A personal protection and ventilation system is provided. The system includes a gown having front and rear panels, a hood, and visor; a fan; an air tube; and a helmet. The fan is positioned between the wearer and a body-facing surface of the rear panel. The front panel and at least a portion of the hood are formed from a first material including a first spunbond layer, a spunbond-meltblown-spunbond laminate, and a liquid impervious elastic film disposed therebetween. The first material has an air volumetric flow rate of less than about 1 standard cubic feet per minute (scfm). The rear panel is formed from a second material including a nonwoven laminate having an air volumetric flow rate of about 20 scfm to about 80 scfm. Therefore, the fan is able to intake a sufficient amount of air from the environment through the rear panel to provide cooling/ventilation to the hood.

A visor mechanism for a safety helmet, in particular for emergency services, includes a visor, which is slidably mounted relative to an outer shell of the safety helmet in order to cover a front region of the safety helmet, and a visor adjuster, which is coupled to the visor so that the visor can be slid by a sliding actuation of the visor adjuster. The visor mechanism has a locking assembly coupled to the visor and the visor adjuster, which locking assembly, when locked, blocks the sliding of the visor, and which locking assembly (6), when released, allows the visor to slide. The locking assembly can be released by a release actuation of the visor adjuster. A safety helmet may include a visor mechanism of this type.

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.

A pivoting shield assembly for hats is revealed. The pivoting shield assembly includes mounting slots arranged at two sides of a hat, a pivot base mounted to each mounting slot, a first connecting rod and a second connecting rod each of which having one end pivotally connected to the pivot base and the other end pivotally mounted to a shield, and a pathway groove disposed on an inner side of the first connecting rod. The pivot base includes an elastic locking piece which is mounted and moveable in the pathway groove correspondingly. Thereby lifting up and pulling down of the shield are more precise and having different stages. The pivoting shield assembly for hats is practical.

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.

Disclosed is a pivot mechanism for a shield for a helmet, the pivot mechanism comprising a curved track having a first end and a second end; and a clamp slidingly engaged to the curved track, wherein the clamp is configured to attach to an end of the shield and slide along the track between a first position proximate to the first end of the curved track and a second position proximate to the second end of the curved track.

Provided is a facial protection apparatus including a main body having an opening area that is opened forward and being wearable by a user, a shield portion covering the opening area formed in the main body and detachably connected to the main body, and an opening/closing portion installed on the main body and opening/closing an insertion path of the shield portion that is inserted in the main body, so as to protect the face of the user against foreign matters during an operation and to have an improved convenience in use.

A protective helmet (1), including a shell (2), a cap (3) attached in the shell (2), and a movable face shield (4) attached to the shell (2) by at least one assembly arrangement, which includes: a rod (40) connected to the shell (2) in an articulated manner about a first substantially transverse axis (51) and a second substantially transverse axis (52); and a rail (55) positioned on the shield (4) and having at least one guide surface (59) that operates with at least one element (56, 58a, 58b) to guide the movement of the face shield (4) between a lowered and raised position and along, but spaced from, the shell (2).
