X-Rays on Crashed Helmets

[xsiliconkid]

Pull the liner. You would see any crushed foam. Some companies paint it black so you can easily see white where the foam has cracked.

As Paul mentioned, if there are any deforming of the foam usually indicated by what looks like fine white spider web cracks in the black paint on the foam.
If the external shell shows any abrasion, tech will fail it. You will need the manufacturer to OK before they will allow again.

Would tech actually allow an obviously abraded helmet if accompanied by a note from the mfg? How would they know which scrapes are pre-note and ok vs post note and not, etc?

I had my buddy at The Service Pavilion check mine out after a crash. He definitely won't keep it. My guess is that he will say that helmet is done, but you can give him a try: http://www.theservicepavilion.com/. Rob used to work for Arai and started his own gig in 2002. Good luck!

just talked to Robert. Sending him the helmet next week. This is the info I was looking for. Thank you

ps the way a helmet works is all about slowing down the deceleration of the head - the foam does this by absorbing the impact. the shell is just to keep the foam in place why the foam is doing it's thing..

BTW... this technology is coming to road helmets later this year...

I tried one on yesterday...stupid light.
if anyone watched the Dallas round of the Supercross and saw the 250 rider come down on his head and then run the last chance race - he was wearing one of these helmets...

tech is not the meta safety gate keeper - just a guide.... a lot is up to racers common sense

Scrapes and scratches don't compromise a helmet, impacts do.

The foam is doing its job and showing you that the helmet is not compromised by not showing any white spiders/etc.

Paint it and run it.

I did this with a light scrape (granted not as bad as yours) on my arai for the past 4 years until it reached the 5 year mark and I had to retire it.

Who hit you in 11a?

No idea

Which brands will be using it? Any ideas on cost for the street? 750 for dirt makes me think +1000

IMO, it's not worth finding out (on your own) whether or not it's still good.

That helmet has been crashed. End of story.

I agree with this... impacted once, its done.

This looks AWESOME. There needs to be new ideas put into safety gear IMO. The helmet was loooong overdue.

Because it's rigid, doesn't the shell also help distribute the energy across a broader area of the foam? The example I'm thinking of is a street crash where you hit your head on the edge sidewalk curb.

[fineout]

I feel like those X rays would look pretty sweet as a print on the wall.

[Paul_E_D]

The shell doesn't absorb much energy. In your example a LOT of energy is transferred through the shell at an angle. That is the exact problem this new tech is addressing.

My hockey helmet is a similar concept in design, allowing the helmet to move and flex around the head and bouncing back to form after instead of having hard a foam liner... I concur that technology like this is way over due and I like what I am seeing with this new helmet design a lot.

For a second I though I saw Ray-Ray in the title...

Back on topic!

Steve Aspland had one (motocross version) at the track this weekend. Looks like a very cool technology!

[Mr. Kurtz]

problem with Arai is they'll keep the helmet if they say it's no good.
however, i'm a bit skeptical with my findings here that they'll actually send it back regardless.

FYI, Arai will send it back if you tell them to, you'll just have to pay return shipping. They'll always ask not to if it's damaged.

the top of the line dirk bike helmets are +$800..
It will be priced to match the top of the line helmets.
