<p>M. O Heesch-4 VEHICLE SEAT ADJUSTMENT APPARATUS An apparatus for selectively positioning an automotive vehicle seat as powered by an electric motor drive. The motor drive output is transmitted to operate individual lead screws for the horizontal and vertical seat movements. The horizontal drive is effected within track members at the lateral sides of the apparatus. To provide vertical movement of the front and rear ends of the seat, separate mechanisms from the motor drive to front and rear end lead screws are provided, these mechanisms being spaced apart laterally within the area defined by the track members. These vertical drive lead screws cause rotation of respective individual torsion bars at the respective front and rear ends of the seat. By the construction shown, rotation of a torsion bar rotates a link to raise or lower the respective seat end accordingly.</p> |
