[0057] FIG. 10 the detail according to FIG. 9 in a different position of the headrest.

[0058] In the following description, the same reference signs are used for identical and identically appearing parts.

[0059] FIG. 1 shows a side view of a child seat according to the invention. The child seat comprises a seat section 10, a backrest 11, an (optional) base 12 and a headrest 13. The headrest 13 is connected to the backrest 11. The backrest 11 has (optional) at least one (e.g. foldable) side impact protection element 14 and at least one backrest belt guide 15. The seat area 10 has at least one seat area belt guide 16.

[0060] FIG. 2 shows the headrest 13 and a section of the backrest 11 adjacent to the headrest 13 according to a first design of the child seat. The headrest 13 comprises a front headrest part 17, a rear headrest part 18, and a headrest belt guide 19 (which may be configured as a separate part or as part of the front part 17). The front headrest part 17 has side cheeks 17a (only one of which is shown in FIG. 2). Below the side cheeks 17a there are correspondingly (two) headrest belt guides 19 (whereby in the figures the front belt guide in relation to the drawing plane has been omitted).

[0061] A movable support element 20 is arranged in the backrest 11, which is mounted (height-) displaceable in relation to a main body 21 of the backrest. The support element 20 can be designed flexible (elastic). In concrete terms, the support element 20 can be moved up or down (inside or on the backrest) relative to the main body 21. This also allows the headrest 13 to be moved relative to the main body 21 of the backrest 11.

[0062] Furthermore, the headrest 13 is pivotably mounted to the support element 20 via a swivel bearing 22 (=third connecting device). Specifically, at least one swivel element 23a of a headrest inclination adjusting device 23 can be swiveled (rotated) about a swivel axis 22a of the swivel bearing 22 so that the entire headrest can be swiveled.

[0063] This is further illustrated in FIGS. 3 and 4. In FIG. 2, a head-backrest 24 of the headrest 13 is (approximately) parallel to the backrest 11. In FIG. 3, the head-backrest 24 (and thus the entire headrest 13) is tilted backwards (relative to the backrest 11). In FIG. 4, the head-backrest 24 or headrest 13 is tilted even further back. The configuration according to FIG. 2 can be selected, for example, when the child is awake. The configuration according to FIG. 4 can be selected especially when the child is resting. FIG. 3 is an intermediate position which represents a compromise between adaptation to a resting or active child as shown in FIGS. 2 and 4.

[0064] On and/or in the swivel bearing 22, a (not shown) locking device, such as a bolt (in particular a projection or pin), may be provided, which may, for example, cooperate with one or more groove(s) and/or recess(es) in the backrest to allow locking in different (at least two, preferably at least or exactly three) inclined positions.

[0065] FIG. 5-8 describe an embodiment which basically corresponds to the embodiment according to FIG. 2-4, but in particular without the above described locking device (not shown in FIG. 2-4) (which may however be provided) and with a further connecting device (in addition to the swivel bearing 22), namely a first connecting device 25.

[0066] The first connecting device 25 is connected to the backrest 11 at one end 26 (fixed position). At an end 27 opposite the end 26, the first connecting device 25 (see also FIG. 8) has locking positions (at least partially formed as locking recesses) 28 defined by locking teeth 29. The first connecting device 25 forms a corresponding first locking device (or part thereof). The locking positions 28 allow the reception of a locking rod.

[0067] The rear headrest part 18 has a sliding pin 31 that can slide in a (see FIG. 8) recess (link) 32 of the first connecting device 25. The sliding pin 31 preferably has a head 31a located outside the recess 32 to secure it (and thus also to further secure the connection between backrest and headrest). The recess 32 (link) can be a groove or slot. Furthermore, a recess (link) 33 (e.g. groove or slot) can also (alternatively or additionally) be provided in the rear headrest part 18, within which, for example, a pin or rod 34 (indicated by a dashed line in FIG. 8) can slide, thus creating a movable and yet secure connection.

[0068] In the area of the head-backrest 24 (see FIGS. 5 and 8), an actuating device 35 is provided which (preferably by pulling it upwards) causes the locking rod 30 to be lifted from the corresponding locking position 28 so that the inclination of the headrest 13 can be adjusted. The actuating device 35 preferably has an actuating handle 36 (in the form of a projection) for this purpose. By pulling (lifting) the actuating device 35, a locking can be released by the locking rod 30 so that the first connecting device 25 can be moved relative to the headrest 13. Furthermore, a recess (not shown in the figures) can be provided in the rear headrest part 18 in which the locking rod 30 can be moved and which can be aligned with (one) locking position 28 (in each case).

[0069] Preferably, the actuating device 35 can be shifted from a locked state to a released state against the force of a return device (in particular return spring) so that the locked state is assumed without actuation of the actuating device (automatically).

[0070] The condition shown in FIG. 5 can be locked by (exactly) one of the locking teeth 29 (which blocks movement of the locking rod 30 relative to the backrest) and a front end of recess 32 (see FIG. 8; which prevents movement of the sliding pin 31 away from the backrest). Similarly, the condition shown in FIG. 7 can be locked by exactly one (namely the rearmost) locking tooth locking rod 30 between two locking teeth 29.

[0071] FIGS. 9 and 10 show a further embodiment of the child seat (in details). The headrest 13 may have all parts and features of the embodiment as shown in FIGS. 2-4 and/or 5-8 (if applicable, without the locking devices described in connection with FIGS. 2-4 but not shown in detail and/or without the first connecting device as shown in FIGS. 5-8). Furthermore, the headrest 13 according to FIGS. 9 and 10 may have a second connecting device 37 which connects the headrest 13 and the backrest 11 as an articulated connection and has at least one joint 38 (between two joint elements 39a, 39b). The second connecting device 37 can be configured in such a way that it can lock the state according to FIG. 9 and/or the state according to FIG. 10 and/or one or more intermediate states. For this purpose, the second connecting device 37 may have a toggle lever mechanism, for example.

[0072] At this point it should be noted that all of the above described parts are considered to be essential to the invention when viewed on their own and in any combination, especially the details shown in the drawings. Modifications of this are familiar to the skilled person.
