Guess my new -20 suit with sewn in D-rings is not legal now. Rad
from the way i understand the rule change is,only the adjusters are the change,not how it attaches to the arm or belts.If I am wrong I would love to have this confirmed!

I think we need way more clarification of what is actually required for hardware and where. My Pyrotect restraints have a large welded D- ring on the end of the strap that the seat belt latch goes through,  a pair of small D rings to tighten the arm bands, and a one piece "ADJUSTER" on the restraint strap between the arm and the belt. I have no idea if this is legal for SCTA.

Ron
4. Section 3.D.3 Arm/Leg Restraints: Page: 42 Add what is in bold after the first sentence in the first paragraph; SFI specification 3.3 arm restrains with a manufacture date of 2006 or later are required in all vehicles. IN ADDITION: ALL ARM RESTRAINT HARWARE MUST BE OF A SINGLE PIECE MANUFACTURE. I.E. NO TWO PIECE OR WELDED D RING STYLE ADJUSTERS. ADJUSTABLE TETHERS SHOULD USE A 3-BAR SYSTEM SIMILAR TO THAT USED IN LAP BELT ADJUSTERS. NON-SOWN IN RESTRAINTS SHALL HAVE A TIGHT FIT AROUND THE NARROWEST PART OF THE ARM. ALL ARM RESTRAINTS MUST BE DEMONSTRATED TO BE EFFECTIVE.
To me, this means any welded ring is likely to be non allowed even if it is not part of the adjuster. This needs clarification from/by the inspectors. Photos of the restraints posted earlier show a proper 3 bar adjuster but what looks like a D ring or similar as part of the attachment with velcro that goes around the arm. Even though the above quote says "adjusters" it may be questioned.

And 3 bar system SIMILAR to that used in lap belt.Mine now have a 3 bar system but is it similar enough?

I bought these same ones last year.  I'm curious as they are 3 bar style, but also two pieces.

The rule, quoted above, clearly says "single piece manufacture". Two piece 3 bar are likely to be problematic.   cry JMO

Just talked to DJ, they inspected our arm restraints and HNR after the crash, they said ours will come back in compliance with the new rules. 
The way I see the new rule is no more D-ring adjusters...

Pegasus Racing actually has the specified adjustment plate available for 1.75 to 2 inch straps. Duke and I are going to look at his Simpson arm restraints and see if they could be converted to this type of adjuster, would that void any type of warrentee or the SCTA new rule? We also considered having some water jet cut from some stainless plate to the exact strap width. Going with the DJ stuff is probably the best way.

I know that the SCTA does not make these type of changes without a good reason, have they seen failures of arm restraints with the welded "D" ring configuration?

Rex- depending on your restraint strap width, there are a lot of adjusters out there that probably would work, including of course the Pegasus ones. My straps are 1" wide and a bit less than 1/8" thick, doubled about .20". I just got a couple of these from West Marine- other sources available for sure. Stainless, thicker than the hardware that attaches the strap to my seat belt- made by Pensafe that makes climbing gear and other safety stuff- and the fit is perfect for my straps. West marine is not the cheapest place in town but $3.29 retail I suspect is a lot less than you can get them water jet cut for. wink

Is the SFI tag still good for a modification?

Now I am sure that was a very tongue in cheek question.  evil cheers
Am sorta thinking that you send your restraints to mfg and they take out the D rings, install a 3 bar and send them back, the same applies. Not tested by SFI ( I assume they test these things, not just say Acme Safety made them so they pass, here is your tag.) Another can of worms.

So I have the double d-ring arm restraints sewn into my suit. If I am correct, I cannot cut these off it because it will be a modification of the suit rendering the SFI null. SO I will need to buy slip on arm restraints and just leave the sew ins dangling around as an extra hazard.

 Last year I cut off my old sewn in out dated restraints, never had a problem. Inspectors only wanted to see the tag on my suit and the slip on restraints. Of course your results may be different?

Hey Brian, those brand new DJ restraints you just bought aren't legal!  That's not a true 3 bar adjuster.

What do the built in limb restraint attachments have to do with the SFI fire rating?  NOTHING.  Cut them off.  Unless the attachment points were down at your wrist, they were worthless any ways.
