The prior art contains many examples of protective headguard systems. The prior art describes a variety of fit and retention systems.
Headguard fit and retention systems are intended to keep the headgear on the head during use, maintain fit and comfort while in use, protect desired areas during use, and allow the user to easily put on and take off the headgear when desired.
Fit and retention systems must deal with the basic characteristics of the human head: the generally spheroidal shape; the neck; and the various features such as the face, ears, frontal bone, occipital bone, or the parietal eminences.
Protective helmets use various means to improve retention and fit. For those with hard and stiff shells, compressible padding, padding inserts, adjustable suspension are some of the means by which different head sizes can be accommodated. Football, hockey, bicycle helmets, and construction hard hats would fall into this category. For headgear with soft flexible shells, such as the headgear used in boxing, the martial arts, or soccer, the shape of the entire piece of headgear can be altered with, for example, adjustment straps to help conform it to the shape of the head.
In many instances, however, additional retention means such as chinstraps become necessary. Chinstraps typically attach near the edges of the helmet close to the ears and either pass under the chin or over the chin. A fastening system such as a buckle or snap allows the user to fasten and unfasten the chinstrap.
Various means have been attempted to improve fit and retention to overcome the shortcomings of systems that rely primarily on the chinstrap. Doing so often requires balancing fit, retention, and comfort. With almost any headgear, retention can be improved by simply making the headgear fit tighter. For headgear such as knit winter hats or winter headbands this does not typically pose a problem. A knit winter hat can fit relatively tight without causing discomfort. The lightness, elasticity, and conformability of such headgear are likely reasons for this.
For many kinds of protective headgear, however, creating a tighter fit merely results in discomfort. An American football helmet with a tight fit can be very uncomfortable. The bulk, inelasticity of the headgear structure, and the pressure points created where padding is compressed to fit variations on the head's surface could be causes for this.
Alternatives to simply tightening the fit have been developed. Many bicycle helmets, for example, have devices that cradle the occipital bone. These systems are not intended to eliminate the chinstrap but are intended to prevent minor shifts during normal use and to reserve the chinstrap for events such as accidents. These systems rely on a retention system that applies pressure to selected points on the head. In the case of the bicycle helmets with the occipital cradle, what amounts to a triangular retention system is created. In this system pressure is applied to a set of points below the occipital bone, points above the occipital bone, and points approximately in the middle of the forehead. However, these systems still rely on a chinstrap for retention purposes. Therefore there is still a pressure point under the chin.

The present claimed invention comprises the features of claim 1.
The present claimed invention is intended to improve protection of the temple area 104 of a human head 100 with an athletic headguard 10. The shape of the human head 100, above the eye brows, is basically a cone. When any flat object, such as a headband or headguard 10, is wrapped around the head 100 it has a tendency to "slip or slide" upward exposing the temple area 104 of the human head 100. A straight edged headband cannot protect the temple area 104 without covering the ears 106 which would muffle sounds and communication. The temple protecting headguard 10 can be used for many purposes. For example, uses could include soccer or other activities where it is necessary to protect the temple area 104 of a human head 100 from impact of a ball or player. A lightweight, well-ventilated, snug fitting, and securely affixed headguard 10 to protect the temple area 104 is desirable.
The first embodiment of the present invention, depicted in
The bands 30 extend laterally from the front pad 20 and wrap around the head 100. When measuring from the longitudinally extending center line T which bisects the front pad 20, the upper bands 32 and 34 are a shorter lateral length that the lower bands 36 and 38. Left and right scallops 36s and 38s extend longitudinally downward from the left and right lower bands 36 and 38 respectively, and are positioned to protectively cover the right and left temple areas 104 without covering the ears 106 when the headguard 10 is worn.
Each of the four bands 30 are independently adjustable from each other. This allows a user to customize the length of all the bands 30 in order to position the left and right scallops 36s and 38s as desired and secure the headband 10 comfortably upon a human head 100.
The left and right upper bands 32 and 34 will wrap around a human head 100 and connect to the rear pad 50 creating a first tensioned circumferential line of retention. The headguard 10 remains flush against the head 100 along the first line of retention. A second tensioned circumferential line of retention is created when the left and right lower bands 36 and 38 are secured flush around the head 100. Because the circumference of the first line of retention is smaller than the second line, the headguard 10 remains flush upon the natural conical shape of a human head 100 thus minimizing the amount of slippage which occurs while wearing the headguard 10.
The scallops 36s and 38s include a protective padding material comprising closed cell foams of various kinds.
The left and right scallops 36s and 38s can also be encased in coverings. The coverings can be made of various kinds of materials such as fabric. For most applications, an elastic and highly breathable material would be most suitable. For example, a fabric such as Spandex® from Du Pont Company could be suitable for many applications. Many other fabrics such as CoolMax® from Invista could also be suitable. CoolMax® is a product that could aid in moisture management. Other materials such as mesh materials could be used alone or in combination with various fabrics.
Adjustment straps 42, 44, 46 and 48 (collectively straps 40) connect the left and right, upper and lower bands 30 to attachment areas 56 and 57 located on either side of the rear pad 50. The adjustment straps 40 can be made from an elastic material or stretchable foam to add additional tension to aid in retention of the headguard 10. Hook and loop tape 39 or a buckle (not shown) connects the adjustment straps 40 to the respective attachment area 56 or 57 on the rear pad 50. By adjusting the individual adjustment straps 40 all four bands 30 are independently adjustable to optimally fit the headguard 10 onto the human head 100.
The rear pad 50 can have a cup shape or eccentric dimple 52 with interior 51 and exterior 53 surfaces to better accommodate a user's occipital lobe 108 to allow the rear pad 50 to be secured flush to the back of the head. The rear pad 50 can also have a channel 54 running through the rear pad 50 to accommodate a user's hair or pony tail to extend through the channel 54 providing for a more comfortable and securely fitting headguard 10.
A second embodiment of the present invention is depicted in
The headguard 200 can function with or without the adjustment straps 246 and 248 as employed in the first embodiment. Without the adjustment straps 246 and 248, the bands 230 simply attach directly to the rear pad 250, such as via hook and loop tape 239 with the hook portion 239a on the distal end of the bands 236 and 238 cooperating with loop portions 239b covering the attachment areas 256 and 257 on the rear pad 250. However, stretchability of the headguard 10 could be somewhat more limited without the adjustment straps 246 and 248. The position of the scallops 36s and 38s protectively covering the temple areas 104 while not covering the ears 106 would remain relatively unchanged while the headguard 200 is being expanded or contracted. The left and right scallops 36s and 38s would still be positioned, configured and arranged to protectively cover the temple areas 104.
