These braces extend forwardly and downwardlyl and are secured to the end f memberslz of'the front border frame by. means of clips 33.v The end members I2 are bowed outwardly to suitably shape the cushion to. the particular installation and spring units 34 of the type described are connected at their outer ends to the end frame members by the clips 35 and at their inner endsto'adjacent-bends of the spring units by clips 36.

Helical tie members 37 connect adjacent loops ofthe spring members while helical '

coils

38 and 38 vare provided to connect certain of the loops of the end spring elements tothe end frame Y, members.

'The'upholstery supporting mat I6 is reinforced Ifby;,parallel strands of resilient wire 48. The

mat rests llpn the bowed spring elements. The Y bowed spring elements, that is, disregarding the rearwardly turned arms thereof, are of the type illustrated in 'the Clark Patent No. 2,314,923 is- ','s'ued March "30,'` 1943.

They might be described as being of the; zig-Zag type and arranged in connectedpairs." It "will beunderstood that otherV `formsY or shapesjof Vthe zig-zag type'of springs than thoser illustrated might be used. Withftheupholstery 'supporting springs thus v mounted andfsupported, when they are subjected to compressivestresses their. lower ends swing rearwardly and downwardly as is indicated by j'dotted lines' in Fig. y1. relation of the `lower end of the'cushion to the seat cushion is' maintainedunder varying load conditions.

3. A back cushion comprising a rear frame including a cross bar of sheet metal disposed in vertically spacedV relation tothe lower end of the cushion and havinga downwardly bent flange adjacent its upper edge providing a downwardly facing channel extending longitudinally of the cross bar, a row of springs mounted at the upper end of the rear frame to project forwardly therefrom, connected top and bottom front frame members, the top memberbeing supported by said coiled springs, and ra plurality of vertically disposed forwardly bowed spring units having integral springable vrearwardly and upwardly projecting supporting arms at their lower ends, the upper ends of the arms having laterally turned ends extending longitudinally of the cross bar in thev downwardly facing'channel thereof, upper ends of the spring units being secured to the top member of the front frame, the lower ends of said spring units being secured to the bottom front frame member. I

4. A spring cushion. assembly including a seat cushion and a back cushion associated therewith, with the lower end ofthe back cushion overhanging the rear vend of the seat cushion and closely adjacent thereto, the back cushion comprising a rear frame, top and bottom front frame memposed loops therein of substantial length extending transversely of the length of the unit and having reaches between the loops disposed lengthwise of the unit in side by side relation and a helical tie member threaded upon said reaches, said units having rearwardly and upwardly projecting supporting arms at their lower ends mounted at their upper ends on the rear frame, the lower ends of said spring units being secured to the bottom front frame member, and upholstery arranged over and supported by said spring units whereby simultaneous compressive stresses on the seat and back cushions act to maintain the lower end of the back cushion in adjacent relation to the compressed seat cushion.

5. A back cushion comprising a rear frame, top and bottom front frame members, the top member being spring supported, and a plurality of vertically disposed forwardly bowed spring units each comprising strands of spring wire having longitudinally spaced oppositely disposed loops therein of substantial length extending transversely of the length of the unit and having reaches between the loops disposed lengthwise of the unit in side by side relation and a helical tie member threaded upon said reaches, said units having rearwardly and upwardly projecting supporting arms at their lower ends mounted at their upper ends on the rear frame, the lower ends of said spring units being secured to the bottom front frame member.

6.
