Zusammenfassung:	Disclosed is a compact vibration isolation system (120) for mounting an inertial sensor assembly (ISA) (122) to an Inertial Measurement Unit (IMU) housing (136). The housing (136) is mounted to a support (155) that is subjected to shock and vibration. The vibration isolator assembly (120) includes a ring shaped elastomeric member (126) laminated between a ring shaped inner member (130) and a ring shaped outer member (128). The inner member (130) is securely mounted to the ISA (122), and the outer member (128) is mounted to a support (137) of the IMU housing (136). Because of the compact size of this system (120), the IMU housing (136) contains and protects the elastomeric member (126) from potential contamination and damage, as well as eliminates the need for delicate mechanical and electrical interfaces. The elastomeric member (126) of the system (120) isolates the ISA (122) from shock, vibration, and acoustic energy that may otherwise be transmitted from the support (155) to the ISA (122). La présente invention concerne un système compact anti-vibrations (120) qui permet d'installer un ensemble détecteur inertiel (EDI) (122) sur un boîtier (136) d'unité de mesure par inertie (UMI). Le boîtier (136) est monté sur un support (155) qui est soumis aux chocs et aux vibrations. L'ensemble anti-vibrations (120) comprend un élément élastomère (126) de forme annulaire qui est intercalé entre des éléments interne (130) et externe (128) de forme annulaire. L'élément interne (130) est solidement fixé sur le EDI (122) et l'élément externe (128) est monté sur un support (137) du boîtier (136) de l'unité UMI. Du fait de la taille compacte de ce système (120), le boîtier (136) de l'unité UMI renferme l'élément élastomère (126) et le protège de la contamination et des dommages potentiels et, de surcroît, évite de devoir utiliser des interfaces mécaniques et électriques fragiles. L'élément élastomère (126) du système (120) isole le EDI (122) des chocs, des vibrations et de l'énergie acoustique qui, en son absence, seraient transmis du support (155) à l'ensemble EDI (122).
