Abstract (en)
[origin: EP0336288A1] The chair frame is composed of a seat part (5) and a backrest part (6). Adjoining the knee-side end of the seat part (5) is a flexible spring joint (10) which is attached to the free end of a bearing arm (2) by means of a hinge (11). Attached to the backrest part (6) is a backrest strut (15) which is mounted by means of a hinge (18) on a slide (20) which is guided displaceably in a bearing arm (2). Mounted in the bearing arm (2) is a compression spring (24), one end of which is connected to the slide (20), whereas the other end is mounted by means of a hinge (25) in the side walls of the bearing arm (2). Adjoining the knee-side flexible spring joint (10) is a lever (12), on which an adjusting screw (13) is arranged, with which the prestress of the knee-side flexible spring joint (10) can be adjusted. The chair frame is simple compared to known designs and requires only one small compression spring (24). <IMAGE>
