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.
