Abstract: A chest buckle for a harness for carrying a handheld motor-driven work tool, the chest buckle including first and second parts, wherein the first and second part, each includes at least two mechanisms attaching straps of the harness thereto. The first part includes a recess defining a cavity arranged to accommodate the second part therein. The second part includes a resilient locking member arranged to protrude through a hole in the first part when the second part is accommodated in the cavity to lock the first and second parts together.

Abstract: A carrier assembly for a harness for carrying a handheld motor-driven work tool, the carrier assembly including a back plate having connections for shoulder straps, a hip belt, and a manner for attaching the work tool. The back plate is arranged to be connected to the hip belt by a pivotal connection joint to allow rotation about an axis substantially perpendicular to a plane defined by the back plate.

Abstract: A carrier assembly for a harness for carrying a backpack accessory, the carrier assembly including a back plate including connections for shoulder straps and an interface plate adapted to be attached to the backpack accessory. The back plate includes a coupling interface on a rear face arranged to be removably connected to a corresponding coupling interface on a front face of the interface plate.

Abstract: A carrier assembly for a harness for carrying a motor-driven power tool, the carrier assembly including a back plate and an interface plate including connections for shoulder straps. The back plate includes a coupling interface on a front face arranged to be removably connected to a corresponding coupling interface on a rear face of the interface plate. The coupling interface of the back plate is adapted to be connected to and disconnected from the coupling interface of the interface plate in an at least partially translational or linear movement which is substantially parallel to the back plate.
