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 ). |
