Abstract
A side impact crash is sensed from the motion of an edge wall of a vehicle door at a location distal to the door hinge in a direction of swing of the door. The rotation of the door about the hinge responsive to a side impact of the door magnifies the measured motion for a point of impact between the hinge and the sensing location. The motion may comprise acceleration, velocity or a relative motion such as relative velocity. The activation of safety restraint system is responsive to the sensed motion. In another embodiment, a side impact crash is sensed with a magnetic circuit comprising at least one coil and at least one permanent magnet, wherein an axis between the north and south poles of the magnet is substantially perpendicular to an axis about which at least one coil is wound. The relative motion is in a direction substantially perpendicular to the axis about which at least one coil is wound.
