[0005] The furniture can be sofas, sofa beds, chairs, etc. As shown in the picture, the backrest protrudes from the support and rests on one side of the top of the seat, making it less likely to tip over forward or backward or shift vertically, effectively ensuring structural stability and reliability. The outline of the first arc-shaped block smoothly transitions with the outline of the support, avoiding sharp joint surfaces and effectively reducing scratches, while also providing a pleasing appearance.

[0006] Furthermore, the first arc-shaped block includes a top surface and an arc-shaped surface. The top surface fits into the support portion, and the arc-shaped surface smoothly transitions into the outer surface of the support portion. The first arc-shaped block has a relatively smooth outer surface (i.e., the arc-shaped surface), and the entire arc-shaped block has a smooth shape, which can resist external forces and form a reliable anti-collision structure. The top surface fits into the support portion, forming a reliable connection.

[0007] Furthermore, a snap-fit ​​assembly is provided between the backrest and the seat. The snap-fit ​​assembly includes a U-shaped limiting member and a buckle. The backrest and the seat can be disassembled and assembled by separating and engaging the U-shaped limiting member and the buckle.

[0008] Furthermore, the furniture with the anti-collision backrest also includes an armrest disposed on the side of the seat, and the bottom of the armrest is provided with a second arc-shaped block, the contour surface of the second arc-shaped block smoothly transitioning with the contour surface of the armrest.

[0009] Furthermore, the armrest and the backrest are provided with a snap-fit ​​assembly, which enables the assembly and disassembly of the backrest and the armrest through the separation and engagement of the U-shaped limiting component and the buckle.

[0010] Furthermore, the U-shaped limiting member has a groove that is shallow at the top and deep at the bottom, and the buckle can be inserted into the groove to achieve limiting.

[0011] Furthermore, the U-shaped limiting member has a retaining edge and an arc surface, the retaining edge and the arc surface forming the groove.

[0012] Furthermore, the buckle has an insertion edge that is narrower at the top and wider at the bottom, allowing it to be inserted into the groove. The matching shape of the insertion edge and the groove effectively prevents the buckle from disengaging.

[0013] The beneficial effects of this utility model are as follows: This application relates to a piece of furniture with an anti-collision backrest, which has a first arc-shaped block, and the outline of the first arc-shaped block smoothly transitions with the outline of the support part, thereby achieving an anti-collision effect. In addition, a second arc-shaped block is provided at the bottom of the armrest, providing better anti-collision effect for the bottom of the armrest. Attached Figure Description
