Abstract
A trailer hitch assembly for connecting a towing vehicle to a towed trailer having symmetrical anti-sway features. The assembly includes a hitch ball rigidly affixed to a hitch beam extending transversely from the rear of the towing vehicle. A pair of spring-biased telescopic compressible and extendable control rods are connected to each end of the hitch beam and at their other ends to a control beam. A hitch bar is connected to the hitch ball on the towing vehicle and pivotally connected to the forward end of a trailer coupler that intersects and is pivotally connected to the central portion of the control beam by a pivot member. The pivot member is integral with the control beam and includes a control arm having a roller engaged with a downwardly opening slotted rearward end of the hitch bar. The trailer coupler includes a trailer hitch ball to which a trailer coupler socket is connected, with the trailer coupler socket being rigidly affixed to the tongue or frame of the towed vehicle.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
