A headgear apparatus is disclosed comprising a molded headgear apparatus which includes a cushioned core component to provide impact resistance during an activity. The headgear is configured to be low-profile to reduce the loss of vision caused by thick headgear which extends away from the face. The headgear may be molded to the facial contour of the user to provide complete protection from cuts, scrapes, swelling, and impact encountered in impact sports, such as martial arts, football, or other sports wherein impact to the head region is possible.

The present disclosure describes clips for lanyards, such as hard hat lanyards. The clips include opposing teeth that move to a closed/clamped position to secure a lanyard to a user, such as to the clothes of a user. The clip includes a body, a lever and a grip. Opposing teeth are located on the grip and body. The clip includes multiple pivoting connections between the body, lever and grip. The teeth on the grip may lie along an arcuate path and/or may have a tooth depth that facilitates engagement with material such as clothing.

A head-mounted device capable of more highly accurately measuring the physical conditions of a wearer as a worker that are necessary for estimating the possibility of heat stroke is provided. A head-mounted device includes an outer shell; a first channel as a gap between a head of a wearer and the outer shell; a second channel provided in the outer shell and connected to the first channel; a fan configured to send air from one of the first channel and the second channel to the other; a salinity sensor configured to measure salt concentration of sweat of the wearer; a first humidity sensor configured to measure an absolute humidity of intake air entering one of the first channel and the second channel; and a second humidity sensor configured to measure an absolute humidity of exhaust air exiting from the other of the first channel and the second channel.

A hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a “bulge” or protrusion over the ear.

Systems and methods for selectively attaching an accessory mount to a helmet are disclosed. A carrier may be used to position the accessory mount on the helmet. The accessory mount may be positioned on the helmet without engaging the rim of the helmet. The carrier may be compatible with various accessory mounts to permit mounting of different accessories. The accessory mount may be a powered mount for attachment to a Night Vision Device (NVD) such as Enhanced Night Vision Goggles (ENVG), or the accessory mount may be a non-powered accessory mount.

A helmet lighting system includes a display attachable to a helmet which is selectively illuminated in response to receiving a wireless signal transmitted from a wireless transmitter operably coupled to a brake or direction signal light of the motorcycle. The display includes flexible base housing attachable to an outer surface of the helmet that at least partially houses an illumination module. A flexible applique overlies the illumination module and is at least partially transparent or translucent so as to pass light from LEDs of the illumination module therethrough. The applique is removably attachable to the base housing and/or the illumination module and may be replaced with other appliques having different logos or indicia.

A mounting device having a mounting assembly for mounting a pair of goggles to a helmet is provided. The mounting assembly is configured to provide at least three degrees of freedom of movement using one or more actuation mechanisms for locking and unlocking a position of the mounting device. The number of actuation mechanisms is less than a number of degrees of freedom. In some aspects, the number of actuation mechanisms is one. A rotation base connects the mounting assembly to the helmet, and a goggle linkage connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism, and a floating friction brake mechanism, are provided.

An inner buffering structure of a helmet comprising an air bladder, wherein the air bladder comprises a detachable inner-layer air bladder and an outer-layer air bladder, and the inner-layer air bladder is used for being in contact with a user's head; a plurality of ventilation openings is formed in the inner-layer air bladder and the outer-layer air bladder; the portions where the inner-layer air bladder and the outer-layer air bladder correspond to the ventilation openings are provided with inner convex edges extending towards the interior of the ventilation openings; a first air valve is arranged on the inner-layer air bladder, a second air valve is arranged on the outer-layer air bladder, and a reserved hole allowing the first air valve to pass through is formed in the outer-layer air bladder.
