6D's Response To The Helmet Technology Race 4

In 2012, 6D put rotational energy management on the radar of the motocross world. Since then, almost every major helmet manufacturer has developed, included, and/or adopted some form of safety technology designed to address rotation during an impact. Yet, with so many different systems out there, each using different testing procedures, how do riders decide which is best for them? Here is 6D's view on how to best protect the head and their take on other technologies on the market.

Good job Klinger, I learned some new stuff. With AB having his helmet argument with the NFL at the Raiders the timing for something new is very interesting.

I've known Robert Reisinger for a long, long time (45 years!) and have to say that he never fails to impress me with the depth of his engineering knowledge. Well done and I wish him continued success. Hopefully 6d can make a difference and save some lives over at the NFL.

The extremely difficult thing with he nfl is that much of the problem is repetitive small brain traumas. Better helmet will help but these are generally very linear forces which is not where 6Ds technology shines above other technology. But not only small repetitive brain trauma from helmet bashing and crunching, but also often the trauma can come without head contact. With large bodies travelling at high speeds towards each other with great shoulder padding, the force of the impact causes massive brain deceleration without even contacting the helmet.

To me it seems like maybe a solution is to remove plastic covered shoulder pads to limited impact speeds, coupled with modern helmet technology

d = (vf - vi)/t

d = deceleration
vf = final velocity
vi = initial velocity
t = time

I'm no physicist but I would love for one to explain how helmet technology effects any of those variables.

Helmets are designed to protect the skull not the brain. I don't see how the brain can be protected under rapid deceleration, or from any movement at all.
