Mandated head and neck restraint
« on: October 22, 2010, 11:48:25 AM »
Take a look at this video and quote.

To quote Danny Thompsen,
"I doubt I would have survived the crash without injury if I had not used the Hans device"

Select the 4% play and see where the head ends up.

JL222, do you really want your son or yourself to go thru this at the 280+ speeds your car is capable of?

Glad this is posted for all to see. On the slo-mo Video I think his face actually hits the steering wheel. Alot of belt stretch but the hans worked perfectly.

That tells it all, being restrained and still having that much movement. Belts do stretch. I remember the first time Bob Higbee pulled my shoulder harness down and smiled, said he wanted me to be safe. A lot has changed and it's why new rules are written and / or upgraded. This video should be shown to every racer.

   If you think thats bad how about a video of a bike rider crash.
  Don't know how I survived those years of districk 37 desert hare and hounds :evil:
   Danny had no problem getting out, but he was opening the door before it stopped [ worried about fire maybe]

                   JL222

  Dan don't short us on our speed thats 280 mph in the quarter 294 in the 1st mile and 7000 rpm = 318 and it blew before the end of the 3 mile :-)

John,

Do you think there may be some correlation between the use of the Hans and his ability to get out of the car?

I tried not to short the capability of your car, I did write 280+ (plus).

  The correlation is a Hans and getting out of my car in case of fire [ going on 20lb diet if rule passes] :-D
  I haven't seen Danny's car but it doesn't seem to have an x brace like in our Camaro
 My firesuit is rubbing on roll bar when I get out due to lack of room between X brace and roll bar + we have a funny car cage which gives us less room.

  Did all the streamliner drivers at Cook's meet have Hans type devices?
  Han's devices were invented to prevent spinal seperation from sudden stop. Danny's crash lasted for a few seconds
  I'll go back to video and count. Wow, about 14 sec looks like spinning and flying for 4 0r 5 sec.

  I'm not compleatly against Hans devices but in some cars there are problems and the SCTA should recognize that.
  I also think that the manufactures are ripping us off, for instance $519 for the roll bar padding vs $363 for a 4 gal dry sump tank.

That video will make you re-check your safety stuff.  Here is the sled crash test from Schroth Racing.

And one on belt adjusters and cam locks

And the best guide on mounting I have found

Did you notice the impact opened and closed his face shield.
Does the belt stretch help cushion the impact?
Would a funny car style cage help?
It gave me shivers.

I think the 14% version give you a more real time feeling. One major concern I now have is the distance required between the top of the helmet and the bottom of the cage when one runs a dragster type cage like all roadsters do. If the belts stretch that much with Danny who is not a heavy person, what happens to the belts when someone weighs 250 pounds. Will broken necks or spinal injurys be more common?

I could not find in the rule book any minimum distance measurement from top of helmet to bottom of roll cage. Or did I miss it? If there is not a distance minimum for over helmet,  this is something we need to address, as the cars are not going any slower, and people keep reminding us about how fast their cars are going.

I love the USA. How much longer will we be a free nation?

Asking questions is one's only way of getting answers.

The rational person lets verified facts form or modify his opinion.  The ideologue ignores verified facts which don't fit his preconceived opinions.

When we have to do it we will.  I just wonder how all of the NASCAR guys survided so many violent crashes over the years?  Yes I know there have been a few unfortunate lives lost.  Does anyone remember the crash where the car rolled about ten or so times and even did a cart wheel.  I'm thinking it was Rusty Wallace but not sure.  I was suprised he survived that one.   :cheers:

Yes, were you there to answer otherwise?
