Helmet Support Rings Do You Wear Them?
�
�
Hey guys, I am just getting all my safety gear together for starting to co-drive in september (first event is wild west! :banana:).
I was wondering if people suggest using a helmet support (the rings that go around your neck).
Also does anyone wear them with an openfaced helmet? I have a openface Pyrotech SA2005 helmet.
Thanks for your help.

do not wear one of those little donut things they are more harm than good.

HANS!
Like noted above, these will put a bigger load on your neck then not having it there.

I wear mine when karting, but not when driving at the track.
I don't understand why wearing a neck roll/helmet support would do more harm than good. Please explain. TIA.

As I've seen it explained, since it doesn't constrain the head and helmet, it just moves the pivot point when the helmet snaps forward further away from your torso. That increases the tension in your neck, which is bad.
If you're concerned about spinal cord injuries, get a H&N restraint (Hutchins, HANS, etc.).

It offers leverage for the helmet. So if you were to get into a wreck the helmet has a little lip that it can lean on and cause more harm.
No ring == helmet points down
ring == helmet leans on ring and excerts OUT pressure, which causes seperation of neck from body
Hans/Isaac == helmet has limited range of motion away from body for the win

Well, they don't have to worry about spinal cord injuries due to the body being constrained and the head not.
They DO have to worry about spinal cord injuries from belly flopping into the steering wheel, attempting to conform to the shape of a haybale or tire stack, getting t-boned in the throat by their own kart, accepting another's kart up the coccyx, etc.

Are there any tests and reports I can read about this?
This is the first time I heard about this. If the neck support collars are so dangerous, why are they not banned from use in motorsports?
I feel that the collar prevents the chin from impacting the sternum that causes hyperextension at the back of the neck. The helmet is stopped by the collar and the head stops moving forward from the chin strap.

A factor that hasn't been stressed in some of the above posts is the density/compressivity of the helmet support ring in use. At one extreme, a solid non-compressable ring would serve as a "bump stop" that would turn the ring into the fulcrum for the helmet "lever". In this scenario, your only variables would be height of the ring and point of helmet impact to determine leverage. At the other extreme, a very soft, totally compressable ring would only serve as a fulcrum during the time of compression [B]at the same time that it was absorbing energy from the head/helmet system[/B] reducing the final energy at the limit of displacement by that required for compression of the ring. Diminishing energy that the human body has to absorb or delivering the same energy over a longer period of time (like crumple zones and energy absorbing steering columns) enhance safety.

[QUOTE=SubyFi]The helmet is stopped by the collar and the head stops moving forward from the chin strap.[/QUOTE]
How is the helmet stopped by the collar?
There is no part of a collar that constrains forward motion of the head.
It's not the chin impacting the sternum that causes neck injuries. It's the forward motion of the head after impact that puts too much tension in the neck.
As far as testing, I don't think any collar mfr makes any claim that their product can reduce your chance of spinal cord injuries in an accident, and it's certainly not certified as a H&N restraint.

"Made of a special compounded high-density, fire retardant foam with removable Nomex cover. Collars will absorb up to 40g at any angle and prevent neck over extension" from above pyrotect link. Thermal and kinetic energy protection are claimed. This supports my earlier post.
SubyFi, which plain round collars are you guessing to be "not that good"? Do you mean compared to the pyrotect stats?
TIA,

Compared to the round circle style of collars. The Pyrotect one is contoured (horseshoe shaped) to sit on your shoulders and there is not much space between the helmet and the collar and shoulders. You can even cut away pad material so that it fits better. It is hard for me to turn my head with it on.
I am still waiting for hard facts and not just heresay and theories on a internet forum whether neck collars cause more damage than they do without having anything for the neck. I just find it unbelievable since a lot of sanctioned motorsports require some kind of neck collar (or HANS). Are rollovers even being considered? [url=http://www.motorsport.com/news/article.asp?ID=84966&FS=CRA]How about fire protection[/url]?
I cannot believe someone's post here that neck collars do more harm than good without any proof.

Do you have any proof (marketing claims are not proof) that neck collars do anything to prevent spinal cord injuries?
I'd even take anecdotal evidence that shows two passengers in the same crash, one w/ a neck collar and one w/o where the neck collar prevented injuries?

BTW...I sent an email to Pyrotect asking if they have any test data to back up their safety claims on their neck collar.
I plan to eventually get a H&N restraint, but if I'm not opposed to buying a cheaper alternative in the meantime.
In my search, I also found this interesting tidbit:
[url]http://www.upgrademotoring.com/safety/bell_helmets/bell_pyrotech_warnings.htm[/url]
[quote]PYROTECT - BELL West Distribution does not recommend any brand of helmet restraint system. To install such an aftermarket system on any BELL or PYROTECT helmet is entirely the owners responsibility.
HANS has tested their installation hardware on BELL helmets successfully, and now BELL helmets may be purchased with HANS hardware installed at additional cost. The installation of a HANS device only on PYROTECT helmets will not void the factory warrantee,
however we make no claim as to how such owner installation will effect performance under impact.
We are aware of no other device that has undergone such rigorous testing and thus make no claims that other brands are acceptable for use on BELL or PYROTECT helmets, provide any safety advantage, or possibly might lead to greater injury.
We suggest you review the Society of Automotive Engineers paper #2002-01-3304 from the SAE Motorsports conference of December 2002 completely and draw you own, independent conclusion as to install any such a device or not. Also be aware just recently some sanctioning bodies have elected to not allow certain manufacturers devices use whatsoever.
We use our special, extra high density elastomeric contoured collar that fits down over the shoulders, is elliptically shaped and sized the same as Snell 95 or later helmets. Impact in any direction will cause the helmet to initially compress the collar, and will do so without any instantaneous peak deceleration or neck rotation.
This design limits neck extension, until full collar compression, without "snap", and should not cause neck compression, a possible serious consequence of some head restraint devices.
NOTE: We do not recommend, nor sell, round 360 degree soft foam collars that fit tight to the neck and consider them a safety hazard, causing a fulcrum point for the neck. While in large diameters they are useful off road to help support the weight of the helmet, they perform no safety function. Polyfoam will not cause measurable impact absorption.

Hmm good read. It appears to be just mostly up in the air and split on the decision.
Most likely I wont wear one because I can imagine how it would put the stress higher in your neck. I being a college student don't have $1000 to drop on a HANS device, so that wont happen for a LONG time for me.
Thanks for all the answers!

AFAIK, the original purpose of these collars was to help eliminate neck fatigue from the weight of the helmet bouncing around in normal usage, not to help in an accident situation, not to be a safety device.
| Georgethefierce | 07-21-2006 01:33 PM |
ok I don't know how safe the neck rolls are but they must do something....I never used to wear one but last year I had a small off. (tire wall head on at about 35-40 mph) the impact was enough to snap my head forward and pinch a nerve in my neck causing me to lose feeling in my fingers for a couple of months.....I was told it wouldn't have happened had I been wearing a neck roll
| Protege Menace | 07-21-2006 01:36 PM |
I think ive only seen one person if ANY wear one during a rally.
Unless you use a carved out bowling ball for a helmet you should be fine.

So far Georgethefierce's post is a point for neck collars. In the event of a crash, the neck collar, when used with a full face helmet, can help prevent a neck injury from your head snapping forward, backwards, or sideways.
This supports Fogrider's post #11:

I'm interested to know how "they" arrived at that conclusion. Analysis of crash data? Having been in a different accident wearing a horse collar?
I'm still looking for test data either way...and haven't found any.
HANS FAQ page claims that tests show neck collars increase risk, but I couldn't find the tests, or which collars were tested.

Can I wear a "horse collar" foam pad with a HANS�?
Yes. Note testing has shown a horse collar adds weight to the helmet and the head that must be carried by the neck. This increases the chance of injury. Wear one for comfort, not safety related reasons.[/quote]

Wow, after watching that video, why would you still believe a neck collar would cause more harm than without anything at all? Their baseline test looked brutal. The speaker did mention "chin strikes" as a cause for injury. With the proper padded neck collar, the chin is held back by the helmet strap.
| GarySheehan | 07-21-2006 04:43 PM |
After watching that video, how can you contemplate ANYTHING other than the HANS if you are concerned for your safety after seeing how useless the Hutchens is.
Seriously, a neck collar seems like it would be as effective as putting a bra on the front of your car to protect it in a frontal crash.

[QUOTE=SubyFi]Wow, after watching that video, why would you still believe a neck collar would cause more harm than without anything at all?[/quote]
They specifically talk about spinal extension as the major problem. The point several people have made was that the collar gives your helmet a new, higher pivot point to rotate about, causing even more extension. I'm not sure that I buy that without further proof - I'm kind of guessing that the foam collapses under any real force and does nothing but offer you a way to rest your head when you get tired...
[quote]Their baseline test looked brutal. The speaker did mention "chin strikes" as a cause for injury. With the proper padded neck collar, the chin is held back by the helmet strap.[/QUOTE]
Chin strikes as in chin hitting a solid object, like the steering wheel. Your seat belts (and spine) all elongate in an accident and you'd be surprised how easily your chin can strike the steering wheel, even when you're "properly" restrained. Even with a properly tightened helmet, as they explained, your helmet can roll off your head and expose your jaw and lower face (and at worst, your helmet can fly right off).
It's funny. The longer I am involved in motorsports, the less desire I have to do anything that is between motorsports and daily driving. I'm afraid, now that I know what I know, of taking a street car to the track and dying. I'd much rather build a cheap Spec Miata (or Honda Challenge) car, make it properly safe, and then, as a bonus, drive harder, knowing that if my car hits the wall, the parts to fix it are dirt cheap (compared to fixing my STI).

I agree that the HANS device is the best head and neck restraint currently available. Is a harness and rollcage required with a HANS device? If so, it would not be practical for the weekend warrior who just wants to track their daily driver in a HPDE. The neck collar seems to be popular in grassroots motorsport due to its affordability. If they did not do anything at all (i.e. like a car bra for a frontal collision), why are many people still using them?
My main gripe is how one says a neck collar is worse than having nothing at all. Granted you may still get injured even with the neck collar, but wouldn't it be a less severe injury than without having it? Are we looking at all the types of crashes that neck collars may be beneficial such as a rollover incident?

AFAIK, the HANS device NEEDS to be secured under the shoulder straps of a harness to work...I don't think that would require a roll cage, but harnesses are required to hold the head with the body in the harness. Someone feel free to correct me if I missed the point.

Meh.

Sorry for the delay in getting back to you. Regarding data, the only thing we have at this point is the feedback from drivers such as myself as to how functional the design works. We are looking into having the collars tested since we're pretty convinced that our collar, along with the harness being correctly mounted is an effective restraint system. The collar does meet and is labeled as such (SFI3.3 Helmet Support).

No testing to support their safety claims. I might as well buy an Isaac! ;)

For example, this weekend I instructed at an event and had 3 students plus my runs = 16 20 minute sessions per day (it is a two day event). My neck starts to hurt after a while and the coller seems to reduce the neck fatique somewhat. I don't think it would do much of anything (pro or con) in an accident were you are subjected to extremely high g forces.
