Propeller blade pivot

A pivot for a blade of a propeller, the pivot comprising:

• a proximal portion suitable for being retained in a radial orifice in a propeller hub while being capable of turning in the orifice about a longitudinal axis of the pivot;
• and
• a distal portion including at least one arm extending laterally relative to said longitudinal axis and supporting a flyweight at an end of said at least one arm furthest from said longitudinal axis;
• wherein at least said proximal portion is made of metal, at least said at least one arm is made of organic matrix composite material, and a receptacle for retaining a blade root is formed in a metal extension of the proximal portion of the pivot that passes through the distal portion of the pivot and presents a longitudinal section that diverges towards a distal end of the pivot to retain along the longitudinal axis, by interlocking shapes, the distal portion of the pivot.
