A helmet comprises a shell defining a shell ventilation aperture and an inner liner securable within the shell. The inner liner defines an inner liner ventilation aperture and a recessed track. A ventilation control includes a slider plate and a boss disposed on the slider plate. The boss is configured to be frictionally retained within the recessed track while providing for the slider plate to be reversibly displaced along the recessed track from a first position in which the slider plate blocks a flow of air through the inner liner ventilation aperture to a second position in which the slider plate permits the flow of air through the inner liner ventilation aperture. The slider plate is configured to be reversibly displaced between the first and second position by a force applied upon a lower surface of the slider plate from within the helmet.

A helmet for receiving the head of a hockey or lacrosse player, the helmet having an outer shell and an inner lining covering at least partially the inner surface of the outer shell. In one embodiment, the helmet comprises a skeleton at least partially covered by the inner lining, a movable occipital pad and movable temple pads. The inner lining can be made of an absorptive material such as foam, expanded polypropylene or expanded polyethylene and can be overmolded onto the skeleton. The occipital pad and the temple pads may be arranged with an inward bias so as to help the helmet self-adjust to provide an advantageous fit on the player's head. In some embodiments, the outer shell and skeleton, or the outer shell and the inner lining, cooperate to define a ventilation system.

The present invention relates to the technical field of head protection equipment, in particular to a wearable head-protecting safety device, including a helmet body provided with oppositely arranged mounting seats on both sides near the lower edge thereof and a quick-release adapter assembly in form of a mask structure, wherein the quick-release adapter assembly is provided with a quick-release mechanism cooperating with the mounting seat at both ends near the upper edge thereof, the quick-release mechanism being relatively rotatable and detachably connected to the mounting seats, and wherein the quick-release adapter assembly is a grinding flip assembly or a welding flip assembly. It is possible to achieve switching of various types of masks through the quick-release adapter assembly detachably connected to the helmet body. Compared with prior art, the present invention can be applied to various scenarios through mask switching, improving the applicability of the wearable head-protecting safety device.

A ballistic armor helmet of parts which allow the helmet to be configured for particular uses and threats. The ballistic armor helmet is provided with two side wings which are fastened, removably or otherwise, to the helmet. Each side wing is fashioned of ballistic material and has a vertical part which extends downwardly to a position below the user's ear, and a front part which projects frontwardly from the vertical part to shield a portion of the user's cheek and provide additional sideward protection. With both side wings in place the front of the user's face is still unobstructed, as there is a substantial gap between the front parts of the side wings, leaving the user free to speak, eat, and breath without significant obstruction. The side wings may be attached by one or more fasteners.

A bicycle helmet for protecting the head of a wearer includes an outer shell and an energy dissipating inner layer coupled to the outer shell. The inner layer defines an inner surface, and front attachment locations are inwardly offset from the inner surface substantially at a frontal portion of the helmet. Rear attachment locations are inwardly offset from the inner surface substantially at a rear portion of the helmet. An internal ventilation system is supported by the front attachment locations and the rear attachment locations. The internal ventilation system is configured for direct engagement with the head of the wearer for supporting the helmet upon the head of the wearer. The internal ventilation system provides a gap between the head of the wearer and the inner surface. The gap allows ventilating air to flow over a substantial extent of the wearer's head and within the helmet.

A helmet/hood assembly includes a housing, a support ring subassembly configured to hold the assembly on a human head, a face shield, and a flexible hood attached to the housing and to the face shield, with the assembly being received, stored, used, and disposed as a single unit. The support ring subassembly pivots on the housing between a position suitable for shipping and storing the assembly and a position in which the assembly is worn. An accessory light powered by a battery may be held in place on the housing by magnetic attraction through the hood.

A safety helmet fan system includes a fan housing carrying a first fan on a first side of the fan housing and a second fan on a second side of the fan housing and configured to be mounted, by a mount connector located between the first side and the second side, on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell.

Various hard hat fan systems are provided. In a certain embodiment, fan system includes an impact absorbing layer with a channel that defines a recessed surface which extends into the impact absorbing layer away from an inner surface of a shell of a hard hat. Together, the inner surface of the shell and the recessed surface define a duct configured to provide fluid communication between an inlet of the channel and an air vent positioned along the channel. In another embodiment, fan system includes a mounting bracket with first and second cam levers which may be actuated into a locked position, and first and second channels. When in the locked position, the first and second cam levers bias the edges of a mounting ridge of the shell against the first and second channels of the mounting bracket such that the mounting bracket is retained on the shell.
