Yeah, that's about right.

Post HANS device in closed-top car?


Anybody know if this can be used in cars such as ours?

One wonders why rallyists don't use this as well. Does it limit head movement too much, such that it is only suitable for the low yaw angles of track racing?

This was discussed on Rally-L and SpecialStage where the rally folks hang out.

The big issue is that it anchors to your helmet. Rally drivers are frequently taking their helmets off for transits. I don't think anyone would tolerate the perceived entanglement of helmet-HANS-belts.

They also priced it at $1275.00. Get real! It's like when drug companies come up with the cure for a disease but no one with the disease can afford it.

Acutally the price depends on the version. The original version is $875, while the most expensive version is $2000. I'm thinking about getting one for racing. After all, regardless of price, how much is your head worth?

Please, spare the "$5 helmet for a $5 head" hyperbole. As I'm sure you know if you race, EVERYTHING is a tradeoff. If every available decision was made for maximum safety, you wouldn't be able to afford the car and it would go about 20MPH.

I was referring to the closed cockpit version, since we're talking about rallyists.

If there was an economical, non-motion restricting device that would reduce the head motion in a rollover or other impact, I'd sure use it. HANS ain't it.

I think they are approved for use in "closed cockpit" cars. I just heard two nascar teams will use the h.a.n.s. device this year.

Actually, the original version can be used in closed cockpit cars. I forget the guy, but there was a person using the original version in Trans-Am last year. The closed cockpit version is for situations like NASCAR where there aren't any doors and you're going in through the windows. I thought that most rally cars still had working doors.

I do race, and I do understand the tradeoffs. If you don't feel like using the HANS device, that's fine. I will, because I feel that the extra safety is worth the cost.

remember one thing..in rallying how much of the time do you spend looking out the windshield?? half the time you are sideways and looking through glass that isn't right in front of you i.e. sidewindows, pass side of windshield, etc. you get my point you can't turn your head to see what's beside you let alone your co-driver!

if you are worried about it. get a neck collar. it is a horseshoe shaped piece of foam that you wear under your helmet. it acts as a shim between your head and neck. it stops alot of neck injuries and allows you mobility

Since I've not worn a HANS device attached helmet, I can't comment on how they limit motion. The neck collar is a nice compromise though. I've noticed by wearing one that I seem to get a better feel for my car since I'm not so busy leaning my head over in turns.

As far as alternates the the HANS device, I believe one of the racers on the wheel2wheel mailing list has put together some plans that are similar to the HANS, but much cheaper. I'm not sure how well it would work in an rally environment, however. I've got the plans somewhere if anybody wants to take a look at them.

A neck collar is NOT a replacement for a HANS! A HANS is designed to keep your head attached to your body in a high speed crash. That's all it's supposed to do. Many of the deaths that occur in CART, F1, NASCAR and other forms of high speed racing happen when the body is held in place during a high speed crash by the racing harness and the head keeps going due to inertia, which is increased with the extra wieght of the helmet. The skull is fractured at the base and detached from the spine, and......you die or are paralyzed for life. Keep in mind that kinetic energy KE=1/2(mass)(velocity)^2. So the energy goes up exponentially with the velocity. A 200 mph crash into a concrete wall is a whole lot more violent than a 30-50 mph sideswipe into a tree. I'm sure the HANS could save lives in rally racing, but it's much more critical in high speed (150 mph+) racing. That's why CART and F1 are making it mandatory this year.

My im pression of the HANS device is that it does very little as far as limiting the (necessacary) movement of the head. It SOUNDS like a great peice of equipment, but then again so does the flux capacitor.

I guess we'll just have to wait for someone with a spare 2grand to test one out for us.

From what I've seen on Speedvision, the difference with and without the HANS in a high speed crash is very significant.

I'm probably going to get one later this year. Of course, I'm probably going with the original version if I can. For most racers, I'm sure the basic version is enough if it fits in the cockpit.
