Hans Device

I guess what I am missing is what happens to the part that rests over your shoulders when you are trying to exit the car . . . Do you slide it up off of your shoulders, or just leave it on when you exit. . . . Sorry for being so dense on this issue.

Yeah Prof, I have been all over that website. I don't see how the additional harness can make it easier to get out of a car with HANS than it is to get out with an ISAAC.
If someone is telling me that it is no problem to get out with either device (provided both have the quick releases), then I can believe it.
Since Colin is telling me it is easier to get out of a car with HANS than it is with an ISAAC, where you don't have the harness to deal with, then I want to understand the basis for this statement. This is one of the reasons why I went with ISAAC over HANS. I didn't want to deal with the harness . . .

We're not being clear, Todd. If you disconnect the straps between the helmet and the HANS then once your belts are released the HANS can slide off the back of neck and be left in the car. I think most people would leave it connected, however, and once the belts are released exit the car with helmet and HANS connected at in place. The helmet is wider in all dimensions than the HANS.
That said, I have never crawled out the window of my car, with or without helmet or HANS. I suppose that might be something to try given that my seat is pretty low and the steering wheel is there. Let's not even think about trying to practice with deflated airbags (mine are still installed--I drive on the street!) hanging around me and after an impact!

Thanks Chris. That is what I wanted to know.
Since it is somewhat difficult to get into, and out of, my car under normal conditions, I was very sensitive to putting myself in a position where I might have anything that could slow me down. Of course, I couldn't really try the HANS out long enough to see if it really would be a problem before I bought the ISAAC, so I have an open mind about the whole issue.
I am a fairly big guy. In a 944 with a full cage, I feel a "bit" claustrophobic as it is. I was worried about the harness. With the ISAAC, I just pull the pins (which you have to do with the HANS anyway), and I don't have to deal with the harness at all . . . That is not to say the ISAAC necessarily is better. I am just explaining my thought process.

Regardless of what you use, I strongly suggest that you repeatedly practice quick exits from your car. You will likely be surprised at what can snag on what. If you experience that a couple of times, your chances of understanding what is happening in a crisis, and handling it, are much better.
As an example, in my practice exits, I have found that the sub srap (formula car style) will sometimes snag in the loop on the lap belt - especially if I am trying to exit before everything is really loose. Knowing that, and having felt it, I have a much better chance of recognizing when it happens in a real emergency and simply reacing down and tugging in the right place, rather than struggling.

I think it is because the HANS does not require the QR's to be used to get free from the car. They are more like a back-up feature. This sort of begs the question as to wht you would need a backup feature...
Did you get my e-mail?

Your HANS is unsafe?
Sunday Driver says it's so
check with Colorchange!
Ahh, Perf & Comp board
so many posts but almost
nothing useful here
8 flips and he's fine?
Bimmer's are strong I suppose
Hand have HANS or not?
I have seen enough
of Rennlist bravado so
now its time to nap

You guys are smart enough to get a Hans in the first place, so it baffles me that you would use it incorrectly.
The only people who should be answering this question in the first place is Hans. Just call them. I doubt they will tell you that you need a new one just to make money off you.

Just joined, but it sure scary to think that Joey could have burned to death if that dripping gas caught on fire. (and he couldnt get out) ive hear and seen of more drivers unable to get out of the car with the hans device on, than i can keep count. sure, its conceptually a great ideal, but it seems to catch on everything as you are exiting the new race cars! I can only imagine how it would feel to not only be caught on the Hans device, but the panic that would then start to try and get free and get out while fire was spreading!
I used the Hutchens device for a while and it seems to be a great answer to the problem. surely better than without one. problem, no chance of SFI approval, for who knows the reason.
as far as joey goes, as dramatic as his accident was, it wasnt like hitting another car or a wall. at that speed. the car was probably 10ft in the air max, so the forward impact was like the car was dropped at 10ft. on its nose. the g forces for the flipping were significant, but more dangerous for being shaken in all directions for some time as the car started to release its kinetic energy. He survived due to the length of time it took for the car and him to stop. remember, its not the speed that kills , its the sudden stop! a young strong guy like joey probably was fine with or without the Hans. Ive seen a few BMWs go into walls creating a lot more front end damage, and lots of red marks where the belts dig in on the chest and shoulders from a single impact.
I think the key thing for hans to do is to have more of a quick release like the hutchens device has . (two pull cords and you are not connected at all!) . Most racers biggest fear is not impact, it is burning!

funny! I use the Hutchens in club racing now, and before last year, it was legal in pro racing as well. all im saying is that in a serious accident, if you got to get out of a bent up car, or even a straight one, there are lots of stuff to catch and keep you in the car to fry!. ever time yourself on how long it takes to get out of the car? all it take is one issue like we are talking about, and you are dead!
hutchens is a great idea, maybe there is a blend of hutchens and HANS that will be safer due to this issue. you maybe got out of your car, but guys with more complete cages and lots more stuf in the way, get hung up all the time getting out!
