Abstract
An adjustable automotive vehicle seat is equipped with a height adjust mechanism that includes a U-shaped frame having laterally spaced side members and a round front cross member that is mounted on the front ends of the side members for rotation about its centerline. A plurality of bow shaped leaf springs are spaced across the width of the seat with their front ends secured to the round front cross member. The rear ends of the leaf springs are secured to a slidable rear cross member. An electrically powered, reversible ball screw actuator translates the rear cross member in the longitudinal direction so that the height of the seat is adjusted by adjusting the curvature of the bow shaped leaf springs.
