Document Type and Number:

WIPO Patent Application WO/2018/041256

Kind Code:

A1

Abstract:

A chair structure and a chair. The chair structure comprises: a base (1) configured as connected to a chair base component; a seat support element (2), the seat support element (2) being provided above the base (1), and the front part of the seat support element (2) being rotatively connected to the front part of the base (1) via a transition connecting rod (8); a chair back component (3), the chair back component (3) being rotatively connected to the rear part of the base (1) via pivots (6); and a lever driving element (7) connected between the chair back component (3) and the seat support element (2), the lever driving element (7) being rotatively connected to the rear part of the seat support element (2), and the lever driving element (7) being arranged roughly on a same plane with the seat support element (2). The chair back component (3), when rotating rearwards around the pivots (6) from an initial position, lifts up the rear part of the seat support element (2) in an obliquely rearward direction via the lever driving element (7) and, at the same time, lifts up the transition connecting rod (8) and the front part of the seat support element (2). The chair structure forms one quad-connecting rod-lever-connecting arm structure. During use, the base (1) remains fixed, a force that the human body applies to the chair back component (3) is transmitted and drives the seat support element (2) to implement lifting/lowering on the base (1), thus implementing forward or rearward tilting.
