Abstract (en)
[origin: WO2007073836A1] The invention relates to a backrest (8), in particular for an office chair (2), comprising a backrest shell support (10) and a backrest shell (12) which protrudes from the backrest shell support (10) in a curved manner. Said backrest shell (12) has an upper and lower securing area (14, 16), in addition to a plurality of flexible areas (20, 22) which are arranged therebetween. The backrest shell (12) is securely connected to the backrest shell support (10) in the upper securing area (14). In the lower securing area (16), the backrest shell (12) is connected to the backrest shell support (10) in such a manner that it can be displaced in the longitudinal direction (L), such that the curvature (18) of the backrest shell (12) modifies by means of the flexible areas when displaced. As a result, it is possible to adapt the contour of the backrest (8) to the shape of the human spinal column by means of a simple adjustment of the curvature (18).
