Abstract

L'invention porte sur un boîtier mou comprenant une plaque de base (15), plusieurs tiges de tension (12), un couvercle réfléchissant de type parapluie (16), un diffuseur (17) et une intercouche (11) fixée entre la plaque de base et le diffuseur. Un élément de localisation est disposé au niveau de la tige de tension. Le coin de l'intercouche est relié à l'élément de localisation. L'intercouche ayant une élasticité spéciale comprend une section de matériau inélastique (25) à travers l'intercouche le long du plan de l'intercouche. Le matériau élastique (24) au coin de l'intercouche peut maintenir l'intercouche lisse après que le couvercle réfléchissant de type parapluie est complètement installé.
