Abstract

A vehicle seat has a backrest and a back massage device provided at the backrest. The massage device exhibits electrically and/or mechanically operated pressure elements for exerting pressure onto the back of an occupant. The pressure elements are arranged along the longitudinal direction of the backrest between the seat area and the head area at different heights with pressure elements located nearer the seat (lower pressure elements) provided essentially in the area of the lumbar vertebrae of the backrest and pressure elements located above them (upper pressure elements). In the area of at least one of the upper pressure elements, the backrest is designed such that when at least operating the at least one upper pressure element, a force is exerted onto an occupant perpendicular to the surface of the back rest, said force being increased in this area compared to the area of the lower pressure element.
