The rectangular seat frame is formed of rectangular tubes on edge and accommodates cushions and hinged backrest frames with cushions, also a support underframe. The rectangular seat frame (1) tubes form a rectangle (3) while hinge brackets (5) extend upwards at roughly 45 deg. from the rear tube to accommodate the backrest (2). The latter are joined together by a stiffening bar (6). Each backrest frame (2) has a stiffenging tube (10) near the hinge. |
