ABSTRACT:
In the case of a head restraint (1) for a vehicle seat, with a support (5), at least two rockers (15, 25) which are arranged movably on the support (5) and are pivotable about horizontal spindles (7, 17), an impact element (13) which is coupled to the rockers (15, 25) and, with the rockers (15, 25) and the support (5), forms at least one four-bar linkage (31), and a spring (21) as an energy accumulator which drives the four-bar linkage (31) in the event of a crash, so that the impact element (13) extends forward out of a starting position into a crash position, at least one leg (25) of the spring (21) forms one of the rockers.
