Patent ID: 7731216

Claim:
An apparatus which attaches to a commercial truck, said commercial truck being composed of a tractor portion and a trailer portion attached by a fifth wheel plate, which said apparatus automatically detaches the tractor from the trailer in the event of a trailer induced weight shift rollover, allowing the tractor to remain upright and in tact, said apparatus comprising: at least two weight-bearing supports equidistant from the fifth wheel plate located on said tractor, each of said weight-bearing supports containing a pneumatic quick release cylinder mounted inside a longitudinal axis of said weight-bearing supports, wherein said pneumatic quick release cylinder being activated through air that has been compressed and stored in an air tank, thereby creating an air flow supply; at least one quick release pin that attach said weight-bearing supports to said fifth wheel plate; at least two air flow supply lines connected to each of said pneumatic quick release cylinders; an air actuator connected through an electrical means to said airflow supply lines and said weight-bearing supports; at least two sensors connected through said electrical means to said air actuator, said sensors positioned on opposite sides of said tractor's frame; a tilt switch connected through said electrical means to said sensors and said air actuator located behind the cab of said tractor, said tilt switch sensing when said tractor is 15 degrees from the ground, said tilt switch activating said electrical means when 15 degrees from the ground has been sensed, said sensors then changing an air flow in said actuator from a forward push to a reverse push when said tilt switch measures a 30 degree angle between said tractor and the ground, thereby causing said pneumatic quick release cylinders and said quick release pins to release from said fifth wheel, thereby breaking apart said trailer from said tractor.
