The PAPR kit is an air-purifying respirator that uses a blower to force the ambient air through air-filtration media to the hood assembly to create positive air pressure. The PAPR kit is module in design and can be employed in multiple use configurations and applications. The PAPR kit comprises a PAPR unit, the PAPR unit may be removably mounted or coupled to a back region of a hood assembly and/or a waist belt. The PAPR kit may further comprise an integrated or removable battery pack that is easily retained and/or removed from the PAPR unit.

A pacifying personal protective device for a child includes a panel, which is attachable to a head of a child so that the panel is positioned over at least a mouth and a nose of the child. The panel reduces transmission of pathogens between the child and persons proximate to the child. A pacifying element is engaged to the panel and is positioned proximate to the mouth of the child. The pacifying element facilitates pacification of the child, thus increasing a likelihood that the panel will remain in position on the head of the child.

A face mask including shape memory materials to improve fit to the face and/or create a cavity in front of the mouth to facilitate breathing.

A system and method for implementation of an improved weld pattern for the retention of straps to a face mask, configured to maintain maximum strength of the strap(s) without the use of glue or complete encapsulation via fabric welds. Proximal welds are positioned above and below ends of the straps without contacting the strap itself. The proximal welds are horizontal welds along the primary axis of the straps. The proximal welds are configured to reinforce primary vertical welds disposed along the very ends of the straps. A strip of weldable material is disposed atop the ends of the straps to facilitate the implementation of the horizontal and vertical welds.

A facemask assembly can include an interior air filter that is replaceable and/or contains biocidal elements. The filter can capture exhaled H.sub.2O to activate silver ions creating a biocidal environment. In some embodiments, at least part of the facemask is made via additive manufacturing. A facemask frame assembly can create a pleated filter to increase surface area and bring the filter material closer to the mouth and nose. The facemask can include a facial skirt customized to the facial geometry of the wearer. The facemask can have a permanently sealed filter than can withstand boiling and autoclaving temperatures so the mask system can be sterilized without disassembly. In some embodiments, the facemask has a visible display of how many times the facemask has been sterilized. In some embodiments, the mask includes a RFID device that can transmit how many times the facemask has been sterilized.

A pendent face mask is adapted to transition between a facially protective state and a folded state. The pendent face mask includes a foldable, air-permeable facial cover, a plurality of guides, and a suspension system. The suspension system suspends the facial cover in the folded state from a user's neck, and adjustably secures the facial cover in contact with the user's face in the facially protective state. The suspension system includes left and right segments that are drawable to form left and right ear loops.

A respiration filtering face mask that can be washed and sterilized by common means and reused repeatedly comprised of a filtering component that is a laminate of at least one layer of particle filtering material and at least one layer of a microbe killing metallic woven cloth laminated together by adhesive or fusible material in a manner that allows low resistance to air flow, cut to a shape that is folded into a modified cone, a padding filled gasket that is continuously sealed to the outer edge of the filter cone, harness straps that are elastic and user adjustable for length and tension, and an attached shield to prevent fogging of eye ware. A method for making said anti-microbial filter and respiration filtering face mask.

A directional lock or a headgear or interface assembly has one or more directional locks that include a catch arrangement for initiating or assisting in movement of a lock member of the direction lock. In some configurations, the catch arrangement assists movement of the lock member in only a portion of a range of travel of the lock member. In some configurations, the directional lock has a housing and a sleeve and the catch arrangement has a catch arm carried by the sleeve. The catch arm includes a catch end that contacts the lock member, which can be a lock washer in some configurations.

A mounting rail assembly comprises a rail configured to be coupled to a helmet. The rail may include a rear surface and a front surface with a mounting groove extending along a length of the front surface. The mounting groove may be open outwardly from a front surface of the rail and be configured to couple to a first accessory device at two or more positions along the length of the rail. A recess may be proximate an edge of the mounting rail assembly. The recess may be open generally perpendicular to the mounting groove and configured to receive a second accessory device. At least a portion of the recess may be positioned between the mounting groove and the rear surface of the rail.

The present invention relates to a nose-fitting adjuster. Particularly, the present invention relates to a nose-fitting adjuster, which can seal, without directly and intensely compressing the nose and a peripheral portion thereof, the corresponding portion, for a device, such as masks, goggles, gas masks, and VR headsets, that includes a portion coming in close contact with the nose region.
