Abstract
An apparatus for selectively positioning an automotive vehicle seat is disclosed. The apparatus is adapted to be powered by an electric motor drive, such as a motor with multiple armatures or by using separate motors or by using clutch activated members driven by a single motor. Output of the motor drive is transmitted through respective gearing to lead screws within tracking structures at both sides of the seat to translate the seat horizontally. The motor drive output is also transmitted to operate individual lead screws for the vertical seat movements. To provide elevational 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 distributed along the seat width. These 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 raises or lowers the respective seat end.
