HELMET WITH CHIN GUARD

摘要

Embodiments of the invention provide a protective device that may reduce head and facial injuries resulting from forces such as rotational and linear accelerations. According to an illustrative embodiment of the invention a helmet assembly is provided that includes a helmet shell to which a chin guard assembly is attached. The chin guard assembly is disposed and configured to protect the underside of the wearer's chin and jaw and counter rotational acceleration created by impact to the underside of the wearer's 30 chin or jaw. This supplements protection afforded by traditional helmets that are designed to protect against linear accelerations but fail to address rotational acceleration that can impart angular motion between the brain and brainstem, sufficient to cause concussions.
