HNR Survey

[Mad Mike]

There's a short surveys on HNRs here - http://www.surveymonkey.com/s.aspx?sm=LmA0QmnXEuZTkIY47yT2sg_3d_3d - that everyone is invited to complete. The more responses the better.

Dumb question, but I have not been able to find an answer to it since I say this on the Issac web site. What is RSI and does ANY motor sports sanctioning body recognize their certifications?

I suspect you'll find little regarding RSI outside the Isaac pages ...

Seems a bit odd to me - spend a bunch of resources attempting to create a certification entity because an existing one didn't approve your design rather than just modify the design to meet the requirements. There's no telling why some are prone to tilting at windmills but if that's their gig, so be it.

That's not odd at all.

I read the SAE paper by the developers of the ISAAC back when the paper was first written and think that their ideas make a lot of sense (using a motion damping device like a dashpot to dampen the movement of one's head).

Does it seem odd to you to court existing certification entities to create a standard that excludes your competition?

Don't get me wrong. I think the HANS is a great invention. I think some of the politics of motorsport "safety" and it's lucrative market is a farce.

I think they are stuck. The thing that makes them "novel" and worthy of a patent is the dashpot design...the very thing that makes them ineligible for 38.1.

Contrary to many, I'm not convinced the ISAAC is snake oil. In fact, as a lover of mechanical things, I find it a more fun, techy solution than a brace with another web of polyester belt on it. If it can show a discernable advantage by the damping motion (or if an independent agency could put the debate to rest), then I still think it might be the ill-fated Mac to Hans's PC.

Not to mention stifle innovation.

The link to that survey was shared on numerous racing forums (rally, road, desert, etc) and the results can be found here - http://www.trackpedia.com/forums/showthread.php?t=4958

Look here - http://www.racesafetydata.info/ - for all the info Jim Lill has put together on this subject.

Thanks for the links, Mike; good data.

As for the Issacs device, well if it works, it works. The 30 degree tes results are fine, and from looking at the design, I don't see any clear reason to imagine that the o degrre tests woudl turn out badly. But Greg Baker could hlep himself to produce those test results and put some of the ridiculous speclations to bed.

The thing that I understood to originally be in the way of SFI acceptance was the single point of release thing. I am not as concerned myself about that, because I think one is much more likely to have a long exit delay in exiting a car due to a twisted door or some such thing rather than the couple of seconds needed to do a couple more releases (on something you have released dozens or hundreds of times prior to an accident). The whole deal seems to have devolved into a confrontational thing between Gregg Baker and the SFI, mixed with some politics of competition, that IMO should not be there. So I don't see this getting resolved anytime soon. Can't blame Baker for firing up the RSI.

In my roll at RWV, the HANS release was the least of my problems. I released them right away and tried to take my helmet off because it was "stuck" preventing me from exiting the upside down car (I was crawling out too far front, if you know what I mean, and I think it might have been "stuck" between the steering wheel and the cage. If I had slid towards the back of the car It would have been/was no problem to get out with the helmet on). But back to my original point. I could not get the strap open holding the helmet on my head. But the HANS releases were no problem to get off.

I could not get the strap open holding the helmet on my head.

Many of the better helmets have a little pull tab attached to the buckles on chin strap that, when pulled, helps to relieve the tension of the chin strap on the buckles, and releases the chin strap that first little bit ... after that further loosening and removing the chin strap becomes much easier ... of course easier said than done, and when calmly done when in the safety of one's living room, compared to being in a car hanging upside down in the middle of the road when the next car is only sixty seconds behind. But if your helmet doesn't have a little pull tab on the chin buckles, it would be really easy to sew one on.
