This avoids that, for example, after a rotation of the key by about 90 °, the first tumbler is received by the second locking channel and at the same time the second tumbler is received by the first locking channel, so that the key could be removed in this position from the locking system , In this way, it can be prevented, in particular, that in the case of an ignition lock of a motor vehicle, the key can be removed from the locking system used for the ignition lock while the engine is running. Instead, it is ensured that the key must be turned back to the 0 ° position or, if necessary, to a 180 ° position before the key can be removed again.

Abstract

Le boîtier du cylindre de fermeture (26) présente un premier canal de verrouillage (34) pour le logement de la première gâchette (18), et un second canal de verrouillage (36) pour le logement de la seconde gâchette (20). Conformément à l'invention, une largeur (a) de la première gâchette (18), perpendiculairement à la direction de déplacement radiale, est supérieure à une largeur d'ouverture (b) du second canal de verrouillage (36), perpendiculairement à la direction de déplacement radiale. De ce fait, la première gâchette (18) ne peut pas coulisser à l'intérieur du second canal de verrouillage (34), de sorte qu'on ne peut retirer involontairement la clé (10) du système de fermeture (24) en une position non souhaitée.
