Abstract
Abstract A protective hat having shock absorptive and insulating properties includes a head-receiving member adapted to overlie and protect least the sides, top and rear of the head of a wearer. The head-receiving member includes a core of resilient shock absorbent polymeric foam material and a shell of textile fabric material wherein the shell is constructed and arranged to fully enclose and encapsulate the core so that the hat has a conventional appearance and surface texture. The core is provided with first and second core layers. The first core layer is formed of a substantially soft closed cell foam material having a thickness of about ⅛ to about ¾ inch. The second core layer is formed of a substantially hard closed foam material having a thickness of about ⅛ to about ⅜ inch. The core has spaced holes therethrough distributed over the surface of the core to facilitate ventilation of the concavity. The core also has a plurality of slits therethrough wherein the slits are disposed between the holes to facilitate conformity of the core to the shape of the head of the wearer and to further facilitate ventilation of the concavity.

Claim 1
Independent Claim
202 words
A protective hat having shock absorbing and insulating properties, comprising a head-receiving member adapted to overlie and protect at least the sides, top and rear of the head of a wearer, said head-receiving member comprising a core of resilient shock absorbent polymeric foam material and a shell of textile fabric material, said shell being so constructed and arranged as to fully enclose and encapsulate said core so that said hat has a conventional appearance and surface texture, said core comprising first and second core layers, said first core layer being formed of a closed cell foam material having a thickness of about ⅛ to about ¾ inch and said second core layer being formed of a closed cell foam material of higher compression resistance than said first core layer having a thickness of about ⅛ to about ⅜ inch, said core having a plurality of spaced holes therethrough distributed over the surface of said core to facilitate ventilation of said head-receiving member, and said core having a plurality of slits therethrough, said slits being disposed between said holes to facilitate conformity of said core to the shape of the head of a user and to further facilitate ventilation of said head-receiving member.
