The HANS specific harness’s have narrow belts where they run over the HANS device 
The hans device is ‘supported’ or however you put it by the harness’s. Some of the scroth harness’s have a ‘device’ which consits of a secition on one shoulder strap that ‘gives’ in the event of a crash. It is to stop you submarining under the harness lap strap. These features are not compatible with the hans device, presumabley as one shoulder strap moves/gives so doesnt hold the hand device solid.

The same with the seats as well, they all look the same?
I think HANS seats have a little more space behind you head, as the HANS sits behind the helmet, the pad with HANS on it, on the 260cup cars comes off to provide the space I think
That at least makes a bit of sense to me, I would just change my driving position slightly to accomadate it
Useful to know thanks
Hans does require the harness to have specific angles of “approach” to the shoulders to ensure it remains in position at all times … I found the Exige sports seats had holes too far apart so mods or a new seat are necessary.
The whole set-up must be correct if it is to work properly.
I hope I never test it.
If you check out the HANS website I am sure it explains it all.
Hi … As a long time Exige owner and proprietor of
www.msar-safety.com please give us a call to talk about Hans / Helmets / Seats / Harnesses and positions. We are the UK agent for Schroth (maker of the Hans and harnesses)and have a London showroom. Remember the new Snell 2010 helmetes are just being announced so there will be an even greater choice now.
This was correct a few years ago but all ASM harnesses are now homologated for use with Hans.

The seat makes a difference for sure, the Motorsport car doesn’t have a Hans compatible seat which leaves me with neck ache because i’m hunched over a little!
It took me a while to get used to the Hans, i hated it at first, but after seeing a few case studies, i wouldn’t race without one. Must admit i use a cheapo open face helmet for trackdays though.
So looking at your site you mention “Lotus” Schroth with ASM same as my present harness BUT what do I replace it with to comply with HANS requirements ???
PS just noted your last post saying ASM is OK.
Seems you do not need to replace it… Looking through the other posts on the thread there is mention of seats and seat position … The seat position in any Elise or Exige is very upright and there is not much space at the headrest to allow for the extra sapce that the Hans and Helmet takes up. This does mean that a drivers head can feel pushed forward. The easiest fix for this is to add a little bit of rake to the seat which dependant on the drivers height can help. Hans friendly seats have the headrest either dished or set back. One note for taller drivers though is that these seats will not always go back as far as stock seats as the headrest can touch the bulkhead.

Where is you London showroom? HANS is one of the things on my list for next year along with a new crash helmet
Here you go, mate:
Cheers Mr P I’ll pop along over the winter when funds become available…
I borrowed a mates to try Ade but as previously mentioned it pushes your head forwards with the standard seat. For me it was un workable, too uncomfortable.
