Abstract

A seat back (35) with a headrest (40) on a vehicle seat (33). To reduce the whiplash effect during a front-end accident to a significant degree, the head rest (40) rests on a headrest support (38) that can be pivoted outward and forward around a horizontal axis (39), with the backward displacement of the support being restricted in terms of movement.
