Clay;
Yes, it does look a bit like what I had in mind. I'd anchor the
cylinders to a fixed, wearable structure something like the HANS.
The crash test video results look like their damping is a bit on the
weak side. It looks like the dummy's head rotates forward more than I'd
like to see.

Hey Neil, looks a lot like your idea! My only "issue" is it looks like
you have to pull a pit pin on each side to disengage the cylinders. On
some of the tight fitting cages in LSR I'm not sure you'd have room to
do that.

<Some of the Hans alternatives look pretty scarey . The Hans restrains
on a
horizontal plane at the CG of the drivers head . The others I saw ,
maybe to
get around the Hans patent , have straps that anchor at a lower point so
foreward on the head presses down on the neck .

Has anyone looked at the Isaac device. It appears that it hooks to the
shoulder straps, has cylinder dampeners that allow head movement, but
restricts on quick movement. http://www.isaacdirect.com/ Take a look
and
tell me what do you think?
