A seat assembly comprises a seat cushion and a seat back having a bottom portion coupled to the seat cushion and an opposite top portion. A head restraint is coupled to the seat back for movement between a stowed position adjacent the top portion of the seat back and a deployed position spaced above the top portion of the seat back. A cable carriage is coupled to the seat back for actuation along a longitudinal axis between a home position and a lift position. A cable extends between a first end coupled to the head restraint and a second end coupled to the cable carriage for moving the head restraint between the stowed position and the deployed position in response to actuation of the cable carriage between the home position and the lift position.
