Abstract

A deflection limitation system for upholstered furniture seat members includes a rectangular-shaped support frame having opposed front and rear members and opposed sides. Sinuous-shaped springs are connected to both the front and rear members. Each spring is deflectable over a limited range defined between a non-deflected position and a maximum deflected position. A wire element crossing below the spring elements has ends each connected to different frame sides. A central portion of the wire element is downwardly curved. A predefined spacing separates the wire element central portion from each of the spring elements in the non-deflected position. The maximum deflected position of the spring elements wherein the spring elements contact the central portion of the wire element is reached when a predefined load is distributed to the spring elements. The spring elements are thereafter restrained from further deflection by the wire element.
