A piece of fitting means, which is arranged in a centric manner to the articulated axle (30) of the back rest joint (24) effects a connection between the back rest (22) and the seat frame (20). Furthermore, a lever (32) for an unlocking device for the tilting forward motion is provided at the back rest (22). The back rest joint (24) is arranged at the back rest (22) with both its arms in the state of completion of the back rest (22). A stop motion device (50) is arranged at the seat frame (20) for the fitting of the first arm (26) on one hand, and on the other hand a clamping piece (52). The clamping piece (52) can be moved between a clamping position, in which it is flexibly prestressed and in which it fixes the first arm (26) together with the stop motion device (50), and a position of release, in which the back rest (22) can be swiveled freely and without the operation of the back rest joint (24) toward the front. At the first arm (26), an unlocking lever (36) is arranged, a) which is movably connected with the lever (32) of the unlocking device for the tilting forward motion and which can be moved by the same from a position of rest into a position of unlocking, b) in whose area of motion the clamping piece (52) is positioned and c) which pushes the clamping piece (52) on the way to the position of unlocking into its position of release.
