Abstract: A linear actuating assembly for a headrest having a fixed portion and a moveable portion configured to support a user's head. The linear actuating assembly comprising a stator fixedly connectable to the fixed portion of the headrest, a rotor circumferentially surrounding the stator, a shaft extending axially through the stator and the rotor, and a nut connected to a threaded portion of the shaft and fixedly connectable to the moveable portion of the headrest. The shaft is fixedly connected to Rotation of the rotor causes linear movement of the nut along the threaded portion of the shaft, thereby moving the moveable portion of the headrest relative to the fixed portion of the headrest.
