[0097] The same reference numbers are used for identical and similar parts in the subsequent description.

[0098] FIG. 1 shows an oblique view of a child seat system comprising a base 10 and a seat element 11a or 11b (indicated schematically), on which a child 12 can sit. The seat element 11a is configured for a larger child than the seat element 11b. The base 10 has a plinth element 13 as well as a rotary element 14, which can be rotated with respect to the plinth element 13. The rotary element 14 can, in principle, (depending on the conditions subsequently described in detail) be rotated at a 360 angle with respect to the plinth element 13 (about an at least substantially vertical rotational axis). The base 10, preferably the rotary element 14, has a fin 15, which protrudes upwards from the base 10, preferably from the rotary element 14. The fin 15 is designed such that it appropriately supports and stabilizes at least one seat element, which can be mounted on the base, for example a baby seat, such that a carrying structure of the seat element 11 is provided at least partially by the fin. Weight can thus be saved on the part of the seat element 11.

[0099] The base 10, in particular the rotary element 14, has fastening devices 16a to 16d. The fastening devices 16a, 16b can, in this case, accommodate a bar provided on the seat element 11a/11b. The fastening devices 16c, 16d too can accommodate a bar provided on the seat element 11a/11b, such that the seat element 11a/11b can be mounted on the base 10, in particular on the rotary element 14. In this case, only one type of mounting is preferably possible for all seat elements 11a/11b provided for the base 10, in which mounting the child is looking away from the fin 15. It would alternatively also be conceivable that owing to the fastening device 16a, 16b on the one hand, and 16c, 16d, on the other hand, a mounting rotated about 180 is allowed (in particular the fin 15 can then possibly also be dispensed with).

[0100] Since the fastening devices 16c, 16d are designed directly adjacent to the fin 15, the seat element 11 can correspondingly abut the fin (in particular its rear wall). Alternatively, the fin can also be inserted into the seat element (in particular a rear wall) and thus bring about its stabilizing effect.

[0101] The fin 15 is preferably in direction contact with a seat element 11 (for example, baby seat) over at least 10 cm.sup.2, further preferably at least 20 cm.sup.2, if it is mounted.

[0102] The fin 15 can be oriented at least substantially vertically, in particular at an angle of no more than 30, further preferably no more than 20 with respect to the vertical. In so far as the orientation fluctuates, an orientation that arises through a connecting line between the upper and lower end of the fin should, in this case, in particular be valid.

[0103] The fin can extend in a (slightly) arcuate fashion, in particular in order to be as well adapted as possible to a likewise (slightly) arcuate outer wall of the seat element.

[0104] Furthermore, the fin 15 has lateral projections 17a, 17b and upper projections 17c, 17d. These projections are preferably connected to one another (in the inside of the fin), but are preferably able to move with respect to the fin 15 (i.e. are also moveable with respect to the base 10).

[0105] The projections 17a to 17d preferably allow in an (upper) position a complete rotation of the seat and in a second (lower) position only one rotation from at least a backwards facing position of the seat into an entry and exit orientation (rotated by 90). Alternatively, a complete blocking of the rotation can also be possible in this case.

[0106] If a seat element (e.g. baby seat), in particular in a potentially only possible (backwards facing) configuration with respect to the base, presses on the projections 17c, 17d, a rotation can be blocked. At the same time, an installation of the seat element (of the baby seat) in the forwards facing state can be effectively prevented, as the projections cannot be transferred into the second position and the seat element (baby seat) cannot as a result be moved sufficiently far downwards, in order to cooperate with locking devices (to be described below) of the seat element with respect to the base. However, another seat element can cooperate with the projections 17a, 17b, which can be pressed down by corresponding elements of the further seat element, for example if the headrest or a button (etc.) is moved into a corresponding position.

[0107] A support foot 18 can further be arranged on the base 10, in particular on the plinth element 13.

[0108] In the configuration according to FIG. 1, a first seat element can in particular be mounted (in the forwards orientation), but a second seat element cannot, wherein the second seat element is preferably a baby seat and the first seat element a group II/III child seat. The second seat element (baby seat) is (also), in contrast, able to be mounted in a position of the rotary element 14, rotated by 180, with respect to the plinth element 13.

[0109] Mechanisms for locking the rotary element 14 with respect to the plinth element 13 are subsequently described.

[0110] For this purpose, locking elements 18a, 18b (see FIG. 1, enlarged for example in FIG. 2) are initially provided.

[0111] These can, on the one hand, be operated by means of a manual operating device 19, in particular comprising a button 20 as well as a slider or puller 21, wherein corresponding movements are indicated by arrows 22, 23 (see FIG. 3).

[0112] It can be seen in FIG. 4 that pulling/sliding on the slider or puller 21 has the effect of a hook-shaped oblique element 24 pressing against a pin 25 of the locking element 18b from below. As a result, a locking hook 26 of the locking element 18b rotates from a corresponding recess (which cannot be seen in detail in FIG. 4) on the plinth element 13. Since the locking element 18a is connected to the locking element 18b via a bar 27, the locking element 18a also rotates automatically out of its locked position and the rotation of the rotary element 13 with respect to the plinth element 14 is enabled. This enabling can similarly also be performed by means of a (mirror-inverted) operation of a manual operating device 19 (located opposite the manual operating device 19).

[0113] An alternative operation for the locking devices 18a, 18b can take place such that a seat element (in particular a group II/III child seat) presses against a lever arm 28 (see FIG. 5), in a specific configuration of the seat element, such that by moving the lever arm 28 (in FIG. 5 a pivot to the left) the locking hook is led out of the recesses 29 which can be seen in FIG. 5. In this case, the seat element can, possibly at the same time, act on both locking elements 18a and 18b (designed similarly or mirror-inverted). However, owing to the bar 27, acting on just one of the locking elements 18a or 18b also possibly suffices.

[0114] As can be seen in FIG. 1, the rotary element 14 has a cover 29. An (in particular metallic) inner construction of the rotary element 14, which in particular comprises an inner construction of the fin and an inner construction of the remaining components of the rotary element, can be provided.

[0115] Further views of the base according to the invention are shown in FIGS. 6 to 15, wherein here the cover parts, in particular the cover 29 have been removed.

[0116] The seat base 10 is shown in a forwards orientation in FIG. 6, wherein the locking elements 18a, 18b are in a locked state. One of the locking elements, namely the locking element 18a, can be seen in the detail view according to FIG. 7. An optional slot-like hole 30 can further be seen, which, however, is merely a component of an optional screen 32, which rotates together with the entire rotary element 13. The actual counter structure is a hole (concealed by the screen) in an underlying ring 31.

[0117] The locking elements 18a, 18b can be seen again in FIG. 8, wherein here too the screen 32 (as an in particular cross-shaped element) can be seen.

[0118] FIG. 9 shows a view similar to FIG. 8, but from another perspective.

[0119] FIG. 10 shows a further overview of the base 10 according to the invention (without covers) in an entry and/or exit orientation, wherein the locking elements 18a, 18b are in the unlocked state.

[0120] A pin 33, which forms a soft lock in the configuration according to FIG. 10, can be seen in FIG. 11. It can be seen that an (upper) surface of the pin 33 is rounded, such that the setting (soft lock) can be overcome by lateral forces (as a result of a rotation of the rotary element 14 with respect to the plinth element 13).

[0121] The locking element 18b can be seen in an unlocked state in a detail view according to FIG. 12. Although the locking element 18b preferably engages through the screen 32, it rests on the ring 31. In comparison to FIG. 7, the locking element 18b is considerably pivoted.

[0122] FIG. 13 shows an overview of the base 10 in a backwards orientation, wherein the locking elements 18a, 18b are in a locked state.

[0123] FIG. 14 shows a detail view from FIG. 13, namely the locking element 18b in a locked position.

[0124] FIG. 15 shows a view similar to FIG. 14, wherein in contrast to FIG. 14 the locking element 18b is in a (significantly) unlocked position and enables the view on the counter structure (the hole in the ring 31 below the screen 32).

[0125] It should be noted at this point that all the above-described parts by themselves and in any combination, in particular the details illustrated in the drawings, are claimed to be essential to the invention. Modifications therefrom are common for a person skilled in the art.
