What's Different, and Why Is It Important?
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 de
