of the folding lever 28 having its pin 34 guided in the oblong hole 32 comes into contact with the front end section of the oblong hole 32 and or strikes thereon because of this displacement limiting and due to the front rocker 24 a further propulsion movement of the backrest 12 is converted nearly completely into a pivot movement of the seat part 10 directed forward and downward in addition to this positive guiding function the oblong hole 32 allows a translational displacement of the seat part 10 between its basic position shown in fig6 and the first folded position illustrated in fig7 the leg spring which is situated in particular in the area of the linkage 38 counteracts a possible dead center position of the pivot mechanism and provides a spring force which supports the actuation of the pivot movement the vehicle seat is provided in particular as part of a rear bench seat of a passenger automobile it is particularly conceivable for this purpose to divide the entire rear bench seat into three or two modules for example in the ratio 40 20 40 or the ratio 60 40 each individual submodule being able to have a separate pivot and folding mechanism shown here in the second folded position of the vehicle seat in fig5 the seat part 10 at least regionally plunges into a foot space provided behind a front seat 40 so that.
