HANS Question

#1

I noticed tonight that Tony Stewart put on his belts and then put his
HAS on *top* of the belts. Is there now a different way to secure the
HANS to the shoulders?

I haven't taken a great deal of notice if its under or over the belts
before, but can't imagine it makes any difference. The clipon straps from
the helmet to the back of the HANS is the only connection I believe matters.
The shape of it against the body is what stops the head moving forward more
than the spine, regardless if its held agajnst the chest by belts or not.

What good is a HANS device that isn't held down by something?

You can't just sit the thing on your body / shoulders and expect it to
hold your head from snapping forward along *with* the device.

Off cource the same forces that throw the head and body forward will also
act on the HANS itself. But the arms coming down the chest working against
the part around the back of the neck is what stops the head moving forward
faster than the spine, whether it is under the belts or not.

I watched your vid and did a bit of googling and the reason it is so
important to have the HANS device under the belts is to prevent sideways
movement of the head during a crash

It doesnt need to be "held down" to prevent a basilar skull fracture in a
front on impact. (which is the primary reason stated for using them)

Don't you wish you could get that sort of real, meaningful
information from the likes of Tim Brewer in the NASCAR
telecasts?

EuroSport is blowing ESPN and FOX away in quality.

Even with the belts underneath it (which is an incorrect usage), the
only way your head and the device could snap forward is if your
shoulders went forward as well. With the harness pinning your shoulders
to the seat, you still shouldn't have an issue with the head moving
forward as long as the HANS is sitting on the shoulders.

Head inside helmet attached to HANS. HANS *sitting* on shoulders. Head
/ helmet moves forward. HANS that isn't secured with shoulder belts is
going to move forward / up. How could it not move if it isn't secured?

Yeah it may "work" w/o being secured *under* the belts, but then it's no
better than wearing a "donut".

Yeah, that would be nice. They always talk about safety, why not show
how the HANS works while they're at it? They talk about everything else
a million times.

I don't see how. It would lift up in the back and simply slide over the
shoulders.

Can you find a site that says the correct way to wear it is over the belts?
