Abstract
Embodiments of the invention provide a protective device that may reduce head and facial injuries resulting from forces such as rotational and linear accelerations. According to an illustrative embodiment of the invention a helmet assembly is provided that includes a helmet shell to which a chin guard assembly is attached. The chin guard assembly is disposed and configured to protect the underside of the wearer's chin and jaw and counter rotational acceleration created by impact to the underside of the wearer's 30 chin or jaw. This supplements protection afforded by traditional helmets that are designed to protect against linear accelerations but fail to address rotational acceleration that can impart angular motion between the brain and brainstem, sufficient to cause concussions.
Description
HELMET WITH CHIN GUARD
The present application claims priority to United States Provisional Patent Application 61/557,587, entitled, "Helmet with Chin Guard", filed November 9, 2011.
FIELD OF INVENTION
This invention relates to protective head gear.
BACKGROUND OF THE INVENTION
Conventional protective head gear, such as helmets to safeguard sports participants, military personnel and others engaging in high risk activities, is designed to protect the skull from head trauma by primarily addressing linear acceleration caused by impact to the head by another object. This approach has only been successful to a limited extent, in part because such devices fail to account for the rotational components of an impact to the head, such as is sustained in a hit to the underside of the chin and jaw.
In general terms, there are two main types of forces at play when an impact to the head occurs: 1) A linear force, which is caused by a straight and direct impact, and 2) a rotational force, which is slightly oblique and causes the head to rotate around its point of articulation, i.e. its neck, at the top of the spine as it is hit. Angular or rotational acceleration of the skull caused by impact with another object is a common, but often under recognized, cause of head trauma and injury. Accordingly, there is a need for a protective device that addresses the rotational impact to the skull as well as direct blunt trauma to the chin and jaw.
SUMMARY OF THE INVENTION
Embodiments of the invention provide a protective device that may reduce head and facial injuries resulting from forces such as rotational and linear accelerations.
According to an illustrative embodiment of the invention a helmet assembly is provided that includes a helmet shell to which a chin guard assembly is attached. The chin guard assembly is disposed and configured to protect the underside of the wearer's chin and jaw and counter rotational acceleration created by impact to the underside of the wearer's 30 chin or jaw. This supplements protection afforded by traditional helmets that are designed to protect against linear accelerations but fail to address rotational acceleration that can impart angular motion between the brain and brainstem, sufficient to cause concussions. The positioning of the chin guard assembly with respect to the helmet shell, and thus with respect to the wearer's chin, must be such that it may reduce the possibility 35 of concussion sustained by torque on the brainstem caused by rotational acceleration.
This is generally accomplished by providing protection to the underside of the wearer's chin from impact.
Additional features and embodiments will become apparent from the following 40 specification in conjunction with the drawings.

FIG. 8 is an enlarged view of a fastening assembly for securing a chin guard assembly to a helmet shell according to an illustrative embodiment of the invention.
FIGS. 1-4 depict a helmet assembly 100 according to an illustrative embodiment of the invention. Helmet assembly 100 includes a helmet shell 102 to which a chin guard assembly 104 is attached. Chin guard assembly 104 is disposed and configured to protect the underside of the wearer's chin and jaw and counter rotational acceleration created by 65 impact to the underside of the wearer's chin. This supplements protection afforded by traditional helmets that are designed to protect against linear accelerations but fail to address rotational acceleration. Rotational acceleration can impart angular motion between the brain and brainstem, sufficient to cause concussions. The positioning of chin guard assembly 104 with respect to helmet shell 102, and thus the wearer's chin, must be 70 such that it may reduce the possibility of concussion sustained by torque on the brainstem caused by rotational acceleration and blunt force trauma to the chin and jaw.
When aligned properly, chin guard assembly 104 accomplishes this goal, provided helmet assembly 100 is secured adequately to the wearer.
75 Chin guard assembly 104 includes a rigid expanse 106 extending from the helmet shell right side 108 to the helmet shell left side 110 and disposed on the front side of the wearer. "Front side" is used in a general sense and thus, includes rigid expanse 106 disposed to protect the underside of the chin and jaw. Rigid expanse 106 is attached at a first end to helmet shell right side 108 and attached at a second end to helmet shell left 80 side 110 and disposed to protect against impact to the underside of a wearer's chin and jaw. Rigid expanse 106 may or may not pivot with respect to helmet shell 110 at the attachment locations on the helmet shell right and left sides 108, 110.
Preferably chin guard assembly 104 is adjustable with respect to helmet shell 102.
85 Preferably rigid expanse 106 is shaped to generally follow a wearer's chin. A preferred shape is that which maximizes a player's range of motion in lateral flexion and rotation while still providing the desired protection from injury caused by impact to the underside of the chin.
90 Rigid expanse 106 has a right elongated member 112 attached to the helmet shell right side 108 and a left elongated member 114 attached to the helmet shell left side 110. One or both of the elongated members 112, 114 is attached by a fastening assembly having a sleeve 116 attached to helmet shell 102 into which a portion of an end of one of elongated members 112, 114 is disposed. A first stop 118 is provided at the end of the 95 elongated member. First stop 118 may be for example, a cap such as shown in FIG. 1, a curved portion 220 of an elongated member 212, such as shown on helmet 200 in FIG. 5, or a cylindrical component 180 with a set screw 182 disposed about an elongated member 184 such as shown in FIG. 8. First stop 118 is designed to inhibit removal of chin guard 104 from sleeve 116. Similarly, first stop 220 is designed to inhibit removal of chin guard 100 204 from sleeve 216.
Helmet assembly 100 may include a spring 122 disposed about a portion of the end of elongated member 112, 114 between first stop 118 and sleeve 116.
Alternatively, a spring can be omitted such as shown in FIG. 5.
Helmet assembly 100 may also include a second stop 124 disposed about a portion of the end of elongated member 112, 114 on a side of sleeve 116 opposing first stop 118/120.
Second stop 124 can be adjustable along the elongated member. Adjustability may be provided for example by use of a set screw 126. The first stop can also be adjustable 110 along the elongated members.
The fastening assembly for attaching elongated members 112, 114 as described above allows the chin guard assembly to be pulled away from a wearer's face to facilitate removal of helmet assembly 100. The fastening assembly may be spring-loaded.
Springs 115 122 draw chin guard assembly back toward the wearer when helmet assembly 100 is in place on the wearer. Second stop 124 can protect against chin guard assembly being pushed into a wearer's neck.
The chin guard assembly may also be rotatable with respect to the helmet shell. For 120 example, chin guard assembly 702 shown in FIG. 7 can be rotatable at fastening mechanism 704, by virtue of pivots incorporated therein. Chin guard assembly includes a rigid expanse in the form of a single bar 712 without attachment to face mask 706. A strap 708 with a cupped chin portion 710 is proved to secure the helmet assembly to a wearer. Bar 712 is curved at its distal end 714 to reduce the possibility of bar 712 125 disengaging from helmet shell 716. A stop 718 is provided to further eliminate the possibility of components separating from one another.
Helmet assembly 100 may include a face mask 128, or not as shown in FIG. 6. If a face mask is provided, chin guard assembly 106 may be attached to face mask 128. In an 130 illustrative embodiment of the invention, chin guard assembly 104 is pivotally attached to face mask 128. An illustrative attachment apparatus includes one or more bars 130, 132 rotatable about a substantially horizontal bar 134 of face mask 128, and/or rotatable about rigid expanse 106. When bars 130, 132 are rotatable about a component of face mask 128, such as horizontal bar 134, and also rotatable about a component of the chin guard 135 assembly such as rigid expanse 106, further protection may be afforded from the chin guard assembly rotating upwards. Bars 130, 132 may also provide further protection from facial trauma. One or more of bars 130, 132 can be releasably attached to horizontal bar 134 or other portion of face mask 128 or rigid expanse 106 to further facilitate removal of helmet assembly 100 from a wearer, or to remove chin guard assembly 104 from helmet 140 assembly 100.
FIGS. 3 and 4, for example, show spacer components 190, 192, 194, which are provided to hold the position of bars 130, 132 so that the bars remain in a desired position with respect to horizontal bar 134 of face mask 128 and rigid expanse 106 of chin guard 145 assembly 104. This can be particularly beneficial when chin guard assembly 104 is rotated. Other mechanisms to position the components can also be used. A
further example includes notches and bumps for example, that inhibit sliding of bars 130, 132 along bars in face mask 128 and/or chin guard assembly 104. Spacer components can also be used in other areas where moveable parts need to retain certain relative positions.
150 Another example of spacer elements are parts 196, 198 shown in FIG. 5.
Spacer components may be for example, coils or springs formed of an elastomer such as silicone elastomers sold under the trademark Silastic0. They can also be made of a compressive material such as a foam or a non-compressive material. Coiled components 155 are advantageous because they may slide easily along a bar, yet keep a preferred relative distance between parts. Spacer components that can be easily cut and put in place can provide a user with the ability to customize the apparatus. Properly spacing carious components of the helmet apparatus may reduce head and facial injuries.
160 Helmet assembly 100 can have a chin strap assembly 136, as shown in FIGS. 1 ¨ 4 for example. Chin strap assembly 136 can include one or more straps 138, 140 attached to shell 102. The straps may include a rigid, non-rigid or semi-rigid cupped component 142. The helmet assembly of claim 1 further comprising a chin strap coupled to the helmet shell for securing the helmet assembly in place on a wearer. Chin straps 138, 140 165 can be used to help keep chin guard assembly 104 in place by, for example engaging strap 138 around elongated members 112, 114.
Alternatively, as shown in FIG. 6, a strap 144 can be included without a cupped portion attached thereto. The helmet assembly 170 shown in FIG. 6 has a cupped portion 170 incorporated with chin guard assembly 148. Cupped portion 146 fits against a wearer's chin. Cupped portion 146 is attached to elongated members 150, 152, which in turn are attached to helmet shell 160 by fastening mechanism 154. Elongated members 150, 152 can slide within sleeve 162 to facilitate removal of the helmet assembly and have a stop 156 to keep chin guard assembly 148 from detaching entirely from helmet shell 160.
175 Sleeve 162 may or may not pivot with respect to helmet shell 160. Stop 156 can be removable from the elongated members to fully remove chin guard assembly 148 from helmet shell 170.
The chin guard assembly can be configured to be an add-on component or accessory to 180 an existing helmet to supplement the protection provided by the helmet protecting the underside of the wearer's chin against impact thereto. Preferably the chin guard assembly accessory will include fastening mechanisms that can be incorporated into existing parts of the existing helmet. For example, snaps and sleeves can serve to accept complimentary components on the chin guard assembly accessory. Adapter components 185 can be included, for example to space the elongate members from the helmet shell to allow proper movement and securing of the chin guard assembly. An example of which is part 170 as seen in FIGS. 1 and 3.
A helmet accessory may include elements to attach the chin guard assembly to a face 190 mask that may be present on the existing helmet. For example, bars such as 130, 132 shown in FIG. 3 may be included. Spacer components, such as parts 190, 192, 194 may also be included.
The helmet shell to which the chin guard is attached should fit firmly and sit squarely on 195 the wearer's head. The front of the helmet should be within about one half inch of a wearer's eyebrows to provide protection to the forehead. If a chin strap is used to secure the helmet assembly to the wearer there should be no or minimal slack. Padding within the helmet shell can afford beneficial protection and aid in a firm, and possibly adjustable fit. If padding is included, it should provide a comfortable amount of pressure on the 200 head.
Rigid components of the helmet assembly can be plastic or metal for example, provided they have the impact resistance desired and are durable enough to withstand the application to which they are applied.
205 Although specific types of helmets are shown in the figures, the helmet assemblies can be used for and designed for various sports, including for example, football, lacrosse, skateboarding, skiing, snowboarding, motor cross, hockey and cycling. Which specific configuration and combination of components described will depend, at least in part, on the application of the helmet and the materials used to form the chin guard apparatus.
210 The magnitude and direction of the impact expected will require particular configurations and materials to meet the needs of the wearer.
While the invention has been described by illustrative embodiments, additional advantages and modifications will occur to those skilled in the art.
Therefore, the 215 invention in its broader aspects is not limited to specific details shown and described herein. Modifications may be made without departing from the spirit and scope of the invention. For example, embodiments of the invention may be implemented on helmets of various types, such as those for different sports or other activities.
Accordingly, it is intended that the invention not be limited to the specific illustrative embodiments, but be 220 interpreted within the full spirit and scope of the appended claims and their equivalents.
Various embodiments of the invention have been described, each having a different combination of elements. The invention is not limited to the specific embodiments disclosed, and may include different combinations of the elements disclosed or omission of some elements and the equivalents of such structures.

Figure 7 depicts a further helmet assembly having a chin guard assembly not directly engaged with a face mask according to an illustrative embodiment of the invention.
FIG. 8 is an enlarged view of a fastening assembly for securing a chin guard assembly to a helmet shell according to an illustrative embodiment of the invention.
FIGS. 1-4 depict a helmet assembly 100 according to an illustrative embodiment of the invention. Helmet assembly 100 includes a helmet shell 102 to which a chin guard assembly 104 is attached. Chin guard assembly 104 is disposed and configured to protect the underside of the wearer's chin and jaw and counter rotational acceleration created by 65 impact to the underside of the wearer's chin. This supplements protection afforded by traditional helmets that are designed to protect against linear accelerations but fail to address rotational acceleration. Rotational acceleration can impart angular motion between the brain and brainstem, sufficient to cause concussions. The positioning of chin guard assembly 104 with respect to helmet shell 102, and thus the wearer's chin, must be 70 such that it may reduce the possibility of concussion sustained by torque on the brainstem caused by rotational acceleration and blunt force trauma to the chin and jaw.
When aligned properly, chin guard assembly 104 accomplishes this goal, provided helmet assembly 100 is secured adequately to the wearer.
75 Chin guard assembly 104 includes a rigid expanse 106 extending from the helmet shell right side 108 to the helmet shell left side 110 and disposed on the front side of the wearer. "Front side" is used in a general sense and thus, includes rigid expanse 106 disposed to protect the underside of the chin and jaw. Rigid expanse 106 is attached at a first end to helmet shell right side 108 and attached at a second end to helmet shell left 80 side 110 and disposed to protect against impact to the underside of a wearer's chin and jaw. Rigid expanse 106 may or may not pivot with respect to helmet shell 110 at the attachment locations on the helmet shell right and left sides 108, 110.
Preferably chin guard assembly 104 is adjustable with respect to helmet shell 102.
85 Preferably rigid expanse 106 is shaped to generally follow a wearer's chin. A preferred shape is that which maximizes a player's range of motion in lateral flexion and rotation while still providing the desired protection from injury caused by impact to the underside of the chin.
90 Rigid expanse 106 has a right elongated member 112 attached to the helmet shell right side 108 and a left elongated member 114 attached to the helmet shell left side 110. One or both of the elongated members 112, 114 is attached by a fastening assembly having a sleeve 116 attached to helmet shell 102 into which a portion of an end of one of elongated members 112, 114 is disposed. A first stop 118 is provided at the end of the 95 elongated member. First stop 118 may be for example, a cap such as shown in FIG. 1, a curved portion 220 of an elongated member 212, such as shown on helmet 200 in FIG. 5, or a cylindrical component 180 with a set screw 182 disposed about an elongated member 184 such as shown in FIG. 8. First stop 118 is designed to inhibit removal of chin guard 104 from sleeve 116. Similarly, first stop 220 is designed to inhibit removal of chin guard 100 204 from sleeve 216.
Helmet assembly 100 may include a spring 122 disposed about a portion of the end of elongated member 112, 114 between first stop 118 and sleeve 116.
Alternatively, a spring can be omitted such as shown in FIG. 5.
Helmet assembly 100 may also include a second stop 124 disposed about a portion of the end of elongated member 112, 114 on a side of sleeve 116 opposing first stop 118/120.
Second stop 124 can be adjustable along the elongated member. Adjustability may be provided for example by use of a set screw 126. The first stop can also be adjustable 110 along the elongated members.
The fastening assembly for attaching elongated members 112, 114 as described above allows the chin guard assembly to be pulled away from a wearer's face to facilitate removal of helmet assembly 100. The fastening assembly may be spring-loaded.
Springs 115 122 draw chin guard assembly back toward the wearer when helmet assembly 100 is in place on the wearer. Second stop 124 can protect against chin guard assembly being pushed into a wearer's neck.
The chin guard assembly may also be rotatable with respect to the helmet shell. For 120 example, chin guard assembly 702 shown in FIG. 7 can be rotatable at fastening mechanism 704, by virtue of pivots incorporated therein. Chin guard assembly includes a rigid expanse in the form of a single bar 712 without attachment to face mask 706. A strap 708 with a cupped chin portion 710 is proved to secure the helmet assembly to a wearer. Bar 712 is curved at its distal end 714 to reduce the possibility of bar 712 125 disengaging from helmet shell 716. A stop 718 is provided to further eliminate the possibility of components separating from one another.
Helmet assembly 100 may include a face mask 128, or not as shown in FIG. 6. If a face mask is provided, chin guard assembly 106 may be attached to face mask 128. In an 130 illustrative embodiment of the invention, chin guard assembly 104 is pivotally attached to face mask 128. An illustrative attachment apparatus includes one or more bars 130, 132 rotatable about a substantially horizontal bar 134 of face mask 128, and/or rotatable about rigid expanse 106. When bars 130, 132 are rotatable about a component of face mask 128, such as horizontal bar 134, and also rotatable about a component of the chin guard 135 assembly such as rigid expanse 106, further protection may be afforded from the chin guard assembly rotating upwards. Bars 130, 132 may also provide further protection from facial trauma. One or more of bars 130, 132 can be releasably attached to horizontal bar 134 or other portion of face mask 128 or rigid expanse 106 to further facilitate removal of helmet assembly 100 from a wearer, or to remove chin guard assembly 104 from helmet 140 assembly 100.
FIGS. 3 and 4, for example, show spacer components 190, 192, 194, which are provided to hold the position of bars 130, 132 so that the bars remain in a desired position with respect to horizontal bar 134 of face mask 128 and rigid expanse 106 of chin guard 145 assembly 104. This can be particularly beneficial when chin guard assembly 104 is rotated. Other mechanisms to position the components can also be used. A
further example includes notches and bumps for example, that inhibit sliding of bars 130, 132 along bars in face mask 128 and/or chin guard assembly 104. Spacer components can also be used in other areas where moveable parts need to retain certain relative positions.
150 Another example of spacer elements are parts 196, 198 shown in FIG. 5.
Spacer components may be for example, coils or springs formed of an elastomer such as silicone elastomers sold under the trademark Silastic0. They can also be made of a compressive material such as a foam or a non-compressive material. Coiled components 155 are advantageous because they may slide easily along a bar, yet keep a preferred relative distance between parts. Spacer components that can be easily cut and put in place can provide a user with the ability to customize the apparatus. Properly spacing carious components of the helmet apparatus may reduce head and facial injuries.
160 Helmet assembly 100 can have a chin strap assembly 136, as shown in FIGS. 1 ¨ 4 for example. Chin strap assembly 136 can include one or more straps 138, 140 attached to shell 102. The straps may include a rigid, non-rigid or semi-rigid cupped component 142. The helmet assembly of claim 1 further comprising a chin strap coupled to the helmet shell for securing the helmet assembly in place on a wearer. Chin straps 138, 140 165 can be used to help keep chin guard assembly 104 in place by, for example engaging strap 138 around elongated members 112, 114.
Alternatively, as shown in FIG. 6, a strap 144 can be included without a cupped portion attached thereto. The helmet assembly 170 shown in FIG. 6 has a cupped portion 170 incorporated with chin guard assembly 148. Cupped portion 146 fits against a wearer's chin. Cupped portion 146 is attached to elongated members 150, 152, which in turn are attached to helmet shell 160 by fastening mechanism 154. Elongated members 150, 152 can slide within sleeve 162 to facilitate removal of the helmet assembly and have a stop 156 to keep chin guard assembly 148 from detaching entirely from helmet shell 160.
175 Sleeve 162 may or may not pivot with respect to helmet shell 160. Stop 156 can be removable from the elongated members to fully remove chin guard assembly 148 from helmet shell 170.
The chin guard assembly can be configured to be an add-on component or accessory to 180 an existing helmet to supplement the protection provided by the helmet protecting the underside of the wearer's chin against impact thereto. Preferably the chin guard assembly accessory will include fastening mechanisms that can be incorporated into existing parts of the existing helmet. For example, snaps and sleeves can serve to accept complimentary components on the chin guard assembly accessory. Adapter components 185 can be included, for example to space the elongate members from the helmet shell to allow proper movement and securing of the chin guard assembly. An example of which is part 170 as seen in FIGS. 1 and 3.
A helmet accessory may include elements to attach the chin guard assembly to a face 190 mask that may be present on the existing helmet. For example, bars such as 130, 132 shown in FIG. 3 may be included. Spacer components, such as parts 190, 192, 194 may also be included.
The helmet shell to which the chin guard is attached should fit firmly and sit squarely on 195 the wearer's head. The front of the helmet should be within about one half inch of a wearer's eyebrows to provide protection to the forehead. If a chin strap is used to secure the helmet assembly to the wearer there should be no or minimal slack. Padding within the helmet shell can afford beneficial protection and aid in a firm, and possibly adjustable fit. If padding is included, it should provide a comfortable amount of pressure on the 200 head.
Rigid components of the helmet assembly can be plastic or metal for example, provided they have the impact resistance desired and are durable enough to withstand the application to which they are applied.
205 Although specific types of helmets are shown in the figures, the helmet assemblies can be used for and designed for various sports, including for example, football, lacrosse, skateboarding, skiing, snowboarding, motor cross, hockey and cycling. Which specific configuration and combination of components described will depend, at least in part, on the application of the helmet and the materials used to form the chin guard apparatus.
210 The magnitude and direction of the impact expected will require particular configurations and materials to meet the needs of the wearer.
While the invention has been described by illustrative embodiments, additional advantages and modifications will occur to those skilled in the art.
