  • TRAILER JACK-KNIFE PREVENTION SAFETY DEVICE
    Publication number: 20190100261
    Abstract: A trailer jack-knife prevention safety device automatically deploys over a threshold speed to physically inhibit jack-knifing of a trailer. The device includes an actuator coupled to a trailer. A trailer speed sensor is operationally coupled to the actuator for detecting a speed of the trailer. The trailer speed sensor activating the actuator to extend a pin when the trailer is traveling faster than a threshold speed and deactivates the actuator wherein the pin is retracted when the trailer is traveling slower than the threshold speed. When extended, the pin limits pivoting of the trailer relative to the vehicle to inhibit jack-knifing of the trailer.
