A "work around" I use is to press my body up against the belts. This
tends to reduce the "overshooting" that occurs when you are thrown
against the belts by negative G's, and reduces or eliminates the impact
with the canopy.

So, what about the idea of a pair of short, say 8", padded arms that

rotate

down over each shoulder and latch in place? That would prevent the

upper

body from rising and the head from snapping sideways. The latches would
release and the arms spring back when the canopy was opened.

Perhaps fixed arms could be on the canopy frame, so they would rise with
the canopy without any complications.

Another possibility would be a modified or removed seat back that would
give you more distance from your head to the canopy.

Any of these things would need careful design to ensure they don't make
other situations, like a crash, much worse.

Or maybe it's time for a different glider with a larger cockpit, or more
flexible wings!

Not true about not hurting if your head can't move.

With my chute and 1/2" of dyna-foam behind me, my head is in contact with the
hoop of my Std Cirrus on launch. To stop banging against the canopy I tend to
push my head back against the frame in turbulence. Despite not being able to
move much the vibrations and variations in force still give me a nice clearly
marked bruise on the crown. The price we pay for being 186cm. I wonder about the
tall guys though.

For what it is worth, and for those who have not had the privilege of flying
one, the Cirrus has wings like a steel truss, very little flex so you notice any
turbulence. Makes finding thermals easy though...
