Abstract
Abstract A headrest for back seats in station wagons arranged on a forwardly foldable seat back is arranged on or is integrated with an arm pivotally arranged at the top, rear edge of the back seat, to be swung out of the way from a use position to a stowage position beneath the seat back when the seat back is folded down. The arm can be articulated and be slidably arranged in a sleeve mounted on the rear side of the seat back. When the headrest is in the stowage position, the seat back can be folded forwards and the headrest will be well-protected and out of the way in the cavity under the seat back which would otherwise be unused.
