Retrofit? You have a design that makes a single release point?? Both pins are pulled at the same time??

Wayne,

No. Technically that would not satisfy the single release requirement; you would have two release points.

I'm referring to a change in the Isaac belt connector. Rather than capturing the belt with the mechanism, the belt slips into a "C" shaped component. You could either disconnect at the helmet as you do now, or drag it out the window, looking like a human TV antenna.

BTW, this would not affect the performance of the Isaac system in controlling tension loads, but the increased friction at the belt connector would slightly increase early compression loads. We crashed a similar design at Wayne State so we know it's very safe.


Kirk,

You seem satisfied with your beta-tested, Enduro Spec model. What length would you recommend for the lanyard? We can have them made up in time for the new season.

Ok, thanks. I'm purchasing new belts this year as well. Any special considerations I need to know about with regards to my existing issac, or the possible retrofit issac?

Hey guys (and Gregg) Still looking around at H&N devices and checked out the LFT R3. I was just wondering what opinions anyone had on that system? Has anyone got one?
I'm going to borrow a HANS for this weekend at Fontana.

John,

See if you can borrow an Isaac system also. A large portion of our SoCal customer base is comprised of SCCA members, so you should be able to find an Isaac easily.

The numbers on the R3 are pretty good. (Look for neck tension values. The rest is salesman speak.)

The R3 comes in different sizes/shapes to accommodate different seat angles. This may or may not be an issue for you, depending on the cars you drive. Same with a HANS device.

Whatever you try, make sure you can get out the window.
