Abstract

An acceleration threshold sensor includes a supporting device, a seismic mass, and a connecting device with the aid of which the seismic mass is attached to the supporting device. The connecting device is provided with a predetermined breaking point interrupting the connection between the seismic mass and the supporting device when said seismic mass is subjected to an acceleration exceeding a predetermined acceleration. This sensor has a simple structural design, can be produced at a reasonable price and is always ready to carry out a measurement. Additionally, this sensor is able to store, without any auxiliary power, that it has been subjected to an acceleration exceeding a predetermined acceleration.
