Abstract
In this chair a rounded spring element (128) formed with substantially U-shaped cross-section is provided which comprises parallel legs and with which a seat area (130) and/or a back (142) can be integrated. The spring element consists of plastic and is made single-walled in the curvature region, then dividing in the direction of the seat area and the back into a double-walled form. For reinforcement, ribs (148) may also be provided. At the lower side of the seat area and the double-walled portion of the spring region (128) an integrated socket for a support frame is formed. On the seat area (130) a cushion (174) may be secured with the aid of a stirrup member (136) driven into sockets (140) and comprising wood or steel tube or integral foam. The back consists for example of a cushion support (142) to which a cushion (144) is secured via a stirrup member (146) driven into sockets (152) on the spring region. It is possible to make the spring region (128), seat area ( 130) and back (142) from uniform material. Arm rests may be secured to the stirrup members of the cushions.
