    6D Helmets ATR-2 Sector

    2 reviews

    The ATR-2 with advanced ODS is evolved to provide improved performance in both linear and angular acceleration mitigation, and is also easily rebuildable for a potentially longer service life. This improves rider safety and saves the consumer money. Optimized Shell Design: The 6D concept of 'Optimized Shell Design' does not define one element, but a system where multiple materials work together, in concert, to provide greater protection and energy management. The shell must have the structural integrity to prevent penetration, but it should not be overly stiff or rigid either. An overly stiff and rigid shell can seriously compromise the helmet's energy management potential. Multi-Impact Outer EPP (Expanded Polypropylene) Liner: 6D strategically positioned the multi-impact EPP outer liner against the helmet shell's inner surface. An exceptional energy absorption material, the EPP was specifically engineered with islands of EPP "Damping Towers" to assist in progressive loading of the ODS system during impacts. The multi-impact capability of the EPP is one of the key elements that allows the rebuilding of the ATR-2 after a moderate to severe impact. (Note: Helmet may be rebuilt provided the helmet's shell is not compromised from the impact event). Low-Friction Disks: Multiple smooth disks top the damping towers to reduce friction under loading thereby assisting in angular acceleration mitigation. Elastomeric Isolation Dampers: An array of Isolation Dampers connect the ODS carrier to the outer EPP liner and work in unison to isolate impact energy from the brain. The elastic properties of the dampers, combined with their unique shape provide a progressive spring rate that assists in managing low-threshold energy. The hour glass shape and elastic property also work to manage the three-dimensional displacement of the inner liner. Replaceable Inner EPS (Expanded Polystyrene) Liner: The inner EPS liner is the first layer of defense and a very important component of the new advanced ODS design. It is effectively a helmet within a helmet. It has its own in-molded PVC (Polyvinyl Chloride) shell that serves many functions. It nests into the ODS carrier, provides strength and integrity to the EPS, and serves as a slippery surface to aid in reducing angular acceleration forces. The EPS is of a softer density than the EPP and is secured into the helmet with four locking pins that mate to the ODS carrier. It is also captured by the Chin Bar EPP which provides additional security. ODS Carrier: The ODS carrier allowed the development of a modular helmet design that is easily rebuildable. The carrier also supports the isolation dampers and helps to manage the system materials during impact, compression, and shearing loads. ODS self-re-centers post impact. EPP Lined Chinbar: Thicker lower density EPP lined chinbar is more durable and provides more energy absorbing material for side impacts to the jaw area. It also includes a polyurethane over-molded sternum pad. New Safety Features: Two new safety elements have been engineered into the new ATR-2. The first, a structural "Brow Rib" provides incremental strength to the upper eyeport area providing additional integrity to the shell nearest the eyeport opening. Additionally, a strategically designed "Cervical Protection Zone" nests inside the lower rear base of the helmet. This area is designed to provide a more compliant crushable region in the event the helmet is pushed down and back into the neck and spine during an accident. Low-Threshold Energy: Low velocity impacts are far and away the most common type of off-road accidents. Medical research has provided alarming conclusions surrounding the causes, severity, and long-term effects of concussions. Even seemingly minor concussions may have much more serious long-term effects on the brain. No other helmet company cared about low-threshold energy transfer before 6D brought the issue to light in 2013. This is the most critical performance range of helmets and covers all impact velocities below the certification standard's requirements, for both linear and angular accelerations. 6D's Omni-Directional Suspension (ODS) starts working the instant any force is applied to the shell. Its suspended inner liner travels and shears under crash impact loading thereby reducing energy transfer to the brain. Angular Acceleration: Angular acceleration force is the primary cause of concussion. Angular acceleration (rotational force) is generated from oblique angle impacts to the helmet surface resulting in shearing, stretching, and tearing, of the soft tissues within the brain. The medical community has determined that angular acceleration is the primary cause of concussion, traumatic brain injury and worse. Laboratory testing at Wayne State University has proven that a helmeted head sustained the same degree of angular acceleration as the un-helmeted head when subjected to identical impacts. This is because the helmet is directly "coupled" to the wearer's head. One of the major benefit features of Omni-Directional Suspension (ODS) is that it effectively "uncouples" that relationship allowing the shell and outer liner to shear independently to the inner layer and the head-form; thereby scrubbing a high percentage of the angular acceleration force. Broad-Range Protection: The most compliant energy management solution available. The new ATR-2, with its advanced ODS system, elevates safety to the next level of energy management performance. Time-To-Peak (TTP): Time is critical in reducing energy transfer to the brain. 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 advanced ODS technology buys time. The Next Level: ATR-2 vs. ATR-1. The new ATR-2 with advanced ODS provides substantial improvements in performance over the current ATR-1 across the entire range of energy demands; low, mid, and high velocity accelerations for both linear and angular accelerations.
  2. Not long ago we were able to meet 6D Helmets' Co-Founder, Bob Weber during a media day at Cahuilla Creek MX park just outside Temecula, California hosted by InsideLine. We were able to discuss a little history, the details behind their revolutionary technology & what makes it different, advice on finding the right helmet, and what might be next for 6D all in Bob's own words. Co-Founder Bob Weber Explaining 6D's Patented ODS System ThumperTalk: How did 6D come about? What year? Bob Weber: I believed I had an idea worth developing to improve the capability of the helmet and better protect the human brain when subjected to oblique angle impacts in 2011. At that point, I contacted a good friend and engineer Robert Reisinger to help develop the technology. This process took us nearly 2 years. After prototype testing in an independent laboratory in Los Angeles, we were certain that we had a winning technology and could benefit the market with an improved helmet. It wasn’t so much a hole in the market we saw, but a massive development in how the helmet could be improved from an energy management and safety aspect. We sold our first helmets in 2013. ATR-2 'Circuit' from the 2019 Spring Collection ThumperTalk: Since the launch of 6D Helmets in 2013 there's been A LOT of helmet technology thrown into the market. So much so, it can be confusing for the consumer. What should a consumer look for (in technology) when purchasing a new helmet? Bob Weber: Today, helmets are much improved over the traditional designs of only a few years ago. So educating oneself on the various technologies out there should be the number one objective of the consumer. Riders, team managers, and parents should do their homework and learn about the different technologies available from the various brands out there, and how they differentiate from each other before they purchase. Head protection is about safety first, and should out-weigh any particular brand loyalty, cool graphic, or specific helmet design. ThumperTalk: Explain how Omni-Directional Suspension (ODS) works? And how is it so different to the standard style of helmets with EPS? Bob Weber: Simply put, the inner liner (much like an inner helmet) is uncoupled from the wearer’s head and can compress and shear within itself under impact conditions. This capability can dramatically reduce energy transfers to the brain from impacts at all velocities, and all impact angles. 6D’s ODS technology: Uncouples the outer surface of the helmet from the wearer’s head Dramatically improves low-threshold energy mitigation for both linear and angular accelerations Has less constraints based on the shape of the human head Is more tunable at the manufacturing level (defined by testing) Provides active suspension of the inner liner (6-Degrees of Freedom) Cutaway helmet showing the proprietary systems ThumperTalk: Since 6D came on the scene in 2013, it has started a kind of 'arms race' among helmet manufacturers for “new technology”. What are some certifications and testing standards that the consumer should be looking for when shopping for a quality helmet? Bob Weber: Actually, there are no standards currently established to help guide the consumer when exploring angular acceleration force and low-threshold energy compliance. This will take time and in general, the governing bodies are slow to respond. The FIM has instituted a new standard for closed course road racing in Europe that was adopted in June of this year. They also have an off-road standard in development, but currently there is no date established for homologation requirements. At 6D, we’ve been testing for these dynamics longer than anyone. We started in 2011 developing the ATR-1 and established a testing protocol that we conduct on top of the US DOT and European ECE standards. Our method establishes testing starting with low-velocity impacts, measuring both linear and angular acceleration performance, and then climbs at controlled velocities all the way up to the maximum certification velocities set by the regulating bodies. 6D helmets are certified to the US DOT, European ECE 22.05, ASTM F3103 and UK ACU standards. Also, worth mentioning here, 6D does not make different helmets for different markets because of standards. "We make one helmet, which exceeds the required standards in the US and all global markets, and sell that helmet everywhere"- Bob Weber ThumperTalk: How do you know when it is time to replace your helmet? What are some things to look for or best practices can you share? Bob Weber: Your helmet is a consumable device. It is designed to crush and yield when subject to impact force of some level of significance. After any moderate to severe crash you should inspect your helmet for damage, stress, or cracks in both the EPS material inside, and the shell surface. It is a good idea to have your dealer assist if you are unfamiliar with this process as damaged EPS is sometimes difficult to identify. Also, if you are competing on a regular basis, 2 to 4 times a month for 8 or 12 months out of the year, you are going to wear out a helmet and it should probably be replaced. Liners get played out, EPS compresses, and parts may be damaged by roost, crash, or poor handling and service. If there is none of that going on, your helmet may provide you 5 years or more of great service. ThumperTalk: What's next for 6D? Bob Weber: We are preparing to launch our new ATS-1R street helmet in July. We’ve put a lot of work into this helmet updating the technology and improving fit and features for the rider. The ‘1R is getting “Advanced ODS” similar to what is in the new ATR-2, but without the multi-impact capability. It’s also lighter, has improved shield fit and function, and better fit when putting on and off. Especially for people with larger heads where we were pretty tight before. We also have a couple of cycling helmets in development and pretty exciting project going with a multi-impact helmet for another market. Watch for a 6D and FXR collaboration this fall as well. These helmets should be available in August from FXR. **ThumperTalk would like to thank Bob & 6D Helmets for sitting down with us and talking helmets
