DETAILED DESCRIPTION

(15) While this disclosure includes embodiments in many different forms, they are shown in the drawings and will herein be described in detailed particular embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosed methods and systems, and is not intended to limit the broad aspect of the disclosed concepts to the embodiments illustrated.

(16) Protective head gear and helmets have been used in a wide variety of applications and across a number of industries including recreation, sports, athletics, construction, mining, military defense, and others, to prevent damage to users' heads and brains. Damage and injury to a user can be prevented or reduced by preventing hard objects, sharp objects, or both, from directly contacting the user's head, and also by absorbing, distributing, or otherwise managing energy of an impact between the object and the user's head. Straps or webbing are typically used to allow a user to releasably wear the helmet, and to ensure the helmet remains on the user's head during an impact.

(17) Protective headgear or helmets can be used for a snow skier, cyclist, football player, hockey player, baseball player, lacrosse player, polo player, climber, auto racer, motorcycle rider, motocross racer, snowboarder or other snow or water athlete, sky diver, or any other athlete, recreational or professional, in a sport. Other non-athlete users such as workers involved in industry, including without limitation construction workers or other workers or persons in dangerous work environments can also benefit from the protective headgear described herein, as well as the system and method for providing the protective head gear.

(18) Helmets function to provide protection while minimizing interference with an activity. The shape of a helmet may be adapted to provide both protection and comfort (e.g. allowing ventilation and variation of sizes). Some helmets are made of two or more bodies of energy-absorbing material formed in shapes that would be difficult, if not impossible, to achieve in a single molded piece.

(19) Various implementations and embodiments of protective helmets according to this disclosure comprise a protective shell. The protective shell may be formed of an energy absorbing material such as expanded polystyrene (EPS), expanded polyurethane (EPU), expanded polyolefin (EPO), expanded polypropylene (EPP), or other suitable material. The energy absorbing material can be used as part of a hard-shell helmet such as skate bucket helmets, motorcycle helmets, snow sport helmets, football helmets, batting helmets, catcher's helmets, or hockey helmets, and include an additional outer protective shell disposed outside, or over, the protective shell. In hard shell applications, the energy absorbing material may comprise one or more layers of EPP and provide more flexibility. Alternatively, the energy absorbing material may be part of an in-molded helmet such as a bicycle helmet. An outer shell, such as a layer of stamped polyethylene terephthalate or a polycarbonate shell, may be included on an outer surface of the protective shell of the helmet and be bonded directly to the energy management liner.

(20) Contemplated as part of this disclosure is a helmet having shoulder pads as well as a method of assembling a helmet.

(21) FIGS. 1A-2B show different views of a helmet 100 comprising a helmet body 102. A helmet may further comprise a fit system within the helmet, which may be as simple as a chin strap or may be more complex and include adjustment pieces within the helmet body. The fit system couples to the helmet body 102 and is accessible to the wearer from inside and/or outside the helmet body to fit and adjust the helmet to the wearer's head.

(22) The helmet body comprises an outer shell 104 and an energy management liner 200 disposed adjacent the inner surface 118 of the outer shell 104 (FIGS. 2A and 2B). The majority of the energy management liner 200 is disposed inside the outer shell 104. The energy management liner 200 provides impact protection for the wearer and is not just a comfort liner.

(23) The outer shell may comprise any materials known in the art of helmets, such as, but not limited to, one or more of ethylene vinyl acetate (EVA), Acrylonitrile butadiene styrene (ABS), polyvinylchloride (PVC), polycarbonate (PC), polyethylene terephthalate (PET), or other plastic, as well as resin, fiber, fiberglass, carbon fiber, textile, or other suitable material, whether cast, formed, molded, stamped, in-molded, injection molded, vacuum formed, or formed by another suitable process.

(24) The energy management material may comprise any materials known in the art of helmets for use as energy management, such as, but not limited to, one or more of plastic, polymer, foam, or other suitable energy absorbing material that can flexibly deform with a hard outer shell to absorb energy and to contribute to energy management without breaking. The energy absorbing layer can be one or more layers of EPP, EPS or EVA, which can be used as an energy absorbing and energy attenuating material that is flexible and is able to withstand multiple impacts without being crushed or cracking. In other instances, EPP foam, EPS, EPU, or EPO can be used or in-molded for absorbing energy from an impact.

(25) The outer shell 104 comprises an inner surface 118, an outer surface 120, and an outer shell lower edge or lower edge line of the helmet outer shell 106. The outer shell lower edge 106 is positioned along the sides 112 of the helmet outer shell 104. The outer shell 104 further comprises at least two shoulder pad recesses 124 at its bottom (FIG. 1B), recessed into the outer shell lower edge 106. The side 112 of the outer shell 104 also forms a nominal lower edge line 108 (FIG. 3), which is a continuous smooth line starting from the lower front edge 114 of the outer shell 104 to the lower rear edge 116 of the outer shell 104. The outer shell lower edge 106 indents upward relative to the nominal lower edge line 108 to form the shoulder pad recesses 124.

(26) The energy management liner 200 comprises at least two or more shoulder pads 206. The shoulder pads 206 are formed of foamed energy management material, e.g., EPP, EPS. FIGS. 1A and 2A show a helmet 100 having shoulder pads 206. FIGS. 1B and 2B show a helmet 100 of FIGS. 1A and 2A with the energy management liner 200, including the shoulder pads 206, removed to emphasize the outer shell lower edge 106 and recesses 124. Each of the shoulder pad recesses 124 is disposed on a respective left or right side of the helmet.

(27) The shoulder pads may be formed of a soft, pliable, energy-absorbing material that elastically deforms, such as a foam, textiles, plastic, or other suitable material, that may be covered by a covering material like leather, vinyl, cloth, textile, or other film or sheet of material.

(28) Each of the shoulder pads 206 is received in one of the shoulder pad recesses 124. The shoulder pads 206 extend outward and downward from the sides 112 of the helmet such that the shoulder pads 206 extend across at least a majority of the width 122 (FIG. 2B) of the outer shell lower edge 106. In some embodiments, the shoulder pads 206 extend further downward from the outer shell beyond the nominal lower edge line 108 (FIG. 3). With shoulder pads installed in the helmet, the shoulder of the wearer contacts a shoulder pad, instead of the outer shell, when the wearer's head and body move to a point that the helmet bumps into the shoulder. The shoulder pads alleviate the impact of the helmet to the wearer's shoulder.

(29) In particular embodiments, the height 216 of the shoulder pad above the nominal lower edge line 108 (FIG. 3) or between the nominal lower edge line 108 and the outer shell lower edge 106 may be in a range of 0-20 millimeters (mm), 0-10 mm, or 3-10 mm. The height 218 of the shoulder pad below the nominal lower edge line 108 (FIG. 3) may be in a range of 0-20 mm, 0-10 mm, or 3-10 mm.

(30) In particular embodiments, the distance 224 between a front of the shoulder pads and a front of the helmet may be in a range of 5-13 centimeters (cm) (or 2-5 inches) (FIG. 3). The distance 226 between a rear of the shoulder pads and a rear of the helmet (FIG. 3) may be in a range of 2.5-7.5 cm (or 1-3 in.).

(31) The shoulder pads may be in any desirable shape or have any desirable number of sides. In some instances, the shoulder pads may comprise a height H (FIG. 4B) in a range of 0.5-5.0 cm (or 0.2-2.0 in.), a length L in a range of 5-18 cm (or 2-7 in.), and a width W in a range of 1-4 cm (or 0.4-1.6 in.) (FIG. 4B). The width W is measured as the distance between a point in the outer side of the shoulder pad and a corresponding point on the inner side of the shoulder pad. The length L of the shoulder pad is measured as the distance between the front of the shoulder pad and the rear of the shoulder pad. The height H of the shoulder pad is measured as the distance between a point at the top surface of the shoulder pad and a corresponding point at a bottom surface of the shoulder pad. In the specific non-limiting embodiments illustrated in FIGS. 4A-4C, the shoulder pads are tapered such that a height H and a width W is greatest towards the middle or center of the length L, and then is tapered to a lesser height H and width W at the opposing ends of the length L. In other embodiments, the height H and the width W may be constant along the length L. The width of the shoulder pad may be the same as the width of the sidewall of the helmet body (e.g. the outer shell plus energy management liner, and optionally the comfort liner).

(32) Each shoulder pad may be a stand-alone piece and be coupled to the helmet body via friction, magnets, hook- and loop fasteners, snaps, glue, or other means known in the art. Shoulder pads may also be integrated with other components of the energy management liner or comfort liner, for example, the shoulder pads may be integrated with cheek pads.

(33) Shoulder pads 206 may be a part of a shoulder pad assembly 214, which forms part of the energy management liner 200. FIGS. 2A and 2B illustrate the placement of the shoulder pad assembly 214 relative to the outer shell 104 of the helmet 100. FIGS. 4A-4C illustrate an example shoulder pad assembly 214, showing the perspective, top, and side view of the shoulder pad assembly 214.

(34) A shoulder pad assembly 214 (FIG. 4C) comprises a first portion 202 of the energy management liner 200 (FIGS. 4C-5A), a second portion 204 of the energy management liner 200 (FIG. 4C, 5B), and one or more anchors 208 (FIGS. 5A-6B) connecting the first and second portions 202, 204 together. In the particular non-limiting embodiments shown in FIGS. 4C-5B, the shoulder pads 206 are be formed as part of the second portion 204. The shoulder pads 206 shown in FIGS. 4A and 4B extend sideways away from the remaining part of the shoulder pad assembly 214 so that the shoulder pads 206 can extend across a majority of the width of the outer shell lower edge. Anchors are not shown in the surface of the example assembled shoulder pad assembly 214 shown in FIGS. 4A-4C because one portion 207 of the anchors 208 is surrounded by the first portion 202 of the energy management liner 200, and the other portion 209 of the anchors 208 is surrounded by the second portion 204 of the energy management liner 200 (FIG. 5A). FIGS. 4C, 5A, and 5B depict the right-side views of the shoulder pad assembly or parts of the shoulder pad assembly 214. The corresponding parts on the left side of the shoulder pad assembly will be mirror images of those on the right side for most embodiments.

(35) The first portion 202 of the energy management liner 200 is formed of a first material. The second portion 204 of the energy management liner 200 is formed of a second material, different from the first material. The anchors are made of a third material that is harder than the first and second materials. In some embodiments, the first material is EPS and the second material is EPP. The anchors may be formed of plastic, metal, nylon or other material.

(36) The first portion 202 and the second portion 204 may be co-molded. In some embodiments, one or more anchors are used to help bind the first and second portions 202, 204 together. To assemble the energy management liner 200, one or more anchors are at least partially inserted into a first mold. A first material is then injected into the first mold and forms a first portion 202 of the energy management liner 200 with the anchors 208 extending out of the first portion 202 (FIG. 5A). After the first portion 202 is taken out of the first mold, at least the uncovered portions of the anchors, and in some cases portions or all of the first portion 202 of the energy management liner, and in some embodiments two (left and right) first portions 202, are placed inside a second mold. A second material is then injected into the second mold to form the second portion 204 of the energy management liner 200. The second portion 204 is formed around the portions of anchors uncovered by the first portion 202 and co-molded with the first portion 202. The order of making the first portion and the second portion may be reversed such that the second portion of the energy management liner is made before the first portion of the energy management liner.

(37) The anchors 208 comprise enlarged or extended arms or structures for the anchors to hold onto the first or second portions 202, 204 (FIGS. 6A and 6B). FIGS. 6A and 6B illustrate non-limiting examples of anchors 208a, 208b.

(38) The energy management liner 200 may further comprise a chin bar portion 210 (FIGS. 2A, 4A-4C, and 5B). The chin bar portion 210 extends into the chin bar 110 of the helmet body 102 (FIG. 2A). The first portions 202 of the shoulder pads may be joined together through a single chin bar portion 210 that extends through the chin bar 110 of the helmet body 102 to join the two first portions 202 of the respective shoulder pad assemblies, or the chin bar portions 210 may be separated. In either case, however, each shoulder pad assembly includes its own chin bar portion 210.

(39) The helmet 100 may further comprise cheek pad magnets 212. The cheek pad magnets 212 may be disposed on the first portion 202 of the energy management liner 200 (FIG. 4A-4B). The cheek pad magnets 212 may be disposed into the apertures 228 of the first portion 202 for installing the cheek pad magnets 212 (FIGS. 4C, 5A).

(40) Methods of assembling a helmet energy management liner are also provided herein. FIG. 7 illustrates an example method (400) of assembling a helmet energy management liner. The method 400 comprises placing one or more anchors made of a third material at least partially into a first mold (402). The method 400 further comprises injecting a first material softer than the third material into the first mold to form a first portion of the energy management liner of the helmet around at least part of each of the one or more anchors (404). The method 400 further comprises placing at least uncovered portions of the anchors into the second mold (406) and injecting a second material into the second mold to co-mold a second portion of the energy management liner onto the first portion (408). The second portion is formed around the portion of the anchors uncovered by the first portion of the energy management liner. The second material is different from the first material and the third material. In some embodiments, the first material is EPS and the second material is EPP.

(41) In some embodiments, injecting a second material into the second mold (408) includes forming at least two shoulder pads integral with the second portion of the energy management liner to form a shoulder pad assembly. The method 400 may further comprise mounting the shoulder pad assembly onto the helmet. The shoulder pads of the shoulder pad assembly extend from inside of the outer shell of the helmet and are received in one of the at least two shoulder pad recesses of the outer shell. In some embodiments, mounting the shoulder pad assembly further comprises mounting the shoulder pad assembly to the helmet with a chinbar portion of the second portion extending into a chinbar of the helmet body.

(42) This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended helmets and methods of assembling a helmet will become apparent for use with implementations of the apparatus and methods in this disclosure. In places where the description above refers to particular implementations of protective helmets, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other protective helmets.
