Abstract
A motor energizing control and reversing circuit designed to be used on a power seat control in vehicles. The circuit includes a reversible motor that primarily drives suitable gear trains which effect seat movement in a plurality of directions and then momentarily reverses the motor so as to apply moving power to the gear train in an opposite direction to relieve pressure thereon and prevent a locked rotor condition in which the seat could not be moved.
