A bicycle helmet adapted to be used with eyewear includes an impact-absorbing body, a resilient wiper, and an alignment feature. The impact-absorbing body has a convex exterior surface and a concave interior surface adapted to be positioned on a user's head. The impact-absorbing body further includes an aperture formed in the exterior surface and dimensioned to permit insertion of a portion of the eyewear into the aperture along an insertion axis. The resilient wiper is positioned at least partially in the aperture and arranged to engage the portion of the eyewear upon insertion into the aperture. The alignment feature defines at least a portion of the aperture and is oriented to guide the portion of the eyewear toward the resilient wiper.

An integrated helmet includes: a helmet body, defining a wearing space, a flip cover coupled pivotally to the helmet body; a pair of glasses, configured on the helmet body and positioned relatively inside the flip cover, and generating a virtual reality image; and a first filter device, configured inside the helmet body. The integrated helmet 1 is provided with the flip cover to protect the smart glasses inside the flip cover, and can generate interactive VR images; the helmet body is provided with the first filter device to filter suspended particles in the air, such as viruses, dust, impurities, etc., achieving the improved epidemic prevention.

An air purifying device including means for reducing air resistance between the air filtering elements and the target locations for the purified air. Reduced air resistance lowers the energy consumed by the device, thereby reducing its size and weight as well as improving ease of integration with a variety of head gear.

A chin cup that has a hard outer cup and a soft inner cup that may be removable from the outer cup. The inner cup has a peripheral edge extending beyond the edges of the outer cup. Three strap guides, allow a strap to slide through. A one size fits all design includes a central indentation that extends upward toward a top central portion of the cups as well as a central narrowing longitudinally of the cups. Aligned vent holes in the inner and outer cups let the user's chin breathe. The cups have an arcuate longitudinal arch shape. Various embodiments include a boss and hole design that has buttons or mushroom caps that prevent the separation of the cups when not in use and an overmold one piece chin cup embodiment with the soft inner cup imbedded in the hard outer cup.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

The air-conditioned helmet is a protective structure. The air-conditioned helmet is configured for use with an individual. The air-conditioned helmet forms a protective shell around the head of the individual. The air-conditioned helmet is a temperature-controlled space within the protective space formed by the air-conditioned helmet. The air-conditioned helmet comprises a helmet structure, cooling structure, and a control circuit. The control circuit and the cooling structure attach to the helmet structure. The cooling structure controls the temperature of the protective interior space formed by the helmet. The control circuit: a) controls the temperature of the protective space formed by the helmet structure; and, b) tracks and announces the GPS coordinates into the protective space formed by the helmet structure.

A helmet for protecting the head of a user may include at least one liner comprising an inner surface and a lower edge surrounding the inner surface at a helmet opening configured to receive a head of a helmet wearer. At least two coupling points may be located on the inner surface proximal to the lower edge. At least one flexible forehead strap may follow the lower edge of the energy management layer and may be inwardly offset from the inner surface. At least two prongs may be coupled to, and slidably extend between, the flexible forehead strap and the at least two coupling points, respectively. A continuous gap between the inner surface and the flexible forehead strap may be provided by an offset created by the at least two prongs, the at least two prongs flexibly maintaining the offset.

A protective system for respiration, and a management method facilitates stably supplying filtered air for safety such that the equipment management or the safety management can be performed remotely. The protective equipment includes a main body that covers the face of an operator, a fan unit including an air filter and an electric fan, a detecting section, a first control section, and a first communication section. The detecting section detects a physical quantity concerning at least one of a work environment of the operator, an action state of the operator, and an operation state of the electric fan. The first control section controls the electric fan based on a detection result of the detecting section. The first communication section transmits first information indicating a detection result of the detecting section or second information concerning an operation amount on a control target of the first control section to an external device.
