I understand where those of you who are pro-Hans are coming from. But, in
the last couple of weeks I have had a conversation with someone who was at a
head restraint test session. He said that while the Hans device functioned
well in straight-on crashes, at side-angle crashes it did not. That was
because the shoulder strap on the impact side was dislodged. Now, that
would still leave the opposing side in position, and this is the one that
would hold back the head in an impact. But, it makes me wonder what would
happen on the rebound.
Then last week, I helped a friend buckle into his harness pre-race. The
"channels" for the shoulder harnesses on the Hans device seem too shallow to
me. And, that would account for the shoulder harness falling off on impact
as in the test noted above.
I was talking to someone at Simpson yesterday & they told me they have a
head restraint device. It's on their web site
(http://www.simpsonraceproducts.com/products/product_detail.aspx?cat_id=179
<http://www.simpsonraceproducts.com/products/product_detail.aspx?cat_id=179&;
prod_id=1773> &prod_id=1773) and only $450. Any of you know anything about
it?
What about the White restraint
http://www.speedwaysafetyequipment.com/whiteheadrestraint.html at $375?
What about the Hutchens II at $750? Their phone doesn't answer. But the
web site is: http://www.hutchensdevice.com/home/hutch2.html
What about LFT Technology's R3 - see:

for an interesting graph. Any idea of the price on this?
If I'm buying brain & neck insurance, I'm not going to cut corners. But, it
sounds like I'm not the only one who needs more info about these devices.
Any & all feedback will be appreciated.
