Lynn, your post reminds me of a great joke I heard a long time ago about a woman going into a tack store to buy a helmet.  She told the clerk, "I want a REALLY GOOD helmet--I've got over $100,000 invested in my head!"

 

The clerk replied, "Oh, did you have a head injury?"

 

"No," the woman responded, "I went to college!"

My point is that the materials of the helmet did exactly as they were intended--they took the brunt of the blow and responded through their own breakage instead of through breakage to my head! Had I not been wearing the helmet, this accident would most likely have resulted in skull fracture, and probably fatality.

As usual, Heidi is right!

If one had a really bad fall and your helmet broke all that means is that the most the energy of the impact was imparted into the helmet and NOT the scull. In short, sometimes it’s a good thing for a helmet to break. Think about all those slow motion “tests” on the car commercials: The car gives and disintegrates around the passengers absorbing the energy of the impact. Older cars were not designed to absorb the energy of an impact which resulted in more serious injuries and deaths to passengers even though they were wearing their seat belts. The design of a helmet is quite similar in this respect. If anyone as a serious fall in a helmet they should get a new helmet because the energy imparted into the helmet my compromise further ability of the helmet to absorb energy from another impact. Helmets are not elastic, and neither is a scull. A $50 helment can save you a $500,000 hospital bill. Makes the Geiko commercials look whimpy.
