Apparatus and associated methods relate to a body-worn unitary harness having a shoulder portion and a waist portion in tensile communication with one another, such that both the shoulder and the waist portions can be simultaneously adjusted using a single adjustment mechanism to conform to a wearer's body. In an illustrative embodiment, a length of webbing may thread through an angle-turning buckle and change direction therein. Tensile forces in the length of webbing may be directed in different directions on either side of the angle-turning buckle. A single clasp may facilitate both donning and doffing of the unitary harness. An implement connector may be coupled to a hip member and configured to connect an implement to the unitary harness. Various exemplary unitary harnesses may provide comfortable implement carrying capacity while automatically adjusting relative waist and shoulder lengths to accommodate a user's movements and positions.

One-belt harness

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.

Quick coupling for self-contained breathing apparatus harness and backplate

A harness may be used to carry a breathable air system. Generally, the harness may comprise at least one shoulder strap and a plurality of attachments configured to attach the at least one shoulder strap to the breathable air system. Additionally, the plurality of attachments may allow the breathable air system to be configured into a plurality of strap configurations. For example, the plurality of strap configurations may include a hip configuration, a waist configuration, a leg configuration, and/or a back configuration. In some configurations, an additional/accessory strap may be used to more securely carry the breathable air system in the plurality of strap configurations.

Harness design for respiratory system

Embodiments relate generally to a self-contained breathing apparatus (SCBA comprising a waist pad bumper system. The waist pad bumper system may comprise a soft rubber gasket located between the waist pad and the backplate of the SCBA, operable to compress to cushion the movement of the backplate with respect to the waist pad; a hard rubber gasket located between the waist pad and the backplate operable to compress to cushion the movement of the backplate with respect to the waist pad; one or more magnets located on the waist pad; and one or more magnets located on the backplate operable to interact with the one or more magnets located on the waist pad, wherein the magnets of the waist pad have the same polarization as the magnets of the backplate and therefore repel each other.
