ABSTRACT:
The protective helmet includes a rigid outer shell where the shell includes an undulating cross-sectional profile. A layer of impact-energy-absorbing material is positioned adjacent to the shell. The undulating profile of the shell can be any type of load spreading undulating profile, such as that of a sinusoidal or triangular wave configuration. The undulating load-spreading profile can be on the inner surface of the shell, on the outer surface of the shell or the entire cross-section of the shell may be undulating. The unique undulating profile makes the shell more rigid and spreads the impact load across the surface of the shell to thereby spread the deformation of the padding layer to prevent the shell from bottoming out of the impact-energy-absorbing material during an impact. As a result, a safer and more effective protective helmet is provided.
