[0133] In the following, the same reference numerals are used for the same as well as the same acting parts.

[0134] FIG. 2 shows a schematic diagram of a stroller 1 with two receiving units 20, 30 in oblique view. Four wheels 42 (two front wheels and two rear wheels) are mounted in the lower region of the frame 40 or stroller frame 40. A first adapter 50 and a second adapter 60 are fixed to the frame 40. Furthermore, in FIG. 2, a first receiving device 20 is coupled to the first upper adapter 50. The first receiving device is oriented in the direction of travel of the stroller 1. The second receiving unit 30 is coupled to the second, lower adapter 30. The second receiving device 30 is oriented opposite to the direction of travel of the stroller 1.

[0135] In FIG. 3, a schematic detailed view of an adapter connecting element 31 of the second receiving device 30 is shown. In this execution example, a protrusion 311 of the adapter connecting element 31 is formed as a rib extending approximately vertically with the chassis frame 40 of the stroller being ready for operation. The adapter connecting element 21 (not shown here) of the first receiving device 20 can be identical except for the rib missing there. Also conceivable would be an adapter connecting element 31 having a second rib (not shown) on the right side.

[0136] FIG. 4 represents a schematic detailed view of an adapter element of the first adapter 50. In this execution example, the first adapter 50 is preferably the upper adapter 50. Furthermore, in FIG. 4, the first recess 51 is formed as a groove. Furthermore, the first adapter 50 has a two recess 52, which in this execution example is also formed as a groove. Furthermore, the first adapter 50 has a contact surface (no reference sign). Thus, by means of the first adapter 50, a connection of the frame 40 optionally with the first or the second child receiving device 20, 30 (not shown) can be achieved.

[0137] In FIG. 5, a schematic detailed view of an adapter element of the second adapter 60 is shown. The second adapter 60 does not have any recesses. In this execution example, the second adapter 60 is the lower adapter 60.

[0138] In FIGS. 6a to 6b, a schematic detail view of an adapter element of a first adapter 50 is shown in different positions. In FIG. 6a, the first adapter 50 is shown fixed in a rear upper position. The first adapter 50 is attached to the strut 41 of the stroller frame 40 extending from the rear top to the front bottom. In FIG. 6b, the first adapter 50 is shown in an intermediate position. In FIG. 6c, the first adapter is fixed in a front bottom position.

[0139] FIG. 7 shows a schematic detailed view of an adapter connecting element 21 of a receiving unit 20 in an oblique view. In this execution example, the adapter connecting element 21 has a blocking element 201, which is formed as a pin that can be depressed against the force of a compression spring, which is not shown visibly. When the blocking element 201 is depressed, the blocking element 201 comes into contact with an element 202 of a tilt angle adjustment mechanism (not shown) such that tilt angle adjustment mechanism (not shown) is locked or blocked. The tilt angle adjustment mechanism is used to adjust the tilt angle of the child receiving device with respect to the horizontal.

[0140] FIG. 8 shows a schematic detail view of an adapter connecting element 21 of a receiving unit 20 in a sectional view. In FIG. 8, the blocking element 201 is shown in a depressed state, wherein the blocking element is pressed against a restoring force of a spring (not shown). The depressed blocking element (pin) is further depressed into a recess 203 of an element 202 of the tilt angle adjustment mechanism (not shown), so that the tilt angle adjustment mechanism (not shown) is locked or blocked.

[0141] The element 202 of the tilt angle adjusting mechanism is fixedly connected to the back section of the receiving device 20, and has only one recess (a hole) for cooperating with the pin. This one recess corresponds to the seat position of the allowable receiving device 20. In principle, two or three holes corresponding to the pin 201 for adjusting different tilt angles of the child receiving device are also conceivable.

[0142] In FIG. 9, a schematic detailed view of a seat section 22 of a receiving unit 20 is shown in an oblique view. Furthermore, FIG. 9 shows a switching element 24.

[0143] In FIG. 10, a schematic detailed view of a seat section 22 of a receiving unit 20 is shown in top view from below. Furthermore, FIG. 10 shows the switching element 24. FIG. 11 shows two different states or positions of the switching element 24.

[0144] In FIG. 12, a schematic detail view of a seat section of a receiving unit is shown in top view from below, where in particular the adaptive turntable can be seen in detail.

[0145] In FIG. 13, a schematic view of a stroller 1 with a receiving unit 20 is shown in oblique view.

[0146] In FIGS. 14 and 15, another example of a mechanism for adjusting the tilt angle between a back section and a seat section of a first receiving device in the form of a first seat unit (FIG. 14) and a mechanism for adjusting the tilt angle between a back section and a seat section of a second receiving device in the form of a second seat unit (FIG. 15) are shown schematically. The mechanism shown in FIG. 14 allows four different tilt angles, while the mechanism shown in FIG. 15 allows only three different tilt angles. Specifically, in FIGS. 14, 15, a type of tooth rim 70 may be associated with a seat section that is oriented substantially horizontally when assembled, while a complementary swing bearing 71 is part of a back section that is useably mounted relative to the seat section.

[0147] FIGS. 14, 15 each show a locking position between tooth rim 70 (with teeth 72 pointing radially outward or similar protrusions) and swing bearing 71 (here in the form of a flat ring with recesses 73 complementary to the aforementioned teeth 72).

[0148] For unlocking, the teeth 72 must be removed from the complementary recesses 73 so that the parts 70, 71 can then be pivoted relative to each other about an axis 74 defined by the hinge axis between seat section and back section. For this purpose, the tooth rim 70 is displaceable either radially with respect to the axis 74, i.e. in the direction of the arrow 75 in FIGS. 14, 15, or in the direction parallel to the axis 74 until the teeth 72 disengage from the associated recesses 73.

[0149] Locking takes place in the opposite direction after setting the desired tilt angle.

[0150] It should also be noted that in the embodiment according to FIG. 15, the two teeth 72 of the tooth rim 70 are of different readiness. In the same way, the swing bearing 71 also has recesses 73 of different widths, wherein the arrangement of these recesses 73 is such that, with the same number of recesses as in the design according to FIG. 14, only three instead of four different angular positions of the parts 70, 71 relative to one another are possible.

[0151] Accordingly, the tilt of the back section associated with the swing bearing 71 can then also be adjusted differently relative to the seat section in the first and second child receiving devices each in the form of a seat unit.
