Publication number: 20140013492Abstract: Embodiments provide protective helmets configured to protect the head from linear and rotational acceleration in an impact. In various embodiments, the helmets may include an outer layer, an inner layer, and at least one intermediate layer coupled to the outer and inner layers by alternate fixation sites, thereby providing a suspension between the outer and inner layers. In various embodiments, the intermediate layer may be made from a honeycomb material, such as an aluminum honeycomb. In use, in-plane deformation of the honeycomb may allow for translation of the outer layer in a substantially tangential direction relative to the inner layer, thereby mitigating rotational acceleration imparted by the tangential impact component.Type: ApplicationFiled: March 14, 2013Publication date: January 16, 2014Applicant: Apex Biomedical Company LLCInventors: Michael Bottlang, Steven Madey, Nathan Dau, Kirk Hansen, Ashton Wackym
