Abstract

A headrest for a vehicle seat has a head support and a mounting assembly carrying the head support on a vehicle seat and comprising a four-pivot linkage having an upper holding element on the head support and a lower holding element fixed to the seat. First and second links interconnect the upper holding element at respective first and second upper pivots on the upper holding element and the lower holding element at respective first and second lower pivots on the lower holding element. Thus the four-pivot linkage can shift the head support relative to the vehicle seat between a front position moved forward toward the head of a seat occupant, and a rear position moved backward therefrom. The upper are at a different relative horizontal spacing on the upper holding element than the lower pivots on the lower holding element.
