Abstract
Abstract The present invention relates to a spring assembly for the seat portions or areas of upholstered furniture. The spring assembly provides a frame and a series of different spring types supported in a generally parallel arrangement within the frame. The spring assembly inlcudes a plurality of upper spaced, elongate sinuous springs extending between and above a pair of opposing front and back members. Located in the central region of the assembly is a rectangular quad coil spring mounted on two upper and lower wire stringers. The spring assembly is provided with a pair of Z-shaped sinuous springs, one located on each lateral side of the quad coil. The Z-shaped springs are mounted on lower elongate sinuous springs extending between the front and back members. The upper portions of the Z-shaped sinuous springs and the upper elongated sinuous springs are secured to the upper and lower stringers for stability and to prevent lateral movement of same. The Z-shaped springs provide for local support independent of the central quad coil. The spring assembly provides a differential response across the top surface thereof in response to a user sitting thereon. When several such assemblies are mounted adjacent one another, the resulting system provides for relative independent spring support between adjacent users.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
189 words
A spring assembly for the seat portion of upholstered furniture, said assembly having at least one spring sub-assembly comprising: (a) a frame having a front and back rails, and (b) side rails; and a series of interconnected springs substantially independently supported within said frame, said series of interconnected springs comprising at least three different types of springs including a plurality of upper elongated sinuous wire springs arranged generally parallel to one another and transversely bridging in a uniform manner the front and back rails, quad-shaped spring means located centrally within said spring assembly, and Z-shaped spring means located centrally between said front and back rails on each side of said quad-shaped spring means between said quad-shaped spring means and said side rails, each of said spring type being capable of exerting a different level of firmness and each being sequentially engaged in order of increasing firmness in response to the application of a person's weight and to provide local support for a user sitting on said spring assembly between said Z-shaped spring means while substantially isolating said user from users sitting in any adjacent sub-assemblies comprising said spring assembly.
Claim 2
Dependent Claim
189 words
A spring assembly for the seat portion of upholstered furniture, said assembly having at least one spring sub-assembly comprising: (a) a frame having a front and back rails, and (b) side rails; and a series of interconnected springs substantially independently supported within said frame, said series of interconnected springs comprising at least three different types of springs including a plurality of upper elongated sinuous wire springs arranged generally parallel to one another and transversely bridging in a uniform manner the front and back rails, quad-shaped spring means located centrally within said spring assembly, and Z-shaped spring means located centrally between said front and back rails on each side of said quad-shaped spring means between said quad-shaped spring means and said side rails, each of said spring type being capable of exerting a different level of firmness and each being sequentially engaged in order of increasing firmness in response to the application of a person's weight and to provide local support for a user sitting on said spring assembly between said Z-shaped spring means while substantially isolating said user from users sitting in any adjacent sub-assemblies comprising said spring assembly.
Claim 3
Dependent Claim
27 words
A spring assembly according to claim 1 comprising at least two identical spring sub-assemblies positioned adjacent each other so as to have one side rail in common.
Claim 4
Dependent Claim
221 words
A spring assembly for the seat portion of upholstered furniture, said assembly having at least one spring sub-assembly comprising: (a) a generally rectangular frame including a back rail, two side rails and a front rail; (b) a plurality of first, upper elongated sinuous wire springs arranged generally parallel to one another and transversely bridging in a uniform manner the back rail and the front rail at a height above the height of the rails so as to provide a spring effect when a downward pressure is applied thereto; (c) quad-shaped spring means located centrally within the spring assembly and providing general support in the central area of the spring assembly; (d) Z-shaped spring means located centrally between said back and front rails on each side of said quad-shaped spring means between said quad-shaped spring means and said side rails for providing local support in said spring sub-assembly between said quad-shaped spring means and each side rail; (e) means for supporting said Z-shaped spring means within the spring sub-assembly; and (f) upper stabilizing means interconnecting each of said plurality of first, upper elongated sinuous wire springs with one another and with said quad-shaped and said Z-shaped spring means, and lower stabilizing means supporting said quad-shaped spring means and interconnecting said quad-shaped spring means with said means for supporting said Z-shaped spring means.
Claim 5
Dependent Claim
221 words
A spring assembly for the seat portion of upholstered furniture, said assembly having at least one spring sub-assembly comprising: (a) a generally rectangular frame including a back rail, two side rails and a front rail; (b) a plurality of first, upper elongated sinuous wire springs arranged generally parallel to one another and transversely bridging in a uniform manner the back rail and the front rail at a height above the height of the rails so as to provide a spring effect when a downward pressure is applied thereto; (c) quad-shaped spring means located centrally within the spring assembly and providing general support in the central area of the spring assembly; (d) Z-shaped spring means located centrally between said back and front rails on each side of said quad-shaped spring means between said quad-shaped spring means and said side rails for providing local support in said spring sub-assembly between said quad-shaped spring means and each side rail; (e) means for supporting said Z-shaped spring means within the spring sub-assembly; and (f) upper stabilizing means interconnecting each of said plurality of first, upper elongated sinuous wire springs with one another and with said quad-shaped and said Z-shaped spring means, and lower stabilizing means supporting said quad-shaped spring means and interconnecting said quad-shaped spring means with said means for supporting said Z-shaped spring means.
Claim 6
Dependent Claim
144 words
The spring assembly of claim 3 wherein said Z-shaped spring means comprises two Z-shaped sinuous springs and said means for supporting said Z-shaped sinuous spring comprises second, lower elongated sinuous springs extending from the back rail to the front rail at a height below the height of said plurality of first, upper elongated sinuous springs, and wherein said quad-shaped spring means includes a base and said lower stabilizing means comprises stringer members extending from the base of said quad-shaped spring to said second, lower elongated sinuous springs, said upper stabilizing means comprising stringer members interconnecting said plurality of first, upper elongated sinuous springs with said quad-shaped spring and said Z-shaped sinuous springs, said stringer members being attached to said quad-shaped spring and to said Z-shaped sinuous springs and to said first upper and said second lower elongated sinuous springs by means of crimped sleeves.
Claim 7
Dependent Claim
