Patent attributes
An apparatus for use with a cap includes a rigid liner that is secured to an interior or exterior of the cap to provide impact protection over a portion of the forehead region, crown and temple area. An absorbent liner is preferably included if the cap does not include an interior liner. The absorbent liner absorbs perspiration from the brow of the wearer. An optional energy attenuating liner can also be included as an inner layer that is disposed adjacent to the rigid liner and intermediate the head of the wearer to more safely distribute kinetic energy. The energy attenuating liner can include a material that provides single-use only or multiple-use capability. The rigid liner and other components are either permanently attached to the cap or they may be detachably-attachable with respect to the cap or with respect to a remainder of the apparatus and replaced, as desired. Any preferred material may be used for any component part of the protective shield for a cap.
