Seat frames having appearance of one-piece construction and seat frames having a back support design derived from the frame

A method for forming a seat frame, the method consisting of:

• forming at least one of a single continuous elongated member and a plurality of elongated members into a plurality of legs, a backrest, and a support for a seat, and wherein the plurality of legs, the backrest, and the support for the seat form the seat frame having an appearance of being integrally formed from a single continuous elongated piece of material having a longitudinal axis along an entire length of the single continuous elongated piece of material and defining a single beginning first end disposed across the longitudinal axis, a single terminating second end disposed across the longitudinal axis, and a single continuous elongated middle portion defining a single continuous uninterrupted course along the entire length of the longitudinal axis between the single beginning first end and the single terminating second end, and the single continuous elongated piece of material comprise a generally constant cross-sectional shape taken about the longitudinal axis and along the entire length of the single continuous elongated piece of material, the backrest formed from a portion of the single continuous elongated middle portion, the single beginning first end disposed across the longitudinal axis and the single terminating second end disposed across the longitudinal axis defining ends of first and second legs of the plurality of legs for supporting the seat frame on a surface so that said single beginning first end and said single terminating second end rest on the surface and adjacent terminating end portions extend directly upwardly away from the surface, and portions of the single continuous elongated middle portion defining ends of third and fourth legs of said plurality of legs for supporting the seat frame on the surface.

A seat frame consisting of:

• a plurality of legs;
• a backrest;
• a support for a seat;
• wherein said plurality of legs, said backrest, and said support for the seat form said seat frame having an appearance of being integrally formed from a single continuous elongated piece of material having a longitudinal axis along an entire length of the single continuous elongated piece of material and defining a single beginning first end disposed across said longitudinal axis, a single terminating second end disposed across said longitudinal axis, and a single continuous elongated middle portion defining a single continuous uninterrupted course along said entire length of said longitudinal axis between said single beginning first end and said single terminating second end, and
• wherein said single continuous elongated piece of material comprises a generally constant cross-sectional shape taken about said longitudinal axis and along said entire length of said elongated piece of material, said single beginning first end spaced-apart from said single terminating second end, said backrest formed from a portion of said single continuous elongated middle portion, and said single beginning first end disposed across said longitudinal axis and said single terminating second end disposed across said longitudinal axis defining two ends of first and second legs of said plurality of legs for supporting said seat frame on a surface so that said single beginning first end and said single terminating second end rest on the surface and adjacent terminating end portions extend directly upwardly away from the surface, and portions of said single continuous elongated middle portion defining ends of third and fourth legs of said plurality of leas for supporting said seat frame on the surface.
