Abstract

Ce couvercle d’obturation (C) d’un trou d’accès à une commande manuelle (13) de pignon (11) d’un boîtier d’accessoires (1) comporte d’un côté des premiers moyens d’interfaçage (21, 31) aptes à coopérer avec un outil externe et de l’autre côté des deuxièmes moyens d’interfaçage (23, 35) aptes à coopérer avec une commande manuelle (13) de pignon (11) de sorte qu’un actionnement du couvercle (C) par l’outil provoque une commande consécutive du pignon (11), et en ce qu’il comporte en outre des moyens de montage réversible du couvercle (C) sur le boîtier (1) dans une première position dans laquelle les deuxièmes moyens d’interfaçage (23, 35) sont situés à l’extérieur du boîtier (1) et une seconde position selon laquelle les deuxièmes moyens d’interfaçage (23, 35) sont en prise avec la commande manuelle (13). Il comporte un moyen (24, 36) de transmission de couple pour transmettre et pour limiter un couple appliqué sur la commande manuelle (13) à l’aide de l’outil. Figure pour l’abrégé : Fig 2B
