Description

a frame chair

technical field

The utility model relates to the technical field of furniture, in particular to a frame chair.

Background technique

Several of the most representative armchairs in ancient China, such as the four-head official hat chair, the male official hat chair and the rose chair, are all products of functionalism, which are the most in line with the modern ecological design concept and Original design with ergonomic principles. Their basic structure is an ultra-stable composite frame system consisting of a seat frame plus a quadruped and crossbar system, coupled with an exquisite and durable mortise and tenon structure system, making this armchair a model of modern functionalist design.

In daily life, frame chairs are relatively commonly used furniture. There are many styles of frame chairs, including basic components such as frames, support frames, seating surfaces, and backrests.

However, the existing frame chairs are relatively traditional, have a complex structure, cannot reach the best angle conforming to the principles of ergonomic design, and have insufficient comfort in use.

Embodiment one

Referring to Fig. 1 to Fig. 5, an embodiment of a frame chair provided by the embodiment of the present invention includes:

The basic parts of the frame chair of this embodiment are two independent side brackets 1, the seat surface 2 and the back surface 3. What the frame chair of this embodiment adopts is the combination structure mode of the above-mentioned components. The frame chair of the utility model embodiment Mainly used in meetings, restaurants, offices and other occasions.

As shown in Figure 1, the side bracket 1 is two independent brackets, the side bracket 1 is a vertical rectangle, the seat surface 2 and the back surface 3 are respectively located between the two side brackets 1, the seat surface 2 is inclined downward relative to the horizontal plane, and the seat surface 2 is inclined downward relative to the horizontal plane. The surface 3 is inclined backward relative to the vertical surface, and the angle between the plane where the seating surface 2 and the seat surface 3 are located is an obtuse angle. In this embodiment, the angle at which the seat surface 2 inclines downward relative to the horizontal plane is 2°, and the angle at which the rest surface 3 inclines backward relative to the vertical plane is 12°.

It can be understood that the side bracket 1 is not only an armrest, but also a bracket on which the seat surface 2 and the back surface 3 rely.
