A harness (10) for use with breathing apparatus comprises: a back plate (11); two support straps (13, 14), each of which extends between an upper part of the back plate and a lower part of the back plate, the two support straps being disposed on opposite sides of a central axis of the back plate (11
A harness (10) for use with breathing apparatus comprises: a back plate (11); two support straps (13, 14), each of which extends between an upper part of the back plate and a lower part of the back plate, the two support straps being disposed on opposite sides of a central axis of the back plate (11); and a tension equalizing mechanism (15, 16; 30, 32) connected to the support straps and being arranged such that, when tension is applied to a first strap (13, 14) of the support straps, it acts to transfer the tension to the other, second strap (13, 14), thereby increasing the tension in the second strap, the tension equalizing mechanism being resiliently biased towards a neutral configuration.

What is claimed is: 1.

What is claimed is: 1. A harness for use with breathing apparatus, comprisinga back plate;two support straps, each of which extends between an upper part of the back plate and a lower part of the back plate, the two support straps being disposed on opposite sides of a central axis of the back plate; anda tension equalizing mechanism connected to the support straps and being arranged such that, when tension is applied to a first strap of the support straps, it acts to transfer the tension to the other, second strap, thereby increasing the tension in the second strap, wherein the tension equalizing mechanism comprises a tension accommodating member rotatably mounted to the back plate, and a biasing means that rotationally resiliently biases the tension accommodating member in a rotational direction such that the support straps are resiliently biased towards a neutral configuration;wherein the tension equalizing mechanism includes first and second tension accommodating members connected by a connecting element, wherein, when tension is applied to the first support strap, the first tension accommodating member acts to increase an effective length of the first support strap and to reduce the tension in the strap, and the tension is transferred via the connecting element to the second tension accommodating member, which acts to reduce an effective length of the second support strap and to increase the tension in the second support strap, wherein the first and second tension accommodating members are axially and rotatably mounted to the back plate about first and second rotational axis, respectively, and act to reduce or increase the tension in the first or second support straps by rotation about the first and second rotational axis, respectively.
