Abstract
A motor-vehicle headrest has a head part and a base part, the latter being surrounded by and shiftable on the head part in a predetermined direction. A pair of inner racks on the base part are directed oppositely outward toward the head part and each have an array extending in the direction of gear teeth. Similarly, a pair of outer racks on the base part are directed toward each other inward, confront the inner racks, and are formed with respective arrays extending in the direction of gear teeth. Respective gears each mesh with a respective one of the outer racks and the respective inner rack so that on movement between the inner and outer positions the gears roll between the respective racks. A play compensator between one of the racks and the respective part biases the racks and gears into tight engagement with one another.
