Okay...... NOW I GET IT!...... if the driver doesn't go fast enough, you put it over his head and with a lot of speed and force, raise and lower the top lid..... he will be wishing that he had experienced a HANS device in action rather than go through that again!

There is a unit sold by a company called ISAAC that connects to the shoulder straps and is claimed to work effectively with ANY seat angle ..... it is NOT SFI approved though - due to the fact that is does NOT release with the release of your safety harness- it requires extra pins to be pulled. I sent an email to Lee Kennedy and Kiwi Steve asking as to the SCTA-BNIs interest or inclination to allowing its use. I have, to date, received no answer so I assume that it will NOT be acceptable. But see links below anyway. There is an interesting video clip embedded in the first link showing side by side testing with a HANS device. It appears that the shoulder belts slip off the HANS device during the crash simulation:


Had a discussion about this with a few folks and it sounds like there are enough SFI rated head and neck restraint systems that fit a multitude of applications available now that there is really no reason to accept a non-rated device except in the most extreme situation.

I have to agree with you on that point Nathan.... since I posted that, the "Defender" has been certified and the DJ Safety device shown on thier home page is, apparently, also accepted by SCTA with SFI certification pending. The DJ device looks like it will cover applications which are more "laydown" .... I am at present waiting on parachute info and an answer to some questions about their new head and neck restraint. If it looks like info I should post, I will do so.

The problem I have is that many of these units are different by design and wish there was a way I could try a few to see what works best for my car before setting down the coin.  

I get that some say they are for different seat angles and whatnot but that doesnt always mean they are better for getting out of the vehicle.

I would rather be able to exit the vehicle and sacrifice comfort if need be.

Looks like I am going to have to roll the dice and hope.

-stupid safety stuff anyway......

38.1 SFI is the current spec for HNR's   ISP is a seat manufacturer, not HNR's... they may however sell HNR's and I think the partner with Safety Solutions,,, makers of several models of 38.1 HNR's and some darn good seat belts too.

Here is link to ISP

Gentlemen,
38.1 spec is for head & neck restraint systems. 39.1 spec is for stock car seats.

One question--- if a certified head & neck restraint system protects the helmet from sideways motion in a crash, why is the same thing required on the chassis (lateral helmet restraint tabs)? Is this a case of "belt & suspenders?

The real purpose for the H&N is forward motion, not side to side. Although the 38.1 specifies some side to side restraint, it is forward motion arrested or absorbed by the H&N that stops the seperation of the base of the skull.

The seat or chassis is to have the side motion limit padding.

Thanks, John. It seemed like some H&N restraint systems were claiming that they also prevented side-to-side motion so it looked like duplication.

Nathan,

I have heard rumors that the ISSAC will be accepted even though not 38.1 certified.

Care to comment?

John, let me ask you this: do you think the SCTA will start accepting SFI type seat belts or SFI type fire suits?
