Abstract
A four-way power lumbar support system which provides for both an in-out directional adjustment and an up-down directional adjustment including a pair of directional one-way locking clutches that slip in one direction and lock in another direction, a single motor, and a single gearbox assembly. The motor output drives the two directional one-way locking clutches setup to slip and lock in opposite directions of rotation causing one to engage for clockwise rotation of the motor and the other to engage for counterclockwise rotation of the motor.
