A PATENT PENDING PRODUCT BY POC VENTURES IN PARTNERSHIP WITH THE CREATORS OF PROCAP
The helmet cover is a soft urethane material that can be easily attached to the outside of a helmet. The Guardian™ absorbs the majority of the impact produced by a helmet to helmet collision.
Concussions are the result of rapid changes in velocities between the brain and skull. A collision between the two disrupts the delicate neuronal layer of the brain relative to the magnitude of acceleration and the player’s physiology. For a designer, the message is simple: reduce the accelerations.
The Result: soft shell helmets.
(1)
Momentum = (mass x velocity) transfer is inversely proportional to the deflection of the impacted surface.
For example 1/8” deflection vs. 1/16” equals half the transfer.
(2)
Force magnitude is time governed. F=MxV/time of impact Given a player’s size and speed in any impact event,
the longer that impact time can be extended, the less the magnitude of the force.
The Guardian™ meets both these criteria by greater deflection and time extension during deflection. The automotive industry recognized this with soft bumpers and air bags. Additionally, NASCAR and other forms of racing have adopted soft walls.
GUARDIAN™ TECHNOLOGY
Penn State Biomechanics Lab quantified neck torque produced by glancing head forms- Hard on Hard = 40 NM and Soft on Soft = 38 NM. On narrow angle impacts (0-12 degrees) there was a similar non-distinguishable torque difference. However, soft shells produced a pronounced reduction of peak critical force, ranging from 8-33%, compared to the hard shells.
Tests conducted by Wayne State University Bioengineering labs in February measured Hard on Hard vs. Soft on Soft helmet impacts. In the side impacts the HIC was reduced from 360 to 289 and probability of concussions reduced from 80% to 55% respectively. In the rear impacts the reductions were 466 to 302 and 92% to 65% respectively.
Soft outer shell that dampens and redistributes the energy from a head-to-head contact. This greatly reduces the HIC to both players.
The soft outer shell eliminates the helmet from being used as a weapon. When there are hits to the hand, knee, leg, arm, etc… the force is greatly reduced by the soft outer cover versus a hard plastic shelled helmet.
We anticipate a significant drop in impact injuries with the widespread use of the Guardian™.
