Abstract
Apparatus for sensing and recording changes in the velocity of a vehicle involved in a crash comprises a sensing mass biased to an initial position in which it remains until it is acted upon by an acceleration pulse of such magnitude as to overcome the biasing force, whereupon the mass moves from its initial position a distance proportional to the magnitude and duration of such pulse. If the magnitude and duration of the pulse are less than preselected values, decay of the pulse enables the biasing force to return the mass to its initial position. If the magnitude and duration of the pulse are greater than such preselected values, however, retaining means act on the mass to retain the latter in its position of maximum movement from its initial position, thereby providing an indication of the velocity change. Preferably, indicia is associated with a sensing means to facilitate determination of the velocity change.
