Abstract

L'invention se rapporte à un dispositif de verrouillage/déverrouillage 1 d'une pièce mobile 2 relativement à une pièce fixe 3. Ce dispositif 1 comprend un verrou 11 et un élément d'appui 12. Le verrou 11 comporte un doigt de verrouillage 111 et un élément de déclenchement 112. Dans une configuration de verrouillage, le doigt 111 coopère avec l'élément d'appui 12 de manière à maintenir la pièce mobile 2 dans une position de fermeture. Dans une configuration de déverrouillage, le doigt 111 et l'élément de déclenchement 112 sont désenclenchés, permettant un déplacement de la pièce mobile 2 relativement à la pièce fixe 3. La structure du verrou 11 est telle que le déverrouillage du dispositif 1 fait passer le doigt 111 par une position angulaire dans laquelle celui-ci écrase l'élément d'appui 12 jusqu'à désenclenchement du doigt 111 et de l'élément de déclenchement 112. Pour permettre un tel déverrouillage tout en assurant un maintien satisfaisant en configuration de verrouillage, l'élément d'appui possède des propriétés élastiques.The invention relates to a locking / unlocking device 1 of a moving part 2 relative to a fixed part 3. This device 1 comprises a latch 11 and a support element 12. The latch 11 comprises a locking finger 111 and a trigger element 112. In a locking configuration, the finger 111 cooperates with the support element 12 so as to maintain the movable part 2 in a closed position. In an unlocking configuration, the finger 111 and the trigger element 112 are disengaged, allowing movement of the movable part 2 relative to the fixed part 3. The structure of the lock 11 is such that the unlocking of the device 1 passes the finger 111 by an angular position in which the latter crushes the support element 12 until the finger 111 and the trigger element 112 release. To allow such unlocking while ensuring satisfactory maintenance in the locking configuration , the support element has elastic properties.
