The following is a tabulation of some prior art that presently appears relevant:
The present invention relates generally to any protective helmet, and more particularly a helmet for use in sports such as American football, lacrosse, hockey, baseball, motor cycling or bicycling; and a helmet used in workplaces such as construction sites and industrial plants.
Helmets and other protective headgear are commonly utilized to protect a wearer's head from injury. Typically, helmets are designed specifically for the particular sport or activity. Numerous sports, such as American football, hockey, and lacrosse, require players to wear helmets. Helmets are also recommended for motor cycling, bicycling, and hazardous workplaces and industrial plants.
American football helmets have evolved since the inception of football. In the early years of football, football players did not wear helmets or protective headgear. As the number of football player head injuries increased, helmets became a required item of equipment. One of the first instances of football headgear dates to 1896 when Lafayette College halfback George “Rose” Barclay began to use straps and earpieces to protect his ears.
The football helmet used prior to World War II was primarily a leather cap with ear flaps. Subsequent to World War II, a football helmet was introduced having a hard outer shell made of plastic with a web support mounted in the shell to space it from the player's head. The web support was subsequently replaced with a type of shock absorbing liner or padding.
In addition to the outer shell with interior padding, the conventional football helmet includes a face guard, having either upper or lower side mounts, and a chin protector or strap, that fits snugly about the chin of the player, in order to secure the helmet to the player's head.
In contact sports such as football, helmets provide players a substantial degree of protection against injury to their heads due to impact forces that may be sustained; however, a large number of head injuries and brain concussions, particularly g-force injuries, continue to occur. Rapid acceleration or deceleration of the head (g-forces) has been deemed to be the cause of many sports-related injuries and is the subject of growing concern. When contact is made with the conventional helmet, the rigid outer shell moves as a unit, compressing the padding between the head and the shell on the contact side of the helmet. After some initial compression, the padding begins to move the head. As the entire helmet and head move away from contact, the padding begins to rebound and places increasing force on the head. This process of compressing padding while gradually imparting an increasing load to the head is the method conventional helmets use to address g-force impacts.
Despite a large number of inventions to improve the design of protective helmets, it is still very desirable to have an improved protective helmet which provides increased and universal protection from impact forces sustained by the wearer. It is further desirable to have a protective helmet that provides a reduction of g-forces in any all directions. It is also desirable to provide an improved helmet for contact sports, non-contact sports, hazardous workplaces, and industrial plants. There is still a lot of room for improvements and a huge demand for better protective helmets that this invention provides.
The present application discloses a multi layer protective helmet comprising one hard shell (or two joined hard shells) and an energy absorbing layers. The shell (or outer shell) includes a crown portion, a front portion, a left side portion, a right side portion, and a rear portion, wherein each side portion has an ear flap with an ear opening, and wherein the outer shell has vent openings; and a faceguard secured to the outer shell by at least two faceguard connectors; and a chin protector with four chin strap attachments secured to the outer shell.
The shell (or the inner and outer shells) can be integrated with energy absorbing material to dampen energy received by the shell(s).
In this invention, the helmet has multi-layers of energy absorbing materials to dampen energy and reduce impacts, head injuries, and sports related concussions (SRC). Sports Related Concussions have become an international public health concern, affecting athletes of all ages in many sports especially in the American football. Therefore, there is a huge demand for better helmets to prevent or reduce head injuries throughout the World.
The material recommended for the hard shell (or shells) of the multi-layer protective helmet are: Acrylonitrile Butadiene Styrene (ABS) (Thermoplastic), Polycarbonates (Thermoplastic), Advanced Thermoset Resin (ATR), Fiberglass, Carbon Fiber, Kevlar, and Synthetic Reinforced Shell (SRS). Polycarbonates are ideal materials for helmet shells because they are lightweight, tough and exhibit good impact strength, even in extreme temperatures. Polycarbonates refer to a family of thermoset polymers that are widely used in manufacturing, for their mechanical performance and ease in manufacturing.
The material recommended for the energy-absorbing layers as of today's technology is the Sorbothane 70 Durometer, where Durometer is a unit of hardness. There is another candidate which is the Dow Corning 3179 Dilatant Compound. However, it was proven that Sorbothane 70 Durometer is superior to the Dow Corning 3179 Dilatant Compound in both force reduction and recovery from impact without any deformation. Future technologies may give us better energy absorbing materials.
The invented helmet complies with the National Football League (NFL) design constraints to achieve a high level of protection due to the severity of the American football, and to make the invented helmet wearable by the NFL players.
A better understanding of the present invention can be obtained when the following detailed description of the disclosed preferred embodiments is considered in conjunction with the following drawings, in which:
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
Referring now to the drawings, in which like reference numerals are used to refer to identical or similar elements, a first preferred embodiment of the multi layer protective helmet, generally referred to as reference numeral 100, is shown in

Although not shown, it is also to be understood that the protective helmet 100 may include such features that are well known and understood to those skilled in the art including a chin protector with a chin strap, a plurality of air vents located through the front, top, and back of the helmet 100 to allow for maximum air flow and to circulate the inside helmet air through the air vents, and in certain activities such as football, a face guard system is required to protect the player's face from any impact at the front of the helmet. Face guards and attachment devices for attaching the face guard to the helmet shell are well known to those skilled in the art. Face guards and attachment devices for attaching the face guard to the helmet shell are well known to those skilled in the art. A face guard system including a wire face guard, preferably made from steel, such as stainless or titanium, and covered by plastic, such as a powder coated plastic. The face guard is preferably pivotally attached to the upper front (forehead) portion of the helmet 100 with fasteners, typically screws, as are well known in the art.
It is the desire that the protective helmet of the present invention provides a degree of protection to its wearer by reducing the g-forces to the head upon impact. It is to be understood that dimensions, surface forms, and internal padding can be changed to accommodate enhanced protection, thus providing safer operation of the helmet. The protective helmet can also be used for various other sports and activities not mentioned previously including, but not limited to, skiing, auto racing, and military impact training exercises.
