Abstract
811,094. Spring upholstery. GREAVES & THOMAS Ltd., and COBB, W. R. Sept. 9, 1957, No. 28377/57. Class 52(4) A resilient supporting surface comprises four or more tension springs 1 anchored at their outer ends to a rectangular framework (not shown) at or near the corners and indirectly connected at their inner ends through flexible, non-extensible members 2 to a non-extensible centre member 3. The angle and effective rate of the springs may be changed by altering the length of non-extensible members 2a, 2b. Marginal springs 5 may be provided.
