Description

[0001] The invention relates to a child seat for mounting on a motor vehicle seat, in particular a child seat that can be folded between a use position and a storage position. Furthermore, the invention relates to a method for adjusting a child seat.

[0002] Child seats for attachment to a motor vehicle seat are generally known in the prior art. These child seats are usually not very compact and are often difficult to transport. Transferring a child seat from one motor vehicle to another can therefore be relatively cumbersome. Transporting a child seat, for example, when traveling on vacation without one's own vehicle and needing or wanting to take a child seat with one, is also difficult with a conventional child seat. Even when stowing the child seat, a conventional child seat takes up a comparatively large amount of space. EP 3 256 343 B1 discloses a child car seat with a seat and a backrest, which can have a folded position in which the seat is brought against the backrest to form a compact unit, and an unfolded position in which a child can be placed in the seat.

[0003] A disadvantage of previously known foldable child seats is that folding them is comparatively complicated and technically demanding. In particular, folding the child seat requires numerous manual steps to transfer the child seat from the unfolded position (the state of use, i.e., in particular, the state in which the child can be safely accommodated in the child seat) to the folded position (the state of non-use, i.e., in particular, the state in which the child cannot be accommodated, or at least cannot be safely accommodated, in the child seat). Furthermore, the inclination of the child seat in the use position cannot usually be adjusted.

[0004] Child car seats can be attached to the vehicle seat using an Isofix system to ensure quick installation and secure attachment of the child seat to the vehicle. The brackets of the Isofix system may be adjustable relative to a lower side of the seat element. In this case, the child seat requires a mechanism for securing the Isofix brackets and an additional mechanism for folding the child seat.

[0005] The object of the invention is to propose a child seat for mounting on a motor vehicle seat that allows simple yet safe use, in particular, easy transport, space-saving storage, simple handling during operation, and / or stable attachment in / on the motor vehicle. Furthermore, the object of the invention is to propose a corresponding method for configuring a child seat.

[0006] This object is achieved in particular by the features of claim 1.

[0007] According to a first aspect, the object is achieved in particular by a child seat for mounting on a motor vehicle seat, wherein the child seat has a backrest, a seat surface element, an actuating element and an operator which is movable between a first and a second position, wherein the backrest is pivotally connected to the seat surface element, wherein the first position is a locking position and / or the second position is a release position, wherein the operator is movable between the first and the second position by actuating an actuating element.

[0008] One advantage of this is that locking the seat element to the backrest is technically easy to release.

[0009] Locking is understood, in particular, to mean that the child seat is in a state in which the backrest either cannot be pivoted relative to the seat element or can only be pivoted over a partial range of a total (generally possible) pivot angle (possibly freely, as long as no external structure is in the way, such as a backrest of a vehicle seat). The partial range (partial pivot angle) can, for example, be at least 1%, at least 5%, at least 12%, and / or at most 45%, or at most 30% of the total pivot angle.

[0010] The actuating element is preferably a manual actuating element and / or comprises a handle and / or a finger grip.

[0011] The operator can be designed in one or more parts. The operator can be formed by a continuous structure or several separate structures. The operator can be configured and arranged such that it cannot be directly manually operated, but in particular (only) via the actuating element, which in turn can be manually operated.

[0012] To release the locking mechanism of the seat element to the backrest in order to pivot the backrest, preferably only one hand movement or a mechanically simple movement is required, which can be performed with just one hand by the user. The easy release of the locking mechanism of the seat element allows the child seat to be folded quickly and easily.

[0013] If only one hand is needed to release the locking mechanism of the seat element and thus fold the child seat, the risk of injury, particularly the risk of the user pinching and thus injuring fingers and / or a hand, is reduced. This increases the safety of using the child seat.

[0014] The child seat is particularly technically simple in design and technically easy to manufacture.

[0015] In addition, the movement for folding the child seat can be carried out particularly intuitively, so that even a user who is not familiar with the child seat can fold the child seat comparatively quickly.

[0016] According to one embodiment, by continuing to reduce the angle between the backrest and the seat element, the backrest can eventually touch the seat element, allowing the child seat to be folded in a space-saving manner. Thus, the child seat can be folded, in particular, by a single movement (continuing without reversing the movement).

[0017] The child seat may be provided with at least one, in particular two, anchoring arms, preferably two Isofix brackets. The Isofix brackets may be movably mounted (in particular, forward and backward) on a lower side of the seat element and / or within the seat element, wherein each bracket may be separately movable or rigidly connected to the other bracket. The Isofix brackets may be releasably fixable with respect to their position.

[0018] According to a second aspect, which can preferably be combined with the first aspect, the object is achieved in particular by a child seat for mounting on a motor vehicle seat, the child seat comprising: - a backrest (optional), - a seat element, wherein the backrest (if present) is preferably pivotally connected to the seat element, and - an actuating element, wherein the actuating element is configured to enable at least a first setting and a second setting.

[0019] The actuating element is preferably movable over a total movement range, which comprises at least a first and a second (different from the first movement range, possibly adjoining it) partial movement range,

[0020] The first adjustment is preferably (also or exclusively) enabled by a movement of the actuating element into the first movement range. Alternatively or additionally, the second adjustment is preferably (also or exclusively) enabled by a movement of the actuating element into the second movement range.

[0021] Preferably, i) the second adjustment is enabled only by a movement of the actuating element into the second movement range or at least (not yet) by a movement of the actuating element into the first movement range, and ii) the first adjustment is enabled both by a movement of the actuating element into the first movement range and by a movement of the actuating element into the second movement range.

[0022] Preferably, a transition from the first range of motion to the second range of motion, and / or vice versa, is only possible by overcoming a resistance that is increased compared to the resistance in the first and / or second range of motion (or by overcoming a soft lock).

[0023] Preferably, the first setting is an adjustment of the backrest, in particular an inclination position thereof and / or a folding state (wherein the adjustment is then in particular the transition from the unfolded to the folded state and / or vice versa) thereof, and / or the second setting is an adjustment of a seat anchoring device, preferably an Isofix anchoring device, for anchoring on or at (or in) the motor vehicle (or motor vehicle seat), more preferably a length thereof, or vice versa (so that the second setting relates to the backrest).

[0024] According to a third aspect, which can preferably be combined with the first and / or second aspect, the object is achieved in particular by a child seat for mounting on a motor vehicle seat, the child seat comprising: - a backrest, - a seat element, wherein the backrest is pivotally connected to the seat element, and - an adjustment mechanism for adjusting a (in particular the above) seat anchoring device, preferably an Isofix anchoring device, for anchoring on or at (or in) the motor vehicle (or motor vehicle seat), more preferably a length thereof, which is configured such that an inclination of the seat surface element can be adjusted by the adjustment mechanism, in particular in interaction with a backrest of the motor vehicle seat, wherein the backrest is preferably freely pivotable over at least a partial range of an entire pivoting angle until it abuts the backrest of the motor vehicle seat in use.

[0025] In general, and in particular according to the third aspect, the length of the seat anchoring device can be locked not only against further lengthening, but also against further shortening (i.e., in both directions, unlike, for example, a ratchet mechanism). This allows the seat inclination to be easily adjusted by adjusting the seat anchoring device, particularly if the inclination position has a certain amount of play (e.g., a pivot angle of at least 10° or at least 30°). A flatter inclination setting can then be achieved, for example, by increasing the length of the seat anchoring device, so that the backrest can pivot further backward until it abuts the backrest of the motor vehicle seat.

[0026] According to a fourth aspect, which can preferably be combined with the first and / or second and / or third aspect, the object is achieved in particular by a child seat for attachment to a motor vehicle seat, the child seat comprising: - a backrest, and - a seat surface element, wherein the backrest is pivotably connected to the seat surface element, wherein the backrest, in a first state of the child seat, is freely pivotable over only a partial range (partial pivot angle) of a total pivot angle in order to set an inclination (suitable for use of the child seat) (or to adapt it, in particular to the motor vehicle seat, in particular its backrest) and is foldable in a second state of the child seat (i.e., in the second state, is pivotable at least over that range of the total pivot angle which lies outside the partial range assigned to the first state> preferably, the backrest can be (freely) pivoted over the entire pivot angle in the second state).

[0027] In an optional folded (in the fourth aspect: third) state of the child seat, the backrest is preferably lockable (determinable) or locked relative to the seat element (in particular in such a way that it cannot be pivoted, possibly apart from a slight tolerance range, for example of less than 4° or less than 1°, for trouble-free realisation of the locking process).

[0028] The partial range of the total pivot angle preferably constitutes at least 5% or at least 15% and / or at most 60% or at most 45% or at most 30% of the total (possible) pivot angle. Alternatively or additionally, the partial range of the total pivot angle is defined by a preferably curved slot and / or a rail and / or a guide.

[0029] Alternatively or additionally, the partial area of ​​the total pivoting angle preferably forms at least 5° or at least 20° and / or at most 60° or at most 45° or at most 30°.

[0030] The total (generally possible) pivot angle is preferably at least 60° or at least 90° and / or at most 270° or 180° or at most 135°.

[0031] In one embodiment, the child seat can be folded between a use position and a storage position, particularly when the operator is in the release position. A use position is a position of the child seat in which the child seat can be attached to the vehicle seat and a child can be placed in the child seat (and safely accommodated there). Such a child seat enables a simple folding mechanism, making the child seat easy to fold. In the storage position, the seat element and backrest are close to one another or touching; in particular, the backrest can rest on the seat element, and the child seat can be transported or stowed away.The backrest and any side panels of the child seat can be designed so that they are flush with the seat surface when folded, keeping the child seat as small as possible. This allows the child seat to be folded compactly for space-saving storage.

[0032] In a further embodiment, the backrest and the seat element can be pivotally connected to one another via a guide mechanism (preferably elongated or defining a guide path), in particular comprising or formed by at least one rail system. This allows for better guidance of the backrest relative to the seat element during pivoting.

[0033] The actuating element and the operator can be arranged at a distance from one another, in particular on opposite sides of the seat element. Preferably, the actuating element is arranged (partially or completely in at least one use position) in the front region of the seat element, wherein the front region of the seat element is the region that, when the child seat is attached to the motor vehicle seat, is directed forward toward the driver's seat or front passenger seat (wherein the front region extends, in particular, from a front end up to 40%, preferably up to 25%, rearward - based on the total extension of the child seat from front to rear and in particular in the at least one use position).Alternatively or, preferably, additionally, the actuating element is arranged (partially or completely) in the center of the child seat, in particular the center of the seat element, in particular the front region of the seat element. A respective center is understood to mean, in particular, a region that is spaced from the respective (lateral or left and right) edges by at least 20%, preferably at least 30%, of the entire width of the referenced element (in at least one use state of the child seat).

[0034] Due to the arrangement of the actuating element in the front area of ​​the seat element, the actuating element is comparatively easily accessible and can be operated without any problem, even when the child seat is fixed on the vehicle seat.

[0035] Preferably, the actuating element is attached to the lower side of the seat surface element, wherein the actuating element can be arranged such that it is operable when the child seat is secured in the motor vehicle. Thus, the actuating element is easily accessible for securing or releasing the Isofix system and, for example, for folding the child seat while it is still in the motor vehicle (when the child seat is still anchored by means of the Isofix brackets). The lower side of the seat surface element is, in particular, the side that faces / points toward a seat surface of the motor vehicle seat when the child seat is secured in the motor vehicle.

[0036] Preferably, the operator is arranged in the rear region of the seat element, wherein the rear region is the region which touches the backrest of the motor vehicle seat when the child seat is attached to the motor vehicle seat.

[0037] In a further embodiment, the rail system can comprise a guide rail and / or an element that can be guided in and / or on and / or at the guide rail. Preferably, the guide rail is formed by the seat element and / or the guide element is formed by the backrest (alternatively or additionally (e.g., if multiple pairs of "guide rail-guide element" are provided): vice versa). This enables better, low-friction guidance of the backrest and the seat element relative to each other.

[0038] The backrest may comprise two side walls. A side impact protection device may be attached to at least one of the side walls. The side impact protection device may be or comprise an outwardly projecting element and / or a foldable element.

[0039] The guide rail is preferably arranged on a right and / or left side of the seat element, in particular in its rear section. The element that can be guided in and / or on and / or at the guide rail is preferably arranged on a right and / or left side of the backrest, in particular in a lower section of the backrest, for example, below the side walls. On the side of the seat element where no guide rail is arranged, another system may be arranged to allow the child seat to pivot.

[0040] The operator is preferably movable between the locking position and the release position and, at least when in the locking position, can be arranged at least partially in and / or on the guide rail, preferably at the upper end of the guide rail. The upper end of the guide rail is the end of the guide rail directed toward the backrest. This allows the operator to release the transfer of the child seat between a use position and a storage position or to lock the child seat selectively in the use position or the storage position.

[0041] In a preferred embodiment, the guide element can have a first locking region at the upper end and / or a second locking region at the lower end, wherein the first locking region is preferably larger (or longer) than the second locking region. The operator can optionally engage with the first locking region or the second locking region when in the locking position, and the operator can not engage with the first locking region or the second locking region when in the release position. Thus, the child seat can be optionally locked in the use position or in the storage position. In the use position of the child seat, the larger locking region can also be used to tilt the backrest or adjust it to the vehicle seat when the operator is in the locking position.

[0042] The second locking area is preferably designed such that it can accommodate the operator, or the operator engages, if necessary, in the second locking area, thereby ensuring a stable use position of the child seat. The second locking area can be the matching counterpart to the operator, or the operator can be the matching counterpart to the second locking area. The operator can have a shape and size such that it engages positively in the second locking area.

[0043] In a further embodiment, the rail system can be curved, in particular forming a circular arc segment. This (or other means, or more generally) eliminates the need for a physical rotation axis (while still allowing the child seat to be folded). Preferably, the guide rail guides the movement of the backrest relative to the seat element.

[0044] Preferably, the arcuate rail system, in particular forming a circular arc segment, is designed and arranged such that when the child seat is moved into the storage position, the backrest moves (slightly) upwards and towards the seat surface element, so that the side walls can be flush with the seat surface in a folded position and the child seat can be folded compactly.

[0045] In a further embodiment, at least one intermediate element can be assigned to the seat element (in particular, the seat element can comprise at least one intermediate element), which is operatively connected to the actuating element. Preferably, the intermediate element is operatively connected to the actuating element via an optionally long and / or thin and / or straight first mediating element, which preferably has a round cross-section and / or is preferably formed (consists of) metal and / or plastic (at least 50% by weight or at least 80% by weight) and / or comprises or forms a rod.

[0046] Furthermore, a second, preferably flexible and / or elongate, mediating element, preferably a transmission element, e.g. a Bowden cable and / or a belt, can be arranged on and / or on and / or in the at least one intermediate element, which is in contact with the operator and is preferably designed to selectively hold the operator in the release position or to release him into the locking position.

[0047] Preferably, the second mediating element is detachably connected to the intermediate element, more preferably the second mediating element is connected to the intermediate element via a fastening means, more preferably the second mediating element is connected to the intermediate element via at least one screw.

[0048] In a further embodiment, the actuating element can be configured such that at least a first setting and a second setting can be carried out, wherein the carrying out of the second setting preferably comprises the carrying out of the first setting (alternatively or additionally, however, the carrying out of the first setting does not comprise the carrying out of the second setting). The first setting can be carried out separately. The seat surface element preferably comprises an Isofix system, wherein the second setting is preferably an Isofix setting and / or the first setting is a folding for folding and / or unfolding the child seat, in particular in one of the embodiments described above.

[0049] Preferably, actuating the actuating element means that the actuating element is pulled in the direction of the front region of the seat element.

[0050] In a preferred embodiment, the at least one intermediate element can be moved from an initial position to a first position by (initial) actuation of the actuating element, thereby enabling a change in the inclination, in particular a folding of the child seat between the use position and the storage position. By further actuation, preferably further pulling out, of the actuating element into a second position, an adjustment of the Isofix system can be enabled (or a movement of the Isofix system can be enabled).

[0051] Alternatively, by (initial) actuation of the actuating element, the at least one intermediate element can be moved, preferably from an initial position to a first position, thereby enabling movement of the Isofix system. By further actuation, preferably further pulling out, of the actuating element into the second position, folding the child seat between the use position and the storage position can be enabled.

[0052] In a further embodiment, the operator may comprise at least one protruding, in particular cylindrical, element, preferably a locking pin, which is mounted in the seat element.

[0053] The operator, in particular the protruding element, can be biased towards the locking position of the operator, in particular by means of a spring.

[0054] In general, the child seat may preferably comprise (exactly) two projecting elements, namely one on the right side and one on the left side of the child seat.

[0055] In the absence of external forces or when the actuating element is not actuated or not actuated sufficiently, the operator can be in the locking position and can be transferred to the release position by (sufficient) actuation of the actuating element, preferably by means of one end of the second switching element, in particular a flexible element.

[0056] In one embodiment, the distance between the two protruding elements can be greater in the release position than in the locking position. It can be provided that, in the release position, the operator, in particular the protruding elements, are held in position by the second mediating element, in particular the flexible element, preferably by its ends, in particular such that the protruding elements are moved away from each other. It can further be provided that, upon completion of a (sufficient) actuation, the protruding elements move toward each other, in particular spring-driven, and the respective (assigned) operator assumes its locking position.

[0057] In one embodiment, the at least one protruding element or the two protruding elements may be configured to engage the second locking region to hold the child seat in the storage position or to engage the first locking region to hold the child seat in the use position. Alternatively or additionally, the protruding elements may be slidable in the first locking region to allow for tilt adjustment of the child seat.

[0058] Preferably, by adjusting the inclination, an angle between the upper side of the seat element and the front side of the backrest (when the child seat is in use) can be set to at least 80°, preferably at least 90°, optionally at least 100° and / or to at most 140°, preferably at most 125°, optionally at most 110°.

[0059] Preferably, the rail system comprises at least one (possibly two) guide rail(s) and at least one or two elements that can be guided in and / or on and / or at a guide rail.

[0060] The respective guide rail can be formed by the seat element and / or the respective guideable element can be formed by the backrest.

[0061] One guide element can be arranged on the right side and another guide element can be arranged on the left side of the backrest.

[0062] One guide rail may be arranged on the right side and another guide rail may be arranged on the left side of the seat element.

[0063] The respective guide element can be arranged below the side walls.

[0064] Preferably, a protruding element is arranged in each guide rail. This ensures a more stable locking in the use and storage positions, as well as improved folding and unfolding of the child seat.

[0065] The intermediate element can (additionally) be in operative connection with the Isofix system.

[0066] The intermediate element is arranged in particular on a part of the Isofix system, preferably on an Isofix element, which can be designed as a (type of) rail and is connected to the Isofix brackets.

[0067] The seat element may comprise at least one locking pin, preferably two locking pins. The at least one locking pin is in particular operatively connected to the Isofix element and can engage in recesses (or, at a given time, in one of several recesses) of the Isofix element.

[0068] The at least one locking pin can be held by the intermediate element in a locking position, in which the at least one locking pin engages with one of the recesses of the Isofix element, or can be released into a release position, in which the at least one locking pin does not engage with the Isofix element. By actuating the actuating element, the at least one locking pin can be moved from a locking position to a release position, thereby releasing movement of the Isofix system by sliding the intermediate element on the Isofix element, preferably toward the front region of the seat element, and releasing the at least one locking pin.

[0069] Versions without an intermediate element may also be provided. Likewise, additionally or alternatively, versions with only a first connecting element (possibly one on each side) or only a second connecting element (possibly one on each side) may be provided. In such versions, no Isofix system may be provided, or an existing Isofix system may not be adjustable or may only be adjustable to a limited extent, or the position of the Isofix system may be adjusted in some other way.

[0070] The above object is further achieved in particular by a method for configuring a child seat of the above type, wherein an inclination of the backrest relative to the seat surface element is adjusted and / or an anchoring device is adjusted, in particular a length thereof, and / or wherein a folding state is adjusted, in particular the child seat is transferred from an unfolded state to a folded state.

[0071] In the method, functional and / or purpose-oriented features described above and / or below can be carried out as corresponding method steps.

[0072] It should be noted that some of the figures may reveal aesthetic components in addition to technical aspects.

[0073] The invention is described below with reference to exemplary embodiments, which are explained in more detail with reference to the figures. Herein: Fig. 1a is a schematic side view of a child seat according to the invention in the position of use; Fig. 1b is a further schematic side view of the child seat according to the invention in the position of use; Fig. 2 schematic side views of a child seat according to the invention in the storage position; Fig. 3 is a schematic side view of a seat element of a child seat according to the invention; Fig. 4a is a schematic side view of a backrest of a child seat according to the invention; Fig. 4b shows an enlarged section of Fig. 4a; Fig. 5a is a schematic side view of a backrest of a child seat according to the invention; Fig. 5b shows an enlarged section of Fig. 5a; Fig. 6a is a schematic view from below of a seat element of a child seat according to the invention; and Fig. 6b shows an enlarged section of Fig. 6a .

[0074] In the following description, the same reference numerals are used for identical and equivalent parts.

[0075] Fig. 1a and Fig. 1b show a schematic side view of the child seat 2 according to the invention for attachment to a motor vehicle seat in the use position. The child seat 2 has a backrest 4, a seat element 6, an actuating element 8 (see Fig. 3 ), and an operator 10 (see Fig. 3 ) movable between a first and a second position, wherein the backrest 4 is pivotally connected to the seat element 6. A first position can be a locking position and / or a second position can be a release position, wherein the operator can be moved between the first and second positions by actuating the actuating element 8. The child seat is in an upright position, or the backrest 4 is at least approximately at a 90° angle to the seat element 6.

[0076] In Fig. 1b, the backrest 4 is directed slightly rearward, and the angle between the backrest 4 and the seat element 6 is greater than 90°, at least approximately 105°. The backrest 4 comprises two side walls 32.

[0077] The child seat may also include a side impact protection device 34 on the side wall 32 of the backrest 4 and an Isofix system 28 comprising two Isofix brackets. The side impact protection device 34 is preferably an outwardly projecting element, at least in one functional position.

[0078] Fig. 2 shows the child seat of Fig. 1a, Fig. 1b in the storage position. The child seat is in a folded position. In Fig. 2, it can be clearly seen that the backrest 4 with its side walls and the seat element are designed such that they approach each other in a folded or collapsed position, so that a comparatively small size of the child seat 2 is achieved in order to be able to transport or store it in a space-saving manner. The child seat 2 can thus be folded between a use position and a storage position when the operator (not shown) is in the release position.

[0079] Fig. 3 shows the seat surface element 6 of Fig. 1 or 2, comprising an operator 10, which is movable between a first and a second position, and an actuating element 8. The actuating element 8 can be attached to a lower side of the seat surface element 6 and can be arranged such that it is operable when the child seat 2 is fixed in the motor vehicle. The actuating element 8 can be arranged on the lower side, centrally in the front region of the seat surface element, wherein the front region of the seat surface element is the region that is directed forward towards the driver's seat or front passenger seat when the child seat is attached to the motor vehicle seat.

[0080] The actuating element 8 and the (respective) operator 10 can be mounted on opposite sides of the seat element 6. The seat element 6 can further comprise a guide rail 14. The guide rail 14 can be arranged on a right and left side of the seat element 6, particularly in its rear section. The operator 10 can be arranged at the upper end of the guide rail 14.

[0081] The seat surface element 6 can have two intermediate elements 22, which can be operatively connected to the actuating element 8. The intermediate elements 22 can be operatively connected to the actuating element 8 via a (long, thin, and straight) first mediating element 24, which can have a round cross-section. The first mediating element 24 can be made of metal and / or plastic. A second mediating element 26, which can be in contact with the operator 10, can be arranged on each of the two intermediate elements 22. The second mediating elements 26 can be designed at least partially as flexible elements.

[0082] The second mediating elements 26 can be fastened to the intermediate elements 22 by (each) at least one fastening means (e.g. screw), in particular two fastening means, in particular two screws each.

[0083] The second mediating elements 26 can hold the operator 10 in a first position or release it into a second position. The operator 10 can comprise two protruding, e.g., cylindrical, elements that can be mounted in the guide rail 14 of the seat element 6. The seat element 6 can have a guide rail 14, which, together with the element 16 that can be guided in the guide rail 14 and can be seen in Figs. 4 and 5, forms the rail system 12. The guide rail 14 is preferably arcuate or formed as a circular arc segment.

[0084] The seat element 6 may include belt guides 30 on the right and left sides of the seat element 6.

[0085] Figs. 4a / 4b and 5a / 5b show the backrest 4 from two different lateral perspectives with two side walls 32 and a side impact protection 34 arranged on one side wall 32. The backrest 4 comprises an element 16 which can be guided in the guide rail 14. This guide element 16 is shown enlarged in Figs. 4b and 5b. The element 16 which can be guided in the guide rail can be arranged on a right and left side of the backrest 4, in particular in a lower section of the backrest 4, optionally below the side walls. The guide element 16 can have a first locking region 18 at the upper end and a second locking region 20 at the lower end. The first locking region 18 can be larger (or longer) than the second locking region 20. The second locking region 20 can be arranged elongately along the guide element 16.This enables an adjustment of the inclination of the child seat 2 in the use position. The operator 10 can optionally engage with the first locking area 18 or the second locking area 20 when it is in the locked position. The operator 10 is preferably not engaged with the first locking area 18 and the second locking area 20 when it is in the release position. The guideable element 16 can be arc-shaped or formed as a circular arc segment.
