Abstract
Abstract A metal frame for a foam body seating structure having a base and back and supports which extend upwardly from the base. The metal frame is embedded in the foam body and has load resisting bars therein which extend between the base and the back of the seating structure and which also extend between the arms and the base of the seating structure. The load resisting bars have web portions which provide effective load resistance, and wires are provided which interconnect the load bars and form an outline of the desired shape of the foam body.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
In a seat structure which includes an integral foam body having a base and upright arm and back supports which extend upwardly from said base, a frame embedded in said body comprising a first load bar disposed within said base and extending upwardly into said back support to a posiTion near the upper end thereof, said load bar extending front to rear in said base from a position adjacent the front edge of the base, said load bar having at least one perpendicularly extending flange portion extending substantially the full length thereof to resist seating loads acting conjunctively on said back support and said base and disposed in a first upright plane, a second load bar disposed within said base and having end sections which project upwardly into said arm supports, said second load bar being secured to said first load bar and having at least one perpendicularly extending flange portion extending substantially the full length thereof to resist seating loads acting conjunctively on said arm supports and said base and disposed in a second upright plane which is substantially perpendicular to said first upright plane.
Claim 2
Dependent Claim
186 words
In a seat structure which includes an integral foam body having a base and upright arm and back supports which extend upwardly from said base, a frame embedded in said body comprising a first load bar disposed within said base and extending upwardly into said back support to a posiTion near the upper end thereof, said load bar extending front to rear in said base from a position adjacent the front edge of the base, said load bar having at least one perpendicularly extending flange portion extending substantially the full length thereof to resist seating loads acting conjunctively on said back support and said base and disposed in a first upright plane, a second load bar disposed within said base and having end sections which project upwardly into said arm supports, said second load bar being secured to said first load bar and having at least one perpendicularly extending flange portion extending substantially the full length thereof to resist seating loads acting conjunctively on said arm supports and said base and disposed in a second upright plane which is substantially perpendicular to said first upright plane.
Claim 3
Dependent Claim
38 words
The embedded frame that is defined in claim 1 further including a plurality of wires structurally interconnecting said load bars so as to transmit load forces therebetween, said wires being arranged in contoured conformity with said foam body.
Claim 4
Dependent Claim
35 words
The frame according to claim 2 further including another load bar like said first load bar arranged in a substantially parallel spaced relation with said first load bar and secured to said second load bar.
