I'm starting to think about a pair of short arms that swing down over the
pilots shoulders and lock in that position. The idea is to provide an
additional, robust restraint to prevent the pilots head from hitting the
canopy. Opening the canopy would release the locks so the arms would
spring
up and back out of the way.

Wouldn't a bicycle helmet be much simpler and lighter?
