ATR-1Y

THE STANDARD BY WHICH ALL OTHER YOUTH HELMETS ARE MEASURED

The ATR-1Y is the only premium helmet designed specifically for youth riders and is the ideal choice for MX and BMX competition.  Incorporating all of the amazing benifits of 6D’s revolutionary Omni-Directional Suspension technology, this helmet has no equal.

The ATR-1Y is designed with softer multi-density EPS materials, and softer isolation dampers that offer superior protection to the child’s still-developing brain and skull.  The helmet is smaller, lighter, and more compliant than the adult helmet and is certified to both DOT FMVSS 218 and ECE 2205 standards.

ONLY 6D HAS OMNI-DIRECTIONAL SUSPENSION 

6D’s revolutionary patented Omni-Directional Suspension (ODS) technology represents a fully active, in-helmet suspension and kinetic energy management system. Engineered to uncouple the helmet’s exterior shell from the inner EPS liner, the system effectively mitigates energy transfer to the head and brain of the rider during any given accident or impact event. The ODS system is comprised of 2 EPS liners separated by an array of elastomeric isolation dampers that allow the system to sheer and displace 3-dimensionally when subjected to impact.

Omni-Directional Suspension functions over a much broader range of energy demands, including LOW, MID and HIGH-Velocity impacts for both Angular and Linear accelerations when compared to other competing helmets, and helmet technologies.

There is simply no other helmet, or helmet technology that can provide the exceptional energy management benefits of Omni-Directional Suspension.

Elastomeric Isolation Damper

This damper is the heart and soul of 6D’s exclusive Omni-Directional Suspension technology. An array of dampers work in unison with the dual EPS liners to isolate impact energy from the brain. The elastic properties of the dampers, combined with their unique ‘hourglass’ shape provide a progressive spring rate that manages low and mid-velocity accelerations, while simultaneously allowing the inner EPS  liner to displace and shear in 3-dimensional space. This omni-directional displacement capability of the EPS liners provides ‘six degrees of freedom’, which became the inspiration for our company name; ‘6D Helmets.’

SUPERIOR ANGULAR ACCELERATION MITIGATION

ANGULAR ACCELERATION (ROTATIONAL) is generated from oblique angle impacts to the helmet’s surface.  The result of this type of impact, and subsequent energy transfer is shearing, tearing, compression, and rotation of the brain within the skull.  The medical community has determined that angular acceleration is the primary cause of concussion, mild-traumatic brain injury (MTBI), and traumatic brain injury (TBI).

Tests conducted by Dr. David C. Viano of  the Bioengineering Center at Wayne State University concluded that a helmeted head sustained the same degree of angular acceleration as the un-helmeted head when subjected to identical impacts.  So, if angular acceleration is a major cause of concussion (or worse), how is the brain protected by conventional helmet design? Unfortunately, in respect to angular acceleration energy, it is not.

By uncoupling the helmet’s inner liner assembly from the outer liner and shell, 6D’s revolutionary Omni-Directional Suspension (ODS) system effectively mitigates the transfer of angular acceleration to the head and brain of the rider during any impact event.

6D’s proprietary ODS technology dramatically reduces the transfer of angular acceleration to the head form compared to competitors.

SUPERIOR LOW-SPEED IMPACT PERFORMANCE

Recent medical research has provided alarming conclusions surrounding the causes, severity, and long-term effects of concussions and brain injury. We know that seemingly minor concussions may have much more serious long-term effects on the brain including the onset of CTE (Chronic Traumatic Encephalopathy), a progressive degenerative brain disease. Concussions can occur from impacts in the lower range of 60 G’s in adult males, and even less in women and children.

To meet the extreme test velocity requirements of Snell and ECE certification testing, most conventional helmets are engineered too stiff to effectively absorb energy from low and mid-velocity impacts. The vast majority of impacts in real-world accidents are what we qualify as LOW-THRESHOLD ENERGY impacts. These are impacts well below the pass/fail certification velocities of any given standard, but at or above the velocity required to sustain a concussion or brain injury. The isolation dampers within 6D’s exclusive Omni-Directional Suspension (ODS) system effectively mitigate low-threshold energy accelerations.   

In this critical area of energy management, the 6D ATR-1Y pays significant dividends when compared to conventional helmet designs. 6D’s proprietary ODS system starts working the instant any force is applied to the shell, making the helmet much more compliant and functional over the highest percentage of real world crash impacts. ODS achieves this benefit without compromise of its high-velocity impact performance as well.

SUPERIOR HIGH-SPEED IMPACT PERFORMANCE

Across the entire range of impact velocities the 6D ATR-1Y helmet with Omni-Directional Suspension (ODS) technology consistently outperforms the competition.  6D engineers meticulously evaluate the shell design, shell layup, damper array, damper durometer, and EPS densities to provide the best possible matrix of the materials for superior impact management performance. No other system or technology is more technically advanced or capable of reducing energy transfer to the brain.

TIME IS EVERYTHING

TIME-TO-PEAK (TTP) is the measurement of time (in milliseconds) it takes the energy of an impact to reach maximum (peak) G force.  Deceleration time is the single most beneficial component of reducing the severity and magnitude of any impact.  The more time, the less severe the energy transfer will become.  6D’s proprietary ODS technology buys time, in fact more than doubles the TTP in most impacts below 6m/s! The really cool news here is the significant reduction in energy transfer that comes simply with time.

SUPERIOR TEST PERFORMANCE

The exceptional test results represented on this website are the actual test data generated from hours of testing the 6D helmet against current model Snell, ECE and DOT certified helmets in a fully-independent, third party laboratory testing facility; Dynamic Research, located in Torrance, California is a recognized as a leader in helmet testing and evaluation and is a pioneer in measuring and evaluating Angular Acceleration.

This testing confirms that Omni-Directional Suspension (ODS) significantly reduces energy transfer to the head and brain during crash impact.
