over OEM. My stock seat back rests against the roll bar and I have a head support/cushion welded to the upper hoop. In the event of an impact I can see the back of the seat being able to fold if my body is not resting against it, but the harness is attached to the roll bar and floor pan which precludes me from forming any measurable distance from the seat surfaces. I can see some improvement with modern seating in the form of lateral support in certain situations, but that's about it. Now if I had an impact from the rear with the stock seating I could envision greater problems.

Mark, I'm sure a lot of cars that don 't have to have a roll bar have them anyway. My car my wind up in N/SA but I plan on a cage anyway. My question is if a bar/cage is not required, but is present, is it still required to brace the back of the seat to the roll bar? If so, only aftermarket seats or factory seats too?

I'm more curious regarding my bracket car actually; it doesn't require a cage or bar but it has one anyway.
