A protective headgear position and impact sensor is described for use with hard hats, helmets, or other headgear. Proximity sensors are used to detect whether the headgear is being worn by the user. In some versions of the invention, additional features determine the nature of a head impact and store data related to wear of the headgear by the user. Yet other features may allow the headgear to serve as a security device, allowing entry into a facility only if the headgear is in position and if it is properly associated with an authorized individual who is wearing the headgear

A multilayer shell for use in the construction of protective headgear, the shell including an outer layer, an inner layer, a middle layer disposed between the outer and inner layer which resiliently compresses in response to an impact to the outer layer, and an internal liner disposed inwardly of the inner layer. The middle layer includes a plurality of compressible members, which resiliently compress to absorb the energy of a direct impact to the outer layer and resiliently shear with respect to the inner layer in response to a tangential impact to the outer layer. The inner layer includes an open configuration, which reduces the weight of the shell, provides for greater heat ventilation from the head of the user, and permits for visualization of the compressible elements. The internal liner is formed from contourable materials which enhance user fit and comfort and reduce the weight of the protective headgear without compromising user safety.

The protective helmet includes a rigid outer shell where the shell includes an undulating cross-sectional profile. A layer of impact-energy-absorbing material is positioned adjacent to the shell. The undulating profile of the shell can be any type of load spreading undulating profile, such as that of a sinusoidal or triangular wave configuration. The undulating load-spreading profile can be on the inner surface of the shell, on the outer surface of the shell or the entire cross-section of the shell may be undulating. The unique undulating profile makes the shell more rigid and spreads the impact load across the surface of the shell to thereby spread the deformation of the padding layer to prevent the shell from bottoming out of the impact-energy-absorbing material during an impact. As a result, a safer and more effective protective helmet is provided.

A ratchet mechanism for the headband of a protective helmet or other headgear allows for adjustment of the size and fit of the headband. The headband has overlapping rear end portions which are enclosed in a housing, which is comprised of an outer substantially arc-shaped housing section joined to a inner substantially arc-shaped housing section. Also contained with the housing sections is an adjustment mechanism adapted to cause lateral movement of the overlapping rear end portions of said headband with respect to one another. The outer and inner housing sections are substantially segmented into multiple discrete portions such that the respective housing sections are flexible along defined boundaries between the discrete portions to provide for a better and more comfortable fit.

A protective headgear device including a fabric cap (102) into which a hard shell (120) of reinforced fibers is inserted. A foam liner 140 or foam inserts (1500) are secured to the hard outer shell 120 and serve a shock absorbing function. The foam liner (14) and / or foam inserts (120) include or form grooves and / or channels used to direct hot air towards the top center of the headgear assembly where the hot air can be vented through holes which extend through the cap (102) and hard outer shell (120). The holes may pass through the foam liner 140 or meet up with holes on channels in or between the foam inserts through which air can pass. The hard outer shell maybe thinnest on top and thicker on the left and right sides. The center front and rear may be the same thickness as the top of the hard shell.

A brow pad for the headband of a protective helmet or similar headgear is ultrasonically welded or similarly joined to itself through openings defined through the headband. By joining the brow pad to itself through the headband, the brow pad remains secured to the headband even after extensive usage. Furthermore, the openings defined through the headband provide some measure of ventilation and evacuation of accumulated moisture from the brow pad. Finally, by joining the brow pad to itself and through the headband, there are pockets of air that are trapped between the joined portions of the brow pad, which serve as air-filled “pillows,” providing some measure of comfort to the wearer.

Impact shock absorbing material to be incorporated into protective gear or clothing. The impact shock absorbing material is a laminated material, having a shear-thickening layer and a shock absorbing layer, that is a honeycomb material. The laminated material is incorporated into protective headgear, sports gear, clothing, and a host of other articles that are worn for protection against impact shock. The shear-thickening layer shunts the local impact forces over a greater area of the underlying shock absorbing layer, thereby reducing the force at the point of impact. The vertical walls of the honeycomb layer buckle under the incoming force, thereby diffusing the direction of force away from direct alignment with the body wearing the impact-shock-absorbing material. Protective gear made of the impact shock absorbing material significantly reduces forces imparted to the body as a result of a fall, blow, or other sudden impact.

A versatile protective headgear which is a close replica of a football helmet, fabricated from a lightweight, suitable foam material that is conformable and resilient, capable of absorbing energy and protecting the wearer from lacerations and / or contusions from incidental contact in outdoor sporting activities. The headgear provides warmth and protection from moisture in cold weather, but the internal design also provides sufficient ventilation for year around use. The foam material can be produced in a variety of colors and has a smooth external surface that will accept paint and decals for authentic team identification. The headgear may be held in place by a standard football chin strap and is designed to have a removable face mask. The authentic appearance and cold weather protection it provides makes it an effective and desirable head covering for all cold weather recreational and work activities, including attendance at football games. Its flexibility permits packing for travel and storage. The simple construction from one piece of material makes is easy and economical to manufacture.

This invention is directed to a protective headgear system which includes a relatively light weight, substantially rigid, headgear structure which may include an internal, adjustable headband. A fan mechanism is mounted on the headgear structure. A power supply selectively powers the fan. The system includes filter means which is attachable to the headgear structure to cover the structure. A facial shield is attachable to the headgear structure to cover the face of the wearer to maintain non-contaminating conditions relative to the wearer. A shield protector is attachable to the facial shield. A flexible cuff is attachable to the facial shield to enclose the lower opening of the lens and provide protection for the wearer.

A sensor module generates sensor data in response to an impact to protective headgear, wherein the sensor module includes an accelerometer and a gyroscope and wherein the sensor data includes linear acceleration data and rotational velocity data. A device processing module generates event data in response to the sensor data. A device interface sends the event data to a monitoring device when the device interface is coupled to the monitoring device.

The present invention generally relates to protective headgear worn by a user to protect his eyes, head, and face. More particularly, the present invention is directed to a protective headgear assembly used by welders and the like wherein a headgear strap can be tightened or loosened upon the ratcheting of a knob connected to the headgear strap. The headgear strap can also be automatically disengaged for removal of the headgear by pulling the knob away from the user's head.
