Description

Child seat device

State of the art

The invention relates to a child seat device according to the preamble of patent claim 1.

There has already been proposed a child seat apparatus having at least one seat back seat pan having at least two backrest side portions laterally bounding the seat back seat pan and at least partially defining a seating area for a child. The object of the invention is in particular to provide a generic device with improved properties in terms of comfort and intuitive adjustability. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims. Advantages of the invention

The invention is based on a child seat device having at least one backrest seat shell, which has at least two backrest side regions which laterally delimit the backrest seat shell and at least partially define a seating area for a child. It is proposed that the child seat device has at least one reducer which is height-adjustable relative to the back rest seat shell and which is intended to reduce the seating area defined by the backrest side areas. A "backrest seat shell" should be understood to mean, in particular, a shell which is part of a child seat and limits the child seat at least laterally and rearwardly outwards - -

partially a load-bearing structure of the child seat. The backrest seat shell preferably forms in particular a support region for a head, back and pelvic region of a child sitting in the child seat. The backrest seat shell is at least partially formed from a shell element, which is advantageously formed from a hard plastic or another material that appears expedient to the person skilled in the art, and advantageously from an insert embedded in the shell element, which can be formed, for example, from a polystyrene or foam , A "backrest side area" should be understood to mean, in particular, a region of the backrest seat shell which limits the backrest seat shell laterally, that is to say in particular in a transverse direction that is orthogonal to a seat direction of the child safety seat Advantageously, the shell element forms an outwardly directed outer side of the backrest side region of the backrest seat shell and preferably delimits the child seat to the outside Backrest side portion of the backrest seat shell a maximum distance from a seating area, in particular from a median plane of the child seat, on hale preferably forms on the two opposite sides of the child seat from a backrest side region, which laterally limits the child seat at least partially. Advantageously, a backrest side region is arranged at least in a shoulder and / or head region of the child seat. In principle, it is also conceivable that a backrest side region extends from a shoulder and / or head region into a pelvic and / or seat bottom region of the child seat. A shoulder portion is preferably formed as an area disposed at a height on which a child suitably allowed for the child seat is disposed in a seated state with a shoulder in the child seat. A head portion is preferably formed as an area disposed at a height on which a child suitably allowed for the child seat is disposed with his head in a seated state in the child seat. A pelvic area is preferably formed as an area which is arranged at a height on which a child suitably approved for the child seat is arranged in a state with his / her pelvis sitting in the child seat. The two opposite backrest side areas formed by the backrest seat shell are advantageously in particular the same and play - -

formed gelbildlich each other. In principle, however, it would also be conceivable for the two opposing backrest side areas formed by the backrest seat shell to be designed differently. A "reducer" is to be understood in particular as an element that can be attached to the child seat or fixed and locked in different height positions, which changes various dimensions of the child seat such as, in particular, an angle or distances, in particular in a lateral area, such that the child seat is replaced by the child seat The reducer can be adapted to children of different sizes, with the children of different sizes being transportable safely and comfortably in the child seat. "A seating area for a child" is intended in particular to mean a space available for a child sitting in the child seat, in particular one "Livingspace", in which the child is arranged in particular during a journey and in which the child can move and in which it can be transported, in particular, safely and comfortably in the motor vehicle. sondere a seating area, preferably in particular in its width, limit to be understood. The elements defining the seating area, in particular the at least one reducer, delimit the seating area laterally and thereby define it in particular in its width. In this context, a "height position" is intended in particular to elevate a position of an element, in particular of the at least one reducer, with respect to a Aufständerebene on which the child seat whose part is the child seat device, or with respect to a seat, which is the child seat This makes it possible to provide a child seat device which can be set particularly advantageously simply and intuitively to children of different sizes.Furthermore, it is proposed that the at least one reducer define seat areas of different widths in different height positions, thereby making the reducer particularly advantageous be used to adapt the child seat to different sized children.

It is further proposed that the reducer is adjustably coupled in a vertical direction with the backrest seat shell. In this case, a "vertical direction" is to be understood as meaning, in particular, a direction substantially orthogonal to the elevation plane and / or the seat surface of the child safety seat. - -

way in particular formed parallel to a main extension direction of the backrest of the child seat. By "adjustably coupled" is meant in particular that an element, in particular the at least one reducer, attached to another element, in particular the backrest seat shell, but at least in an operating state in at least one direction of movement is movable to this element As a result, the at least one reducer can be connected particularly advantageously to the backrest seat shell and thus to the child seat.

It is also proposed that the child seat device has at least one guide element which is mounted linearly displaceably in a backrest region of the backrest seat shell and to which the at least one reducer is connected. A "guide element" should be understood to mean in particular an element which has at least one guide region with which it is displaceably mounted relative to another element, in particular relative to the backrest seat shell, and has at least one receiving area for the at least one reducer, By means of which at least one reducer can be connected to the guide element, the term "linearly displaceably mounted" should be understood to mean that it can be moved, in particular along a displacement track, relative to another element. It is conceivable that the sliding track is formed by a straight line or that the sliding track is formed by a curved in at least one plane path. As a result, the reducer can be connected to the backrest seat shell in a particularly advantageous and easy height-adjustable manner.

It is further proposed that the reducer is intended for the definition of different width seat areas to be pivoted. In this context, the term "to be pivoted" should be understood to mean that it can be rotated in particular about at least one pivot axis. "Provided" is to be understood in particular to be specially designed and / or equipped. The fact that an object is intended for a specific function should in particular mean that the object fulfills and / or executes this specific function in at least one application and / or operating state. As a result, the reducer can be connected to the backrest seat shell in a particularly advantageous manner for the purpose of forming seats of different widths.

Furthermore, it is proposed that the reducer is pivotable about a pivot axis which is aligned substantially parallel to a displacement axis, , ,

around which the reducer is height adjustable. By "substantially parallel" is to be understood in particular that a deviation between two axes, in particular between the pivot axis and the displacement axis, is less than 8 degrees, preferably less than 3 degrees and in a particularly preferred embodiment is 0 degrees. As a result, the reducer can be slidably connected to the backrest seat shell in a particularly advantageous manner.

Furthermore, it is proposed that the backrest seat shell forms a guide contour, along which the reducer is guided and which adjusts a swivel angle of the reducer as a function of a height position. A "guide contour" should be understood to mean in particular a contour against which at least one correspondingly formed region of the one reducer rests and on which the reducer is guided along a height adjustment, in particular to change an orientation of the reducer a Reducer provided by the height adjustment of the at least one reducer are particularly easy to change.

It is also proposed that the guide contour has a linear course. In this context, a "linear course" is to be understood in particular to mean a course with a substantially constant pitch, thereby making it possible to achieve a particularly advantageous adjustment of the at least one reducer during a height adjustment.

It is further proposed that the reducer is spring-loaded in the direction of the externally arranged backrest side region. By "spring-loaded" is meant in particular that a spring element exerts a spring force on an element, in particular the reducer, and thereby presses or pulls it in a defined direction. A "spring element" is to be understood in particular as an element which produced in particular by elastic deformation from a rest position out a spring force against a deflection movement. A spring element is preferably designed as a mechanical spring, such as in particular a leaf spring, a spiral spring, a torsion spring, as a plate spring or another, the skilled person appear useful spring, such as in particular a hydraulic or pneumatic spring, in particular a gas spring. By "spring-loaded" is meant in particular that a spring element is a spring - -

force on an element, in particular the head support element and / or the side wing, exerts and thereby pushes or pulls in a defined direction, in particular in the direction of the comfort configuration. A "spring element" should be understood to mean, in particular, an element which generates a spring force against a deflection movement, in particular by elastic deformation from a rest position In principle, it is also conceivable that the spring element is formed integrally with the reducer, the reducer being elastically deflectable A spring element may in particular also be designed as a mechanical spring, in particular a spiral spring, a leaf spring, a torsion spring, a plate spring or another, the As a result, the at least one reducer may advantageously be pressed outward in the event of a height adjustment so as to achieve a simple pivoting.

In addition, it is proposed that the at least one reducer is arranged in a minimum position in the vertical direction at least partially below the associated Rückenlehnenseitenbe- rich. A "minimum position" is to be understood here as meaning, in particular, a height position of the at least one reducer in which the reducer has a minimal distance from a seat bottom of the child seat of the backrest side portion is disposed in the region between the associated backrest side portion and an armrest. As a result, the reducer can be formed particularly advantageous. It is further proposed that the child seat device has at least one height-adjustable head support element, which is provided to be adjustable together with the at least one reducer in a height position. A "head support element" is to be understood here in particular as an element arranged in an upper region of the backrest seat shell, which is provided for support, in particular for a lateral support of a head of a child arranged in the child seat, and for this purpose at least one substantially parallel to one Backrest region aligned center region and two laterally disposed side portions relative to the - -

Middle region are arranged angled, has. The term "height-adjustable together with the reducer" should be understood in particular to mean that the head support element is adjusted at an elevation when the reducers are adjusted, the head support element preferably being connected to the same guide relative to the back rest seat shell be formed advantageous.

It is also proposed that the child seat device has at least one spindle element, via which the at least one reducer is coupled to the backrest seat shell, wherein the spindle element is provided in a vertical adjustment of the reducer to pivot the reducer to change the seating area. A "spindle element" should be understood to mean, in particular, a rod-shaped element which has a toothing, preferably a worm toothing, at least in one partial area, which is intended to ensure that the spindle element moves relative to another element, in particular during an axial displacement along one axis The pivot axis of the spindle element rotates about the pivot axis, thereby advantageously initiating an adjustment of the at least one reducer.

It is further proposed that the backrest side areas have an extension in the vertical direction of a maximum of 250 mm. As a result, the backrest side regions can be formed particularly advantageously.

The child seat device according to the invention should not be limited to the application and embodiment described above. In particular, the child seat device according to the invention may have a different number from a number of individual elements, components and units mentioned herein for fulfilling a mode of operation described herein.

Figures 1 to 4 show a child seat device according to the invention. The child seat device is formed as a part of a child seat 10a. The child seat 10a is formed as a motor vehicle child seat. The designed as a motor vehicle child seat child seat 10a is provided so that it is attached to transport a baby or a child in a motor vehicle. The child seat 10a forms a seat bottom 12a and a seat back 14a. The child seat 10a has a seating direction that is substantially orthogonal to the seat back 14a of the child seat 10a, and that represents a direction in which a child or baby sitting or sitting in the child seat 10a is aligned with its head. The child seat 10a has a seat base, via which the child seat 10a is firmly connected to a motor vehicle seat and / or a seat of the motor vehicle. In this case, the child seat 10a is coupled with the motor vehicle seat or the seat in a manner which appears meaningful to a person skilled in the art and known from the prior art, for example via an ISOFIX connector. In this case, the child seat 10a is coupled with its seat direction in the direction of travel of the motor vehicle with the motor vehicle seat or the seat. In principle, it is also conceivable that the child seat 10a with its seat direction counter to the direction of travel of the motor vehicle , ,

is coupled with the vehicle seat or the seat. The seat bottom 12a forms a seat surface on which a child placed in the child seat 10a can be placed. The backrest 14a is disposed on a rear side of the seat bottom 12a and extends upward from the seat bottom 12a away from the seat base. The child seat 10a has a seat bottom seat pan 16a. The seat bottom seat shell 16a forms a seating area of the child seat 10a. The seat bottom seat shell 16a forms the seat base of the child seat 10a. In principle, it would also be conceivable that the seat base is formed by a separate component which can remain in a motor vehicle, in particular independently of the child seat 10a, while the child seat 10a is removed from the motor vehicle. The seat bottom seat shell 16a forms lateral support areas 18a, 20a and armrests 22a, 24a. The armrests 22a, 24a are rigid. In principle, however, it is also conceivable for the armrests 22a, 24a to be pivotable between at least two positions. The seat bottom seat shell 16a is formed of a plastic, in particular of a hard plastic. The seat bottom seat shell 16a, in particular, tensions an interior area in which functional elements of the child seat 10a, such as, in particular, a tilt adjustment and / or a fastening unit, which in particular comprises the ISOFIX connectors, are arranged.

The child seat apparatus has a seat back seat shell 26a. The seat back shell 26a forms the seat back 14a of the child seat 10a. The backrest seat shell 26a is formed of a hard plastic. The backrest seat shell 26a is modular. The backrest seat shell 26a is formed in particular from a plurality of unspecified shell elements, which are firmly connected to one another in an assembled state to form the backrest seat shell 26a. In principle, it is conceivable that at least individual elements of the backrest seat shell 26a in a defined range of motion are designed to be movable relative to other parts of the backrest seat shell 26a. In principle, it is also conceivable that the backrest seat shell 26a is integrally formed from a shell element. The seat back shell 26a has a central portion 28a in which the seat back shell 26a forms a seat back surface of the child seat 10a. On the Rückenleh- nenfläche a seated in the child seat 10 a child can be supported with his back. - -

The seat back shell 26a has a first backrest side portion 30a. The first backrest side portion 30a defines the backrest seat panel 26a on a first side. The seat back seat shell 26a has a second seat back side portion 32a. The second backrest side region 32a bounds the backrest seat shell 26a on a second side opposite the first side. The first backrest side region 30a and the second backrest side region 32a are mirror-symmetrical. In this case, the two backrest side areas 30a, 32a are formed substantially the same. In principle, it would also be conceivable that the two backrest side regions 30a, 32a are at least partially different borrowed. The backrest side portions 30a, 32a have an extent in the vertical direction of 250 mm. The backrest side portions 30 a, 32 a extend from the central region 28 a, in particular from a plane of the backrest surface, in the sitting direction of the child seat 10 a to the front. The backrest side portions 30a, 32a extend forward at least 150 mm in the seat direction. In this case, the backrest side areas 30a, 32a have, at a rear end facing the middle area 28a, an extension which, in an assembled state of the child seat 10a, extends from the armrests 22a, 24a to an upper end of the backrest seat pan 26a. In principle, it would also be conceivable that the backrest side regions 30a, 32a have at their rear ends a distance from the armrests 22a, 24a which is greater than 20 mm. The backrest side regions 30a, 32a each have an inner side 34a, 36a and an outer side 38a, 40a. The inner sides 34a, 36a and the outer sides 38a, 40a of the respective backrest side portions 30a, 32a are spaced apart from each other. The spaced apart inner sides 34a, 36a and the outer sides 38a, 40a of the backrest side portions 30a, 32a each form an inner space. The interior can advantageously be filled with an inlay, preferably an inlay made of a foam, in particular in order to increase the rigidity of the backrest side regions 30a, 32a. The inner sides 34a, 36a and the outer sides 38a, 40a of the backrest side regions 30a, 32a are each advantageously formed from at least two shell elements, which are firmly connected to each other. The outer sides 38a, 40a of the backrest side portions 30a, 32a define the backrest seat shell 26a outwardly. Advantageously, the outer sides 38a, 40a of the backrest side regions 30a, 32a limit the child seat 10a to the outside. The outer sides 38a, 40a of the backrest side portions 30a, 32a form a widest portion of the child seat 10a. The outer sides 38a, 40a have a maximum - -

Distance 42a from 440 mm apart. As a result, the child seat 10a has a maximum width of 440 mm. The maximum distance 42a is preferably measured in a horizontal plane orthogonal to the seating direction. The outer sides 38a, 40a form an outer lining of the child seat 10a in the backrest side regions 30a, 32a. In principle, it is also conceivable that a cover, for example made of a textile, is tensioned over the outer sides 38a, 40a. The inner sides 34a, 36a of the two backrest side portions 30a, 32a face each other. The inner sides 34a, 36a of the two backrest side regions 30a, 32a are spanned by a cushion unit, which is preferably formed from a foam and a cover. The inner sides 34a, 36a at least partially form a lateral support area for a child sitting in the child seat 10a with the corresponding pad unit (not shown).

The child seat device has a first reducer 46a. The first reducer 46a is arranged on a first side facing the first backrest side region 30a. The child seat apparatus has a second reducer 48a. The second reducer 48a is arranged on a second side, facing the second backrest side region 32a. The two reducers 46a, 48a are mirror-symmetrical to one another. The reducers 46a, 48a each have an inner side 64a, 66a. A transversely measured distance between the inner sides 64a, 66a of the reducers 46a, 48a defines a width of the seating area available in the area of the reducers 46a, 48a to a child sitting in the child seat 10a. The inner sides 64a, 66a of the reducers 46a, 48a face each other. Preferably, the inner sides 64a, 66a of the reducers 46a, 48a are each covered by a cushion unit, not shown, with a cover which forms a contact surface of the respective reducer 46a, 48a. The reducers 46a, 48a are arranged at an equal height. The reducers 46a, 48a are essentially the same and connected in the same way to the backrest seat shell 26a, for which reason only the reducer 46a will be described in more detail below, the description relating to the first reducer 46a being used to explain the second reducer 48a can be. The reducer 46a is formed by two interconnected shell elements 50a, 52a. In principle, it would also be conceivable that the reducer 46a is formed from a different number of shell elements 50a, 52a. The reducer 46a has an L-shaped basic shape. With a - -

short, rear end of the reducer 46a of the backrest seat shell 26a faces. A front, long portion of the reducer 46a extends forwardly away from the central region 28a of the seat back shell 26a in the seat direction. The front portion of the reducer 46a extends substantially in a same direction as the backrest side portions 30a, 32a. A front end of the reducer 46a advantageously has a distance to the central region 28a of the seat back shell 26a that is smaller than a distance of a front end of the backrest side regions 30a, 32a. The reducer 46a is pivotally connected at its rear end via a bearing 56a to the seat back shell 26a. The reducers 46a, 48a are intended to reduce a seating area available to a child seated in the child seat 10a in a width. The reducers 46a, 48a are in particular intended to define seat areas of different widths in different height positions. The reducers 46a, 48a are designed to be height adjustable. The reducers 46a, 48a are adjustably coupled in a vertical direction to the seat back shell 26a. The reducers 46a, 48a are height-adjustable connected to the seat back shell 26a. The reducers 46a, 48a are positionable at different heights to the seat bottom 12a and the seat back seat pan 26a. The reducers 46a, 48a are intended to define seat areas of different widths in different height positions. The reducers 46a, 48a define, at different heights relative to the seat bottom 12a and the seat back seat shell 26a, seat areas of different widths for a child seated in the child seat 10a. In different height positions, the inner sides 64a, 66a of the two reducers 46a, 48a have different distances. In a minimum height position, ie, in particular a height position, in which the reducers 46a, 48a have a minimum distance to the seat bottom 12a, the reducers 46a, 48a define a minimally wide seating area. A distance between the inner sides 64a, 66a of the two reducers 46a, 48a is formed in the minimum height position as a minimum width. At the minimum width, the inner sides 64a, 66a of the reducers 46a, 48a have a distance of 285 mm. In principle, it is conceivable that the inner sides 64a, 66a of the reducers 46a, 48a have a distance at the minimum width which lies in a range of 250 mm to 300 mm. In the minimum height position, ie a minimum position, the reducers 46a, 48a are advantageously arranged at least partially below the backrest side regions 30a, 32a. In a maximum height position, ie in particular a height - -

Position, in which the reducers 46a, 48a have a maximum distance to the seat bottom 12a, define the Reducer 46a, 48a a maximum wide seating area. A distance between the inner sides 64a, 66a of the two reducers 46a, 48a is formed in the maximum height position as a maximum width. At the maximum width, the inner sides 64a, 66a of the reducers 46a, 48a have a distance of 370 mm. In principle, it is conceivable that the inner sides 64a, 66a of the reducers 46a, 48a have a distance at the maximum width which lies in a range of 350 mm to 400 mm.

The child seat 10a has a guide element 54a. The guide element 54a is mounted linearly displaceable in the backrest seat shell 26a. The guide element 54a is slidably mounted in the backrest seat shell 26a. The backrest seat shell 26a forms guideways not shown in detail, in which the guide element 54a is arranged linearly displaceable. The guideways form a displacement axis, which extends in the vertical direction. The guideways preferably form, in particular, slide bearings for the guide element 54a. The reducers 46a, 48a are each pivotally connected to the guide element 54a via the bearing 56a. The reducers 46a, 48a are in particular height-adjustably connected to the backrest seat shell 26a via the guide element 54a, on which the reducers 46a, 48a are mounted. Via the guide element 54a, the reducers 46a, 48a are, in particular, height-adjustable relative to the seat bottom 12a, which is formed by the seat base seat shell 16a. The reducers 46a, 48a are adjustably vertically coupled to the seat back shell 26a. The reducers 46a, 48a are coupled in the same way to the guide element 54a via the respective bearing points 56a, for which reason only the bearing point 56a of the first reducer 46a is to be described in more detail below. In order to explain the bearing point of the second reducer 48a, which is not described in more detail, the following description of the bearing 56a of the first reducer 46a can be used.

The bearing 56a is formed by receptacles in the guide element 54a and a bearing pin 58a mounted in the receptacles, via which the reducer 46a is connected. The bearing 56a forms a pivot axis 60a, which is aligned substantially parallel to a displacement axis about which the reducer 46a is height adjustable. In particular, the pivot axis 60a is aligned substantially in a vertical direction. The pivot axis 60a is preferably substantially orthogonal to the seat - -

aligned. The reducer 46a is pivotable by more than 10 degrees about the pivot axis 60a via the bearing 56a. With its outer side 62a, the reducer 46a faces the backrest side region 30a. With its inner side 64a, the reducer 46a faces a seating area of the child seat 10a and the opposing reducer 48a, in particular the inner side 66a of the opposite reducer 48a. Advantageously, the reducer 46a is spanned on its inner side 64a with a padding unit, which is not shown here in detail. Via the bearing 56a, the reducer 46a is movable in a different manner relative to the seat back shell 26a than via the linear displacement by means of the guide element 54a. The two reducers 46a, 48a are mounted identically to the guide element 54a via their respective bearing point 56a. In principle, it would also be conceivable that the two reducers 46a, 48a are coupled in different ways to the guide element 54a. In principle, it would be conceivable that one of the two reducers 46a, 48a is rigidly and non-pivotably coupled to the guide element 54a. In principle, it would also be conceivable for one of the reducers 46a, 48a or both reducers 46a, 48a to be coupled to the guide element 54a via a linear bearing. The reducers 46a, 48a could each be arranged axially displaceable relative to the guide element 54a via at least one guide rail along a guide track. A guideway, along which the reducers 46a, 48a would be displaceable relative to the guide element 54a, would preferably be aligned, in particular, at least substantially orthogonally to the displacement axis of the guide element 54a.

The reducers 46a, 48a are intended to be pivoted to define seats of different widths. The reducers 46a, 48a are in particular intended to be pivoted during a movement in the vertical direction. The reducers 46a, 48a are intended to be pivoted at a height adjustment relative to the seat back seat pan 26a. The reducers 46a, 48a are in particular provided to be pivoted outwards in the direction of the maximum position in the direction of the respective backrest side regions 30a, 32a during a movement. The reducers 46a, 48a are provided, in particular, to be pivoted inward in each case from the corresponding backrest side region 30a, 32a when moving in the direction of the minimum position. - -

For guiding the reducers 46a, 48a, the child seat device per reducer 46a, 48a has a guide contour 68a. The guide contours 68a are provided to initiate and control a pivoting movement of a reducer 46a, 48a. The guide contours 68a are provided for predetermining the reducers 46a, 48a, when displaced in the vertical direction by means of the guide element 54a, in an angular position of the reducers 46a, 48a. The guide contours 68a are provided to predefine a defined position of the reducers 46a, 48a for each height position of the reducers 46a, 48a. By means of the guide contours 68a, the reducers 46a, 48a are arranged in a defined angular position in each height position and thereby in particular define seat areas of different widths in the different height positions. The guide contours 68a, which are assigned to the two reducers 46a, 48a, are of essentially the same design, for which reason only the one guide contour 68a assigned to the first reducer 46a is shown and described in greater detail. To explain the second reducer 48a associated, not shown guide contour, the description of the first reducer 46a associated guide contour 68a can be used. The guide contour 68a is arranged behind the reducer 46a, to which the guide contour 68a is assigned. The guide contour 68a is formed by the backrest seat shell 26a. Preferably, the guide contour 68a is formed by an element, preferably a hard plastic element, which in an assembled state with further elements forms the backrest seat shell 26a. The guide contour 68a has a main extension, which extends substantially in the vertical direction. The guide contour 68a forms a guide surface 70a, which is intended to be in direct contact with a part of the reducer 46a for guiding the reducer 46a. The reducer 46a forms a contact region 72a for contact with the guide contour 68a, in particular the guide surface 70a. The contact portion 72a is formed as a guide cam. The formed as a guide cam contact portion 72a is disposed on a rear side of the reducer 46a. The contact region 72a is formed as a protrusion. Preferably, the contact region 72a has a curved, preferably uniformly curved outer surface. In an assembled state, the contact region 72a of the reducer 46a is constantly in contact with the guide contour 68a, in particular on the guide surface 70a of the guide contour 68a.

The guide surface 70a is divided into two sections 74a, 76a, which have different inclinations. In principle, it would also be conceivable that the guide surface 70a - -

the guide contour 68a is formed only from one continuous surface or more than two partial regions 74a, 76a. In both partial areas 74a, 76a, the guide surface 70a has a surface normal, which is aligned substantially in the seat direction of the child seat 10a. The surface normals in both partial regions 74a, 76a of the guide surface 70a are directed forward. The portion 74a is formed as a lower portion of the guide surface 70a. The portion 74a is aligned parallel to the pivot axis 60a of the reducer 46a. The surface normal of the portion 74a is orthogonal to the pivot axis 60a of the reducer 46a. During a contact of the reducer 46a via its contact region 72a with the first portion 74a of the guide surface 70a, the reducer 46a is pivoted to its minimum position. During contact of the reducer 46a via its contact region 72a with the first portion 74a of the guide surface 70a, the reducers 46a, 48a define a minimally wide seating area. During an adjustment of the contact region 72a of the reducer 46a in the first subregion 74a of the guide surface 70a, the reducer 46a remains in an angular position and in particular is not pivoted. Reducers 46a, 48a define a minimum width seating area in a region where their contact regions 72a contact a corresponding lower portion 74a of the corresponding guide surface 70a. The second portion 76a immediately adjoins the first portion 74a of the guide surface 70a. The second portion 76a is inclined to the first portion 74a. The second portion 76 a extends from its lower end, with which it adjoins the first portion 74 a, to the rear, away from a front side of the child seat 10 a. The second portion 76a is inclined rearwardly from its lower end, adjacent to the first portion 74a. The second portion 76a has a uniform pitch over its entire length. The second portion 76a of the guide surface is tilted aligned with the pivot axis 60a of the reducer 46a. In different height positions, the guide surface 70a has in its second portion 76a different distances to the pivot axis 60a, about which the reducer 46a is pivotable on. The guide contour 68a has a linear course in the second portion 76a. In principle, it would also be conceivable that the second portion 76a has an irregular pitch or, for example, also forms a convex or concave course. In principle, it would also be conceivable for the guide contour to form a linear course over both partial areas 74a, 76a of its guide surface 70a. Due to the fact that in the different height positions to the pivot axis 60a, around which the reducer 46a is pivotally mounted, different - -

Chen distance is the reducer 46 a pivoted at a height adjustment in the region of the second portion 76 a. An upper end of the second portion 76a has a largest distance of the guide contour 68a from the pivot axis 60a. A lower end of the second portion 76a, and the first portion 74a of the guide contour 68a have a minimum distance of the guide contour 68a to the pivot axis 60a.

The reducers 46a, 48a are spring-loaded in the direction of the respective backrest side region 30a, 32a arranged on the outside. The child safety seat device has a spring element 78a, 80a for each reducer 46a, 48a. The spring elements 78a, 80a are provided to act on the respective reducer 46a, 48a with a spring force. The spring force of the spring elements 78a, 80a is directed in the direction of the respective, behind the reducer 46a, 48 arranged backrest side portion 30a, 32a. The reducers 46a, 48a are pressed by the spring force of the spring elements 78a, 80a in the direction of the respective backrest side region 30a, 32a. By means of the spring elements 78a, 80a, the reducers 46a, 48a are pressed with their contact areas 72a against the guide surfaces 70a of the respective guide contour 68a. The spring elements 78a, 80a introduce a moment about the pivot axis 60a into the reducers 46a, 48a, by which the reducers 46a, 48a are pivoted outwardly against the guide groove. In a height adjustment, in particular in a height adjustment upwards in the second portion 76a of the guide contour 68a, the reducers 46a, 48a are pivoted by the spring forces of the spring elements 78a, 80a to the outside. When the height is adjusted downwards, in particular in the second portion 76a of the guide contour 68a, the reducers 46a, 48a are pivoted inward against the spring forces of the spring elements 78a, 80a by the guide surface 70a. As a result, the reducers 46a, 48a can advantageously be easily pivoted in a height adjustment in order to define seat areas of different widths in the different height positions. The spring elements 78a, 80a, are formed as leaf springs. The spring elements 78a, 80a designed as leaf springs are firmly connected in particular in corresponding receptacles in the guide element 54a. In principle, it is also conceivable that the spring elements 78a, 80a are designed as other spring elements that appear appropriate to the person skilled in the art. In principle, it is also conceivable that the spring elements 78a, 80a are integrally formed. It is advantageous in particular conceivable that the integrally formed spring elements 78a, 80a are formed as a leaf spring, the - -

spans the guide member 54a and is in contact with both reducers 46a, 48a.

The child seat device has a head support element 44a. The head support member 44a is provided to form a support portion for a head of a child sitting in the child seat 10a. The head support member 44a is disposed in an upper portion of the seat back shell 26a. The head support member 44a has a central region that is aligned substantially parallel to the backrest surface of the backrest 14a. The head support member 44a has two side portions that are angled toward the center region and provide side support for a head of the child. The head support element 44a is designed to be height adjustable. The headrest element 44a is advantageously displaceable in a height position relative to the backrest seat shell 26a. The head support member 44a is adapted to be adjustable in a height position together with the reducers 46a, 48a. The head support member 44a is mounted in an upper portion of the guide member 54a. The head support member 44a is fixedly connected to the guide member 54a. The child seat apparatus has a grip portion 82a disposed on a rear side of the head support member 44a. The grip portion 82a is provided to be gripped by an operator for height adjustment of the reducers 46a, 48a and the head support member 44a. In principle, it is also conceivable that the grip region 82a is attached directly to the guide element 54a. The child seat device has a non-illustrated

Locking device on. The locking device is provided to lock the head support member 44a and the reducers 46a, 48a in the different height positions. The locking device is provided to lock the axially displaceable guide element 54a in different height positions. In this case, the locking device is provided, in particular, for locking the guide element 54a in different height positions with the backrest seat shell 26a. Advantageously, the locking device is provided to lock the guide element 54a and thereby in particular the head support member 44a and the reducers 46a, 48a continuously in different height positions. The locking device has an operating element, which is preferably arranged in the grip area 82a. An operator can use the operating element to operate the locking device and, in particular, to lock or unlock the guide element 54a. In an actuated state of the operating element, the locking device is unlocked. In an unactuated state of the operating element, the locking device is locked. is - -

unlocks the locking device by means of the control element, an operator, in particular over the grip portion 82a, a height position of the reducer 46a, 48a and the head support member 44a adjust. When the locking device is locked, a height position of the reducers 46a, 48a and the head support member 44a is fixed. In Fig. 5, a further embodiment of the invention is shown. The following description and the drawings are essentially limited to the differences between the exemplary embodiments, wherein, with regard to identically named components, in particular with regard to components having the same reference numbers, in principle also to the drawings and / or the description of the other embodiments, in particular Fig. 1 to 4, can be referenced. To distinguish the embodiments of the letter a is the reference numerals of the embodiment in FIGS. 1 to 4 adjusted. In the embodiment of FIG. 5, the letter a is replaced by the letter b.

FIG. 5 shows a child seat device according to the invention. The child seat device is formed as a part of a child seat 10b. The child seat 10b is formed as a motor vehicle child seat. The designed as a motor vehicle child seat child seat 10b is provided so that it is attached to transport a baby or a child in a motor vehicle. The child seat 10b forms a seat bottom and a seat back 14b. The child seat apparatus has a seat back seat shell 26b. The backrest seat shell 26b forms the backrest 14b of the child seat 10b. The seat back seat shell 26b has a first backrest side portion 30b. The first backrest side portion 30b defines the backrest seat shell 26b on a first side. The seat back seat shell 26b has a second seat back side portion 32b. The second backrest side region 32b limits the backrest seat shell 26b on a second side opposite the first side.

The child seat apparatus has a first reducer 46b. The first reducer 46b is arranged on a first side facing the first backrest side region 30b. The child seat device has a second reducer 48b. The second reducer 48a is arranged on a second side facing the second backrest side region 32b. The two reducers 46b, 48b are mirror-symmetrical to one another. The reducers 46b, 48b each have an inner side 64b, 66b. A transversely measured distance between the inner sides 64b, 66b of the reducers 46b, 48b is defined - -

a width of the seating area available in the area of the reducers 46b, 48b to a child sitting in the child seat 10b. The inner sides 64b, 66b of the reducers 46b, 48b face each other. Preferably, the inner sides 64b, 66b of the reducer 46b, 48b are each covered by a cushion unit not shown with a reference, which forms a contact surface of the respective reducer 46b, 48b.

The reducers 46b, 48b are arranged at an equal height. The reducers 46b, 48b are essentially the same and connected in the same way to the backrest seat shell 26b, for which reason only the reducer 46b will be described in more detail below, the description relating to the first reducer 46b being used to explain the second reducer 48b can be. The reducers 46b, 48b are provided to reduce a seating area available to a child seated in the child seat 10b in a width. The reducers 46b, 48b are in particular intended to define seat areas of different widths in different height positions. The reducers 46b, 48b are designed to be height adjustable. The child seat 10b has a guide element 54b. The guide element 54b is mounted linearly displaceable in the backrest seat shell 26b. The guide element 54b is slidably mounted in the backrest seat shell 26b. The reducers 46b, 48b are coupled directly to the guide element 54b via respective bearing points 56b, for which reason only the bearing point 56b of the first reducer 46b will be described in more detail below. The following description of the bearing 56b of the first reducer can be used to explain the bearing point of the second reducer 48b, which is not described in further detail.
