<p>The tub is suspended in a frame by one or more tension springs whose ends are curved into open fixing hooks or loops. The tub (3) incorporates suspension lugs (8, 12) each provided with holes (7, 11). When the tub (3) is installed in the frame (2), these lugs fulfil two functions: one is to hold the suspension springs (4, 5) in the mounting position, and the other is to suspend the tub (3), with freedom to oscillate, from the ends of these springs (4, 5) curved into open fixing hooks or loops. <IMAGE></p> |
