[DeTomaso] Evidence of helmet chin-strap failure at Pony Expressaccident - Helmet chin-strap design

[Mad Dog Antenucci]

We  should get some actual feedback from Hans engineers via Mike Borders in a few weeks.
   
  As I said earlier there are allot of different variations and opinions  of where or how the chin strap failed...I think it is as you, Chuck and Michael previously noted...just a reminder to make sure you and your team double check your chin strap along with your harness to make sure it is in fact secured properly.

  Did the strap actual break or was it the mount points on the helmet or D

The straps on my Bell helmet are Kevlar. I am guessing that the other major
brands use Kevlar or something of equal strength. I cannot believe that the
strap itself would tear in two.

I hate those double D rings. It always seems to take me a while get it
threaded through -- usually while someone is waiting behind me to get on the
track. I bought one of those quick snap clips a while ago, but I am
wondering now if that is a good idea to actually install it.

There now appears to be evidence that the helmet chin-strap 'broke' on the
helmet of the driver sometime during the ensuing roll overs of their cup car
at the Pony.

The navigators helmet which was completely off his head at the accident
scene is another story. He couldn't remember if he pulled his helmet off
'after' the accident but the helmet and Hans strap was not damaged or
broken. 

There was evidence of hard surface wear scrub on both their helmets and
the Hans Devices that both were wearing. Both helmets and Hans devices are
going to Hans for a thorough investigation.

Lots of questions on helmet strap design. I don't like the way the helmet
chin straps are connected with the double o-rings you have to thread....its
easy not to get it right and its always a good idea to have buddies or start
line personnel double check when they are tugging on your harness.....but
the bigger question in my mind is there a better helmet chin strap design
out there? 

Anyone looked at this subject before?
