Abstract: A seat frame assembly for a motor vehicle comprises a seat frame and a seat back frame. The seat frame is constructed and arranged to have a seat cushion mounted thereon in overlying relation. The seat back frame is connected with the seat frame and has a pair of spaced metallic vertical support portions at opposite sides thereof, the seat back frame constructed and arranged to have a seat back cushion mounted thereon. At least one of the vertical support portions are formed from a pair of telescoping tubular blanks including an elongated inner metal blank formed into an integrally formed vertical member of the at least one vertical portion extending from a lower portion of the seat back frame connected with the seat frame to an upper end of the seat back frame and a relatively shorter outer metal blank formed into a sleeve rigidly secured in surrounding relation to the lower portion of the vertical support member.

Abstract: A furniture frame construction of the disclosure includes a framework of steel frame members that support a spring assembly for a seat cushion. Front and rear frame members of the framework are fabricated from relatively thin steel stock and have closed cross-sections with projecting flanges secured to each other. End frame members of the framework are also fabricated from relatively thin steel stock with channel cross-sections and interconnect the front and rear frame members with each other. The spring assembly includes a primary spring of the formed wire type extending between the front and rear frame members. The front end of the primary spring includes a fishmouth section that spaces a support section of this spring above the front frame member. The rear end of the primary spring includes a helical coil with a tail that supports the rear end of the support section on the rear frame member. An auxiliary spring of the spring assembly is secured to the lower side of the primary spring support section.
