Assembly for chair and chair including the same

Abstract

An assembly for a chair and a chair including the same are provided. The assembly includes a body coupled to an upper portion of a leg of the chair, a pair of supports extending forward from opposite sides of the body and coupled to a bottom surface of a seating part, and a pair of connecting frames extending backward from the opposite sides of the body, bent upward, and shaft-coupled to the opposite sides of the body and the seating part. A tilting operation is performed to rotate downward the seating part and a backrest to adjust inclinations of the seating part and the backrest using a weight of a user applied to the seating part and elastic force of the support and the connecting frame.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to an assembly for a chair and a char including the same. More particularly, the present invention relates to an assembly for a chair, capable of tilting a seating plate forward or backward using elasticity of a support to support the seating plate, and a chair including the same.2. Description of the Related Art[0002]A chair, which includes a seating plate, a leg, or a backrest, is used for a user to allow the user to sit and perform various tasks. In the situation that the user has to sit for a long time, the selection of a chair appropriate to the user is important. To this regard, the chair has a function of adjusting the height of the seating plate or the angle of the backrest. Nevertheless, when the user is seated on a chair for a long time, the user has a fixed posture, the pain or the deformation of the physical body of the user may be caused. Accordingly, there has been developed a chair...

AI Technical Summary

Benefits of technology

The present invention aims to provide an assembly for a chair that is easy to assemble, can perform titbling operations in both the seating part and backrest, reduces the number of parts needed, and is slim in size. The invention achieves this by removing parts like torsion bars or springs that were previously necessary for titbling operations, resulting in improved workability and reduced manufacturing costs. Additionally, the structure of the assembly is simplified, allowing for a slim and efficient chair design.

Problems solved by technology

Nevertheless, when the user is seated on a chair for a long time, the user has a fixed posture, the pain or the deformation of the physical body of the user may be caused.

However, according to patent documents 1 to 3, as only the backrest is tilted forward or backward in the state that the seating plate is fixed, the user effectively fails to tilt the seating plate and the backrest suitably the body shape or the posture of the user.

Therefore, according to the assembly for the chair of the related art, the structure may be complicated, and the workability may be degraded in the work of manufacturing the assembly for the chair, and the manufacturing cost may be increased.
