ABSTRACT:
Anti-jackknifing apparatus for combination with conventional tractor-drawn trailers wherein the tractor includes a forwardly disposed operator's cab and a rearwardly disposed fifth wheel assembly having a skid-plate. The skid-plate conventionally includes a pair of longitudinally rearwardly extending guide-lugs having therebetween a V-slot horizontally converging toward an upright kingpin or other pivotal association with the trailer. The anti-jackknifing apparatus comprises a generally horizontal longitudinally extending restraining-tongue terminating as a forward head-part, which head-part has an inactive normal-station and also an anti-jackknifing extended-station respectively located remote from and abuttably within the skid-plate V-slot during a potentially jackknifing panic situation. The restraining-tongue head-part is actuatably reciprocated between normal-station and extended-station and remotely controlled from the tractor operator's cab during a potentially jackknifing panic situation, and especially at extended-station the restraining-tongue is stationarily rigidly associated with the trailer underside.
