Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a seat back support structure and a seat. Background Art

[0002] Existing office chairs consist of a footrest, a seat, and a backrest. The footrest is typically a single-column, five-prong, center-supported type. The upper end of the footrest column is equipped with a lift adjustment mechanism, which is connected to the center of the seat bottom. This allows the seat to flexibly rotate relative to the footrest and adjust its height to suit work needs. Typical office chairs also feature a backrest. The bottom of the seat is provided with a backrest connection, which is connected to the seat via an L-shaped backbar (metal backbar). The lower end of the L-shaped backbar is inserted into a mounting slot in the backrest connection base, while the upper end of the L-shaped backbar is fixedly or movably mounted to the backrest board.

[0003] However, the L-shaped back bar in the prior art is usually exposed, which not only affects the aesthetics of the back of the chair, but also makes it easy for people to accidentally bump into the L-shaped back bar, causing the anti-rust paint on the surface of the L-shaped back bar to fall off, thereby causing the L-shaped back bar to rust and be damaged. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a seat back support structure and a seat.

[0007] As a further improvement of the present invention, a plurality of connecting rods are provided on the inner side of the protective cover, and a mounting groove is provided at one end of the connecting rod close to the back rod. A magnetic part is provided in the mounting groove for adsorbing the protective cover on the back rod.

[0008] As a further improvement of the present invention, at least one positioning rod is provided on the inner side of the protective cover, and at least one positioning groove is provided on the connecting member, and the positioning groove is used for the positioning rod to penetrate for installation and positioning.

[0009] As a further improvement of the present invention, the back rod includes a vertical connecting portion vertically arranged for connecting the upper end to the connecting piece, and a horizontal connecting portion arranged at the lower end of the vertical connecting portion and bent to one side for connecting to the bottom of the seat.

[0010] As a further improvement of the present invention, the protective cover is provided with an accommodating cavity for accommodating the vertical connecting portion, and the horizontal connecting portion passes through the accommodating cavity.

[0011] As a further improvement of the present invention, the protective cover is provided with a group of limiting plates in the accommodating cavity, and a preset spacing matching the width of the back rod is provided between the limiting plates.

[0012] As a further improvement of the present invention, the protective cover is provided with a plurality of reinforcing ribs in the accommodating cavity.

[0013] As a further improvement of the present invention, the back rod is connected to the connecting member and the seat seat by bolts.

[0014] Based on the same concept, the utility model patent also discloses a seat, including a seat seat, a seat back arranged on the seat seat, and also includes the seat back support structure as described above.

[0015] The beneficial effects of the present invention are as follows: a protective cover is provided on the outside of the back rod, which prevents people from directly touching the back rod, thereby avoiding damage to the back rod; at the same time, the protective cover can be made into various shapes, which not only prevents the back rod from being exposed to the outside, but also improves the aesthetics of the back of the chair.

[0016] A further effect is that the back rod in the utility model is an alloy steel frame (such as stainless steel), the magnetic part can be adsorbed on the back rod, and the protective cover is connected and installed by magnetic attraction, which has a simple structure and is easy to disassemble and assemble.
