Why Having RHEON™ In Your Helmet Is The Best Answer For Your Head

Next Generation Helmets

Things are changing in the world of helmets; concussion is a considerably bigger issue than it was even just 5 years ago. RHEON LABS is answering this new demand. Research shows that brain rotation is the key concern and cause of Mild Traumatic Brain Injury (MTBI) and risk of concussion when the head undergoes an impact. Existing helmet designs are not optimised to protect against this type of injury as the current standards do not require it.

RHEON LABS breaks with tradition. We develop solutions for real-world situations, rather than just meeting these existing, and in our view, outdated standards.

Having RHEON™ technology in your helmet is the best solution to protect your brain because it works for low speed, high speed and rotational forces, where most options tend only to deal with one of these.

RHEON™ technology: Expects the Unexpected

By its very nature, when you fall you don’t know where the impact is coming from. So having a system that absorbs energy across a wide dynamic range (i.e. at different speeds) and from both linear and rotational impacts, means the helmet (and you) are ready for anything.

Energy from these impacts needs to be transferred and absorbed. A RHEON™ liner is designed to absorb more energy than any of the alternatives:

  • HIGH SPEEDS IMPACTS Helmets enhanced by RHEON™ technology can pass both CE and DOT certifications with no weight penalty, showing that it can work across a range of high speed test conditions.
  • LOW SPEED IMPACTS Low speeds are ignored in testing since helmets don’t need to protect against low speed to meet the current standards. But research (Zhang et al., Journal of Biomedical Engineering, 2004, see graph) shows that you can have an 80% chance of Mild Traumatic Brain Injury (MTBI) following typical impacts at low speeds. A RHEON™ technology-enhanced helmet absorbs energy at these lower levels too, where competitors fall short.

  • ROTATIONAL IMPACTS The unique shapes of RHEON™ technology controls impact rotational energy too, since it decouples the helmet from the skull by introducing an active shear layer that absorbs energy in rotation. This shear movement counters rotational forces that can come from any direction. Other competitors rely on low friction layers within the liner to allow movement between the outer shell and the head. Whilst this can allow the helmet to rotate relative to the head in certain specific impacts (mainly head-on), it is not optimised for energy absorption. More effectively, RHEON™ technology isolates the head from rotational movement in the helmet, but does so actively over a range of speeds (and from any direction!), by absorbing and controlling the impact energy.
  • COMFORT & FIT RHEON™ material is soft and flexible under normal conditions, and its geometries make it lightweight and improve air-circulation too. So whether as a soft internal shell, a separate (fully-washable) liner or individual helmet inserts, it enhances comfort and improves the fit of your helmet. Helmets that fit better perform better.

And because in real-life scenarios you may have a big wipeout with multiple impacts in close succession, it is reassuring to know that the RHEON™ technology is not compromised or degraded after the first impact. RHEON™ technology is ready when you need it to be.
