- Alarm device. - The alarm device comprises: . at least one accelerometer (6) having an axis of sensitivity (x'- x'') arranged substantially parallel to a reference plane (P) linked to the body and supplying a variation in an electric quantity which is an image of the variation in the stable position of the body and detecting the modification in the stable position of the body, . a converter (13) of the variation in the electric quantity into a proportional voltage, . an amplification and filtering stage (14), . and a threshold-excess comparison circuit (15). - Application to alarm devices for motor vehicles. <IMAGE> |
