Abstract
A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar having a modulus of elasticity, the moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a releasable tension member comprising a top portion configured to be pivotally supported by a frame member of the trailer and configured to pivot about a horizontal axis, and a bottom portion configured to support the rearward end of the moment bar; and a moment bar preload mechanism configured to push up the moment bar rearward end to thereby preload the moment bar; wherein, when the moment bar rearward end has been preloaded, the releasable tension member can be pivoted between a first angular position and a second angular position below the preloaded moment bar; wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle is disclosed.
