1. Field of the Invention
The present invention relates generally to helmets used as protective gear.
2. Description of Related Art
Helmets are well known in the art to be securely fashioned to a head and provide padding in an attempt to absorb impact. Most helmets are designed to prevent skull injury and most testing systems test for this ability. Recently the concept of brain injury separate from skull injury has come to light and helmets are not typically designed to prevent such injuries well. Current helmets may dampen high crushing forces, but they do nothing to reduce against rotational forces that can damage the brain and the upper spine.
A need exists, therefore, for a helmet that protects the brain and upper spine as well as the skull.

BRIEF SUMMARY OF THE INVENTIONThe problems presented in typical helmets are solved by providing a helmet with two shells connected by a plurality of discrete elastomeric elements.
Other objects, features, and advantages of the present invention will become apparent with reference to the drawings and detailed description that follow.
All references cited herein are incorporated by reference to the maximum extent allowable by law. To the extent a reference may not be fully incorporated herein, it is incorporated by reference for background purposes and indicative of the knowledge of one of ordinary skill in the art.
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific preferred embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is understood that other embodiments may be utilized and that logical mechanical and electrical changes may be made without departing from the spirit or scope of the invention. To avoid detail not necessary to enable those skilled in the art to practice the invention, the description may omit certain information known to those skilled in the art. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
Elastomeric elements 16 are comprised of a body 30, shanks 32 extending from the body 30, and heads 34 attached to shanks 32. Body 30 sits between outer shell 12 and inner shell 14, while shanks 32 extend through boreholes 26 in inner shell 14 and outer shell 12. Heads 34 are shaped to fit recesses 28 in the outer surface 36 of outer shell 12 and inner surface 38 of inner shell 14. Elements 16 are made of elastomeric materials such as urethane, silicone, or other material with similar elastomeric properties, including mixtures of materials or combinations of materials within the same elastomeric element. The elements 16 are placed in aligning boreholes 26 to secure inner shell 14 within outer shell 12 and provide an elastic connection between inner shell 14 and outer shell 12 that allows outer shell 12 to rotate relative to inner shell 14 as well as absorb shocks applied to outer shell 12 so that they are not fully transmitted to inner shell 14.
As shown on one element 16 in both
Other methods for placement may be used for elastomeric elements 16, but placement strands 40 are one placement method that can be done by hand.
Even thought he embodiment shown in this application is in a sports helmet with several optional features the basic concept is easily applicable to military helmets, construction helmets, safety helmets, and other helmet applications. Also, the basic concept may be used in helmets with less of the optional features, such as a football helmet with no visor.
It should be apparent from the foregoing that an invention having significant advantages has been provided. While the invention is shown in only a few of its forms, it is not just limited but is susceptible to various changes and modifications without departing from the spirit thereof.
