Here's some discussion from a Czech guy who has some relationship with the Skoda crews---I have written him in discussions of modern LOOOOOOOOOONG travel suspension, and he had "Only a small file of xx events spring set ups and will look for more complete info"eye popping smiley and he travels around to events--and as he says, its a small community (and they are much more social people) so he is in the thick of things:

Another one who suffered this kind of injury after the HANS was brought in. Those were very rare before. Here we had like 20 cases of broken lumbar vertebrae in compression shocks (such as hitting something from below, going to a ditch, big jump etc.) since HANS was introduced and almost none before.

The device is used in all forms of Motorsport and even BMX and Mountain biking downhill. For the price vs safety benefit you would be mad not to wear one.
You misinterpret what Mirek saying. For other kind of motorsport, Hans device has proved to provide extra safety, although in rallying we have plenty of examples as Mirek noted that it caused additional injuries that would not have been observed if HANS was not use (maybe?). So it's contribution to avoid injuries in rallying is a bit questionable.

Btw is Kosciuszko's injury also related to this?

- Even before neck braces were introduced to the sport , incidences of Lumbar injury and fatigue were higher than cervical injuries.


- Neck braces have reduced cervical spine injuries hugely but they also reduce the severity of post race fatigue and pain that crew suffer during any event. Especially co-drivers , their heads are down a lot and they have nothing to hang on to like the driver.


- Crew fitness has a huge part to play in the bodies ability to cope with vibration and shock. Most amateur crews have marginal fitness and strength compared to a professional driver . A neck brace would be even more important I would have thought.


Lets face it your head is doing a great impression of a bladder on a stick.

There was a months long investigation done by our driver's association in co-operation with number of specialized doctors. As a result the association asked our ASN to change status of HANS from mandatory to voluntary as they found direct connection between the use of HANS and the new phenomena of broken lumbar vertebrae after HANS introduction (You are wrong in Your assumption that this kind of injuries was frequent before - it was very rare). The request was also directed to FIA. There was no result at all so as a next step there was a petition of drivers and co-driver's against the obligation of HANS use. It was signed by some 200 drivers and co-drivers but the result from ASN was again zero.
Only repeating of same phrases like You do.

Nobody denies very positive effect of HANS in case of frontal impact but on the contrary to circuits most of rally crashes are not frontal ones.
Anyway if somebody wants to use it on voluntary basis, no problem.

Fact is that to make HANS mandatory in all events run under FIA rules created demand for thousands of devices and that was a huge business. When that market was filled they put HANS into cross-country events where it has even less meaning, especially for truckers where it also limits side-visibility which is very dangerous when driving close to "small" competitors such as buggies or even bikes. I have never heard any positive word from cross country crews about HANS but a lot of complains.




Anyway You are reported for constant infractions. You don't need to reply because I will not read it.

Obviously a man of great patience.

I don't see the mechanics of how a HANS could cause lumbar vertebrae injury in a vertical impact.

Vertical impact is one of those things that make me nervous. Years ago there was a show that talked about injuries and deaths in light air craft crashes due to the vertical impact more so than frontal and they were working on a seat with a suspension to absorb the impact. I've seen a guy die in a suspensionless drag car when it rolled onto its side and hit the wall. Once our car's suspension is out of the equation, there is nothing keeping your spine from getting all of the impact.

Seems to me it would be the harness keeping you upright, though. How would the Hans play a part in that direction?

One of the heaviest and densest parts of your body (with certain members of this site providing wonderful examples of the latter) is your head. If your neck is held straight, the only place for the sudden downward force (provided by your head's inertia when you land after a jump) to go is into your spine. If your neck were allowed to move, some of the force would be mitigated.

At least, that's the theory.

Re: WRC Deaths
August 25, 2013 09:14PM
Exactly. As the person arguing with Mirek pointed out, helmets increase cervical fractures (due to added mass to the head). But they save more lives by being, well, helmets, so there are retained. H&N devices also have downsides, such as taking the flexibility out of the neck. The question is not whether H&N devices have ANY downsides; the question is whether they prevent more or less injuries than they contribute to. This could easily depend on the type of racing, but it's not a slam-dunk in either direction, given the data we have right now. And a broken neck is a tad worse than collapsed lumbar vertibrae, so I see the FIA's point.

Prius in the left lane doing double nickels (his speed limit is 70.. Traffic moving at 75).... I roll up behind at 65.... Woke some shit-head the f___ up.... OH SHIT>>>>> THERE IS A HUGE BUMPER IN MY REAR VIEW!!

I don't see anywhere in my post of my encounter of the brainiac in the Prius about tailgating it. Good reason for it dumbshit.... I didn't tailgate the Prius.... It is par for the course on your part to ASSume/SPIN the worst. Also no surprise that you delight in bringing up my having fallen asleep while driving a total of once in my lifetime.... I will run into you in person at some point. Don't be an asshole.

No, ouch to lumbar:


We don't always have to ourselves understand everything of a process to see the after effects of that process. Sometimes, like in this case, you see a single element change in the equation, then compare previous decades of observation and we see a sudden upsurge in a new outcome and we can make a good bet at the causation.

The thing I've seen a LOT of on the billions of French tarmac vids I've seen is a car--low cause its tarmac, and low means short travel suspension, bottoming rear suspension badly to the point the cars are bounced up onto just the front wheels..looks scary and is!

Now those hundreds now who have talked with me on suspesnion know I say that for conceptual purposes that front is about control and is what you feel in your fingertips "and rear suspension is what you feel in your butt".

So heavy bottoming of short travel suspension and crews forced by office drones and bureaucrats to use HANS suddenly 20 fractured LOWER backs....

Now I just had 2 spine surgeries: cervical at C5/C6 followed about 6 weeks later by surgery at L4/L4....mine weren't fractured but the disc had been crushed to nothingness and the nerves which exit the spine to power things were "severely crushed"....It was incapacitating, no-drug-really-did-anything, grind your teeth to powder pain..

I don't think in the rush to protect the assets of some guy who owns a corporation sanctioning rallies I want to be forced to use/do something that is now implicated in that kind of injury...and implicated by people with far more experience, and far more data to help them analyze things..

Looking at this photo, I just don't get what caused the impact and damage. The little TR7 got some air over the crest/jump, but they didn't go that far in the air. I am assuming those white staggered signs in the foreground are the distance markers that the WRC cars were measure against. Did the TR7 bottom out and crush the spines of both driver and co-driver upon landing?

Look how the dashboard is folded up, the left side looks smashed in. They impacted something on the driver side hard. What is that white thing to the left side of the rear of the car? Did they hit that?

Speed doesn't kill, it is the sudden stop. A sideways hit puts tremendous stress on the neck, more if the weight of a helmet is involved. There is also the risk of soft tissue damage. Lungs, heart, brain and a few other organs bouncing or being torn.

HNRs don't hold the neck solid. There is lots of room for vertical travel as well as side to side. Blaming or even implying the Germany deaths on HNRs is pretty physhic at this point.

I'm sorry for the losses, our sport has certainly had enough for a while, both on tarmac AND gravel.

Re: WRC Deaths
August 26, 2013 11:43AM
All this talk of HANS potentially causing injuries reminds me of a few years ago when Leatt neck braces started becoming popular in motocross, they were designed to prevent injury in a very specific type of crash - when the rider lands directly on the top of the helmet. The force from the crash was distributed to the shoulders and torso, so in other lesser crashes they could possibly cause collarbone, shoulder, or back injuries that would not have normally ocurred.

Motorsports are inherently dangerous and it's always tragic when an accident like this occurs but I guess my question would be is it worth potentially causing a few more lesser injuries (arguably I would say that a severe lower back injury is lesser than a paralyzing or worse neck injury) to save a few lives?

Neck braces are not required that I know of in any form of motocross, and right now it's a pretty even split of riders who wear them and riders who don't. FWIW I have worn one for about a year now and have had some pretty serious crashes with no adverse affects from the brace.

*i'm specifically talking about the HANS causing lower back injuries, not this fatal accident as it's just speculation as to the cause of death at this point.

Re: WRC Deaths
August 26, 2013 12:29PM
First off: The deaths in Germany are truly a sad incident and I feel not only for the families of the driver and co-driver but also for the volunteers and emergency workers who had to deal with the aftermath of the incident.
That is what this thread should be about.

John: You really should be ashamed of yourself for pouncing on the still warm corpses and showing the level of your insensitivity and arrogance by not uttering a word of compassion before condemning the choice of car, the crews choices on the day and then anyone who chooses to take part in tarmac rallies. Then you follow that up by spreading the unsubstantiated rumour that a spectator or photographer was also killed in the incident without so much as couching it with 'early reports said...' Nope, you heard it once, didn't follow up and assumed it was fact and repeated it as such - all within hours of the incident when information was still coming out.

In all seriousness, I think you're having some issues. The number of posts you've put online that are nothing but attacks is uncharacteristically high, and unusually aggressive. Your commitment to your ideas and positions is also unreasonably high. There is an old saying that 'if everyone around you is an asshole, they might not be the problem.' Far from being a push to uniformity, the phrase is more about being open minded and less rigid. For what its worth, when I start thinking everyone around me is stupid or just 'doesn't get it' I take that as a sign that I need to slow down and think about what's going on in my own life.

On the issue of the HANS device, I'd love to see the report from the investigation. Without seeing the method of investigation, the data and how it was interpreted it really is impossible to reasonably discuss the findings.
Did they just look at the number of incidents?
Did they do dummy testing?
Did they look at other changes, specifically shortened shoulder harnesses?

Frankly, the first red flag is that the investigation was performed by 'specialised doctors.' (Common use of 'doctors' suggests physicians and not PHds in physics, kinesiology or any other applicable field. To be meaningful, the investigation would have to had looked at the mechanics of the injury, not just the instances of it.)

If I look at the HANS device, I really don't see how it can significantly increase loading on the body in a way that would lead to back injuries. What I CAN see is that the shortened harnesses recommended for use with the HANS could restrict the torso from some up/down elasticity and THAT could lead to some injuries in the right conditions.

Like some have said, this may also be a case of a lesser injury becoming more common as a result of protecting against much more serious injuries. An extreme example would be the increase in elbows hitting door bars when they became mandatory. (And no, I'm not equating a fractured vertebra with a sore elbow - it's intentional exaggeration to make a point.)
