Blower appliance provided with a harness for carrying on the back

Blower equipment comprising:

• a carrying harness provided with a carrying frame with a dorsal support area arranged on a dorsal plane, the dorsal plane extending adjacent to the back of a carrier when the harness is worn on the back in a position of use of the blower equipment,
• at least one lateral blower fastener,
• a blower secured to the carrying frame by the blower fastener, and comprising a fan body with an air outlet arranged on an air-outlet axis, the blower including a nozzle, connected downstream of the air outlet by an elastic bellows with return effect, the elastic bellows having a return component, parallel to a spinal axis, with a first spinal return stiffness, the spinal axis being defined at an intersection of the dorsal plane with a spinal plane, perpendicular to the dorsal plane and passing through the vertebral column of a carrier when the harness is worn on the back in the position of use,
• and wherein:
• the blower fastener comprises an articulation having a return effect, tending to return the air-outlet axis of the air outlet of the fan body towards a rest position, the articulation having a return component, parallel to the spinal axis, with a second spinal return stiffness, the second spinal return stiffness being greater than the first spinal return stiffness.
