Abstract
Abstract This device relates to a headrest for a motor vehicle seat, which consists of a head-piece and a holder. The headpiece comprises the supporting frame assuming a stress-bearing function and an upholstery body providing a padding effect. The holder is single-strutted, can be inserted into the back-rest of a motor vehicle seat, and is preferably height-adjustable. With respect to the latter, it is hinged to the head-piece, so that this can be adjusted in frictional engagement to different angular positions with respect to the holder.
