Abstract: A padded headrest for the seat back of a motor vehicle includes a stirrup-shaped mounting body pivotally mounted on a horizontal support through vertical supports which are longitudinally adjustably connected to the mounting body and which are fastened in corresponding receiving parts at the seat back. The assembly consists of a device for securing the headrest body in each adjusted inclined position at the horizontal support and is characterized in that the stirrup-shaped mounting body of the headrest body is longitudinally movably guided in at least one helically arranged peripheral recess of a horizontal support having an at least semicircular cross-sectional profile and being attached to vertical supports in a manner preventing the horizontal support from pivoting.
