Claim 0:
1. A powered paragliding harness comprising a harness (1) including a back rest (7) for the pilot's back and an engine mount (10) carrying a power unit (2) including a propeller (3),
wherein the back rest (7) and the engine mount (10) are connected via a lever mechanism (4),
wherein the lever mechanism (4) comprises at least a first lever (8) and a second lever (9), each lever (8,9) being connected with one end to the back rest (7) via a hinged connection and with the other end to the engine mount (10) via a hinged connection,
wherein the lever mechanism (4) uses a three-bar linkage mechanism,
wherein the first lever (8) is shorter than the second lever (9),
wherein in the operational status of the harness (1) the first lever (8) is situated above the second lever (9),
wherein the levers (8, 9) are arranged to enable the transition from an upright position (5), where the angle between back rest (7) and propeller (3) is small, especially back rest (7) and propeller (3) are parallel or close to parallel, to allow for an upright position of the pilot during take-off and landing, into a reclined position (6), where the angle between back rest (7) and propeller (3) is larger than in the upright position (5), to allow for a reclined position of the pilot during flight, and vice versa, and
wherein the connection between second lever (9) and engine mount (10) is situated nearer to the center of gravity (12) of the power unit (2) than the connection between first lever (8) and engine mount (10).
