ABSTRACT:
This invention includes crash sensors designed to be used for side impact sensing and the strategies of using these sensors. If is analyzed and shown that velocity sensing or damped sensors are desirable for side impact sensing. Inertially damped sensors, with a damping force proportional to the square of velocity, is most appropriate. Such sensor can be made of plastic and in the shape of short round or rectangular cylinders. It is further concluded that these sensors should be installed on the side door structure of a vehicle. Other sensing strategies include installing sensors on three locations: one at the center of the side door, one just before the A-pillar, and one just after the B-pillar; and Safing (arming) sensors for side impact applications could be crush sensing switches.
