There is provided a facepiece that does not hinder the movement of a wearer. A facepiece that covers a face of a wearer, the facepiece including: a front surface plate that is a transparent plate-like member having a size that can cover the face of the wearer; and a rotation mechanism passing through the front surface plate on either a right or left side of the wearer and being rotatable with respect to the front surface plate.

A retractable respiratory mask of the present invention comprise a worn portion, a filter portion adapted to connect with a filter member, and a retractable portion; the retractable portion connected between the worn portion and the filter portion comprises a first bend portion, a second bend portion and a displacement section. The two bend portions are spaced apart from each other and the displacement section is connected between the two bend portions. The retractable respiratory mask of the present invention can change the relative position between the two bend portions by folding over the displacement section. The retractable respiratory mask shows an extended shape when the first bend portion and the second bend portion are orderly arranged in an extending direction, and conversely shows a contracted shape when two bend portions are arranged along the opposite direction. By doing so, the mask can be folded up to reduce entire volume.

There is provided a back carrier that does not hinder the movement of a wearer. A back carrier having a gas cylinder attached thereto, and carried on wearer's back, the back carrier including: a main body to which the gas cylinder is attached; and an adjuster including a regulator and a pressure demand valve attached to the main body and integrated with each other.

A system for eliminating odor is presented. The system has a nostril plug filter for inserting in to nostril barring odor. The system also has a bottle that has a liquid, a top and an inside. The bottle is squeezed to release a mist of the liquid. The mist from the liquid being sprayed upon the nostril plug filter. The nostril plug filter is inserted into a nostril of a person to eliminate smelling of the odor. The liquid may be scented, such as lavender, peppermint, vanilla, floral, etc. Further, the system may include a container, such as a case or a tube, for storing the nostril plug filter and protecting it from dirt, damage or being lost.

The invention relates to an oxygen mask (1) for an emergency oxygen supply of passengers in an aircraft, with a carrier (12), on which a breathing bag connection (5) for a breathing bag (11), an inhalation valve (3) and an exhalation valve (4) are provided, wherein the carrier (12) comprises at least two carrier parts (14, 15, 16) which are arranged pivotable to one another.

An emergency air supply system and method for delivering breathable air to an individual in need thereof. The system includes a wall mounted housing that contains an air tank, an inflatable bag, and an ocular respiratory mask. The air tank is removably connected to the inflatable bag, and the inflatable bag is connected to the ocular respiratory mask. During use, the inflatable bag is inflated by an air supply of the air tank, the inflatable bag is removed from the air tank, and the ocular respiratory mask, which remains connected to the inflatable bag, is worn by the individual in need of breathable air.

Embodiments relate generally to connectors for use with harness and backplate systems in an SCBA. An SCBA may comprise a backplate for holding a cylinder of air and a harness with straps operable to attach to the backplate. Applicants have developed a backplate connector that provides a reliable quick connection and disconnection for straps attached to a backplate. The connector may fit into a slot on the backplate. In some embodiments, a plurality of connectors may be used to connect a plurality of straps to the backplate. Additionally, the connector may comprise a clip or other attachment operable to secure one or more hoses of the SCBA. This design may prevent the air hoses being hooked accidently, and the attachment of the hoses may help to secure the connector into the slot of the backplate, reducing the change of the connector disconnecting during normal usage.
