ABSTRACT:
A vehicle seat has a seat back hingedly connected to a seat cushion. The seat back includes a frame, an actuator and a seat cover. The frame has a support member at a lower lumbar region thereof. The actuator is mounted on the support member. The seat cover envelopes the frame. The seat cover is made of a foam backed material and has a rigid orthotically shaped form. The foam backed material biases the form against the actuator. The actuator is expandable to effect a movement of the form. The form is movable relative to the actuator in response to pressure applied by an occupant of the vehicle seat.
