third embodiment
[0085]FIG. 14 illustrates the internal liner layer 32 wherein the liner is provided with a geodesic dome shape having triangular shaped cutouts. Stated another way, in this configuration, the lines of the thermoplastic are formed into triangles which meet at the vertices.
fourth embodiment
[0086]FIG. 15 illustrates the internal liner layer 32 wherein the liner is non-continuous and is provided with a honeycomb, wherein the liner defined hexagonal shapes. Still other examples of inner liner configurations will be recognized by those skilled in the art, including combinations of the described patterns.

A multilayer shell for use in the construction of protective headgear, the shell including an outer layer, an inner layer, a middle layer disposed between the outer and inner layer which resiliently compresses in response to an impact to the outer layer, and an internal liner disposed inwardly of the inner layer. The middle layer includes a plurality of compressible members, which resiliently compress to absorb the energy of a direct impact to the outer layer and resiliently shear with respect to the inner layer in response to a tangential impact to the outer layer. The inner layer includes an open configuration, which reduces the weight of the shell, provides for greater heat ventilation from the head of the user, and permits for visualization of the compressible elements. The internal liner is formed from contourable materials which enhance user fit and comfort and reduce the weight of the protective headgear without compromising user safety.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part application claiming priority to co-pending U.S. patent application Ser. No. 11 / 059,427, filed Feb. 16, 2005, titled “Multi-Layer Air-Cushion Shell With Energy-Absorbing Layer For Use in the Construction of Protective Headgear.” The entirety of this co-pending patent application is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to protective headgear. More specifically, the invention relates to a layered construction of protective headgear having an inner liner having an open configuration which reduces the weight of the liner and allows for greater ventilation from the head and an internal liner formed of head contouring materials that improve the fit and comfort of the headgear further reduce the risk of and protect an individual' s head from injury.BACKGROUND INFORMATION[0004]Concussions, also called mild...
