Abstract

A motor-vehicle headrest has a base fixable to a motor vehicle seat and a cushion support having a forwardly directed front face adapted to engage a head of a person in the seat. An upper link has a front end pivoted at an upper support axis on the support and a rear end pivoted at an upper base axis on the base, and a lower link having a front end pivoted at a lower support axis on the support offset downward from the upper support axis and a rear end pivoted at a lower base axis on the base offset downward from the upper base axis. The cushion is shiftable relative to the base between a rear position and a front position on pivoting of the links about the respective axes. A rigid brace is pivoted on the upper link between the upper axes and on the lower link between the lower axes.
