(9) FIG. 7 shows the pushchair seat according to FIG. 4 in a fourth position.

(10) In the following description, the same reference numbers are used for identical and equivalent parts.

(11) FIG. 1a shows a pushchair according to the invention (without upholstery). The pushchair includes a pushchair chassis 10 and a pushchair seat 11 (without upholstery). The pushchair chassis 10 comprises a frame-like construction and (in this case four) wheels 12, while the pushchair seat 11 is mounted on a bearing 13 (in this case comprising a horizontal strut or tube). From this bearing, the pushchair seat 11 can be removed (and repositioned, for example, rotated through 180°) so that both a forward driving position (as shown in FIG. 1a) and a reverse driving position can be set. Both the pushchair chassis 10 and the pushchair seat 11 are designed to be foldable (each separately). The pushchair chassis 10 can, for example, be folded in the same way as the printed publication DE 20 2017 100 792 U1. In concrete terms, this can be done by moving the front wheels towards the rear wheels so that they are close to each other (possibly arranged in a line). Furthermore, a distal slider section 14 can be pivoted in relation to a proximal slider section 15. A folded position is shown in FIG. 3.

(12) Furthermore, a backrest 16 of the pushchair seat 11 has a distal section 17 and a proximal section 18, wherein the distal section 17 can be pivoted in relation to the proximal section 18 (as explained in detail below) or is articulated to it. Furthermore, the pushchair seat 11 has a seating surface 19.

(13) As shown in FIG. 2, the distal section 17 can be pivoted (forward) in relation to the proximal section 18 of the backrest 16 until it rests against the proximal section in its end position (as shown in FIG. 2). At the same time (or partially overlapping in time), the proximal section 18 can pivot (backwards) relative to the seating surface 19, so that it assumes the position according to FIG. 2, in which it is (at least essentially) aligned parallel to the seating surface (but facing away from it).

(14) As can be seen in FIG. 3, the pushchair seat 11 is (completely) accommodated within a volume (defined by an envelope surface) of the pushchair chassis 10. Overall, a compact storage position can therefore be achieved.

(15) FIGS. 4 to 7 explain in particular how to move the pushchair seat from a usage position (according to FIG. 4) to a storage position (according to FIG. 7). In the position according to FIG. 4, a child could be accommodated and the pushchair used accordingly. To transfer the pushchair seat into the storage position according to FIG. 7, a (manual) actuating device 20 is first actuated so that a lock of the distal section 17 in relation to the proximal section 18 is released so that the distal section 17 can be pivoted in relation to the proximal section 18 (forwards by an angle ß.sub.1 with ß.sub.1<ß.sub.g, see FIG. 1a for definition of angle). As can be seen from FIGS. 4 and 5, the proximal section 18 initially remains in a constant position relative to the seating surface 19 (in which the proximal section 18 is locked relative to the seating surface 19). If the distal section 17, starting from the position according to FIG. 5, is now pivoted further relative to the proximal section 18 (forwards, by an angle ß.sub.1 with ß.sub.1 plus 32 at least approximately equal to ß.sub.g, see FIG. 1a for definition of angle), this pivoting movement releases the locking between the proximal section 18 and the seating surface 19, so that during a further pivoting movement (see FIG. 6) of the distal section 17 in relation to the proximal section 18, the proximal section 18 is also pivoted in relation to the seating surface 19 (backwards, by an angle Δα at least approximately equal to α.sub.g, see FIG. 1a for definition of angle). Overall, the distal section 17 is pivoted relative to the seating surface 19 by an angle Δγ at least approximately equal to γ.sub.g (forwards, see FIG. 1a for definition of angle). The final position is then shown in FIG. 7.

(16) Furthermore, FIGS. 4 to 7 show how the angle α between distal section 17 and proximal section 18 is successively reduced (starting from at least approximately 180°) (down to at least approximately 0° or an angle of at least less than 10°). Overlapping in time (in a period of time illustrated by the positions according to FIGS. 5 to 7), the angle ß between the proximal section and a plane defined by the seating surface is also reduced to 0° (at least approximately). The mechanism described in FIGS. 4 to 7 can also correspond to the mechanism described in DE 20 2017 100 792 U1 (there for the pushchair chassis). Other solutions are of course conceivable.

(17) The element 21 (see for example FIG. 4) may be a reinforcing element provided within an upholstery (not shown), which is therefore also pivoted together with the pivoting of the entire backrest. This element can also preferably have a distal element section 22 and a proximal element section 23 (see FIG. 4).

(18) It should be noted at this point that all the parts described above, considered in isolation, and in any combination, in particular the details shown in the drawings, are claimed to be essential to the invention. Modifications of this are familiar to the person skilled in the art.
