At what distance? At the mounting point 10 inches behind your head? That's not what they recommend. They wnat it 3 inches apart 6-8 inches behind your head and not spread by the harness guides in your seat.

I was trying to be nice!

hey , you are right, its dated 2005.

Now, its still fine. sure a new one is better, but if someone has a old hans 650 from 2005, its stil legal. ive seen this on the shoulders of cup drivers all the time. it either works or it doesnt. its not a wear device. hmmm, guess it was designed bad if have to pitch it because it was designed bad.

mark kibort

yeah, my head is 1 " from the seat back, and the distance is the 6 " behind my head.they come out of the seat holes at 3" still too. its a straight shot.

Ill stop typing and start downloading pics.

thanks

Dated 2005?

Does the SFI certification label have a punch hole next to "date of manufacture" or "recertification?

Mine is from April 2005 and has the raised lips. I have a hard time believing yours was also made in 2005 yet does NOT have the raised lips. I suspect yours was recertified in 2005 but is much much older. And again, it is a "wear device" if it was involved in an accident and not recertified since 2005...or was partly ruun over by a race car trailer...or accidentally stepped on...etc.

But hey, it's YOUR head, not mine. I would never, ever buy a used HANS, especially one that is "only 5 years old" that turns out be closer to 10.....

mark kibort

yep, it was a bad call and its funny, the guy (who i know, but not realy friends with) thinks he had a bag of gold! i didnt even check the dates. I know his story, know he has been out of racing for a while, but didnt know how time has flown. I dont think it was recert, it looked like all the stickers were original

loading up the pics now.

Here are the belts as they go through the seat

This is what I don't understand. When I'm strapped in without Hans, I can barely move around in the seat. With the Hans there is no movement at all of my torso. I feel as a part of the car. It makes so much difference in my driving, because I don't have to use the wheel to help keep me solid in the seat.

From your description it seems like you have a lot of movement if you can lean forward. Because in a wreck any friction will be worthless to keep you in position.

Mark,

What is the width of your HANS at the base of your neck? That partly determines the belt width formula. By your picture your hans is about 9" from your harness bar. With a 160mm wide hans that would put your belts about 3/4" apart so your back brace would need to be repositioned. If you have the smaller 140mm hans the belts should be touching.

Hans has FIA sticker so you don't have to comply with 38.1 recerts with SCCA. But it is a good idea to replace teathers with the sliding teather and larger washers for $75 bucks. This is a diy thing unless you want to send the hans back for a recert too. If you got the FIA sticker you are good unless you suspect being run over by the trailer etc...

Also, you appear to have enough belt length. Increase the shoulder length so that the adjuster is between the tip of the hans tail and a point 2.75" from the hans tails. You do not want the adjuster as pictured. Your harness bar looks very close to the 20* limit. Measure it.

Your seat looks short for you and the head rest area does not appear to support you in a rear impact. I guess your helmet will be stopped by the cage but I would prefer layback built into the seat with proper support of the head as opposed to what looks like a seat tilted to fit the cockpit and compromising your safety support. Your safety in the car starts at having a seat that fits you.

I'm not a pro...so verify!

mark kibort

yes, the seat needs to go, and thanks for the info. ill move the belt adjusters to be further down toward the tails, as im changing out the belts too, as they are expired this year anyway.

what is the 20" llimt??

thanks for the input!

Mark

mark kibort

again, hard to explain, but remeber, i was in a high speed frontal crash and the belts worked fantastic, but was a very scary event. the belts held perfect. with the hans on, there is some movement, even strapped in very tightly. there is no movement with the belts and no hans. this is my concern.

He is talking about the 20 degree limit for the angle of the shoulder belts going from the Hans Device over you shoulder down to the bar where the shoulder belts attach.

the seat has to much rake, the hans should be touching the head rest. You need a seat with more shoulder support also

Looking at the seat, it looks like its very reclines, the belts are angling downwards to the bar. So, I can see that when tightening it creates a "pinch" on the driver without actually securing him in place, because once you recline further or slide down in your seat the HANS will get loose again. One thing I'd like to point out is that it appears that the belts are "hovering" in the seat slots. This will compound the problem.

Then, as already mentioned, no lips on the HANS. So it will tension-mount but thats it.

Finally, those look like wide-belts, not compatible with HANS, or at least they look like a ham-fisted fit. Do you get chafing on your neck? You shouldn't.

Put it all together and the whole setup looks wrong. The driver position makes me think you may need the Open-wheel (F1) HANS. But then the bar height, seat, everything, just doesn't look right. Honestly I would take the car to a race shop and get a hands-on expert to give suggestions.

Veloce Raptor

Agree with all comments: entire set up is wrong. Seat too reclined & not the best choice of seats. Adjusters way too high. Etc. And I guarantee that HANS is a recert--no way it was manufactured in 2005 w/o a lip.

DAMMIT MARK. I've let this go for 2 days now.

For all of this, after all this time and after all of the threads in which you just tear loose...I respect you and your comments. Regardless of the way that you present your opinions, they are often grounded in solid fact, and if nothing else, well RESEARCHED.

Why the fark would you not do the same research when you jump into the safety game! Damn, man, even a rank newbie such as I can dive into the interweb and become as well informed about these devices as almost every soul here.

Giterdone man...damn.

Rant over.
