MY 30° Scroth HANS device has the sliplock rubber on the top. I use a normal Willans 3" harness. It's comfy, doesn't slip off when I try to make it slip off, and I see no reason why they'd come off in an accident anyway because of the converging belts.
If anything I think it'll help reduce the chance of the belts cutting my neck, because the point load is taken by the HANS rather than the skin of my neck. I'm certainly comfier with it on. |

Let me put something straight here: do NOT think that belts just fall off a system in a crash. It is a well structered design that had some early "flaws" like everything.
Or does anyone think proper racing seats were state of the art contraptions when they came on the market so many years ago? The wings are just an additional help and may even disappear again if some better solution is found. If everything is mounted the way it should (Hans, belts, right angle, ...) nothing will go wrong. But then again we are in motorsport. ANYTHING can happen. |

If you worried about a HANS coming off then get the R3 Head and Neck Restrant system instead.
also SFI-38.1 Certified! |

I've recently "tested" my Schroth 30degree HANS with 3" Willians belts. Whilst not a particular hard impact, I hit a conveyor belt type tyre barrier head on at a 20-30 degree angle at a speed of around 70-75km/h. I felt the tethers stopping my head's forward movement, and an in-car camera clearly shows my head being stopped going further forward once the tether's slack took up. HANS didn't slip out of belts and didn't suffer even the slightest neck soreness.
Best investment I've made! |

They found that their design did not suite 3" belts because they were more likely to slip off than the 2" belts. However, since then, designs have been refined and modified. Neoprene has been used to create belts that don't slip, and thus they are now more happy with 3" belts. But we've been through all of this before. More than once. Rob. |

PRESS RELEASE CORRECTION - HANS DEVICE ASSERTS SIDE IMPACT PERFORMANCE
The original press release referenced an incorrect SAE paper. The correct document is SAE Technical Paper Series 2004-01-3513. Atlanta, Georgia (March 13, 2008) – Recently, allegations have been made that the HANS Device does not work in side angular impacts. This is simply not true. It is contrary to proven results. Such distortions confuse and deceive the racing public. Independent testing, supported by General Motors Racing, Wayne State University and Safety Solutions, Inc., has demonstrated that HANS Devices reduce maximum neck tensions by over 35% in 60-degree "side" impacts in a typical racecar set up (SAE Technical Paper Series 2004-01-3513.) HANS Performance Products CEO Mark Stiles said, "We are not aware of any substantial independent side impact testing on products that try to compete against HANS Devices, but we have seen competitors continually try to deceive racers with marketing spin." Stiles added, "SFI tests include a 30-degree "side" impact. The best performance we have seen reported by competitors here is 20% worse than we achieve with HANS Devices in recent tests." He continued, "Representatives from HANS Performance Products, Hendricks, ISP and The Joie of Seating, did observe some 90-degree "side" impact testing conducted at the end of last year by Delphi for NASCAR. We all witnessed how the HANS Device worked as the tethers grabbed the helmet." The best side impact performance is achieved with an SFI or FIA approved head and neck restraint, a good harness system, seats that have hip and shoulder support, and a lateral head support system. The latter can be built into the seat or achieved using special side nets. |

Superb. Makes it an even better purchase!
I'm of the opinion that anyone who DOESN'T wear a HANS device is a fool, although in a lot of case they are simply not affordable, so I'd let them off (as long as they want one). |

This wouldn't be a reaction to Mark Porter's crash at Adelaide? It was rumoured that the HANS device wouldn't have done any good for him in that accident.

The 'Sports Series HANS which is available in the states for $695 Dollars ( about £350 ) is just about to go into production under licence by Shroth in Germany. I believe Shroth are dictating the selling price (mmm - wasn't too sure that was legal) at 550 euro plus vat - Thats £428.93 at todays exchange rate plus vat = £503.99.

Same here in the States. The prices are FIXED. No vendor can sell them for more or less then the MRSP. Not sure it that is legal here either. |

Any differences between Shroth or Stand21? Any links to the cheapest places where they can be bought from?

With the flip ups, does that make it a Stand21 type, where the Schroth has slipstop. There are probably other makes that I don't know about too.

It's a bit cheaper, and if it's Stand21 then yes, it'll be fine. They work best with 2" shoulder straps, so they sit in the groove, retained by the lip, but people have used them with 3" without issues.
Spend whatever you save on a better helmet though. |

If its got flip ups its either a HANS device made in the US to the Dr Hubbard design or its a Stand 21 version made under licence in Europe. Essentially the very same thing. I was told sometime ago (admitedly by Stand 21!) that the Schroth version does not have the flip ups as it is a copy of an earlier HANS design (note, a copy and not a licenced design). I was told that the Stand 21 version is the real deal whilst Schroth can't do a flip up version because it would infringe patents. Not sure how accurate that is but there you go.
