Title: Backrest tilting chair
Inventor: KIM TAE OOK
IPC: A47C7/44
Filed: 2019-10-04
Abstract: The present invention relates to a chair used widely in an office, a house, a school and the like. More specifically, the bottom of a backrest body is formed to be combined with one side of a lower part of a seat, and the bottom of a supporter combined with a rear side of the backrest body is combined with a tilting device, wherein the backrest body is constituted such that a fixing support part on a lower side, a lumbar support part in the middle and a load support part on an upper side are formed into a spinal curve shape of a human body. Therefore, when a user is leaning back to take a rest, unlike an existing chair, the backrest does not move backward and turn but only an upper part of the backrest body is bent back to lead a lumbar part of the user and the lumbar support part of the backrest to continuously maintain a tight-contact state, thus enabling the backrest body and the spinal curve to be bent back in tight contact with each other even if the user does not adjust his or her posture or move, which can lead to excellent user convenience and comfort. Moreover, since a curve shape of the lumbar part by the leaning-back and a curve of the lumbar support part of the backrest body are matched with each other, even if the user uses the chair bent for a long time, the lumbar part of the user can be effectively supported and borne, which can lead to use in a more comfortable and cozy state.
