BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to a soft shell padded helmet, and more particularly to a three-ply soft shell padded helmet.
Description of the Related Art
Head trauma resulting from sports and other activities is a common occurrence. Generally, head trauma occurs when an object impacts the head, thereby transferring energy to the head. The most common head trauma resulting from sports is a concussion, which occurs when the brain bangs inside the skull and is bruised. To reduce the incidence of concussion, it is common practice to wear a protective helmet. Protective helmets are ostensibly designed to deflect and absorb energy transmitted by impact to the helmet, thereby diminishing the risk of head and brain injury resulting from the impact.
Protective athletic helmets have been worn for almost a century, and have evolved from sewn leather, to helmets having molded plastic outer shells with suspension webbing or other head fitting structures such as foam pads, air bladders, or padded molding on their interior. Despite the evolution of the protective helmets, the reported rate of concussions has been increasing amongst student and professional athletes in many sports. While some experts have attributed this increase to better reporting and diagnosis, other experts have attributed the increase to increased forces generated as competitive athletes continue to increase in size (mass) and increase their ability to accelerate.
When an individual participates in contact sports activities such as football, lacrosse, hockey, and the like, it is common that parts of the individual's body are subject to impact and other physical contact. Various attempts have been made to provide padding as a means of protecting the individual during such activities. Conventional protective equipment can include, as nonlimiting examples, helmets, shoulder pads, thigh pads, and shin pads. Typical protective equipment may include reinforced-sponge type padding, such as a rubber sponge layer laminated with a stiff plastic layer.
It is an object of the invention to provide an improved helmet.
SUMMARY
The invention provides various embodiments of a soft shell padded helmet comprising a plurality of pads, wherein each pad is configured in a multi-layer configuration. The different embodiments comprise elements to provide a padded helmet that is light-weight and adapted to reduce the risk of head trauma due to the multi-layered padded configuration.
In one embodiment, as broadly described herein, a padded helmet comprising a top portion and a side portion, wherein the top portion is coupled to the side portion. The top and side portions each can comprise at least one pad and at least one opening. The at least one pad comprising a multi-layer configuration. The helmet can also comprise a coupling means coupled to the side portion to secure the padded helmet.
These and other aspects and advantages of the invention will become apparent from the following detailed description and the accompanying drawings which illustrate by way of example the features of the invention.

With reference to FIGS. 1a-1d, an exemplary padded helmet 10 is shown. The padded helmet 10 comprises a top portion 12 and a side portion 14, wherein the top portion 12 and side portion 14 are coupled. The top portion 12 can comprise a plurality of pads 16, a plurality of holes 18, and a shell 13 covering the pads and the exterior and interior surfaces of the top portion 12. The top portion 12 is arranged to cover the top of a user's head. The plurality of holes 18 allow for ventilation such that when a user is wearing the padded helmet 10, heat from the user's head can be easily dissipated.
The side portion 14 can comprise a plurality of pads 16 and shell 13, similarly as in the top portion 12. The side portion 14 can further comprise at least one earhole 20. The side portion 14 is arranged to cover the sides and rear portion of a user's head such that the at least one earhole 20 is aligned with the ears of the user. The at least one earhole 20 allows the user to hear while using the padded helmet 10 and can also provide ventilation to assist in dissipating heat from a user's head. Ventilation provides ease of use and comfort for the user, especially during long periods of use of the padded helmet 10.
The side portion 14 of the padded helmet 10 extends around the user's head and covers the sides, rear and part of the user's forehead. The side portion 14 is coupled to the top portion 12 in order to form the shape of the padded helmet 10. A seam 22 extends along the area between the top portion 12 and the side portion 14 in order to couple the top and side portions 12, 14.
The side portion 14 can further comprise a strap 24 to fasten the padded helmet 10 to the user's head, a plurality of pads 16 to provide protection to the sides and rear of the head, and an adjustment section 26. The adjustment section 26 comprises an opening 28, a plurality of holes 30 and a lace 32. The lace 32 is received within each of the plurality of holes 30 to adjust the size of the padded helmet 10 to accommodate different sized heads and/or to increase/decrease how tight the padded helmet 10 is on the user's head. The opening 28 runs along the back part of the padded helmet 10 between the top and side portion 12, 14 which allows the size of the padded helmet 10 to be adjusted. The strap 24 can comprise a hook and loop system in order to fasten the padded helmet to the user's head. However, the strap 24 can be arranged in many different ways and is not intended to be limited to a hook and loop system. In other embodiments, the strap 24 can be arranged as a belt, clasp, buttons, and/or any other known attachment device known in the art.
In one embodiment of the invention, the pads 16 are soft, shock-absorbent and assist in preventing head trauma to a user when wearing the padded helmet 10. The pads 16 can be arranged in many different configurations and many different shapes. In one embodiment, the pads 16 are shaped differently from one another. For example, the pads 16 on the top portion 12 are smaller in comparison to the pads 16 on the side portion 14, which allows the top portion 12 of the padded helmet 10 to be bent in the shape of the user's head. This allows the top portion 12 of the padded helmet 10 to closely conform and/or resemble the shape of the user's head and thereby provide maximum protection. The pads 16 on the side portion 14 of the padded helmet 10 are bigger, in size/shape, than the pads 16 on the top portion 12 because the curvature of the side of user's head is typically less curved than the curvature of the top of the user's head. The pads 16 are pliable and the pads 16 of the side portion 14 can substantially conform to the shape of the side of a user's head.
Each of the pads 16 can be arranged in a multi-layer configuration and are adapted to minimize direct impact and absorb more of a direct force than conventional soft padded helmets that are arranged as a single layer. In one embodiment, the pads 16 comprise a three-ply configuration of padding material comprising three different layers of padding material that are sandwiched together. The three layers of padding material are heat treated in order to couple each of the layers of padding material together to form the three-ply configured pads 16.
In one embodiment, each layer of padding material within the three-ply pads can have a different density and/or thickness. For example, a three-ply pad 16 can comprise a first, second, and third layers 40, 42, 44. The first layer can have a thickness of 15 mm, the second layer having a thickness of 35 mm, and the third layer having a thickness of 15 mm. The second layer 42 can be arranged to have a higher density than the first and third layers 40, 44, such that the second layer 42 is interposed between softer and/or less dense first and second layers 40, 44. This configuration offers maximum comfort and improved protection over conventional soft, single-layer padded helmets, while yet still being comfortable to the user. The invention is not intended to be limited to the thicknesses disclosed herein. The dimensions presented herein is an example of an embodiment of the invention, and the pads 16 can be arranged to have different dimensions. In other embodiments, the first, second and third layers 40, 42, 44 can have dimensions that are higher or lower than the sample dimensions disclosed herein.
FIG. 2 discloses a cross-sectional view of one of the three-ply pads 16 used in the upper and side portions 12, 14 of the padded helmet 10, according to an embodiment of the invention. FIG. 2 shows the three-ply configuration of the pads wherein the second layer 42 made of denser material is surrounded by the softer and less dense first and third layers 40, 44. In the embodiment of FIG. 2, the pads 16 comprise three layers that are made of ethylene-vinyl acetate (EVA) that are heat treated in order to couple the layers 40, 42, 44 together, wherein the second layer is more dense than the first and second layers. However, the invention is not intended to be limited to three layers of EVA. The pads 16 of the padded helmet can be arranged in many different ways, such as but not limited to, having more than three-ply configuration, the pads having the same thickness and/or density, made of other materials in addition to EVA and/or a combination thereof. The padded helmet 10 can have a shell 13 formed of breathable, elastic, durable material on the interior and the exterior of the helmet, which helps make the helmet light-weight and breathable. The helmet can be used during sports and other activities or for people with balance problems, head/skull injuries, seizure disorders, and/or the like.
Although the invention has been described in detail with reference to certain configurations thereof, other versions are possible. In the embodiment of FIGS. 1a-d and 2, the shell can be formed of a natural material, synthetic material, and/or a combination thereof, such as but not limited to cotton, spandex, LycraTM, and/or any other material known in the art that is light-weight, elastic and breathable. Therefore, the spirit and scope of the invention should not be limited to the versions described herein.
