Abstract
Herein disclosed is an angular position adjustable headrest which comprises a headrest frame. The headrest frame is arranged to pivot between two extreme positions about the axis of a pivot shaft which extends between two spaced brackets secured to a stay of the headrest. A position locking device is arranged to lock the headrest frame to selected one of angular positions of the headrest frame relative to the brackets. A lock cancelling plate is pivotally disposed about the pivot shaft, which disables the position locking device when the headrest frame is pivoted to one of the two extreme positions.
