Abstract

L’invention concerne un dispositif micromécanique de détection de choc (2), comprenant :- un cadre (4),- une masse inertielle (5) montée mobile par rapport au cadre (4),- un indicateur (6) monté mobile par rapport au cadre (4),- une structure de liaison (7) reliant l’indicateur (6) à la masse inertielle (5) et au cadre (4), la structure de liaison (7) étant configurée de telle sorte qu’un déplacement de la masse inertielle (5) depuis une première position initiale jusqu’à une première position finale entraine un déplacement corrélatif de l’indicateur (6) depuis une deuxième position initiale jusqu’à une deuxième position finale,- une structure de verrouillage (8) configurée de sorte qu’une fois en position verrouillée, la structure de verrouillage (8) empêche un retour de la masse inertielle (5) vers la première position initiale, ce qui a pour effet de maintenir l’indicateur (6) dans la deuxième position finale.
