Abstract
A shock absorbing apparatus suitable for use on a load carrying vehicle at the rear and/or front thereof comprises an arm pivotable to the frame or chassis of the vehicle close to the end thereof and extending downwardly to support on its lower end a horizontally disposed bumper bar extending across the vehicle, a shock absorbing device pivoted to the arm between said pivot and the bar and pivoted to the vehicle frame or chassis at a point spaced along the vehicle from said arm pivot, said three pivots forming the three apices of a triangle, lost motion means associated with at least one of said pivots to vary the configuration of said triangle to permit the arm to swing upwardly away from the vehicle frame or chassis to clear ground height variations in the path of the bar, and means to restore the arm to its normal position when the bar is clear of such ground variations.
