EXCELLENT article (accessible by clicking on the first blue-texted line above)!

Don't want to hijack this thread; rather, to commemorate a college professor of mine whose research contributes to the safety of all of us motorcycle riders today: Hugh Harrison Hurt.

Hurt and colleague researchers discovered helmets through the 1960s, with elastic suspensions (including military aviator headgear), actually produced G-forces on rebound up to twice the magnitude of impacts. The energy from initial impact was stored in the elastic helmet components, whose elastic rebound ("spring-back energy") could injure the wearer. That's why, today, we all wear energy-absorbing helmets (often, absorbing energy by the styrofoam-like innards of our skid lids).

Here's an extract from this biographical article ( https://mtaes.wordpress.com/tag/hugh-harrison-hurt-jr/ ) about Hurt:

-------------------------------------------

Mr. Hurt was a professor of science at the University of Southern California and a lifelong motorcyclist. In an interview dated 2005, he explained his devotion to researching motorcycle accidents to the fact that he had “developed a terrible concern that motorcycles were getting a bad rap in traffic accident investigations”. After studying 900 accidents that happened in the Los Angeles area between 1976 and 1977 , 3600 police reports, photographing 2,310 motorcycles that passed by and interviewing 505 riders, Hurt released his findings in a 1981 publication that became known as the Hurt Report. His most notable finding was that wearing a DOT-approved helmet dramatically increased a riders chances of surviving a crash.
Hurt retired from USC in 1998 and went on to found the Head Protection Laboratory in Paramount, California. He researched helmets from all manufacturers and participated in major research projects which set the standard for safe helmets and even modified the Snell standards, which was the leader in deciding the safety standards for helmets. The change accounted for head size and not an across-the-board helmet rating. Hurt stated that the Snell standard produced a stiff, hard helmet with the tendency to increase and not decrease brain injuries. The Hurt Report was discribed as “the most comprehensive motorcycle safety study of the 20th century.”

Again, thanks and appreciation for the article on helmet safety standards and certifications; just wanted to point out Harry Hurt's role in protecting motorcyclists today and into the future.
