Hans Question - Page 16

Well said Darrell although I cant get the link to work.
I have been following this with great interest, I have also done some searching on the net and have found a large amount of research and images to back it all up. Many images of front on impacts and not the angle impacts that are talked about.
Having looked at the HANS site there are 4 devices (angles)available but they do say that it is very uncomon for people to use the two extream devices meaning there are only two that most people will use (one for single seaters and one for saloons)
Also someone mentioned about checking the numbers one the mounting and the device to see if they match, from what I have seen this is just checking to make sure they fit, you wouldnt try and put a 5mm bolt into a 10mm nut would you??
I am a supporter of the HANS and would like to see it used more, as a scrutineer I am happy to see that there are many more drivers using them. Although I am not in favour of making it mandatory straight away but would like to see it being bought in over the course of the next few years, and it may also take out some of the BS standard helmets that have been around for 20 year but that would be for another thread.
As has been said, all the people who say they dont work please give us links to the information that you have. If it is just hear say dont bother because therre is no point giving us information that has nothing behind it.

Thanks Jim got that now.

JimW you've summed up my argument completely:

"Life is not safe, just chose where you want to take the risks."

brickkicker · 17 Jul 2006, 20:21 (Ref:1658562)

Well this seems to have gone quiet now. Is that because no one can offer any evidence agains HANS?

Al Weyman · 17 Jul 2006, 20:36 (Ref:1658576)

No everyone is on holiday:-)

I was having some neck problems in longer races, so I've been down the gym working on my neck strength and building up my "traps". Now my HANS device is too narrow and digging in my neck

Anyone got one that a bit wide for them?

JimW · 26 Jul 2006, 15:57 (Ref:1665099)

Don't know how many of you have seen an article in today's motorsport now! magazine from the MSA for licence holders ?

There is an article in there about the HANS device. Pity the author not only knows nothing about basic physics but displays that by making several howlers. Confuses speed with acceleration and force with acceleration. Gives examples which confuse time with distance and then tries to draw useful comparisons between the two examples. Confuses potential energy with kinetic energy. And he thinks that a road car lap-and-diagonal harness displays anti-submarining characteristics.

Presumably written by someone who failed their 'science' GCSE and went on to do a media degree.

(Nothing wrong with either but don't try to deploy scientific arguments unless you have the basic understanding to do so or have at least listened and taken notes when someone competent explained things.)

He goes on to talk much more interestingly about the practicalities of fitting one and comfort factors etc.

Regards

Jim

Anyone got any comments on this rival device here http://tentenths.com/forum/showthrea...14#post1665114

Chris Y · 27 Jul 2006, 08:22 (Ref:1665688)

Well, it does look as though it is capable of a little more 'protection' than a HANS. For example those wings on the side look like they could be quite handy in a side-collision.

Also, the fact that it doesn't use tethers looks good from a driver comfort/visibility angle.

It's also cheaper than HANS, which is nice

Looks like a bit of a faff to get off, but probably no more than HANS.

However, I'd like to see a bit more of the research put into it, and obviously it would be nice if there were a few more distributors in other parts of the world, so that the device could be tried on, etc.

Al Weyman · 27 Jul 2006, 19:29 (Ref:1666129)

Maybe with new products emerging and healthy competition (and I would wear one of these if proved effective especially at the price and no mods required to my cars or helmet) then that is even more reason not to mandate and leave it to driver choice.

Notso Swift · 27 Jul 2006, 22:52 (Ref:1666301)

I note that with Australia, the ASN has never used the word "Hans" when it comes to the (future) introduction of "supplementry head restraints" However, I was speaking to the Manager of Tech on the weekend (who also sits on the FIA Tech Commission) and he said he was doing some work with the Manage of Safety and he did say they Hans would be used as a benchmark for any other product.
Hoopefully that means thatthere will be some options (world wide) if this sort of thing is mandatory

Update on the Ring crash: see post 334 and earlier ones.

our man did his first race again last week with the Mini. The championship scrutineers returned his original (crash) Hans to use it again.

When he asked if any (hairline fracture) damage was found, their reply was: errrr.
And what did DMSB say, or FIA, he asked. Reply: errrrr.

To be continued (again). Sort of boring, innit?

Slightly different problem I came across with my HANS device last weekend...

Just after going out for practice at Oulton Park my bonnet "popped up" under braking. Thinking that the catches hadn't been done up properly I pulled off the track into a chicane cut-through and the marshalls kindly did up the catches for me. As I went to rejoin the track at the exit of the chicane I realised that, because of the angle of the car, I couldn't see in my mirrors if anything was coming. The obvious thing was to turn my head, but because of the HANS device, I couldn't do that enough to see either. I looked over to the marshalls, but they had all returned to their posts. They weren't making any gestures at me, so I assumed the track was clear and pulled out.... right in front of another car (sorry Dave/Loz). Luckily he missed me, just, but it could have been a big accident.

Obviously, thinking about it afterwards, I should have called a marshall over, explained the problem and asked him/her to see me out. Easy to be wise in hindsight though. Just wondering if any of the marshalls out there actually take note of if a driver is wearing a HANS and allow for his restriced view when they are dealing with an incident?

greenamex2 · 20 Aug 2006, 13:51 (Ref:1687362)

I've had this to.

In fact just pulling out from some pit lanes requires considerable care and faith in the marshalls. (No offence to the marshalls but I nearly killed a Caterham driver when a marshall screwed up at Lydden so I prefer to err on the side of caution).

Yes, when you pull over near me.

Seriously, as I know the problem, I will always tell the marshals to assist the driver if he plans to drive away again, or even help him getting over the tyrewall.
Ever tried that with Hans on?

R59 · 20 Aug 2006, 18:00 (Ref:1687563)

I think this subject needs to be brought up with marshall's training days in the future as more and more people are using HANS.

I had a spin at Druids yesterday, and I couldn't see much of what was coming. I had a good idea that I would be in the clear as the tail ender had just gone through!!

As for getting over the tyrewall - you have to adopt the "high jump" method, ie: leap over backwards and hope someone can catch you!!

Al Weyman · 20 Aug 2006, 18:42 (Ref:1687608)

Don't you guys have wing mirrors?

greenamex2 · 20 Aug 2006, 18:58 (Ref:1687627)

Yes, but depending on a number of factors you can have blind spots. And these can be made worse by not being able to move your head a massive amount.

Ask anyone who looked in their mirrors and then knocked me off my motorbike anyway (there are many!), and then shove a head restraint on them that would probably be illegal on public roads!

How would they know especially if they are watching saloons? An opportunity for another sticker, signifying HANS use

I have not had the vision problem but have thought that it would occur when trying to regain the circuit. Been wondering about fitting one of those hal metre interior wide mirrors used in the WTCC cars, which I think that I now shall.

Triple post, someone has a clicky finger

And he goes for the hat trick!

Yes, of course. My mirrors cover an angle of about 30-40deg either side of directly backwards from my car. With my HANS on, I can look about 90 deg sideways but no further back. That leaves a good 50 deg of blind spot both sides. It's not an issue when I'm on track. Lets face it, you'd have to be pretty stupid not to know if you are just overtaking someone, or if someone is trying to overtaking you. It's completely different though, if you are standing still trying to pull out into traffic, and the oncoming cars are in the blind spot.
