Micromechanical shock counting device

Abstract

The invention relates to a micromechanical shock counting device (4), comprising: - a frame (41), - an inertial mass (42) adapted to be displaced relative to the frame (41) from a first operating position to a second operating position under the effect of an acceleration experienced by the micromechanical device (4) having a value which exceeds a predefined triggering threshold value, - a drive tooth connected to the inertial mass (43), and adapted to mesh with a counting wheel (3) to drive the counting wheel (3) in rotation by an angular pitch when the inertial mass is displaced from the first operating position to the second operating position, - a suspension structure (43) connecting the inertial mass (42) to the frame (41), the suspension structure (43) being adapted to generate an elastic restoring force (F) tending to return the inertial mass to the first operating position.Figure for the abbreviation: Figure 3.

Claims

transparent to allow an external observer to view the position of the drive tooth (452) relative to the counting wheel (3) through the protective cover (5) or to allow the position of the drive tooth (452) relative to the counting wheel (3) to be read by means of an optical detector.
