My guess is, it wasn't designed to work that way...then again, I suppose
you are gonna claim to know more than the people at HANS.
He's too stupid to understand that if you attach the helet to the seat,
there is a very realistic chance of getting trapped in the car. Not to
mention that attaching the helmet to the seat would break the driver's neck
in a frontal collision.

What a maroon. ($1)

That's gotta be just bait!

I offer my opinions, Chad, and I think my explanations are direct,
straight forward, and easy to understand; plenty good enough for most
people here.

You did not agree with me about engine displacement. You do not like
my definition of roof flap design. And, lemmie guess, you don't like
my comment on the HANS. Go figure.
You have me mixed up with someone else, I made one comment about
displacement, neither for you or agin you, and I don't think I commented at
all in the roof flap thread. I'm pretty sure you said something idiotic
about G forces in the Trulli thread though!

And I didn't say I didn't like your comment here, was just observing that
it's so obviously wrong to anyone who bothered to try google, or just read
this entire thread, that it must have been bait to get TS into another long
winded argument.

But if I was wrong about that, I guess you really are just a useless windbag
that spews out the first thought that comes to mind without a care if it's
right, wrong or just plajn stupid.

But no doubt from this response, you will back up this opinion with plenty
more ill informed posts to win tour argument anyway.

Enjoy yourself, if you find a player. ;-)

Um, no. You can explain whatever you like, dumbass. When you're wrong,
you're wrong. And you usually are.

Is that direct, straightforward, and easy enough for you to understand?

It's because you're an idiot and he knows bullshit when he sees it. You
likely have the highest percentage of being wrong of anyone that has ever
posted in RASN, and everyone knows it.

It's okay to strap your body into the seat but not your head because
you might get trapped...

driver's neck in a frontal collision.

Because your body would go flying out of its harness... LOL
Oh gawd, I know I should resist, but I'll try one serious response to you.

during a front on accident the seat will decelerate at a very different rate
to the driver and his belts. The idea of the HANS is to keep head
deceleration at the same rate as the body (in particular the spine).

So the HANS needs to be part of the body/belt "mass" so that it can match
the head deceleration to the body.

If the helmet was just mounted to the seat a persons body would decelerate a
lot slower than the helmet/seat/head, putting some level of pressure on the
neck.

I don't know how far a drivers body does move forward compared to the seat,
but I'd guess anything more than an inch or two suddenly, at 8gs, would be
enough to really hurt something in there.

Belts stretch, moron. How many times must you expose your stupidity before
you STFU?

The purpose of the HANS is to maintain the position of the head in relation
to the body, not to hold the head in a specific position. Its design
obviously reflects that to everyone but you.

But you'll continue to argue even though you're wrong, because you're stupid
that way.

Well said Chad. Much like banging your head against the wall, though, given
your intended audience.

Yeah, like removing your head from your body.

Reminds me of those Ford Escorts and Mercury Topazs that had the auto
shoulder belt with a manual lap belt. There were people that got
decapitated during an accident because they weren't wearing the lap belt.

I've considered all that and believe a head harness could be tuned to
sync with the body during each given degree and direction of impact.

I'm not saying the HANS is a bad device, or entirely bogus. It's just
that I think Vandar brought up a good question. The question is why
not, and I'm not satisfied with anything I've seen so far. Should that
make me a bad person or someone to revile and insult?

Let me ask, why are you here? Are you here to think about and discuss
the topics, or is everyone supposed to get in unison lockstep with
each other and agree with everything everyone says? Let's agree to
simply disagree in a civilized manner.

If it were as simple as attaching the helmet to the seat, don't you
think it would have been done by now? Years of research went into the
HANS before it was ready for prime time.

On top of that, it's just one more thing that would have to be unhooked
to get out of the car. Sometimes these guys are in a hurry to get out ya
know.

What you have said, in all three topics, indicates you disagree. And
each successive time you're getting more and more combative. I see it
over and over in certain people but I did not think you were like
that. It's kind of disappointing.

I think I did throw in a smartass comment or two, but technically didn't
disagree with either side. I genuinely didn't know enough about flaps or
displacement to say either way, and was having trouble following the logic
of all the argmuents to counter anything anyway. (It read like Larry arguing
with Curly about nuclear fission to me! LOL)

I did not make one single post in topic. I'm not the confused one.

And I didn't say I didn't like your comment here, was just observing
that it's so obviously wrong to anyone who bothered to try google,
or just read this entire thread, that it must have been bait to get
TS into another long winded argument.

You were calling me a troll, when all I did is give my honest opinion.

Baiting people isn't really trolling. Sometimes it's quite witty. Personally
I'd take the option of being thought to be throwing out bait than saying
something a silly.

There it is... insults, name calling. No vulgarity? In time I guess.

plenty more ill informed posts to win tour argument anyway.

To win tour argument... ill formed posts... Good grief.

Enjoy yourself, if you find a player. ;-)

Wasn't looking for one, but I guess I did find a player. You.
LOL.. well I'll give you that. But I am feeling extra chatty this morning
anyway so I was a pushover

You've got me wrong though, I'm very open minded and "like" just about
everyone that posts regularly in motorsport newsgroups. Even the ones I
don't agree with or think are trolls, smartasses or a bit xenophobic. Oh,
and the ones that write like they never made it past 6th grade too. It's the
social interaction I like, as much as the motorsports info anyway.

You're interesting sometimes. But you do seem to have been a bit "manic"
this week the way you have been so keen to argue a bunch of really fine
points to the Nth degree. Actually that's been interesting enough to read
most of too, for the entertainment value if not the content.

And as far as getting more combative over time. Don't knock a man for taking
some time to decide for myself! (and don't discount that it may be you if it
happens a lot) ;-) I wouldn't normally be combative with someone who wasn't
a bit that way themselves either.

Anyway, back on topic.. After a few mins to think about it, are you still
convinced the helmet to the seat thing is a good idea?

(oops, bloody race has started and I'm sitting here typing this crap!! Go
Marcos!)
