wow, hat does sound bad. For that to happen when he had a helmet on he must have banged hard.
I don't know what style of helmet he was wearing, but they're generally a bit over-rated in this regard--made for low-speed, low-impact collisions. There is also some evidence that they may influence falling behaviour and make head injuries more likely. However, the debate will probably rage on forever. :)
