Charnière (D, D?1¿, D?2¿, D?3¿, D?4¿) destinée à rendre élastique une branche (A, A?1¿, A?2¿, A?3¿, A?4¿) par rapport à l'embout (3, 3?1¿, 3?2¿, 3?3¿, 3?4¿) respectif de la monture (F) d'une paire de lunettes. La charnière (D, D?1¿, D?2¿, D?3¿, D?4¿) comporte au moins un élément d'articulation mâle (100, 100?1¿, 100?2¿, 100?3¿, 100?4¿) relié à pivotement à au moins un élément femelle correspondant (200, 200?1¿, 200?2¿, 200?3¿, 200?4¿). L'élément d'articulation mâle (100, 100?1¿, 100?2¿, 100?3¿, 100?4¿) comporte au moins un élément de liaison (12, 12?1¿, 12?2¿, 12?3¿, 12?4¿) apte à coulisser par rapport à la branche (A, A?1¿, A?2¿, A?3¿, A?4¿), une douille (2, 2?2¿, 2?3¿, 2?4¿, 73) disposée à l'intérieur de la branche (A, A?1¿, A?2¿, A?3¿, A?4¿) et associée axialement à l'élément de liaison (12, 12?1¿, 12?2¿, 12?3¿, 12?4¿), et un moyen élastique (5, 5?1¿, 5?2¿, 5?3¿, 5?4¿) tendu entre la douille (2, 2?2¿, 2?3¿, 2?4¿, 73) et un élément formant butée (6, 6?1¿, 6?2¿, 6?3¿, 6?4¿) solidaire de l'élément de liaison (12, 12?1¿, 12?2¿, 12?3¿, 12?4¿).
