Description

Technical Field

[0001] The utility model relates to the technical field of chairs, in particular to a detachable backrest seat. Background Art

[0002] There are many types of foldable chairs on the market, but their most common drawbacks include being bulky when folded, heavy, and difficult to carry. Furthermore, while foldable chairs were originally designed for ease of portability and storage, in practice, the complexity of their structure and materials often results in a relatively large folded volume and weight, hindering portability. This is particularly evident when choosing outdoor camping chairs. While foldable chairs offer superior comfort and stability, they lack portability.

[0003] Prior art, such as Chinese Patent Publication No. CN204245643U, provides a detachable chair for easy portability. This chair, with its housing and detachable legs, can be disassembled to form a suitcase, making it convenient to carry while taking up minimal space. However, because both the seat and backrest are rigid, this significantly reduces user comfort and fails to achieve the desired effect of ensuring both comfort and portability. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detachable backrest chair, characterized by comprising: a main frame, a flexible seat cushion, a seat cushion connector, a backrest frame, a flexible back cushion, a backrest connector, and chair legs. The main frame is detachably connected to the backrest frame; the main frame is detachably connected to the chair legs; the flexible seat cushion is provided on the main frame, and the main frame and the flexible seat cushion are connected via the seat cushion connector; the flexible back cushion is provided on the backrest frame, and the backrest frame and the flexible back cushion are connected via the backrest connector.

[0006] Through the above technical solution, the detachable backrest seat involved in the utility model can achieve the technical effect of being easy to carry while ensuring comfort in use.

[0007] In some embodiments, the main bracket includes two side frames, an X-shaped bracket is fixedly arranged between the two side frames, and chair leg sockets are opened under the two side frames. Chair legs are detachably connected to the chair leg sockets, and the side frames and the chair legs are fixed by bolts.

[0008] In some embodiments, an anti-slip rubber pad is provided at one end of the chair leg away from the main support.

[0009] This arrangement can enhance the stability of the backrest seat when in use.

[0010] In some embodiments, the seat cushion connector includes a seat cushion fixing frame, a plurality of seat cushion fixing plates are fixedly connected to the seat cushion fixing frame, and the seat cushion fixing plates are provided with through holes.

[0011] This arrangement can ensure a stable connection between the flexible seat cushion and the main bracket, preventing the flexible seat cushion from falling off when bearing weight.

[0012] In some embodiments, the flexible seat cushion is provided with a plurality of through holes, the main bracket is provided with a plurality of threaded holes, and the seat cushion connector, the flexible seat cushion and the main bracket are connected by bolts.

[0013] In some embodiments, the backrest frame includes a U-shaped frame and a support bar fixedly arranged on the U-shaped frame, a backrest socket is provided on the main bracket, and the U-shaped frame is detachably connected to the backrest socket and fixed by bolts.

[0014] With this arrangement, the user can be supported by the support strip when leaning against the flexible back pad, thereby improving the user's comfort.

[0015] In some embodiments, the backrest connector includes a backrest fixing frame, a plurality of backrest fixing plates are fixedly connected to the backrest fixing frame, and the backrest fixing plates are provided with through holes.

[0016] In some embodiments, the flexible back pad is provided with a plurality of through holes, the back frame is provided with a plurality of threaded holes, and the back connector, the flexible back pad and the back frame are connected by bolts.

[0017] This arrangement can ensure a stable connection between the flexible back cushion and the backrest frame, and prevent the flexible back cushion from falling off when bearing weight.

[0018] In some embodiments, the main support, the backrest frame, the seat cushion connector and the backrest connector all have smooth transitions at their corners.

[0019] Such an arrangement can prevent the backrest seat from causing damage to the user due to collision when in use.

[0020] In some embodiments, the main support, the backrest frame, and the chair legs are all hollow structures.

[0021] Such an arrangement can reduce the overall weight of the backrest seat while ensuring the overall mechanical strength of the backrest seat, making it lighter and easier to carry.

[0022] To sum up, compared with the existing technology, the utility model has the following beneficial effects: the seat has a flexible seat cushion and a flexible back cushion, which can ensure comfort in use, and the backrest and legs of the seat are both detachable structures, which are easy to carry after disassembly. It can achieve the technical effect of being easy to carry while ensuring comfort in use. BRIEF DESCRIPTION OF THE DRAWINGS
