Abstract: An improved padding system for a helmet and process for designing the padding system are described. In one example, a helmet for an individual can include an outer shell having an inner surface. The helmet can further include a padding system coupled to the inner surface. The padding system can include pad clusters that are respectively positioned at different locations on the inner surface. Each of the pad clusters can include discrete pads that are individually coupled to the inner surface in a defined arrangement. In one example, the defined arrangement can be a certain arrangement that allows the discrete pads to collectively provide a desired system stiffness for the padding system. The desired system stiffness in this example can be a certain system stiffness that can reduce at least one of peak linear or peak rotational accelerations to the head of the individual during an impact.

Abstract: Various embodiments relating to methods for evaluating injury mitigation performance of helmets that are used for sports (e.g., whitewater kayaking and rafting) are described. In one embodiment, a method for evaluating injury mitigation performance of a helmet includes applying a first impact configuration to a first helmet and applying a second impact configuration to a second helmet of the same model as the first helmet. The method further includes generating acceleration data based on impacts that occur as part of the first impact configuration and the second impact configuration. The method further includes determining concussion risk values based on the generated acceleration data. The method also includes determining a concussion risk metric based on the concussion risk values and exposure values.
