A headrest intended for mounting on the ceiling or roof of a vehicle above the head of an occupant of the vehicle who is sitting in a vehicle seat, the headrest mounted for vertical adjustment by a telescoping shaft so that the head rest lies directly behind the occupant's head, with the headrest being swingably movable forwardly or rearwardly with respect to the occupant along an arcuate path relative to the vehicle ceiling, this forward and rearward movement effected by a reversable electric motor mounted in the ceiling and having a gear driven thereby and engaging an arcuate segment gear attached to the top end of the telescopic shaft, the headrest thus being swingable forwardly or rearwardly relative to the occupant of the vehicle as well as being vertically adjustable such that the headrest may be properly adjusted to lie directly behind the occupant's head in the most comfortable and safe position for use. In addition, when the headrests are not in use they may be readily moved to a position not affecting any possible lines of vision of the vehicle driver.
