ABSTRACT:
An apparatus for measuring the acceleration of the head or thoracic regions of an anthropomorphic dummy used in auto crash testing which is characterized by a mounting arrangement which provides redundant data capability meeting the required government regulations. Three pairs of acceleometers are mounted within test site cavities provided in the crash dummy within the strict government standards to provide two sets of three accelerometers instead of one. Each accelerometer of each pair is accomodated within a mounting structure relative to required standard reference planes and within a supecified location relative to their sensitive axes such that the data obtained therefrom may be used to obtain acceptable redundant force signals for purposes of the crash test.
