DETAILED DESCRIPTION

[0022] The Figures provided herein generally depicts a helmet having a semi-soft outer shell adjacent to a web and spaced apart from a tight fitting inner shell. The semi-soft outer shell is made from a high absorbent material. The web is made of a plurality of strips that compress on impact and become more rigid the more they are compressed. An air space separates the web from the inner shell. The inner shell is also made of the soft and highly absorbent material that the outer shell is made from. The inner shell is configured to be tightly fitting.

[0023] Referring now to FIG. 2, a helmet 100 includes a semi-soft outer shell 102 positioned adjacent to a web 106. The semi-soft outer shell 102 and the web 106 is spaced directly adjacent thereto. In other embodiments, an air gap is positioned between the outer shell 102 and the web 106. In this alternative embodiment, the outer shell 102 and the web are positioned directly adjacent to each other.

[0024] An inner shell 112 is configured to tightly fit against the user's cranium 110. The inner shell 112 may include a plurality of blisters 114 to further aid in shock absorption. The blisters 114 may also be referred to as protrusions. The blusters extend 114 extend into the air gap 108. The large air gap 108 is positioned between the inner shell 112 and web 106.

[0025] The helmet 100 of the present embodiment varies dramatically from traditional helmets in that the outer shell or layer of the helmet is generally less hard than tradition helmets, being semi-soft or partially rigid. Conversely, traditional helmets have a very hard outer shell or layer. The semi-soft outer shell or layer of the present helmet aids in softening impact to the user's cranium.

[0026] In the present embodiment, the inner shell 112 and the web 106 are spaced apart a predetermined distance T.sub.1 (the air gap). This thickness T.sub.1, in the present embodiment, ranges between 0.25 inches to 2 inches (6.2 millimeters to 50.8 millimeters). This air gap 108 having a predetermined thickness T.sub.1 is utilized and incorporated to further assist in the shock absorption to the cranium 110. The air gap allows for space of movement of the cranium (skull) to move allowing the velocity of the cranium to lessen as the cranium moves towards the layers of the web 106 and the outer shell 102.

[0027] A predetermined thickness T.sub.2 is the thickness of the semi-soft outer shell 102. The semi-soft outer shell 102 is comprised of a material having a high durometer of approximately 50-60. The material comprised of the semi-soft outer shell 102 is resilient. The semi-soft outer shell 102 having the predetermined thickness T.sub.2 acts as the initial shock absorbing layer to the helmet 100. In the present embodiment, the predetermined thickness T.sub.2 ranges between 1 millimeter to 10 millimeters, but may vary depending on the type of material used for the semi-soft outer shell 102.

[0028] The web 106 includes a predetermined thickness T.sub.3. While the overall web 106, as show in the subsequent figures, includes a plurality of apertures, the thickness of the physical portions of the web 106 have a predetermined thickness T.sub.3 where T.sub.3 ranges between 1 millimeter and 5 millimeters. As illustrated in FIGS. 5 through 9, the web 106 may have various configurations and arrangements.

[0029] The predetermined overall thickness T.sub.4 includes the entire thickness of the outer shell, the web, the air gap and the inner shell. The overall thickness T.sub.4 ranges between 8.2 millimeters to 65.8 millimeters.

[0030] FIGS. 5 and 6 illustrate a first embodiment of the web 106. In this embodiment, the web 106 includes a plurality of similar dimensioned strips 188. In the embodiment as illustrated in FIG. 4, the strips 118 are interconnected and molded together to form a one piece web material and portion, such as illustrated at 106. FIG. 3 illustrates a cross sectional view of the strips 118 when the web is installed into the helmet configuration. The spacing of the strips 118 may vary depending on testing and the needs of the user. Furthermore, the materials of the strips 118 may also vary depending on the required shock absorption, cost and weight.

[0031] Similarly, FIGS. 7 and 8 illustrate an alternative embodiment of a web 206. In this embodiment, the web 206 includes a plurality of strips 218 crossing upon one another in a rectangular configuration. Such as in the prior embodiment, the strips 218 may vary and have different spacing with respect to each other. The material of the strips 218 may also vary depending on the requirements of the user and shock absorption requirements. FIG. 5 illustrates a cross sectional view of the web 206 having the strips 218. In this present alternative embodiment, the strips 218 have a generally triangular cross section which further facilitates shock absorption of the overall helmet 100.

[0032] Similarly, FIG. 9 illustrates yet another alternative embodiment of a web 306. In this embodiment, the web 306 includes a plurality of strips 318 crossing upon one another in a diagonal configuration. Such as in the prior embodiment, the strips 318 may vary and have different spacing with respect to each other. The material of the strips 318 may also vary depending on the requirements of the user and shock absorption requirements. In this present alternative embodiment, the strips 318 have a generally triangular cross section which further facilitates shock absorption of the overall helmet 100.

[0033] FIG. 3 generally illustrates the helmet 100 from a top view having a partial cross sectional view illustrating the cranium 110. FIG. 2 illustrates a top view where the face mask 120 is visible. The web 106 is illustrated in yet another alternative embodiment where webbing is only used in a portion of the helmet.

[0034] In some embodiments, the inner shell 112 made be customized to fit the users head to ensure a tighter and better fit. The inner shell 112 may also have some stretch and give to allow the user to have a more snug fit on the cranium 110.

[0035] In an assembled position, the various layers of the helmet 100 including the semi-soft outer layer 102, the web 106, and the inner shell 112 are connected to a base portion (not shown) to secure each layer and element together.

[0036] The soft configuration of the outer shell 102 decreases the overall weight of the helmet 100, increases comfort to the user, and improves shock absorption upon initial impact. The incorporation of the semi-soft outer layer 102 with the webbing 106 and the inner shell 112 allow for a lighter and more comfortable helmet to be worn by the user.

[0037] In some embodiments, the helmet of the present specification may be of a modular configuration. In his situation, the various layers may be replaceable and substitutable with other layers of portions of the helmet. The ability to provide for a modular helmet offers several advantages in that broken parts of layers can be replaced. This may extend the life of the helmet as worn by the user. The modularity is also advantageous in that the helmet may be able to be customized as prescribed by the user. This may include providing softer materials, more resilient materials or materials or layers having different sizing so as to better fit the users head.

[0038] The materials used to make the semi-soft outer layer, the web and the inner shell may vary depending on the needs of the specific helmet and based on the needs of the user. In some embodiment, the semi-soft outer shell is a form of a plastic, plastic or similar material having similar properties as plastic such as various polymers, plastic-like materials, polymer-like materials, rubber or any other suitable material. In some embodiments, the web is a form of a plastic, plastic or similar material having similar properties as plastic such as various polymers, plastic-like materials, polymer-like materials, rubber or any other suitable material. The soft inner shell, in most embodiments, is a soft cloth like material such as Sorbothane® or having material and energy absorption characteristics similar to Sorbothane®. The inner shell may also be (or have an additional layer) any suitable cloth or cloth like material having elastic properties. The elastic properties ensure a tight and secure fit for the user. Other suitable materials for any of the layers may also be provided so long as they exhibit the resiliency, adsorption properties and elasticity properties required for the helmet and as required by the user or the sport or activity that a theoretical user is participating in.

[0039] To promote modularity, the layers are removably connected together by means of a fastener or their clip so as to connect the layers of the helmet together. This clip or fastener is provided at the outer edges of the layers of the helmet as proved above.
