The backrest of a chair comprises an inner low rigidity flexible back-receiving portion and an outer high-rigidity side frame spaced from the back-receiving portion via a slit. The backrest is integrally molded by synthetic resin, thereby shortening manufacturing process and reducing its cost. Comfort of a sitting person is also attained.

Backrest of a chair

Chair

A chair comprises a back cushion material, a back plate and a back frame. The chair is used for looking at a display of a personal computer at suitable posture when it is reclined. The back plate comprises upper and lower shell which are connected by a flexible bent portion to each other. The back plate is mounted to the back frame at the upper end and a lower portion. When the chair is reclined, the upper shell is moved forwards and the lower shell is moved rearwards, so that an angle between the upper and lower shells may become smaller. Thus, the operator can take suitable posture for looking at the display any time.

To save space in an office when a personal computer is operated or when a conference is held with a number of persons, a working table which has a concave portion at the front edge and a auxiliary table are used. A plurality of the working tables and auxiliary tables are arranged side by side and surrounded by a partition to form a working room. The auxiliary table is placed by the working table and is movable with casters at the ends of feet of the auxiliary table. The height of the auxiliary table is variable, so that it is disposed with the working table at the same height for conference in the office, or is stored under the working table when the auxiliary table is not used. On a board which is slidably mounted on a panel at the rear end of the table, information or schedule may be written. The working room surrounded by the partition has a roll screen, and the workers can discuss various matters, watching an image on the roll screen projected by a projector.
