• an intermediate knuckle (40) connected to each of said fixed and moving knuckles (20;
• 30) by a respective hinge pin (11;
• 15) placed in a respective bushing (12;
• 16) secured to the respective one of said fixed and moving knuckles, each said bushing having a flat (13;
• 17) on an outer face thereof,
• an immobilizing member (50) collaborating alternately with one of said flats (13;
• 17) of said bushings (12;
• 16) to successively allow said moving knuckle (30) to pivot about the respective said hinge pin (15), then allow said intermediate knuckle (40) and said moving knuckle (30) to pivot about the respective said hinge pin (11) of said fixed knuckle (20) as the rear door (2) is opened and, conversely, as the rear door is closed,
• wherein said intermediate knuckle (40) comprises a plate (41) and two parallel cheeks (42, 43) perpendicular to said plate (41), and said immobilizing member (50) comprises a link rod (51) held in position by one of said cheeks of said intermediate knuckle (40) and said bushings (12;
• 16), said link rod (51) being moveable in a sliding manner as the respective said bushing (16) of the respective said hinge pin (15) of said moving knuckle (30) rotates between two positions in contact with said flat (13;
• 17) of each said bushing (12;
• 16), and
• wherein said link rod (51) comprises, at each of its ends, a fork (52, 53) for positioning on the respective said bushing (12;
