Well, my HANS device arrived today, and very little about my set-up meets HANS's published spec for proper fitment. This despite the fact that other Lotus owners seem to be using their HANS devices with the seat/harness bar set-up I have.
I am trying to decide whether I should (a) return the device, (b) keep the device and change my car, or (c) keep the device and leave everything be.
First off, my set-up:
- Lotus Sport Seats; I am assuming these are the same seats installed in Exiges; a hole for an anti-sub strap was installed by a race shop.
- Schroth six-point harnesses (with 3-inch shoulder straps)
- Sector 111 4Tress Harness Bar.
Now, my problems (see illustrations for clarity):
- The back of the HANS touches the seat back. It's not supposed to. And I have a HANS model 10, created for the most upright seats.
- The relative locations of the harness bar and my shoulders don't give me the 1-2-inches below horizontal as defined in the illustration. FWIW, I am 6-feet-tall
- Because the inner edges of the shoulder strap holes in the Lotus seats are much wider than 5 inches apart, I can't replicate the HANS spec, which calls for no more than 3 inches distance from inner edge to inner edge.
All that said, with the device strapped in, I have sufficient range of motion, and it seems very stable and buttoned down.
Can other share exactly what seats and harness bar they are running? Knowing your heights would help too.
Thanks!
