New concept in helmet design?

[awa355]

This chap has come up with a new concept for cycle helmets.
I wonder if it could find its way into motorcycle helmet construction. Has probably been looked at before, I suspect.

Not really a new concept, he uses cardboard to absorb the force of an impact, I don't think bicycle helmets absorb much impact, I've had a concussion while wearing one.

It's not a new idea though, your helmet (assuming you wear a legal one) already does this, we need it because there is often far more force involved in a motorcycle crash. That's why you should throw away any helmet that hits the ground with any force with your head inside because the padding only crushes once, a bicycle helmet can survive many crashes.

We don't need it,no woodpeckers in NZ.

Plenty of Peckerwoods,,,but their mostly in the south island which is not really NZ anyway so it's still all good.

They are.

i dont know how you figure that out...the inside layer of a bicycle helmet is polystyrene just like a m cycle helment.The real difference is the outside layer of a cyle helmet is very very thin.its function is mostly cosmetic.

Bicycle helmets are treated the same as a motorcycle helmets. Any forceful impact and the helmet should be replaced. You think you wouldn't get hurt in a bicycle accident? Try hitting clipping your head on the ground or against a tree at 40kph....My bicycle helmets have saved me from getting major concussions a fair few times. Just because it doesn't have a motor doesn't mean its any less dangerous. People take bicycling for granted far too often and often get hurt alot more than if they would just wear a dam helmet.

Grab your push bike helmet and compare it to a motorcycle helmet, the push bike helmet doesn't really crush in a crash, I have cracked the shells on a couple of push bike helmets with no change to the actual shape of the helmet, they are designed for much lower energy impacts they do very little to stop concussion.
I have been hunting for the design rules to compare but it seems you have to spend about $60 just to see the document.

Don't wanna start a flame war but to say they do very little to stop a concussion would be rather ignorant. The fact you've cracked several kinda shows its absorbed the impact for you. :P

The whole point of a helmet is to prevent or lower the effects of a cranial impact. Both reduce the impact force by extending the time taken to slow down IE deceleration speed.

The thinner EPS foam could be a reason. Less material holding it together plus the designs having alot of ventilation holes compared to only a few on a motorcycle helmet.

I'd like to compare the design rules between cycle helmets and motorcycle helmets if anyone has a spare $120 (it's bullshit that this information is not freely available) the cycle helmets seem to spread the load and there would be a small amount of flex, but that's the point of the op, that cardboard would provide the ability to crush on impact, I've seen a few helmets broken clean apart also but never seen any real crushing of the internals, and every time I have cracked a shell I suffered a concussion and at relatively low speeds in comparison to a motorcycle helmet which is what makes me assume there are very different rules in play for m/c helmets

Have you looked there?

Try searching up the equivalent overseas accepted standards.

I've heard bicycle helmets are only meant to take impact up to 20kph...standard helmets. I've had full face helmets that were only slightly lighter and less beefy than motorcross helmets. Cost a bloody bomb but I believe its saved my head more than once.

That was the first place I tried, no useful information and I hunted for the Australian standards which are the ones I was talking about paying for, as for other countries they use their own standards and their tests could be far better or far worse than or own (borrowed from the Aussies).

The (hearsay) evidence I have found suggests that bicycle helmets are tested to withstand the impact with the ground only and perhaps a very small amount of abrasion resistance. Conversely I have seen independant tests that suggest a motorcycle helmet can withstand a point blank shot from a 12 gauge shotgun - including the face shield.

A truly new concept for helmets would be one of these http://www.6dhelmets.com/

Don't know if they plan on doing a road version.

Questions have been raised about shearing off the nodes, but I figure, you bin an EPS helmet after a good off anyway so...
