ABSTRACT:
This invention includes crash sensors designed to be used for frontal impact sensing and the strategies of using these sensors. It is analyzed and shown that velocity sensing or damped sensors are desirable for frontal impact sensing. Inertially damped sensors, with a damping force proportional to the square to velocity, is most appropriate. Such sensors can be made of plastic and in the shape of short round or rectangular cylinders. The particular shape the these sensors minimizes the chance that the sensors will be rotated during the crash. It is further concluded that these sensors should be installed on the frontal radiator structure or at such similar location near the front of the vehicle. A typical crash sensor includes a hinged plastic mass attached to the housing. The mass activates a contact assembly after a predetermined movement of the mass. The gap existing between the movable mass and the interior wall of the housing enhances the damping function of the crash sensor.
