Abstract: A safety helmet lining emitting far-infrared radiation is mounted inside a safety helmet and has an active layer and ceramic powder. The active layer is mounted inside a safety helmet. The ceramic powder is installed on the active layer and is made of material that is capable of inherently radiating far-infrared rays that can penetrate deeply into a human body and resonate with cells to activate cells and accelerate metabolism.

Abstract: A strong, lightweight, impact resistant helmet system protects the wearer from impact injury and minimizes bodily injury to other players brought into contact therewith during blocking and tackling events. Weight reduction is achieved by reinforcing inner and outer surfaces of the helmet shell with long length, high strength fibers. Orientation of the fibers is such that the fiber lengths are aligned generally in the direction of tension and compression forces imposed on the helmet surface during impact. This reinforcement geometry permits use of a thin helmet shell. Efficient impact absorption by the helmet shell is accomplished by limiting the bend curvature produced at the impact location. The bend curvature reduction increases the contact area between the helmet shell and a pliable padded inner helmet made from energy absorbing polymeric foam disposed within the helmet shell in contact with its inner surface.

Abstract: An ear covering is produced by sewing first and second cloth layers together along a first closed loop seam, and forming a hole inside the loop and extending through both layers; turning the sewn first and second layers inside out by passing one layer through the opening; then passing one of the layers through a passage in a flexible insert in the form of a distorted, truncated cone; placing a third cloth layer over one of the first and second layers and sewing the first second and third cloth layers along a second closed-loop seam, thereby enclosing the insert within a toroidal enclosure formed by portions of the first and second layers. Afterwards, the assembly is turned inside out to form a cup-shaped receptacle for receiving an external ear, with the second seam in the interior of the receptacle, and with the first seam within the toroidal enclosure.

Abstract: Integral complex buffing structure of safety helmet, including a casing, a lining body and a buffing body integrally sandwiched between the casing and the lining body. The casing is made of a hard plastic material. The lining body is connected on inner face of the casing and made of hardened foam material with high density.

Abstract: A helmet is formed with a rigid outer shell and three energy-absorbing layers made of two types of CONFOR™ ergonomic, open-celled polyurethane foams. The first layer adjacent the rigid outer shell is a CONFOR™ CF-40 yellow foam and the middle layer is a CF-47 green foam, which is of greater stiffness than the outer layer. The inner-most layer is also a CF-40 yellow foam and, therefore, identical to the outer energy-absorbing layer. The three layers are 0.5″ thick. The helmet body is secured to a user's head with straps, affording a helmet design capable of continuously absorbing energy from multiple impacts while retaining the property of returning completely to its original shape. The multiple layering of materials having different stiffnesses results in the reflection of propagating stress waves through the materials, ultimately absorbing larger amounts of energy than the same materials not layered with alternating stiffnesses could absorb.
