Abstract
Une paire de lunettes est composée dune monture avec verres et branches. Chacune des branches comprend un premier membre ayant des extrémités proximale et distale, lextrémité proximale étant montée de manière pivotante sur la monture autour d'un premier axe de telle façon que le premier membre est mobile entre une position ouverte et une position fermée. L'extrémité distale comprend une première partie faite en un premier matériau. Chacune des branches comprend en outre un second membre qui s'étend le long d'un deuxième axe depuis lextrémité proximale vers lextrémité distale, le second axe croisant le premier axe, lextrémité proximale du second membre comprenant une deuxième partie faite en un deuxième matériau. En outre, l'une des première et seconde parties est surmoulée sur l'autre des première et seconde parties pour fixer ensemble les première et deuxième parties. De plus, le second matériau est différent du premier matériau et incompatible avec celui-ci, de telle sorte que le second membre peut pivoter par rapport au premier membre autour d'un troisième axe croisant le deuxième axe.
