Abstract: A vehicle power seat adjuster control system that provides for the pulsed reversal of rotation of the armature of the operating motor of a vehicle power seat adjuster mechanism each time the operating motor is deenergized at the conclusion of each seat adjusting operation.

Abstract: A controlled bi-directional electric motor is energized for armature rotation in respective opposite directions in response to the operation of an electrical control switching arrangement electrically open and electrically closed. A mechanically operable electrical switching device arranged to be operated by a mechanical movable member that is driven between first and second travel limits by the controlled motor is effective, when the movable member is driven by the motor to either travel limit, to interrupt motor energization and to condition the circuit for effecting motor energization for armature rotation in the direction to drive the movable member toward the other travel limit.

Abstract: A controlled bi-directional motor is energized through a power switching arrangement of the type electrically operable in a manner to energize the motor for rotation in one direction and in another manner to energize the motor for rotation in the opposite direction. Circuitry including a single pole-single throw electrical switching device is responsive to the operation of the switching device electrically open to operate the power switching arrangment in the manner to energize the motor for rotation in a first direction and other circuitry also including the electrical switching device is responsive to the operation of the electrical switching device electrically closed to operate the power switching arrangment in the manner to energize the motor for rotation in the opposite direction.
