Abstract: A backrest for a vehicle seat includes a backrest frame, which is surrounded by a cover and has an upper backrest with an adjustable inclination. An additional frame is hinged so as to be pivotable about a pivot axis to a side plate, the cover, or the backrest frame. The pivot axis is arranged in an upper region of the backrest, and the additional frame extends upwards from the pivot axis in the installed position of the backrest. The additional frame can be secured in different angular positions in relation to the backrest frame, and, thus, a variable gap forms between the additional cover of the additional frame and the cover of the backrest frame.

Abstract: An at least partially moveable motor-vehicle outer skin is already known per se. An actuator formed of a polymer and/or ion-exchanging and/or other material exhibiting various conformations is provided so that the outer skin can be moved. This material is moveable as a result of physical or chemical effects. The novel outer skin of a motor vehicle requires no expensive tools for the production thereof. The flat section of the outer skin of the bodywork of a motor vehicle is made of a flexible material. A flexible material such as material for convertible top covers is easily moveable yet the surface thereof cannot be increased. This material is tensed at least over one part of the rib of the motor vehicle, e.g. over a space frame. At least one mechanically moveable adjusting element is provided beneath or on top of the edge of the section enabling the outer skin to be deformed. The adjusting element is normally connected to the rib of the motor vehicle.
