Are you referring to a sternum strap? I didn't know harnesses had them. It
would be a nice addition with a Hans device since the belts tend to ride off
the edges. I also like the idea of 2" shoulder straps.
I agree about the Hydrogen Embrittlement--what nonsense! You need a high
hydrogen environment (we injected Hydrogen into the primary coolant systems
of pressurized water reactors to remove free oxygen--with the highly
energetic gamma field the oxygen combines with the hydrogen nicely) or a
very unusual form of welding, or a runaway cathodic protection system to
even _think_ about hydrogen embrittlement, and then it's only likely to
occur if the part is under constant and very high tensile stress. It's an
unusual condition, and if you leave the parts alone for a little while in
ordinary air and room temperature the Hydrogen diffuses out and the parts
become ductile again.

This is what I did for my last set of seat belts -- Bill Simpson's new
company. Since I was previously using Simpson Seat Belts, I mailed them to
Impact Racing and they used the metal components, costing about $55.00.
You may want to carefully measure the distance your shoulder harness has to
reach back to the mounting point. By the time I got all the recommended
belt loops through the mounting attachment, my Stermen Strap is a little
high. You do not want this thing up around your throat. You might want to
special order slightly longer straps back from the Stermen Strap.
Apparently SCCA has not yet force the requirements of not reusing the same
metal parts. Some clown wrote a sizable technical article in "Sports Car"
about hydrogen embrittlement of the metal parts. I brought up this subject
at a Steel Cities Region meeting.
Hydrogen embrittlement is a Nuclear Reactor term. It is the concern that
hydrogen embrittlement may occur in the pressure vessels of nuclear reactors
over a long period of time. All of these pressure vessels are now over
forty years old, go through many heat cycles, and are in a highly
radioactive field.
Our seat belt buckles will be around long after we are all shoveled under,
unless they are thrown into a melting furnace.
