you need to loop that one more time and in most cases the belts would be going through the seat. on a car me and my freinds use for the 24 hours of Lemons (yes like lemonade) I used a stock seat with a headrest and had to weld tabs to the cage to keep the belts from sliding out in order to pass tech.
I second what clintd said, and you need to try and make the loops as tight as you can, don't leave very much slack. What I did, and this has passed NHRA tech, is taken a piece of radiator tubing.............cut it down the center, put one piece between both loops and used radiator clamps to secure the tubing.................then did the same thing on each end................this way the loops can't go anywhere. I tried to look for some pictures but did find any.............hope that helps.
go to the simpson site or impact racing, they have mounting tips in there catalog, should have it in the website too. I cant believe you passed NHRA tech that way, also look at NHRA>com for the rulebook and see what is needed. Duane
Boss302Maverick, Would be interested to see a picture of your attachment. Yes, this has passed NHRA tech and although I am no longer a member of NHRA for other reasons..................how about shooting me a copy of that section. This way of attaching shoulder bars to the roll bar would also be considered Ok with the SCCA, of which I hold a tech license, and in most instances the SCCA has tighter tech than the SCCA. I would certainly be interested in hearing from you. Thanks, John
Pull them as tight as you can and then wrap the extra around the tube next to the belt. Then put a couple of zip ties real tight around the extra. that what I did and have never had a problem.
The post I was reffering to was the first post with no stop to prevent side movement, in the event of on accident, nothing is there to keep the belts from sliding off your shoulders, I wll check the NHRA rulebook to see what the rule says, but here is the simpson instructions that says that stops must be utilized. if you call the manufacturer of your belts, they will be happy to offer suggestions on how to fabricate stops for your setup. I spent 8 years full time and another 10 part time working on the IROC race team and can tell you from alot of experience, that seatbelts, helmets and other safety equipment is looked at like " I have it just cause I have to have it, not because Im gonna need it" and when you need it, you look at it a whole lot different if you get to walk away the first time. Heres the Simpson pdf of seat belt installation , very good stuff about angles and mounting . http://simpsonraceproducts.com/pdf/Seat_Belt_Mounting.pdf Duane
