Abstract: M. O Heesch-4 VEHICLE SEAT ADJUSTMENT APPARATUS     ABSTRACT OF THE DISCLOSURE: 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.

Abstract: ABSTRACT Field Effect Transistor (FET) integrated circuits can be deleteriously affected by positive voltages without compensating negative voltages. This problem can be overcome by providing a sequencing circuit which prevents the application of positive voltages without compensating negative voltages.  This can be accomplished by providing one electronic switch in the positive lead and connecting a second electronic switch to the control electrode of the first switch.  The second switch is only conductive when the negative voltage is available and the first switch can only be conductive when the second switch is conductive.  A delay circuit ensures that the second switch is conductive only after the negative voltage is applied to the load and a charge storage device ensures that negative potential is applied to the load after removal of the negative power source to ensure removal of positive potential to the load before the negative potential is removed.
