WAIST PAD BUMBER SYSTEM FOR SELF-CONTAINED BREATHING APPARATUS

摘要

A self-contained breathing apparatus (SCBA, 100) comprising a waist pad bumper system (200). The waist pad bumper system (200) may comprise a soft rubber gasket (220) located between the waist pad (204) and the backplate (202) of the SCBA (100), operable to compress to cushion the movement of the backplate (202) with respect to the waist pad (204); a hard rubber gasket (230) located between the waist pad (204) and the backplate (202) operable to compress to cushion the movement of the backplate (202) with respect to the waist pad (204); one or more magnets (214) located on the waist pad (204); and one or more magnets (210) located on the backplate (202) operable to interact with the one or more magnets (214) located on the waist pad (204), wherein the magnets (214) of the waist pad (204) have the same polarization as the magnets (210) of the backplate (202) and therefore repel each other.
