HANS device

Some statements illuding to hans lateral funtion are not out of line. sled test 30 degree offset crashes show good results. More than that and the benefits fall off. That is one reason that the big boys like nascar and F1 use basically a full containment seat. Such seat designs enhance hans function. Not only is this a verifiable fact for any who have access to SAE.org papers but I unfortunately have personally tested the device and reaped the benefits of not only the hans but a full containment seat. I'm a believer.

 

As BillyBob wrote, the more lateral impacts are going to require a seat support for your head.

Are your getting this? Have you thought about the R3?

 

R3 does not provide anymore lateral protection as I understand it. But it does provide function even it the shoulder belts come loose and may even provide function with 3 pt belts that instructors see in many newbie cars learning in a DE environment.

R3 is just Apple not the 800lb gorilla MS. Everyone understand the work arounds for HANS including the need or improved fucntion with full containment seats. Also remember to use side nets left and right. They are your last line of defense and have proven invaluable especially if you are not using full containment seats. All I can say is sidenets, sidenets, sidenets, sidenets! I think you get the point.

 

tell us about your little test...pic please.

 

Lets just say my new car number is 88. This way you can read 88 if I am upside down! It was not my fault by the way. I got punted by a P-BUG FISHBOWL!

Since this thread has been brought back from the dead and on the topic of 'full containment' seats, I recently raced (not tested!) this seat:

Quite honestly, this is the best racing seat I have ever tried. I'm spending next weekend in the Sparco ADV, which will most likely be installed in a race car at the time. Details to follow.

 

Lajoie makes excellent seats. In fact they could be the originator of full containment before it was called that. The Lajoie could be my next seat. I crashed a custom ultrashield road race supperseat about the same price. The problem I found was that the rib support dug into my ribs. After my accident I ached for 2 months. I bent my seat about 4 inches dispite firm mounting! If you look at the lajoie their treatment of the rib area is superior assuming you stay in your belts. I'm a big believer in seats mounted to cages not floors or oe rails. My belts did not slip in my crash due to a firmly mounted seat nascar style. This will also improve HANS function if you use one. My problem with sparco is it is a plastic seat and you can't drill them and firmly mount to a cage. You only have the 4 seat mounts on the base. I love the comfort of sparcos however and I do admit to using a sparco circuit in my dual use car. In fact I used it today on track. But soon that dual use car will be converted for full race. Maybe I'll see Rob in T-1 or ST2.

 

One thing gone unsaid in this thread is that if you are NOT using a harness, the airbag provides the same function as the HANS and is very likely just as effective. The reason you need a HANS when you have a harness is because the airbag is now ineffective.

Instead of "out of luck" I would use "it is unnecessary".

 

Whatever you say. I guess that's why we see so many airbags in racing cars.

 

Sorry...no way. You are mixing systems. Safety is a system and race sytems work differently than street sytems. It has to do with the compromises that are needed for street vs. racing.

By the way in the old days the driver hit his face on the steering wheel. BSF was prevented. However, I would not call that a safety device.

 

Wow! Thats one of the stupidest things I've heard in a while.

 

The FIA studied airbags and determined them to be just as effective as HANS devices. It is a public report, go find it.

EDIT: my bad, it's not public, it costs $11 or something. but google for 'FIA airbag' will get you the abstract.

 

That is absolutely correct! And it is the harness requirement for racing which necessitates a head and neck restraint system. The HANS and the harness work together.

 

Jesssusschrist FBB, is there a thread on this? When did this happen, and is the 348 toast? Any in car video? I'm going to MoSport in July, and I hear it can be wicked if your not careful. I'll remember this picture...

 

Well you can "remember it" but there was really nothing to be learned from it. I was just in the wrong place at the wrong time and dispite all the fool-proof stuff we try to do they always make a better fool. I am very extreme with safety gear and safety set-up and did a huge amount of homework. I'm still here so it paid off. With lesser gear I could have ended up like Christopher Reeves or worse.
