Sofa seat frame

Abstract

The invention discloses a sofa seat frame, comprising a frame and several elastic members disposed in the frame. The frame comprises two symmetrically-disposed longitudinal beams and two crossbeams for connecting the two longitudinal beams. The cross section of the longitudinal beams is L-shaped and includes a vertical plate and a horizontal plate. The vertical plate and the horizontal plate forma placement cavity, and both ends of the horizontal plate in the length direction are bent towards the inner side of the placement cavity to form a folded edge. The two crossbeams are symmetrically disposed on folded edges at both ends of the longitudinal beams and located in the placement cavity. The sofa seat frame also comprises at least a supported beam, which is connected with the two crossbeams. In comparison with existing sofa seat frame structures, the invention has the following advantages: under the precondition of guaranteeing support strength of the seat frame, the production efficiency of components is improved, manufacturing materials are reduced, production cost is decreased, and complicated assembly process and required parts are simplified; and automation is easy to realize.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a sofa seat frame. Background technique [0002] The furniture industry has always been a labor-intensive traditional industry. The production process requires a lot of labor and production materials, and the production efficiency is low. For example, in the current sofa seat frame, the frame that constitutes the main load-bearing parts is generally welded by rectangular steel or channel steel. Due to the stress of the frame and the connection problem with other sofa components, the frame cannot meet the requirements of the left and right beams, front and rear beams at the same time. The requirements for mutual replacement and the requirement of less materials for overall manufacturing lead to many types of components, difficult production, and large materials used, which is not conducive to the expanded production of enterprises.
