Abstract
A base assembly for a suspension system of a vehicle seat utilizes lower and upper support frame and two pairs of elongated arms which are pivotally connected between the upper and lower support frames to accommodate forward and rearward movement (as well as upward and downward movement) of the upper support frame relative to the lower support frame. The arms act as parallel linkages during the movement of the upper support frame relative to the lower support frame and include broad abutment surfaces which engage one another when the upper support frame is moved forwardly relative to the lower support frame by a prescribed amount to thereby limit the forward movement of the upper support frame relative to the lower support frame. The abutment surfaces are relatively long in length in relation to the overall length of the arms and are bounded by tabs which interlock the arms together at the forward limit of travel of the upper support frame.
