The present invention relates to a chair, and more particularly, to a chair having a hollow decorative member coupled to a part of the back such that the viewer feels aesthetics in harmony with the space used.

In general, in modern life, chairs are used almost daily, and sofas or armchairs for comfortable rest, classroom chairs used by students in classrooms, study chairs used in homes, and office workers in various companies. Various types of chairs are used very closely with daily life such as office chairs used, chairs used as seats in various means of transportation such as buses and trains, and chairs provided for passengers to rest in parks and bus stands.

In addition to improving the standard of living, poor sitting posture or sitting in an uncomfortable chair for a long time puts a strain on the user's spine and makes the user feel tired easily and further causes pain in the neck, lower back or buttocks, With repeated health problems, such as neck and lumbar disc disease, which are repeated, modern health-conscious people are increasingly interested in proper sitting postures and chairs that are desirable for spinal health. It is increasing.

Therefore, it is a general selection criterion to consider not only the purpose of seat selection as a means of sitting but also a matter of comfort when sitting, especially office workers who spend much of their day sitting on the chair. For workers and students, the functionality related to the improvement of office work efficiency and learning efficiency is an important consideration along with the comfort of sitting.

According to the demands of the consumers, technicians designing office chairs or learning chairs have introduced ergonomic design techniques, and thus, beyond the degree of sufficient use of cushion members, the expected body structure and working load of the target user are expected. In view of the back, the optimized chair design is generally applied. For example, the seat plate in contact with the buttocks at the time of seating is designed in consideration of the three-dimensional shape of the buttocks, and has a lumbar support function that supports the lower back so as not to burden the spine, and a headrest that supports the head portion. In some cases, various ergonomic design techniques are generally attempted, such as designing the backrest in a form capable of active load support in consideration of the three-dimensional shape of the back portion.

On the other hand, in recent years, the chair is not satisfied with comfort and functionality through ergonomic design, and the importance of the design is emphasized in consideration of the harmony with the surrounding space used from the interior point of view, and thus various forms of decoration It is easy to see that the elements are provided in the chair. Such decorative elements are provided with functional elements, which provide psychological comfort to people living for a long time in a limited space, and thus have a desirable effect such as improving working and learning motivation.

As an example, in the case of an office chair, a metal pipe such as stainless steel may be used as a decorative member to emphasize a simple, modern and urban image.

1 is an exploded perspective view showing a chair having a decorative member according to the prior art, Figure 2 is an exploded perspective view showing a back portion of the chair having a decorative member of FIG.

Office chair having a decorative member according to the prior art as shown in Figure 1, by injection molding a plastic material through a metal mold or press-molded metal material to form a frame 110 for seat plate, the plastic material to mold Through injection molding to form a back frame 120, the seat cushion member 130 and the back cushion member 140 with a cover made of a material such as fabric or leather, respectively assembled with the corresponding frame seat and backrest Combining the support legs 150, including wheels for moving to the seat plate, and through the series of processes connecting the seat plate and the backrest to the 'L' shaped elastic support member 160, the basic form is added in this state In general, the rear side of the back portion is provided with a decorative member 100 in the form of a metal pipe.

The decorative member 100 according to the prior art as described above, as shown in Figure 2, once the decorative member in the plurality of semi-open seating grooves 121 formed when injection molding the frame 120 for backrest ( In the state in which the corresponding portions of 100 are positioned, the semi-opening fixing members 125 of the shape corresponding to each semi-opening seating groove 121 are superposed, and the surface contact with each other using a fastening means such as a screw 127 or the like. It is coupled to the backrest of the chair as a structure for fastening the peripheral portion of the fixing member 125 and the seating groove 121 overlapped in the state, and combined by blocking each open end of the decorative member with a plastic cap 170. You will finish.

However, in view of the design aspect, such a coupling structure, unlike the original intended due to the exposure of the decorative member provided in the chair is exposed to the fixing member used for fixing and the screw used as a fastening means in some cases There is a problem that may cause discomfort to the user, and furthermore, there is a problem of a decrease in productivity and a cost increase due to the addition of a manufacturing process due to the handling of a plurality of parts in connection with the decoration member.
