Abstract

L'invention concerne un dispositif d'actionnement pour un véhicule comprenant une platine (4 ; 14 ; 24) sur laquelle est disposé un élément de commutation actionné par force (5a, 5b; 16; 26a, 26b). La platine (4 ; 14 ; 24) est supportée dans un logement (1 ; 11 ; 20) et un recouvrement de protection flexible (7) est disposé à côté de l'élément de commutation actionné par force (5a, 5b; 16; 26a, 26b), lequel permet d'actionner l'élément de commutation (5a, 5b; 16; 26a, 26b) par déformation du recouvrement de protection (7). Le logement (1 ; 11 ; 20) présente une première partie (3 ; 23) ayant une première élasticité qui est accouplée à une partie supplémentaire (2 ; 15) ayant une deuxième élasticité inférieure. La platine (4 ; 14 ; 24) est retenue dans la première partie (3 ; 23) dans une position de repos et lors d'une application de force sur l'élément de commutation (5a, 5b; 16; 26a, 26b) s'écarte en déformant la première partie (3 ; 23) dans la direction de l'application de la force. La force de rappel, agissant sur la platine (4 ; 14 ; 24), de la première partie (3 ; 23) par rapport à la partie supplémentaire, lors de déviations depuis la position de repos de la platine, est inférieure à une force d'actionnement maximale admissible de l'élément de commutation.
