Abstract

A head rest support mechanism for a vehicle seat, the head rest being fitted with at least one support rod having a plurality of notches and being supported by the seat back and adapted for vertical adjustment with respect thereto, the support mechanism further including a guiding member fixed to the seat back and comprising a bore slidingly and snugly supporting the support rod. There is a latching spring supported by the guiding member and having one end fixed to the guiding member, another end projecting from the guiding member, and an intermediate, looped, notch engaging portion being normally biased to engage a portion of a notch. The support rod comprises a plurality of notches each lying in a plane which is perpendicular to a longitudinal axis of the rod and a normal of the plane is not perpendicular to the longitudinal axis. The arrangement is such that axial displacement of the support rod in an upward direction entails lateral displacement of the notch engaging portion so as to disengage from the notch, and downward displacement of the supporting rod is possible only upon laterally displacing the notch engaging portion by expelling the projecting end of the latching spring.
