ABSTRACT:
An impact sensing device including an inertia member, an housing for accommodating the inertia member therein and at least three impact sensors disposed in such a manner as to be in contact with an outer peripheral surface of the inertia member, each impact sensor comprising a piezoelectric element for generating a voltage having an amplitude corresponding to an applied stress and an urging member for urging the piezoelectric sensor against the inertia member. Upon application of an impact force to the impact sensor, the inertia member presses the piezoelectric element with a stress corresponding to the impact force to thereby allow the piezoelectric element to generate a voltage corresponding to the applied stress.
