<p>The seat consists essentially of a seat frame and a back rest frame, which are screwed to each other by way of plates which are welded thereto. The seat frame and back rest frame each consist of a curved sectional member, whereof the ends are constructed as skid-type feet. The seat frame and back rest frame are each strengthened by a transverse reinforcement and, when the surface of the seat or back rest includes a lattice, is welded to the frame, when the surface of the seat or back rest includes a plastic shell, it is attached to the frame by clamping.</p> |
