Seat construction

Claim 2

A seat of modular construction comprising a skeletal frame having interconnected seating and back rest frame components, separately formed side arms of reinforced rigid foam connected to opposite sides of said skeletal frame and having upwardly extending rear portions engaging upper side portions of said skeletal frame, at least one modular cushioned seat and one modular cushioned back rest carried by said skeletal frame, each modular cushioned seat and modular cushioned back rest comprising a supporting sub-assembly and resilient foam overlying and connected to said supporting sub-assembly, and side arm cushions comprising resilient foam secured to a reinforcing substrate, said side arm cushions overLying and carried by said side arms and extending downwardly a predetermined extent along opposite sides thereof.

Claim 3

A seat according to claim 1, wherein said skeletal frame is of a length suitable for a sofa, and a plurality of modular cushioned seats and modular cushioned back rests are carried by said skeletal frame.

Claim 4

A seat according to claim 1, wherein said supporting sub-assembly for each modular cushioned seat and modular cushioned back rest comprises an elongate frame unit and a series of spaced apart elongate pliable members secured to said frame unit and extending lengthwise thereof.

Claim 5

A seat according to claim 1, wherein said side arms have tapered upper portions of a smaller width dimension than lower portions thereof and wherein said side arm cushions are matingly and straddlingly positioned on said tapered portion of said side arms.

Claim 6

A seat according to claim 1, wherein fastening means are provided for interconnecting said side arm cushions to said side arms, said fastening means extending through outer portions of said side arm cushions and into upper portions of said side arms.

Claim 7

A seat according to claim 1, wherein said side arm cushions comprise molded resilient foam of substantially inverted U-shape in cross-section and wherein said reinforcing substrate is secured to said foam and extends along the inner surface of the foam between the legs thereof defined by the substantially U-shape configuration.

Claim 8

A seat according to claim 1, wherein said side arm cushions each comprise an elongate series of resilient foam pads positioned in side by side relation and each being substantially inverted U-shape in cross-section, and an elongate covering overlying each series of foam pads, said covering including transversely arranged drawstrings carried thereby for pleatingly positioning and maintaining portions of the covering between adjacent foam pads of the series.

Claim 9

A seat according to claim 7, wherein fibrous padding is positioned between each series of foam pads and said overlying covering.

Claim 10

A seat of modular construction comprising a skeletal frame having interconnected seating and back rest frame components, separately formed side arms formed of reinforced rigid foam connected to opposite sides of said skeletal frame and having upwardly extending rear portions engaging upper side portions of said skeletal frame, at least one modular cushioned seat and one modular cushioned back rest carried by said skeletal frame, said modular cushioned seat comprising resilient foam having integrally formed therewith a downwardly depending frontal lip portion overlying frontal portions of the skeletal frame, said modular cushioned back rest comprising resilient foam having integrally formed therewith a downwardly depending rear lip portion overlying upper rear portions of the skeletal frame, and side arm cushions comprising resilient foam secured to a reinforcing substrate, said side arm cushions overlying and carried by said side arms and extending downwardly a predetermined extent along opposite sides thereof.

Claim 11

A seat of modular construction comprising a skeletal frame having interconnected seating and back rest frame components, separately formed side arms formed of reinforced rigid foam connected to opposite sides of said skeletal frame and having upwardly extending rear portions engaging upper side portions of said skeletal frame, at least one modular cushioned seat and one modular cushioned back rest carried by said skeletal frame, said modular cushioned seat comprising resilient foam having integrally formed therewith a downwardly depending frontal lip portion overlying frontal portions of the skeletal frame, said modular cushioned back rest comprising resilient foam having integrally formed therewith a downwardly depending rear lip portion overlying upper rear portions of the skeletal frame, and side arm cushions comprising resilient foam secured to a reinforcing substrate, said side arm cushions overlying and carried by said side arms and extending downwardly a predetermined extent along opposite sides thereof.

Claim 12

A seat according to claim 9, wherein a reinforcing substrate is secured to the upper rear portion of said skeletal frame underlying said resilient foam rear lip portion for reinforcing the same.

Claim 13

A seat of modular construction comprising a skeletal frame having interconnected seating and back rest frame components, side arms formed of reinforced rigid foam and having tapered upper portions of a smaller width dimension than lower portions thereof, said side arms being connected to opposite sides of said skeletal frame and having upwardly extending rear portions engaging upper side portions of said skeletal frame, at least one modular cushioned seat and one modular cushioned back rest carried by said skeletal frame, each modular cushioned seat and modular cushioned back rest comprising a supporting sub-assembly and resilient foam overlying and connected to said supporting sub-assembly, and side arm cushionS matingly and straddlingly positioned on said tapered portion of said side arms and extending downwardly a predetermined extent along opposite sides thereof.

Claim 14

A seat of modular construction comprising a skeletal frame having interconnected seating and back rest frame components, side arms formed of reinforced rigid foam and having tapered upper portions of a smaller width dimension than lower portions thereof, said side arms being connected to opposite sides of said skeletal frame and having upwardly extending rear portions engaging upper side portions of said skeletal frame, at least one modular cushioned seat and one modular cushioned back rest carried by said skeletal frame, each modular cushioned seat and modular cushioned back rest comprising a supporting sub-assembly and resilient foam overlying and connected to said supporting sub-assembly, and side arm cushionS matingly and straddlingly positioned on said tapered portion of said side arms and extending downwardly a predetermined extent along opposite sides thereof.
