Abstract: The protective layer exhibits an oblong web (1), which is to be laid on the surface of the seat, and is made of a thin and flexible film, for example tissue paper. The web (1) is shrunk in its longitudinal direction into a package and provided with a wrapper (3) that can be torn open. The wrapper consists of a separately produced tape (3), which envelops the shrunk web (1) at right angles to the longitudinal direction. For use, the wrapper is torn open at the tab members (A, B) and the web (1) expands, whereby an edge (1b) changes automatically into a position projecting from a seat region (1a).

Abstract: For producing a protective layer made of a sheet, a device exhibits an oblong guide element (1) with an upper edge (2), by way of which a sheet (7) can be folded in its longitudinal direction. Clamping elements (15, 16), designed as sliders, are arranged on the side of the guide element (1); and the sheet (7), folded in its longitudinal direction, can be grasped on both sides of the guide element (1) with said clamping elements. To form folds in the sheet (7), the clamping elements (15, 16) can be slid in the longitudinal direction of the guide element (1).
