The Vflexible .metallic bandll 2l=yields and the shroud support'. I A yields "bellying-outso as to vpermit theA sides to iiex outwardly and twist, as shownlin Figurezf This: outward movement" of the margins of th'ecushion,..inladdition to increasing the softfeeling.y of the: cushion, prolon'gs' the life ofl ther strands,i,bo.th thefwarp andllthewe'ftwires -in the screen, in that the outward movement prevents This cushionmember is.

iiexing of the wire over a short distance. This arrangement permits the use of the screen wire in a large cushion or seat that may be comparatively deep, in that the downward movement of the outer cushion member I is limited by the more rigid inner cushioning member 20 which functions as an inner spring.

In the modification disclosed in Figures 4 and 5, the outer cushion member I0, the flexible band I2 and the shroud support I4 may be identical to the preferred embodiment shown in Figures 1, 2 and 3. Instead of an inner cushioning member, as shown in the preferred embodiment, a comparatively stiff horizontally disposed screen member 30 provided with downwardly projecting peripheral flanges 32 is secured at thecorners to the exible band I2, the margin of the outer cushion member I0 and the shroud support III by a plurality of rivets 34. By attaching the horizontal screen member 30 by the four corners, leaving the sides free to move, the center of the screen is permitted to yield sufficiently to give the eiect of a cushion. The margins of the outer cushion member I0, the flexible band l2 and the shroud support I4 may move outwardly in a manner substantially identical to that described in connection with the preferred embodiment. The lower margin of the shroud support I4 is riveted to a rather rigid supporting band 36 by a plurality of rivets 38. This coniines and rigidly holds the shroud support, permitting the upper margin of the shroud support to flex outwardly with the margin of the outer cover I0.

For some purposes suitable high carbon steel wire or other spring wire may be used in connection with the shroud support without any other spring or cushion, in which event the entire weight is absorbed by the outer spring member I0. In the event the inner spring is eliminated, which it may be for many purposes, the outer member I D is then made from stiffer spring wire, so as to offer sufcient resiliency to properly absorb the weight of the occupant. The shroud support I4 permits the margins of the main cushion member I0 to flex outwardly, thereby producing a softer cushion and prolonging the life of the spring Wires.

Although the preferred embodiment of the device has been described, it will'beV understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
