Abstract: Harness adjustment assemblies for user-worn electrical appliances and connection systems for the same are disclosed. In one aspect, a system includes an electrical appliance including a housing defining a recess, a track removably connected to the housing within the recess, a harness adjustment assembly connected to the housing by the track, and a harness assembly configured to be worn by a user of the electrical appliance to facilitate carrying the electrical appliance. The harness adjustment assembly includes an actuator assembly movable and selectively repositionable along the track. The harness assembly is connected to the actuator assembly such that the harness assembly is selectively repositionable relative to the electrical appliance housing upon actuation of the actuator assembly.

Abstract: A harness assembly for an electrical appliance includes an upper support assembly and a lower support assembly. The upper support assembly includes an upper back pad and at least one shoulder strap emanating from the upper back pad. The upper back pad includes an upper pocket that receives an upper mounting plate of the electrical appliance therein, and an upper flap selectively connectable to the upper pocket to close the upper pocket and retain the upper mounting plate within the upper pocket. The lower support assembly includes a lower back pad and a waist belt emanating from the lower back pad. The lower back pad includes a lower pocket that receives a lower mounting plate of the electrical appliance therein, and a lower flap selectively connectable to the lower pocket to close the lower pocket and retain the lower mounting plate within the lower pocket.
