摘要： A carrying system adapted for use with breathing apparatus suitable for carrying one or more air cylinders for use in emergency situations by people such as fire- fighters and others who may be exposed to contaminated and hostile environments. The carrying system comprises a backplate (11) and a pair of straps(12) adapted to hold the backplate (11)on the back of a user when the carrying system is worn. The backplate (11)comprises at least one plate of a plastics material adapted both to provide impact protection to a user during use by at least partially absorbing and / or dispersing impact forces, and to deform resiliently in response to external forces imposed by bending and / or twisting of a user during use and then return substantially to its predetermined shape when not subjected to an external force.

摘要： A mask (10) for breathing apparatus has a seal (13) for sealing against and around the face of a user. The mask further includes a mask inlet (15) adapted to be placed in fluid communication with a supply of air, and a mask outlet (16) through which a user's exhaled breath is emitted, the mask outlet (16) including a one-way exhalation valve (22) including a valve closure member (23) mounted on a valve seat (25). An oronasal mask (14) in fluid communication with the mask inlet (15) and mask outlet (16) and positioned to engage, in use, over the nose and mouth of the wearer. The oronasal mask (14) is at least partially formed of material which is at least partially translucent, and an Illuminating LED (42) is in optical communication with the oronasal mask (14) so as to illuminate said oronasal mask (14).

摘要： A valve assembly (100) including a mask (106) end (104) and a supply end (102) is provided. The valve assembly (100) includes a housing assembly (120), an inhale valve (160), and an exhale valve (180). The housing assembly (120) defines a first air passageway (112) configured for inhalation (108) and a second air passageway (114) configured for exhalation (110). At least a portion of the second air passageway (114) is disposed peripherally around the first air passageway (112). The inhale valve (160) is configured to be biased to an open position when subject to a reduction in pressure due to inhalation, and to be biased to a closed position when subject to an increase in pressure proximate due to exhalation. The exhale valve (180) is configured to be biased to a closed position when subject to a reduction in pressure due to inhalation, and to be biased to an open position when subject to an increase in pressure due to exhalation.
