The backrest cover(1) on both sides(4,5) of the seat has slotted opening(8,9) covered by an overlap(6,7) or cover. Both openings are positioned by the same distance from, and symmetrically to, an imaginary centre line and have two approximately parallel edges(10,11) of which one is bordered by an elastic band(12) and the other by a hemmed edge(13). In the fitted state of the backrest cover the hemmed edges are covered by the elastic bands or opening edges(10). |
