ABSTRACT:
The invention relates to a backrest with a support area (71), at least one structure connected to the support area (71) or forming the support area (71), which structure (10) extends towards the top of the backrest from a first end region of the support area (71) to a second end region of the support area (71) and at the front has a tension element (49) and at the rear a pressure element (47). The tension element (49) connects the first end region (37) of the support area (71) to the second end region (38) of the support area (71) transmitting tensile forces. The pressure element (47) connects the first end region (37) of the support area (71) to the second end region (38) of the support area (71) transmitting thrust forces. Pressure element (47) and tension element (49) are in the extension direction non-displaceably connected to one another in the first and in the second end region of the support area (71). The tension element (49) and the pressure element (47) between the end regions (37, 38) are connected to one another in the extension direction displaceably against each other by means of the spacers (14) keeping the distance. The backrest has at least one bearing axis (43), with which it can be joined or is joined to a seat-back bracket at a distance from the first and from the second end region of the support area (71) between these end regions (37, 38).
