ABSTRACT:
A height adjustment mechanism for a vehicle seat cushion which permits selective vertical adjustments of the forward and the rearward portions of the seat. The seat support includes fore and aft brackets which extend downward from the seat cushion and are attached in a pivotal manner at their lower ends to outboard ends of link arms. The link arms extend in the fore and aft direction from a central location where they are pivoted about a common axis and supported by a stationary support or bracket means. Interaction between pins carried by the arms and vertically toothed sector means formed in the stationary bracket positively locates the arms in a preselected vertical position. The arms are movable within a range determined by the extent which the pins are free to move in the toothed sector or slotted apertures. A centrally located actuating rod extends coaxially with respect to the torque rods and includes a cam portion near its end which produces selective unlatching movement of the pins away from the toothed sector of the elongated slots. Thereafter, the link arms can be rotated to change the height orientation of either the forward or the rearward edge of the seat cushion.
