| IN A NUTSHELL |
|
In the world of cycling safety, helmet technology is advancing rapidly to address the risks associated with high-speed impacts. Traditional helmets, primarily composed of foam, are designed to cushion the head from direct blows. However, these helmets often fall short when it comes to rotational impacts, which can lead to serious brain injuries. A new technology called the Release Layer System (RLS) aims to fill this gap. Developed by a British startup, RLS offers enhanced protection against concussions by utilizing ball bearings and detachable panels, which work together to dissipate rotational energy during an impact. This innovation is set to make its debut with the Canyon Deflectr RLS helmet this autumn.
Understanding the Mechanics of Rotational Injuries
When a cyclist falls, the head often hits the ground at an angle rather than a direct, straight impact. This angular collision causes the helmet to catch briefly on the road surface, creating a rotational force. The human brain, which floats within the skull, does not move in perfect synchrony with the head. As a result, this delay in movement can lead to what is known as a rotational injury. Such injuries are particularly dangerous because they can shear nerves and blood vessels, potentially causing severe brain damage or even death.
To address these rotational injuries, the MIPS (Multi-directional Impact Protection System) was developed. It involves a flexible inner lining that shifts slightly with the head’s movement, reducing the rotational force transmitted to the brain. However, the RLS technology takes a different approach by focusing on the helmet’s exterior. Rather than relying on internal adjustments, RLS utilizes an external layer designed to absorb and mitigate the rotational forces during an impact.
Introducing the Release Layer System (RLS)
The brainchild of Jamie Cook, CEO of RLS and founder of the 3D-printed helmet company Hexr, the Release Layer System is a groundbreaking innovation in helmet safety. Cook’s inspiration came from observing the outer shell of a 3D-printed helmet detaching during a sudden impact. Building on this observation, RLS was designed to enhance helmet safety by incorporating a mechanism that actively responds to rotational impacts.
The RLS helmet is equipped with polycarbonate bearings covered by thin panels. These panels are secured with a special adhesive that remains intact during everyday use. However, in the event of a rotational impact, the adhesive releases, allowing the panels to move across the bearings and detach. This process effectively dissipates the rotational energy, reducing the risk of brain injury.
The RLS technology reduces peak rotational velocity by an average of 57% to 66%, which corresponds to a 68% to 86% reduction in the probability of brain injury.
Performance and Testing
The effectiveness of the RLS technology has been demonstrated through rigorous testing. Conducted at the University of Strasbourg, these tests compared the performance of RLS-equipped helmets to traditional designs. The results were impressive, showing a significant reduction in peak rotational velocity across various impact locations. This reduction translates to a lower likelihood of brain injury during a cycling accident.
Thanks to these positive outcomes, the Canyon Deflectr RLS helmet now holds the top spot on Virginia Tech’s esteemed helmet ratings chart. It surpasses even the MIPS-equipped helmets, highlighting the potential of RLS to set a new standard in cycling safety. As the technology becomes more widely adopted, it is expected to be incorporated into other helmet models, further enhancing safety for cyclists worldwide.
The Future of Cycling Safety
As cycling continues to grow in popularity, the demand for improved safety measures remains high. Innovations like the Release Layer System are crucial in addressing the limitations of traditional helmet designs. By focusing on rotational impact protection, RLS represents a significant advancement in the field, offering cyclists increased security and peace of mind.
Looking ahead, the integration of RLS technology into various helmet models could revolutionize cycling safety standards. As more cyclists become aware of the risks associated with rotational injuries, the adoption of such technology is likely to increase. The success of the Canyon Deflectr RLS helmet serves as a testament to the potential impact of these innovations on reducing cycling-related injuries and fatalities.
The introduction of the Release Layer System marks a pivotal moment in the evolution of helmet technology. As this innovation becomes more widespread, it raises important questions about the future of cycling safety. How will other manufacturers respond to this advancement, and what further innovations might we see in the quest to protect cyclists from head injuries?
