Abstract
Abstract A seat construction comprising a frame including a base and a back. Each of the base and back have a frame with spaced siderails and a spring assembly mounted on the frame. Each spring assembly comprises a plurality of longitudinally extending wires, a plurality of transversely spaced wires having intermediate portions extending between the spaced wires and free ends extending beyond the longitudinally extending wires at an acute angle to the intermediate portion. Each spring assembly further comprises a longitudinal wire along each side edge connecting the free ends of said transversely spaced wires. Each spring assembly is resiliently supported on its respective frame.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
91 words
In a seat construction, a spring assembly comprising a pair of longitudinally extending wires, a plurality of transversely extending spaced spring wires, portions of said transversely extending spaced spring wires being wound around said longitudinally extending wires to define an intermediate portion extending between the spaced longitudinally extending wires and connected thereto and free ends extending beyond the longitudinally extending wires at an acute angle to the intermediate portion, an additional longitudinally extending wire connecting the free ends of said transversely extending Spring wires along each said first-mentioned longitudinally extending wire.
Claim 2
Dependent Claim
91 words
