The present invention relates to a backrest chair having an elastic part for increasing the elastic force supporting the backrest, fixing the backrest more firmly, and forming a neckrest to provide comfort to the user.

Generally, a chair consists of a seat part which a person sits, the leg part which supports a seat part from the lower side, the back part which supports a person's waist, the support part which supports a back part, etc.

However, the conventional chair is not emphasized much about the backrest structure that supports the back of the body by simply emphasizing the role of supporting the body.

However, recently, a new concept of chair is proposed to bend the backrest part to support the waist comfortably when the person is sitting for a long time, or to support the back of the person by separating the backrest into two parts. It is becoming.

The conventional detachable backrest is configured to fix two or more separate backrests to a chair support with screws, etc., and the backrest is fixed in a state that does not absorb the elastic force on the support, thereby providing comfort and comfort to the user. It does not provide a problem.

In particular, when the user is sitting in the chair for a long time, the removable backrest is formed over a relatively large area has a problem of providing a foreign object to the user.

In order to solve this problem, the present inventors have already applied for the 'elastic support member for the chair back'.

In the accompanying drawings, Figure 1 is a perspective view showing the installation state of the conventional elastic support member for the chair back, Figure 2 is a partially exploded perspective view of FIG.

As shown in FIG. 1, the chair described in the above invention comprises: a seat portion 4 for allowing a user to sit down, a central axis 3 supporting the seat portion 4, and the central axis 3. Leg 2 for branching and supporting in various directions, a backrest 6 drawn out to the rear surface of the seat portion 4 and supported by the support 40, an armrest 5 for placing an arm, and It consists of an elastic support member 10 fixed between the backrest 6 and the support 40.

As shown in FIG. 2, the fixing plate 20 supports the backrest 7 by being fastened to the coupling screw hole 7 of the backrest 6 by a fixing screw 30 fitted in a plurality of fitting holes 22. In the fixing plate 20, a plurality of rectangular insertion holes 24 are formed, and the support part 12 of the elastic support member 10 is inserted between the backrest 6 and the fixing plate 20 to provide an elastic protrusion ( 16) made contact with the support 40.

The elastic protrusion 16 is fixed by being fastened to the fastening screw hole 17 by the fastening screw 22 fitted into the through hole 42 formed in the support 40 after being inserted into the square hole 24. The support part 12 was fixed by fastening the screw 28 inserted into the fitting hole 26 of the fixing plate 20 through the fixing hole 14 and fastened to the fixing screw hole 8 of the backrest 6. On the upper side portion of the support part 12, a plurality of reinforcement parts 19 are formed in the longitudinal direction.

In addition, the elastic support member 10 has a wrinkle portion 18 is formed to exert an elastic force, the reinforcement portion 19 is formed to protrude into a hemispherical protrusion cross section, the elastic support member 10 is slightly It is made of a rubber material that is hard and can exhibit sufficient elastic force.

As described above, the previously applied 'elastic support member for the chair back' supports the user's waist while the wrinkles 18 of the elastic support member 10 are bent in a predetermined direction.

However, only the elastic support member of the conventional chair lacks the elastic force supporting the backrest, the coupling state of the backrest is not strong, there is a problem that does not provide convenience to the user.

As described above, the conventional backrest chair lacks a resilient force supporting the backrest, the coupling state of the backrest is not firm, and there is a problem that does not provide convenience to the user.

In order to solve this problem, it is necessary to increase the elastic force supporting the backrest and to make the backrest more firmly supported by giving an elastic force to the support for supporting the backrest.

Therefore, the present invention is intended to achieve the object by forming an additional elastic portion in the support in addition to the elastic support member for supporting the backrest, and also to form a neck rest, and to form an armrest to further secure the backrest.
