An article of furniture may include a component such as a frame, leg, or support. The component may be constructed from a strip of material and the strip of material may include a strip length, a strip width, and a strip thickness. The component may include a longitudinal welding joint that may be disposed between a first strip end or a first strip side and a second strip end or second strip side. A profile may be embossed into a surface of the strip of material and the component may be manufactured in a continuous inline roll forming process.

The invention relates to a frame furniture comprising a furniture element (14) being plate-shaped at least in some areas and having an at least partially nearly horizontal extension and being arranged on a carrier frame (18) which has a leg element (20A, 20B) on both sides, respectively, regarding a vertical furniture median plane, the leg element (20A, 20B) consisting of a tubular element bent in such a way that the tubular element forms a front and rear furniture leg (22A, 22B, 24A, 24B). The tubular elements each have an elliptical or oval cross section having a long major axis and a short minor axis, wherein the major axis and the minor axis intersect with the vertical furniture median plane over the length of the particular tubular element at an angle less than 90.

A vehicle seat includes a seat frame. The seat frame has a hollow deformable portion that is bent, and linear recessed portions formed by partially recessing an inner side of the deformable portion. The deformable portion has a linear separation portion formed in a projecting manner relative to the recessed portions and extending on the inner side of the deformable portion. A plurality of recessed portions is formed on each of one side and the other side of the separation portion so as to sandwich the separation portion, and placed independently from each other such that adjacent recessed portions are not connected to each other.

A foldable plastic-steel chair comprises a seat board assembly, a backrest, and a metal supporting frame. The seat board assembly and the backrest are connected to the metal supporting frame, and the seat board assembly comprises a seat board. The seat board comprises a surface plate and a surrounding edge connected to a periphery of the surface plate and extending downward, and the seat board is a vacuum-formed plastic board. The seat board assembly further comprises a metal frame abutting a periphery of seat board, and a bottom end of the metal frame is bent outward to form a hook. A lower end portion of the surrounding edge of the seat board is disposed in the hook, and a portion of the metal frame abuts an inner side of the surrounding edge. The hook is fixedly clamped to a lower edge of the surrounding edge.

A chair comprises: two side frames, each of the two side frames comprising a front supporting leg and a rear supporting leg; a seat portion fixed between the two side frames; and a backrest portion connected to the rear supporting legs of the two side frames via a plug structure.

The invention relates to a frame furniture comprising a furniture element (14) being plate-shaped at least in some areas and having an at least partially nearly horizontal extension and being arranged on a carrier frame (18) which has a leg element (20A, 20B) on both sides, respectively, regarding a vertical furniture median plane, the leg element (20A, 20B) consisting of a tubular element bent in such a way that the tubular element forms a front and rear furniture leg (22A, 22B, 24A, 24B). The tubular elements each have an elliptical or oval cross section having a long major axis and a short minor axis, wherein the major axis and the minor axis intersect with the vertical furniture median plane over the length of the particular tubular element at an angle less than 90 .

The present disclosure relates to a deformation-resistant load-bearing rod for a seat, aiming to solve the problems of plastic deformation and structural failure after long-term use in existing technologies. The load-bearing rod for a seat comprises a rod and a load-bearing part. The rod adopts a hollow cylindrical structure to optimize the moment of inertia of the cross-section, and both ends are connected to the seat through mounting holes in a three-point fastening manner. The inner wall has anti-slip threads to ensure stability under dynamic loads. The load-bearing part is designed as a racetrack-shaped curved column, with its radially extending load-bearing wall forming a sleeve structure with the rod. The load-bearing part can rotate axially around the rod to dynamically adjust the stress angle, thereby extending the fatigue life of the material.
