Abstract

　A chair having a backrest (3) and a backframe (4) disposed behind the backrest (3). The backrest (3) is capable of being deformed in a bent manner by the body pressure from a seat occupant. The upper end part of the backrest (3) is attached to the back frame (4) by a first support device (12). Left and right end parts of the section of the backrest (3) at or slightly above the height of the waist of the user are attached to the back frame (4) by a second support device (13). The first support device (12) has a rigidity such that deformation in a bending manner occurs due to body pressure. The rigidity of the second support device (13) is higher than that of the first support device (12). The waist of the user is supported in a stable manner, and when rocking occurs, the upper end part of the backrest (3) is able to deform so as to follow the movement of the body. The backrest comprises a frame body (9) constituting the outer periphery of the backrest and a body support section (10) for receiving the body pressure of the seat occupant. The body support section (10) is divided into a center area comprising a group of laterally long center stays (41), and side areas comprising a group of similarly laterally long side stays (40). The center stays (41) and the side stays (40) are disposed so as to be vertically staggered. Stays (40, 41) that are laterally adjacent to each other are integrally linked by a linking piece (42) oriented at an incline.
