Abstract
A device (20) for folding a blade (5), the device comprising a fitting (30) and a cuff (50) connected to said fitting (30). The fitting (30) has at least one horizontal pin axis (31) perpendicular to a radial direction (AX2) and a clevis (35) axially offset relative to the horizontal pin axis (31) in the radial direction (AX2). The cuff (50) has an insert (51) inserted in said clevis (35), a vertical pin (70) passing through said clevis (35) and said insert (51). The cuff (50) includes at least one horizontal fastener pin axis (55) axially offset relative to said insert (51) along the radial direction (AX2), at least one lateral arm (80) connects said horizontal pin axis (31) to said fastener pin axis (55).
