Abstract
L'invention porte sur un couvercle thermoplastique (10) relativement souple pour coussin gonflable de sécurité comportant un panneau frontal (12) muni de plusieurs éléments d'actionnement d'un interrupteur améliorant l'activation d'un interrupteur à membrane (24) placé dans un logement (20) pratiqué dans le panneau frontal. Cette caractéristique offre plusieurs points de pression qui améliorent l'actionnement de l'interrupteur à membrane. Dans une variante, les éléments (32) actionnant l'interrupteur sont placés sur la surface intérieure arrière (16) du couvercle, et, dans une autre variante, ils sont placés sur la surface supérieure d'une plaque arrière (26) présentant un compartiment creux pour l'interrupteur. Les éléments (32) d'actionnement de l'interrupteur peuvent prendre la forme de petits cercles, de nervures, de points, de X etc. faisant partie intégrante du couvercle.
