Helmet impact zones

Plaka · 03-13-2013, 09:45 AM

I notice people mounting cameras and communicators on the outside of their helmets.

I'm thinking of mounting some odd devices on the outside of my helmet. They are pretty fragile and will shatter if they get hit, which is no big deal. But I don't want to create stress risers that will make the helmet less protective in a crash. The helmet is a Schuberth (like the BMW system 1).

I'm thinking of mounting the black box at the nape of the neck and 4) 1/2" high x 1/2" D. bumps to the chin piece.

The bumps are LED strobes and the box is the controller for them.

Thots?

Have a look at this graphic, then add up the percentages. http://motocorsa.com/post/why-you-sh...ll-face-helmet It might help you decide where to mount things.

That is extremely helpful. Thank You!

I would worry less about the components reducing the helmet's ability to protect against impact and maybe about the components contributing to additional rotational energy.

Either way, the cheap plastic add-ons will help to dissipate energy if they break and shatter.

as a FYI, SHARP reports relative helmet performance for a tested models for the forehead, top, side and back. Most helmets do very poorly in the side impacts...
