Abstract
A vehicle head restraint on a seat back is adjustable in height from a non-usage position to a usage position. The head restraint is disposed on a retaining element formed from a U-shaped tubular section and of which a horizontally disposed section forms the axis of rotation of the head restraint. The head restraint and retaining element are coupled by means of a spring element such that a biasing force of the spring element is applied to the head rest, wherein sections of the spring element engage in respective cutouts disposed on both sides in the region of rounded portions of the retaining element, and the biasing force generated rotates a lower end of the head rest automatically in the direction of the retaining element as the head rest is moved from the non-usage position to the usage position.
