ABSTRACT:
A device for forwardly and backwardly adjusting a head-rest according to the invention comprises a base plate fixed to stays extending above a back of a seat for an automobile and provided at its ends with lower rails formed with anchoring apertures, a slide formed on its upper surface with guides and on both sides with upper rails to be fitted with the lower rails, a flat plate-like locking lever traversely slidable within the guide of the slide and having a pair of anchoring pieces extending downwardly to engage in the anchoring apertures of the lower rails, a spring for urging the locking lever in one direction, and a cover for covering the base plate and the slide. With this arrangement, the position of the head-rest can be slidably adjusted by pushing the locking lever against the resilient force of the spring, and the head-rest can then be fixed at a desired position by releasing the locking lever.
