Abstract

The invention relates to a chair capable of adjusting the lumbar support force. The chair includes: a frame (110) supporting the back of a person sitting on the chair, and having a lumbar support unit (120) formed at a portion corresponding to a waist of the person; and a waist a pad (130) mounted to the frame (110) to be vertically movable, wherein when the lumbar pad (130) moves upward, the lumbar support unit moves forward or The lumbar pad (130) supports the lumbar support unit such that a human waist is stably supported by the lumbar support unit.

However, since the supporting member cannot adjust its position and supporting force, it is difficult to provide an optimal supporting force for a person sitting on the chair. [0004] In this regard, Korean Patent No. 1145613...
