Apparatus for checking the validity of the fall determination

(57) Abstract: To perform a simple and validity checks possible a reliable fall determination (e1), a predetermined lower limit or acceleration measured in the vertical direction of the vehicle (az) exceeds a predetermined upper limit threshold value below the threshold value, or has been measured in the vertical axis direction acceleration (az) is between the both threshold, the horizontal axis direction on the measured acceleration of the vehicle (ay) at the same time was measured in the vertical direction below the threshold value (ays) which depends on the acceleration (az), provided with means (SE) for signaling the validity of fall determination (e1).
