1. A system to sense an automotive imbalance and to cut-off the power to the ignition in response thereto for increased safety in the event of an accident comprising, in combination:

  • automotive imbalance sensors positionable adjacent the front wheels and rear wheels of a vehicle, each sensor comprising an upper attachment member attachable to an upper portion of a shock absorber and a lower attachment member attachable to a lower portion of a shock absorber, a vertically extending rod fixedly secured with respect to the lower attachment member and slidably secured with respect to the upper attachment member, a roller secured to the upper attachment member with the roller adapted to rotate with respect to the rod during normal reciprocation thereof during driving but to shift laterally with respect to its axis during abnormal extended movement of the rod as caused by an emergency situation, a switch secured to the upper attachment member in a closed orientation during normal reciprocation of the rod but adapted to switch to the closed orientation upon the shifting of the roller in response to an abnormal movement of the rod; and

    a controller to detect when two adjacent wheels, two front wheels, two rear wheels, two left wheels, two right wheels, experience an abnormal condition resulting in abnormally extended movement of their associated rods with detection signals from their associated switches and, in response thereto, generates an emergency signal to energize a power cut-off member to stop the power to the ignition system and cut-off the flow of fuel within the vehicle.
