[0060] FIG. 2 a headrest of the child seat from FIG. 1;

[0061] FIG. 3 sections of the headrest according to FIG. 2 with a locking mechanism in a locked position;

[0062] FIG. 4 the sections according to FIG. 3 with the locking mechanism in the release position;

[0063] FIG. 5a-5d a movement cycle of parts of a locking according to the invention;

[0064] FIG. 6 an alternative embodiment for the section according to FIG. 5a;

[0065] FIG. 7 a further alternative embodiment for the section according to FIG. 5a;

[0066] FIG. 8 a further alternative embodiment for the section according to FIG. 5a.

[0067] In the following description, the same reference numbers are used for identical and identically acting parts.

[0068] FIG. 1 shows a child seat (specifically a baby seat) with a locking mechanism according to the invention for adjusting the headrest position (or height of the headrest). The locking mechanism itself can not be seen in detail. The child seat has a main body 10 (first part) as well as the headrest 11 (second part).

[0069] FIG. 2 shows the headrest 11 of the child seat according to FIG. 1, wherein the headrest 11 comprises a support 12 for the child's head, which can usually be covered by a padding (not shown) and/or a cover. The headrest 11 comprises an actuation device 13 (with an actuation handle at its upper end). The actuation device (the actuating element) 13 may (as here) be integrally formed with an optional pulling element (pulling section) 14. Alternatively, a design with separate elements is also possible.

[0070] The pulling element (the pulling device) 14 can be connected (preferably, as shown in FIG. 2, at its lower end) to an adjustment device (adjustment element) 15, so that an actuation of the adjustment device 15, in particular a pulling upwards (or along the support 12) and away from the adjustment device or at least from one locking device (hereinafter always referred to as upwards), drives the adjustment device 15 to also move upwards. Furthermore, at least one locking device 16 (here specifically exactly two locking devices 16) is provided, wherein a respective locking device 16 optionally has a latching element 17 and possibly a lug 18.

[0071] FIG. 3 shows parts of the headrest 11 from FIG. 2 with a locking mechanism in a locked position. An adjustment slide 19 is provided (which can be, for example firmly, connected to the support 12, for example screwed and/or glued and/or connected by means of snap hooks). A spring device 20 is assigned to the adjustment device 15. Furthermore, the adjustment device (the adjustment element) 15 is guided in the adjustment slide 19 so that it can be pulled upwards.

[0072] Alternatively or additionally, other spring devices (spring mountings) can also be used, for example the actuation device (the actuating element) or the pulling device (the pulling element or the pulling section) can be spring-mounted, and/or the respective locking device (e.g. relative to the adjustment slide and/or relative to each other) can be spring-mounted.

[0073] Instead of the helical spring (shown) (compression spring), one or several other spring(s) can also be provided.

[0074] The adjustment device (the adjustment element) can, in particular at its lower end, encompass a lug 18 of a (respective) locking device with two lateral arms 21 each.

[0075] The safety can be increased by a double (encompassing) design of the arms. However, this is only optional for realising the locking mechanism according to the invention, since one arm (per side) is also sufficient or a still different structure is possible.

[0076] Even more generally, for example, only one locking device is necessary to realise the locking mechanism. Advantageously, however, two locking devices (in particular mirror-symmetrical, as shown in the figures) are provided to further increase the safety. However, the preceding and following remarks on the locking device per se are also advantageous if only one locking device is provided.

[0077] The (respective) arm 21 can have a recess (hole) 22, which is suitable for receiving a (respective, shown dashed in FIG. 4) pin of the pulling device 14 (of the pulling section). Furthermore, the (respective) lug 18 can have a second ramp 23, wherein the (respective) lug 18 in the embodiment shown (which is not mandatory) further has webs 24 for stabilisation and better guidance, which together with the second ramp form an (at least approximately) triangular recess 28, which is also penetrated by the pin 27. The arrangement shown can be varied in a simple manner, for example the adjustment device (the adjustment element) can be formed on each side with only one arm and pins provided on these, for example pointing forwards, whereby the pulling device (the pulling element) or the pulling section can then have receiving holes for the pins 27.

[0078] The pins 27 can interact with the (second) ramps 23 in such a way that an upward movement of the pins drives the (respective) locking device to move inwards from a locking position into a release position. The adjustment device 15 can also have at least one (first) ramp 25, specifically (optionally) a right and left first ramp 25. These can be designed to co-operate with internal heads 26 of the respective locking device in order to drive the latches from their release position back into the locking position after the actuation under the tension of the spring device 20 has ended.

[0079] Here, the second ramps 23 can define the above-mentioned second control sections (and thus also the release segment explained above), and the heads 26 can define the fourth control sections. The pins can define the first control sections and the first ramps 25 the fourth control sections (and thus in particular also the blocking segment explained above).

[0080] FIG. 4 shows the arrangement from FIG. 3, but now in the release position. The (respective) locking device (locking element) is moved inwards so that it no longer engages in a corresponding locking structure (not shown) (e.g. recess and/or hole).

[0081] FIGS. 5a-5b show a (complete) movement cycle of parts of a locking structure according to the invention. In particular, an adjustment device 15 (adjustment element) with a receiving hole for a pin 27 (first control section) with a first ramp 25 (fourth control section) as well as a locking device (locking element) with a second ramp 23 (second control section) and a head or corresponding projection 26 (fourth control section) are shown. The pin 27 can also be an (integral) part of the adjustment device, whereby a potential pulling device can also be attached to the adjustment device in another way. Furthermore, a unit comprising adjustment device and pulling device can also be understood as (multi-part) adjustment device.

[0082] FIG. 5a shows the beginning of an actuation of the (not shown) actuating element (actuation device, whereby this can be a part of the adjustment device and/or pulling device), i.e. still the locked position. The pin 27 (directly) abuts the respective second ramp 23, while the head 26 and first ramp 25 are slightly spaced apart. Such a (comparatively small) distance is preferable, but not mandatory. The respective end points of the release segment and blocking segment are emphasised by dots. It can be seen that the release segment and blocking segment are the same length and parallel to each other. However, deviations from this are comparatively easy to realise by design (and are included by the disclosure). An engagement structure 29 (e.g. comprising a recess and/or a hole and/or a protrusion and/or a pair of protrusions) is also shown schematically, whereby preferably not just the one engagement position shown, but at least two engagement positions should be realised.

[0083] FIG. 5b shows the elements of FIG. 5a, but now in the release position or when the actuation device (not shown) is permanently actuated. The (respective) pin 27 has moved relative to the second ramp 23 from one end point of the release segment to the other end point. The latch 17 is no longer in engagement with the engagement structure.

[0084] FIG. 5c shows the elements from FIG. 5b, but after (just completed) ending of the actuation. The adjustment device (the adjustment element) has overcome the spacing under the spring force of a spring device (not shown), so that the head 26 is now in contact with the first ramp 25, while pin 27 and second ramp 23 are now slightly spaced apart.

[0085] FIG. 5d shows the elements from FIG. 5c, but now again in the locked position. The adjustment device (adjustment element) 15 has moved all the way down (in the figure) under the spring force of the spring (not shown), so that the locking device 16 has been driven or transferred into the locking position via the head 26.

[0086] FIG. 6 shows an alternative to FIG. 5a, in which both ramps 25, 23 are curved in the same direction. The respective end points of the release segment and locking segment are emphasised by dots.

[0087] FIG. 7 shows an alternative to FIG. 5a, in which both ramps 25, 23 are curved in the opposite direction. The respective end points of the release segment and blocking segment are highlighted by dots.

[0088] FIG. 8 shows another alternative, in which the adjustment device 15 (the adjustment element) has a first ramp (first control section) 25, which defines the release segment and interacts with a pin (second control section) (shown by the circle) of the locking device 16 (the locking element). Furthermore, the adjustment device (the adjustment element) has a head (third control section) 26 which co-operates with a second ramp (fourth control section) 23 of the locking device (of the locking element).

[0089] FIGS. 9-11 show a further alternative, whereby initially in FIG. 9 an adjustment device 15, a locking device 16 and an engagement structure 29 are shown separately from one another. The locking device (latching device) 16 has an elevation 30 (e.g. pointing out of the image plane) in the form of an inclined block. This block defines with its two long sides two ramps 25, 23, which can act as second and fourth control sections 25, 23 (here: rail control section). The adjustment device 15 has two pins (e.g. projecting into the image plane) or receiving holes for such pins, which can act as first and third control sections 27, 26.

[0090] FIG. 10 shows the elements shown in FIG. 9 in the locking position of the locking device 16. There, the third and fourth control sections 26, 25 are shown in contact, which may be existent, for example, due to a spring device (not shown) driving the adjustment device (the adjustment element) 15 downwards.

[0091] FIG. 11 shows the elements shown in FIG. 9 in the release position of the locking device 16. There, the first and second control sections 27, 23 are shown in contact, which may be existent, for example, due to an external (possibly manual) application of force via an actuation device (not shown) and against the force of a spring device (not shown) driving the adjustment device (the adjustment element) downwards.

[0092] Of course, with knowledge of the embodiments shown, it is also possible to provide two rail control sections on the adjustment device (on the adjustment element) and two running control sections on the locking element.

[0093] At this point, it should be noted that all the parts or functions described above are claimed to be essential to the invention when viewed in isolation and in any combination, in particular the details shown in the drawings. Modifications thereof are familiar to the skilled person.

[0094] Furthermore, it is pointed out that the broadest possible scope of protection is sought. In this respect, the disclosure contained in the claims can also be specified by features that are described with further features (even without these further features necessarily being included). It is explicitly pointed out that round brackets and the term in particular are intended to emphasise the optionality of features in the respective context (which does not mean, conversely, that a feature is to be regarded as mandatory in the corresponding context without such identification).
