A thermoplastic air bag cover (10) is provided having a plurality of domes (20) formed on its front cover (12) which enclose switches (32) of at least one multifunctional unitary switching module (22). Preferably, a pair of unitary multifunctional switching modules (22''', 46''') are provided and corresponding raised domes (44) in the front cover (12) sealingly enclose and protect the switches (32) thereof and also serve as switch activation mechanism. In a separate embodiment of the invention, a coupling mechanism (56''') is provided for both mechanically and electrically coupling the first and second unitary switching modules (22''', 46''') together in order to faciliate assembly of the resulting air bag cover (10''').
Cette invention concerne un couvercle thermoplastique (10) de coussin pneumatique de sécurité ayant un ensemble de dômes (20) intégrés à sa partie frontale (12) qui renferment des commutateurs (32) faisant partie d'au moins un module (22) monobloc multifonctionnel de commutation. De préférence, deux modules (22''', 46''') monoblocs multifonctionnels de commutation sont intégrés au couvercle et chaque dôme (44) bombé correspondant de la partie frontale (12) du couvercle forme un capot d'étanchéité protégeant les commutateurs (32) qui y sont enfermés, chacun de ces dômes servant de mécanisme d'activation des commutateurs. Dans une réalisation séparée de l'invention, un mécanisme de couplage (56''') permet le couplage mutuel mécanique et électrique du premier et du second modules (22''', 46''') monoblocs, ce qui facilite l'assemblage du couvercle (10) de coussin pneumatique de sécurité ainsi constitué.
