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

Crash-active head restraint

In a headrest () for a vehicle seat, having a support (), at least one upper and lower linkage () hinged to the support (), which are pivotable around horizontal axles (), an impact element () hinged to the linkages (), which forms at least one four-bar linkage () with the linkages () and the support (), and an energy storage, the energy storage driving the four-bar linkage () in the event of a crash, so that the impact element () is driven out forwardly from an initial position into a crash position that is locked rearward by a crash lock, a drive () is provided by way of which, in normal use, the headrest () can be brought from its initial position to at least one other comfort position.

Crash-active headrest

In a headrest () for a vehicle seat, having a carrier (), at least one upper and lower linkage () linked to the carrier (), which can be pivoted around horizontal axles (), a impact element () linked to the linkages () which forms at least one four-bar linkage () with the linkages () and the carrier (), and an energy storage device (), the energy storage device () driving the four-bar linkage () in the event of a crash, so that the impact element () comes out forward from an original position into a crash position that is locked against a backward movement by a crash lock, the upper linkage () and the lower linkage () are unparallel with respect to one another.
