A novel nose pad assembly (16) for eyeglasses (10) is provided wherein the support (36) and nose pad (38) are formed as a fully articulating ball and socket joint. The ball and socket joint provides excellent adjustability of the nose pads (38) in a simple mechanical construction. In a unique method of forming the nose pad assembly (16) the support structure (ball) (42) is formed in a first molding step and an adjustable pad member (38) is molded directly over the bass (42) of the support structure (36) in a second molding step. The present invention utilized in-mold-assembly techniques to reduce the assembly steps required to form such a nose pad assembly (16) while further resulting in a nose pad that has increased adjustability and utility. Alternately, the pad portion (38) may be formed first and the support structure (36) formed second. Also, the materials selected may include either hard or soft plastics to form either component.

Cet assemblage (16) novateur de plaquettes pour lunettes (10) comprend un support (36) et une plaquette (38) qui forment ensemble un joint à bille. Le joint à bille assure une ajustabilité excellente des plaquettes (38) avec une structure mécanique simple. Selon une méthode unique de formation de l'assemblage (16) de plaquettes, on forme la structure de support (bille) (42) pendant une première étape de moulage et on façonne par moulage un élément de plaquette ajustable (38) directement sur la bille (42) de la structure de support (36) pendant une deuxième étape de moulage. L'invention utilise des techniques d'assemblage dans le moule pour réduire le nombre d'étapes d'assemblage requises pour former l'assemblage (16) de plaquette, tout en permettant d'obtenir une plaquette à ajustabilité et utilité améliorées. Alternativement, on peut former d'abord la partie plaquette (38), puis la structure de support (36). En outre, les matériaux sélectionnés pour former chaque composant peuvent être des matières plastiques dures ou souples.
