ABSTRACT:
A collision detecting device for a motor vehicle includes a base plate coupled within an open end of a bottomed cylindrical case and secured in place to provide a sealed chamber, a support shaft rotatably mounted within the sealed chamber, a rotary member provided on the support shaft for rotation therewith and having the center of gravity positioned eccentrically from its rotational axis, a pair of contact elements provided on the rotary member for rotation therewith and being symmetrically arranged with respect to the rotational axis of the rotary member, a pair of electric terminals fixed to the base plate, the terminals each having an internal contact portion slidably engageable with each of the contact elements and an external terminal pin for connection to an electric control circuit, and a spring disposed within the sealed chamber to apply a counteracting rotational force to the rotary member depending on an angle of rotation through which the rotary member has rotated.
