摘要

The seat headrest (1) has a holder (2) which is secured to the backrest of an automobile passenger seat, a relatively pivoted carrier structure (1b) for the headrest and a pivot drive device for pivotong the headrest about a horizontal axis (1a). The pivot drive device uses a lever drive (3) with a sliding element (3a) displaced relative to the holder, coupled to a pivot lever (3b) which is attached to the carrier structure at its opposite end. The sliding element is acted on by a coupling element (4) associated with a relatively spaced adjustment drive.
